O público e o privado na condução da gestão educacional pública brasileira

O texto de dissertação intitulado “O Público e o Privado na condução da Gestão Educacional Pública Brasileira” apresenta como objeto de estudo a gestão da educação pública no contexto do Plano de Ações Articuladas (PAR), considerando que tal instrumento é definido atualmente pelo Estado como o norteador das políticas educacionais e pressupomos que nele também se articulam interesses entre os representantes dos setores público e privado. O objetivo geral do estudo é analisar como a relação entre os setores público e privado se apresenta no contexto do Plano de Ações Articuladas. Para a fundamentação teórico-metodológica deste trabalho, consideramos importante o aporte com base no materialismo histórico-dialético, pois se mostra mais adequado à medida que possibilita uma visão crítica sobre a realidade analisada capturando suas contradições, em vista de que pretendemos trabalhar com o conhecimento da realidade documental que envolve a trama em torno do público e do privado na construção da gestão educacional pública. A pesquisa teve como metodologia a análise documental que foi construída num entrelaçamento da apreciação das autoras desta dissertação e à luz de alguns teóricos como Adrião e Camargo (2007), Cury (2013), Pinheiro (2005), Pino (2008), Saviani (2008, 2014), Severino (2014), Vieira (2007, 2010), Vieira e Vidal (2014) os quais tecem observações e fazem interpretações dos documentos que servem de referência a este estudo. De modo geral, os resultados da pesquisa mostraram que as relações e influências dos organismos internacionais são determinantes na formulação das políticas educacionais e das diretrizes e propostas de gestão educacional no contexto brasileiro, no final do século XX e início do século XXI. Mostraram, também, que a disputa entre os setores público e privado se ampliaram e se intensificaram no que concerne à organização da educação básica brasileira, no contexto dos marcos legais que a estruturam. E por fim, a relação entre o público e o privado, por meio do Plano de Ações Articuladas, se configura no âmbito de uma relação de interesses onde predomina o interesse individual de empresários, do qual, a lógica privada é dominante, em detrimento do interesse coletivo da sociedade.

Síndrome metabólica e fatores associados em populações da Amazônia oriental brasileira: um estudo transversal

Introdução: a síndrome metabólica (SM) desempenha papel fundamental na origem das doenças cardiovasculares. Estudos sobre a SM no Brasil ainda são recentes, e em regiões mais isoladas como na Amazônia, o seu comportamento epidemiológico ainda é desconhecido. O estudo objetivou estimar a prevalência da SM e fatores associados em adultos da Amazônia Brasileira. Métodos: realizou-se no período de 2012 a 2013 um estudo transversal de base populacional, com a participação de 787 adultos selecionados aleatoriamente da área urbana de quatro cidades do estado do Pará, Amazônia Oriental Brasileira. Os participantes foram submetidos a avaliação antropométrica, laboratorial e interrogados sobre o estilo de vida. A síndrome metabólica foi definida pelo critério clínico harmonizado - Joint Interim Statement, sendo utilizada a regressão logística múltipla para verificar o potencial de associação dos fatores de risco com a presença da SM. Resultados: A prevalência geral da SM foi de 34,1% (IC 95%= 30,8-37,4), aumentando linearmente com aumento do índice de massa corporal e idade. A partir da faixa etária de 40-49 anos a SM atingiu aproximadamente metade das mulheres (46,0%), enquanto que os homens só experimentaram prevalência similar na quinta década de vida (43,3%). O HDL-c baixo (64,4%) e a obesidade abdominal (58,9%) são mais elevadas nas mulheres (p < 0,0001), já para os homens, a pressão arterial elevada é significativamente superior (p < 0,0009). Foram mais propensos a ter SM quem estava na faixa etaria de 40–59 anos (odds ratio [OR]= 3,35 [IC 95%= 2,30-4,90]); ou ≥ 60 anos (OR= 5,80 [3,63-9,27]); ou com sobrepeso (OR= 4,17 [2,77-6,29]); ou obeso (OR= 8,82 [5,56-13,98]). Conclusão: A população estudada experimenta elevado risco cardiometabólico, nescessitando de esforços governamentais para o controle da SM e dos fatores de risco relacionados, especialmente da obesidade.

Rehabilitation of the Maxillary Arch After Bone Graft Using Immediate Loading With Implant-Supported Fixed Restoration

Moderate and controlled loading environments support or enhance osteogenesis, and, consequently, a high degree of bone-to-implant contact can be acquired. This is because when osteoprogenitor cells are exposed to limited physical deformation, their differentiation into osteoblasts is enhanced. Then, some range of microstrain is considered advantageous for bone ingrowth and osseointegration. The primary stability has been considered one of the main clinical means of controlling micromotion between the implant and the forming interfacial tissue, which helps to establish the proper mechanical environment for osteogenesis. Based on the biological aspects of immediate loading (IL), the objective of this study is to present a clinical case of maxillary arch rehabilitation using immediate loading with implant-supported fixed restoration after bone graft. Ten dental implants were placed in the maxilla 6 months after the autogenous bone graft, removed from the mandible (bilateral oblique line and chin), followed by the installation of an immediate-load fixed cross-arch implant-supported restoration because primary stability was reached for 8 implants. In addition, instructions about masticatory function and how it is related to interfacial micromotion were addressed and emphasized to the patient. The reasons for the IL were further avoidance of an interim healing phase, a potential reduction in the number of clinical interventions for the patient, and aesthetic reasons. After monitoring the rehabilitation for 8 years, the authors can conclude that maxillary IL can be performed followed by a well-established treatment planning based on computed tomography, providing immediate esthetics and function to the patient even when autogenous bone graft was previously performed in the maxilla.

Mini-implants as provisional anchorage for the replacement of missing anterior teeth: A clinical report

This clinical report describes an adult patient referred for orthodontic treatment with mini-implants as anchorage to correct the root angulation of maxillary lateral incisors. The purpose of this report was to demonstrate the versatility of mini-implants placed in a vertical direction in esthetic areas. During orthodontic treatment, some aspects must be observed to preserve the interim restoration against the occlusal loads to avoid screw fracture. A fixed appliance was placed to correct the position of the maxillary anterior teeth and to complete the treatment. Acceptable esthetics and function were achieved.

Validity and behaviour of tropospheric gradients estimated by GPS in Corsica

Estimation of tropospheric gradients in GNSS data processing is a well-known technique to improve positioning (e.g. Bar-Sever et al., 1998; Chen and Herring, 1997). More recently, several authors also focused on the estimation of such parameters for meteorological studies and demonstrated their potential benefits (e.g. Champollion et al., 2004). Today, they are routinely estimated by several global and regional GNSS analysis centres but they are still not yet used for operational meteorology.This paper discusses the physical meaning of tropospheric gradients estimated from GPS observations recorded in 2011 by 13 permanent stations located in Corsica Island (a French Island in the western part of Italy). Corsica Island is a particularly interesting location for such study as it presents a significant environmental contrast between the continent and the sea, as well as a steep topography.Therefore, we estimated Zenith Total Delay (ZTD) and tropospheric gradients using two software: GAMIT/GLOBK (GAMIT version 10.5) and GIPSY-OASIS II version 6.1. Our results are then compared to radiosonde observations and to the IGS final troposphere products. For all stations we found a good agreement between the ZWD estimated by the two software (the mean of the ZWD differences is 1 mm with a standard deviation of 6 mm) but the tropospheric gradients are in less good agreement (the mean of the gradient differences is 0.1 mm with a standard deviation of 0.7 mm), despite the differences in the processing strategy (double-differences for GAMIT/GLOBK versus zero-difference for GIPSY-OASIS).We also observe that gradient amplitudes are correlated with the seasonal behaviour of the humidity. Like ZWD estimates, they are larger in summer than in winter. Their directions are stable over the time but not correlated with the IWV anomaly observed by ERA-Interim. Tropospheric gradients observed at many sites always point to inland throughout the year. These preferred directions are almost opposite to the largest slope of the local topography as derived from the world Digital Elevation Model ASTER GDEM v2. These first results give a physical meaning to gradients but the origin of such directions need further investigations.

Planejamento em reabilitação oral: restabelecimento da relação intermaxilar por meio de prótese provisória overlay

The present article describes the treatment planning and fabrication of overlay denture to restore the jaw relationship in a partial edentulous patient with bruxism. A male patient, 51 years old, was referred to the oral rehabilitation clinic complaining about the chewing and aesthetic. The occlusal surface of the superior teeth presented severe wear. The fabrication of an interim overlay denture to restore the jaw relationship was planned. The overlay had metallic projections and covered the occlusal surface of superior teeth. After overlay insertion both function and aesthetic of the patient were recovered. It was concluded that the use of overlay improved the physiological normal position of the jaw and could provide a favorable prognosis for a definitive oral rehabilitation with implant-supported fixed denture.

Pertuzumab plus Trastuzumab plus Docetaxel for Metastatic Breast Cancer

BACKGROUND The anti-human epidermal growth factor receptor 2 (HER2) humanized monoclonal antibody trastuzumab improves the outcome in patients with HER2-positive metastatic breast cancer. However, most cases of advanced disease eventually progress. Pertuzumab, an anti-HER2 humanized monoclonal antibody that inhibits receptor dimerization, has a mechanism of action that is complementary to that of trastuzumab, and combination therapy with the two antibodies has shown promising activity and an acceptable safety profile in phase 2 studies involving patients with HER2-positive breast cancer. METHODS We randomly assigned 808 patients with HER2-positive metastatic breast cancer to receive placebo plus trastuzumab plus docetaxel (control group) or pertuzumab plus trastuzumab plus docetaxel (pertuzumab group) as first-line treatment until the time of disease progression or the development of toxic effects that could not be effectively managed. The primary end point was independently assessed progression-free survival. Secondary end points included overall survival, progression-free survival as assessed by the investigator, the objective response rate, and safety. RESULTS The median progression-free survival was 12.4 months in the control group, as compared with 18.5 months in the pertuzumab group (hazard ratio for progression or death, 0.62; 95% confidence interval, 0.51 to 0.75; P<0.001). The interim analysis of overall survival showed a strong trend in favor of pertuzumab plus trastuzumab plus docetaxel. The safety profile was generally similar in the two groups, with no increase in left ventricular systolic dysfunction; the rates of febrile neutropenia and diarrhea of grade 3 or above were higher in the pertuzumab group than in the control group. CONCLUSIONS The combination of pertuzumab plus trastuzumab plus docetaxel, as compared with placebo plus trastuzumab plus docetaxel, when used as first-line treatment for HER2-positive metastatic breast cancer, significantly prolonged progression-free survival, with no increase in cardiac toxic effects.

Prevalence of metabolic syndrome in elderly Japanese-Brazilians

Background: Prevalence of individuals with a high cardiovascular risk is elevated in elderly populations. Although metabolic syndrome (MS) increases cardiovascular risk, information is scarce on the prevalence of MS in the elderly. In this study we assessed MS prevalence in a population of elderly Japanese-Brazilians using different MS definitions according to waist circumference cutoff values. Material/Methods: We studied 339 elderly subjects, 44.8% males, aged between 60 to 88 years (70.1 +/- 6.8). MS was defined according to criteria proposed by the Joint Interim Statement in 2009. As waist circumference cutoff point values remain controversial for Asian and Japanese populations, we employed 3 different cutoffs that are commonly used in Japanese epidemiological studies: 1) >90 cm for men and >80 cm for women; 2) >85 cm for men and >90 cm for women; 3) >85 cm for men and >80 cm for women. Results: MS prevalence ranged from 59.9% to 65.8% according to the different definitions. We observed 90% concordance and no statistical difference (p>0.05) in MS prevalence between the 3 definitions. MS diagnosis according to all 3 cutoff values was found in 55.8% of our population, while in only 34.2% was MS discarded by all cutoffs. The prevalence of altered MS components was as follows: arterial blood pressure 82%, fasting glycemia 65.8%, triglyceride 43.4%, and HDL-C levels 36.9%. Conclusions: Elderly Japanese-Brazilians present high metabolic syndrome prevalence independent of waist circumference cutoff values. Concordance between the 3 definitions is high, suggesting that all 3 cutoff values yield similar metabolic syndrome prevalence values in this population.

The impact of medical education and networking on the outcome of leukemia treatment in developing countries. The experience of International Consortium on Acute Promyelocytic Leukemia (IC-APL)

Objectives: Several clinical trials conducted in Europe and US reported favorable outcomes of patients with APL treated with the combination of all trans retinoic acid (ATRA) and anthracyclines. Nevertheless, the results observed in developing countries with the same regimen was poorer, mainly due to high early mortality mainly due bleeding. The International Consortium on Acute Promyelocytic Leukemia (IC-APL) is an initiative of the International Members Committee of the ASH and the project aims to reduce this gap through the establishment of international network, which was launched in Brazil, Mexico and Uruguay. Methods: The IC-APL treatment protocol is similar to the PETHEMA 2005, but changing idarubicin to daunorubicin. All patients with a suspected diagnosis of APL were immediately started on ATRA, while bone marrow samples were shipped to a national central lab where genetic verification of the diagnosis was performed. The immunofluorescence using an anti-PML antibody allowed a rapid confirmation of the diagnosis and, the importance of supportive measures was reinforced. Results: The interim analysis of 97 patients enrolled in the IC-APL protocol showed that complete remission (CR) rate was 83% and the 2-year overall survival and disease-free survival were 80% and 90%, respectively. Of note, the early mortality rate was reduced to 7.5%. Discussion: The results of IC-APL demonstrate the impact of educational programs and networking on the improvement of the leukemia treatment outcome in developing countries.

Análise climatológica da precipitação e do transporte de umidade na região da ZCAS através da nova geração de reanálises

O conhecimento do desempenho das reanálises e dos erros associados a elas apresenta um papel fundamental na compreensão dos processos físicos que ocorrem na atmosfera. Este trabalho tem por objetivo documentar as principais características da precipitação associada à Zona de Convergência do Atlântico Sul (ZCAS), baseado em seis conjuntos de reanálises atmosféricas (MERRA, ERA-Interim, ERA-40, NCEP 1, NCEP 2 e NCEP CFSR) e cinco conjuntos de produtos observados de precipitação (SALDAS, CPC, CMAP, GPCP e GLDAS). Através destes dados também foi analisado o transporte de umidade sobre a região da ZCAS, para os anos de 1979 a 2007. Em resumo, este trabalho evidencia o avanço das novas reanálises na tentativa de representar de forma mais adequada a variável precipitação acumulada. Os diagramas de Taylor mostram que os produtos de precipitação estão bem correlacionados com o ponto de referência (CPC), com coeficientes entre 0,6 e 0,9. Somente a reanálise do NCEP CFSR possui correlações próximas as dos produtos de precipitação. Os conjuntos mais antigos de reanálises apresentam correlações menores, abaixo de 0,6. O Oceano Atlântico é a fonte principal do fluxo de umidade para a direção da ZCAS, que diminui na direção do continente. Na Região SE do Brasil, a topografia tem um papel importante para a convergência de umidade. Já na parte noroeste da ZCAS, este fator deve estar associado a processos termodinâmicos.

Bioremediation of PAHs - Limitations and soultions

Introduction 1.1 Occurrence of polycyclic aromatic hydrocarbons (PAH) in the environment Worldwide industrial and agricultural developments have released a large number of natural and synthetic hazardous compounds into the environment due to careless waste disposal, illegal waste dumping and accidental spills. As a result, there are numerous sites in the world that require cleanup of soils and groundwater. Polycyclic aromatic hydrocarbons (PAHs) are one of the major groups of these contaminants (Da Silva et al., 2003). PAHs constitute a diverse class of organic compounds consisting of two or more aromatic rings with various structural configurations (Prabhu and Phale, 2003). Being a derivative of benzene, PAHs are thermodynamically stable. In addition, these chemicals tend to adhere to particle surfaces, such as soils, because of their low water solubility and strong hydrophobicity, and this results in greater persistence under natural conditions. This persistence coupled with their potential carcinogenicity makes PAHs problematic environmental contaminants (Cerniglia, 1992; Sutherland, 1992). PAHs are widely found in high concentrations at many industrial sites, particularly those associated with petroleum, gas production and wood preserving industries (Wilson and Jones, 1993). 1.2 Remediation technologies Conventional techniques used for the remediation of soil polluted with organic contaminants include excavation of the contaminated soil and disposal to a landfill or capping - containment - of the contaminated areas of a site. These methods have some drawbacks. The first method simply moves the contamination elsewhere and may create significant risks in the excavation, handling and transport of hazardous material. Additionally, it is very difficult and increasingly expensive to find new landfill sites for the final disposal of the material. The cap and containment method is only an interim solution since the contamination remains on site, requiring monitoring and maintenance of the isolation barriers long into the future, with all the associated costs and potential liability. A better approach than these traditional methods is to completely destroy the pollutants, if possible, or transform them into harmless substances. Some technologies that have been used are high-temperature incineration and various types of chemical decomposition (for example, base-catalyzed dechlorination, UV oxidation). However, these methods have significant disadvantages, principally their technological complexity, high cost , and the lack of public acceptance. Bioremediation, on the contrast, is a promising option for the complete removal and destruction of contaminants. 1.3 Bioremediation of PAH contaminated soil & groundwater Bioremediation is the use of living organisms, primarily microorganisms, to degrade or detoxify hazardous wastes into harmless substances such as carbon dioxide, water and cell biomass Most PAHs are biodegradable unter natural conditions (Da Silva et al., 2003; Meysami and Baheri, 2003) and bioremediation for cleanup of PAH wastes has been extensively studied at both laboratory and commercial levels- It has been implemented at a number of contaminated sites, including the cleanup of the Exxon Valdez oil spill in Prince William Sound, Alaska in 1989, the Mega Borg spill off the Texas coast in 1990 and the Burgan Oil Field, Kuwait in 1994 (Purwaningsih, 2002). Different strategies for PAH bioremediation, such as in situ , ex situ or on site bioremediation were developed in recent years. In situ bioremediation is a technique that is applied to soil and groundwater at the site without removing the contaminated soil or groundwater, based on the provision of optimum conditions for microbiological contaminant breakdown.. Ex situ bioremediation of PAHs, on the other hand, is a technique applied to soil and groundwater which has been removed from the site via excavation (soil) or pumping (water). Hazardous contaminants are converted in controlled bioreactors into harmless compounds in an efficient manner. 1.4 Bioavailability of PAH in the subsurface Frequently, PAH contamination in the environment is occurs as contaminants that are sorbed onto soilparticles rather than in phase (NAPL, non aqueous phase liquids). It is known that the biodegradation rate of most PAHs sorbed onto soil is far lower than rates measured in solution cultures of microorganisms with pure solid pollutants (Alexander and Scow, 1989; Hamaker, 1972). It is generally believed that only that fraction of PAHs dissolved in the solution can be metabolized by microorganisms in soil. The amount of contaminant that can be readily taken up and degraded by microorganisms is defined as bioavailability (Bosma et al., 1997; Maier, 2000). Two phenomena have been suggested to cause the low bioavailability of PAHs in soil (Danielsson, 2000). The first one is strong adsorption of the contaminants to the soil constituents which then leads to very slow release rates of contaminants to the aqueous phase. Sorption is often well correlated with soil organic matter content (Means, 1980) and significantly reduces biodegradation (Manilal and Alexander, 1991). The second phenomenon is slow mass transfer of pollutants, such as pore diffusion in the soil aggregates or diffusion in the organic matter in the soil. The complex set of these physical, chemical and biological processes is schematically illustrated in Figure 1. As shown in Figure 1, biodegradation processes are taking place in the soil solution while diffusion processes occur in the narrow pores in and between soil aggregates (Danielsson, 2000). Seemingly contradictory studies can be found in the literature that indicate the rate and final extent of metabolism may be either lower or higher for sorbed PAHs by soil than those for pure PAHs (Van Loosdrecht et al., 1990). These contrasting results demonstrate that the bioavailability of organic contaminants sorbed onto soil is far from being well understood. Besides bioavailability, there are several other factors influencing the rate and extent of biodegradation of PAHs in soil including microbial population characteristics, physical and chemical properties of PAHs and environmental factors (temperature, moisture, pH, degree of contamination). Figure 1: Schematic diagram showing possible rate-limiting processes during bioremediation of hydrophobic organic contaminants in a contaminated soil-water system (not to scale) (Danielsson, 2000). 1.5 Increasing the bioavailability of PAH in soil Attempts to improve the biodegradation of PAHs in soil by increasing their bioavailability include the use of surfactants , solvents or solubility enhancers.. However, introduction of synthetic surfactant may result in the addition of one more pollutant. (Wang and Brusseau, 1993).A study conducted by Mulder et al. showed that the introduction of hydropropyl-ß-cyclodextrin (HPCD), a well-known PAH solubility enhancer, significantly increased the solubilization of PAHs although it did not improve the biodegradation rate of PAHs (Mulder et al., 1998), indicating that further research is required in order to develop a feasible and efficient remediation method. Enhancing the extent of PAHs mass transfer from the soil phase to the liquid might prove an efficient and environmentally low-risk alternative way of addressing the problem of slow PAH biodegradation in soil.

Effetti clinici e biologici della terapia epigenetica nelle sindromi mielodisplastiche a basso rischio

Background: Nucleoside 5-Azacitidine (5-Aza) in high risk MDS patients (pts) at a dose of 75mg/mq/day subcutaneously for 7 days, every 28 days, induces high hematologic response rates (hematologic improvement (HI) 50-60%, complete remission (CR) 10-30%) and prolongation of survival (at 2 years 50,8%). Aim: The role of 5-Aza in low-risk MDS patients is not well defined but its use in the earlier phases of disease could be more effective and useful to control the expansion of MDS clone and disease progression. In our phase II, prospective, multicentric trial a low-dose schedule of 5-Aza (75 mg/mq daily for 5 consecutive days every 28 days) was given to low-risk MDS pts in order to evaluate its efficacy and tolerability and to identify biological markers to predict the response. Methods: From September 2008 to February 2010, 34 patients were enrolled into the study. Fifteen patients had refractory anemia (RA), 5 patients refractory anemia with ringed sideroblasts (RARS), 7 patients refractory cytopenia with multilineage dysplasia (RCMD) and 7 patients refractory anemia with excess blasts-1 (RAEB-1). All patients failed previously EPO therapy and were in chronic red blood cell (RBC) supportive care with a median transfusions requirement of 4 units/monthly. The response treatment criteria was according to IWG 2006. Results: At present time 31 out of 34 pts are evaluable: 12/31 pts (39%) completed the treatment plan (8 courses), 7/31 pts (22%) performed the first 4 courses, 8/31 (26%) made 1 to 3 courses and 4/31 (13%) died during the treatment period. Out of 12 pts who completed the 8 courses of therapy 10 (83%) obtained an HI, 2/12 (17%) maintained a stable disease. Out of 10 pts who obtained HI, 4 pts (40%) achieved a CR. Generally the drug was very well tolerated. The most commonly reported hematologic toxicities were neutropenia (55%) and thrombocytopenia (19%) but they were transitory and usually no delay of treatment was necessary. 2/4 pts died early after the 1th cycle for septic shock and gastrointestinal hemorrage respectively whereas 2/4 pts died in a condition of stable disease after the 4th cycle for pneumonia and respiratory distress. Samples for biologic studies have been collected from the pts before starting the therapy and at the end of 4th and 8th course. Preliminary data on the lipid signalling pathways suggested a direct correlation between PI-PLC-β1 gene expression and 5-Aza responsiveness. Conclusion: Interim analysis of our study based on the small number of cases who completed the treatment program, shows that 83% of pts obtain an HI and 40% obtain a CR. 4 patients died during the treatment and even if the causes were reported as no related to the therapy it has been considered that caution has to be reserved in given 5-Aza in these pts who are elderly and frail. Preliminary data of PI-PLC-β1 gene expression suggest that this and probably other biological markers could help us to know a priori who are the patients who have more chances to respond.
