Prevalência de Streptococcus pyogenes em orofaringe de crianças que freqüentam creches: estudo comparativo entre diferentes regiões do país

Trinta por cento das faringotonsilites agudas são de etiologia estreptocócica com potencial de complicações como a glomerulonefrite difusa aguda e febre reumática. Crianças de creches apresentam maior incidência destas infecções. OBJETIVO: Identificar e comparar a prevalência do Streptococcus pyogenes na orofaringe entre crianças que freqüentam creches e crianças não-institucionalizadas, em duas regiões do Brasil. CASUÍSTICA E MÉTODO: Estudo prospectivo com 200 crianças, provenientes da cidade de Porto Velho/RO e São Paulo/SP, em quatro grupos, freqüentadoras ou não de creches. Realizou-se swab de orofaringe e cultura para identificação do Streptococcus pyogenes. RESULTADOS: Prevalência de 8% e 2% entre as crianças de São Paulo que atendem a creches e do grupo controle, respectivamente, apresentando valor estatístico (p=0,02). Prevalência de 24% e 16% nos grupos de Porto Velho/RO que freqüentam creche e controle respectivamente, não caracterizando diferença estatisticamente significante (p=0,18). Observou-se diferença estatisticamente significante entre os grupos creche e controle de São Paulo/SP aos seus correspondentes de Porto Velho/RO (p < 0,01). CONCLUSÃO: Os resultados deste estudo nos permitem sugerir que freqüência em creches representa um fator de risco para a colonização de orofaringe pelo Streptococcus pyogenes, fato observado em populações distintas, porém com significância estatística em apenas uma das duas amostras.

Genetic divergence in cocoa progenies for backcrossing program to witches' broom disease resistance

Backcrossing has been little used in cacao breeding, particularly due to the long time required to transfer genes and recover the genetic background of the recurrent parent. The objective of this study was to select individuals, resulting from the backcross CEPEC-42 x SIC-19, genetically related to the recurrent parent SIC-19 by using RAPD molecular markers, among those with resistance to witches' broom. Of the 31 plants that clustered with SIC-19, 18 from the replanted material remained free of the disease in the field, with good vegetative aspect and, therefore can be used for backcross to reach the desired objective.

The decentralized social networking systems towards mobilizing actions of citizenship and solidarity against cancer

The goal of the present study is mapping the nature of possible contributions of participatory online platforms in citizen actions that may contribute in the fight against cancer and its associated consequences. These platforms are usually associated with entertainment: in that sense, we intent to test their validity in other domains such as health, as well as contribute to an expanded perception of their potential by their users. The research is based on the analysis of online solidarity networks, namely the ones residing on Facebook, Orkut and the blogosphere, that citizens have been gradually resorting to. The research is also based on the development of newer and more efficient solutions that provide the individual (directly or indirectly affected by issues of oncology) with the means to overcome feelings of impotence and fatality. In this article, we aim at summarizing the processes of usage of these decentralized, freer participatory platforms by citizens and institutions, while attempting to unravel existing hype and stigma; we also provide a first survey of the importance and the role of institutions in this kind of endeavor; lastly, we present a prototype, developed in the context of the present study, that is specifically dedicated to addressing oncology through social media. This prototype is already available online at www.talkingaboutcancer.org, however, still under development and testing. The main objective of this platform is to allow every citizen to freely build their network of contacts and information, according to their own individual and/ or collective needs and desires.

Program slicing by calculation

Program slicing is a well known family of techniques used to identify code fragments which depend on or are depended upon specific program entities. They are particularly useful in the areas of reverse engineering, program understanding, testing and software maintenance. Most slicing methods, usually oriented towards the imperative or object paradigms, are based on some sort of graph structure representing program dependencies. Slicing techniques amount, therefore, to (sophisticated) graph transversal algorithms. This paper proposes a completely different approach to the slicing problem for functional programs. Instead of extracting program information to build an underlying dependencies’ structure, we resort to standard program calculation strategies, based on the so-called Bird-Meertens formalism. The slicing criterion is specified either as a projection or a hiding function which, once composed with the original program, leads to the identification of the intended slice. Going through a number of examples, the paper suggests this approach may be an interesting, even if not completely general, alternative to slicing functional programs

Component identification through program slicing

This paper reports on the development of specific slicing techniques for functional programs and their use for the identification of possible coherent components from monolithic code. An associated tool is also introduced. This piece of research is part of a broader project on program understanding and re-engineering of legacy code supported by formal methods

Criminal Liability of Organizations, Corporations, Legal Persons, and Similar Entities on Law of Portuguese Cybercrime: A Brief Discussion on the Issue of Crimes of “False Information,” the “Damage on Other Programs or Computer Data,” the “Computer-Software Sabotage,” the “Illegitimate Access,” the “Unlawful Interception,” and “Illegitimate Reproduction of the Protected Program”

Abstract: in Portugal, and in much of the legal systems of Europe, «legal persons» are likely to be criminally responsibilities also for cybercrimes. Like for example the following crimes: «false information»; «damage on other programs or computer data»; «computer-software sabotage»; «illegitimate access»; «unlawful interception» and «illegitimate reproduction of protected program». However, in Portugal, have many exceptions. Exceptions to the «question of criminal liability» of «legal persons». Some «legal persons» can not be blamed for cybercrime. The legislature did not leave! These «legal persons» are v.g. the following («public entities»): legal persons under public law, which include the public business entities; entities utilities, regardless of ownership; or other legal persons exercising public powers. In other words, and again as an example, a Portuguese public university or a private concessionaire of a public service in Portugal, can not commit (in Portugal) any one of cybercrime pointed. Fair? Unfair. All laws should provide that all legal persons can commit cybercrimes. PS: resumo do artigo em inglês.

“Portugal, país de brandos costumes”?

Será? Um pouco da sua história e já no Séc. XX. Vamos, por momentos, esquecer as milhares de guerras que tivemos antes, a tortura pública ou a inquisição ou até alguns massacres e genocídios que fizemos aquando das chamadas descobertas. Em alguns casos, pois os portugueses foram bem mais brandos do que outros “descobridores”, é certo, misturando-se inclusive com os nativos. Os Portugueses, “esse Povo de brandos costumes…”. Abstract: Will be? A little of its history and in the century. XX. Let's for a moment forget the thousands of wars we had before, public torture or inquisition or even some massacres and genocides we did during the calls findings. In some cases, because the Portuguese were far more lenient than others "discoverers", of course, including blending with the natives. The Portuguese, "People of this mild manners ...".

Da letargia ao realento: notas sobre o ensino de graduação em administração pública no Brasil no entremeio da crise do Estado e da redemocratização no país (1983-94)

Considerando o entremeio da crise do Estado e da redemocratização no Brasil, este artigo volta-se para uma descrição e análise dos fatos e circunstâncias que marcaram o ensino de graduação em administração pública no Brasil no período 1983-94, considerado pelos autores como um dos ciclos (ou estágios de construção) desta formação acadêmica. Metodologicamente, o artigo faz a revisão bibliográfica daquelas obras que abordam direta e indiretamente o tema, incluindo a revisita de suas fontes; analisa as leis e pareceres existentes sobre o ensino de graduação em administração pública nesse intervalo de tempo, bem como utiliza-se de algumas entrevistas semiestruturadas com acadêmicos que vivenciaram tal período. No que se refere aos resultados, observa-se que o período 1983-94, diferentemente do 1ºciclo (1952-65) e do 2ºciclo (1966-82), quando a formação acadêmica em administração pública tinha uma identidade - aderente à concepção (e ao projeto) de Estado e aos contornos (e à produção) do campo do saber da administração pública -, tendo na Ebap/FGV um case modelar, foi um estágio de construção problemático, refletindo a crise do Estado dos anos 1980 e, igualmente, a crise (ou descontinuidade) paradigmática do campo do saber em administração pública no Brasil em tal época.

Sustainable Tourism and Eradication of Poverty (Step): impact assessment of a tourism development program in Brazil

This paper aims to evaluate the social impacts of the Tourism Development Program (Prodetur) in the northeastern town of Porto Seguro, Bahia, Brazil. The method used is based on the difference in difference technique applied to the 1991 and 2000 Census microdata. The results suggest social advances following from poverty relief based on income - where the benefits are distributed, generally, in a relatively equal manner between the native and migrant population. There is a relative deterioration in the sanitary situation, which consists of a very serious problem in the mid- and long-term, whose costs are mostly borne by the native population. Therefore, maintaining the natural capital is the main aspect that distances Porto Seguro’s tourism supply from the concept of sustainability. The article also relies on difference in difference estimators to assess the impacts of local public policies related to the sector.

A supervised versus home-based program effects on liver transplanted familial amyloidotic polyneuropathy patients: walking, fatigue and quality of life

Purpose: To evaluate the effects of a six months exercise training program on walking capacity, fatigue and health related quality of life (HRQL). Relevance: Familial amyloidotic polyneuropathy disease (FAP) is an autossomic neurodegenerative disease, related with systemic deposition of amyloidal fibre mainly on peripheral nervous system and mainly produced in the liver. FAP often results in severe functional limitations. Liver transplantation is used as the only therapy so far, that stop the progression of some aspects of this disease. Transplantation requires aggressive medication which impairs muscle metabolism and associated to surgery process and previous possible functional impairments, could lead to serious deconditioning. Reports of fatigue are common feature in transplanted patients. The effect of supervised or home-based exercise training programs in FAP patients after a liver transplant (FAPTX) is currently unknown.

Effects of an exercise training program in physical condition after liver transplantation in familial amyloidotic polyneuropathy: a case report

Introduction: Familial amyloidotic polyneuropathy (FAP) is a neurodegenerative disease that leads to sensory and motor polyneuropathies as well as functional limitations. So far, liver transplantation is the only treatment for FAP because the mutated protein causing the disease is mainly produced in the liver. With the increasing survival of transplant recipients, functional and cardiovascular problems as consequences of immunosuppressant side effects are increasing associated with sedentary lifestyles and/or retransplantation status. We sought to analyze the impact of exercise training programs on 1 FAP patient’s course long-term after liver transplantation. Methodology. A FAP patient (female; 49 years of age; body mass index 18.8 kg/m2) underwent a liver transplantation 133 months before assessment. She was assessed for body composition, isometric quadriceps muscle strength, functional capacity, fatigue, and levels of physical activity before and after a 6-month period of combined exercise training. Results: After the exercise training program, almost all variables were improved, namely, total body skeletal muscle mass, proximal femoral bone mineral density, quadriceps strength, maximal oxygen consumption on 6 minutes walk test (6mwt) or VO2peak, total ventilation on 6mwt, and fatigue. The improvement in distance on 6mwt (69.2 m) was clinically significant. Preintervention the levels of physical activity were below international recommendations for health; after the program they achieved the recommendations. Conclusion: The results showed an improvement in functional capacity with a decrease in future disability risk associated with a better lifestyle with respect to physical activity levels in 1 patient.

Intermittent claudication and physical exercise: effectiveness of a home-based program

Peripheral arterial disease (PAD) as a high incidence in general population and 12% to 20% of population with more than 60 years has already clinical symptoms, such as intermittent claudication (IC), pain, loss of strength and functional incapacity. There are already some studies who refer the possible positive effects of physical exercise in functional consequences of PAD.

A supervised versus home-based program effects on liver transplanted familial amyloidotic polyneuropathy patients: walking, fatigue and quality of life

Familial amyloidotic polyneuropathy is a systemic deposition of amyloidal fibre mainly on peripheral nervous system (but also in other systems like heart, gastrointestinal tract, kidneys, etc) and mainly produced in the liver. Purpose of this study: to evaluate the effects of a six months exercise training program(supervised or home-based) on walking capacity, fatigue and health related quality of life (HRQL) on Familial Amyloidotic Polyneuropathy patients submitted to a liver transplant.
