Avaliação de projetos sociais: análise da metodologia utilizada pela Petrobrás

On the aggravation of social problems and the shortage of resources, the improvement of evaluation methods and control of its application, requiring more efficiency, efficacy, effectiveness and participation in its management, has been growing. As a result, emerges the importance of studying and developing such methodologies. The overall goal of this dissertation is to know what are the difficults to incorporate the point of view of executers and beneficiaries in evaluation process. To do so, has been done a research characterized as qualitative, with a field strategy using the case study of two social projects called Petrobras Child Program, situated in the metropolitan region of Natal, and Content Analysis technique for analyze the data. The conclusions of this work can assist in improving the process of projects evaluation financed by Petrobras, contributing with its social role, besides the possibility of encouraging a greater participation of other society actors, such as beneficiaries, in the evaluation process

Role of Serum Levels of Vascular Endothelial Growth Factor and Its Receptor in Retinopathy of Prematurity

Background: Retinopathy of prematurity (ROP) is a disorder of developing retina of low birth weight preterm infants which can lead to blindness. One theory attributes the fibrosis seen in ROP to deregulation of vascularization in the retina. Vascular endothelial growth factor (VEGF) is one of the important mediators involved in vascularization. Objectives: This study was carried out to assess the role of VEGF and its receptor in retinopathy of prematurity. Patients and Methods: Around 200 preterm infants born in SSK hospital were screened at 33 - 34 weeks. These babies were followed up according to the international classification of retinopathy of prematurity (ICROP) criteria. Those infants who developed ROP at 38 - 40 weeks were enrolled in group A while an equal number of infants who did not develop ROP were included in group B. Each group comprised of 30 subjects each. Venous sampling was carried out twice, once at 33 - 34 weeks and then again at 38 - 40 weeks. VEGF and VEGF-R2 were estimated by commercially available ELISA kits. Results: There was no statistically significant difference between the levels of VEGF and VEGF-R2 in both groups at first visit as well as the follow up visit. However, the intra-group difference was significant between the first and the final visit in VEGF and VEGF-R2 levels in the cases with ROP. In the control population, the VEGF levels were significantly lower in the follow up visit as compared to the initial visit. Conclusions: Our study demonstrates that a significant difference is seen in the serum VEGF and VRGF-R2 in the second visit of the infants with ROP demonstrating that VEGF might be responsible for the initiation and aggravation of ROP.

L’intervention en médiation familiale en présence de violence conjugale : dépistage, pratiques d’intervention, défis et préoccupations

Au Québec, la médiation familiale en contexte de violence conjugale est controversée, mais la pratique est très peu documentée et est donc mal connue. L’objectif principal de ce mémoire est de comprendre comment les médiateurs familiaux composent avec la présence de violence conjugale dans le cadre de leur pratique. Les objectifs spécifiques sont les suivants : (1) connaître comment les médiateurs familiaux dépistent la violence conjugale ; (2) savoir comment ils interviennent en présence de violence conjugale une fois cette violence dépistée ; et (3) identifier les défis et les préoccupations rencontrées par les médiateurs dans ces dossiers. Cette étude qualitative fut menée auprès de 8 médiateurs issus des domaines juridique et psychosocial. Les participants furent rencontrés dans le cadre d’entrevues semi-dirigées. Les médiateurs rencontrés insistent sur l’importance d’offrir une formation avancée portant sur la problématique de la violence conjugale et sur les outils de dépistage à tous les médiateurs au Québec et de bonifier la formation actuelle en adressant la dangerosité, le risque de récidive et d'aggravation de la violence et l’appréciation du risque d’homicide conjugal. Les résultats de l’étude suggèrent également l’importance de bien différencier le terrorisme conjugal de la violence situationnelle et de mettre en place des pratiques d’interventions spécifiques à chacun de ces types de violence. La médiation familiale en présence de violence conjugale devrait être un champ de pratique spécialisé et le travail de collaboration avec les ressources spécialisées en violence conjugale nécessiterait d’être renforcé.

Study of the allergenic profile of pollen from Platanus hybrida in the city of Evora, Portugal

Background and Aim: Although grasses and olive are the most relevant allergenic species in the Alentejo region, aggravation of allergic symptoms in the early spring, unrelated with those species pollen seasons, has been reported, particularly in urban environment. Plane trees, hence pollen, are highly abundant in the city of Évora, nonetheless allergen pollen profile has not yet been evaluated. The aim of this work was to characterize the allergen profile of pollen from Platanus hybrida, one of the most representative species in Evora showing pollination prior to the main pollen season in Alentejo. Methods: Pollen from Platanus hybrida and Dactylis glomerata was extracted with ammonium bicarbonate buffer, lyophilized and stored at -80ºC until analysis. Protein content was determined by the Bradford method. SDS-PAGE followed by western blot, using allergic patient sera (obtained from the Hospital do Espírito Santo de Évora – HESE), were performed to evaluate the allergen profile of the pollen. Sensitization and cross-reactivity was assessed by solid phase immunoblot. Results: Half of the patient exhibited sensitization to pollen extracts of P. Hybrida. Western blot have shown several immunoreactive bands in the Mr 10-90 kDa range. Immunoreactive bands were also observed in the protein profile according to the pI in the pI range 4.0-6.1. Cross-reactivity of P. hybrida with D. glomerata was found. Although several bands are common to D. glomerata, a band with ~50kDa was observed in P. hybrida but not in D. glometata. Conclusion: These results evidenced allergens found in P. hybrida pollen. Moreover, cross–reactivity between P. hybrida and highly allergenic species such as D. glomerata was found which probably contributes for aggravation of pollinosis in the early spring.

Allergenic profile of Quercus rotundifolia pollen in Alentejo, Portugal

Background and Aim: Grasses and olive are the most relevant allergenic species in the Alentejo region. However, aggravation of allergic symptoms has been reported in the early spring, before grass and olive pollen seasons. Quercus pollen is the most abundant pollen type in the early spring in Alentejo, nonetheless its allergen profile has not yet been evaluated. The aim of this work was to characterize the allergen profile of pollen from Quercus rotundifolia among the most representative species showing pollination in April, prior to the main pollen season in Alentejo. Methods: Pollen from Quercus rotundifolia, Olea europaea and Dactylis glomerata was extracted with ammonium bicarbonate buffer, lyophilized and stored at -80ºC until analysis. Extract from Quercus ilex pollen was kindly offered by Bial. Protein content was determined by the Bradford method. SDS-PAGE followed by western blot, using allergic patient sera (obtained from the Hospital do Espírito Santo de Évora – HESE), were performed to evaluate the allergen profile of the pollen. Sensitization and cross-reactivity was assessed by solid phase immunoblot. Results: Most of the patient evidenced sensitization to pollen extracts of Q. rotundifolia. Protein profile of Q. rotundifolia has shown several bands in the Mr 10-90 kDa, mostly overlapping with Q. ilex. Western blot have shown several immunoreactive bands. Immunoreactive bands were also observed in the protein profile according to the pI in the range 4.0-6.1. Cross-reactivity between Q. rotundifolia with O. europaea and D. glomerata was found. Conclusion: These results evidenced allergens found in Q. rotundifolia pollen. It also shows that protein profile of Q. rotundifolia and Q. ilex are mostly alike suggesting that similarities in allergen profile are expected. Moreover, cross–reactivity between Q. rotundifolia and highly allergenic species such as O. europaea and D. glomerata was found which probably contributes to the aggravation of pollinosis in the early spring. Acknowledgments: This work was supported by FEDER through the “Programa Operacional Fatores de Competitividade – COMPETE” (Strategic projects of ICAAM and ICT 2013-2015). We also aknowledge Bial-Aristegui for supplying pollen and extract samples of Q. ilex.

Perfil em alergénios do pólen de Platanus hybrida

Objetivos: O plátano (Platanus hybrida) é uma árvore frequentemente utilizada em ambiente urbano, com fins ornamentais. Sendo uma árvore de grande porte, produz pólen em grande quantidade. Embora seja responsável por níveis de exposição a pólen elevados no início da primavera, que são coincidentes com queixas da população, o seu potencial alergénico está pouco caracterizado. Este trabalho teve, assim, como objetivo caracterizar o perfil em alergénios do pólen de plátano na cidade de Évora, Alentejo. Métodos: Prepararam-se extratos de amostras de pólen de Platanus hybrida ou Dactylis glomerata utilizando tampão bicarbonato. Os extratos foram liofilizados e conservados a -80ºC. O conteúdo em proteínas foi determinado pelo método de Bradford. O perfil em alergénios foi avaliado por western blot utilizando soros humanos (obtidos mediante consentimento informado de doentes do Hospital do Espírito Santo de Évora – HESE). Resultados: Observou-se teste positivo a P. hybrida em metade dos soros testados. O perfil em proteínas de P. hybrida exibiu diversas bandas imunorreativas com massas moleculares compreendidas entre 10-90 kDa e com pI no intervalo 4,4-7,0. Foram encontradas imunorreativas comuns a Q. rotundifólia e/ou a D. glomerata. Duas bandas identificadas na gama de 50kDa e 60 kDa parecem específicas de P. hybrida. Também se registou reatividade cruzada com D. glomerata. Conclusões: Este trabalho evidencia alguns alergénios encontrados em pólen de P. hybrida. Para além disso mostra ainda a existência de reatividade cruzada com pólen de gramíneas. Estes resultados sugerem que o pólen de plátano, dada a sua grande abundância na cidade de Évora, poderá contribuir para o agravamento a sintomatologia da população que sofre de polinose, em particular no início da primavera. Agradecimentos: Este trabalho foi financiado por fundos do FEDER através do Programa Operacional Fatores de Competitividade – COMPETE”.
