Comércio internacional e meio ambiente: estímulo à produção sustentável ou mero protecionismo comercial a posição do Brasil em dois casos de litígio

The World Trade Organization (WTO) was established in 1994 as a result of the Uruguay Round, and has as its principal aim advocate for the maintenance of free trade between nations. The preamble of its Constitutive Agreement specifically cites as an institution the goal of achieving sustainable development and the pursuit of protecting and preserving the environment, bringing into the sphere of world trade the idea that concern for the environmental cause is not restricted only the group of environmentalists, but rather has entered the economic landscape in a way not only ideological, but also pragmatic. The General Agreement on Tariffs and Trade (GATT) 1947, part of the GATT 1994, contains a device that allows the adoption of trade restrictive measures, provided that such measures aimed at protecting the environment - Article XX. The Settlement Body (DSB) is part of the WTO and acts in dissolving disputes between the countries motivated by trade. It examines two cases where countries have imposed restrictive trade measures with environmental justification. The first case was closed in 1996, with award of damages given to Brazil, on the breakdown of U.S. environmental legislation imposed on imported gasoline from Brazil - and the second, begun in 2005 and closed in 2007, coming out victorious again Brazil is on the import ban on retreaded tires to Brazil. The objective is to answer the question: how the environment is treated in the midst of trade discussions - which is aimed at its protection or its use with economic objectives in disguise? For the preparation of this work, extensive documentary research was undertaken with the virtual site of the WTO to review the entire production of legal cases and subsequent analysis of the key issue for the work, and literature of authors who have studied the tense relationship between trade international environment. The first case, it could be seen that the political movement performed by the U.S. with the aim of achieving acceptable standards of air quality was an institutional effort to ensure the quality of air, and thus would be inappropriate to say that the regulation of gasoline was merely a disguised trade barrier.However, a careful analysis of the implementation and operation of gasoline regulation may reveal intentions disguised trade and U.S. environmental argument did not hold. The weight of this environment was relegated, since there were clearly outside interests to the environmental cause. The second case, it was realized that, despite clear attempts by the EC to promote ecological dumping, send when brought to Brazil, supposedly a country with weaker environmental structure on surveillance, a residue that, pursuant to internal policies, as could not be sent to their own landfills, the Brazilian discourse remained focused on the environmental cause, and this sort there was the existence of disguised trade barriers, but of importance, at least a priori, the discussion of foreign forces on the environment environment because there is no way to legally justify the reversal of the total understanding of the first judging body, the sight of all the arguments presented by Brazil and the nonsubmission of new facts upon appeal. Still, quite heartening to reflect on the role of trade liberalization on the environment in general, because, while they do not reach a definitive conclusion will reveal positions in both directions, both for and against, the that only adds to the discussions and makes this a very fertile topic for future research

Quality of life and its association with cardiovascular risk factors in a community health care program population

OBJECTIVE: To evaluate quality of life in a population that attended a specific community event on health care education, and to investigate the association of their quality of life with the presence of cardiovascular risk factors INTRODUCTION: Interest in health-related quality of life is growing worldwide as a consequence of increasing rates of chronic disease. However, little is known about the association between quality of life and cardiovascular risk factors. METHODS: This study included 332 individuals. Demographics, blood pressure, body mass index, and casual glycemia were evaluated. The brief version of the World Health Organization Quality of Life questionnaire on quality of life was given to them. The medians of the scores obtained for the physical, psychological, emotional, and environmental domains were used as cutoffs to define higher and lower scores. A multinomial logistic regression model was used to define the parameters associated with lower scores. RESULTS: Diabetes mellitus, dyslipidemia, and obesity were associated with lower scores in the physical domain. Dyslipidemia was also associeted with lower scores in the psychological domain. Male gender and regular physical activity had protective effects on quality of life. Aging was inversely associated with decreased quality of life in the environmental domain. CONCLUSION: The presence of cardiovascular risk factors is related to a decreased quality of life. Conversely, male gender and regular physical activity had protective effects on quality of life. These findings suggest that exercising should be further promoted by health-related public programs, with a special focus on women.

Cytokines and acute-phase serum proteins as markers of inflammatory regression during pulmonary tuberculosis treatment

Tuberculosis is still increasing and was declared a worldwide sanitary emergency by the World Health Organization (WHO) in 1995. Its control is difficult due to long treatment duration and lack of markers of treatment success or failure. Cytokines such as IFN-gamma and TNF-alpha, a central factor in immune response against Mycobacterium tuberculosis, are responsible for the interaction between T lymphocytes and the infected macrophage and are also produced during this interaction. As proinflammatory cytokines have a close relationship with mycobacteria clearance, in fact even preceding it, they could be used as markers for inflammatory activity and response to treatment. Proinflammatory cytokines act in the liver and stimulate a strong local and systemic acute-phase response as a result of homeostatic and physiological responses also induced by them. Acute-phase proteins produced by cytokine activity are useful diagnostic markers that could also be used to monitor treatment response as they can be serially quantified. The objective of this study was to evaluate IFN-gamma, TNF-alpha, IL-10 and TGF-beta production in supernatant of peripheral blood mononuclear cell (PBMC) and monocyte (MO) cultures, as well as serum acute-phase response through total protein, albumin, globulin, C-reactive protein (CRP), alpha-1-acid glycoprotein (AGP), and erythrocyte sedimentation rate (ESR) as regression markers of inflammatory response during pulmonary tuberculosis treatment. Twenty blood donors (G1) from the Blood Bank at Botucatu School of Medicine's University Hospital (BSM-UH) were evaluated once and 28 pulmonary tuberculosis patients (G2): 13 from BSM-UH and 15 from the Bauru State Health Secretariat. Patients were evaluated at three moments of treatment: before (M1), at three months (M2), and at the end (M3). Cytokines were determined in 20ml of peripheral blood (ELISA), with or without activation: lipopolysaccharide (LPS) for MO culture and phytohemagglutinin (PHA) for PBMC culture. Acute-phase protein behavior in G2 throughout treatment was: Globulins: M1> M2, M1> M3 (rho < 0.001); CRP: M1> M2> M3 (.< 0.001); AGP for men: M1> M2, M1> M3 (rho < 0.001); ESR for men: M1> M2, M1> M3 (rho < 0.0016) and for women: M1> M2 (.< 0.025). Comparison between cytokine levels found in supernatant of MO and PBMC cultures, with and without stimulus, in G1 and G2 during treatment showed: TNF-alpha (with/ without LPS) at M1: G2> G1; at M2: G2> G1 (rho < 0.001); (without LPS) at M3: G2> G1 (rho < 0.001), (with LPS) at M3: G2> G1 (rho < 0.028); IFN-. (with and without PHA) at M1: G2> G1; at M2: G2> G1 (rho < 0.001); IL-10 (with and without LPS) at M1: G2> G1; at M2: G2> G1; at M3: G2> G1 (rho < 0.001); TGF-beta (with and without LPS) at M1: G2> G1; at M2: G2> G1 (rho < 0.001), (without LPS) at M3: G2> G1 (rho < 0.001). In G2, all cytokines in supernatant of MO and PBMC cultures, with and without stimulus, showed: M1> M2> M3 (rho < 0.01). Levels of globulins, CRP, AGP, and ESR in patients with pulmonary tuberculosis before treatment (M1) were significantly higher than reference values, suggesting their use as diagnostic markers and indicators of treatment. The CRP decreasing values along treatment could be taken as a marker of the regression of inflammatory process and of response to treatment in patients with pulmonary tuberculosis.Regarding cytokines, there was significant increase in TNF-alpha, IFN-gamma, IL-10, and TGF-alpha levels before and at three months treatment, with and without stimulus; in TNF-a and IL-10 lvels, with and without stimulus, as well as in TGF-alpha levels without stimulus at six months. Patients had higher levels of all studied cytokines than controls before treatment, and these values decreased along treatment. In this study, pulmonary tuberculosis patients showed a Th0 cytokine profile before treatment, with the production of both Th1 (IFN-gamma) and Th2 (IL-10) cytokines, in addition to TNF-alpha inflammatory and TGF-alpha regulatory and fibrosis-inducer cytokines. At the end of treatment, all had evolved to Th2 profile, probably in an attempt to reduce the harmful effects of the proinflammatory activity of the Th1 cytokine profile and of the still above-normal levels of TNF-alpha. The high levels of TGF-alpha, also found in these patients, are related to its important role in the extracellular matrix deposition and fibrosis induction that characterize tuberculosis healing process. IFN-gamma was the only cytokine reaching normal levels at the end of treatment, which suggests its use as a marker of response to treatment.

Avaliação da assistência ao parto em maternidade terciária do interior do Estado de São Paulo, Brasil

OBJETIVOS: avaliar a estrutura e o processo de assistência ao parto e ao recém-nascido desenvolvidos na maternidade e na unidade de neonatologia de uma instituição hospitalar de nível terciário do interior do Estado de São Paulo, Brasil. MÉTODOS: estudo descritivo, transversal, voltado para a análise da adesão às normas preconizadas pelo Ministério da Saúde e Organização Mundial da Saúde em relação ao parto, avaliando-se os recursos existentes e as atividades desenvolvidas durante a assistência. Os dados foram colhidos nos anos de 2004 e 2005, a partir de entrevista com o gestor da maternidade, análise de 293 prontuários amostradose observação de 29 partos realizados. RESULTADOS: a avaliação da estrutura evidenciou a disponibilidade de equipamentos, instrumentais e medicamentos, de obstetra, pediatra e anestesista eausência de quartos de pré-parto, parto e puerpério.Na análise do processo observouse, entre outras,frequências regulares relacionadas à verificação de pressão arterial e ausculta dos batimentos cardíacos fetais; o preenchimento do partograma foi satisfatório; na assistência ao recém-nascido, foram insatisfatórios o aleitamento na primeira hora de vida e ocontato pele a pele. CONCLUSÕES: algumas práticas úteis no partonormal foram pouco utilizadas. Percebese uma tendência à incorporação de práticas baseadas em evidências científicas, quando se considerou a realização de procedimentos como tricotomia, enteroclisma e episiotomia, demonstrando uma mudançapositiva na assistência ao parto.

Uso de álcool e drogas por estudantes de medicina da Unesp

INTRODUÇÃO: O objetivo deste trabalho foi analisar a prevalência do uso de drogas por estudantes da Faculdade de Medicina de Botucatu - Unesp, comparada com outras oito escolas médicas paulistas (uso na vida, nos últimos 12 meses e nos últimos 30 dias). A pesquisa foi realizada entre 1994 e 1995, com 5.227 estudantes do 1o ao 6o ano de graduação. MATERIAL E MÉTODO: Foi usado um questionário de auto-respostas, anônimo, incluindo o questionário da Organização Mundial da Saúde para levantamento de uso de drogas e álcool. Setenta e um por cento (3.725) dos alunos responderam ao mesmo, e destes, 421 eram de Botucatu. RESULTADOS: Não houve diferenças estatisticamente significantes entre escolas e, nos 30 dias anteriores ao preenchimento do questionário, a prevalência do uso de drogas para os estudantes de Botucatu foi a seguinte, com a variação entre outras escolas mostrada entre parênteses: álcool 50% (42-50%); tabaco 7% (7-13%); solventes 8% (7-12%); maconha 6% (6-16%); benzodiazepínicos (BZD) 3% (2-9%); cocaína 0,5% (0,2-4%); anfetaminas 1 % (0-1%). Embora tenha se encontrado um uso crescente de todas as drogas do 1o ao 6o ano, e em especial os BZD, os estudantes não aprovam este uso. A análise de regressão logística indicou que o uso de álcool e drogas foi favorecido por: a) ser homem; b) perder aulas sem razão e referir ou ter muito tempo livre nos finais de semana; e c) ter uma atitude favorável em relação ao uso de álcool e drogas. Diferentemente de outras escolas, na Unesp não houve diferenças estatisticamente significantes de gênero em relação ao uso de tranqüilizantes. No entanto, as mulheres iniciam uso mais precocemente e o fazem mais freqüentemente. Também as mulheres já faziam uso de maconha antes de entrar para a faculdade (30% mulheres X 10% homens), o contrário ocorrendo com solventes (50% homens X 2% mulheres), sendo essas diferenças estatisticamente significantes. CONCLUSÕES: Embora a pesquisa tenha focalizado o uso (não abuso ou dependência), os resultados sugerem a necessidade de as universidades estabelecerem uma política clara de orientação sobre uso de drogas e álcool para os estudantes, incluindo mudanças curriculares e programas de prevenção.

Prevention of mental ill-health and suicide: Public health perspectives

According to the World Health Organization (WHO) estimates for the year 2020, approximately 1.5 million people will commit suicide, and at least 10 times that many will make an attempt. This paper offers a brief overview of the current state of the epidemiology of suicide, a burgeoning public health problem. The information provided is based in large measure on reports of suicide mortality from 130/193 countries. In order to contextualize these data, this paper explores the contribution of both individual and sociocultural factors that influence suicidal behavior, from which much has been learned. Outlining the history of attempts by international and national organizations like WHO, United Nations, member states in the European community and other countries to regularize identification and suicide reporting procedures, this paper also demonstrates that serious knowledge gaps remain. Minimal requirements for successful evidence-based interventions are presented. (C) 2010 Published by Elsevier Masson SAS.

Qualidade de vida no transtorno obsessivo-compulsivo: uma revisão

CONTEXTO: O transtorno obsessivo-compulsivo (TOC) foi considerado pela Organização Mundial da Saúde como a 10ª causa de anos vividos com incapacidade, mas pesquisas sobre qualidade de vida (QV) nesse transtorno ainda são relativamente raras. OBJETIVOS: O objetivo deste trabalho foi fazer uma revisão convencional da literatura a respeito de estudos sobre qualidade de vida no TOC, publicados em português e inglês. MÉTODOS: A busca de artigos foi feita pelos sistemas MEDLINE, PsicoInfo e LILACS, cobrindo o período de 1980 a 2007, utilizando-se como palavras-chave: qualidade de vida, transtorno obsessivo-compulsivo, prejuízo funcional e incapacidade. RESULTADOS: Estudos populacionais apresentam indicadores indiretos de comprometimento na QV em pessoas com TOC, como mais desemprego, menor renda e menor índice de união conjugal estável, além de taxas relativamente altas de ideação e tentativas de suicídio. Estudos clínicos encontraram mais comprometimento na QV no TOC em comparação com algumas doenças clínicas crônicas, outros transtornos de ansiedade, quadros depressivos e mesmo esquizofrenia, em alguns aspectos. CONCLUSÃO: O impacto negativo do TOC sobre a QV de seus portadores pode ser grande, afetando vários domínios da vida e repercutindo também nos familiares. A reabilitação psicossocial deve ser vista como parte integrante essencial do tratamento e é preciso aumentar a conscientização da população sobre o problema, assim como o acesso a tratamentos adequados, para minimizar tal impacto, por vezes devastador.

Tracoma em crianças do ensino fundamental no município de Bauru: Estado de São Paulo, Brasil

OBJETIVO: Foi realizado um estudo transversal, por amostragem de escolares, frequentadores das escolas estaduais de Bauru, São Paulo, com o objetivo de detectar possíveis portadores de tracoma. MÉTODOS: Foram examinadas 1.749 crianças do ensino fundamental, de 6 a 14 anos, durante o ano de 2005. As escolas foram escolhidas por sorteio, de acordo com o número de estudantes e com a localização da escola dentro do setor da cidade (centro, região intermediária e periferia). O diagnóstico dos casos foi clínico, seguindo as normas da Organização Mundial de Saúde (OMS), confirmado laboratorialmente pelo método da imunofluorescência direta para detecção de Chlamydia trachomatis. RESULTADOS: A prevalência de tracoma inflamatório foi de 3,8%, tendo sido diagnosticado tracoma folicular em 3,7% e tracoma intenso em 0,06% das crianças examinadas. As crianças com tracoma moravam principalmente na região intermediária e periférica da cidade, áreas onde o fornecimento de água pode ser descontínuo e o tratamento do esgoto pode estar ausente. Um programa de controle foi desenvolvido e os comunicantes foram diagnosticados e tratados. CONCLUSÃO: A prevalência de tracoma inflamatório em Bauru - Estado de São Paulo - é de 3,8%. Além da oportunidade de reconhecer e tratar os portadores e contatantes, os autores realçam o fato positivo da mobilização da comunidade bauruense no sentido de prevenir a cegueira pelo tracoma.

Association of insecticide use and alteration on Aedes aegypti susceptibility status

Dengue and dengue hemorrhagic fever, vector-borne diseases transmitted by the mosquito Aedes aegypti, are presently important public health problems in Brazil. As the strategy for disease control is based on vector control through the use of insecticides, the development of resistance is a threat to programs efficacy. The objective of this study was to compare the Aedes aegypti susceptibility in nine vector populations from the state of São Paulo and seven from Northeast region of Brazil, since there was a difference on group of insecticide used between the areas. Bioassays with larvae and adult were performed according to the World Health Organization methods.The results showed higher resistance levels to organophosphates group in populations from the Northeast region where this group was used for both larvae and adult control than in São Paulo where organophosphates were used for larvae and pyretroids for adult control. Resistance to pyretroids in adults was widespread in São Paulo after ten years of use of cypermethrin while in vector populations from the Northeast region it was punctual. The difference in resistance profile between the areas is in accordance to the group of insecticide used.

The role of salt abuse on risk for hypercalciuria

Background: Elevated sodium excretion in urine resulting from excessive sodium intake can lead to hypercalciuria and contribute to the formation of urinary stones. The aim of this study was to evaluate salt intake in patients with urinary lithiasis and idiopathic hypercalciuria (IH).Methods: Between August 2007 and June 2008, 105 lithiasic patients were distributed into 2 groups: Group 1 (n = 55): patients with IH (urinary calcium excretion > 250 mg in women and 300 mg in men with normal serum calcium); Group 2 (n = 50): normocalciuric patients (NC). Inclusion criteria were: age over 18 years, normal renal function (creatinine clearance >= 60 ml/min), absent proteinuria and negative urinary culture. Pregnant women, patients with intestinal pathologies, chronic diarrhea or using corticoids were excluded. The protocol of metabolic investigation was based on non-consecutive collection of two 24-hour samples for dosages of: calcium, sodium, uric acid, citrate, oxalate, magnesium and urinary volume. Food intake was evaluated by the three-day dietary record quantitative method, and the Body Mass Index (BMI) was calculated and classified according to the World Health Organization (WHO). Sodium intake was evaluated based on 24-hour urinary sodium excretion.Results: The distribution in both groups as regards mean age (42.11 +/- 10.61 vs. 46.14 +/- 11.52), weight (77.14 +/- 16.03 vs. 75.99 +/- 15.80), height (1.64 +/- 0.10 vs. 1.64 +/- plusorminus 0.08) and BMI (28.78 +/- 5.81 vs. 28.07 +/- 5.27) was homogeneous. Urinary excretion of calcium (433.33 +/- 141.92 vs. 188.93 +/- 53.09), sodium (280.08 +/- 100.94 vs. 200.44.93 +/- 65.81), uric acid (880.63 +/- 281.50 vs. 646.74 +/- 182.76) and magnesium (88.78 +/- 37.53 vs. 64.34 +/- 31.84) was significantly higher in the IH group (p < 0.05). There was no statistical difference in calcium intake between the groups, and there was significantly higher salt intake in patients with IH than in NC.Conclusions: This study showed that salt intake was higher in patients with IH as compared to NC.

Características anatomoclínicas dos linfomas caninos na região de Botucatu, São Paulo

Estudaram-se as características anatomoclínicas dos linfomas em cães da região de Botucatu, São Paulo. O material utilizado foi colhido de 34 cães portadores de linfoma maligno, dos quais nove eram da raça Pastor-Alemão, nove sem raça definida, cinco da raça Boxer, três animais da raça Dobermann e oito outros cada um de uma raça, 68% deles machos. A idade variou de 1 a 13 anos, com média de 6,2 anos. O estabelecimento do estádio dos linfomas foi baseado nos critérios estabelecidos pela Organização Mundial de Saúde. No momento do diagnóstico, 32 animais apresentavam-se nos estádios clínicos III, IV ou V. Apenas dois foram enquadrados no estádio II. A forma anatômica mais freqüente foi a multicêntrica, diagnosticada em 31 animais. A forma tímica, diagnosticada em dois animais, e a digestiva, em um animal, foram as outras formas anatômicas encontradas.

Chicken embryo related (CER) cell line for quantification of rabies neutralizing antibody by fluorescent focus inhibition test

Levels of rabies virus neutralization antibody in sera from vaccinated dogs and cattle were either measured by mouse neutralization test (MNT) or by rapid fluorescent focus inhibition test (RFFIT), performed on CER monolayers. The two tests were compared for their ability to detect the 0.5 International Units/ml (I.U.) recommended by the World Health Organization (WHO) as the minimum response for proof of rabies immunization. A significant correlation was found between the two tests (n = 211; r = 0.9949 in dogs and 0.9307 in cows, p < 0.001), good sensitivity (87.5%), specificity (94.7%) and agreement (96.6%) as well. RFFIT method standardized on CER cell system for neutralizing antibodies detection turns the diagnosis easier and less expensive, specially when a great number of samples must be tested from endemic areas as commonly found in Brazil.

Rabies neutralizing antibody detection by indirect immunperoxidase serum neutralization assay performed on chicken embryo related cell line

The aim of this study was to evaluate the indirect immunoperoxidase virus neutralization (IPVN) and mouse neutralization test (MNT) to detect antibodies against rabies virus from vaccinated dogs and cattle. The IPVN was set up for the ability to measure 0.5 International Units/ml (IU) of antibody required by the World Health Organization and the Office International des Epizooties as the minimum response for proof of rabies immunization. IPVN was developed and standardized in chicken embryo related (CER) cell line when 141 dog and 110 cattle sera were applied by serial five-fold dilutions (1:5, 1:25, 1:125) as well as the positive and negative reference controls, all added in four adjacent wells, of 96-well microplates. A 50 µl amount of CVS32 strain dilution containing 50-200 TCID50/ml was mixed to each serum dilution, and after 90 min 50 µl of 3 x 10(5) cells/mlcell suspension added to each well. After five days of incubation, the monolayers were fixed and the IPVN test performed. The correlation coefficient between the MNT and IPVN performed in CER cells was r = 0.9949 for dog sera (n = 100) and r = 0.9307 for cattle sera (n = 99), as well as good specificity (94.7%), sensitivity (87.5%), and agreement (96.6%) were also obtained. IPVN technique can adequately identify vaccinated and unvaccinated animals, even from low-responding vaccinated animals, with the advantage of low cost and faster then MNT standard test.

Prevalence of Malocclusion and Related Oral Habits in 5-to 6-year-old Children

Purpose: To verify the prevalence of malocclusion and the influence of harmful oral habits on deciduous dentition in 5- and 6-year-old children enrolled in Brazilian public elementary schools during 2010.Materials and Methods: Exams were conducted in 1385 children from 56 Brazilian elementary schools using the method recommended by the World Health Organization (WHO) for epidemiological surveys on oral health. Information about the type of arch, social and economic data and harmful oral habits of the children were collected through a structured questionnaire.Results: In relation to canine occlusion, a high prevalence of Class I (74.5%), followed by Class II (19.4%), was found. Among all participants, 22% showed high overjet, 7.8% showed edge-to-edge occlusion and 2.3% showed anterior crossbite. In relation to overbite, 13.2% had short overbite, 14.3% open bite and 16.8% high overbite. The presence of posterior crossbite occurred in 14.6% of children. Maxillae predominantly exhibited the type I arch (67.9%) and mandibles predominantly exhibited type II (51.7%). In relation to harmful oral habits, 43.4% used a pacifier, 84.8% used a bottle and finger sucking was reported by 17.2%.Conclusion: There was a high prevalence of malocclusion associated with oral habits harmful to deciduous dentition.
