Periurbanização da leishmaniose visceral e emergência da coinfecção HIV/leishimania, no Rio Grande do Norte

Visceral leishmaniasis (VL) has undergone changes in terms of clinical and epidemiological presentation worldwide. Urbanization has been described in different regions of Brazil and the world, as well as in the state of Rio Grande do Norte. These changes have impacted in the clinical outcome of Leishmania infection. A new clinical entity called co-infection of HIV/Leishmania has been described as a consequence of overlapping areas of occurrence of VL and HIV / AIDS in different countries including Brazil. The aim of this study was to define the process of periurbanization of the LV and describe a case series of co-infection HIV / Leishmania in Rio Grande do Norte. A new demographic pattern of VL was detected, with an increase in the number VL adult male subjects. Analysis of spatial distribution of VL in the state of Rio Grande do Norte showed that in the past 20 years VL tends to occur in larger cities and therefore the highest risk disease is greater in the eastern and western regions. The first region included Natal, the state capital, where the process of suburbanization began in 1990, and more recently the city of Mossoró, the second largest state, where periurbanization began in the last five years. In 1990, the emergence of co-infection HIV/Leishmania in the state was observed. Case-control study revealed that the new clinical entity affects adult males, who acquired HIV through sexual intercourse, 40% of those with a preivous history of leishmania infection Relapse and death from LV is increased in HIV positive compared with HIV-negative patients matched by sex and age. This pattern is similar to the observed in Europe, except of the route of transmission, where in Europe occured concomitantly, by parenteral route in drug users. Analysis of spatial distribution identified overlapping new areas of occurrence of HIV / AIDS and LV potentially signaling to increased risk of this new clinical entity as described above. Therefore, epidemiological surveillance for co-infection HIV / Leishmania should be adopted in all areas of risk of VL. At the same time, it is necessary to evaluate drug resistance currently used in the treatment of VL, as well as parenteral transmission of L infantum/ chagasi in areas where drug dependence is a risk factor for HIV acquisition

Aspectos morfológicos do fruto, da semente e desenvolvimento pós-seminal de faveira (Clitoria fairchildiana R. A. Howard. - Fabaceae)

O presente trabalho teve por objetivo descrever a morfologia dos frutos, das sementes e o desenvolvimento pós-seminal de faveira (Clitoria fairchildiana R. A. Howard. - Fabaceae). Os frutos e as sementes foram caracterizados quanto à forma e dimensões. Periodicamente, unidades representativas de cada fase de germinação foram retiradas para as descrições morfológicas. Os frutos são do tipo legume, deiscentes e de coloração marrom. As sementes são exalbuminosas, de forma orbicular e achatada, com tegumento de coloração castanho-esverdeada. O hilo tem forma elíptica, homocromo e de tamanho pequeno em relação à semente. Os cotilédones são livres, de coloração verde, maciços e plano-convexos e o embrião é invaginado. O início do desenvolvimento pós-seminal é marcado pelo rompimento do tegumento e emissão da raiz primária, glabra, de coloração amarelo-esverdeada e de forma cilíndrica. Posteriormente, observa-se o desenvolvimento das raízes secundárias, levemente esbranquiçadas, curtas e filiformes. em seguida, o crescimento do hipocótilo proporciona a emergência dos cotilédones e da plúmula acima do substrato. O epicótilo alonga-se e, em seguida, observa-se a expansão dos eófilos, simples, opostos, com tricomas simples e esparsos, pecíolos curtos com estípulas em sua base. Posteriormente ao desenvolvimento dos eófilos, ocorre a formação do segundo par de folhas, alternas, trifolioladas, estipuladas e com estipelas na base dos peciólulos.

A corretagem de imóveis no Rio Grande do Norte: das práticas históricas à emergência como segmento integrante da fração imobiliária do capital

This research proposed to question the development of what was defined as historical practices (commercial, social and political institutions), of the economic activity of the real estate brokerage in the Rio Grande do Norte from the progressive institutionalization of economic agents - individuals (realtors) and legal (real estate) - based on two main approaches: a) the development of economic activity as an integral segment of a fraction of capital (POULANTZAs, 1985; LESSA, 1981). This work set out from a socio-historical approach of the historical practices development the of real estate brokerage in Brazil started in the Southeast, especially in the cities of Rio de Janeiro and São Paulo as a result of the "expansion of capitalist relations by the housing sector" (RIBEIRO , 1996). especially the real estate capital ; b) the historical development of relations between labor and capital within the activity, in other words, the development of the relationship between realtors and Real Estate in relation to "group of interests" and their "collective actions" (OFFE, 1984). These historical practices are defined in this research as: 1) mercantile practices, times when there was no distinction between the activity of real estate brokerage and other forms of mercantile capital; 2) social practices, which began in the 1930s, when agents of real estate are to be distinguished from each other within the activity through Taylorist division of labor between workers realtors and developers of real estate; 3) political and institutional practices, initiated in 1962, characterized by State action, in the individualization and distinction of the agents of real estate brokerage as socioprofessional category regulated throughout Brazil by Law 4.116/62 and 6.530/78. The results achieved by the present study showed that in Rio Grande do Norte, due to the specifics as to the peripheral processes of urbanization of the constitution of the land market, as well as the process of conservative modernization of the oligarchic State from the 1960s (CLEMENTINE, 1995; FERREIRA, 1996, 2010, TRINDADE, 2004), the State was led to the development of a late manifestation of the historical practices of real estate brokerage. In other words, it was a process in which historical practices, in particular social practices, not fully developed, mitigating, thus the perception of realtors from his position in the process of exploitation of labor by the Real Estate. And, as a result, of their collective interests front of them.

Caracterização do acidente de trânsito e gravidade do trauma: um estudo em vítimas de um hospital de emergência de Natal

Descriptive exploratory study, with quantitative approach and prospective data performed on the Monsenhor Walfredo Gurgel Hospital Complex (MWGH), in Natal/RN, aiming to classify the type of motor vehicle involved in the accident, the public roadway s user quality and the more frequent injuries; to evaluate the severity of trauma in traffic accident victims; characterized the severity of the injuries and the trauma, and the type of motor vehicle involved. The population comprises 605 traffic accident victims, with data collected between October and December 2007. We used as a support for the evaluation of severity of injuries and trauma the Glasgow Coma Scale (GCSl), the Condensed Abbreviated Injury Scale (CAIS) and the Injury Severity Score (ISS). The results show that 82.8% of the victims were male; 78.4% were aged 18 to 38; the victims originating from the State s Countryside prevailed (43.1%); 24.3% of the population had completed middle-level instruction; 23.1% worked on commerce and auxiliary activities; most (79.4%) was catholic; 48.8% were married/consensual union; 76.2% earned up to two monthly minimum wages; Sunday was the day with the most accidents (25.1%); 47.4% were attended to in under an hour after the event; the motorcycle on its own was responsible for 53.2% of the accidents; 42.3% were attended to by the SAMU; 61.8% were victims of crashes; over half (53.4%) used individual protection equipment (IPE); 49.4% were helmets and 4.0% the seatbelt; 61.3% were motorcycle drivers; 43.3% of the accidents took place in the afternoon shift; from 395 drivers, 55.2% were licensed, and 50.7% among those had been licensed for 1 to 5 years; 90.7% of the victims had GCS1 between 13 and 15 points at the time of evaluation; the body area most affected was the external surface (35.9%); 38.8% of the injuries were light or moderate (AIS=1 and AIS=2); 83.2% had light trauma (ISS between 1 and 15 points). In face of the results, we can conclude that there is a risk for the elevation of injury severity and trauma resulting from traffic accidents, when these events are related to certain variables such as gender, age, weekday, the interval between the accident and the first care, ingestion of drugs, type of accident, the public roadway s user quality, the use of IPE, day shift, body regions and the type of motor vehicle involved in the accident

Estádios de colheita e repouso pós-colheita dos frutos na qualidade de sementes de mamoneira

O presente trabalho teve como objetivo avaliar o efeito dos estádios de colheita e do repouso pós-colheita dos frutos na qualidade de sementes de mamoneira (Ricinus communis L.) cultivar AL Guarany 2002. Foram avaliadas 9 épocas de colheita dos racemos, dos 30 até 142 dias após a antese (DAA), em intervalos de 14 dias e quatro condições de repouso: sem e com repouso de sete dias de sementes extraídas (nuas), de frutos e de frutos presos ao racemo. Foram avaliados a cor de frutos e de sementes; o teor de água, a massa seca, as porcentagens de germinação e de vigor das sementes (primeira contagem de germinação, índice de velocidade de emergência e condutividade elétrica). Sementes com máxima qualidade fisiológica e massa seca foram obtidas de frutos colhidos aos 86 DAA. A colheita pode ser realizada até os 128 DAA sem redução da germinação, mas com prejuízos devido à queda dos frutos, dispersão das sementes aos 100 dias e reduções do vigor. O repouso permitiu a antecipação da colheita para 72 DAA sem prejuízos à germinação e massa seca, mas com reduções de vigor. A cor dos frutos, das sementes e o teor de água das sementes são parâmetros eficientes para a identificação do ponto de colheita, principalmente se usados conjuntamente.

Da emergência da personagem social do homosexual à cultura gay: uma leitura a partir de Michel Foucault

This present research aims to understand the concept of homosexuality as a social creation that comes permeated by the discourses of sexuality devices. It discusses the issue of homosexuality with a focus on works of Michel Foucault, in special The History of Sexuality, where the author emphasizes that homosexuality as a social construct that manifests itself during the nineteenth century. From the Foucauldian discourse, it is proposed to understand and analyze the creation of the concept of homosexuality, which is built around the subordination of the individual as a social agent, or the creation of homosexuality does not refer to sexual intercourse between individuals of the same sex, but a social subject and the position it takes in society. So along with the birth of the homosexual individual, there is also the construction of the individual as a social subject, as being, homosexuality and homosexual subject are products of overlapping powerculture. When addressing this theme, it breaks the hegemony that seeks to characterize naturalized of sexuality and, consequently, homosexuality, born with the original speeches on medical and psychiatric couches, in which one perceives the role of power in the discourses deploying the truths aimed at sexuality. With this, there has been an argument that seeks to refute the eugenics that includes sexuality as something natural, instituting a homosexual as a guy born hostage to a bad genetic and abnormal who should be treated for their disease, and understand this individual as a product of social discourse

O médico diante da morte na urgência e emergência:reflexões sobre o ser médico

The literature pointed that the way which people deal with death have been changing along centuries, and nowadays what is realized it is that, each time more, the human being have difficulties to deal with death. Due to the fact that the main function of the physician is to save their patients lives; responsibility that is aggravated by the necessity of to take decisions quickly, once he need to deal with the unexpected situations of the urgency and emergency, many times these professional have to face of impotency and fail situations, when he lose a patient. The main goal of this study was to understand the experience of physicians that work in the urgency and emergency, in front of death. These questioning it justified by the fact of the physicians do not have, many times, a space to express their suffering and anguish about the issues related to death in their work routine, despite lifedeath question to be often present their everyday. It is still possible to verify in the literature, an appointment of the necessity of to include in the curriculum of Medicine courses, subjects that approach such questions. The method used was based on the existential-phenomenological perspective, using as instrument the participant observation, to the intent of understand the routine in the urgency and emergency context, and semi-structured interview. It was interviewed six physicians that work in the urgency and emergency of the most important hospital of public health system of Natal-RN. The results showed that the physicians reported pleasure in work in the urgency and emergency, despite of they presented stress and the difficulties that they deal with in the public system. Despite of the fact that the death to be considered as a phenomenon that make part of the physician s routine, sometimes, deals with these one is more difficult. Many times losses generate an impotency and guilty feeling, as well as questionings about their performance during the attempts to save lives. We verified, from this study, the importance of the existence of some kind of intervention in the emergency, in order to the physicians can elaborate the questions about death and die emerged in their work. We consider yet that this study corroborates and reiterates the discussions concerning the importance of this thematic to be approached in a more effective way, during the academic formation of these professionals, as well as, the importance of a larger investment from the part of Government in the urgency and emergency sector, in order to propitiate to these professionals a work that brings less harmful for their health

Efeito de pós vegetais sobre Sitophilus zeamais (Mots., 1855) (Coleoptera: Curculionidae)

Objetivou-se testar a atividade inseticida de pós vegetais em Sitophilus zeamais. Foram testados os pós de Anadenanthera colubrina (folhas); Annona muricata (sementes); Azadirachta inidica (folhas e flores); Caesalpinia pyramidalis (folhas), Chenopodium ambrosioides (folhas e flores); Cymbopogon sp. (folhas); Cymbopogon citratus (folhas); Momordica charantia (folhas e frutos); Piper nigrum (sementes); e Ricinus communis (folhas). Além disso, avaliou-se o potencial inseticida de folhas e flores de C. ambrosioides em diferentes dosagens. Na avaliação de repelência foi estabelecido um índice de preferência, e utilizado o teste t para comparação das médias das espécies vegetais. Também foi realizada a comparação das médias das plantas que foram classificadas como repelentes. Para avaliação da mortalidade, procedeu-se a análise de variância e a comparação das médias pelo teste de Tukey e também o teste t para comparação das médias dos tratamentos C. ambrosioides e P. nigrum. Os dados de emergência foram analisados pelo teste de Tukey. Para avaliar os dados de mortalidade, ocasionados por C. ambrosioides, determinou-se a CL50 utilizando a análise de Probit. Os dados de emergência foram verificados pela análise de regressão. As plantas que provocaram repelência foram Cymbopogon sp., C. citratus e C. ambrosioides. A planta que mais afetou a sobrevivência da praga foi C. ambrosioides, que provocou mortalidade total dos insetos infestantes e nenhuma emergência. Adultos de S. zeamais são mais suscetíveis a concentração de 0,125 g do pó de C. ambrosioides.

Caracterização morfológica do fruto, da semente e desenvolvimento pós-seminal do abacateiro

A propagação do abacateiro é comercialmente, realizada por enxertia da variedade desejada sobre porta-enxertos seminais. No entanto, a literatura é discordante sobre a ocorrência de poliembrionia e tipo de fruto, nesta espécie. Em função do exposto, o trabalho objetivou caracterizar o tipo de fruto, aspectos morfológicos da semente e da plântula, além de avaliar o número de embriões existente. O abacateiro possui frutos do tipo baga, as sementes são monoembriônicas e exalbuminosas, a germinação é hipógea e a emergência das plântulas ocorreu 33 dias após a semeadura. A raiz primária é longa e de coloração branca e as raízes secundárias são curtas e filiformes. Os cotilédones são maciços e de coloração rosada. Foi possível observar a presença de múltiplos caulículos na semente de abacate, originados do colo. As sementes apresentam policaulia; o início da estabilização da emergência de plântulas ocorreu na oitava semana, sendo inviável para a propagação da espécie, manter essas sementes no viveiro por mais tempo.
