Atribuciones causales y nivel educativo familiar en la comprensión del desempeño escolar en alumnos portugueses
Este artigo analisa o contributo específico do nível educativo familiar e das atribuições causais para o bom e fraco rendimento escolar dos alunos na explicação do seu desempenho nas disciplinas de Língua Portuguesa e de Matemática numa amostra de 2.082 alunos do ensino público de 11 escolas de Portugal, incluindo as Regiões Autónomas dos Açores e da Madeira. As atribuições causais foram avaliadas por meio do Questionário das Atribuições Causais para os
Resultados Escolares (QARE). O nível educativo familiar foi estimado levando em conta o nível escolar do progenitor com maior habilitação escolar. As classificações obtidas pelos alunos nas disciplinas de língua portuguesa e matemática foram também examinadas. Os resultados apontam para correlações estatisticamente significativas, destacando as atribuições na capacidade para a explicação do rendimento escolar, situação que contrasta com a atribuição dos níveis de rendimento a variáveis externas ao aluno. A análise de regressão permite associar 34,5% da variância no rendimento
conjunto em Língua Portuguesa e em Matemática no ensino básico, assim como 21,3% no ensino secundário, às
dimensões atribucionais e ao nível educativo familiar. Implicações educacionais são derivadas a partir dos achados.This paper analyzes the contribution of both family educational level and causal attributions in explaining students´
academic performance in Mathematics and Portuguese Language in a sample of 2.082 public school students from mainland Portugal and the Azores and Madeira regions. Causal attributions were assessed by the Causal Attributions Questionnaire for School Results (QARE). The family educational level was estimated taking into account the educational
level of the parent with higher academic degree. The academic grades obtained by students in mathematics and portuguese language were also considered. The results show statistically significant correlations between variables. Internal causal attributions such as capacity and study methods were predominant to explain school performance in the sample and stood out in contrast to external attributions explanations. Regression analyses revealed that 34.5% of the
variance in the combined achievement on Portuguese Language and Mathematics in primary education and 21.3% in secondary education could be explained by both the attributional dimensions and family education level. Some educational implications are present taking these data.Este artículo analiza la contribución específica del nivel educativo familiar y de las atribuciones causales para el buen y el

Risk factors for chronic non-communicable diseases and the CARMEN Initiative: a population-based study in the South of Brazil
Income inequality and health: multilevel analysis of Chilean communities
Study objective: The evidence supporting the effect of income inequality on health has been largely observed in societies far more egalitarian than the US. This study examines the cross sectional multilevel associations between income inequality and self rated poor health in Chile; a society more unequal than the US. Design: A multilevel statistical framework of 98 344 people nested within 61 978 households nested within 285 communities nested within 13 regions. Setting: The 2000 National Socioeconomic Characterization Survey (CASEN) data from Chile. Participants: Adults aged 18 and above. The outcome was a dichotomised self rated health (0 if very good, good or average; 1 if poor, or very poor). Individual level exposures included age, sex, ethnicity, marital status, education, employment status, type of health insurance, and household level exposures include income and residential setting (urban/rural). Community level exposures included the Gini coefficient and median income. Main results: Controlling for individual/household predictors, a significant gradient was observed between income and poor self rated health, with very poor most likely to report poor health (OR: 2.94) followed by poor (OR: 2.77), low (OR: 2.06), middle (OR: 1.73), high (OR: 1.38) as compared with the very high income earners. Controlling for household and community effects of income, a significant effect of community income inequality was observed (OR:1.22). Conclusions: Household income does not explain any of the between community differences; neither does it account for the effect of community income inequality on self rated health, with more unequal communities associated with a greater probability of reporting poor health

An intervention to improve diabetes control in Chile
Previous research has shown that controlling blood glucose improves short-term and long-term outcomes among patients who have either type 1 or type 2 diabetes. The objective of this study was to investigate, in a developing country, the effectiveness of an intervention that included patient education, self-monitoring of blood glucose, and determination of the level of glycosylated hemoglobin (HbA1c).
The patients were grouped into three categories, taking into account such clinical manifestations as the duration of their diabetes, its treatment, and their hospitalization history. After the inclusion and exclusion criteria were applied, the persons were randomly assigned to two groups. One group (210 patients) received the educational intervention, and the control group (206 patients) received customary care. The intervention group received educational information needed for self-monitoring of blood glucose and for the self-evaluation of positive and negative behaviors related to metabolic control of the disease.
The two groups were similar with respect to age (mean of 52.3 and 50.5 years) and to the proportion of patients with type 1 diabetes (13.8% and 16.0%). There were no initial differences in the average concentration of HbA1c in the two groups (8.9% +/- 0.1% and 8.9% +/- 1.4%). A total of 50 persons dropped out of the study, 14.8% of those in the intervention group and 9.2% of those in the control group. In the intervention group, compliance with dietary recommendations increased by 43.5%, from 57.5% at the beginning of the study to 82.5% at the end (P < 0.001); in the control group there was also a change but it was not significant. Although patients with a high initial HbA1c concentration were underrepresented in this study, the average HbA1c concentration declined significantly in the intervention group (-0.4% +/- 1.1%, P = 0.001) but not in the control group (-0.1% +/- 0.1%).
In one developing country, educating patients about diabetes helped improve metabolic control, a fact that can be attributed mainly to the intervention's positive impact on those persons' diet

Pleural empyema. Retrospective review of 343 patients Empiema pleural en 343 casos con tratamiento quirúrgico: Características, resultados inmediatos y factores asociados a morbilidad y mortalidad
Background: Pleural empyema still has a dismal prognosis. Aim: To describe features and prognostic factors of patients with pleural empyema subjected to surgical procedures. Material and Methods: Retrospective review of 343 patients with pleural empyema (mean age 52 years, 71% males), that were subjected to any type of surgical procedure. Criteria for diagnosis of empyema were a positive culture, a fluid pH of less than 7.2 or a compatible macroscopic appearance of the fluid. Results: Empyema was secondary to pneumonia in 243 patients (71%), secondary to surgical procedures in 41 patients (12%), secondary to trauma in 19 patients (5.5%), secondary to a lung abscess in 10 patients (3%), tuberculous in 10 patients (3%), neoplastic in two cases (0.6%), secondary to pneumothorax in 2 cases (0.6%) and of unknown origin in 13 patients (4%). A microorganism was isolated from pleural fluid in 89 patients (26%). The surgical procedures performed were 251 decortications by thoracotomy (73%), 7
Parapneumonic empyema: Characterization and factors associated with morbidity and mortality in 242 surgical cases Empiema paraneumónico: Caracterización y factores asociados a morbi-mortalidad en 242 casos tratados quirúrgicamente
Objectives: To describe and evaluate factors associated with morbidity and mortality in surgically treated parapneumonic empyemas (PNE). Method: Retrospective review between January 2000 and August 2006. We described clinical features and we performed univariate and multivariate analysis to find the factors associated with morbidity and mortality. SPSS 15.0 program was used in the statistical analysis. Results: 242 of 343 surgically treated empyemas (70.6%) were paraneumonic. Of these 165 (68.2%) were men, average age 52.1 years, 229 (94.6%) were community-acquired pneumonia (CAP) and 13 (5.4%) nosocomial. Germs were isolated in pleural fluid in 57 (23.6%). Surgical procedures were: 183 (75.6%) decortications, 49 (20.2%) pleurotomies, 7 (2.9%) video-assisted surgery and 3 (1.2%) decortications with pulmonary resection. Complications occurred in 65 cases (26.9%) and 16 patients died (6.6%). We found variables associated with morbidity and mortality. Conclusions: PNE is the most common
