La fotochemioterapia extracorporea (ECP) nel trattamento delle glomerulonefriti

I pazienti con glomerulopatie con sindrome nefrosica hanno poche opzioni di trattamento efficace. Riportiamo la nostra esperienza sull'utilizzo della fotochemioterapia extracorporea ( ECP) in 9 pazienti in cui non era stata osservata una risposta efficace/duratura alla convenzionale terapia farmacologica. L’ECP è una promettente terapia immunomodulante, che è stata utilizzata con successo nel trattamento di altre condizioni immunomediate come il rigetto nel trapianto e il GvHD. METODI: In questo studio abbiamo arruolato 9 pazienti, 5 maschi e 4 femmine, età media 32.7±8.9 anni, affetti da sindrome nefrosica e non responsivi/resistenti alle comuni terapie. Il follow-up medio è stato di 41.3±21.7 mesi. Tutti i pazienti sono stati sottoposti a cicli di fotochemioterapia extracorporea secondo il seguente schema: 1ciclo (2 sedute in 2 giorni consecutivi) ogni 15 giorni per tre mesi, seguito da 1ciclo al mese per tre mesi. Il follow up è stato effetuatio ogni 3 mesi durante il primo anno e poi ogni 12 mesi. Durante il follow up sono stati monitorati pressione arteriosa, funzione renale, marcatori diretti ed indiretti di attività della malattia e indici di flogosi. RISULTATI: attraverso l'analisi dei parametri ematochimici indici di attività di malattia, e monitorando l'eventuale progressione della malattia renale, è stato possibile dimostrare che l' ECP può rappresentare per casi selezionati di pazienti una valida ulteriore opzione terapeutica. Secondo i risultati preliminari tale trattamento risulta inoltre caratterizzato da un eccellente profilo di sicurezza . CONCLUSIONI: I risultati osservati suggeriscono che l’ECP è un trattamento efficace per i pazienti con glomenulonefriti con sindrome nefrosica, soprattutto in coloro che presentano ancora una buona funzionalità renale. Valutazioni cliniche aggiuntive dovranno aiuteranno a definire meglio la popolazione di pazienti in cui ECP sia più efficace e raccomandabile.

Classic and overlap chronic graft-versus-host disease (cGVHD) is associated with superior outcome after extracorporeal photopheresis (ECP)

The National Institutes of Health (NIH) classification of graft-versus-host disease (GVHD) is a significant improvement over prior classifications, and has prognostic implications. We hypothesized that the NIH classification of GVHD would predict the survival of patients with GVHD treated with extracorporeal photopheresis (ECP). Sixty-four patients with steroid refractory/dependent GVHD treated with ECP were studied. The 3-year overall survival (OS) was 36% (95% confidence interval [CI] 13-59). Progressive GVHD was seen in 39% of patients with any acute GVHD (aGVHD) (classic acute, recurrent acute, overlap) compared to 3% of patients with classic chronic GVHD (cGVHD) (P=.002). OS was superior for patients with classic cGVHD (median survival, not reached) compared to overlap GVHD (median survival, 395 days, 95% CI 101 to not reached) and aGVHD (delayed, recurrent or persistent) (median survival, 72 days, 95% CI 39-152). In univariate analyses, significant predictors of survival after ECP included GVHD subtype, bilirubin, platelet count, and steroid dose. In multivariate analyses overlap plus classic cGVHD was an independent prognostic feature predictive of superior survival (hazard ratio [HR] 0.34, 95% CI 0.14-0.8, p=.014). This study suggests that NIH classification can predict outcome after ECP for steroid refractory/dependent GVHD.

An Assessment of US Progress towards its Pledge on Climate Change Mitigation. CEPS ECP Report No. 12, 15 October 2012

In 2009, President Obama pledged that, by 2020, the United States would achieve reductions in greenhouse gas emissions of 17% from 2005 levels. With the failure of Congress to adopt comprehensive climate legislation in 2010, the feasibility of the pledge was put in doubt. However, we find that the United States is near to reaching this goal: the country is currently on course to achieve reductions of 16.3% from 2005 levels in 2020. Three factors contribute to this outcome: greenhouse gas regulations under the Clean Air Act, secular trends including changes in relative fuel prices and energy efficiency and sub-national efforts. Perhaps even more surprising, domestic emissions are probably lower than would have been the case if the Waxman-Markey cap-and-trade proposal had become law in 2010. At this point, however, the United States is expected to fail to meet its financing commitments under the Copenhagen Accord for 2020.

Meningoencefalite necrotizante de cão Maltês

A Meningoencefalite Necrotizante (MEN) é uma encefalopatia causada por uma disfunção inflamatória de característica necrotizante. O objetivo deste relato é descrever os aspectos clínicos e anatomopatológicos da Meningoencefalite Necrotizante (MEN) em um cão Maltês. A doença tem um caráter necrótico único e está relacionada intimamente à Encefalite do Cão Pug (ECP) devido a suas semelhanças, bem como à Leucoencefalite Necrotizante (LEN). Embora o primeiro relato de caso de ECP tenha mais de 15 anos e o primeiro relato de caso de MEN em Maltês tenha 11 anos, há muito a ser revelado sobre a etiologia e os mecanismos imunopatológicos da doença. Neste trabalho, relata-se o caso de um cão Maltês com sinais que foram compatíveis com a MEN. Foram detectadas nas imagens macroscópicas, cavitação cerebral, e na microscopia, perda de células do parênquima em certas regiões do córtex cerebral. A partir dessas descobertas descreve-se o primeiro caso de MEN em cão Maltês no Brasil.

Effects of equine chorionic gonadotropin and type of ovulatory stimulus in a timed-AI protocol on reproductive responses in dairy cows

The objectives were to evaluate the effects of equine chorionic gonadotropin (eCG) supplementation (with or without eCG) and type of ovulatory stimulus (GnRH or ECP) on ovarian follicular dynamics, luteal function, and pregnancies per AI (P/AI) in Holstein cows receiving timed artificial insemination (TAI). On Day 0, 742 cows in a total of 782 breedings, received 2 mg of estradiol benzoate (EB) and one intravaginal progesterone (P4) insert (CIDR). On Day 8, the CIDR was removed, and all cows were given PGF2 alpha and assigned to one of four treatments in a 2 x 2 factorial arrangement: (1) CG: GnRH 48 h later; (2) CE: ECP; (3) EG: eCG + GnRH 48 It later; (4) EE: eCG + ECP. There were significant interactions for eCG x ovulatory stimulus and eCG x BCS. Cows in the CG group were less likely (28.9% vs. 33.8%; P < 0.05) to become pregnant compared with those in the EG group (odds ratio [OR] = 0.28). There were no differences in P/AI between CE and EE cows (30.9% vs. 29.1%; OR = 0.85; P = 0.56), respectively. Thinner cows not receiving eCG had lower P/AI than thinner cows receiving eCG (15.2% vs. 38.0%; OR = 0.20; P < 0.01). Treatment with eCG tended to increase serum progestesterone concentrations during the diestrus following synchronized ovulation (P < 0.10). However, the treatment used to induce ovulation did not affect CL volume or serum progesterone concentrations. In conclusion, both ECP and GnRH yielded comparable P/AI. However, eCG treatment at CIDR removal increased pregnancy rate in cows induced to ovulate with GnRH and in cows with lower BCS. (C) 2009 Elsevier Inc. All rights reserved.

The 434(G > C) polymorphism in the eosinophil cationic protein gene and its association with tissue eosinophilia in oral squamous cell carcinomas

Objective: The aim of this study was to investigate the prevalence of the Eosinophil cationic protein (ECP)-gene polymorphism 434(G > C) in oral squamous cell carcinoma (OSCC) patients and its association with tumor-associated tissue eosinophilia (TATE), demographic, clinical, and microscopic variables. Methods: The ECP genotypes of 165 healthy individuals and 157 OSCC patients were detected by PCR-RFLP analysis after cleavage of the amplified DNA sequence with enzyme PstI. TATE was obtained by morphometric analysis. Chi-square test or Fisher`s exact test was used to analyze the association of ECP-gene polymorphism 434(G > C) with TATE, demographic, clinical, and microscopic variables in OSCC patients. Disease-free survival and overall survival were calculated by the Kaplan-Meier product-limit actuarial method and the comparison of the survival curves were performed using log rank test. Results: Most of healthy individuals (53.33%) and OSCC patients (57.97%) were heterozygous for the ECP 434(G > C) polymorphism. Based on numerical differences, our results showed that OSCC patients with intense TATE and at least one C allele had a higher frequency of bilateral neck dissection, local recurrence, vascular embolization, involved resection margins, and postoperative radiotherapy. No statistically significant differences on survival rates were found in OSCC patients presenting different ECP 434(G > C) genotypes. Conclusions: These results suggest a tendency towards a poor clinical outcome in OSCC patients with intense TATE and 434GC/CC genotypes, probably due to an ECP genetic variant with altered cytotoxic activity.

VirtualECare: group decision supported by idea generation and argumentation

In the last years there has been a considerable increase in the number of people in need of intensive care, especially among the elderly, a phenomenon that is related to population ageing (Brown 2003). However, this is not exclusive of the elderly, as diseases as obesity, diabetes, and blood pressure have been increasing among young adults (Ford and Capewell 2007). As a new fact, it has to be dealt with by the healthcare sector, and particularly by the public one. Thus, the importance of finding new and cost effective ways for healthcare delivery are of particular importance, especially when the patients are not to be detached from their environments (WHO 2004). Following this line of thinking, a VirtualECare Multiagent System is presented in section 2, being our efforts centered on its Group Decision modules (Costa, Neves et al. 2007) (Camarinha-Matos and Afsarmanesh 2001).On the other hand, there has been a growing interest in combining the technological advances in the information society - computing, telecommunications and knowledge – in order to create new methodologies for problem solving, namely those that convey on Group Decision Support Systems (GDSS), based on agent perception. Indeed, the new economy, along with increased competition in today’s complex business environments, takes the companies to seek complementarities, in order to increase competitiveness and reduce risks. Under these scenarios, planning takes a major role in a company life cycle. However, effective planning depends on the generation and analysis of ideas (innovative or not) and, as a result, the idea generation and management processes are crucial. Our objective is to apply the GDSS referred to above to a new area. We believe that the use of GDSS in the healthcare arena will allow professionals to achieve better results in the analysis of one’s Electronically Clinical Profile (ECP). This attainment is vital, regarding the incoming to the market of new drugs and medical practices, which compete in the use of limited resources.

VirtualECare: group support in collaborative networks organizations for digital homecare

Collaborative Work plays an important role in today’s organizations, especially in areas where decisions must be made. However, any decision that involves a collective or group of decision makers is, by itself complex, but is becoming recurrent in recent years. In this work we present the VirtualECare project, an intelligent multi-agent system able to monitor, interact and serve its customers, which are, normally, in need of care services. In last year’s there has been a substantially increase on the number of people needed of intensive care, especially among the elderly, a phenomenon that is related to population ageing. However, this is becoming not exclusive of the elderly, as diseases like obesity, diabetes and blood pressure have been increasing among young adults. This is a new reality that needs to be dealt by the health sector, particularly by the public one. Given this scenarios, the importance of finding new and cost effective ways for health care delivery are of particular importance, especially when we believe they should not to be removed from their natural “habitat”. Following this line of thinking, the VirtualECare project will be presented, like similar ones that preceded it. Recently we have also assisted to a growing interest in combining the advances in information society - computing, telecommunications and presentation – in order to create Group Decision Support Systems (GDSS). Indeed, the new economy, along with increased competition in today’s complex business environments, takes the companies to seek complementarities in order to increase competitiveness and reduce risks. Under these scenarios, planning takes a major role in a company life. However, effective planning depends on the generation and analysis of ideas (innovative or not) and, as a result, the idea generation and management processes are crucial. Our objective is to apply the above presented GDSS to a new area. We believe that the use of GDSS in the healthcare arena will allow professionals to achieve better results in the analysis of one’s Electronically Clinical Profile (ECP). This achievement is vital, regarding the explosion of knowledge and skills, together with the need to use limited resources and get better results.

Group decision making for selection of an information system in a business context

The main objective of this work is to report on the development of a multi-criteria methodology to support the assessment and selection of an Information System (IS) framework in a business context. The objective is to select a technological partner that provides the engine to be the basis for the development of a customized application for shrinkage reduction on the supply chains management. Furthermore, the proposed methodology di ers from most of the ones previously proposed in the sense that 1) it provides the decision makers with a set of pre-defined criteria along with their description and suggestions on how to measure them and 2)it uses a continuous scale with two reference levels and thus no normalization of the valuations is required. The methodology here proposed is has been designed to be easy to understand and use, without a specific support of a decision making analyst.

Occurrence of Giardia cysts and Cryptosporidium oocysts in activated sludge samples in Campinas, SP, Brazil

Giardia and Cryptosporidium have caused several outbreaks of gastroenteritis in humans associated with drinking water. Contaminated sewage effluents are recognized as a potential source of waterborne protozoa. Due to the lack of studies about the occurrence of these parasites in sewage samples in Brazil, we compared the efficiency of two procedures for concentrating cysts and oocysts in activated sludge samples of one sewage treatment plant. For this, the samples were submitted to i) concentration by the ether clarification procedure (ECP) and to ii) purification by sucrose flotation method (SFM) and aliquots of the pellets were examined by immunofluorescence. Giardia cysts were present in all samples (100.0%; n = 8) when using ECP and kit 1 reagents, while kit 2 resulted in six positive samples (85.7%; n = 7). As for SFM, cysts were detected in 75.0% and 100.0% of these samples (for kit 1 and 2, respectively). Regarding Cryptosporidium, two samples (25.0%; kit 1 and 28.5% for kit 2) were detected positive by using ECP, while for SFM, only one sample (examined by kit 1) was positive (12.5%). The results of the control trial revealed Giardia and Cryptosporidium recovery efficiency rates for ECP of 54.5% and 9.6%, while SFM was 10.5% and 3.2%, respectively. Considering the high concentration detected, a previous evaluation of the activated sludge before its application in agriculture is recommended and with some improvement, ECP would be an appropriate simple technique for protozoa detection in sewage samples.

Estimativa dos custos das infeções nosocomiais da corrente sanguínea relacionadas com o cateter venoso central no Centro Hospitalar de Lisboa Ocidental

RESUMO - Introdução: As Infeções nosocomiais da corrente sanguínea associada a cateter venoso central (INCS-CVC) provocam um aumento das despesas hospitalares, traduzindo num aumento dos dias de internamento, consumo de antibióticos e de meios complementares de diagnóstico e terapêutica (MCDT). O presente estudo pretende avaliar os custos das INCS-CVC nos serviços de internamento do CHLO, no ano de 2012. Metodologia: Realizou-se um estudo retrospetivo de caso-controlo para determinar os custos adicionais inerentes às INCS-CVC. Foram identificados, em 2012, 32 doentes com infeção e 31 sem infeção. Os controlos foram extraídos da população tendo igual grupo diagnóstico Homogéneo (GDH), idade, sexo, serviço e duração de internamento e presença de CVC. As principais fontes de informação foram os registos da Comissão Controlo de Infeção (CCI) e do processo clinico eletrónico (PCE). A estimativa dos custos teve em consideração a duração de internamento, consumo de antibióticos e de MCDT. Resultados: A idade média dos casos e controlos foi de 66 e 69, respetivamente (p=0,432), 50% dos casos e 51,6% dos controlos eram do sexo masculino. Um total de 22 casos foi comparado com 22 controlos. A duração média de internamento dos casos e controlos foi de 70,8 e 36,6 dias, respetivamente (p=0,000). Em média o custo adicional por doente com antibióticos foi de 256€ (p=0,001). Nos casos o consumo de análises clinica foi 2,5 vezes superior e de exames imagiológicos 2 vezes superior aos controlos. O custo total médio adicional por doente foi de 20.737,6€. Conclusão: A ocorrência de INCS-CVC resultou num aumento significativo de utilização de recursos hospitalares e consequentemente num aumento dos custos hospitalares.

Still in the Era of Area Studies? Political-Scientific Perspectives on European Competition Policy in the 2000s

This note reviews the political-scientific literature on European competition policy (ECP) in the 2000s. Based on a data set extracted from four well-known journals, and using an upfront methodology and explicit criteria, it analyzes the literature both quantitatively and qualitatively. On the quantitative side, it shows that, although a few sub-policy areas are still neglected, ECP is not the under-researched policy it used to be. On the qualitative side, the literature has greatly improved since the 1990s: Almost all articles now present a clear research question, and most advance specific theoretical claims/hypotheses. Yet, improvements can be made on research design, statistical testing, and, above all, state-of-the-art theorizing (e.g. in the game-theoretical treatment of delegation problems). Indeed, it is paradoxical that ECP specialists do not pay more attention to theoretical questions which are so central to the actual policy area they study.
