Transformación de las instituciones colombianas que garanticen los derechos de los refugiados colombianos en el ecuador (2002-2013)

El objetivo de este trabajo de grado es realizar un análisis sobre las transformaciones institucionales colombianas que garanticen los derechos de refugiados colombianos en el Ecuador. Se analizará desde el enfoque neo institucionalista de la Ciencia Política, como la realidad de los refugiados colombianos en el Ecuador incide en las trasformaciones de las instituciones colombianas al constituirse en actores estratégicos en la configuración de las políticas y la institucionalidad del Estado colombiano. Al ser este un estudio de caso, se abordarán trayectorias vitales y migratorias de connacionales refugiados en Ecuador, víctimas del desplazamiento forzado, como también versiones de las instituciones del gobierno colombiano y opiniones, reflexiones y prácticas de fundaciones, ONG e instituciones internacionales especializadas, desde un enfoque cualitativo de investigación.

Valores de trabalho, satisfação global com o trabalho e satisfação com a vida : um estudo exploratório das diferenças sócio-demográficas em institutos de saúde

Foram objetivos do presente estudo proceder à análise das relações entre Valores de trabalho, Satisfação no trabalho e Satisfação com a vida em profissionais do sector da saúde e perceber se dimensões como antiguidade na empresa, os anos de experiência e o número de organizações, função, definição de objetivos, avaliação do desempenho, idade, escolaridade, sexo e estado civil tinham um papel nas dimensões principais do estudo. Foi recolhida uma amostra de 214 profissionais da saúde, sendo 24% do sexo masculino e com idades entre 21 e 71 anos (M=40.06; DP=10.93). Foram utilizados os instrumentos WVS (Schwartz, 1994), QSGT (Hackman & Oldham, 1975) e SWLS (Diener, 1984). Os resultados mostraram que existe uma relação positiva entre a satisfação na vida e a satisfação no trabalho; que quanto mais elevados eram os valores de trabalho Poder, Realização, Hedonismo, Estimulação, Auto direção, Benevolência, Conformismo e Segurança, maior era a Satisfação no trabalho; que quanto mais elevados são os valores de trabalho Poder, Realização, Hedonismo, Estimulação, Auto direção, Universalismo, Benevolência, Tradição, Conformismo e Segurança maior era a Satisfação com a vida; e que existem diferenças entre sexos, idade, estado civil e escolaridade ao nível dos valores de trabalho. Contudo, apesar da satisfação com a vida ser influenciada pela satisfação no trabalho e pelos valores de trabalho, estas dimensões, por si só, não explicam fortemente a satisfação com a vida.

New rôles and development rules for housing associations: rhe rise of design and build?

This paper summarises an initial report carried out by the Housing Business Research Group, of the University of Reading into Design and Build procurement and a number of research projects undertaken by the national federation of Housing Associations (NFHA), into their members' development programmes. The paper collates existing statistics from these sources and examines the way in which Design and Build procurement can be adapted for the provision of social housing. The paper comments on these changes and questions how risk averting the adopted strategies are in relation to long term housing business management issues arising from the quality of the product produced by the new system.

Effects of lipid-lowering drugs on reverse cholesterol transport gene expressions in peripheral blood mononuclear and HepG2 cells

Aims: The ATP-binding cassette transporters, ABCA1 and ABCG1, are LXR-target genes that play an important role in reverse cholesterol transport. We examined the effects of inhibitors of the cholesterol absorption (ezetimibe) and synthesis (statins) on expression of these transporters in HepG2 cells and peripheral blood mononuclear cells (PBMCs) of individuals with primary (and nonfamilial) hypercholesterolemia (HC). Materials & methods: A total of 48 HC individuals were treated with atorvastatin (10 mg/day/4 weeks) and 23 were treated with ezetimibe (10 mg/day/4 weeks), followed by simvastatin (10 mg/day/8 weeks) and simvastatin plus ezetimibe (10 mg of each/day/4 weeks). Gene expression was examined in statin- or ezetimibe-treated and control HepG2 cells as well as PBMCs using real-time PCR. Results: In PBMCs, statins and ezetimibe downregulated ABCA1 and ABCG1 mRNA expression but did not modulate NR1H2 (LxR-beta) and NR1H3 (LXR-alpha) levels. Positive correlations of ABCA1 with ABCG1 and of NR1H2 with NR1H3 expressions were found in all phases of the treatments. In HepG2 cells, ABCA1 mRNA levels remained unaltered while ABCG1 expression was increased by statin (1.0-10.0 mu M) or ezetimibe (5.0 mu M) treatments. Atorvastatin upregulated NR1H2 and NR1H3 only at 10.0 mu M, meanwhile ezetimibe (1.0-5.0 mu M) downregulated NR1H2 but did not change NR1H3 expression. Conclusion: Our findings reveal that lipid-lowering drugs downregulate ABCA1 and ABCG1 mRNA expression in PBMCs of HC individuals and exhibit differential effects on HepG2 cells. Moreover, they indicate that the ABCA1 and ABCG1 transcript levels were not correlated directly to LXR mRNA expression in both cell models treated with lipid-lowering drugs.

Densidade de plantas e produção de amendoim

Para estudar o efeito da densidade de plantas sobre a produção de vagens e seus componentes na cultura do amendoim cv. Tatu, em solos com diferentes fertilidades, foram realizados três experimentos, em condições de campo, no município de Pontal, SP, em um Latossolo Roxo, em anos agrícolas distintos, no cultivo das águas. As densidades estudadas foram 5, 8, 11, 14, 17, 20, 23 e 26 plantas por metro, em espaçamento de 0,60 m entre linhas. O componente de produção responsável pela variação da produção de vagens por planta foi o número de vagens, tendo diminuído com o aumento da densidade de plantas. Nas maiores densidades de plantas, as produções por planta foram menores, todavia devido à maior população de plantas, foram obtidas nestas as maiores produtividades de vagens. Produtividades de vagens, sem perdas significativas em relação às maiores densidades, foram obtidas nas densidades de 14 plantas por metro em solo de alta fertilidade e de 11 plantas por metro em solos de média/baixa fertilidades, que originaram, respectivamente, 12,92, 10,67 e 10,93 plantas por metro à colheita.

CARDIOVASCULAR EFFECTS OF CENTRAL CLONIDINE IN CONSCIOUS RATS AFTER HYPOTHALAMIC-LESIONS

The central injection of clonidine (an alpha-2-adrenoceptor agonist) in conscious normotensive rats produces hypertensive responses and bradycardia. The present study was performed to investigate the effect of electrolytic lesions in the anteroventral third ventricle (AV3V) region or in the lateral hypothalamus (LH) on the pressor and bradycardic responses induced by central clonidine in rats. Mean arterial pressure and heart rate were recorded in sham or AV3V-lesioned rats with cerebral stainless steel cannulae implanted into the lateral cerebral ventricle (ICV) or LH. and in sham or bilateral LH-lesioned rats with cannulae-implanted ICV. The injection of clonidine (40 nmol) ICV or into the LH of sham rats produced a pressor response (37 +/- 2-48 +/- 3 mmHg) and bradycardia (-45 +/- 10--93 +/- 6 bpm). After AV3V-lesion (3 and 12 days) or LH-lesion (3 days) the pressor response was abolished and a small hypotensive response was induced by the injection of clonidine (-1 +/- 3--16 +/- 3 mmHg). The bradycardia (-27 +/- 6--57 +/- 11 bpm) was reduced, but not abolished by the lesions. These results show that the AV3V region and LH are important cerebral structures that participate in the excitatory pathways involved in the pressor response to central clonidine in rats. They also suggest that, in the absence of these pressor pathways, the hypotensive responses to central clonidine may appear in conscious rats.

Gerenciamento dos resíduos de serviços de saúde do pronto socorro de um hospital escola na cidade de Botucatu

Health Care Waste (HCW) represents 1%, and it has presently gained a lot of importance. Adequate management is one of the great challenges to be faced by health care centers. It has gained distinction and been widely discussed by members of the sectors involved with sanitation, public health and environmental issues due to waste physical, chemical biological characteristics, which pose potential risk to the environment and public health. The present study aims at evaluating HCW internal management by following all its phases, determining indicators, classifying and quantifying, establishing production rates (kg /patient/day) for the sector and designing materials to disseminate appropriate HCW disposal in the Emergency Room of the UNESP University Hospital in the city of Botucatu according to the guidelines presently in force. : From June to October 2011, the waste flow was observed from its production to final disposal. Four weight measurements were performed on four consecutive days in the month of August by using a properly calibrated (in grams) digital scale at the times scheduled for collection of the produced waste. Hence, the daily and monthly amounts were estimated according to their classification. All the waste packaged in the bags in garbage cans in the Emergency Room for a 24-hour period was considered to be a sample. Separation was not adequately performed in that sector, and waste from Group A was mixed with that from Group D. The amount of infectious waste produced in the sector corresponded to 87.80 %, common waste to 10.93 % and recyclable waste to 1.27%. The mean daily HCW production was of 123.300 kg/day, and the total monthly production was of 3,822 kg/month, which was distributed as follows: Group A 3,355,750 kg/month; Group D 417,570 kg/month and recyclables 48,670 kg/month. The production rate corresponded to 0.47 kg/patient/day, thus showing... (Complete abstract click electronic access below)

Previous Percutaneous Coronary Intervention as Risk Factor for Coronary Artery Bypass Grafting

Background: Percutaneous coronary intervention (PCI) has increased as the initial revascularization strategy in chronic coronary artery disease. Consequently, more patients undergoing coronary artery bypass grafting (CABG) have history of coronary stent. Objective: Evaluate the impact of previous PCI on in-hospital mortality after CABG in patients with multivessel coronary artery disease. Methods: Between May/2007 and June/2009, 1099 consecutive patients underwent CABG on cardiopulmonary bypass. Patients with no PCI (n=938, 85.3%) were compared with patients with previous PCI (n=161, 14.6%). Logistic regression models and propensity score matching analysis were used to assess the risk-adjusted impact of previous PCI on in-hospital mortality. Results: Both groups were similar, except for the fact that patients with previous PCI were more likely to have unstable angina (16.1% x 9.9%, p=0.019). In-hospital mortality after CABG was higher in patients with previous PCI (9.3% x 5.1%, p=0.034) and it was comparable with EuroSCORE and 2000 Bernstein-Parsonnet risk score. Using multivariate logistic regression analysis, previous PCI emerged as an independent predictor of postoperative in-hospital mortality (odds ratio 1.94, 95% CI 1.02-3.68, p=0.044) as strong as diabetes (odds ratio 1.86, 95% CI 1.07-3.24, p=0.028). After computed propensity score matching based on preoperative risk factors, in-hospital mortality remained higher among patients with previous PCI (odds ratio 3.46, 95% CI 1.10-10.93, p=0.034). Conclusions: Previous PCI in patients with multivessel coronary artery disease is an independent risk factor for in-hospital mortality after CABG. This fact must be considered when PCI is indicated as initial alternative in patients with more severe coronary artery disease. (Arq Bras Cardiol 2012;99(1):586-595)

Intervenção Coronariana Percutânea prévia como fator de risco para Revascularização Miocárdica

FUNDAMENTO: A Intervenção Coronariana Percutânea (ICP) vem aumentando na doença arterial coronariana crônica. Consequentemente, cada vez mais pacientes submetidos a Cirurgia de Revascularização Miocárdica (CRM) apresentam stent coronariano. OBJETIVO: Avaliar a influência do antecedente de stent coronariano na mortalidade hospitalar após CRM. MÉTODOS: Análise prospectiva com 1.099 pacientes consecutivos submetidos a CRM com circulação extracorpórea, entre maio/2007 e junho/2009. Pacientes sem ICP prévia (n = 938; 85,3%) foram comparados com pacientes com ICP prévia (n = 161; 14,6%), utilizando modelos de regressão logística e análise de pareamento de amostras. RESULTADOS: Ambos os grupos apresentavam semelhança em relação aos fatores de risco, exceto pela maior presença de pacientes com angina instável no grupo com ICP prévia (16,1% vs. 9,9%; p = 0,019). A mortalidade hospitalar após CRM foi maior entre os pacientes com ICP prévia (9,3% vs. 5,1%, p = 0,034), e foi semelhante à esperada em relação ao EuroSCORE e ao 2000 Bernstein-Parsonnet score. Na análise com regressão logística multivariada a ICP prévia emergiu como fator de risco independente para mortalidade hospitalar pós-operatória (odds ratio 1,94; IC 95% 1,02-3,68; p = 0,044) tão forte quanto diabetes (odds ratio 1,86; IC 95% 1,07-3,24; p = 0,028). Após o pareamento dos grupos, a mortalidade hospitalar continuou sendo maior entre os pacientes com ICP prévia, com odds ratio 3,46 ; IC 95% 1,10-10,93; p = 0,034. CONCLUSÃO: A ICP prévia em pacientes com doença coronariana multiarterial é fator de risco independente para mortalidade hospitalar após CRM. Tal fato deve ser considerado quando a ICP for indicada como alternativa inicial em pacientes com doença arterial coronariana mais avançada. (Arq Bras Cardiol. 2012; [online].ahead print, PP.0-0)

Reliability of buildings in service limit state for maximum horizontal displacements

Brazilian design code ABNT NBR6118:2003 - Design of Concrete Structures - Procedures - [1] proposes the use of simplified models for the consideration of non-linear material behavior in the evaluation of horizontal displacements in buildings. These models penalize stiffness of columns and beams, representing the effects of concrete cracking and avoiding costly physical non-linear analyses. The objectives of the present paper are to investigate the accuracy and uncertainty of these simplified models, as well as to evaluate the reliabilities of structures designed following ABNT NBR6118:2003[1&] in the service limit state for horizontal displacements. Model error statistics are obtained from 42 representative plane frames. The reliabilities of three typical (4, 8 and 12 floor) buildings are evaluated, using the simplified models and a rigorous, physical and geometrical non-linear analysis. Results show that the 70/70 (column/beam stiffness reduction) model is more accurate and less conservative than the 80/40 model. Results also show that ABNT NBR6118:2003 [1] design criteria for horizontal displacement limit states (masonry damage according to ACI 435.3R-68(1984) [10]) are conservative, and result in reliability indexes which are larger than those recommended in EUROCODE [2] for irreversible service limit states.

Tissue properties of the human vertebral body sub-structures evaluated by means of microindentation

Purpose The better understanding of vertebral mechanical properties can help to improve the diagnosis of vertebral fractures. As the bone mechanical competence depends not only from bone mineral density (BMD) but also from bone quality, the goal of the present study was to investigate the anisotropic indentation moduli of the different sub-structures of the healthy human vertebral body and spondylophytes by means of microindentation. Methods Six human vertebral bodies and five osteophytes (spondylophytes) were collected and prepared for microindentation test. In particular, indentations were performed on bone structural units of the cortical shell (along axial, circumferential and radial directions), of the endplates (along the anterio-posterior and lateral directions), of the trabecular bone (along the axial and transverse directions) and of the spondylophytes (along the axial direction). A total of 3164 indentations down to a maximum depth of 2.5 µm were performed and the indentation modulus was computed for each measurement. Results The cortical shell showed an orthotropic behavior (indentation modulus, Ei, higher if measured along the axial direction, 14.6±2.8 GPa, compared to the circumferential one, 12.3±3.5 GPa, and radial one, 8.3±3.1 GPa). Moreover, the cortical endplates (similar Ei along the antero-posterior, 13.0±2.9 GPa, and along the lateral, 12.0±3.0 GPa, directions) and the trabecular bone (Ei= 13.7±3.4 GPa along the axial direction versus Ei=10.9±3.7 GPa along the transverse one) showed transversal isotropy behavior. Furthermore, the spondylophytes showed the lower mechanical properties measured along the axial direction (Ei=10.5±3.3 GPa). Conclusions The original results presented in this study improve our understanding of vertebral biomechanics and can be helpful to define the material properties of the vertebral substructures in computational models such as FE analysis.

Family diversity in social exclusion situations. Results and reflections on research, teaching and knowledge transfer activities

The purpose of this paper is to characterize the configurations of the families that live in contexts of social exclusion; provide conceptualizations of their operation mode; highlight the formative effects that neighborhood interdisciplinary practices with such families produce in the just graduated psychologists, included on the Extension Program. We wish to contribute to produce systematic knowledge that can account for such family configurations as potential receiver of integration policies. We are also interested on transferring the approach to diversity in the training of young professionals, in order not to be regarded as a deviation from ideal models, but as an expression of different strategies built by members of a community, to resolve children breeding and to bear their existences. This work is the result about reflections on productions inside a research fellowship: The complexities that takes the breeding in families who lives in a social exclusion situation; researches about breeding, carried out from signature Developmental Psychology II, and from de interdisciplinary work with psychologically assisted families in twelve suburbs of the city of La Plata (University Extension Program "Free Legal Offices" (Convention between Law and Social Sciences and Psychology Faculties, U.N.L.P.). From a qualitative methodology and an interdisciplinary participation, the results have arrive at the characterization and proposed conceptualizations of the included families and at the same time determine the benefits that brings with the work that articulates research and extension activities for the training of advanced students and young graduates.
