Acute Coronary Syndrome Treatment Costs from the Perspective of the Supplementary Health System

AbstractBackground:Acute coronary syndrome (ACS) is defined as a “group of clinical symptoms compatible with acute myocardial ischemia”, representing the leading cause of death worldwide, with a high clinical and financial impact. In this sense, the development of economic studies assessing the costs related to the treatment of ACS should be considered.Objective:To evaluate costs and length of hospital stay between groups of patients treated for ACS undergoing angioplasty with or without stent implantation (stent+ / stent-), coronary artery bypass surgery (CABG) and treated only clinically (Clinical) from the perspective of the Brazilian Supplementary Health System (SHS).Methods:A retrospective analysis of medical claims of beneficiaries of health plans was performed considering hospitalization costs and length of hospital stay for management of patients undergoing different types of treatment for ACS, between Jan/2010 and Jun/2012.Results:The average costs per patient were R$ 18,261.77, R$ 30,611.07, R$ 37,454.94 and R$ 40,883.37 in the following groups: Clinical, stent-, stent+ and CABG, respectively. The average costs per day of hospitalization were R$ 1,987.03, R$ 4,024.72, R$ 6,033.40 and R$ 2,663.82, respectively. The average results for length of stay were 9.19 days, 7.61 days, 6.19 days and 15.20 days in these same groups. The differences were significant between all groups except Clinical and stent- and between stent + and CABG groups for cost analysis.Conclusion:Hospitalization costs of SCA are high in the Brazilian SHS, being significantly higher when interventional procedures are required.

Percepção química e visual de Anastrepha fraterculus (Diptera, Tephritidae) em laboratório

A mosca-das-frutas-sul-americana, Anastrepha fraterculus (Wiedemann, 1830), é uma das principais pragas da fruticultura no Brasil. Durante a alimentação, as larvas fazem galerias nos frutos, alterando o sabor e prejudicando a produção e comercialização dos mesmos. O presente trabalho teve como objetivo estudar fatores envolvidos na escolha do hospedeiro por A. fraterculus. Foram avaliadas as respostas eletroantenográficas de machos e fêmeas a extratos etanólicos de frutos verdes e maduros de pessegueiro - Prunus persica, cultivar Chimarrita (Rosaceae), pitangueira - Eugenia uniflora (Myrtaceae), guabirobeira - Campomanesia xanthocarpa (Myrtaceae) e araçazeiro - Psidium cattleianum (Myrtaceae). Foram também observadas as influências da cor (amarela, verde e vermelha) e da composição do substrato de oviposição (polpas de araçá, guabiroba, pitanga e pêssego) na fecundidade da espécie. As respostas eletroantenográficas de fêmeas foram significativamente distintas para os extratos de guabiroba verde e madura, araçá maduro e pitanga verde. Em antenas de machos, as maiores despolarizações médias foram registradas em resposta aos extratos de guabiroba verde e madura, araçá verde e maduro e pitanga verde. As respostas eletrofisiológicas geradas não diferiram estatisticamente entre os sexos, para todos os tratamentos. A cor do substrato não afetou a oviposição. As fêmeas ovipositaram mais nos substratos contendo polpa de pêssego e de guabiroba, quando comparados aos respectivos controles.

Collaboration strategies and technological innovation: a contractual perspective of the relationship between firms and techonological centers

In this paper, a theoretical framework for analyzing the selection of governance structures for implementing collaboration agreements between firms and Technological Centers is presented and empirically discussed. This framework includes Transaction Costs and Property Rights’ theoretical assumptions, though complemented with several proposals coming from the Transactional Value Theory. This last theory is used for adding some dynamism in the governance structure selection. As empirical evidence of this theoretical explanation, we analyse four real experiences of collaboration between firms and one Technological Center. These experiences are aimed to represent the typology of relationships which Technological Centers usually face. Among others, a key interesting result is obtained: R&D collaboration activities do not need to always be organized through hierarchical solutions. In those cases where future expected benefits and/or reputation issues could play an important role, the traditional more static theories could not fully explain the selected governance structure for managing the R&D relationship. As a consequence, these results justify further research about the adequacy of the theoretical framework presented in this paper in other contexts, for example, R&D collaborations between firms and/or between Universities or Public Research Centers and firms.

Empiricism in ecological economics: a perspective from complex systems theory

Economies are open complex adaptive systems far from thermodynamic equilibrium, and neo-classical environmental economics seems not to be the best way to describe the behaviour of such systems. Standard econometric analysis (i.e. time series) takes a deterministic and predictive approach, which encourages the search for predictive policy to ‘correct’ environmental problems. Rather, it seems that, because of the characteristics of economic systems, an ex-post analysis is more appropriate, which describes the emergence of such systems’ properties, and which sees policy as a social steering mechanism. With this background, some of the recent empirical work published in the field of ecological economics that follows the approach defended here is presented. Finally, the conclusion is reached that a predictive use of econometrics (i.e. time series analysis) in ecological economics should be limited to cases in which uncertainty decreases, which is not the normal situation when analysing the evolution of economic systems. However, that does not mean we should not use empirical analysis. On the contrary, this is to be encouraged, but from a structural and ex-post point of view.

An input-output analysis of the "key" sectors in CO2 emissions from a production perspective: an application to the spanish economy

Here we present an approach that allows the identification of the "key" productive sectors responsible for CO2 emission. For this purpose, we develop an input–output methodology from a supply perspective. We focus on the impact of an increase in the value-added of the different productive sectors on total CO2 emissions and we identify the productive sectors responsible for the increase in CO2 emissions when there is an increase in the income of the economy. The approach shows the contribution of the various sectors to CO2 emission from a production perspective and allows us to identify the sectors that deserve more consideration for mitigation policies. This analysis is complementary to the input–output analysis from a demand perspective. The methodology is applied to the Spanish economy.
