Neuro-Behçet: a clinical exercise

Behçet disease is a recurrent systemic vasculitis of unknown etiology, that involves vessels of nearly all sizes and types. Because of this, disease manifestations can occur at many sites throughout the body. Central nervous system (CNS) involvement may be parenchymal or nonparenchymal and has a global prevalence that ranges from 3% to 10%. Main signs of CNS involvement are pyramidal and those resulting from brain stem lesions. Aseptic meningitis, mental changes, sphincter disturbances, pseudobulbar syndrome, and deep sensory abnormalities may be seen. Analysis of cerebrospinal fluid, computed tomography (CT), magnetic resonance imaging (MRI), single-photon emission computed tomography (SPECT) and brain angiography offer assistance in the diagnosis. The course of disease can be primary progressive, secondary progressive or have a relapsing-remitting profile. Boluses of methylprednisolone for three days followed by cyclophosphamide are the treatment of choice. This papers discusses these aspects of neuro-Behcet on the basis of complex clinical cas

Benefícios dos Ativadores Seletivos dos Recetores de Vitamina D em Doentes Transplantados Renais

Severe chronic kidney disease may lead to disturbances, such as hyperphosphatemia, increased secretion of fibroblast growth factor -23 (FGF -23) and vitamin D deficiency. These may increase plasmatic levels of parathyroid hormone, and decrease plasmatic levels of calcium. Altogether, these may contribute to the development of secondary hyperparathyroidism, and to abnormalities in mineral metabolism. Kidney transplantation is the best option to improve longevity and quality of life in end -stage chronic kidney disease patients. Vitamin D deficiency has been associated with cardiovascular disease, which is the leading cause of death in chronic kidney disease. Therefore, diagnosing this deficiency may be pivotal for minimizing mortality in chronic kidney disease, because pharmacological treatments for this deficiency may be prescribed. Calcitriol is indicated for the treatment of vitamin D deficiency, both in chronic kidney disease and in kidney transplanted patients. However, calcitriol may increase the plasmatic levels of calcium and phosphorous, which can lead to vascular calcifications, that have been associated with cardiovascular mortality. Selective vitamin D receptor activators are indicated for the treatment of vitamin D deficiency in chronic kidney disease. These have the advantage of being associated with lower increases of plasmatic levels of calcium and phosphorous. These drugs also seem to have additional effects that may minimise patient morbidity and mortality, especially due to potentially reducing cardiovascular events. Unfortunately, there are few studies about the use of these drugs in kidney transplanted patients. Here we present a review about the physiology of vitamin D, the consequences of its deficiency in chronic kidney disease and in kidney transplanted patients, and about the diagnosis and treatment of this deficiency. Finally, we discuss the new line of research about the efficacy and safety of selective vitamin D receptor activators in kidney transplanted patients

Análise de uso de padrões de metadados em projetos de pesquisa e desenvolvimento na Embrapa Informática Agropecuária.

A Empresa Brasileira de Pesquisa Agropecuária (Embrapa) produz uma grande quantidade de dados como resultado das pesquisa que realiza. Os dados gerados abrangem diferentes domínios: solos, clima, coleções, dados de animais, dados bibliográficos, entre outros. Muitas vezes os projetos trocam ou reúsam a informação produzidas. Apesar disso, muitos deles ainda são armazenados de diferentes formas e usando diferentes formatos, como planilhas, sistemas de banco de dados, papel, entre outros. A necessidade ou possibilidade de integração/compartilhamento de informação entre esses sistemas ou mesmo com outras instituições de pesquisa, desencadeou ações para a incorporação de novas estruturas e conceitos aos sistemas desenvolvidos, no sentido de facilitar a interoperabilidade de dados. Uma abordagem para esse problema é a adoção de padrões de metadados bem estabelecidos para descrição desses dados. Nesse sentindo, a Embrapa Informática Agropecuária estabeleceu um grupo de trabalho cuja missão era identificar a situação de seus projetos de pesquisa quanto à adoção desses padrões. O grupo elaborou um conjunto de perguntas que foram apresentadas à maioria desses projetos, permitindo não apenas identificar a utilização de metadados, mas também descrever as principais observações e recomendações sobre esse tema. Este documento apresenta o trabalho realizado por esse grupo, bem como os resultados obtidos.bitstream/item/57307/1/Livro-BolPesq27-1.pd

Circular economy business models as context-forging opportunities: the role of circular managers in driving sustainable innovation in emerging markets

This research investigates how circular business managers develop, innovate, and implement circular economy business models (CEBMs). We apply the COM-B model as an analytical lens to identify key factors that drive CEBM development, innovation and implementation in an attempt to offer context-forging opportunities to facilitate more sustainable consumption behaviours. Based on semi-structured interviews with circular business managers in Brazil as emerging economy context, nonparticipant observations, and documentary analysis of secondary data, we explore CE managers’ motivation, capabilities and the opportunities presented to them, and how these drive CE ambitions. Findings underscore the both crucial and emerging role of circular managers and their influence on CEBMs as context-forging opportunities that can operate as pivotal agents in both enabling and encouraging consumers to enact sustainable behaviours. We conclude that CEBMs are essential for advancing cleaner production and consumption, as they introduce new approaches to doing business, producing, and consuming

Rail Infrastructure Pricing For Intercity Passenger Services In Europe: Possible Impacts On The Railways Competitive Framework

At the beginning of the 90’s, the European Union initiated a railways reform with the aim to face the decline of railway transport, as well as to increase railway competitiveness and interoperability at European scale. The First Railway Package of this reform focused on the split between infrastructure management and operation and, therefore, on the establishment of pricing systems. Due to lack of straight definition, the application of the Directives on infrastructure charges in the different European countries has given rise to a large spectrum of charging systems. It is a direct consequence of the differences in the charging philosophies (MC –marginal cost, MC+ - marginal cost with mark-ups, FC –Full Cost recovery, etc.), the charging types (single tariff, two-parts tariff) and the parameters (or variables) chosen for defining the amount of the charge in each particular case. This paper analyses the rail infrastructure charges in 23 European countries from the point of view of the parameters used for defining them. The analysis deepens the knowledge of qualitative differences between these countries’ pricing structure. Furthermore, it analyses its consequences in the total amount of the charge to be paid by passenger services running through links considered to be the best national railways relations in each one of the countries studied. Concerning the qualitative analysis, forty-six different types of variables were identified for the whole of the systems analysed. With regard to the quantitative field,calculations reveal that infrastructure charges range from 14,6 €/train-km to 0,6 €/train-km for “comparable” national links. The last part of this paper discusses the weight of those fares for the use of infrastructure for intercity rail passenger services with regard to its competitor mode. Results from an analysis of 100 national and international links allow drawing some conclusions on the possible impacts of railway infrastructure pricing on the railways competitive framework in Europe.Institute of Transport and Logistics Studies.

Early Rehospitalization Post-Kidney Transplant Due to Infectious Complications: Can We Predict the Patients at Risk?

INTRODUCTION: Rehospitalization early post-kidney transplant is common and has a negative impact in morbidity, graft survival, and health costs. Infection is one the most common causes, and identifying the risk factors for early readmission due to infectious complications may guide a preventive program and improve outcome. The aim of this study was to evaluate the incidence, characterize the population, and identify the risk factors associated with early readmission for infectious complications post-kidney transplantation. METHODS: We performed a retrospective cohort study of all the kidney transplants performed during 2015. The primary outcome was readmission in the first 3 months post-transplant due to infectious causes defined by clinical and laboratory parameters. RESULTS: We evaluated 141 kidney transplants; 71% of subjects were men, with an overall mean age of 50.8 ± 15.4 years. Prior to transplant, 98% of the patients were dialysis dependent and 2% underwent pre-emptive living donor kidney transplant. The global readmission rate was 49%, of which 65% were for infectious complications. The most frequent infection was urinary tract infection (n = 28, 62%) and the most common agent detected by blood and urine cultures was Klebsiella pneumonia (n = 18, 40%). The risk factors significantly associated with readmission were higher body mass index (P = .03), diabetes mellitus (P = .02), older donor (P = .007), and longer cold ischemia time (P = .04). There were 3 graft losses, but none due to infectious complications. CONCLUSION: There was a high incidence of early rehospitalization due to infectious complications, especially urinary tract infections to nosocomial agents. The risk factors identified were similar to other series.info:eu-repo/semantics/publishedVersio
