Blood tests in microcytic and hypochromic anemias: differential aspects

O diagnóstico diferencial das anemias microcíticas é clinicamente importante. Na tentativa de tornar esse diagnóstico menos oneroso e mais eficiente, o uso de parâmetros dos contadores automáticos tem sido sugerido. O objetivo deste estudo foi avaliar a eficiência diagnóstica de alguns parâmetros do hemograma na diferenciação das anemias microcíticas. Foram comparados os parâmetros hematológicos de 395 pacientes portadores de anemia ferropriva, anemia de doença crônica ou talassemia menor. O número de hemácias apresentou os maiores valores combinados de sensibilidade e especificidade na diferenciação dessas anemias. Em conclusão, a contagem de hemácias pode ser útil no diagnóstico diferencial de anemias microcíticas

Percursos da constituição de uma política brasileira de educação especial inclusiva Institution course of a brazilian special education inclusive policy

Este artigo propõe-se a apresentar análises de alguns elementos que contribuem para a constituição da Educação Especial brasileira como uma política pública, dando especial foco à formulação do que tem sido denominada de política de educação especial na perspectiva inclusiva ou educação inclusiva. Para tanto, o texto é construído a partir da configuração de dois aspectos distintos, mas intimamente interligados. O primeiro refere-se ao papel do Governo brasileiro na história da educação destinada às pessoas com deficiências no Brasil. O segundo diz respeito às relações entre as políticas nacionais no campo da Educação e os acordos e compromissos internacionais. Conclui ressaltando a importância dos diferentes setores da sociedade nos embates atuais para a formulação de uma política de educação brasileira, que incorpore, de fato, toda a população.<br>This article proposes to present an analysis of some elements that contribute to a construction of Special Education as a public policy, emphasizing the formulation of what has been nominated special education inclusive perspective or inclusive education policy. For this, this text is structured considering two interrelated distinct aspects. The first refers to the Brazilian Government role in the history of education for disabled people in Brazil. The second is regarded the relationship between national policies in the education field and international agreements. The conclusion highlights the importance of involving different sectors of the society in the struggles for the development of a Brazilian educational policy that actually incorporates the entire population

NEOTROPICAL ALIEN MAMMALS: a data set of occurrence and abundance of alien mammals in the Neotropics

Biological invasion is one of the main threats to native biodiversity. For a species to become invasive, it must be voluntarily or involuntarily introduced by humans into a nonnative habitat. Mammals were among first taxa to be introduced worldwide for game, meat, and labor, yet the number of species introduced in the Neotropics remains unknown. In this data set, we make available occurrence and abundance data on mammal species that (1) transposed a geographical barrier and (2) were voluntarily or involuntarily introduced by humans into the Neotropics. Our data set is composed of 73,738 historical and current georeferenced records on alien mammal species of which around 96% correspond to occurrence data on 77 species belonging to eight orders and 26 families. Data cover 26 continental countries in the Neotropics, ranging from Mexico and its frontier regions (southern Florida and coastal-central Florida in the southeast United States) to Argentina, Paraguay, Chile, and Uruguay, and the 13 countries of Caribbean islands. Our data set also includes neotropical species (e.g., Callithrix sp., Myocastor coypus, Nasua nasua) considered alien in particular areas of Neotropics. The most numerous species in terms of records are from Bos sp. (n = 37,782), Sus scrofa (n = 6,730), and Canis familiaris (n = 10,084); 17 species were represented by only one record (e.g., Syncerus caffer, Cervus timorensis, Cervus unicolor, Canis latrans). Primates have the highest number of species in the data set (n = 20 species), partly because of uncertainties regarding taxonomic identification of the genera Callithrix, which includes the species Callithrix aurita, Callithrix flaviceps, Callithrix geoffroyi, Callithrix jacchus, Callithrix kuhlii, Callithrix penicillata, and their hybrids. This unique data set will be a valuable source of information on invasion risk assessments, biodiversity redistribution and conservation-related research. There are no copyright restrictions.
