Engaging with theories of dialogue and voice: Using Bakhtin as a framework to understand teaching and learning Indigenous Australian women's performance

In this paper I explore the Indigenous Australian women's performance classroom (hereafter ANTH2120) as a dialectic and discursive space where the location of possibility is opened for female Indigenous performers to enter into a dialogue from and between both non-Indigenous and Indigenous voices. The work of Bakhtin on dialogue serves as a useful standpoint for understanding the multiple speaking positions and texts in the ANTH2120 context. Bakhtin emphasizes performance, history, actuality and the openness of dialogue to provide an important framework for analysing multiple speaking positions and ways of making meaning through dialogue between shifting and differing subjectivities. I begin by briefly critiquing Bakhtin's "dialogic imagination" and consider the application and usefulness of concepts such as dialogism, heteroglossia and the utterance to understanding the ANTH2120 classroom as a polyphonic and discursive space. I then turn to an analysis of dialogue in the ANTH2120 classroom and primarily situate my gaze on an examination of the interactions that took place between the voices of myself as family/teacher/student and senior Yanyuwa women from the r e m o t e N o r t h e r n T e r r i t o r y A b o r i g i n a l c o m m u n i t y o f B o r r o l o o l a as family/performers/teachers. The 2000 and 2001 Yanyuwa women's performance workshops will be used as examples of the way power is constantly shifting in this dialogue to allow particular voices to speak with authority, and for others to remain silent as roles and relationships between myself and the Yanyuwa women change. Conclusions will be drawn regarding how my subject positions and white race privilege affect who speaks, who listens and on whose terms, and further, the efficacy of this pedagogical platform for opening up the location of possibility for Indigenous Australian women to play a powerful part in the construction of knowledges about women's performance traditions.

Association of acanthosis nigricans with race and metabolic disturbances in obese women

Acanthosis nigricans (AN) has been recognized as a marker of insulin resistance and diabetes mellitus. We have compared frequency of race and metabolic disturbances in obese women with several degrees of AN (AN group, N = 190) to a group without AN (non-AN group, N = 61) from a mixed racial population. The groups were similar regarding age and body mass index. All patients (except the diabetic patients) underwent an oral glucose tolerance test (75 g). The racial distribution of this population was 35.1% white, 37.8% mulatto and 27.1% black and the frequency of AN was 62.5, 82.1 and 83.8%, respectively, higher in black versus white (P = 0.003) and mulatto versus white (P = 0.002) women. The frequencies of diabetes mellitus and impaired glucose tolerance were 5.8 and 12.6% in the AN group and 1.6 and 8.2% in the non-AN group, respectively (P>0.05). Fasting glucose, ß cell function determined by the homeostasis model of assessment (HOMA), fasting insulin and insulin area under the curve were similar for the AN and non-AN groups. A higher HOMA insulin resistance was observed in the AN group compared to the non-AN group (P = 0.02) and in the subgroup of highest degree of AN compared to those with other degrees. The mean lipid levels and the frequency of dyslipidemia were similar for the two groups. AN was strongly associated with the black or mulatto rather than the white race, even after taking into account the effect of age, body mass index and HOMA insulin resistance.

Different disparities of gender and race among the thrombotic thrombocytopenic purpura and hemolytic-uremic syndromes

Thrombotic thrombocytopenic purpura (TTP) and hemolytic-uremic syndrome (HUS) represent multiple disorders with diverse etiologies. We compared the gender and race of 335 patients enrolled in the Oklahoma TTP-HUS Registry across 21 years for their first episode of TTP or HUS to appropriate control groups. The relative frequency of women and white race among patients with TTP-HUS-associated with a bloody diarrhea prodrome and the relative frequency of women with quinine-associated TTP-HUS were significantly greater than their control populations. The relative frequency of women and black race among patients with idiopathic TTP and TTP-associated with severe ADAMTS13 deficiency was significantly greater than their control populations. The relative frequency of black race among patients who had systemic lupus erythematosus (SLE) preceding TTP was significantly greater than among a population of patients with SLE, and the relative frequency of black race among patients with other autoimmune disorders preceding TTP was significantly greater than their control population. No significant gender or race disparities were present among patients with hematopoietic stem cell transplantation-associated thrombotic microangiopathy, TTP associated with pregnancy, or TTP associated with drugs other than quinine. The validity of these observations is supported by the enrollment of all consecutive patients across 21 years from a defined geographic region, without selection or referral bias. These observations of different gender and race disparities among the TTP-HUS syndromes suggest the presence of different risk factors and may serve as starting points for novel investigations of pathogenesis.

How doctors' communication style and race concordance influence African-Caribbean patients when disclosing depression

Objective: To determine the impact of doctors' communication style and doctor-patient race concordance on UK African-Caribbeans' comfort in disclosing depression. Methods: 160 African-Caribbean and 160 white British subjects, stratified by gender and history of depression, participated in simulated depression consultations with video-recorded doctors. Doctors were stratified by black or white race, gender and a high (HPC) or low patient-centred (LPC) communication style, giving a full 2. ×. 2. ×. 2 factorial design. Afterwards, participants rated aspects of doctors' communication style, their comfort in disclosing depression and treatment preferences. Results: Race concordance had no impact on African-Caribbeans' comfort in disclosing depression. However a HPC versus LPC communication style made them significantly more positive about their interactions with doctors (p = 0.000), their overall comfort (p = 0.003), their comfort in disclosing their emotional state (p = 0.001), and about considering talking therapy (p = 0.01); but less positive about considering antidepressant medication (p =0.01). Conclusion: Doctors' communication style was shown to be more important than patient race or race concordance in influencing African Caribbeans' depression consultation experiences. Changing doctors' communication style may help reduce disparities in depression care. Practice Implications: Practitioners should cultivate a HPC style to make African-Caribbeans more comfortable when disclosing depression, so that it is less likely to be missed.

Digital vasculitis in systemic lupus erythematosus: a minor manifestation of disease activity?

The objective of this study is to determine if digital vasculitis (DV), a clinical manifestation with a high systemic lupus erythematosus disease activity index (SLEDAI) score, is associated with lupus severity. DV and other clinical manifestations defined according to the SLEDAI were evaluated in 168 consecutive patients with systemic lupus erythematosus (SLE). Two groups were defined according to presence (DV+, n = 27) or absence of DV (DV-, n = 141) at the time of evaluation. The exclusion criterion was the presence of antiphospholipid syndrome (Sapporo`s criteria). The two groups were comparable with regard to age (P = 0.09), gender (P = 1.00), white race (P = 0.81), and disease duration (P = 0.78). Compared to the DV-group, the DV+ group had a significantly higher frequency of mucocutaneous manifestations (66.7 vs. 39.0%, P = 0.01), haematological abnormalities (22.2 vs. 6.4%, P = 0.02) and constitutional symptoms (11.1 vs. 0.7%, P = 0.01). Renal and neurological involvements were similar in both groups ( P = 0.57 and P = 1.00, respectively). The evaluation of each SLEDAI parameter confirmed that the DV+ group had higher frequencies of mild manifestations, such as new rash (P = 0.02), alopecia (P = 0.02), oral ulcers (P = 0.045), fever (P = 0.01) and leucopenia (P = 0.005). In contrast, both groups had similarly increased anti-dsDNA (P = 0.78) and decreased complement levels (P = 0.29). In conclusion, DV in patients with SLE identifies a subgroup of a mild disease. The high `weighted` index attributed to this alteration in the SLEDAI score should therefore be revised. Lupus (2009) 18, 990-993.

Cutaneous vasculitis in systemic lupus erythematosus: association with anti-ribosomal P protein antibody and Raynaud phenomenon

Ninety-one consecutive systemic lupus erythematosus (SLE) patients (American College of Rheumatology criteria) with a history of cutaneous vasculitis were compared to 163 SLE controls without this clinical manifestation from July to December 2007 in order to determine the possible clinical and serological association of this manifestation. Data were obtained in an ongoing electronic database protocol and autoantibodies to anti-double-stranded DNA, anti-Sm, anti-RNP, anti-Ro/SS-A, anti-La/SS-B, and anticardiolipin and ribosomal P protein antibody (anti-P) were detected by standard techniques. Exclusion criteria were the presence of anti-phospholipid syndrome or antibodies, Sjogren syndrome, and a history of thrombosis. The mean age (38.5 +/- 11.5 vs. 37.8 +/- 11.6 years, p = 0.635), disease duration (12.5 +/- 7.8 vs. 11.8 +/- 7.9 years, p = 0.501), and frequency of white race (71.4% vs. 70.5%, p = 0.872) and female sex (96.8% vs. 93.7%, p = 0.272) were comparable in both groups. The vasculitis group had a higher frequency of malar rash (97.9% vs. 87.4%, p = 0.004), photosensitivity (91.4% vs. 81.6%, p = 0.030), and Raynaud phenomenon (RP; 27.7% vs. 7.5%, p < 0.001), whereas all other clinical manifestation including renal and central nervous system involvements were similar to the control group. Laboratorial data revealed that only anti-P (35.1% vs. 12.1%, p < 0.001) was more frequent in patients with vasculitis. In a multivariate logistic regression model, cutaneous vasculitis was associated to the presence of RP (OR = 3.70; 95% confidence interval [CI] = 1.73-8.00) and anti-P (OR = 3.42; 95% CI = 1.76-6.66). In summary, SLE cutaneous vasculitis characterizes a subgroup of patients with more RP and anti-P antibodies but not accompanied by a higher frequency of renal and central nervous system involvements.

Comparison of pelvic floor muscle strength between women undergoing vaginal delivery, cesarean section, and nulliparae using a perineometer and digital palpation

Objectives. To compare pelvic floor muscle (PFM) strength between women undergoing vaginal delivery, cesarean section, and nulliparae, investigating the factors associated with PFM strength, and observing the correlation between vaginal digital palpation and use of a perineometer. Methods. A cross-sectional study was conducted, including 31 women following vaginal delivery, 30 women following cesarean section, and 30 nulliparous women. PFM strength was measured by vaginal digital palpation and use of a perineometer. Multiple linear regression analysis with adjustment for covariables was used to compare the mean PFM strength and identify its associated factors. Results. The mean PFM strength of women undergoing vaginal delivery and cesarean section was 25.6 +/- 14.5 cmH(2)O and 39.6 +/- 22.0 cmH(2)O (p < 0.01, adjusted for covariables), respectively. A correlation was observed between measurements of PFM strength obtained by vaginal digital palpation and use of a perineometer (tau = 0.82; p < 0.01). The non-white race/ethnicity was negatively associated with PFM strength (coefficient: -10.2424; p = 0.02). Conclusions. A lower PFM strength was observed in women with a history of vaginal delivery compared to those undergoing cesarean section. Non-white race/ethnicity negatively affected PFM strength. Our data suggest that vaginal digital palpation may be used in clinical practice because of its expressive correlation with use of a perineometer.

Modulation of Mediotemporal and Ventrostriatal Function in Humans by Delta 9-Tetrahydrocannabinol A Neural Basis for the Effects of Cannabis sativa on Learning and Psychosis

Context: Cannabis sativa use can impair verbal learning, provoke acute psychosis, and increase the risk of schizophrenia. It is unclear where C sativa acts in the human brain to modulate verbal learning and to induce psychotic symptoms. Objectives: To investigate the effects of 2 main psychoactive constituents of C sativa, Delta 9-tetrahydrocannabinol (Delta 9-THC) and cannabidiol, on regional brain function during verbal paired associate learning. Design: Subjects were studied on 3 separate occasions using a block design functional magnetic resonance imaging paradigm while performing a verbal paired associate learning task. Each imaging session was preceded by the ingestion of Delta 9-THC (10 mg), cannabidiol (600 mg), or placebo in a double-blind, randomized, placebo-controlled, repeated-measures, within-subject design. Setting: University research center. Participants: Fifteen healthy, native English-speaking, right-handed men of white race/ethnicity who had used C sativa 15 times or less and had minimal exposure to other illicit drugs in their lifetime. Main Outcome Measures: Regional brain activation ( blood oxygen level-dependent response), performance in a verbal learning task, and objective and subjective ratings of psychotic symptoms, anxiety, intoxication, and sedation. Results: Delta 9-Tetrahydrocannabinol increased psychotic symptoms and levels of anxiety, intoxication, and sedation, whereas no significant effect was noted on these parameters following administration of cannabidiol. Performance in the verbal learning task was not significantly modulated by either drug. Administration of Delta 9-THC augmented activation in the parahippocampal gyrus during blocks 2 and 3 such that the normal linear decrement in activation across repeated encoding blocks was no longer evident. Delta 9-Tetrahydrocannabinol also attenuated the normal time-dependent change in ventrostriatal activation during retrieval of word pairs, which was directly correlated with concurrently induced psychotic symptoms. In contrast, administration of cannabidiol had no such effect. Conclusion: The modulation of mediotemporal and ventrostriatal function by Delta 9-THC may underlie the effects of C sativa on verbal learning and psychotic symptoms, respectively.

Conselhos locais de saúde : caminhos e (des)caminhos da participação social no Sistema Único de Saúde

A partir da descentralização, novas instâncias de negociação e novas alternativas de ordenamento da estrutura organizacional do Sistema Único de Saúde (SUS) foram criadas. Dentre estas alternativas, podemos citar os conselhos de saúde, importantes canais de participação social. Todavia, frente às limitações destes canais tradicionais de articulação entre Estado e sociedade, destacamos os ideais da gestão participativa e os Conselhos Locais de Saúde (CLS) como alternativa de renovação e criação de instâncias mais flexíveis, porosas e efetivas às complexas demandas sociais. Neste sentido, buscamos analisar o processo de criação e implementação dos CLS do município de Anchieta/ES, a partir de uma abordagem quali-quantativa. Inicialmente, traçamos o perfil socioeconômico e político dos conselheiros eleitos, a partir de um questionário aplicado a uma amostra de 54 conselheiros; dados que foram categorizados e analisados por meio do emprego de estatísticas descritivas. Em seguida, entrevistamos treze conselheiros, de dois conselhos distintos do município, procedendo à análise de conteúdo do material, a partir dos ideais de Bardin (2000). Os resultados demonstraram que os conselhos foram criados a partir da iniciativa da gestão municipal em 2011, e que simplesmente institucionalizá-los como espaço de participação social não foi suficiente para promover a mobilização social e o envolvimento comunitário. Quanto ao perfil dos conselheiros locais, 78% são mulheres, com predominância de raça/cor branca, idade entre os 20 e 39 anos e funcionárias públicas; 57% possuem Ensino Médio e participaram como conselheiro por dois anos, e 60% destes já tiveram outras experiências de participação similares aos CLS. Do material oriundo das entrevistas, emergiram quatro categorias de análise, a saber: 1) Ser ou não ser conselheiro de saúde? Eis a questão!; 2) O não pertencimento e a não-participação; 3) Conselhos Locais de Saúde: elos, meios e mediações; e 4) A exogenia da administração e os obstáculos à participação social. Os entraves ao funcionamento dos conselhos de saúde, mesmo em nível local, ainda são desafios a serem superados, para que estas instâncias sejam mais influentes na gestão pública, conforme os princípios de sua criação. A participação social e a democracia são fundamentais para a construção de políticas de saúde que correspondam às reais demandas da comunidade. Contudo, para garantir a democracia na sociedade não basta promover a descentralização. É necessário que os sujeitos políticos resistam às relações de dominação, opressão e subordinação. Para isso, torna-se imprescindível os programas de educação para cidadania dos sujeitos envolvidos nestes fóruns de participação. O que nos motiva, enfim, é notarmos a existência, entre os conselheiros eleitos, de sujeitos protagonistas de seu próprio devir; sujeitos que atuam como agentes transformadores, motivadores de sonhos e projetos em prol da saúde pública e de sua comunidade.

ECTOPIC CUTANEOUS SCHISTOSOMIASIS: REPORT OF TWO CASES AND A REVIEW OF THE LITERATURE

Two cases of ectopic cutaneous schistosomiasis are described. Both patients presented with abdominal papular skin lesions, which on biopsy were found to contain granulomas with Schistosoma mansoni eggs. Twenty-five other cases were retrieved from the literature. Most patients were female, mean age 24.9 year, with a predominance of the white race. The most common localization was anterior thorax and abdomen. Usually, the lesions were asymptomatic. In few cases, however, severe clinical syndromes due to the parasite coexisted, such as transverse myelitis or the acute-toxemic form of the disease. Intestinal infection was not frequently demonstrated in these patients. The importance of the recognition of these cutaneous lesions may rest on the opportunity to provide an etiological diagnosis in these difficult cases.

Incidence of hepatitis C in Brazil

Abstract INTRODUCTION: Hepatitis C is a public health problem of global dimensions, affecting approximately 200 million people worldwide. The main objective of this study was to estimate the incidence rate of hepatitis C in Brazil during the period between 2001 and 2012. METHODS: An epidemiological, temporal, and descriptive study was performed using data from the Information System for Reportable Diseases. RESULTS: Between 2001 and 2012, a total of 151,056 hepatitis C cases were recorded, accounting for 30.3% of all hepatitis notifications in Brazil. The average gross coefficient for the analysis period was 6.7 new cases per 100,000 inhabitants. The regions with the highest rates were the Southeast region (8.7 new cases/100,000 inhabitants) and the South (13.9 new cases/100,000 inhabitants). There was a predominance of men with respect to the incidence rate (8.0 new cases/100,000 inhabitants) compared to women (5.5 new cases/100,000 inhabitants). Injection drug use was the most common source of infection, and members of the white race, residents of urban areas, and those aged 60 to 64 years had the highest incidences. CONCLUSIONS: Over the last 10 years, the incidence of hepatitis C in Brazil has increased, mainly in the South and Southeast. The adoption of fast, accurate diagnostic methods, together with epidemiological awareness, can facilitate early intervention measures for adequate control of the disease.

Delayed diagnosis of HIV infection and late initiation of antiretroviral therapy in the Swiss HIV Cohort Study.

OBJECTIVES: To investigate delayed HIV diagnosis and late initiation of antiretroviral therapy (ART) in the Swiss HIV Cohort Study. METHODS: Two sub-populations were included: 1915 patients with HIV diagnosis from 1998 to 2007 and within 3 months of cohort registration (group A), and 1730 treatment-naïve patients with CD4>or=200 cells/microL before their second cohort visit (group B). In group A, predictors for low initial CD4 cell counts were examined with a median regression. In group B, we studied predictors for CD4<200 cells/microL without ART despite cohort follow-up. RESULTS: Median initial CD4 cell count in group A was 331 cells/microL; 31% and 10% were <200 and <50 cells/microL, respectively. Risk factors for low CD4 count were age and non-White race. Homosexual transmission, intravenous drug use and living alone were protective. In group B, 30% initiated ART with CD4>or=200 cells/microL; 18% and 2% dropped to CD4 <200 and <50 cells/microL without ART, respectively. Sub-Saharan origin was associated with lower probability of CD4 <200 cells/microL without ART during follow-up. Median CD4 count at ART initiation was 207 and 253 cells/microL in groups A and B, respectively. CONCLUSIONS: CD4<200 cells/microL and, particularly, CD4<50 cells/microL before starting ART are predominantly caused by late presentation. Earlier HIV diagnosis is paramount.

Prevalência de incontinência urinária e fatores associados em idosos institucionalizados

Urinary incontinence (UI) is a geriatric syndrome that is especially prevalent in institutionalized individuals, and that causes economic and social impacts derived from treatment costs and overload of caregiver. UI also entails physical consequences to the health of the elderly, such as urinary tract infections or pressure ulcers, among other health problems. However, the existing national research on this condition is still scarce and comprises serious methodological biases. Therefore, the objective of this study is to determine the prevalence of urinary incontinence and associated factors in institutionalized elderly. A cross-sectional study is presented herein, conducted between October and December, 2013 and carried out in 10 nursing homes in the city of Natal (Northeast Brazil). UI was verified through the program Minimum Data Set version 3.0, which was also used to assess fecal incontinence, urinary devices and UI control programs. Data collection included sociodemographic information, UI characterization, as well as variables related to the institution itself and to health conditions (comorbidities, medication, pelvic floor surgery, Barthel Index for functional capacity and Pfeiffer test for cognitive status). Bivariate analysis was performed using the Chi-Square Test (or Fisher‟s Exact Test) and the Linear Chi-Square Test, calculating the prevalence ratio with 95% confidence interval. Variables with p value under 0.20 were included in the multivariate analysis, which was performed using the Stepwise Forward logistic regression. The inclusion of variables in the final model depended on the likelihood ratio test, absence of multicollinearity and on the Hosmer-Lemeshow test. A statistical significance level of 0.05 was considered. Six (1.8%) hospitalized elderly, one individual in palliative care (0.3%) and one (0.3%) individual under the age of 60 were excluded from the study. The final sample consisted of 321 elderly, mostly females, with a mean age of 81.5 years. The prevalence of UI was 59.43% and the final model revealed statistically a significant association between UI and white race, physical inactivity, stroke, mobility constraints and cognitive decline. The most frequent UI type was functional UI due to physical or cognitive disability, and incontinence control measures were applied only to a minority of residents (approximately 8%). It is concluded that UI is a health issue that affects more than half of the institutionalized elderly, and is associated with white race, physical inactivity, stroke and other geriatric syndromes such as immobility and cognitive disability. Most of these associated factors are modifiable and therefore the findings of this study highlight the importance of UI prevention and treatment in nursing homes, which include general measures, such as physical and psychosocial activities, and specific measures, such as prompted voiding

Incidence and prevalence rates of inflammatory bowel diseases, in midwestern of São Paulo State, Brazil

CONTEXTO: No Brasil, a incidência e prevalência populacionais das doenças inflamatórias intestinais são desconhecidas. OBJETIVO: Neste trabalho, estimou-se esses parâmetros na área que abrange a antiga região de saúde DIR 11, no centro-oeste do Estado de São Paulo. MÉTODOS: Usou-se um registro sequencial de 115 pacientes (>15 anos de idade) com doenças inflamatórias intestinais, residindo na área de estudo, atendidos durante período de 20 anos (1986-2005) em hospital de referência. Estimou-se, para quatro períodos consecutivos de 5 anos, as incidências e prevalências de acordo com os tipos de doença e do sexo de doentes. As suas inter-relações foram analisadas utilizando o modelo de regressão linear de Poisson. RESULTADOS: Na região, as doenças inflamatórias intestinais foram predominantes em mulheres jovens, da raça branca, residindo na zona urbana.A incidência da retocolite foi maior que a da doença de Crohn e das colites não classificadas, e diferentemente dessas duas ultimas, mostrou decréscimo no último período (2001-2005). Neste mesmo período, a taxa da incidência para a retocolite foi de 4,48 casos/100.000 habitantes, para a doença de Crohn atingiu 3,50 casos/100.000 habitantes e a das colites não classificadas foi de 1,75 casos/100.000 habitantes. As prevalências atingiram os valores de 14,81 casos/100.000 habitantes para a retocolite, 5,65 casos/100.000 habitantes para a doenças de Crohn e 2,14 casos/100.000 habitantes. Considerando todas as doenças inflamatórias a prevalência atingiu o valor de 22,61 casos/100.000 habitantes. CONCLUSÃO:A incidência dessas doenças inflamatórias intestinais nessa região é baixa, igualando-se aos países da América Latina e do sul da Europa e sua crescente prevalência justifica políticas de saúde para as suas abordagens.
