Vertigo e o sublime trágico

Este é um artigo sobre a cinemática como espetáculo e a construção do sublime. Ocupa-se das construções engendradas do desejo e, no caso, interpreta o objeto de desejo como um objeto sublime. Ao mesmo tempo, é um artigo sobre decadência e abandono. Assim, este escrito tenta lidar com alguns conceitos imbuídos no relacionamento entre decadência e mortificação. Dessa forma, o artigo é sobre distância e sobre movimento, sobre Kinema (movimento grego) e a distância que é descrita pela queda da construção sublime e a melancolia associada a isso. Essas idéias são exploradas por intermédio do exame de um dos mais poderosos filmes de Alfred Hitchcock, Vertigo (1958), e uma noção de sublime trágico. Analisados conjuntamente, o conceito de sublime e a narrativa do filme provêem insights sobre a melancolia das representações que são úteis na perseguição obsessivo-compulsiva da idealização organizacional.

Expedições coloniais de coleta e a busca por oportunidades no sertão amazônico, c. 1750-1800

O artigo analisa a participação dos indígenas nas atividades de coleta das drogas do sertão, durante a vigência do Diretório dos Índios. Ele sugere uma explicação para os casos de participação voluntária naquelas expedições: nelas os indígenas encontravam espaço para ação independente, fomentavam a expansão de redes sociais e configuravam perspectivas econômicas.

Use of the Brazilian People’s Pharmacy Program by older adults

ABSTRACT OBJECTIVE To assess the prevalence and factors associated with the use of the expanded Brazilian People’s Pharmacy Program among older adults and the reasons for not using it. METHODS In this population-based cross-sectional study conducted in the urban area of Pelotas, RS, Southern Brazil, we evaluated 1,305 older adults (aged 60 years or over) who had used medication in the last 15 days. Independent variables were socioeconomic factors, economic status, household income in minimum wages, educational attainment in years of schooling and occupational status. Demographic variables were sex, age, marital status, and self-reported skin color/race. Poisson regression was employed to analyze the factors associated with the use of the program. RESULTS The prevalence of use was 57.0% whilst the prevalence of knowledge of the program was 87.0%. In individuals aged 80 years or over, use of the program was 41.0%. As to the origin of the prescriptions used by older adults, 46.0% were from the Brazilian Unified Health System. The main reasons for not using the program were: difficulty in getting prescriptions, medication shortage, and ignorance about the medications offered and about the program. Higher age, lower income, presence of chronic diseases, and use of four or more medications were associated with use of the program. CONCLUSIONS It is necessary to expand the knowledge and use of the Brazilian People’s Pharmacy Program, especially among older adults, and to improve the dissemination of its list of medications to users and physicians. Thus it will be possible to reduce spending on long-term medications, which are especially important for this population.

Host genetic and epigenetic factors in toxoplasmosis

Analysing human genetic variation provides a powerful tool in understanding risk factors for disease. Toxoplasma gondii acquired by the mother can be transmitted to the fetus. Infants with the most severe clinical signs in brain and eye are those infected early in pregnancy when fetal immunity is least well developed. Genetic analysis could provide unique insight into events in utero that are otherwise difficult to determine. We tested the hypothesis that propensity for T. gondii to cause eye disease is associated with genes previously implicated in congenital or juvenile onset ocular disease. Using mother-child pairs from Europe (EMSCOT) and child/parent trios from North America (NCCCTS), we demonstrated that ocular and brain disease in congenital toxoplasmosis associate with polymorphisms in ABCA4 encoding ATP-binding cassette transporter, subfamily A, member 4 previously associated with juvenile onset retinal dystrophies including Stargardt's disease. Polymorphisms at COL2A1 encoding type II collagen, previously associated with Stickler syndrome, associated only with ocular disease in congenital toxoplasmosis. Experimental studies showed that both ABCA4 and COL2A1 show isoform-specific epigenetic modifications consistent with imprinting, which provided an explanation for the patterns of inheritance observed. These genetic and epigenetic risk factors provide unique insight into molecular pathways in the pathogenesis of disease.
