Zinc and vitamin A supplementation in Indigenous Australian children hospitalised with lower respiratory tract infection: a randomised controlled trial

Objective: To evaluate the efficacy of supplementation with zinc and vitamin A in Indigenous children hospitalised with acute lower respiratory infection (ALRI). Design: Randomised controlled, 2-by-2 factorial trial of supplementation with zinc and vitamin A. Setting and participants: 187 Indigenous children aged < 11 years hospitalised with 215 ALRI episodes at Alice Springs Hospital (April 2001 to July 2002). Interventions: Vitamin A was administered on Days 1 and 5 of admission at a dose of 50 000 IU (infants under 12 months), or 100 000 IU; and zinc sulfate was administered daily for 5 days at a daily dose of 20 mg (infants under 12 months) or 40 mg. Main outcome measure: Time to clinical recovery from fever and tachypnoea, duration of hospitalisation, and readmission for ALRI within 120 days. Results: There was no clinical benefit of supplementation with vitamin A, zinc or the two combined, with no significant difference between zinc and no-zinc, vitamin A and no-vitamin A or zinc + vitamin A and placebo groups in time to resolution of fever or tachypnoea, or duration of hospitalisation. Instead, we found increased morbidity; children given zinc had increased risk of readmission for ALRI within 120 days (relative risk, 2.4; 95% CI, 1.003–6.1). Conclusion: This study does not support the use of vitamin A or zinc supplementation in the management of ALRI requiring hospitalisation in Indigenous children living in remote areas. Even in populations with high rates of ALRI and poor living conditions, vitamin A and zinc therapy may not be useful. The effect of supplementation may depend on the prevalence of deficiency of these micronutrients in the population.

Study of the antibody response against Mycobacterium tuberculosis antigens in Warao Amerindian children in Venezuela

This study was aimed at investigating alternate methods for serodiagnosis of tuberculosis (TB), which are needed because bacteriologic diagnosis of childhood TB is difficult. A selection of 80 serum and saliva samples were tested from Warao indigenous children under 15 years of age; 34 high TB suspects (28 positive and 6 negative for the tuberculin skin test, TST) and 46 healthy contact children (32 positive and 14 negative for the TST). Several enzyme-linked immunosorbent assay (ELISA) serological tests were developed to test for Mycobacterium tuberculosis-specific antibodies, including serum IgA, IgG, IgE, and secretory IgA (sIgA) in saliva against 3 specific antigens (PPD, HSP60, 38 kDa). Of these, 2 antigens, PPD and 38 kDa, showed significantly higher reactivity. The sensitivity and specificity of these tests for diagnosis remained limited, between 26.5% and 38.2%, and 77.4% and 97%, respectively. Of all the samples studied and combinations realized between all isotypes and antigens combined with 3 isotypes (anti-PPD IgG, IgE, and anti-38kDa sIgA) managed to detect the largest number of patients, showing an improved sensitivity level of 64.7%, although specificity levels dropped to 81.8%. These results were compared with the Omega diagnostics commercial kit results. The commercial kits showed significantly lower reactivity (sensitivity of 20% and 13.33% to Myco G and Complex Plus, respectively) and a specificity of 100%. This study shows that in indigenous populations of Venezuela, where invasive procedures cannot be used to select samples but evaluation with a chest X-ray for radiological studies is available, the combination of 3 specific isotypes may be a useful tool to increase diagnostic accuracy with pulmonary TB in this population, when used together with clinical and epidemiological criteria.

INFECTION: ITS ECOLOGICAL DETERMINANTS AMONG CHILDREN IN NORTHERN CHILE

In developing countries, infection and malnutrition, and their interaction effects, account for the majority of childhood deaths and chronic deficits in growth and development. To promote child health, the causal determinants of infection and malnutrition and cost-effective interventions must be identified. To this end, medical examinations of 988 children (age two weeks to 14 years) living at three altitudes (coastal < 300m; sierra (TURN) 3,000m; and altiplano > 4,000m) in Chile's northermost Department of Arica revealed that 393 (40%) of the youngsters harbored one or more infections. When sorted by region and ethnicity, indigenous children of the highlands had infection rates 50% higher than children of Spanish descent living near the coast.^ An ecological model was developed and used to examine the causal path of infection and measure the effect of single and combined environmental variables. Family variables significantly linked to child health included maternal health, age and education. Significant child determinants of infection included the child's nutrient intake and medical history. When compared to children well and free of disease, infected youngsters reported a higher incidence of recent illness and a lower intake of basic foodstuffs. Traditional measures of child health, e.g. birth condition, weaning history, maternal fertility, and family wealth, did not differentiate between well and infected children.^ When height, weight, arm circumference, and subcapular skinfold measurements were compared, infected children, regardless of age, had smaller arm circumferences, the statistical difference being the greatest for males, age nine to eleven. Height and weight, the traditional growth indices, did not differentiate between well and infected groups.^ Infection is not determined by a single environmental factor or even a series of variables. Child health is ecological in nature and cannot be improved independent of changes in the environment that surrounds the child. To focus on selected child health needs, such as feeding programs or immunization campaigns, without simultaneously attending to the environment from which the needs arose is an inappropriate use of time, personnel, and money. ^

Educating for designing in and planning for country : introducing built environment students to Indigenous protocols and knowledge

Biopolitics meets Terrapolitics: Political Ontologies and Governance in Settler-Colonial Australia

Crises persist in Australian Indigenous affairs because current policy approaches do not address the intersection of Indigenous and European political worlds. This paper responds to this challenge by providing a heuristic device for delineating Settler and Indigenous Australian political ontologies and considering their interaction. It first evokes Settler and Aboriginal ontologies as respectively biopolitical (focused through life) and terrapolitical (focused through land). These ideal types help to identify important differences that inform current governance challenges. The paper discusses the entwinement of these traditions as a story of biopolitical dominance wherein Aboriginal people are governed as an “included-exclusion” within the Australian political community. Despite the overall pattern of dominance, this same entwinement offers possibilities for exchange between biopolitics and terrapolitics, and hence for breaking the recurrent crises of Indigenous affairs.

La identidad autóctona y el aprendizaje del español como segunda lengua en comunidades indígenas de Hispanoamérica : el caso de Ecuador

Cette recherche se construit autour d’un travail de terrain réalisé dans trois communautés autochtones quichuas vivant au nord de l’Équateur. Il prétend étudier l’incidence que devrait avoir la diversité culturelle et linguistique dans les politiques éducatives en milieu plurilingue et multiculturel. En Amérique hispanique, l’éducation des peuples autochtones n’a jamais été très attentive à leurs besoins spécifiques en ce qui a trait à l’apprentissage de l’espagnol comme langue seconde. En effet, les motivations des apprenants, plus instrumentales qu’intégratives, prouvent que les autochtones apprennent la langue espagnole presqu’exclusivement pour communiquer, sans vraiment être intéressés au groupe natif de cette langue. De plus, notre recherche sur le terrain avec les apprenants du peuple Otavalo nous a démontré que leur très forte identification ethnique influence l’acquisition de l’espagnol. D’une part, ils sont plus enclins à se distinguer des autres, spécialement des hispano parlants, et de l’autre, ils réussissent plus difficilement à atteindre une compétence élevée dans la langue seconde. Notre recherche conclut donc que l’éducation, qu’elle soit issue du système national ou bilingue, devrait davantage prendre en considération l’identité ethnolinguistique des nombreux enfants indigènes, afin de ne pas préjudicier leurs droits. Ceci permettrait de favoriser un apprentissage positif et significatif de l’espagnol comme langue seconde ou langue maternelle, mais tout en consolidant l’identité autochtone des apprenants.

"Pour l'amour de Dieu": des missionnaires coréens à la rencontre des Anicinabek

Cette recherche vise à comprendre comment le processus d’évangélisation fonctionne à l’époque contemporaine, caractérisée par la globalisation. Elle prend comme étude de cas les activités missionnaires d’une église coréenne évangélique dans une communauté anicinabe du Québec (Abitibi). L’analyse d’une séquence de mission estivale relate la rencontre entre deux groupes représentant chacun l’un pour l’autre l’altérité radicale : des jeunes non occidentaux et qui ne sont pas missionnaires de carrière, face à des enfants amérindiens et à leurs parents plus familiers avec le catholicisme. Du côté des missionnaires, l’analyse révèle les motivations, les objectifs, les stratégies employées et les impacts potentiels de ce temps hors du quotidien. Du côté des Anicinabek, elle montre la variété des réponses, dont la réception, principalement autour de la notion de guérison, et les limites de la réciprocité recherchée.

Saúde materno-infantil e nutrição de crianças Kaiowá e Guaraní, Área Indígena de Caarapó, Mato Grosso do Sul, Brasil

Este trabalho teve como proposta estudar o estado nutricional de crianças indígenas e conhecer condições de saúde materno-infantil. Trata-se de um estudo transversal, com uma amostra de 137 crianças de zero a 59 meses de idade, das comunidades Kaiowá e Guaraní, Área Indígena de Caarapó, Mato Grosso do Sul, Brasil. Foram realizadas entrevistas com a aplicação de um questionário sobre as condições de saúde materno-infantil. A avaliação nutricional foi obtida por meio de medidas antropométricas (peso e estatura). Verificou-se que 19,7% das mães não realizaram o pré-natal e 53,3% tiveram parto domiciliar. A ocorrência de desnutrição para o índice peso/idade foi de 18,2% e para o índice altura/idade foi de 34,1%. A proporção de crianças desnutridas quando separadas por sexo, faixa etária e escolaridade materna não apresentou diferença estatisticamente significante para ambos os índices. Este estudo evidenciou elevada ocorrência de desnutrição infantil e uma preocupante situação de saúde materno-infantil.

A formação de trabalhadores brasileiros: a experiência do Colégio Isabel

Colegio Isabel was a project that aimed to "civilize" the indigenous children who lived in the Vale do Araguaia region, Goias Province, to educate national workers and, progressively, incorporate the lands owned by the Indians in the productive process. Colegio Isabel allowed its students a marginal integration in the society, assigning them functions that the so called "civilized" people considered degrading. The egress students lived an ambiguous and marginal life, regarding the original ethnic groups and the adopted society.

A criança indígena nos estudos acadêmicos no Brasil: uma análise das produções científicas (2001 – 2012)

O presente trabalho versa sobre as Concepções de Infância Indígena presentes em estudos acadêmicos produzidos no Brasil. Para os aportes deste estudo, considerou-se como questão norteadora: quais as concepções de Infância para as diversas etnias indígenas nas produções acadêmicas no Brasil no período de 2001 a 2012? O objetivo geral consistiu em investigar as concepções de infância para as diversas etnias indígenas presentes nas produções acadêmicas no Brasil no período de 2001 a 2012, visando (1) identificar e mapear essas concepções de infância indígena nas diversas etnias presentes nas produções acadêmicas; (2) descrever o processo de educação da criança indígena nas diversas etnias indígena brasileira; (3) abordar as práticas culturais da infância indígena mencionadas nesses estudos; (4) discutir a relevância, avanços e limites desses estudos para a compreensão da infância indígena no Brasil. O caminho metodológico percorrido para o desenvolvimento deste estudo foi de caráter bibliográfico tendo como fonte Dissertações e Teses coletadas no portal da CAPES no período de 2001 a 2012 sobre a infância indígena. Para efeito de sistematização do corpus de análise desse estudo e facilitar a compreensão do material, as dissertações e teses foram organizadas em três eixos temáticos: (1) Concepção étnica de infância indígena; (2) Práticas culturais da infância indígena; (3) Educação indígena. A partir da escolha dos eixos temáticos, pensou-se em categorias que pudessem facilitar o entendimento da metodologia escolhida para essa dissertação. Então foi escolhida para cada eixo temático uma categoria, a saber: (1) Liberdade; (2) Brincadeiras; (3) Educação indígena (escolar e tradicional). No que tange às categorias, foi possível perceber quão importante foi mencioná-las neste estudo, pois entendê-las nos permitiu também trazer à tona o rico arsenal que emergem ao estudar as concepções de infância ligadas à liberdade, à brincadeira e à educação. Tais concepções nos permitiu ter um novo olhar a respeito da infância nas sociedades indígenas, a partir de avanços/limites. Os resultados mostraram também que os estudos sobre a infância e/ou a criança indígena é incipiente, principalmente no estado do Pará e isso se deve ao fato de que os pesquisadores locais ainda não despertaram o interesse pela temática em questão, sendo possível elencar algumas razões para esse “não interesse”: falta de motivação de pesquisadores nessa área, a inserção desses estudos em várias áreas do conhecimento que não necessariamente no campo da educação e o difícil acesso as comunidades. Percebeu-se também que as produções realizadas em nossa região sobre a temática infância indígena são computadas no local de origem dos pesquisadores que para cá vêm realizar seus estudos deixando a região Norte no limite das produções sobre infância indígena. Ademais, urge a necessidade de investigar a infância e/ou a criança que vivem nas mais diversas sociedades indígenas. Eis aí um grande desafio e intento a ser superado para a compreensão do universo infantil e suas lógicas de pensar a realidade, o aprendizado, como sujeito complexo e pleno, de modo que suas percepções do cotidiano da aldeia, da escola, da família, dos rituais e dos símbolos constituam-se em tarefa de suma importância.
