Estado nutricional de participantes de um Centro de Atividades para Idosos em Colombo, PR

Abstract: Objetivo: o objetivo desse estudo foi avaliar o estado nutricional de idosos participantes de um Centro de Atividades para Idosos (CATI) em Colombo, PR. Metodos: Estudo observacional transversal, com idosos com idade igual ou superior a 60 anos, de ambos os sexos, participantes ativos de um CATI em Colombo, PR. A avaliacao do estado nutricional foi realizada por meio da Mini Avaliacao Nutricional (MAN) completa. Perguntas sobre idade, comorbidades atuais, satisfacao com os relacionamentos sociais, consideracoes sobre a saude foram realizadas. Resultados: Observou-se alta frequencia de hipertensao arterial na populacao estudada, bem como, adequado estado nutricional segundo a MAN. Entretanto, avaliacoes antropometricas isoladas de circunferencia do braco e do Indice de Massa Corporal, itens participes da MAN, demonstraram importante percentual de idosos com sobrepeso e com desnutricao. Elevada satisfacao com os relacionamentos sociais e sobre a saude individual foram notadas. Conclusao: A participacao ativa dos idosos em CATI pode contribuir para o bom estado nutricional, pois os mesmos estimulam varios aspectos de saude direta e indiretamente, que contribuem para a melhoria da qualidade de vida.

Earthworm diversity in Rio Grande do Sul, Brazil.

Abstract: The knowledge regarding earthworm species richness in subtropical Brazil is limited, particularly in the state of Rio Grande do Sul (RS), where only a few sites have been sampled. In this study we assessed earthworm richness in different ecosystems of RS, prioritizing un-sampled regions. Fifteen ecosystems, including native vegetation and other ecosystems with variable levels of disturbance were sampled in 30 counties in RS, totaling 77 sampling points, mainly in the Pampa biome. Qualitative sampling was performed by handsorting soil monoliths and fixing the earthworms in 4% formalin solution. Species identification was based on morphological characters, and species richness and Shannon (H) and McIntosh (U) diversity indices were calculated for each ecosystem. Twenty-one earthworm species were identified, belonging to seven families: Glossoscolecidae (8), Rhinodrilidae (2), Ocnerodrilidae (4), Megascolecidae (4), Acanthodrilidae (1), Lumbricidae (1) and Criodrilidae (1). From these, ten are new species belonging to the genera: Glossoscolex (6), Fimoscolex (1), Kerriona (1), Eukerria (1), and one aquatic species of the Criodrilidae family, belonging to a new genus. Most of the native species ( Urobenus brasiliensis , Fimoscolex n.sp.1 and the Glossoscolex spp.) predominated in ecosystems little altered by human activity, while exotic ( Amynthas gracilis , Amynthas rodericensis , Metaphire californica , Aporrectodea trapezoides ) and peregrine species ( Pontoscolex corethrurus ) predominated in areas with more human disturbance. Native ecosystems with lower disturbance, particularly forests and native pastures had higher diversity than disturbed sites. This is the first record of A. rodericencis for Brazil and most sites represent new collection records for the known species in RS.

The Position of a Company in the Production Chain of the Pulp and Paper Industry Focusing on the Adoption of Eco-Innovation Strategies

Abstract: This study sought to gauge to what extent companies in the production chain focus on the relationship between contextual factors and the definition of eco-innovation strategies. The methodology is based on a quantitative approach using a survey in 117 companies. The results show that, in general, the companies in the sample the correlation with proactive innovation strategies was especially strengthened for those at the beginning of the production chain, with an increase in the mean for this group. This result is not in keeping with the literature when it comes to the sample data. In the literature, companies that operate in the latter stages of the production chain ought to have a greater impact at the environmental actions, as they have more direct contact with consumers of the end product. This improved performance for companies at the beginning of the production chain could be explained by the fact that these are the most polluting companies and have become the focus of environmental legislation.

Number of fragments, margin status and thermal artifacts of conized specimens from LLETZ surgery to treat cervical intraepithelial neoplasia.

Abstract: CONTEXT AND OBJECTIVE: Large loop excision of the transformation zone (LLETZ) is a nontraumatic cut and coagulation method with several advantages, but it induces thermal artifacts in the cut region. The aim here was to assess the correlations of age, number of fragments, lesion grade and degree of thermal artifacts with margin quality in conized specimens from LLETZ for cervical intraepithelial neoplasia (CIN). DESIGN AND SETTING: Cross-sectional study at Universidade Federal de Sao Paulo (Unifesp). METHODS: The records and histopathology findings of 118 women who underwent LLETZ between 1999 and 2007 were reviewed. Age, number of fragments, lesion grade, degree of thermal artifacts and margin quality were assessed. RESULTS: The patients' mean age was 27.14 years; 63.6% had been diagnosed with CIN II and 36.4% with CIN III. The lesion was removed as a single fragment in 79.6% of the cases. The margins were free from intraepithelial neoplasia in 85.6% and compromised in the endocervical margin in 6.8%. Fragment damage due to artifacts occurred in 2.5%. Severe artifacts occurred in 22.8%. Women aged 30 years or over presented more cases of CIN III (P < 0.0004). Neoplastic compromising of surgical margins and severe artifacts occurred more often in cases in which two or more fragments were removed, and in patients aged 30 years or over. CONCLUSION: CIN III in women aged 30 or over, when removed in two or more fragments during LLETZ, presented a greater number of compromised margins and greater severity of thermal artifacts.
