O Agronegócio e o problema do trabalho infantil

This article attempts to identify and analyze the motives that led several sectors of agro-business to engage in the struggle for the eradication of child labor in Brazil, as launched by international organizations for the defense of children's and adolescents' rights. It is our hypothesis that economic globalization and the internationalization of children's rights have given visibility to the problem of child labor, thus demanding the mobilization of entrepreneurial sectors linked to agro-business productive chains in Brazil. The article is divided into four inter-related sections. In the first one, we attempt to provide evidence for the interference of social and labor problems within the ambit of the economic activities of the agro-business sector, within the current context of globalization. This is followed by a study of major UN, UNICEF and ILO investments to internalize children's rights and policies to combat child labor, giving salience to their repercussions in Brazil. In the third section, we analyze strategies adopted by firms linked to agro-business with the purpose of avoiding the use of child labor within their productive chains. Finally, we seek to understand the motivations that have led agro-businessmen to take part in the struggle against child labor. We conclude that firms linked to agro-business took up the project of combating child labor in virtue of the internationalization of children and adolescents' rights, the inclusion of social issues in international markets, the intensification of the fiscalization of public power, the growth of action around entrepreneurial social responsibility and increased consumer consciousness.

Protein-energy status and 15N-glycine kinetic study of child a cirrhotic patients fed low- to high-protein energy diets

In five male cirrhotic patients (Child A) and in four age- and sex-matched healthy control subjects, whole-body protein turnover was measured using a single oral dose of N-15-glycine as a tracer and urinary ammonia as end product. Subjects were studied in the fasting and feeding state, with different levels of protein and energy intake. The patients were underweight and presented lower plasma transthyretin and retinol-binding protein levels. When compared with controls, the kinetic studies showed patients to be hypometabolic in the fasting (Do) state and with the control diet [D-1 = (0.85 g of protein/154 kJ). kg(-1). day(-1)]. However, when corrected by body weight, the kinetic differences between groups disappeared, whereas the N-retention in the feeding state showed better results for the patients due mainly to their efficient breakdown decrease. When fed high-level protein or energy diets [D-2 = (0.9 g protein/195 kJ) and D-3 = (1.56 g protein/158 kJ). kg(-1). day(-1)], the patients showed D-0 = D-1 = D-2 < D-3 for N-flux and (D-0 = D-1) < D-3 (D-2 is intermediary) for protein synthesis. Thus, the present data suggest that the remaining mass of the undernourished mild cirrhotic patients has fairly good protein synthesis activity and also that protein, rather than energy intake, would be the limiting factor for increasing their whole-body protein synthesis.

Challenges to the treatment and new perspectives for the eradication of helicobacter pylori

Helicobacter pylori (H. pylori) is one of the leading causes of gastric diseases such as chronic gastritis, peptic ulcer, and gastric adenocarcinoma. The current treatment of H. pylori infection with antibiotics and proton pump inhibitors has several limitations, including poor adherence and intrinsic patient-related factors, drug resistance, and the absence of adequate treatments. This review summarizes the current therapeutic approaches to eradicating H. pylori, the difficulties associated with its treatment, and several new perspectives aimed at improving existing treatment strategies.

Eradication of Salmonella Typhimurium in broiler chicks by combined use of P22 bacteriophage and probiotic

It has been reported that the phage therapy is effective in controlling the number of colony-forming unit (CFU) of Salmonella spp. in chicken gut. This paper describes the protective effect of phage and Lactobacilli administration on Salmonella infection in 1-day-old chicks. We administered the bacteriophage P22 in a single dose and a probiotic mixture of four species of bacteriocin-producing Lactobacillus once a day for one week. Samples were analyzed every 48 hours, and intestinal eradication of S. Typhimurium was confirmed after treatments. We observed an increase in the size of duodenal villi and cecal crypts, as well as an increase in body weight in groups that received daily doses of Lactobacilli. This study confirms the efficiency of bacteriophage therapy in controlling salmonellosis in chicks and the beneficial effect of Lactobacilli mixtures in the weight gain of the birds.

In vitro Activity of Daptomycin, Linezolid and Rifampicin on Staphylococcus epidermidis Biofilms

Owing to their massive use, Staphylococcus epidermidis has recently developed significant resistance to several antibiotics, and became one of the leading causes of hospital-acquired infections. Current antibiotics are typically ineffective in the eradication of bacteria in biofilm-associated persistent infections. Accordingly, the paucity of effective treatment against cells in this mode of growth is a key factor that potentiates the need for new agents active in the prevention or eradication of biofilms. Daptomycin and linezolid belong to the novel antibiotic therapies that are active against gram-positive cocci. on the other hand, rifampicin has been shown to be one of the most potent, prevalent antibiotics against S. epidermidis biofilms. Therefore, the main aim of this study was to study the susceptibility of S. epidermidis biofilm cells to the two newer antimicrobial agents previously mentioned, and compare the results obtained with the antimicrobial effect of rifampicin, widely used in the prevention/treatment of indwelling medical device infections. To this end the in vitro activities of daptomycin, linezolid, and rifampicin on S. epidermidis biofilms were accessed, using these antibiotics at MIC and peak serum concentrations. The results demonstrated that at MIC concentration, rifampicin was the most effective antibiotic tested. At peak serum concentration, both strains demonstrated similar susceptibility to rifampicin and daptomycin, with colony-forming units (CFUs) reductions of approximately 3-4 log(10), with a slightly lower response to linezolid, which was also more strain dependent. However, considering all the parameters studied, daptomycin was considered the most effective antibiotic tested, demonstrating an excellent in vitro activity against S. epidermidis biofilm cells. In conclusion, this antibiotic can be strongly considered as an acceptable therapeutic option for S. epidermidis biofilm-associated infections and can represent a potential alternative to rifampicin in serious infections where rifampicin resistance becomes prevalent.

Saúde do trabalhador no SUS: desafios e perspectivas frente à precarização do trabalho

Refletir sobre o campo saúde do(a) trabalhador(a) é o objetivo deste estudo. Busca-se sublinhar o significado das condições de trabalho para o ser humano do ponto de vista da saúde. A premissa não é quantificar, mas inferir que as condições de trabalho podem gerar danos à saúde, mas nem sempre apresentam de imediato a sua relação com o trabalho. São discutidas, a partir da abordagem qualitativa, três situações, as quais contemplam os trabalhos rural, informal e infantil e, como resultado, verifica-se a contradição da categoria trabalho, que, se por um lado é sinônimo de sociabilidade, por outro, contraditoriamente, constitui-se em mecanismo de exclusão social na medida em que é realizado sem o reconhecimento dos direitos sociais e trabalhistas. Verifica-se a expansão de formas de trabalho sem regulamentação, tais como o domiciliar e o familiar e os realizados em locais como a rua e o lixo. Encerra-se a reflexão com destaque ao papel do Sistema Único de Saúde (SUS) na assistência integral à saúde dos(as) trabalhadores(as) e ao desafio de atuar na perspectiva de prevenção e promoção da saúde do trabalhador de modo integrado e articulado aos demais órgãos públicos que atuam nesta área.

Alien fishes in lakes of the Doce river basin (Brazil): Range, new occurrences and conservation of native communities

The present study shows the distribution of alien fish species in tropical lakes in the middle Doce river basin, southeastern Brazil, obtained from a rapid assessment program. The causes for their introductions were sport-fishing improvement in some specific lakes and aquaculture in the studied basin. Presently, these species have a wide distribution occurring in 41 of the 54 lakes studied, representing an actual threat to regional native fish community. The natural connection among lakes and streams during the rainy season and the dispersal mediated by local people are the main invasion agents for alien fishes. The success of these invaders is probably due to absence of pre-existing effective competitors or top-predators in the invaded communities. We consider that the eradication of alien fishes by means of the available management tools may be very difficult due to the large number of lakes invaded and to the wide spectrum of lake conditions and resources exploited by these alien species. We recommend the use of environmental education as a tool to stop the human-mediated dispersion of aliens and to improve conservation of native fish community in lakes where these alien species are not present yet. © 2004 Instituto de Ciências Biológicas - UFMG.

The formation of the professionals for the timber industrial sector of the civil construction

The common point between the two forms of production of the wood-based sector in Brazil, one practically manufacturing and the other high technology, is in the qualification of the of the labor. In both cases, the professionals are being formed directly in the productive line and rarely with qualification in the academic area. There is not a public political education for the qualification of the labor, and the work market that does not demand qualified professionals, contributes for the sector stagnation. So, in order to excel the socio-cultural barriers in relation to the use of wood in the buildings, new attitudes are necessary in the teaching of the contents of the curricular programs, mainly, in formation of the architect and civil engineering.
