ABSTRACT: Maternal smoking during pregnancy is related not only to perinatal adverse events but also to important postnatal problems. Smoking is very prevalent in women with several socio-demographic factors playing an important role.
To assess the frequency of smoking as well as mothers' change in behaviours during pregnancy. To identify socio-demographic factors associated to smoking and to assess women's knowledge and sources of information about adverse effects of smoking during pregnancy.
We started a cohort study between March and October 2003 at the Maternity, Hospital Santa Maria. After an informed consent the mothers in the post natal ward were asked to fill in a questionnaire.
Four hundred and seventy five mothers responded to the questionnaire and among them 30% were smokers before pregnancy. Thirty five percent stopped smoking during pregnancy and those who continued significantly reduced the number of cigarettes per day. Smoking was less prevalent in married women, with higher educational level and with stable employment (statistically significant correlations). Forty five percent of the mothers were misinformed or had no information about the adverse effects of smoking during pregnancy. Their main source of information were the media.
Smoking prevalence was high (30%) among the respondents but the pregnancy lowered the numbers of cigarettes per day. The percentage of misinformed mothers concerned about the adverse effects of smoking during pregnancy was high (45%), which also showed that doctors' role as a source of information was surpassed by the media. The study also brought to light the need for the health professionals to improve their competences in their role on prevention of smoking during pregnancy and the postnatal period.

ABSTRACT: In recent years there has been a great increase of scientific research regarding physical exercise during pregnancy. Nevertheless, many doubts persist leading to a decrease of its practice. We aimed to evaluate the main factors that influence the practice of physical activity during pregnancy and mothers' knowledge regarding its effects. Physical activity has decreased significantly, although it was higher in nulliparous mothers, with higher educational level, employment and between 25 and 34 years old. Mothers who practiced exercise during pregnancy breastfed longer. No correlation was found concerning birth weight, gestational age or obstetric pathology. Although most mothers understand the benefits of physical activity in pregnancy, that doesn't seem to translate in an increasing practice. We believe there should be an increased awareness of health professionals in order to promote controlled physical exercise in pregnant woman.

ABSTRACT: Bacteria of the Burkholderia cepacia complex (Bcc), a group of nine related species, are opportunistic pathogens in cystic fibrosis (CF) patients, associated with a poor prognosis and patient-to-patient transmissibility. The pulmonary deterioration in Bcc-colonised/ infected patients has a heterogeneous pattern leading, sometimes, to a fulminant development - the cepacia syndrome. To evaluate the relationship between colonisation/ infection by the different Bcc species and the clinical course, the authors carried out a retrospective study of 31 CF patients with Bcc bacteria isolations followed at Hospital de Santa Maria from January 1995 to March 2006. Patients were categorised into two groups: Group I, with intermittent isolations and Group II with chronic isolations. The prevalence of Bcc species was as follows: B. cepacia 57%, B. cenocepacia 43%, B. multivorans 7%, B. stabilis 13%. Three of the patients died of cepacia syndrome. The species B. cepacia and B. stabilis, usually less frequent in CF populations of Europe and America, were isolated in a considerable percentage of the patients examined. No correlation could be established between the species and the clinical outcome. Deteriorated but not stable patients from group II, whose lung function and pulmonary exacerbation caused hospitalisation could be retrospectively analysed, exhibited significant differences in the number of hospitalisations and pulmonary function (FEV1) in the year prior to and the years following Bcc isolation. Based on the available data, it is not currently possible to outline preventive measures through the molecular characterisation of Bcc isolates, reinforcing the notion that the recommended control measures must be followed.
