Abstract:
Enteropathogenic Escherichia coli (EPEC) infections are a leading cause of infantile diarrhea in developing nations. Multilocus sequence typing (MLST) characterizes bacterial strains based on the sequences of internal fragments in housekeeping genes. Little is known about strains of EPEC analyzed by MLST from Brazil. In this study, a diverse collection of 29 EPEC strains isolated from patients with diarrhea, admitted to the University Hospital of Ribeirao Preto, was characterized by MLST. Strain analysis demonstrated 22 different sequence types (STs), of which almost half (48%) were new, indicating a high genotype diversity. The 22 STs were divided by eBURST into 12 clonal complexes. It was not possible to correlate typical and atypical EPEC with other strains in the MLST database. This is the first study that analyzed EPEC strains from South America that are included in the E. coli MLST database. Nine (31%) out of 29 strains are part of the CC10 clonal complex, the major clonal complex in the database, which comprises 174 strains and 86 different STs, suggesting that these strains might be the most important intestinal pathogenic E. coli worldwide. Genetic relationships between typical and atypical EPEC, enterohemorrhagic E. coli, and enteroaggregative E. coli strains were not established by MLST.

Abstract:
ABSTRACT Enterohemorrhagic and enteropathogenic Escherichia coli (EHEC and EPEC, respectively) strains are closely related human pathogens that are responsible for food-borne epidemics in many countries. Integration host factor (IHF) and the locus of enterocyte effacement-encoded regulator (Ler) are needed for the expression of virulence genes in EHEC and EPEC, including the elicitation of actin rearrangements for attaching and effacing lesions. We applied a proteomic approach, using two-dimensional polyacrylamide gel electrophoresis in combination with matrix-assisted laser desorption ionization-time of flight mass spectrometry and a protein database search, to analyze the extracellular protein profiles of EHEC EDL933, EPEC E2348/69, and their ihf and ler mutants. Fifty-nine major protein spots from the extracellular proteomes were identified, including six proteins of unknown function. Twenty-six of them were conserved between EHEC EDL933 and EPEC E2348/69, while some of them were strain-specific proteins. Four common extracellular proteins (EspA, EspB, EspD, and Tir) were regulated by both IHF and Ler in EHEC EDL933 and EPEC E2348/69. TagA in EHEC EDL933 and EspC and EspF in EPEC E2348/69 were present in the wild-type strains but absent from their respective ler and ihf mutants, while FliC was overexpressed in the ihf mutant of EPEC E2348/69. Two dominant forms of EspB were found in EHEC EDL933 and EPEC E2348/69, but the significance of this is unknown. These results show that proteomics is a powerful platform technology for accelerating the understanding of EPEC and EHEC pathogenesis and identifying markers for laboratory diagnoses of these pathogens.

Abstract:
INTRODUCTION:Popliteal artery aneurysm (PAA) is the most common peripheral arterial aneurysm and the second most common aneurysm after abdominal aortic aneurysm (AAA). It presents a risk of occlusion, which may lead to acute ischemia and leg amputation. To prevent these risks, asymptomatic PAA >2cm and symptomatic PAA must be treated. Although open PPA repair (OPAR) is still the gold standard, endovascular PAA repair (EPAR) is increasingly used to manage PAA. The objective of this study is to compare the cost of these two medical procedures from the hospital perspective.METHODS:Data were retrieved from the administrative database of Lausanne University Hospital (CHUV – Switzerland). Based on diagnostic codes and medical procedure codes, we selected all patients who underwent OPAR or EPAR between 2011 and 2015. Patient's age, length of stay and cost were compared between both groups using Student t-test.RESULTS:We included seventy-three patient stays (OPAR forty and EPAR thirty-three). Gender balance was identical between groups (97 percent of male), but age was statistically significantly different (OPAR 67.5, EPAR 73, p = .04). EPAR induced shorter mean length of stay (5.1 days versus 11.7 days, p = .0000) and lower mean global cost (CHF 16,555 versus CHF23,514, p = .0085). Cost of procedure amounted to CHF 9,536 for OPAR versus CHF 3,848 for EPAR, medical supply and implants amounted to CHF 1,284 for OPAR versus CHF 7,041 for EPAR and other costs of hospital stay amounted to CHF 12,694 for OPAR versus CHF 5,666 for EPAR. (CHF 1.00 = USD1.00 = EURO 0.93)CONCLUSIONS:With higher patency rate, OPAR is still associated with better medical outcomes than EPAR. But EPAR is significantly less costly than OPAR. Implant cost of EPAR is more than offset by longer length of stay and operating time of OPAR.

Abstract:
ABSTRACTObjectiveParoxysmal supraventricular tachycardia (SVT) is a common dysrhythmia treated in the prehospital setting. Emergency medical service (EMS) agencies typically require patients treated for SVT to be transported to the hospital. This retrospective cohort study evaluated the impact, paramedic adherence, and patient re-presentation rates of a treat-and-release (T+R) protocol for uncomplicated SVT.MethodsData were linked from the Alberta Health Services EMS electronic patient care record (EPCR) database for the City of Calgary to the Regional Emergency Department Information System (REDIS). All SVT patients treated by EMS between September 1, 2010, and September 30, 2012, were identified. Databases were queried to identify re-presentations to EMS or an emergency department (ED) within 72 hours of T+R.ResultsThere were 229 confirmed SVT patient encounters, including 75 T+R events. Of these 75 T+R events, 10 (13%, 95% confidence interval [CI] [7.4, 23]) led to an EMS re-presentation within 72 hours, and 4 (5%, 95% CI [2.1, 13]) led to an ED. All re-presentations were attributed to a single individual. After excluding 15 records that were incomplete due to limitations in the EPCR platform, 43 of 60 (72%) T+R encounters met all protocol criteria for T+R.ConclusionThe T+R protocol evaluated in this study applied to a significant proportion of patients presenting to EMS with SVT. Risk of re-presentation following T+R was low, and paramedic protocol adherence was reasonable. T+R appears to be a viable option for uncomplicated SVT in the prehospital setting.

Abstract:
IntroductionThe geographical distribution of hypoglycemic events requiring emergency assistance was explored in Andalusia (Spain), and potentially associated societal factors were determined.Research design and methodsThis was a database analysis of hypoglycemia requiring prehospital emergency assistance from the Public Company for Health Emergencies (Empresa Pública de Emergencias Sanitarias (EPES)) in Andalusia during 2012, which served 8 393 159 people. Databases of the National Statistics Institute, Basic Spatial Data of Andalusia and System of Multiterritorial Information of Andalusia were used to retrieve spatial data and population characteristics. Geographic Information System software (QGIS and GeoDA) was used for analysis and linkage across databases. Spatial analyses of geographical location influence in hypoglycemic events were assessed using Moran’s I statistics, and linear regressions were used to determine their association with population characteristics.ResultsThe EPES attended 1 137 738 calls requesting medical assistance, with a mean hypoglycemia incidence of 95.0±61.6 cases per 100 000 inhabitants. There were significant differences in hypoglycemia incidence between basic healthcare zones attributable to their geographical location in the overall population (Moran’s I index 0.122, z-score 7.870, p=0.001), women (Moran’s I index 0.088, z-score 6.285, p=0.001), men (Moran’s I index 0.076, z-score 4.914, p=0.001) and aged >64 years (Moran’s I index 0.147, z-score 9.753, p=0.001). Hypoglycemia incidence was higher within unemployed individuals (β=0.003, p=0.001) and unemployed women (β=0.005, p=0.001), while lower within individuals aged <16 years (β=−0.004, p=0.040), higher academic level (secondary studies) (β=−0.003, p=0.004) and women with secondary studies (β=−0.005, p<0.001). In subjects aged >64 years, lower rate of hypoglycemia was associated with more single-person homes (β=−0.008, p=0.022) and sports facilities (β=−0.342, p=0.012).ConclusionsThis analysis supports the geographical distribution of hypoglycemia in the overall population, both genders and subjects aged >64 years, which was affected by societal factors such as unemployment, literacy/education, housing and sports facilities. These data can be useful to design specific prevention programs.

Abstract:
When solving instances of problem domains that feature a large branching factor, A* may generate a large number of nodes whose cost is greater than the cost of the optimal solution. We designate such nodes as surplus. Generating surplus nodes and adding them to the OPEN list may dominate both time and memory of the search. A recently introduced variant of A* called Partial Expansion A* (PEA*) deals with the memory aspect of this problem. When expanding a node n, PEA* generates all of its children and puts into OPEN only the children with f = f (n). n is re-inserted in the OPEN list with the f -cost of the best discarded child. This guarantees that surplus nodes are not inserted into OPEN. In this paper, we present a novel variant of A* called Enhanced Partial Expansion A* (EPEA*) that advances the idea of PEA* to address the time aspect. Given a priori domain- and heuristic- specific knowledge, EPEA* generates only the nodes with f = f(n). Although EPEA* is not always applicable or practical, we study several variants of EPEA*, which make it applicable to a large number of domains and heuristics. In particular, the ideas of EPEA* are applicable to IDA* and to the domains where pattern databases are traditionally used. Experimental studies show significant improvements in run-time and memory performance for several standard benchmark applications. We provide several theoretical studies to facilitate an understanding of the new algorithm.

Abstract:
Shiga toxin-encoding genes (stx) of enterohemorrhagic Escherichia coli (EHEC) can be lost during infection or in vitro cultivation, and in clinical practice, it is difficult to distinguish EHEC that have lost stx (EHEC-LST) from enteropathogenic E. coli (EPEC), as both are stx-negative and eae-positive. In this study, we performed whole-genome sequencing (WGS) of a stx-negative, eae-positive E. coli O63:H6 isolate from a child with hemolytic uremic syndrome and compared its genome with those of nine E. coli O63:H6 strains in public databases. Virulence gene profiles were analyzed and core-genome multilocus sequence typing (cgMLST) was conducted. The virulence gene profile of our isolate was consistent with EHEC, except for the absence of stx, and the isolate clustered with seven EHEC strains but was distant from two EPEC strains in cgMLST. In genome alignment, our isolate exhibited a high nucleotide identity with EHEC strain 377323_2f but displayed a gap corresponding to the stx-harboring prophage sequence. Overall, our isolate was genetically closely related to EHEC strains, consistent with this being an EHEC-LST strain. As EHEC-LST may be misdiagnosed as EPEC in routine laboratories, comparative genomic analysis using WGS can be useful to determine whether stx-negative and eae-positive isolates are EHEC-LST or EPEC.

RESUMO - Objetivos: Caracterizar a adesão à terapêutica nos doentes do CHLN, na área do VIH/SIDA, Esclerose, Artrite Reumatóide, Psoríase e Paramiloidose e avaliar a hipótese de ser possível prever o risco de um doente se tornar, num doente sem adesão. Metodologia: Estudo retrospetivo, observacional e longitudinal, realizado entre Janeiro de 2010 a 31 de Dezembro de 2013, a 4.761 doentes, em que a adesão à terapêutica foi calculada com base nos registos informáticos das dispensas de medicação, efectuados pelos Serviços Farmacêuticos, com recurso à Compliance Rate (CR) e utilizada como variável dependente. A estatística descritiva foi utilizada para caracterizar os doentes e os seus levantamentos e a regressão logística para avaliar o efeito das variáveis (idade, sexo, distrito de residência, período de observação, número de interrupções superiores a trinta dias e tempo até à primeira interrupção) sobre a adesão à terapêutica. Resultados e Conclusões: A percentagem de doentes com adesão foi de 64%, no entanto no HIV/Sida e na Artrite Reumatóide e Psoríase esta percentagem foi significativamente mais baixa, 42% dos doentes interromperam a terapêutica por períodos superiores a 30 dias, ocorrendo essa interrupção maioritariamente entre o primeiro e segundo ano de terapêutica. O modelo de regressão logística permitiu verificar que só com as variáveis sociodemográficas não é possível prever o risco de um doente se tornar num doente sem adesão, sendo para tal necessário adicionar ao modelo a variável número de interrupções superiores a 30 dias que foi identificada como importante factor preditivo da não adesão (OR=15,9, p=0,000).
ABSTRACT - Objectives: To characterize adherence to therapy in patients of CHLN on HIV / AIDS, Sclerosis, Rheumatoid Arthritis, Psoriasis and Amyloidosis and evaluate the hypothesis to be possible predict the risk of a patient becoming, non adherent patient. Methods: Retrospective, observational, longitudinal study conducted from January 2010 to December 2013, through 4.761 patients, in which adherence was calculated based on computer records of refill medication, by Pharmaceutical Services, through the Compliance Rate (CR) and used for the dependent variable. Descriptive statistics were used to characterize patients and their surveys and logistic regression to assess the effect of the variables (age, sex, district of residence, period of observation, number of interruptions exceeding thirty days and time to first break) on adherence. Results and Conclusions: The percentage of patients with refill adherence was 64%, however in the HIV / AIDS and Rheumatoid Arthritis and Psoriasis significantly this percentage was lower, 42% of patients interrupt therapy for longer than 30 days, occurring mostly this interruption between the first and second year of treatment. The logistic regression model has shown that with sociodemographic variables is not possible to predict the risk of a patient becoming a non-adherent patient and it is therefore necessary to add to the model the number of interruptions longer than 30 days variable. This variable was identified as an important predictor of non-adherence (OR = 15.9, p=0.000).

Information management is essential for health professionals in order to maintain a level of productivity for health care services management. This is significant when treating cancer patients. The main target of this study was to employ computers to enhance the daily practice of Oncology Unit (Sotiria Hospital, Athens, Greece). Accordingly, a computerized system was developed consisting of three modules: the EPR, the Image Archive, and the Lab Module. The EPR Module is a database application that stores clinical results, physician orders, and several administrative data. The Image Archive Module is used mainly for the reduction of images volume and the Lab Module stores information about the patient blood samples. These two modules interoperate through EPR Module under strict data security policies. Key physicians, biologists, and secretary personnel are involved in data entry and information management, while the system administrator is responsible for the system functioning. Improved health care, user satisfaction, and cost savings were the most important benefits gained with this system. The need of similar systems in oncology is crucial and could involve additional applications, such as quality of life (QoL) systems.

Abstract:
Due to the increased size and complexity of large-scale commercial and industrial structures, it is increasingly challenging to manage key engineering data including analysis and design results of these structures. This paper presents a novel approach of using large-scale database systems as a means to gather, organize and manage key analysis and design results of a large-scale structure. Specifically, this paper describes in detail the development process of the backend database management system (DBMS) for the U.S. EPR™ Standard Nuclear Power Plant (NPP) Nuclear Island (NI) structures. The database system consists of three parent database tables to represent three representative groups of load combinations applicable to the U.S. EPR™ Standard NPP. Inheriting all characteristics of an applicable parent table, a primary child table in the database system represents a particular U.S. EPR™ NI Safety-Related structure in its entirety while a secondary child table a group of slabs or walls of the structure. Each secondary table is comprised of database fields that are representative of various structural demands, section capacities, reinforcing ratios, and demand-to-capacity ratios for three reinforced concrete design conditions (i.e., combined axial force and bending design, in-plane shear design, and out-of-plane shear design). The complete database system with fully populated tables is a central repository where all analysis and design results for the U.S. EPR™ NI Common Basemat structures are stored and sorted. To facilitate data queries from the developed backend database system, this paper introduces a user-friendly frontend interface program developed using Visual Basic Application (VBA) with Excel. Potential benefits of the developed database system are demonstrated with simple application examples involving simple data queries only followed by complex engineering tasks that require a more advanced form of data queries.

Abstract:
Abstract The European Pressurized Water Reactor Project (EPR) is based on an innovative design concept for a new type of pressurized water reactor. The development of this concept will be carried out by a consortium of international partners and customers based in Germany and France. During the development of the EPR large amounts of up-to-date engineering data (i.e. CAD data, planning documentation) have to be made available to all project partners for presentation and development. This paper describes the web-based tool Virtual Web Plant (VWP), a tool to integrate 3D models from various CAD plant design tools and to display them interactively. The tool receives the data through the Internet. We describe the special advantages of an object-oriented database for the storage of the graphical data are shown. Through the application of object-oriented databases, it is possible to define various views of the logical plant structure, for example. The user is hereby able to navigate easily through both the plant structure and the project documentation. The work presented in this paper is part of a Virtual Reality Research Project of the Heinz Nixdorf Institute and the Siemens AG KWU.

In the present detailed engineering phase of the plant under construction in Finland (Okiluoto 3) and in France (Flamanville 3), some actions were conducted in order to improve the knowledge of the hydraulic behavior of the innovative Reactor Pressure Vessel internals (RPV). The RPV internals are mainly derived from former French N4 or German Konvoi with some evolutions to take into account the operating experience. Design and validation of the internals were performed within AREVA’s engineering teams, which develop state of the art methods in the field of thermohydraulic testing. The experimental validation program was closely followed by EDF. Moreover, an EDF R&D project, whose results are not addressed here, was held to consolidate the RPV internals conception. The aim of the paper is to present the hydraulic tests performed on mock-ups to characterize the hydraulic behavior of the innovative EPR Reactor Pressure Vessel internals, and to introduce the role of these tests in the global conception process of the EPR RPV internals (CFD code qualification, design validation, database...). The qualification of the CFD computer codes will be described in a forthcoming paper. Three different mock-ups are presented to illustrate these tests: • JULIETTE for the reactor pressure vessel lower internals, • ROMEO for the reactor pressure vessel upper internals, • MAGALY for the design of the skeleton-type control rod guide assembly.

Abstract:
The development of the MCCI code COSACO specifically addresses the ex-vessel MCCI phase of the core melt retention concept of the EPR. The general philosophy behind COSACO is a rigerous representation of thermochemical phenomena related to the MCCI. In particular, the code incorporates a real solution database to predict the simultaneous formation of solid and liquid phases as well as chemical reactions for a significant number melt constituents. This offers a great flexibility in terms of application to MCCIs involving reactor materials and to tests conducted with simulant melts. The approach to model heat transfer in oxidic melt pools is based on the phase segregation hypothesis. Besides a brief description of the principal models incorporated in COSACO, this paper highlights specific thermochemical effects that arose as part of post-test calculations of the tests MACE M3b and MACE M4 with this new code version. Particular attention is drawn to the effect of melt ejections on the pool temperature as well as to the evolution of solid volumetric fraction and of melt front progression during the MCCI. Finally, the application to a representative EPR specific sequence indicates that the principal objectives of the MCCI in the reactor pit can be safely fulfilled.
