Introdução: Existem poucos relatos correlacionando dados clínicos com a presença de carcinoma renal após o diagnóstico do tumor no exame de imagem. Objetivos: Analisar as características clínicas de pacientes submetidos à nefrectomia parcial (NP); correlacionar dados clínicos e da evolução no pós-operatório com a presença de carcinomas renais. Método: Estudo clínico observacional, retrospectivo, com 178 pacientes submetidos à NP entre 2009 a 2013. Foram avaliadas as características demográficas; morbidades: diabetes mellitus, hipertensão, doença cardiovascular; complicações do intra e pós-operatório e evolução. Os dados foram descritos em porcentagens, médias e desvio-padrão e significância estatística se p<0,05. Resultados: Foram analisados 178 pacientes de 54,0±13,4 anos, 61,2% do sexo masculino, 18,6% com tumores benignos e 81,4% com carcinomas renais. Entre os carcinomas, 69,7% foram de células claras e, entre os tumores benignos, 72,7% eram oncocitomas. A NP aberta foi realizada em 55,9% das vezes e em 44,1% por via laparoscópica. Após a cirurgia, 31,4 % necessitaram de unidade de terapia intensiva; 13,4 % apresentaram lesão renal aguda; 2,3 % alguma infecção; e 1,8% (n=3) foram a óbito após a alta. Entre as características, somente a obesidade e a redução do ritmo de filtração glomerular estimado (eRFG) em sete dias foi significativamente maior nos pacientes com carcinomas. Conclusões: Pacientes submetidos à NP eram predominantemente do sexo masculino e portadores de carcinomas de células claras. Pacientes com carcinomas eram mais obesos e tiveram maior redução do eRFG em sete dias do pós-operatório.

O trabalho traz algumas das unidades fraseológicas presentes no romance Cascalho (2011) do escritor Herberto Sales, que explicitam as marcas do léxico regional da região da Chapada Diamantina, na Bahia. Para tanto, a fundamentação teórico-metodológica está embasada na Fraseologia, ancorada nos trabalhos de Pottier (1977), Corpas Pastor (1996) e Aragão (2016). As unidades fraseológicas apresentadas elencam fórmulas representativas de diálogos de seus personagens. Essas  unidades são expressões de uso cotidiano que revelam as marcas linguísticas da comunidade, as quais redimensionam o estudo sociocultural de uma região. Revelam-se como uma fonte de informações sobre a linguagem regional que evidencia um uso particular daqueles que compartilham o espaço do garimpo. Com isso, é possível perceber valores ideológicos perpetuados e tradições cristalizadas tendo em vista que a língua deve ser estudada em sua relação mais estreita com a sociedade e a cultura. Os estudos voltados para a Fraseologia mostram a importância da relação entre língua e aspectos socioculturais. Nesse sentido, a análise proposta contribui para um maior conhecimento das marcas do léxico regional na Chapada Diamantina-BA.Palavras-chave: Lexicologia. Unidades fraseológicas. Cascalho.

Authors: Ziółkowska Wiesława
Published: April 2019

The purpose of the paper is to present a retrospective analysis of taxation in thecontext of public debt in the years 1995–2013. The author attempts to verify thehypothesis according to which there is correlation of various degrees of significanceand various directions between taxes and the debt of the general government sectorof the EU Member States. The study of those correlations was preceded by ananalysis that indicated tendencies to diminish tax burdens which was a result of„copying” tax policy and simultaneously increase sources and change character ofthe causes of increasing public debt. Out of 25 states where the correlation betweentwo major groups of taxes in GDP and public debt was proved, in 15 states thedimension of the interdependence was positive, while in the remaining 10 – negative.In the first group the lower (higher) tax burdens were, the lower (higher) thepublic debt was. Therefore it might be inferred that the tax rate below or abovewhich the budget income moves was not exceeded. As far as the remaining 10countries are concerned (those with negative correlation), it might be suggestedthat the critical point of decreasing (increasing) taxes below (above) which theincome drops was exceeded. Both the descriptive analysis of the indices and statisticalexamination make it possible to verify the adopted hypothesis positively,indicating simultaneously the necessity for further examination.

Etatyzacja gospodarki w okresie rządów komunistycznych w Polsce
Authors: Kaliński Janusz
Published: April 2019

In the years between 1944–1955 lasting foundations of the Polish economy were created based on communist dogma. In the mid-1950 s the so called socialized sector provided 75% of national income, however, multidirectional changes in economic policy in the following decades caused fluctuations in its importance. The changes were expressed by increases and decreases in the private sector share of jobs. As a result, the socialized sector was at its the peak in the 1970 s (86% share of the socialized sector in national income) only to fall to 81% of national income in the last year of communist rule. The dominance of the public sector was responsible for widespread mismanagement and social pathologies which led to the collapse of the economically inefficient system, preceded by a number of socio-political crises

The analysis of the EU strategy leads to two questions: why and how EU wants to engage this politically challenging region in the Post-Soviet Space. Regardless of satisfaction of EU bureaucracy with at best mediocre effects of undertaken actions, independent analysts perspective leads to a conclusion that EU does not use its own potential in the most effective way and its activity is sometimes more damaging than productive in terms of managing own assets as well as building its international reputation.
THE KITE RUNNER AND ITS FILM ADAPTATION AS A SITE OF TRANSLATION
Authors: ÜSTÜN KÜLÜNK Sema
Published: April 2019

In this study, the novel The Kite Runner (2003) by Khaled Hosseini and its filmic adaptation, presented with the same title, is analyzed. From a translational point of view, this intersemiotic study questions the references of the rendering of a verbal source text into a different semiotics system. In other words, the study dwells upon adaptation studies, discourse analysis, and intersemiotic translation with an interdisciplinary approach, and concentrates on the discursive references that govern the reception of the relevant works. Revealing how different agents of text production might turn the same source text into different target texts, the study views the novel as the source text and the filmic adaptation as the target text, and analyzes them from the dominant perspectives of the translation studies such as fidelity, intervention, manipulation within a comparative paradigm of source versus the target text.
The Impact of Misleadership on Poor Performance: A Study of Financial Institutions in Pakistan
Authors: Hamza Sahibzada Muhammad , Hassan Zubair
Published: April 2019

The main purpose of this research is to investigate the impact of misleadership on poor performance in the Pakistan financial institutions. This research is carried on the strategic and managerial employees of the one (1) private and one (1) foreign bank operated in Pakistan with an engagement of 200 employees as the sample respondents. The findings of the study indicates that missing, misguided and Machiavellian leadership has no significant impact of the poor performance in the studied context while only misinformed leadership in the cluster of the independent variables shows a significant positive impact on the poor performance in the financial institutions of Pakistan.  However, it is concluded that the proposed dimensions of Rayment & Smith (2010) misleadership framework does not significantly impact the poor performance in the financial institutions of Pakistan except the dimension of misinformed leadership. Further, it is recommended to examine new contexts with the engagement of a wider sample to find more accurate and generalize results for the investigated topic. Hence, this research will benefit the corporate managers and the research community with the new practicing dynamics of misleadership in today’s global corporate world.

Authors: Šabić Monika , Kučić Grgić Dajana , Vuković Domanovac Marija
Published: April 2019

As the world’s population and urbanization have significantly increased in the past few decades, the generation of municipal solid waste has accelerated on global scale. The biowaste disposal, which is an integral part of municipal waste, leads to leachate production. These kinds of wastewater are characterized by complex composition with very high concentrations of organic and inorganic pollution substances and toxicity, which may have harmful impact on the environment. This study investigated the physico-chemical and biological characterization of leachate from biowaste. The experiments were conducted in batch performance with initial concentration of leachate, expressed as chemical oxygen demand, 12.21 ± 0.46 g O2/L and pH value 4.05 ± 0.13. Obtained results showed that leachate from biowaste have high value of chemical oxygen demand, toxicity and low pH. Overall efficiency of the process of aerobic biodegradation was 89 %. The abundance of viable bacterial cells and development of activated sludge flocs during the experiment confirmed the biodegradability of leachate from biowaste.

Authors: Teixeira Alexandra , Hernández-Rodríguez Juan F. , Wu Lei , Oliveira Kevin , Kant Krishna , Piairo Paulina , Diéguez Lorena , Abalde-Cela Sara
Published: April 2019

Surface-enhanced Raman scattering (SERS) spectroscopy stands out due to its sensitivity, selectivity, and multiplex ability. The development of ready-to-use, simple, and low-cost SERS substrates is one of the main challenges of the field. In this paper, the intrinsic reproducibility of microfluidics technology was used for the fabrication of self-assembled nanoparticle structures over a paper film. The paper SERS substrates were fabricated by assembling anisotropic particles, gold nanostars (GNSs), and nanorods (NRs) onto paper to offer an extra enhancement to reach ultra-sensitive detection limits. A polydimethylsiloxane PDMS-paper hybrid device was used to control the drying kinetics of the nanoparticles over the paper substrate. This method allowed a high reproducibility and homogeneity of the fabrication of SERS substrates that reach limits of detection down to the picomolar range. This simple and low-cost fabrication of a paper-based sensing device was tested for the discrimination of different cell lineages.
Helical Twist and Rotational Forces in the Mitotic Spindle
Authors: Tolić Iva M. , Novak Maja , Pavin Nenad
Published: April 2019

The mitotic spindle segregates chromosomes into two daughter cells during cell division. This process relies on the precise regulation of forces acting on chromosomes as the cell progresses through mitosis. The forces in the spindle are difficult to directly measure using the available experimental techniques. Here, we review the ideas and recent advances of how forces can be determined from the spindle shape. By using these approaches, it has been shown that tension and compression coexist along a single kinetochore fiber, which are balanced by a bridging fiber between sister kinetochore fibers. An extension of this approach to three dimensions revealed that microtubule bundles have rich shapes, and extend not simply like meridians on the Earth’s surface but, rather, twisted in a helical manner. Such complex shapes are due to rotational forces, which, in addition to linear forces, act in the spindle and may be generated by motor proteins such as kinesin-5. These findings open new questions for future studies, to understand the mechanisms of rotational forces and reveal their biological roles in cells.

Published: April 2019

Supernumerary teeth (or hyperdontia) are teeth that exceed the normal number of deciduous or permanent teeth in the oral cavity. The occurrence of supernumerary teeth without any associated syndrome has been frequently reported and many case reports have been published. This article reports two rare cases of familial occurrence of multiple paramolars without the presence of any other syndrome for two consecutive generations. Limited cases of bilateral maxillary or mandibular paramolars have been reported. In addition, prevalence, classification, etiology, complications, diagnosis and therapeutic strategies that may be adopted when supernumeraries occur are discussed. A review of similar cases published in the literature is included as well.
Probabilistic Resumable Quantum Teleportation of a Two-Qubit Entangled State
Authors: Wang Zhan-Yun , Gou Yi-Tao , Hou Jin-Xing , Cao Li-Ke , Wang Xiao-Hui
Published: April 2019

We explicitly present a generalized quantum teleportation of a two-qubit entangled state protocol, which uses two pairs of partially entangled particles as quantum channel. We verify that the optimal probability of successful teleportation is determined by the smallest superposition coefficient of these partially entangled particles. However, the two-qubit entangled state to be teleported will be destroyed if teleportation fails. To solve this problem, we show a more sophisticated probabilistic resumable quantum teleportation scheme of a two-qubit entangled state, where the state to be teleported can be recovered by the sender when teleportation fails. Thus the information of the unknown state is retained during the process. Accordingly, we can repeat the teleportion process as many times as one has available quantum channels. Therefore, the quantum channels with weak entanglement can also be used to teleport unknown two-qubit entangled states successfully with a high number of repetitions, and for channels with strong entanglement only a small number of repetitions are required to guarantee successful teleportation.
Racial Inclusion in Education: An Australian Context
Authors: Fahd Kiran , Venkatraman Sitalakshmi
Published: April 2019

Racism in various forms exists worldwide. In Australia, racism is inextricably linked to the history of Australian immigrants and early setters. Although the Australian education system has adopted inclusive education, evidence shows several incidents of racial exclusion. With the public education system experiencing an increased cultural diversity in student population, schools are required to develop inclusive education policies. While policies related to disability inclusion have been in practice for many years, only recently has there been an increasing awareness of racial inclusion. This research paper explores the importance of racial inclusion in education by examining the causes and effects of racial exclusion in the Australian education context. This paper considers existing practices at the national level and in schools to explore racial discrimination. It identifies the factors contributing towards racism and proposes a framework employing key strategies at the macro, meso and micro levels to achieve racial inclusion in education. It also suggests opportunities based on research to strengthen the response against racism.
A Method for the Analysis of Interference from DME to ATCRBS in the Time Domain
Authors: Jiang Guofeng , Fan Yangyu , Yuan Hongbo , Yuan Pengliang
Published: April 2019

Analysis of the coexistence of two or more types of equipment is increasingly important. However, at present studies on the analysis method in the time domain are scant. Therefore, the aim of this paper is to explore the characteristics of signals and relations between interfering and desired signals in the time domain. Based on the periodicity of a signal, this paper presents a Periodic Pulse Overlap Method (PPOM). Using PPOM to analyze the interference from Distance Measuring Equipment (DME) to Air Traffic Control Radar Beacon System (ATCRBS) in the time domain, we obtain almost the same result as that based on the Monte Carlo Method (MCM). Furthermore, we discover the measures to reduce or even avoid interference, such as changing the Pulse Recurrence Frequency (PRF), adjusting the difference of initial time, and switching the operating modes of the equipment.

Published: April 2019

Based on the 0.5 μm GaAs enhancement/depletion (E/D) Pseudomorphic High Electron Mobility Transistor (pHEMT) process, a 7.5–9 GHz two-channel amplitude phase control multi-function chip (MFC) was developed successfully. The chip was integrated with a 6-bit digital phase shifter, a 6-bit digital attenuator, and a single pole single throw (SPST) switch in each channel. A design for the absorptive SPST switch is deployed to optimize the return loss and control channel array calibration. In the 8 dB and 16 dB attenuation bit, a switched-path-type topology is employed in order to obtain a good flatness of attenuation characteristic and achieve low additive phase shift. A 27-bit serial-to-parallel converter (SPC) was introduced to decrease the control lines and pads of the chip, and the power consumption was less than 70 mW. The measurement result shows that the insertion loss is less than −13 dB and the return loss is better than −19 dB. In both channels, the 64-state root mean square (RMS) errors of the phase shifter is less than 2° and the RMS parasitic amplitude error is less than 0.2 dB. The RMS attenuation error is less than 0.45 dB and the RMS parasitic phase error is less than 2.4°. The size of the chip is 3.5 mm × 4.5 mm.
Optimal Design of Wireless Charging Electric Bus System Based on Reinforcement Learning
Authors: Lee Hyukjoon , Ji Dongjin , Cho Dong-Ho
Published: April 2019

The design of conventional electric vehicles (EVs) is affected by numerous limitations, such as a short travel distance and long charging time. As one of the first wireless charging systems, the Online Electric Vehicle (OLEV) was developed to overcome the limitations of the current generation of EVs. Using wireless charging, an electric vehicle can be charged by power cables embedded in the road. In this paper, a model and algorithm for the optimal design of a wireless charging electric bus system is proposed. The model is built using a Markov decision process and is used to verify the optimal number of power cables, as well as optimal pickup capacity and battery capacity. Using reinforcement learning, the optimization problem of a wireless charging electric bus system in a diverse traffic environment is then solved. The numerical results show that the proposed algorithm maximizes average reward and minimizes total cost. We show the effectiveness of the proposed algorithm compared with obtaining the exact solution via mixed integer programming (MIP).
Large-Eddy Simulation-Based Study of Effect of Swell-Induced Pitch Motion on Wake-Flow Statistics and Power Extraction of Offshore Wind Turbines
Authors: Xiao Shuolin , Yang Di
Published: April 2019

In this study, the effects of ocean swell waves and swell-induced pitch motion on the wake-flow statistics and power extraction of floating wind turbines are numerically investigated. A hybrid numerical model coupling wind large-eddy (LES) and high-order spectral-wave simulations is employed to capture the effects of ocean swell waves on offshore wind. In the simulation, 3 × 3 floating wind turbines with prescribed pitch motions were modeled using the actuator disk model. The turbulence statistics and wind-power extraction rate for the floating turbines are quantified and compared to a reference case with fixed turbines. Statistical analysis based on the phase-average approach shows significant swell-correlated wind-velocity variations in both cases, and the swell-induced pitch motion of floating turbines is found to cause oscillations of wind-turbulence intensity and Reynolds stress, as well as an increase of vertical velocity variance in the near-wake region. Swells also cause periodic oscillation in extracted power density in the fixed turbine case, and the turbine pitch motion in the floating turbine case could further modulate this oscillation by shifting the phase dependence by about 180 degrees with respect to the swell-wave phase.
Classification of Special Days in Short-Term Load Forecasting: The Spanish Case Study
Authors: López Miguel , Sans Carlos , Valero Sergio , Senabre Carolina
Published: April 2019

Short-Term Load Forecasting is a very relevant aspect in managing, operating or participating an electric system. From system operators to energy producers and retailers knowing the electric demand in advance with high accuracy is a key feature for their business. The load series of a given system presents highly repetitive daily, weekly and yearly patterns. However, other factors like temperature or social events cause abnormalities in this otherwise periodic behavior. In order to develop an effective load forecasting system, it is necessary to understand and model these abnormalities because, in many cases, the higher forecasting error typical of these special days is linked to the larger part of the losses related to load forecasting. This paper focuses on the effect that several types of special days have on the load curve and how important it is to model these behaviors in detail. The paper analyzes the Spanish national system and it uses linear regression to model the effect that social events like holidays or festive periods have on the load curve. The results presented in this paper show that a large classification of events is needed in order to accurately model all the events that may occur in a 7-year period.

Authors: Lamas M. I. , Rodriguez C. G.
Published: April 2019

In order to reduce NOx emissions in internal combustion engines, the present work analyzes a measurement which consists of injecting ammonia directly into the combustion chamber. A commercial compression ignition engine fueled with a hydrogen-diesel blend was studied numerically. It was verified that the flow rate shape in which the ammonia was injected, particularly rectangular, triangular, or parabolic, as well as the injection duration had an important influence on NOx reduction. A 11.4% improvement in NOx reduction, corresponding to an overall reduction of 78.2% in NOx, was found for parabolic injection shape and 1º injection duration. The effect on carbon dioxide, carbon monoxide, and hydrocarbon emissions, as well as brake-specific consumption, was negligible.
Research and Modeling of Photovoltaic Array Channel Noise Characteristics

Published: April 2019

The photovoltaic array can be used as a medium for carrier communication to realize monitoring of photovoltaic components. Photovoltaic array channel noise, especially the pulse-type noise therein, seriously interferes carrier communication, so it is necessary to grasp the characteristics of the photovoltaic array channel noise. Photovoltaic array channel noise modeling is a key process when conducting anti-noise immunity tests of monitoring equipment. Based on the time-domain waveform of photovoltaic series channel noise which is measured in a photovoltaic power station, this paper proposes a photovoltaic array noise modeling method of Wavelet Peak-Type Markov chain, and studies the influence on modeling accuracy when different mother wavelets are adopted for modeling. From the simulation results, root mean square errors of the predicted output for Haar, Biorthogonal and Daubechies wavelet-based function modeling case are 0.9614 V, 1.4915 V and 0.7928 V, respectively, validating that Daubechies wavelet-based function is the best wavelet-based function of modeling. In the case that the peak of original noise reaches 20 V, the predicted mean absolute error of this model is only 0.4926 V, which not only verifies the applicability of the Wavelet Peak-Type Markov chain model to the photovoltaic array channel noise, but also verifies the applicability to the pulse-type noise.

To prepare for the future high penetration level of renewable energy sources, the power grid’s technical boundaries/constraints for the correct operation of powerelectronics interfaced devices need to be further examined and defined. This paper investigates the challenge of integrating Voltage Source Converters (VSC) into low inertia power grids, where the system frequency can vary rapidly due to the low kinetic energy buffer available, which used to be provided by the rotational inertia of synchronous generators. The impact of rate of change of frequency (ROCOF) on the PLL dynamics and its subsequent influence on the VSC power stage output is explained. The Bonaire island network is presented as case study. The performance of the VSC is analyzed under a fast ROCOF event, which is triggered by a short circuit fault. A down-scaled experiment is used to validate the Bonaire island network simulation results. It shows that the phase angle error measured by the synchronous-reference frame phase-locked loop (SRF-PLL) is proportional to the slope of the ROCOF and inversely proportional to its controller integral gain constant.

Published: April 2019

Thermochemical-technology has high potential for utilizing surplus heat from industrial processes and renewables. This paper examines the economic potential and thermochemical-technology behavior at a network level. The city of Hasselt (Belgium), was chosen as a case study for technology application due to its typical mid-European urban structure. An integrated heating system was proposed which transports energy potential from available surplus-heat sources to the demand side over long distances by a thermochemical-district-heating network, which serves for building heating with heat-pump assistance. A dynamic simulation model of the thermochemical-technology was developed using the experiments and Hasselt data to determine the technology’s energy performance. To examine the technology’s feasibility in the context of a large district energy network, an economic and environmental evaluation of the thermochemical-technology was performed. To compare key economic parameters between our integrated technology and other heating systems a sensitivity analysis to identify favorable market-conditions for wider deployment of the proposed technology was performed. The simulations indicated a 72% reduction of heat-pump heating energy usage as a benefit of the thermochemical system. Network pumping-energy and thermochemical-fluid mass were found via simulation to be 80 kWh and 300 tons, respectively. In comparison to domestic-gas-boilers, the proposed technology shows 95% lower carbon emissions, however at 37% higher annualized cost.

Demand response (DR) is known as a key solution in modern power systems and electricity markets for mitigating wind power uncertainties. However, effective incorporation of DR into power system operation scheduling needs knowledge of the price–elastic demand curve that relies on several factors such as estimation of a customer’s elasticity as well as their participation level in DR programs. To overcome this challenge, this paper proposes a novel autonomous DR scheme without prediction of the price–elastic demand curve so that the DR providers apply their selected load profiles ranked in the high priority to the independent system operator (ISO). The energy and reserve markets clearing procedures have been run by using a multi-objective decision-making framework. In fact, its objective function includes the operation cost and the customer’s disutility based on the final individual load profile for each DR provider. A two-stage stochastic model is implemented to solve this scheduling problem, which is a mixed-integer linear programming approach. The presented approach is tested on a modified IEEE 24-bus system. The performance of the proposed model is successfully evaluated from economic, technical and wind power integration aspects from the ISO viewpoint.

Animal growth and development are regulated by long non-coding RNAs (lncRNAs). However, the functions of lncRNAs in regulating cashmere fineness are poorly understood. To identify the key lncRNAs that are related to cashmere fineness in skin, we have collected skin samples of Liaoning cashmere goats (LCG) and Inner Mongolia cashmere goats (MCG) in the anagen phase, and have performed RNA sequencing (RNA-seq) approach on these samples. The high-throughput sequencing and bioinformatics analyses identified 437 novel lncRNAs, including 93 differentially expressed lncRNAs. We also identified 3084 differentially expressed messenger RNAs (mRNAs) out of 27,947 mRNAs. Gene ontology (GO) analyses of lncRNAs and target genes in cis show a predominant enrichment of targets that are related to intermediate filament and intermediate filament cytoskeleton. According to the Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis, sphingolipid metabolism is a significant pathway for lncRNA targets. In addition, this is the first report to reveal the possible lncRNA–mRNA regulatory network for cashmere fineness in cashmere goats. We also found that lncRNA XLOC_008679 and its target gene, KRT35, may be related to cashmere fineness in the anagen phase. The characterization and expression analyses of lncRNAs will facilitate future studies on the potential value of fiber development in LCG.

Published: April 2019

Objectives: Using the Andersen’s Behavioral Model of Health Services Use, we explored social, behavioral, and health factors that are associated with emergency department (ED) utilization among underserved African American (AA) older adults in one of the most economically disadvantaged urban areas in South Los Angeles, California. Methods: This cross-sectional study recruited a convenience sample of 609 non-institutionalized AA older adults (age ≥ 65 years) from South Los Angeles, California. Participants were interviewed for demographic factors, self-rated health, chronic medication conditions (CMCs), pain, depressive symptoms, access to care, and continuity of care. Outcomes included 1 or 2+ ED visits in the last 12 months. Polynomial regression was used for data analysis. Results: Almost 41% of participants were treated at an ED during the last 12 months. In all, 27% of participants attended an ED once and 14% two or more times. Half of those with 6+ chronic conditions reported being treated at an ED once; one quarter at least twice. Factors that predicted no ED visit were male gender (OR = 0.50, 95% CI = 0.29–0.85), higher continuity of medical care (OR = 1.55, 95% CI = 1.04–2.31), individuals with two CMCs or less (OR = 2.61 (1.03–6.59), second tertile of pain severity (OR = 2.80, 95% CI = 1.36–5.73). Factors that predicted only one ED visit were male gender (OR = 0.45, 95% CI = 0.25–0.82), higher continuity of medical care (OR = 1.39, 95% CI = 1.01–2.15) and second tertile of pain severity (OR = 2.42, 95% CI = 1.13–5.19). Conclusions: This study documented that a lack of continuity of care for individuals with multiple chronic conditions leads to a higher rate of ED presentations. The results are significant given that ED visits may contribute to health disparities among AA older adults. Future research should examine whether case management decreases ED utilization among underserved AA older adults with multiple chronic conditions and/or severe pain. To explore the generalizability of these findings, the study should be repeated in other settings.
Does the Electronic Health Card for Asylum Seekers Lead to an Excessive Use of the Health System? Results of a Survey in Two Municipalities of the German Ruhr Area

Background: The initial and intermediate-term access of refugees to healthcare in Germany is limited. A previous study showed that the obligation to request healthcare vouchers at the social security offices decreases the asylum seekers’ consultation rate of ambulant physicians. The introduction of the Electronic Health Insurance Card (EHIC) for asylum seekers is considered skeptically by some municipalities and federal states, among other reasons due to the fear of an overuse of health care services by asylum seekers. The aim of this study is to further evaluate the data of the authors’ initial study with a new focus on inpatient care as well as a differentiation of the ambulant consultation rate into general practitioners and outpatient specialists. Methods: The now-differentiated consultation rate of the initial study as well as the asylum seekers’ use of inpatient care are compared to the values of the sex- and age-corrected autochthonous population as given by the German Health Interview and Examination Survey for Adults (DEGS1). A mean difference test (student’s t-test) is used for comparison and significance testing. Results: Asylum seekers who were in possession of the EHIC were significantly less likely to visit their ambulant general practitioners and specialists than the German autochthonous population. Simultaneously, this difference is partly compensated for by their more frequent use of impatient care. Conclusions: There is no indication that the EHIC leads to an overuse of healthcare services.
