Vigilância em saúde no Brasil: os desafios dos riscos sanitários do século XXI e a necessidade de criação de um sistema nacional de vigilância em saúde

The technological development experienced in the contemporary world are transforming society and relations between State and people. The mobility of human being has reached levels never before imagined and a person can move from one side of the world to the other side in less than 24 hours. This mobility also includes goods and services, giving the keynote of the globalized world of the XXI Century. In this context, the risks of diseases and others health problems are intensely amplified. Nowadays, an epidemic that begins in China can arrive in Brazil the following day. Brazil recognizes health as a universal right and also consider it a State's obligation. Therefore, the State of Brazil is obligated to organize itself to eliminate or control health risks. Today, the organization of the Brazilian State regarding the surveillance of risks of diseases and other health problems is fragmented and includes sanitary surveillance (focused on goods, products and services), epidemiological surveillance (diseases and investigations of other risks) and environmental surveillance in health (the environment in general, including the workplace). This fragmentation causes problems for the management and consolidation of strategic information for health protection. Brazil has the need to think about an other model of organization that put together all "kinds" of surveillances within a single coordinated system, called the National System of Health Surveillance, which would be able to coordinate the various specialties of health surveillance that exists in the country in order to provide a effective system of information and health surveillance, able to face emergency situations of public health

Pectinase production by solid fermentation from Aspergillus niger by a new prescription experiment

The Ordos Plateau in China is covered with up to 300,000 ha of peashrub (Caragana) which is the dominant natural vegetation and ideal for fodder production. To exploit peashrub fodder, it is crucially important to optimize the culture conditions, especially culture substrate to produce pectinase complex. In this study, a new prescription process was developed. The process, based on a uniform experimental design, first optimizes the solid substrate and second, after incubation, applies two different temperature treatments (30 degrees C for the first 30 h and 23 degrees C for the second 42 h) in the fermentation process. A multivariate regression analysis is applied to a number of independent variables (water, wheat bran, rice dextrose, ammonium sulfate, and Tween 80) to develop a predictive model of pectinase activity. A second-degree polynomial model is developed which accounts for an excellent proportion of the explained variation (R-2 = 97.7%). Using unconstrained mathematical programming, an optimized substrate prescription for pectinase production is subsequently developed. The mathematical analysis revealed that the optimal formula for pectinase production from Aspergillus niger by solid fermentation under the conditions of natural aeration, natural substrate pH (about 6.5), and environmental humidity of 60% is rice dextrose 8%, wheat bran 24%, ammonium sulfate ((NH4)(2)SO4) 6%, and water 61%. Tween 80 was found to have a negative effect on the production of pectinase in solid substrate. With this substrate prescription, pectinase produced by solid fermentation of A. niger reached 36.3IU/(gDM). Goats fed on the pectinase complex obtain an incremental increase of 0.47 kg day(-1) during the initial 25 days of feeding, which is a very promising new feeding prospect for the local peashrub. It is concluded that the new formula may be very useful for the sustainable development of and and semiarid pastures such as those of the Ordos Plateau. (c) 2005 Elsevier Inc. All rights reserved.

Chinese wool auctions: Failed agribusiness reform or future marketing channel?

The spectacular though short-lived operation of China's wool auctions graphically illustrates problems in reforming China's agribusiness sector. A selective coverage of product type and participants, a highly contrived process of price discovery, and an urgent need for parallel reform in related areas all led to the demise of the auctions and are a barrier to their re-emergence as a viable wool marketing channel. Despite the challenges facing wool auctions, this paper argues that they still have much to offer the marketing of wool in China.

Hypomania: a transcultural perspective

This study examined the transcultural robustness of a screening instrument for hypomania, the Hypomania Checklist-32. first revised version(HCL-32 R1) It was carried out in 2606 patients from twelve countries in five geographic regions (Northern, Southern and Eastern Europe, South America and East Asia) In addition, GAMIAN Europe contributed data from its members Exploratory and confirmatory factor analyses were used to examine the transregional stability of the measurement properties of the HCL-32 R 1, including the influence of sex and age as covariates A cross cultures, a two-factor structure was confirmed the first factor (F 1) reflected the more positive aspects of hypomania (being more active, elated, self-confident, and cognitively, enhanced), the second factor (F2) reflected the more negative aspects (being irritable, impulsive, careless. more substance use). The measurement properties of the HCL-32 R1 were largely invariant across cultures Only few items showed transcultural differences in their relation to hypomania as measured by the test F2 was higher among men and in more severe manic syndromes, F1 was highest in North and East Europe and lowest in South America Vie scores decreased slightly with age The frequency of the 32 items showed remarkable similarities across geographic areas, with two exceptions. South Europeans had lower symptom frequencies in general and East Europeans higher rates of substance use These findings support the international applicability of the HCL-32 R1 as a screening instrument for hypomania

Dam worms

Human and animal infection rates with the Oriental schistosome have steadily declined in China over the last half-century, but the Three Gorges Dam may reverse this decline by creating new, or enlarging existing, ideal environments for the worm and its aquatic snail intermediate host.

Behavior of argon gas release from manganese oxide minerals as revealed by Ar-40/Ar-39 laser incremental heating analysis

Manganese oxides in association with paleo-weathering may provide significant insights into the multiple factors affecting the formation and evolution of weathering profiles, such as temperature, precipitation, and biodiversity. Laser probe step-heating analysis of supergene hollandite and cryptomelane samples collected from central Queensland, Australia, yield well-defined plateaus and consistent isochron ages, confirming the feasibility, dating very-fined supergene manganese oxides by Ar-40/(39) Ar technique. Two distinct structural sites hosting Ar isotopes can be identified in light of their degassing behaviors obtained by incremental heating analyses. The first site, releasing its gas fraction at the laser power 0.2-0.4 W, yields primarily Ar-40(atm), Ar-38(atm), and Ar-36(atm), (atmospheric Ar isotopes). The second sites yield predominantly Ar-40* (radiogenic Ar-40), Ar-39(K), and Ar-38(K) (nucleogenic components), at similar to0.5-1.0 W. There is no significant Ar gas released at the laser power higher than 1.0 W, indicating the breakdown of the tunnel sites hosting the radiogenic and nucleogenic components. The excellent match between the degassing behaviors of Ar-40*, Ar-39(K), and Ar-38(K) suggests that these isotopes occupy the same crystallographic sites and that Ar-39(K) loss from the tunnel site by recoil during neutron irradiation and/or bake-out procedure preceding isotopic analysis does not occur. Present investigation supports that neither the overwhelming atmospheric Ar-40 nor the very-fined nature of the supergene manganese oxides poses problems in extracting meaningful weathering geo-chronological information by analyzing supergene manganese oxides minerals.

Cancelamentos de cirurgias no próprio dia

RESUMO - INTRODUÇÃO: Para garantir a qualidade e universalidade dos cuidados de Saúde, é fundamental, que os recursos disponíveis sejam bem utilizados, evitando desperdícios. Os resultados de um hospital estão diretamente ligados aos resultados do Bloco Operatório. A taxa de utilização e a taxa de cancelamentos são indicadores da atividade dos Blocos Operatórios. Realizou-se um estudo piloto no Hospital Dr. José de Almeida em Cascais. OBJECTIVO: Conhecer as taxas de cancelamento de cirurgias no próprio dia. METODOLOGIA: Estudo descritivo longitudinal, retrospectivo, quantitativo, às cirurgias agendadas, entre 1 de Janeiro e 31 de Março de 2012. Utilizou-se a estatística descritiva e a inferência estatística através de testes de independência de variáveis. RESULTADOS: 1524 cirurgias agendadas, canceladas 205, com 100 cancelamentos no próprio dia. Os resultados revelam na globalidade taxas de cancelamento (13,45%) inferiores às fornecidas pelo Ministério da Saúde em relação a 2008, 2009 e 2010, com 28,4%, 26,0% e 26,6% respectivamente. No entanto, as taxas de cancelamento no próprio dia são semelhantes 48,78% no estudo e, entre 44,1% e 50,5% nos dados do Ministério da Saúde. Os estudos internacionais consultados revelam taxas globais de 0,34% na China (Sung,2010) num hospitalar multidisciplinar e 30,3% (taxa de cancelamentos no dia) na Índia (Garg, 2009). CONCLUSÃO: A imputação do motivo de cancelamento é feita ao “serviço/ hospital” ou a “outros”, o utente apresenta uma taxa baixa de imputação do motivo de cancelamento. Foi encontrada uma relação de dependência entre as variáveis, com exceção da relação entre data do cancelamento e a especialidade cirúrgica. Assim, considera-se pertinente a realização de um estudo mais aprofundado e abrangente deste fenómeno nas instituições de saúde em Portugal.

Traditional Chinese materia medica: a retrospect and prospect

For thousands of years, traditional medicine and remedies have been practed and used in the fight against disease in China. They have proved to be valuable and the distillate of vast historical experience based on field-tested human experiments, long-term observations and clinical trials. The Chinese people belive that traditional medicine is consistent with theirown culture. Endowed with a unique theoretical system and provided outstanding clinical results, traditional Chinese medicine continues to play an important role in helping the Chinese nation flourish. The recent study of traditional medicinal plants in Chine has given us confidence that what was recorded in ancient medical literature through empirical observations is indeed still coindicent with the concepts of modern chemistry, pharmacology and medicine. The task of revealing what is valid and efficacious should be retained, and what is mythic and invalid should be discarded in traditional Chinese medicine may require scientific research lasting for several generations. Therfore, multidisciplinary cooperation and international collaboration in this field would be essential. Systematic coordination of work in traditional medicine by word organizations, national governments, private foundations and individual scientists is a requisite as well.

La medicina Xinesa a la Xina contemporània

La medicina occidental és la imperant a tot el planeta. Malgrat tot, a la Xina la medicina tradicional hi té un pes important. La convivència entre totes dues visions de la salut i la malaltia -l'occidental i l'oriental- no és senzilla. En aquest treball es fa un recorregut pel sistema de salut xinès per a fer una aproximació a la situació de la medicina xinesa a la Xina contemporània.

Art contemporani xinès en el segle XXI : introducció a la pugna entre la creació i el mercat a través de cinc artistes destacats i les seves cotitzacions en les subhastes

En el relativament breu lapse de temps que suposen les tres darreres dècades, l'art contemporani xinès ha passat de ser pràcticament invisible i desconegut per al públic general, a ser present en un gran nombre d'escenaris a nivell internacional relacionats amb el món de l'art, sobre tot des de finals de la dècada dels noranta. El present TdR ha intentat apropar-se a qüestions com la imatge i les idees que sobre la RP Xina s'han transmès en l'última dècada a través de les obres o de les accions dels artistes xinesos contemporanis més exposats o cotitzats internacionalment i que viuen a la Xina, i a com s'ha arribat a inserir la producció artística d'aquests autors en el procés de globalització i hibridació de la cultura que estem vivint. Hem delimitat el camp de recerca, bàsicament a l'estudi de l'obra de cinc autors (Song Dong, Ai Weiwei, Zeng Fanzhi, Yue Minjun i Wang Qingsong) i a la seva presència en l'escena internacional de l'art contemporani a través de les subhastes de les dues cases més importants del món, Christie's i Sotheby's.
