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.

Le gisement de Asseiceira, Portugal (Miocène supérieur) Données complémentaires sur Freiria de Rio Maior

A new upper Miocene locality at Asseiceira (Rio Maior), near the top of the "Calcários de Almoster e Santarém" unit (Almoster and Santarém limestones) is studied. Animal and plant fossils are described. Comparisons are drawn to other localities related to the same unit: Freiria and Azambujeira (middle and upper levels, both with large mammals). Small mammals from Asseiceira and Freiria point out to a rather old age amidst the upper Vallesian, MN 10 mammal-unit. This gives a fairly accurate datation for the "Calcários de Almoster e Santarém" and for the short time span of the corresponding sedimentation. Climate was warm and quite dry, with contrasting seasons and arid events. During upper Vallesian times, climate in Iberian Peninsula was varied but drier than in France, and specially so in the inner basins. However in Portugal and in Catalonia climate would he less different in comparison with that of the Rhône basin. Environmental evolution has been important: at Freiria and Azambujeira (middle level) there were mainly shallow lacustrine environments that received ressurgence waters from the nearby "Maciço calcário". Humid areas were closely surrounded by dense forests and these by broader and drier savanna or steppe areas. Still later, carbonate sedimentation ended. For some time there was still a river system with oxbows; humid areas probably were decreasing in favour of surrounding, rather dry environments. This study stressed the nced for revision of the geology of the region of Rio Maior and for a new geological mapping of that area. Environmental evolution has been important: at Freiria and Azambujeira (middle level) there were mainly shallow lacustrine environments that received ressurgence waters from the nearby "Maciço calcário".
