Abstract The study aimed to investigate the association between early sexual initiation and alcohol consumption in adolescents. This is a cross-sectional and school-based study that had as a scenario 22 public high schools, selected by random technique and stratified by conglomerates in two stages. The total sample consisted of 1154 students regularly enrolled in schools and selected classes, aged 13 to 18 years. The collection was carried out through the application of the Youth Risk Behavior Survey, validated and translated into Brazilian Portuguese. The data were analyzed with the aid of the SPSS program version 20.0, adopting a level of significance of 5%. Multivariate analysis was used to evaluate the association between variables, and sex stratification was performed to test association with alcohol consumption patterns and the age of sexual debut. 47.7% of the sample was already sexually active, of which 24% had the first relationship with less than 15 years. Among the sociodemographic factors analyzed, only sex and religion reached significance. The stratified analysis showed a statistical association between early sexual initiation with the age of the first alcohol dose and the practice of binge in the last 30 days for both sexes. It is concluded that patterns of alcohol consumption can be important factors in the association with early sexual initiation for adolescents of both sexes, and it is necessary to implement public policies that protect this specific population.

Resumo O estudo teve por objetivo investigar associação entre a iniciação sexual precoce e o consumo do álcool em adolescentes. Trata-se de um estudo transversal e de base escolar que teve por cenário 22 escolas públicas de ensino médio, selecionadas por meio de técnica aleatória e estratificadas por conglomerados em dois estágios. A amostra total foi composta por 1154 alunos regularmente matriculados nas escolas e nas classes selecionadas, com idade entre 13 a 18 anos. A coleta ocorreu por meio da aplicação do questionário Youth Risk Behavior Survey, validado e traduzido para o português do Brasil. Os dados foram analisados com auxílio do Programa SPSS versão 20.0, adotando nível de significância de 5%. Análise multivariada foi utilizada para avaliar a associação entre as variáveis, sendo realizado estratificação por sexo para testar associação com os padrões de consumo de álcool e a idade do início sexual. 47,7% da amostra já era sexualmente ativa, sendo que destes, 24% tiveram a primeira relação com menos de 15 anos. Dentre os fatores sociodemográficos analisados, apenas o sexo e a religião atingiram significância. A análise estratificada mostrou associação estatística entre iniciação sexual precoce com a idade da primeira dose de álcool e a prática de binge nos últimos 30 dias para ambos os sexos. Conclui-se que os padrões de consumo de álcool podem se configurar como fatores importantes na associação com o início sexual precoce para adolescentes de ambos os sexos, sendo necessária a implementação de políticas públicas que protejam essa população específica.

ABSTRACT OBJECTIVE To determine the prevalence of cigarette use among adolescents and to identify associated health risk behaviors. METHODS This is a cross-sectional study with a representative sample, composed of 1059 adolescents between 13 and 19 years old, enrolled in primary and secondary public schools of Olinda, Pernambuco, in 2014. Information was obtained through self-administered questionnaires (validated version of YRBS 2007). Cigarette experimentation was defined as smoking at least once in life. Adolescents who smoked at least one day within 30 days prior to the survey were considered current smokers. Most students were female and 16 years old or older. RESULTS Almost 30% used it in life and about 10% smoked within the 30 days before the survey. Suicidal ideation (PR = 1.51, 95%CI 1.25–1.82), alcohol use (PR = 1.41, 95%CI 1.03–1.92), marijuana (PR = 1.64, 95%CI 1.37–1.96), excessive alcohol consumption (PR = 1.57, 95%CI 1.15–2.16) and sexual experience (PR = 1.78, 95%CI 1.43–2.21) have increased the risk of using cigarettes. Feelings of sadness (PR = 1.70, 95%CI 1.22–2.36), alcohol use (PR=2.40, 95%CI 1.12–5.12), excessive alcohol consumption (PR = 2.5, 95% CI 1.24–5.38), marijuana (PR = 2.31, 95%CI.57–3.39) and cocaine (PR = 1.99, 95%CI.32–3.01) increased the risk of cigarette use within the 30 days before the survey. CONCLUSIONS Cigarette use among adolescents from Olinda was high, being considered higher than the national prevalence. Possible factors associated with cigarette use were drug use (alcohol, marijuana, and cocaine) and behaviors related to sexual experience, feelings of sadness and suicidal ideation.

RESUMO OBJETIVO Estimar a prevalência do uso de drogas ilícitas e sua associação com binge drinking e fatores sociodemográficos entre estudantes adolescentes. MÉTODOS Estudo transversal com amostra probabilística por conglomerado, envolvendo 1.154 estudantes, de 13 a 19 anos de idade, da rede pública de ensino, no município de Olinda, PE, 2014. Foi utilizado o questionário Youth Risk Behavior Survey, validado para uso com adolescentes brasileiros. Para análise dos dados foi utilizado o teste do Qui-quadrado (≤ 0,05) e análise de regressão de Poisson, para estimar razões de prevalência, com intervalos com 95% de confiança. RESULTADOS O uso na vida de drogas ilícitas foi quatro vezes mais prevalente entre os estudantes que relataram o binge drinking (IC95% 3,19–5,45). Estar na faixa etária de 16 a 19 anos, ser do sexo masculino e não ter religião também foram significativamente associados ao uso de drogas ilícitas. CONCLUSÕES A prevalência do uso de drogas ilícitas na vida foi superior a outros estudos realizados no Brasil e esteve fortemente associado ao binge drinking. Esse fator mostrou associação com gênero, idade e religião.

ABSTRACT OBJECTIVE To estimate the prevalence of illicit drug use and its association with binge drinking and sociodemographic factors among adolescent students. METHODS This is a cross-sectional study with probabilistic conglomerate sampling, involving 1,154 students, aged 13 to 19 years old, from the public school system, in the city of Olinda, State of Pernambuco, Brazil, carried out in 2014. We used the Youth Risk Behavior Survey questionnaire, validated for use with Brazilian adolescents. The Chi-square test (≤ 0.05) and Poisson regression analysis were used to estimate the prevalence ratios, with 95% confidence intervals. RESULTS Use in life of illicit drugs was four times more prevalent among students who reported binge drinking (95%CI 3.19–5.45). Being in the age group of 16 to 19 years, being male, and having no religion were also significantly associated with illicit drug use. CONCLUSIONS The prevalence of use in life of illicit drugs was higher in this study than in other studies carried out in Brazil and it was strongly associated with binge drinking. This factor was associated with gender, age, and religion.

O objetivo deste ensaio clínico randomizado foi avaliar o comportamento clínico das restaurações adesivas, usando um adesivo convencional de três passos (CTP), um adesivo autocondicionante de um passo (AUP) e uma técnica simplificada da adesão úmida por etanol (AUET) antes da aplicação de uma resina composta em lesões cervicais não-cariosas. Noventa e três restaurações (31 para cada grupo) foram realizadas em 17 pacientes por um único operador. Nenhum preparo cavitário foi realizado. Depois de 6 e 12 meses, as restaurações foram avaliadas por 2 examinadores previamente treinados, utilizando critérios de Ryge modificados para retenção (kappa=1,00) e adaptação/manchamento marginal (kappa=0,81), e os resultados foram analisados pelos testes Exato de Fisher e Kruskal-Wallis, respectivamente. Não foram observadas diferenças significativas entre os grupos aos 6 e 12 meses para qualquer um dos critérios avaliados (p≥0,05). A análise intra-grupo feita pelos testes Q de Cochran (para retenção) e Wilcoxon (para adaptação/manchamento marginal) revelou diferenças significativas entre os intervalos de tempo baseline/12 meses para a adaptação marginal no AUP (p=0,0180) e manchamento marginal no CTP (p=0,0117). A análise de sobrevivência para o critério retenção realizada utilizando o teste de log-rank não apresentou diferenças significantes (p≥0,05). As restaurações feitas utilizando a técnica simplificada da adesão úmida por etanol comportaram-se igualmente às outras estratégias adesivas empregadas.

The objective of this randomized clinical trial was to evaluate the clinical performance of adhesive restorations using a three-step etch-and-rinse adhesive (TSER), a one-step self-etching adhesive (OSSE), and a simplified ethanol-wet bonding technique (EWBT) prior to the application of a composite resin in non-carious cervical lesions. Ninety-three restorations (31 for each group) were placed in 17 patients by a single operator. No cavity preparation was performed. After 6 and 12 months, the restorations were assessed by two previously trained examiners using modified Ryge criteria for retention (kappa=1.00) and marginal adaptation/staining (kappa=0.81), and the results were analyzed by Fisher's exact and Kruskal-Wallis tests, respectively. No significant differences were observed among groups at the 6- and 12-month time points for any of the assessed criteria (p≥0.05). The intra-group analysis performed by Cochran's test (for retention) and Wilcoxon test (for marginal adaptation/staining) revealed significant differences between the baseline/12-month time intervals in marginal adaptation in OSSE (p=0.0180) and in marginal staining in TSER (p=0.0117). The survival analysis for retention criteria performed using a log-rank test did not show significant differences (p>0.05). The restorations placed using the simplified EWBT performed equally well as the other adhesive strategies employed.

Trata-se de estudo metodológico que teve como objetivos adaptar o Neuropathy - and Foot Ulcer - Specific Quality of Life - NeuroQol para a língua portuguesa do Brasil, e analisar suas propriedades psicométricas. Participaram 50 pessoas com neuropatia diabética periférica e úlceras nos pés. Foram analisados os efeitos floor e ceiling, a validade convergente, a discriminante e a confiabilidade. Foi utilizado o coeficiente alfa de Cronbach para testar a confiabilidade e o de correlação de Pearson para estimar a validade convergente; o teste t-Student foi empregado para avaliar a validade discriminante, na comparação dos escores do NeuroQol entre os participantes com e sem úlceras. Constataram-se efeitos floor e ceiling em alguns domínios do NeuroQol. A confiabilidade foi satisfatória. As correlações entre os domínios do NeuroQol e SF-36 foram negativas, significativas, de moderada a forte magnitude. Os achados evidenciam que a versão brasileira do NeuroQol é confiável e válida, e que ele poderá ser utilizado como ferramenta útil para melhoria da assistência de enfermagem para as pessoas com DM.

This methodological study aimed to adapt the Neuropathy - and Foot Ulcer - Specific Quality of Life instrument - NeuroQol to Brazilian Portuguese and to analyze its psychometric properties. Participants were 50 people with peripheral diabetic neuropathy and foot ulcers. The floor and ceiling effects, the convergent and discriminant validity and the reliability were analyzed. The Cronbach’s alpha coefficient was used to test the reliability and the Pearson’s correlation coefficient to estimate the convergent validity, the Student’s t test was used to evaluate the discriminant validity in the comparison of the NeuroQol scores between participants with and without ulcers. Floor and ceiling effects were found in some domains of the NeuroQol. The reliability was satisfactory. The correlations between the domains of the NeuroQol and the SF-36 were negative, significant and of moderate to strong magnitude. The findings show that the Brazilian version of the NeuroQol is reliable and valid and may be employed as a useful tool for improving nursing care for people with DM.

Panic disorder (PD) is a pluridimensional condition that leads to psychological suffering. Due to advances in neuroimaging techniques, important contributions have been made in the understanding of the neurobiological basis of PD. However, because of diverging research designs and protocols, more conclusive data concerning the neurocircuitry of PD remain difficult to achieve. To address this issue, a bibliographical search was performed using the Institute for Scientific Information Web of Science and Medline/PubMed databases. Fifteen articles were found, and their research methodology including sample, comorbidity, gender, and pharmacological criteria were explored. Although current functional magnetic resonance imaging studies of PD constitute fundamental tools for health sciences, more uniform research protocols must be implemented to provide more consistent and conclusive data concerning the neural substrates of PD.
