O Serviço social nas organizações não-governamentais: tendências e particularidades

The present study is about the professional exercise of the Social Worker in ONGs associated with the ABONG in Natal city, state of Rio Grande do Norte, referring to the work conditions, claims and professional responses in front of the capital restructuration circumstances. The group of socio-historical transformations, as a result of the after-1970 dynamic capitalism, conducts a process of new configurations in the relationship between State and society that directly affect the social question nowadays, destroying social rights historically conquered for the workers. In this context, the ONGs assume a strategical social function of the social question, contributing with the change of responsibilities with the social from the State to the third sector. This social movement causes changes to the Social Work since this is one of the professions that act on the immediate expressions of the social question. After a qualitative research based on a theoricalmethodological critical and dialectical perspective, it was possible to discover some contradictions, details and tendencies of the professional exercise of the Social Worker in ONGs. Summarizing, the results of the research show that: a) it was detected a tendency of precarization, instability, insecurity, no-articulation, no-profissionalization of the professionals in the work conditions; b) demands are associated with a moment of the capital re-ordering, where new professional exigencies and responsibilities are related with capital necessities in the period of structural crisis; c) limits and contradictions are present in a professional daily work mainly in function of the characteristics of gestation and functioning of the ONGs; d) the professionals that were interviewed show significant difficulties in a articulation between the professional daily work in organizations and the totality of the social processes, limiting the capability of doing critics to the requisitions imposed by the capital

Eletromanometria do esfíncter superior do esôfago antes e após perfusão esofágica com ácido clorídrico 0,1N: estudo experimental no cão

Racional — A resposta do esfíncter esofágico superior ao refluxo gastroesofágico é controvertida. A perfusão esofágica com ácido clorídrico é modelo de estudo da ação do ácido o componente mais agressivo do refluxo sobre o esfíncter. Objetivos - Estudar o efeito da acidificação esofágica sobre o esfíncter esofágico superior através da eletromanometria esofágica. - Material e Métodos - em 30 cães adultos de ambos os sexos foram registrados estudos eletromanométricos do esôfago. A técnica utilizada foi a de puxada intermitente da sonda e perfusão contínua dos cateteres com água destilada. Estes exames permitiram as medidas da amplitude da pressão (mm Hg) e do comprimento (cm) do esfíncter superior do esôfago em condições basais (momento 1). Após esta fase, os animais foram submetidos a perfusão esofágica e divididos em 3 grupos de 10, na dependência da solução utilizada na perfusão e do momento do estudo: Grupo 1: perfusão esofágica com água destilada e estudos eletromanométricos realizados aos 15 minutos (momento 2) e 30 minutos (momento 3) do término da perfusão; Grupo 2: perfusão esofágica com HCl 0,1 N e estudos eletromanométricos realizados 15 minutos após o término da perfusão (momento 2); Grupo 3: perfusão esofágica com HCl 0,1 N e estudos eletromanométricos realizados 30 minutos após o término da perfusão (momento 3). Resultados/Conclusão - Os resultados observados permitiram concluir que a acidificação do esôfago não provocou alterações significativas sobre a amplitude de pressão e comprimento do esfíncter superior do esôfago.

Efeito do ácido zoledrônico em tíbias de ratas ooforectomizadas: estudo prospectivo e randomizado

OBJETIVO: Investigar as repercussões clínicas, biomecânicas e histomorfométricas do ácido zoledrônico em tíbias de ratas osteoporóticas, após ooforectomia bilateral. MÉTODOS: Foram estudadas, prospectivamente, 40 ratas da linhagem Wistar (Rattus novergicus albinus). Com 60 dias de vida, os animais foram aleatorizados em dois grupos de acordo com o procedimento cirúrgico: ooforectomia bilateral (O) (n=20) e pseudo-cirurgia (sham) (P) (n=20). Após 30 dias, os animais foram divididos em quatro subgrupos, de acordo com a administração de 0,1mg/kg de ácido zoledrônico (AZ) ou água destilada (AD): OAZ (n=10), OAD (n=10), PAZ (n=10) e PAD (n=10). Após 12 meses, os animais foram eutanasiados e suas tíbias analisadas. No estudo clínico foi considerado o peso dos animais; no estudo biomecânico foram realizados ensaios compressivos e na análise histomorfométrica foi determinada a área trabecular óssea. RESULTADOS: Os grupos O tiveram aumento de peso significativamente maior que os grupos P (p=0,005). Os grupos OAZ e PAZ tiveram aumento, não significativo, de peso quando comparados aos grupos OAD (p=0,47) e PAD (p=0,68). Os grupos com ácido zoledrônico e com água destilada suportaram carga máxima, semelhante (p=0,2), no momento em que ocorreu fratura. Nos grupos com ácido zoledrônico verificou-se o aumento não significante da área trabecular óssea quando comparados aos grupos com água destilada (p=0,21). Houve correlação positiva entre a área trabecular e a carga máxima (p=0,04; r=0,95). CONCLUSÃO: O ácido zoledrônico não influiu significativamente no peso dos animais. Os resultados mostraram aumento, não significante, tanto da resistência óssea diafisária tibial, como da área trabecular óssea.

Câncer de pulmão: histologia, estádio, tratamento e sobrevida

OBJETIVO: Analisar os principais tipos histológicos, estádio, tratamento e sobrevida dos portadores de câncer de pulmão. MÉTODOS: Estudo retrospectivo a partir da análise dos prontuários de pacientes acompanhados no Hospital das Clínicas da Faculdade de Medicina de Botucatu, num período de seis anos. RESULTADOS: de janeiro de 2000 a janeiro de 2006, foram acompanhados 240 doentes com câncer de pulmão, com predominância do sexo masculino (64%). O tipo histológico mais freqüente foi o carcinoma escamoso (37,5%), seguido pelo adenocarcinoma (30%), carcinoma neuroendócrino (19,6%) e carcinoma de grandes células (6,6%). Apenas 131 pacientes (54,6%) foram tratados. Destes, 52 pacientes (39,7%) foram submetidos à quimioterapia exclusiva, 32 (24,4%) realizaram quimioterapia associada à radioterapia e 47 (35,9%) foram submetidos à cirurgia associada ou não à quimioterapia exclusiva e/ou radioterapia. Somente 27 pacientes (20,6%) foram submetidos à cirurgia exclusiva.Em relação ao estadiamento, 34,4% apresentavam, no momento do diagnóstico, estádio IV, 20,6% estádio IIIB, 16,8% estádio IIIA e os outros 28,2% pertenciam aos estádios I e II. A sobrevida em cinco anos foi de 65% para o estádio I e 25% para os estádios remanescentes. CONCLUSÕES: O tipo histológico predominante foi o carcinoma escamoso e o de menor freqüência foi o carcinoma de grandes células. A maioria se encontrava em estádio avançado ao diagnóstico, estando nos estádios iniciais menos de 30% dos casos. Isto justifica a baixa sobrevida e a pequena quantidade de pacientes submetidos ao tratamento cirúrgico exclusivo, em comparação à maioria que foi submetida à quimioterapia exclusiva.

Projeto político de formação do enfermeiro: contextos, textos, (re)construções

This research analyses politic Project for nursing education, in its articulation with economical, political and social context of 1970s and 1980s in national level and, in special, nurse formation process in FAEN/UERN space, situating it on the context of Brazilian sanitary reformation movement and participation movement. The thesis is firmed on the sense of explaining whether that movement circa the nurse formation process has been able to build necessary instruments for the transformation of biomedical formation model historically consolidated, in the perspective of conceiving another model anchored on social determination of health/illness process, with the purpose of assuring ethical and political commitment with the SUS praised by sanitary reformation. The study visualized the object considering its specificity, its concrete historical determinations and institutional as well as organizational relationships that permeate possibilities of valorizing it, analyzing it, interpreting it and rebuilding it. Its operationalization occurred in three movements, it means, bibliographical review; documents study; interviews and focal groups realized with professors of the institution. We can apprehend as main results that the nurse formation process has incorporated widely spread conceptions by the sanitary reformation movement and participation movement, assuming the commitment with transformation of health services and social reality. Nevertheless it prevails, still, amongst some professors in the same institutional space, the commitment to a predominantly technicist formation, focused on instrumental knowledge. Opinion divergence explicit diversity of conceptions circa education and, as consequence, distinct political commitments, also contradictory to formation. Thus, there is a lacuna between what is foreseen on political pedagogical project and what is rendered in FAEN/UERN, evidencing the clash related to conceptual bases of formation project. Interpretations, divergent political attitudes and resistances to the process allowed several formation ways. However, formation under new conceptual bases, find limits on the context of social politics implemented in Brazil during the 1990s, neoliberal-based, expressed on expansion and consolidation of health private system, managed by market rules, strengthening biomedical formation model. Notwithstanding, there is a favorable to its implementation, starting from the first years of 21st century, moment when Brazilian sanitary reformation reappear on health speech, as well as facing the policy of permanent education in health. This reality explicit a process of dialectical tension between instituted and institutor, anticipating the moment of scission or adaptation and return to what is already known. Despite of clashed, knowledge, accumulated experience, contribution to services, the construction of partnerships out of university space and articulation with national movement of (re)orientation of nurse formation, have been constituted as vital instruments to offer support to formation in FAEN/UERN. Still, we consider necessary the (re)visitation to FAEN/UERN politic pedagogical Project considering the existing and implemented construction, without, yet, depreciate the norther axis of the project at the reaching of its intentionality

Nucleação de vortices e paredes de domínio em nanoestruturas magnéticas

We report a theoretical investigation of the magnetic phases and hysteresis of exchange biased ferromagnetic (F) nanoelements for three di erent systems: exchange biased nanoparticles, exchange biased narrow ferromagnetic stripes and exchange biased thin ferromagnetic lms. In all cases the focus is on the new e ects produced by suitable patterns of the exchange energy coupling the ferromagnetic nanoelement with a large anisotropy antiferromagnetic (AF) substrate. We investigate the hysteresis of iron and permalloy nanoparticles with a square basis, with lateral dimensions between 45 nm and 120 nm and thickness between 12 nm and 21 nm. Interface bias is aimed at producing large domains in thin lms. Our results show that, contrary to intuition, the interface exchange coupling may generate vortex states along the hysteresis loop. Also, the threshold value of the interface eld strength for vortex nucleation is smaller for iron nanoelements. We investigate the nucleation and depinning of an array of domain walls pinned at interface defects of a vicinal stripe/AF bilayer. The interface exchange eld displays a periodic pattern corresponding to the topology of the AF vicinal substrate. The vicinal AF substrate consists of a sequence of terraces, each with spins from one AF subalattice, alternating one another. As a result the interface eld of neighboring terraces point in opposite direction, leading to the nucleation of a sequence of domain walls in the ferromagnetic stripe. We investigated iron an permalloy micrometric stripes, with width ranging from 100 nm and 300 nm and thickness of 5 nm. We focused in domain wall sequences with same chirality and alternate chirality. We have found that for 100nm terraces the same chiraility sequence is more stable, requiring a larger value of the external eld for depinning. The third system consists of an iron lm with a thickness of 5 nm, exchange coupled to an AF substrate with a periodic distribution of islands where the AF spins have the opposite direction of the spins in the background. This corresponds to a two-sublattice noncompensated AF plane (such as the surface of a (100) FeF2 lm), with monolayer-height islands containing spins of one sublattice on a surface containing spins of the opposite sublattice. The interface eld acting in the ferromagnetic spins over the islands points in the opposite direction of that in the spins over the background. This a model system for the investigation of interface roughness e ects. We have studied the coercicivity an exchange bias hysteresis shift as a function of the distance between the islands and the degree of interface roughness. We have found a relevant reduction of coercivity for nearly compensated interfaces. Also the e ective hysteresis shift is not proportional to the liquid moment of the AF plane. We also developed an analytical model which reproduces qualitatively the results of numerical simulations

Traduzindo o economês: metáforas da inflação em textos de jornalismo econômico

The research aimed two objectives: 1st) identifying and describing the metaphors of the inflation, in a corpus of 18 texts of economic journalism, from Joelmir Beting, written in the last trimester of 2002, at the moment of the government s transition of president Fernando Henrique Cardoso to Luiz Inácio Lula Da Silva. 2nd) verifying the recognition of the metaphors by the students of the basic education of a private school from Natal. 91 metaphors had been identified, analyzed in the perspective of the conceptual metaphor s theory, by Lakoff and Johnson (2002), on the basis of the distinction between conceptual metaphor and metaphoric expressions, and between domain-source/domain-target. 10 underlying conceptual metaphors had been inferred, being that the domains-source used more frequently to characterize the inflation had been those ones according to the human being and the animals and, of a less imaginable form, to the ways of transport (car, aircraft). These general conceptual metaphors had been unfolded in other s more specific ones ( animal specifying itself in lion , dragon , dog , etc.). Another result was the identification of metaphoric expressions with two or more meanings , with relation to more than one conceptual metaphor or explicit, in the same expression, two domains-source (for example: armored dragon ) and contributes, of a relevant form, for the semantic struturation of the text. The understanding of the metaphors was verified through an activity of domains-source s identification (10 metaphoric statements and fulfilling of the gap in the phrase the inflation is a/an ) applied in a group of 8th year of the basic education (12-13 years old, with 14 girls and 17 boys) from a school of good social and economic positions from Natal-RN. There weren t great difficulties on the part of the students in recognizing the domains-source involved: about 80% to the great majority of the statements

Evolução termocronológica do sistema de falhas Senador Pompeu-CE

The region of the Senador Pompeu Shear Zone (SPSZ), in the North Tectonic Domain of the Borborema Province (BP), has its recent history associated with to South Atlantic Ocean formation event at the Jurassic. A lot of geologics models have discussed about crustal axis elevation in local scale and large scale (Borborema Province), relative to importants regionals tectonics directions of it. The identification and the relationship among this surfaces, stepped in many topographyc levels by tectonics mecanisms, is dificult because of the erosion process on it. Over there, sedimentary deposits is complex and it has not biostratigraphyc record in continental deposits. The analysis metodology on apatita fission-track, in the region of the SPSZ, purpose the more knowledge about morphotectonics mecanisms of the area and the impruvement of its morphotectonics models. For this, it was moleled the age and thermal history of the 11 apatites samples collected on both sides of this shear zone, taking relationships among other results of the thermochronology studies in the BP. Based on the thermal studies in this search, the region of the BP developed on two distint cooling events, separated for one period of relative stabilited. The first episode occur between 130 and 90 M.y., has been began when the samples cross the 120°C isoterm for last time and fineshed at 70°C. The second moment of the cooling process was began about 30 M.y., when the temperature was 90°C, from this to the equlibrium with present surface temperature at 30°C. Some evidences indicated a relacionship between thermal episodes and uplift events of the regional relief. The fundaments of the interpretation was based mainly on comparatives studies among results of the thermochronology analysis and geologics studies about BP. Nóbrega et al.(2005), e.g., on studies about the Portalegre Shear Zone, got similar results on SPSZ, with some details relative to local tectonic activity. Morais Neto et al. (2000) interpreted two importants cooling events in the BP based on their regional studies, that can be associated to regional uplift events. When Assine (1992) studied the stratigraphyc sequences of the Araripe Basin, in the south of Ceará state, conclude that the abrupt return to continentals condictions from the last sedimentar sequency (albiano-cenomaniane) indicate a regional uplift of the NE region of the Brazil at the 100 M.y., in the Albiano Intermediate/Superior. This ages are compatible to termal model of the SPSZ. This two periods of the thermal history of the BP are completely registered in the apatites samples just one age groups of the fission-track, that it is the most ancient age groups. This one suggest it has happened in response to heating before 75 M.y and it has erased the last report of the first moment relief evolution of the BP. The NNE-SSW and E-W structure reativation can have created ideal condictions for heating and local elevations of the geothermal gradients. The equilibrium between the apatites temperatures of this groups and the regionais temperatures took place about 50 M.y., when the samples of the two ages groups had a simillar evolution to present surfaces temperatures

Identificação de indivíduos vulneráveis no entorno de um hospital universitário: conectando vulnerabilidade, solidariedade e saúde

No entorno de um hospital universitário do interior do estado de São Paulo há pessoas dormindo, se alimentando ou descansando nos gramados e arredores, permanecendo nestes locais durante horas. Este estudo objetivou identificar e caracterizar indivíduos vulneráveis em área externa deste hospital, oferecendo ajuda. A coleta dos dados foi realizada no período de novembro de 2007 a outubro de 2008, semanalmente, em dias e horários sorteados. Identificaram-se pessoas que permaneciam nesses locais, sendo entrevistados 52 sujeitos. Esses indivíduos são, predominantemente, do sexo feminino (67,3%), brancos (51,9%), casados (59,6%), com escolaridade de até quatro anos de estudo (44,2%) e sem profissão definida (84,6%). A maioria aguardava o horário do ônibus da prefeitura de seu município de origem; o tempo médio de espera foi de aproximadamente 90 minutos e grande parte dos sujeitos apresentou necessidades durante os períodos de espera. Foi oferecida ajuda a 15 pessoas que referiram necessidades no momento da entrevista. Concluiu-se que esses indivíduos se encontram em situação de vulnerabilidade individual, social e programática, destacando-se a vulnerabilidade sócio-econômica, apresentam capacidade de autodeterminação reduzida, submetendo-se a condições desfavoráveis por dependerem dos serviços públicos.

Agricultura familiar integrada ao mercado: mediação política e transformações socioespaciais no assentamento rural Vale do Lírio/RN

It s an application about the development of the family agriculture integrated to the market in which is detected the development of the relation of partnership between settled of agrarian reform and the capitalist enterprise. It s shown initially, a conceptual discussion about family agriculture, watching the historical contexts that characterize the expropriation and subordination of the category. This way, the family agriculture is contextual zed in the moment of the modernization of the agriculture, he rising of the social tension in the area of the restructuration of production and the globalization. Finding to understand the agrarian question in Rio Grande do Norte, it s characterized the acting of the state in promoting agrarian reform politics and redistribution of lands. This way, the research demonstrate the reality of the settled of Vale do Lírio, with the partnership of the Caliman Company S. A. in this context, it s emphasized the social geographic transformation in the settler. This way it was realized the analysis of the survey of data in a lot of public department, and the research of the area with use of application form, in 90% percent of the researched group, with interviewing with the leaders of this group and with the manager of the Company. The research demonstrates an analysis of the reality lived by this group, in the perspective the interests of the government and the capital.

Intervenções benéficas durante o parto para a prevenção da mortalidade materna

O caráter multifatorial das complicações e da mortalidade materna torna difícil e demorada a tarefa de seu controle a longo prazo. A atenção profissional à mulher gestante e/ou parturiente representa seguramente elemento chave para a obtenção de bons resultados, tanto maternos quanto perinatais. Partindo-se do pressuposto de que atenção médica profissional ao parto de maneira adequada tem a capacidade de diminuir a ocorrência de complicações associadas à morbidade e mortalidade materna, são apresentadas resumidamente as evidências sobre algumas intervenções incluídas nesta atenção. São enfocadas as evidências derivadas de estudos realizados com extremo rigor metodológico e científico, os ensaios controlados randomizados, sobre intervenções capazes de reduzir as complicações e a mortalidade materna. Estas principais intervenções referem-se basicamente a: atenção institucional ao parto, atendimento profissional capacitado, utilização de parteiras tradicionais em determinados contextos, uso de tecnologias apropriadas incluindo o partograma, local do parto, posição para o parto, uso de episiotomia, tipo de parto, uso de ocitócicos na fase ativa do parto, realização de esforços de puxo no período expulsivo, manejo da dequitação e profilaxia da hemorragia puerperal. Ainda que o efeito de prevenir mortes seja difícil de ser avaliado pela baixa freqüência, sua utilização de forma racional e padronizada, por meio de manuais e normatizações de condutas de serviços, tem um efeito positivo sobre a qualidade da atenção ao nascimento. Isso faz parte do contexto técnico e humano do direito que toda mulher tem ao melhor atendimento possível nesse momento tão especial de sua vida.

Familial cancer: depressed NK-cell cytotoxicity in healthy and cancer affected members

Este estudo se reporta às funções de células natural killer (NK), como adesão, lise e citotoxicidade e de subpopulações de células T em uma família com alta prevalência de pacientes com câncer e que apresentaram: glioblastoma, leucemia mielóide crônica, osteoblastoma, melanoma e carcinomas gástrico, pancreático e cólon retal. Quinze membros dessa família foram estudados, sendo 13 sadios, acompanhados por 5 anos e dois com câncer: glioblastoma e leucemia mielóide crônica. Duas pessoas sadias, no momento da avaliação, desenvolveram posteriormente osteoblastoma mandibular ou melanoma maligno. Como controle, foram avaliados 19 indivíduos saudáveis de faixa etária equivalente. A determinação de linfócitos T CD3+ e de suas subpopulações CD4+ e CD8+ foi realizada empregando-se anticorpos monoclonais e a atividade citotóxica de células NK, avaliada pelo teste de single-cell contra células alvo da linhagem eritroleucêmica K562. Os resultados mostraram que as percentagens de células T totais (CD3+), da subpopulação CD4+ e da relação CD4/CD8 foram significativamente menores nos indivíduos da família estudada em comparação aos valores observados no grupo controle. em todos os membros dessa família a percentagem de formação de conjugados entre células NK-células alvo foi inferior ao valor mínimo observado nos controles. Essa alteração poderia estar relacionada a defeito na expressão de moléculas de adesão, presentes na membrana de células NK, como provável causa das alterações funcionais dessas células. A herança dos mecanismos determinantes desta deficiência pode ser um fator de risco, com valor prognóstico para o desenvolvimento de cancer.
