The Programa de Aquisição de Alimentos was created by the Lula administration (2003) as part of Fome Zero (Zero Hungry). This program aims to ensure access to food for people living in food and/or nutritional insecure situation and strengthen family agriculture, by food that is pushased by the government. Considering the importance of this program as a differentiated policy that we abode in the analysis far of its implementation on national scale, as its operationalization in a specific context, with the spatial cutout of the municipality Dracena, located on São Paulo state western portion. It was found that, either in national and municipal levels, the program presented a growth on the number of approved projects, participating producers, benefited institutions and resource values. However, even with such expansion, the scope of this program is still quite limited and at the same time, too concentrated in spatial terms.

The purpose of this study envisaged the quantification of skin and respiratory exposures occasioned by work conditions during pesticide spraying of citrus fruits using hand gun sprayers; the evaluation of the efficiency of individual and group protection measures for the workers; the determination of workers' most exposed body regions; and the classification of work conditions, with and without the tested work-safety protection measures as recommended for the registered pesticides used to control the main pests and diseases that attack these types of trees and fruits. The AZR protection equipment proved to be the most efficient for the tractor driver, when spraying using pistol sprayers. The two sets of individual protection equipment that were checked also proved to be efficient. The most exposed regions of the tractor driver's body were the thighs, the front of the legs, the feet and hands. The most exposed regions of the individual sprayer working on foot were the hands and feet.

The objectives of this study were: a) to quantify dermal and respiratory exposure resulting from work conditions in the application of pesticides on citrus crops using a air-assisted sprayer and by preparing the spray in a tank with a capacity of2.000 L; b) to evaluate the measures of individual protection for these workers; c) to determine the areas of the worker's body most exposed; and d) to classify the work conditions with and without the protective measures tested, with regard to the occupational safety of the recommendations for the pesticides used in controlling the main pests and diseases of this crop. It was shown that for the tractor driver and sprayer operator applyng pesticides on citrus trees, the most efficient protective measures were the AZR ensemble and the Real cabin. The AZR ensemble was effective in controlling exposure of the spray preparer, because it was sufficient to turn work conditions from unsafe to safe. The area of the body most exposed under the two work conditions studied was the hands of the workers.

In the last two decades, the trend in security policies in Brazil shows the shift path on public policies, that allows us to see changes from state building policies to the growing presence of others public branches and civil society. From state and bureaucratic based functions, security tends to see more as problem of management and public agenda setting, mainly, with growing participation on state and local levels. Nevertheless the challenges remain in terms of changes in the whole picture of security in the country. The article explores some of them, without the desire of comprehensiveness.

The implantation of military regimes in South America, from the mid-1960s, happened in the context of the Cold War. As a result, both the occurrence of military coups and the plans and actions for the national defense of the Southern Cone States occurred following the logic of that period and the concept of hemispheric defense preached by the United States, with priority in combating the so-called internal subversion. Thus, the need to combat the “internal enemy” has led these countries to participate in hemispheric mechanisms or create his own arrangements for coordination. The article starts from the conflict hypothesis used by the military governments in their military planning to analyze the actions carried out against leftist movements, including coordination between the governments of the Southern Cone. The understanding of the defense concepts against Soviet communism allows us to understand that the groups placed against the military governments were seen as a danger to the State and, in that “state of war”, the means justified the ends.

Identificar as famílias que apresentem estoque e que façam uso de medicamentos, bem como avaliar as condições de armazenamento, segurança e uso desses produtos pelos usuários. O estudo foi conduzido em um município do estado de São Paulo e realizado com usuários cadastrados na Estratégia Saúde da Família (ESF) localizada no bairro Jardim das Hortências (uma das dez unidades de ESF que o município possui), que conta com 1132 domicílios cadastrados. Para a seleção da amostra foi realizado sorteio aleatório estratificado (134 domicílios, IC 95%). Para a coleta, realizada durante o primeiro semestre de 2011, os usuários dos domicílios selecionados foram entrevistados aplicando-se um formulário semi-estruturado. Participaram do estudo 118 (88,0%) domicílios, dos quais 112 (95,0%) possuíam medicamentos, que eram estocados em lugares inseguros ou inadequados em 75,4% destes. A automedicação – tanto com Medicamentos Isentos de Prescrição (MIP), quanto com Medicamentos Sujeitos a Prescrição (MSP) e aqueles Sujeitos a Controle Especial (SCE) – era prática comum em 46 (47,4%) domicílios. Falta de identificação e segurança nos medicamentos armazenados foi observada em 60 (53,6%) domicílios. A maioria dos domicílios possui estoque de medicamentos (feito de forma inadequada ou insegura) e/ou apresenta especialidades com falta de identificação e segurança, o que pode levar a intoxicações ou inefetividade terapêutica. A Assistência Farmacêutica, no âmbito do Sistema Único de Saúde (SUS), carece de iniciativas sociais com ações voltadas ao usuário de medicamentos, deficiência que pode ser sanada pela presença do farmacêutico, essencial para a promoção do Uso Racional de Medicamentos (URM), nas unidades da ESF, que, por meio da Atenção Farmacêutica, pode: identificar, corrigir e prevenir problemas (reais e potenciais) relacionados a medicamentos, os quais podem estar associados com agravos a saúde

O uso de radiações ionizantes (R.I.), nas mais variadas atividades tem aumentado nas últimas décadas. Com o avanço tecnológico, novos e sofisticados equipamentos emissores de R.I. tem surgido no cenário nacional, o que torna imperativo a difusão do conhecimento sobre os conceitos de proteção radiológica junto à comunidade em geral, e neste sentido, o curso de física médica desenvolve um importante papel, quer seja no aspecto informativo quanto formativo de cidadãos e profissionais críticos e politicamente corretos, que possam contribuir com as Políticas Públicos dos órgãos normatizadores e fiscalizadores das atividades de vigilância sanitária. Conforme a legislação atual (Resolução SS-625 de 14/12/1994, da Secretaria de Estado da Saúde, e Portaria 453 de 01/06/1998 da Vigilância Sanitária do Ministério da Saúde), todos os serviços que utilizam radiações ionizantes devem realizar testes de avaliação dos parâmetros radiométricos dos equipamentos emissores de R.I., sendo exigidos as medidas de Levantamento Radiométrico das instalações, o Teste de Radiação de Fuga do cabeçote emissor e a implementação de Programa de Garantia de Qualidade dos equipamentos e dos procedimentos radiológicos. Este procedimento tem como objetivo principal a obtenção de imagens radiográficas com qualidade e a segurança de pacientes e profissionais, evitando a exposição desnecessária à radiação de pacientes e profissionais. A correta realização de procedimentos radiológicos além de reduzir a dose nos pacientes também promove significativa diminuição nos custos, por não haver necessidade da repetição dos exames. No Brasil, conforme dados da Secretaria de Atenção à Saúde SAS/MS, atualmente existem instalados 4.469 mamógrafos, 25.930 aparelhos de raios-x médicos, 39.438 aparelhos de raios-x odontológicos e...(Resumo completo, clicar acesso eletrônico abaixo)

The Nuclear Medicine is a medical specialty which uses different radioisotopes for diagnostic and therapeutic purposes. The isotopes are radioactive elements which are administered in vivo and present distribution to specific organs or cell types. The knowledge of radioactivity and notions related to ionizing radiation allow to contextualize the radiological protection measures to be taken in Nuclear Medicine. So it is possible to minimize unnecessary exposure to patients, the public, and individuals occupationally exposed and the environmental. For this it is necessary to relate the physical and technological bases apply to this mode with the standards established by regulatory agencies, including the CNEN (National Nuclear Energy Commission) and ANVISA (National Agency for Sanitary Vigilance). In this scenario, it is important that the theoretical endorse the activities which are periodically audited for verification of compliance with the standards that aim to radioprotection. One role of the Medical Physicist in these services is, therefore, act as Radiation Protection Supervisor exerting numerous activities and ensuring compliance with these standards. In this context the stage in the area of Nuclear Medicine was developed in many customers of the enterprise Rad Dimenstein & Associados LTDA, among them the hospitals Israelita Albert Einstein (HIAE), Nossa Senhora de Lourdes (HNSL), Santa Paula (HSP), Cruz Azul (CRAZ), Grupo Fleury, among other clinics. Following the routine and then carrying out various activities pertaining to the Medical Physicist in the area, it was noted that the measures and actions are extremely effective and fundamental in terms of radiological protection

A tripanossomíase americana – Doença de Chagas – é uma parasitose típica de países tropicais e subdesenvolvidos. Devido a grande abrangência da doença, somada a dificuldade encontrada pelos pacientes para adquirir os medicamentos, Chung et al. (1996) sintetizaram o pró-fármaco hidroximetilnitrofural (NFOH). Esse derivado do nitrofural (NF), em estudos preliminares, apresentou resultados significativamente superiores aos observados com benznidazol e nitrofural, disponíveis para a terapia convencional. O presente estudo teve como objetivo a avaliação preliminar do potencial de hepatotoxicidade e cardiotoxicidade do NFOH quando administrado a coelhos albinos. O protocolo experimental se deu através da avaliação da atividade sérica dos biomarcadores hepáticos AST, ALT, GGT e bilirrubina, e do cardíaco CK-MB. Os animais foram divididos em três grupos (n=5), que receberam NFOH, NF e o veículo DMSO duas vezes ao dia, durante 24 dias. Para realização das análises foram coletadas amostras de sangue a cada seis dias. Os testes foram realizados através de kits bioquímicos para diagnóstico (Labtest®). Os níveis de AST e ALT dos grupos expostos aos fármacos apresentaram significativa diminuição com relação ao grupo controle, a bilirrubina não apresentou alterações significativas, e a atividade sérica da GGT apresentou-se elevada tanto nos grupos NFOH e NF quanto no grupo controle. Foi observada alta mortalidade entre os animais expostos ao NF e os valores de CK-MB foram significativamente superiores aos valores de referência descritos em literatura, sugerindo dano cardíaco. Tendo como base tais resultados, concluímos que o pró-fármaco não originou prejuízos relacionados ao tecido hepático, porém com relação à cardiotoxicidade há necessidade de estudos posteriores.
