How effective are brief interventions in smoking cessation: project of a cohort study in a family health care unit

ABSTRACT: Tobacco use remains the most significant modifiable cause of disability, death and illness1. In Portugal, 19,6% of the population aged ten years or more smoke3. A Cochrane review of 20087 concluded that a brief advice intervention (compared to usual care) can increase the likelihood of a smoker to quit and remain nonsmoker 12 months later by a further 1 to 3 %. Several studies have shown that Primary Care Physicians can play a key role in these interventions8,9,10. However we did not find studies about the effectiveness of brief interventions in routine consultations of Family Doctors in Portugal. For this reason we designed a Cohort Study to make an exploratory study about the effectiveness of brief interventions of less than three minutes in comparison with usual care in routine consultations. The study will be implemented in a Family Healthcare Unit in Beja, during six months. Family Doctors of the intervention group should be submitted for an educational and training program before the study begin. Quit smoking sustained rates will be estimated one year after the first intervention in each smoker. If, as we expect, quit smoking rates will be higher in the intervention group than in the control group, this may change Portuguese Family Doctors attitudes and increase the provision of brief interventions in routine consultations in Primary Healthcare Centers.

An attempt to control schistosomiasis mansoni in an endemic area by the use of Hycanthone as chemotherapeutic agent

Hycanthone in a single dose of 3.3 mg/kg of body weight was used to treal mansoni schistosomiasis in 597 persons (83%) of the population of the endemic vilage of Canabrava. Ninety two patients received a 2nd course 14 months later. There was one death em the 2nd treatment. The cure rate after one stool examination was smaller after the 2ni treatment in comparison with the first one. Re-infections did not occur imediately after the treatment. Three years later the prevalence of persons passing eggs through one stool examination was 19% compared to the 46.3% before the treatment. Adults are more resistant to the re-infections than younger.

The control of Chagas' disease transmission in Mambaí, Goiás-Brazil (1980-1981)

BHC application in Mambai in 1980 resulted in a significant decline but not elimination of domiciliated T. infestans. T. sordida peridomestic populations persist and could pose a threat to interupting human transmission of T. cruzi The results of one massive attack spray application alone was compared with this application plus one selective application as regards the presence of T. infestans in houses oneyear later. No significance difference could be detected. It is likely that for interruption of T. infestans transmission cheaper procedures can be devised than those currently in use. A further pilot study of a virgin community afflicted by T. infestans transmission is indicated since Mambai cannot be regarded as a representative areafor those still awaiting insecticide application.

Demora desde o aparecimento dos primeiros sintomas até ao diagnóstico da tuberculose pulmonar em Portugal : análise de sobrevivência

RESUMO - O presente estudo tem como objetivo contribuir para a Saúde Pública no controlo da tuberculose pulmonar (TBP), estudando a demora desde o aparecimento dos primeiros sintomas até ao diagnóstico da doença. As consequências da demora no diagnóstico podem ser fatais para os doentes e intensificar a proliferação do bacilo, influenciando a incidência da doença. Este estudo analisou os casos notificados com TBP pelo SVIG-TB, em Portugal Continental, no período de 2000 a 2009, com demora no diagnóstico de 1 a 365 dias. Foram utilizadas técnicas de estatística clássica para caracterização da base de dados e de análise de sobrevivência para caracterizar a demora até ao diagnóstico e modelar o risco de diagnóstico. As variáveis incluídas no estudo foram: género, idade, grupo etário, distrito de residência, área crítica de incidência da tuberculose, presença ou ausência da infeção pelo VIH, caso novo e reincidência, número de tratamentos anteriores, presença ou ausência de fatores de risco (álcool, tabaco, outras drogas, reclusão e sem-abrigo) e número de fatores de risco. Verificou-se que nos 35 711 casos notificados a mediana da demora até ao diagnóstico foi de 55 dias. Todas as variáveis referidas anteriormente demostraram estar correlacionadas com a demora, exceto no que diz respeito às áreas críticas ou não críticas e aos sem-abrigo. No modelo de Cox as variáveis que se mostraram relevantes ao diagnóstico foram o género em 10,2%, grupos etários, distritos, presença ou ausência de VIH em 12%, dependência alcoólica em 6,3% e dependência de tabaco em 8,8%. Estes resultados apontam para a efetividade de medidas de controlo da tuberculose, principalmente no caso de a pessoa apresentar alguns fatores de risco.
