Studies on a small collection of planorbid snails from southern south America

Snails belonging to Biomphalaria genus were collected from some regions of Southern South America as follows: Resistencia, province of Chaco, Argentina; Assumpcion, Paraguay; Department of Maldonado of Caneloni, Uruguay; and Pôrto Alegre, Rio Grande do Sul, Brazil. The material was classified as Biomphalaria peregrina (Orbigny) twice from Uruguay and once in Brazil; B. tenagophila (Orbigny), from Argentina and Brazil; and B. straminea (Dunker) in Paraguay. Negative results were obtained from the exposition of the abone refered snail specimens to miracidia of S. mansoni from Pernambuco, Brazil.

The MPs of the First Portuguese Republic: A prosopographic study

This paper summarises the results of the first systematic, detailed prosopographic study of the MPs – the deputados of the Lower Chamber - of the First Portuguese Republic (1910-1926). Data are presented both by legislature and for the overall period. Two kinds of background variables are explored: sociodemographic (birthplace, age, education and profession) and political (previous experience in other elite positions). Regime change in 1910 resulted in the replacement of the former political elite by homines novi. Most MPs of the Republican regime were born in small towns and communities, had carried out higher educational studies (with prevalence for law training), were mainly drawn from the professions (practising lawyers and doctors) and the Army, and were elected for the first-time at relatively young ages. Parliamentary turnover was high (two-thirds of the representatives held just one mandate) and a large proportion of MPs had a consistent connection (birth, family ties, occupation) to the constituencies to which they had been elected.

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.

A reabilitação respiratória para doentes com doença pulmonar obstrutiva crónica

RESUMO - CONTEXTO: A doença pulmonar obstrutiva crónica (DPOC) é uma doença de elevada prevalência a nível nacional e internacional, mas encontra-se presentemente subdiagnosticada e inadequadamente tratada. A reabilitação respiratória (RR), embora seja uma intervenção-padrão no tratamento da DPOC, é ainda pouco conhecida pelos profissionais e pelos doentes. Em Portugal existem doze instituições com programas de RR, mas terão os médicos de família conhecimento dos mesmos e do tratamento definido pelas guidelines para o doente com DPOC? Terão estes programas capacidade para dar resposta a todos os doentes que beneficiariam de RR? OBJECTIVOS: perceber como participam os doentes com DPOC em RR actualmente em Portugal; conhecer as percepções dos profissionais de saúde acerca da intervenção; identificar os factores que condicionam a acessibilidade do doente com DPOC a RR. MÉTODOS: desenvolvimento e aplicação de dois questionários: a coordenadores de USF – no sentido de avaliar o conhecimento, comportamentos e percepções dos médicos de família (MF) relativamente ao tratamento e gestão do doente com DPOC – e aos responsáveis pelos programas de RR – no sentido de avaliar a capacidade instalada de cada programa de RR, dificuldades de resposta e de participação de doentes com DPOC no mesmo. RESULTADOS: Poucos MF estiverem presentes em actividades de formação sobre a DPOC e parece existir um baixo nível de conhecimento dos MF acerca da RR, em geral, o que se verificou estar correlacionado (p=,000) com a baixa referenciação de doentes com DPOC para RR (9%). A oferta de RR é considerada pela maior parte dos profissionais (MF e responsáveis) como Insuficiente ou Muito insuficiente e o número de doentes com DPOC com recurso a RR anualmente nas instituições participantes é, na maior parte, reduzido (<80). Existe, além disso, um conjunto de importantes determinantes estruturais, associados ao profissional e ao doente que constituem barreiras à referenciação e participação dos doentes em RR. CONCLUSÕES: Verifica-se uma diferença significativa entre o número de doentes com DPOC registados nos cuidados de saúde primários (CSP) e o número de doentes com recurso a RR anualmente e apenas uma pequena percentagem de doentes com DPOC que beneficiariam da participação em RR está, actualmente, a ter acesso a esta intervenção em Portugal, o que pode ser justificado por diversos aspectos, como o grau de conhecimento do médico, dificuldades económicas do doente, entre outros.
