O corpo na interpretação musical

Esta comunicação será dividida em duas partes: na primeira parte e feita a abordagem teórica sobre questões relacionadas com o corpo enquanto responsável pelos aspectos mecânicos e expressivos da interpretação; na segunda parte são apresentadas demonstrações práticas e sua avaliação sob um ponto de vista empírico. A apresentação teórica tem como base um trabalho da autora, intitulado "The Body in Musical Performance", que analisa o comportamento corpor.al desde a percepção musical pré-natal e ao longo das várias fases de crescimento, até às subtis interacções não verbais entre intérpretes de um mesmo grupo e destes com o público. As demonstrações práticas abordarão o seguinte: - gestualidade, expressão corporal e expressividad.e não verbal no pianista solista e seu significado; - a comunicação e expressividade corporal entre membros de um quarteto de cordas desde o ensaio até à apresentação pública.

Diferenças de gênero no campo da sexologia: novos contextos e velhas definições

OBJETIVO: Analisar concepções de gênero e sexualidade presentes no campo de intervenções terapêuticas em torno do sexo. PROCEDIMENTOS METODOLÓGICOS: Observação etnográfica, complementada por análise documental de material impresso referente ao X Congresso Brasileiro de Sexualidade Humana, promovido pela Sociedade Brasileira de Estudos em Sexualidade Humana, e ao VIII Congresso Brasileiro sobre Inadequações Sexuais, promovido pela Associação Brasileira para o Estudo das Inadequações Sexuais, realizados em 2005. A análise privilegiou a interação entre a perspectiva quantitativa no processamento das variáveis profissão e gênero dos participantes e temas das palestras, e perspectiva qualitativa na análise e interpretação do conjunto mais geral de dados. RESULTADOS: Os temas das sessões e o enfoque das apresentações sugerem que o campo é definido pelo contraste entre duas especialidades médicas: a ginecologia e a urologia, a primeira voltada para disfunções femininas e do casal e a segunda para as disfunções masculinas. CONCLUSÕES: A sexualidade masculina é abordada por perspectiva predominantemente biomédica, centrada na fisiologia da ereção e na prescrição de medicamentos, enquanto a sexualidade feminina é apresentada como condicionada por problemas relacionais, mais adequados à intervenção psicológica.

Principal components and generalized linear modeling in the correlation between hospital admissions and air pollution

OBJECTIVE To analyze the association between concentrations of air pollutants and admissions for respiratory causes in children. METHODS Ecological time series study. Daily figures for hospital admissions of children aged < 6, and daily concentrations of air pollutants (PM10, SO2, NO2, O3 and CO) were analyzed in the Região da Grande Vitória, ES, Southeastern Brazil, from January 2005 to December 2010. For statistical analysis, two techniques were combined: Poisson regression with generalized additive models and principal model component analysis. Those analysis techniques complemented each other and provided more significant estimates in the estimation of relative risk. The models were adjusted for temporal trend, seasonality, day of the week, meteorological factors and autocorrelation. In the final adjustment of the model, it was necessary to include models of the Autoregressive Moving Average Models (p, q) type in the residuals in order to eliminate the autocorrelation structures present in the components. RESULTS For every 10:49 μg/m3 increase (interquartile range) in levels of the pollutant PM10 there was a 3.0% increase in the relative risk estimated using the generalized additive model analysis of main components-seasonal autoregressive – while in the usual generalized additive model, the estimate was 2.0%. CONCLUSIONS Compared to the usual generalized additive model, in general, the proposed aspect of generalized additive model − principal component analysis, showed better results in estimating relative risk and quality of fit.

Intimate partner violence after the diagnosis of sexually transmitted diseases

OBJECTIVE To assess the prevalence and factors associated with intimate partner violence after the diagnosis of sexually transmitted diseases.METHODS This cross-sectional study was conducted in Fortaleza, CE, Northeastern Brazil, in 2012 and involved 221 individuals (40.3% male and 59.7% female) attended to at reference health care units for the treatment of sexually transmitted diseases. Data were collected using a questionnaire applied during interviews with each participant. A multivariate analysis with a logistic regression model was conducted using the stepwise technique. Only the variables with a p value < 0.05 were included in the adjusted analysis. The odds ratio (OR) with 95% confidence interval (CI) was used as the measure of effect.RESULTS A total of 30.3% of the participants reported experiencing some type of violence (27.6%, psychological; 5.9%, physical; and 7.2%, sexual) after the diagnosis of sexually transmitted disease. In the multivariate analysis adjusted to assess intimate partner violence after the revelation of the diagnosis of sexually transmitted diseases, the following variables remained statistically significant: extramarital relations (OR = 3.72; 95%CI 1.91;7.26; p = 0.000), alcohol consumption by the partner (OR = 2.16; 95%CI 1.08;4.33; p = 0.026), history of violence prior to diagnosis (OR = 2.87; 95%CI 1.44;5.69; p = 0.003), and fear of disclosing the diagnosis to the partner (OR = 2.66; 95%CI 1.32;5.32; p = 0.006).CONCLUSIONS Individuals who had extramarital relations, experienced violence prior to the diagnosis of sexually transmitted disease, feared disclosing the diagnosis to the partner, and those whose partner consumed alcohol had an increased likelihood of suffering violence. The high prevalence of intimate partner violence suggests that this population is vulnerable and therefore intervention efforts should be directed to them. Referral health care services for the treatment of sexually transmitted diseases can be strategic places to identify and prevent intimate partner violence.

Factors associated with dietary supplement use by people who exercise at gyms

OBJECTIVE To assess the factors associated with the use of dietary supplements by people who exercise at gyms.METHODS A cross-sectional study with a sample defined by convenience, considering the number of gyms registered in the Conselho Regional de Educação Física (Regional Council of Physical Education) of Sao Luis, MA, Northeastern Brazil, from July 2011 to July 2012. The final sample comprised 723 individuals who exercise at gyms. The dependent variable was supplement use, and the explanatory variables were length of time and motivation of the physical exercises, duration, goal and self-perception of training, weekly frequency of gym attendance, sex, age, educational attainment, self-perception of body weight, smoking and self-perception of diet. The association between variables was analysed by hierarchical Poisson regression based on a theoretical model.RESULTS Supplement use was reported by 64.7% of the participants. Most of the sample was male (52.6%). The most frequent age group was 20 to 39 years (74.4%). Most participants (46.1%) had been exercising for over a year. The following variables were associated with supplement use: self-perceiving body weight as below ideal (p < 0.001), smoking (p < 0.001), exercising for 7 to 12 months (p = 0.028) or more than one year (p < 0.001), spending more than two hours at the gym (p = 0.051), and perceiving training as moderate (p = 0.024) or intense (p = 0.001).CONCLUSIONS The use of supplements lacks proper professional guidance, being motivated by individuals unsatisfied with their low body weight and who perceive their workout as intense, which raises the need for monitoring this population.

Tratamento da esquistossomose mansônica hepatesplênica com praziquantel

Noventa e quatro pacientes, 22 do sexo masculino e 72 do feminino, com idades variando de 11 a 71 anos, média de 25, apresentando a forma hepatesplênica da esquistossomose mansônica, foram tratados com uma nova droga antiesquistossomótica — praziquantel — objetivando-se investigar sua eficácia e tolerância. Duas doses orais — 1 x 30 e 2 x 25 mg/kg — foram comparadas. Efeitos colaterais foram verificados durante os primeiros dois dias seguintes à administração da droga, mas usualmente de média intensidade e curta duração. Os mais freqüentes e, por vezes, mais severos foram: dor ou desconforto abdominal, diarréia, tontura, cefaléia e náusea. Febre esteve presente em 19,2% dos casos e urticaria e prurido em dois pacientes. A investigação laboratorial mostrou, em alguns casos, ligeiras alterações enzimáticas (AST, ALT, γ-GT) 24 horas após a medicação. Nenhuma modificação da urinálise, da glicose sangüínea e dos dados hematológicos foi detectada, exceto o aumento comumente observado dos eosinófilos nos 7." e 30.° dias, relacionado à morte dos parasitas dentro do organismo. Da mesma forma, nenhuma anormalidade foi verificada no estudo eletroencefalográfico. Na eletrocardiografia, observou-se, em duas pacientes, uma ligeira e transitória alteração na repolarização ventricular. No que diz respeito à cura parasitológica, constatou-se, em 62 pacientes que concluíram seis meses de controle, um porcentual global de cura de 80,6%, sendo de 76,7% com a dose de 30 mg/lkg e de 84,4% com a de 2 x 25 mg/kg. Os pacientes não curados tiveram, por outro lado, uma acentuada redução no número de ovos do S. mansoni eliminados nas fezes. Além disso, cinco pacientes não curados, foram retratados seis ou mais meses depois, com a mesma dose inicial, obtendo-se 100°/o de negatividade nos exames de fezes. Os Autores acreditam que com a administração de doses um pouco mais altas como, por exemplo, 60 mg/kg, se possa obter um maior porcentual de cura, sem prejuízo da boa tolerância. A melhora clínica e laboratorial a longo prazo, isto é, seis ou mais meses após a medicação, foi marcante em todos os parâmetros estudados.

Comprometimento pulmonar na malária (revisão)

Com uma incidência de 3 a 10% dos casos e letalidade próxima a 70%, o comprometimento pulmonar constitui uma das manifestações mais graves da malária por Plasmodium falciparum. Embora sua patogênese não esteja perfeitamente esclarecida, reconhece-se que a hiperativação do sistema imune por antígenos liberados pelo Plasmodium falciparum desempenhe um importante papel no desencadeamento e agravamento das lesões. A estrutura alvo parece ser o endotélio capilar, responsável pelo fluxo de líquidos para o espaço intersticial. Essas células são ativadas por ação de citocinas, produzidas por linfócitos e macrófagos durante a resposta imune, e passam a expressar em sua membrana celular receptores e moléculas de aderência que facilitam a sequestração de eritrócitos parasitados e também a aderência de células capazes de produzir mediadores inflamatórios. A reação inflamatória e a lesão endotelial que se seguem, juntamente com as alterações hemodinâmicas induzidas pelo bloqueio capilar devido ao acúmulo local de eritrócitos e células inflamatórias causam alterações de permeabilidade vascular e, consequentemente, acúmulo de líquido nos espaços intersticiais e alvéolos. Nos casos mais graves, as manifestações clínicas assemelham-se às do quadro da Síndrome do desconforto respiratório do adulto. Comprometimento pulmonar grave pode se instalar rapidamente em qualquer estágio da evolução clínica da malária, mesmo após a cura parasitológica, desconhecendo-se os fatores desencadeantes. Hiperparasitismo, insuficiência renal e gravidez constituem fatores predisponentes. O prognóstico dependerá da rapidez com que o diagnóstico for estabelecido e o correto tratamento instituído. Além do tratamento instituído contra o parasita, especial atenção deverá ser dispensada à monitorização hemodinâmica, se possível através de cateter de Swan-Ganz, à manutenção de adequada oxigenação e balanço hídrico, e ao controle de outras complicações, frequentemente associadas ao comprometimento pulmonar. O esclarecimento da patogenia do comprometimento pulmonar associado à malária deverá concorrer para a racionalização da conduta terapêutica e, consequentemente, melhorar o prognóstico dos indivíduos acometidos por esta complicação

Development of Secondary Resistance to Fluconazole in Cryptococcus neoformans Isolated from a Patient with AIDS

Cryptococcus neoformans is the fifth most common opportunistic agent of infection in patients with AIDS in the USA, exceeded only by Candida species, Pneumocystis carinii, cytomegalovirus and Mycobacterium avium1, 2, 6, 10, 11. In Brazil is the sixth, exceeded by Candida species, P. carinii, Mycobacterium species, Toxoplasma gondii, and herpes simplex virus (AIDS, Boletim Epidemiológico, set/nov 96, Ministério da Saúde, Brasil). During 30 years, the treatment of C. neoformans meningitis was based on the use of amphotericin B with or without flucytosine13. Nowadays, with the immunodepression caused by human immunodeficiency virus (HIV) infection and the availability of new antifungal drugs as the triazoles, the concept related to cure and relapses of cryptococcosis has been altered7, 20. Patients are treated with amphotericin B with or without flucytosine as initial therapy, but maintenance therapy is always necessary in AIDS patients with C. neoformans infections

Anti-phenolic glycolipid-I (PGL-I) determination using blood collection on filter paper in leprosy patients

The authors studied 70 leprosy patients and 20 normal individuals, comparing the traditional sera collection method and the finger prick blood with the conservation on filter paper for specific antibodies against the native phenolic glycolipid-I (PGL-I) from Mycobacterium leprae. The finger prick blood dried on filter paper was eluated in phosphate buffer saline (PBS) containing 0.5% gelatin. The classical method for native PGL-I was performed for these eluates, and compared with the antibody determination for sera. It was observed that there is a straight correlation comparing these two methods; although the titles found for the eluates were lower than those obtained for serology. This blood collection method could be useful for investigation of new leprosy cases in field, specially in contacts individuals.

Three year seroepidemiological study of varicella-zoster virus in São Paulo, Brazil

A serosurvey of varicella has been carried out in children attending the public school network of São Paulo city, Brazil, from 1992 to 1994. This study was performed in order to establish the age related prevalence of antibodies against varicella-zoster virus (VZV) and its age specific transmission dynamics pattern in these children. Among 2500 schools in the city of São Paulo public network, 304 were randomly selected; 7 children of a given age (ranging from 1 to 15 years) were randomly selected in each school, and blood samples were obtained by fingerprick into filter paper. Blood eluates were analyzed for the presence of antibodies to VZV by ELISA. Proportion of seropositivity were calculated for each age group. Samples consisted of 1768 individuals in 1992, 1758 in 1993, and 1817 in 1994, resulting in 5343 eluates. A high proportion of seropositive children from 1 to 3 years of age was observed, ascending until 10 years of age and reaching a plateau around 90% afterwards. VZV transmission in this community was similar along the three years of the study. In children attending public schools in the city of São Paulo, contact with VZV occurs in early childhood. If immunization against VZV is considered it should be introduced as soon as possible.

In vitro susceptibility to antifungal agents of clinical and environmental Cryptococcus neoformans isolated in Southern of Brazil

The purpose of the present study was to compare the susceptibility to four antifungal agents of 69 Cryptococcus neoformans strains isolated from AIDS patients with that of 13 C. neoformans strains isolated from the environment. Based on the NCCLS M27-A methodology the Minimal Inhibitory Concentrations (MICs) obtained for amphotericin B, itraconazole and ketoconazole were very similar for clinical and environmental isolates. Clinical isolates were less susceptible to fluconazole than environmental isolates. The significance of these findings and aspects concerning the importance, role and difficulties of C. neoformans susceptibility testing are also discussed.

Adult T-cell leukemia/lymphoma associated with HTLV-1 infection in a Brazilian adolescent

We present the case of a 15-year-old patient infected with HTLV-1 who developed a cutaneous T-cell lymphoma, confirmed by histopathological and immunohistochemical examination, as well as clinically and hematologically confirmed leukemia. The patient died 3 months after initial presentation of the disease. The rarity of the disease in this age group justifies the present report.

On the possibility of autochthonous Chagas disease in Roraima, Amazon region, Brazil, 2000-2001

Chagas disease has been almost entirely eradicated from the arid zones in Central and Northeastern Brazil where rare or no autochthonous cases have been reported. However, in the last 10 years the disease has increasingly been registered in the Amazon Region. Aiming to investigate the possibility of the occurrence of autochthonous cycle of Chagas disease in Roraima, triatomine collections, vectorial susceptibility studies (this one to be shown elsewhere), parasitological and serological analyses were conducted in three agricultural settlement areas (Rorainópolis, Passarão Project and Ilha Community). Blood-donor candidates were also investigated. This is the first epidemiological survey on Chagas disease conducted in agricultural settlements in Roraima. Triatomine species found were Triatoma maculata, Rhodnius pictipes, Rhodnius robustus and Panstrongylus geniculatus. Trypanosoma cruzi detection analyses included xenodiagnosis, indirect immunofluorescence, indirect hemaglutination, ELISA and kinetoplast PCR amplification. Natural triatomine infection was not found in intestinal contents. Twenty-five adult settlers (1.4% out of 1821, all > 15 year-old, 20 migrants) presented anti-T. cruzi antibodies. Two migrant settlers (from Minas Gerais and Maranhão) tested positive for more than two serological tests, besides either being positive for xenodiagnosis or PCR. Results show that Chagas disease is not endemic in the areas studied. However, all elements of the transmission cycle are present, demanding for an adequate and continuous vigilance.

A Triatoma maculata (Hemiptera, Reduviidae, Triatominae) population from Roraima, Amazon region, Brazil, has some bionomic characteristics of a potential Chagas disease vector

Even though Chagas disease is rare in the Brazilian Amazon, the conditions for the establishment of domiciliated cycles prevail in many areas where triatomines are of frequent occurrence. In Roraima, a previous serological and entomological survey in three agricultural settlements showed the existence of all transmission cycle elements, i.e., individuals infected by Trypanosoma cruzi, triatomine species previously found harboring T. cruzi in the broader Amazon region of neighboring countries and, domicile/ peridomicile conditions favorable to triatomine colonization. Triatoma maculata was the most frequent species, found in chicken houses in the peridomicile and sporadically within residences. Aiming to investigate the possibility of T. maculata to possess the potentiality to transmit T. cruzi in the area, bionomic characteristics were studied under laboratory conditions. These were feeding frequency, time for defecation after a blood meal, time elapsed in voluntary fasting pre- and pos-ecdysis, moulting time periods, pre-oviposition and oviposition periods and index of oviposition, incubation period, egg viability, longevity and mortality rate. Results show that the Passarão population of T. maculata should be considered a potential vector of T. cruzi since it shows a capacity to infest artificial ecotopes in the peridomicile, to carry out large number of meals during the nymphal cycle, to have a relatively short developmental cycle capable of producing 2.9 generations/year, to blood source eclecticism, to defecate immediately after the blood meal while still on the host and to the fact that has been previously found naturally infected by T.cruzi.
