Autoria, subjetividade e poder: devolução de dados em um centro de saúde na Guariroba (Ceilândia/DF) / Authority, subjectivity and power: data devolution at a primary care unit in Guariroba (Ceilândia/Federal District/Brazil)

ResumoA devolução, restituição ou compartilhamento pode significar, dentre outras possibilidades, entregar produtos aos partícipes de um empreendimento de pesquisa/extensão. A entrega de resultados não é uma prática nova na antropologia, embora ainda seja pouco usual, sistematizada e valorizada. Neste artigo, relato e discuto uma experiência de devolução de materiais de um projeto de extensão da antropologia, que foi desenvolvido dentro de um centro de saúde, na região periférica do Distrito Federal. As reações aos materiais foram muito diferentes do esperado pela equipe do projeto, mas ainda assim permitiu fazer avançar o diálogo entre os envolvidos e, mais do que isso, permitiu que o conhecimento sobre as relações de trabalho dentro dessa instituição de saúde fosse aprofundado. Não é somente porque foi logrado o aval de comitês de ética que as negociações sobre a entrada e permanência em projetos acadêmicos estão garantidas continuamente. As relações de subjetividade, poder e autoria permeiam qualquer iniciativa antropológica, antes de começá-la e muito depois de, supostamente, terminá-la.

AbstractDevolution, restitution or sharing can mean, within other possibilities, to offer products to participants of a research or an extension project. Far from a new practice in Anthropology, returning results is still unusual, little organized and valued. This paper presents and discusses a devolution experience by an extension project in Anthropology that was developed in a primary care unit in the outskirts of Distrito Federal (Brazil). Local reactions were very different from what was expected by the project's staff, but still permitted dialogue with the health professionals and, more important, deepened our knowledge about work relations in this health institution. Even though IRB approval has been granted, negotiations about starting and continuing academic projects have to be negotiated continuously. Subjectivity, power and authority permeate any anthropological initiative from its beginning and much after it supposedly has been concluded.

Socio-demographic profile of child and adolescent users of oral health services in Victoria, Australia / Perfil sociodemográfico de crianças e adolescentes usuários de serviços públicos de cuidado de saúde bucodental em Victoria, Austrália / Perfil sociodemográfico de niños y adolescentes usuarios de servicios públicos de atención en salud bucodental en Victoria, Australia

The aim of this study was to investigate the socio-demographic characteristics of the eligible population of users of public oral health care services in the Australian state of Victoria, aged 17 years or younger. The study was conducted as a secondary analysis of data collected from July 2008 to June 2009 for 45,728 young clients of public oral health care. The sample mean age was 8.9 (SD: 3.5) years. The majority (82.7%) was between 6 and 17 years of age, and 50.3% were males. The majority (76.6%) was Australian-born and spoke English at home (89.1%). The overall mean DMFT was 1.0 (SD: 2.1) teeth, with a mean dmft of 3.16 (SD: 5.79) teeth. Data indicate that, among six year olds in the Significant Caries Index (SiC) category, the mean dmft was 6.82 teeth. Findings corroborate social inequalities in oral health outcome and provide suggestions for oral health services to develop strategies and priorities to reduce inequalities in health and well-being, and better coordinate and target services to local needs.

O objetivo deste estudo foi investigar as características sociodemográficas de usuários do serviço público de saúde bucal no Estado de Vitória, Austrália, com até 17 anos de idade. O presente estudo é uma análise de dados secundários de 45.728 sujeitos que recorreram ao serviço público de saúde bucal entre julho de 2008 a junho de 2009. A idade média da amostra foi 8,9 (DP: 3,5) anos. A maioria dos sujeitos (82,7%) apresentava entre 6 e 17 anos de idade e 50,3% eram do gênero masculino. A maioria (76,6%) havia nascido na Austrália e falava inglês em casa (89,1%). O índice CPOD médio foi 1,0 (DP: 2,1) e o ceod 3,16 (DP: 5,79). Os dados indicam que entre as crianças de 6 anos categorizadas no Significant Caries Index (SiC), o índice ceod médio foi 6,82. Os achados demonstram desigualdade social nos desfechos de saúde bucal e fornecem sugestões para que os serviços de saúde bucal desenvolvam estratégias e prioridades para reduzir tais desigualdades na saúde e bem-estar, de forma a adequar os serviços às necessidades locais.

Under-nutrition affects time to recurrence of gastroenteritis among Aboriginal and non-Aboriginal children.

This study investigated whether under-nutrition affected time to hospitalization for recurrence of gastroenteritis in Australian children. Linked hospitalization records of all infants, born in 1995 and 1996 in Western Australia, who were admitted for gastroenteritis during their first year of life (n=1001), were retrieved. A survival frailty model was used for determining the factors influencing the recurrent times over the subsequent seven years. Aboriginality and under-nutrition were significantly associated with an increased risk of recurrence (hazard ratios of 2.59 and 1.28). Hospitalizations due to gastroenteritis were common among Aboriginal children who had a higher mean re-admission rate and much shorter intervals between re-admissions than other patients. The proportion of patients with recurrence was also significantly higher for Aboriginals (38.5%) than for other patients (14.2%). Gastroenteritis remains a serious problem in Aboriginal children. This presents a complex challenge to be addressed with public-health principles, political determination and commitment, and adequate resources.

Schistosomiasis malayensis-like infection among the Penan and other interior tribes (Orang Ulu) in upper Rejang River Basin Sarawak Malaysia.

A serosurvey of various indigenous interior tribes (Orang Ulu) in upper Rejang River Basin Sarawak Malaysia, the site of a multibillion Ringgit hydroelectric power project, found 6.8% of the individual surveyed were seropositive for schistosomiasis, as determined by ELISA method using the soluble egg antigen of Schistosoma malayensis Baling strain. In all age group, the seroprevalence rate is higher (9.5%) in males than in females (4.5%) except for the 31-40 age group. Seroprevalence of schistosomiasis was found to increase with age with the above 60 age group having the highest rate followed by the 31-40 age group. Seroprevalence rate among the tribes ranges from 4.1% among the Penan to 11.6% among the Kajang. There was no seroevidence of schistosomiasis among the Ukits. A snail survey found four snail species including Brotia species, the intermediate host of the lung fluke Paragonimus westermani, however no schistosome snail host was identified. Although schistosomiasis malayensis-like infection may be endemic in the area, its public health significance remains undetermined.

Prevalence of hepatitis B infection among the primitive tribes of Andaman & Nicobar Islands.

BACKGROUND & OBJECTIVES: Andaman and Nicobar Islands, is the home of six primitive tribes. No information is available on the prevalence of hepatitis B virus (HBV) infection among them. Hence a study was undertaken with the objective of assessing the sero-prevalence of HBV infection among the four accessible tribes of these islands. METHODS: A total of 1266 serum samples were collected from four tribes i.e., Nicobarese, Shompens, Onges and Great Andamanese and tested for the presence of HBsAg and anti-HBs. Information about different risk factors associated with HBV infection was also collected from the Nicobarese tribe. RESULTS: The overall seropositivity rate of HBsAg among the Nicobarese was 23.3 per cent (95% C.I. 21.0-25.9). Hepatitis B was also found to be an important health problem among the Shompens and Onges with HBsAg positivity of 37.8 and 31.0 per cent respectively. The age-wise distribution of these serological markers among Nicobarese tribe indicate that the infection is very common in all the age groups. The sero-prevalence was also found to be very high among the children. CONCLUSIONS & INTERPRETATION: The findings of the present study indicate that hepatitis B infection is hyper endemic among the primitive tribes of these islands. Though none of the risk factors studied in the Nicobarese was found to be significantly associated with HBV infection, the fact that almost 20 per cent of the women in the reproductive age group were positive for HBsAg indicates the possibility of vertical transmission among the Nicobarese. Further studies are required to find out other modes of transmission.

The prevalence of Trichuris, Ascaris and hookworm infection in Orang Asli children.

A community study on the age and sex related prevalence, intensity infection and frequency distribution of Ascaris, Trichuris and hookworm was carried out in 205 Orang Asli (Aborigines) children (95 boys, 110 girls) aged 1-13 years. The overall prevalence of Ascaris, Trichuris and hookworm was 62.9%, 91.7% and 28.8%, respectively. Almost two-thirds of the children were infected with moderate and severe intensity infection of Trichuris, 46.3% had moderate to severe intensity infection of Ascaris. However only 1.5% had moderate intensity of hookworm infection. The prevalence and mean intensity infection (measured by eggs per g) of Ascaris was age-dependent; lower in age group 1-4 years reached peak and stable at age group 5 years and above. The prevalence of Trichuris was high in all age groups and it fluctuated with age; the mean intensity of infection of Trichuris (measured by eggs per g) was age-dependent. Hookworm infection also rose with age and reached peak at 5-6 years, following that the prevalence declined. The frequency distributions of Ascaris, and hookworm were overdispersed. A strong positive correlation (p < 0.001) were observed between Ascaris and Trichuris and between hookworm and Trichuris. A positive correlation (p < 0.01) were also observed between Ascaris and hookworm.

Seroprevalence of Sarcoptes scabiei var canis antibodies among aborigines in peninsular Malaysia.

The Aborigines or Orang Asli in Peninsular Malaysia who are still seminomadic are known to have a close association with dogs. In this study, enzyme-linked immunosorbent assay (ELISA) was used to detect anti-Sarcoptes scabiei var canis antibodies in this community as a measure of exposure to the mite. Out of 312 Orang Asli tested, 24.7% were positive for polyvalent anti-Sarcoptes antibodies. No significant difference was found between the positive rates in males (26.1%) and females (23.6%). Only 1.9% were positive for IgA and none was positive for IgE anti-Sarcoptes antibodies. Since there were very few patients with clinical manifestation of scabies, there is a possibility that continuous exposure to the dogs mite confers cross-protective immunity in the community against human scabies.

Enteroparasitosis en comunidames de la etnia yukpa del estado zulia / Enteroparasitosis in yukpas ethnic communities of Zulia State

El objetivo de la presente investigación fue determinar la prevalencia de las parasitosis intestinales en dos comunidades indígenas de la Sierra de Perijá, Estado Zulia: los pobladores de Santa Ana de Wasana y los de Kasmera. Se les dió instrucción para la adecuada recolección de la muestra fecal, obteniéndose un total, entre las dos comunidades de 70 muestras de heces, mediante métodos coproparasitológicos del examen directo, coloración temporal con lugol y por concentración (formol-etil acetato). Se encontró una alta prevalencia de enteroparasitosis en ambas comunidades; las especies de enteroparásitos más frecuentes en Santa Ana de Wasama y Kasmera fueron: Ascaris lumbricoides (36.6 por ciento y 62.1 por ciento), Trichuris trichiura (31.7 por ciento y 44.8 por ciento) y Entamoeba histolytica (26.8 por ciento y 37.9 por ciento respectivamente). Se evidenció un alto poliparasitismo en ambas comunidades

Prevalence of HTLV-I antibody among two distinct ethnic groups inhabiting the Amazon region of Brazil

HTLV-I seroprevalences of 3.63% (02/55), 12.19% (10/82) and 13.88% (10/72) were demonstrated among Tiryio, Mekranoiti and Xicrin Amazonian Indians, respectively, by the Western blotting enzyme assay (WBEI). By indirect immunoelectron microscopy (IIEM), 2 Tiriyo, 9 Mekranoiti and 6 Xicrin Amerindians were reactive. Of 44 serum samples from Japanese immigrants, none reacted by any of the techniques before mentioned. One, 8 and 6 serum samples from Tiryio, Mekranoiti and Xicrin Indians, respectively, were both WBEI and IIEM positive. Our results strongly suggest that HTLV-I and/or an HTLV-I antigenic variant circulate (s) among populations living in the Amazon region of Brazil
