Authors: Davudov Mahammad , Rahimov Chingiz , Ahmadov Elchin , Irannejad Farinaz , Qurbanov Vugar
Published: November 2017

Background: Chondroblastoma is one of the rare diseases. It often localizes in the epiphysis of the long bones. It is very rare in the flat bones (20 % in men), especially in the facial bones and TMJ. Usually it is found in young people under the age of 20 and its rate in women is 2 times lesser than in men. Its etiology is still unknown. Case report: Patient M.P., a 45 years old male, applied to Clinic with limited mouth opening and swelling on the right periauricular masticatory region. The tumor was removed by surgical operation under the general anesthesia, sent to pathohistologic analysis, and the diagnosis of chondroblastoma was confirmed. Conclusion: Treatment has been successful and no recurrent findings or postoperative complications, including functional restrictions, have occurred in the one year following the complete tumor excision.

Published: November 2017

Silphium perfoliatum L. is a perennial and flowering crop that has been investigated in recent years for its potential as an energy plant, particularly for biogas production. A stand establishment by sowing of seeds is complicated, owing to the low germination capacity of untreated S. perfoliatum L. seeds. Consequently, germination experiments were carried out with two- to four-factor levels to determine the effect of selected factors (medium, pretreatment, light, temperature, prechilling) on dormancy and germination of S. perfoliatum L. seeds and to achieve maximum germination rate. All factors had a highly significant effect on germination. Germination experiments displayed a primary and physiological dormancy. Germination could be significantly increased by using a 0.05% GA3 solution during the imbibition phase, a light–dark cycle, alternating temperatures between 20°C and 30°C, and a wet stratification for seven days at 0°C. The experiments helped to fully exploit the germination potential and to develop a germination test method for S. perfoliatum L.

Published: November 2017

The development of seeds at various positions in the pod is asynchronous. Thus, the differences of seed dry mass production because of environmental conditions may depend on the cultivar type, type of inoculants and interrelations between seeds per pod, pods per plant or seeds per plant. Presently, a mathematical description of pea seed categorisation is missing. The aim of the study was the assessment of two groups of variables (quantitative and qualitative) for pea seed weight categorisation by ordinal regression model. Year, cultivar and inoculant constituted the first group (qualitative variables), whilst seeds per pod, the pods per plant and seeds per plant (quantitative variables) were entered as covariates in the ordinal regression model. According to the ordinal regression model variables, seeds per pod, pods per plant, seeds per plant, year and cultivar are meaningful predictors of the seed mass categories. However, the variable inoculant is marginally significant.
A simplified maturity index to quantify the development stage of perennial ryegrass (Lolium perenne L.) and its relationship with yield and nutritive value
Authors: Salama Heba , Loesche Marc , Herrmann Antje , Taube Friedhelm , Gierus Martin
Published: November 2017

Plant maturity substantially influences the yield and quality performance of grasses. Grass phenology is often not considered objectively to evaluate the new genotypes prior to registration. Measuring the mean stage by count (MSC) is time consuming, and simplified approaches are, therefore, required. Twenty diploid, intermediate heading Lolium perenne L. genotypes were evaluated in a 2-year field study in Northern Germany for yield and the content of Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), Acid Detergent Lignin (ADL), and digestible organic matter (DOM). Data from the first and second cut, each comprising three sampling dates, were included in this study. A simplified maturity index (SMI8), expressing the percentage of tillers at or beyond the boot stage, from MSC was derived. This index resulted in similar correlations with yield and quality parameters compared to MSC but is easier to use and less laborious. The SMI8 reduced the variations among genotypes, as for the first cut NDF and ADF content, where the genotype effect disappeared after considering SMI8 as the covariable. Moreover, the ranking of the genotypes was slightly modified for most studied traits, indicating that a large part of the variations in the studied parameters was caused by variations in maturity.

Authors: Hamed Rasha Hamdy
Published: November 2017

Aim

This trial aimed to determine wether postoperative radioactive iodine(RAI) associated with a survival benefit among intermediate-risk Papillary Thyroid Cancer patients or not.

Methods

this study is a retrospective study of intermediate-risk papillary thyroid cancer patients that were treated with or without post operative RAI from 1st January 2002 till 1st January 2012. Overall survival (OS) and multivariate regression analyses were measured for all patients.

Results

100 patients were included in this trial : 70 patients received postoperative RAI and 30 patients did not. The mean follow-up time was 7.1 (4.8 -15.1 years), and a median survival time could not be estimated. Overall survival at 10 years was 96% in the RAI vs 93% in the group without RAI (P < .001). RAI reduced risk of death by a 27% [hazard risk (HR) 0.73, confidence interval (CI) 0.64 - 0.84, P < .001]. Older patient age, male gende, larger tumor size, multifocal tumors, lymph node metastases, aggressive histology, vascular invasion, positive surgical margin, minimal extrathyroidal extension and absence of postoperative RAI were accompanied by compromised OS (all P ≤ .001).

Conclusion

This representative study addresses the survival advantage of RAI for with intermediate risk PTC patients but conducting of large prospective randomized controlled trial is still warranted.
Succession of ground beetle (Coleoptera: Carabidae) communities after windthrow disturbance in a montane Norway spruce forest in the Hrubý Jeseník Mts. (Czech Republic)
Authors: Kašák Josef , Foit Jiří , Hučín Marek
Published: November 2017

Wind disturbances are a key factor that is significantly involved in the life cycle of natural boreomontane coniferous forests. As most of these forests are currently intensively managed, we have limited knowledge on succession following natural disturbance. Succession in a Norway spruce stand after a windthrow event was studied using ground beetles as model bioindication taxa in the Hrubý Jeseník Mts. (Czech Republic). The study documented that the composition of ground beetle communities was significantly associated with stand age and its microclimatic parameters (particularly the minimal temperature and average and minimal humidity). Forest species including prey specialists, hygrophilous species, as well as habitat generalists were the most abundant in the mature stand, where the forest had the highest humidity and the least profound minimal temperatures. In contrast, open-habitat species, including euryoecious species and relict species of higher elevations, reached their highest abundances in clearing shortly after the windthrow. In clearing the humidity was lower and the temperature fluctuated significantly (the lowest minimal temperatures). Ground beetles, including forest species, were the least abundant in young stands (10 and 20 years after windthrow). We conclude that old stands are of particular importance because they harbour the highest abundance and diversity of ground beetles with various ecological requirements. Natural wind disturbances are important as well since they increase diversity by enabling the occurrence of many non-forest species. Hence, a mosaic of stands of different ages with a sufficient proportion of old stands should be maintained when managing montane coniferous forests.
Economic value production of trees as a criterion of their maturity in an uneven-aged forest
Authors: Petráš Rudolf , Mecko Julian , Kulla Ladislav
Published: November 2017

Tree maturity of the four main tree species that are most frequent in the uneven-aged forests of the Western Carpathians was analysed. The maturity was determined on the base of the economic value production in relation to tree diameter. We derived mean timber values of spruce, fir, pine, and beech trees (€ m−3) depending on their diameters, quality and stem damage, and in the case of beech also depending on tree age. The assortment structure was calculated using the models of tree assortment tables that account for the stated tree parameters. The assortment prices were taken from the price list of logs in assortment and diameter classes of the Forests of the Slovak Republic, state enterprise, for the year 2016. Trees are mature when their mean timber monetary value is at maximum. Results show, that the highest mean value production of the majority of beech trees of average and above-average stem quality is 70 - 80 € m−3 for trees with diameters between 45 and 55 cm. Monetary values of spruce and fir trees with diameters above 60 to 90 cm are 80 - 95 € m−3, while the monetary values of pine trees with the same diameters are approximately 70 - 115 € m−3. The value production of trees is reduced if the stems are of worse quality or damaged, but in the case of beech it also decreases with greater diameter or tree age.
Reconstructing past forest status using inventory and tree ring data to support uneven-aged forest management

Published: November 2017

The decision to change forest management system from the traditional even-aged to the selection one based on statistical inventory is often limited by a missing previous inventory. To avoid this issue, we used available forest inventory data from ca 2 000 ha of mixed uneven-aged beech-fir-spruce-pine forest and tree ring data from 831 trees to reconstruct forest status from one decade ago. For this purpose, we have created three sets of species-specific models: 1) diameter-stump models to reconstruct the diameter of missing trees, 2) diameter-increment models based on tree ring data to estimate past diameters, and 3) height-diameter models to estimate past tree heights. This approach has allowed us to completely reconstruct the state of the forest as it was ten years ago and use the results as a substitution for a previously missing inventory.

Published: November 2017

Process-based vegetation models are crucial tools to better understand biosphere-atmosphere exchanges and ecophysiological responses to climate change. In this contribution the performance of two global dynamic vegetation models, i.e. CARAIB and ISBACC, and one stand-scale forest model, i.e. 4C, was compared to long-term observed net ecosystem carbon exchange (NEE) time series from eddy covariance monitoring stations at three old-grown European beech (Fagus sylvatica L.) forest stands. Residual analysis, wavelet analysis and singular spectrum analysis were used beside conventional scalar statistical measures to assess model performance with the aim of defining future targets for model improvement. We found that the most important errors for all three models occurred at the edges of the observed NEE distribution and the model errors were correlated with environmental variables on a daily scale. These observations point to possible projection issues under more extreme future climate conditions. Recurrent patterns in the residuals over the course of the year were linked to the approach to simulate phenology and physiological evolution during leaf development and senescence. Substantial model errors occurred on the multi-annual time scale, possibly caused by the lack of inclusion of management actions and disturbances. Other crucial processes defined were the forest structure and the vertical light partitioning through the canopy. Further, model errors were shown not to be transmitted from one time scale to another. We proved that models should be evaluated across multiple sites, preferably using multiple evaluation methods, to identify processes that request reconsideration.
ANA Testing: What should we know about the methods, indication and interpretation?
Authors: Au Elaine Yuen Ling
Published: November 2017

Though ANA is a common test requested in several settings, one may not be aware of the potential traps for interpretation. Nowadays, there is a trend for autoantibodies diagnostics to move from traditional time honored manual methods to high throughput automated platforms. Nevertheless, the clinical significance and assay performance characteristics may be different from those “historical” methods. Though indirect immunofluorescence is the gold standard method for ANA tests, different laboratories vary in the slides (from different cell lines and commercial source, e.g., Hep 2, Hep 2000, etc.), screening dilutions, terminology, reporting format and expertise. Hence, discrepancy in results among different laboratories is not uncommon and could be confusing. Knowing the assay characteristic and limitations helps proper results interpretation and facilitate patient’s management. Indeed, the titer and pattern by indirect immunofluorescence do provide valuable information in screening patients. In particular, DFS pattern with the associated anti-DFS70 antibodies has been shown to have a role to risk stratify cases referred for suspected autoimmune rheumatic disease.

Transmission Performance and Cost Analysis of Multi-Carrier-based Wavelength Division Multiplexed Passive Optical Access Network
Authors: Khan Jahanzeb , Khan Yousaf , Ullah Salamat , Shafique Querishi Shahryar
Published: November 2017

Multi-tone-based wavelength division multiplexed passive optical networks are considered to provide cost-effective access network solution. We analysed and revealed the transmission performance, power budget concern and the cost investigation of the multi-tone-based WDM PON. A differential phase shift keying and re-modulated return to zero on/off keying signals for downlink and uplink, respectively, are transmitted via a single-mode fibre. The transmission performance of the proposed architecture is analysed using key parameters of bit error rate and optical signal to noise ratio using different data rates and channel spacing. The simulation results are in agreement with the theoretical analysis. The power budget is calculated for both upstream and downstream data signals showing excellent system margins for any unseen losses. The proposed setup is also analysed in terms of cost to prove it the cost-effective solution for the next-generation optical access networks.

A Description of Tucumán Spanish Intonation in Argentina
Authors: Terán Virginia , Ortega-Llebaria Marta
Published: November 2017

This paper documents for the first time the intonation system of Tucumán Spanish, an understudied variety of Argentinian Spanish. Semi-spontaneous speech illustrating the intonation of main sentence types, i.e. broad focus statements, partial and absolute interrogatives, and imperatives and vocatives, was elicited from 31 native speakers of Tucumán Spanish via an adapted version of the Argentinian Intonation Survey (Prieto and Roseano, 2009-2013). The two authors listened to the recordings and transcribed them using the Tones and Break Indexes conventions (ToBI) (Beckman et al. 2002, Prieto and Roseano 2010, Hualde and Prieto 2015). Transcriptions of prenuclear and nuclear configurations together with their respective frequencies allowed both an appreciation of the most used configurations within each sentence type along with detailed variation at the phonetic level. For example, yes/no questions were consistently realized with a low nuclear pitch accent L* and an ascending boundary tone. However, there was variation in the height of the boundary tones yielding the frequent contour L* ¡H%, and the less frequent L* H%. Altogether, these detailed patterns document the systematic phonetic variation of the intonation system of TS and provide a basis for future research to determine the phonological status of this variation.
Physicochemical Stability of Reconstituted Decitabine (Dacogen®) Solutions and Ready-to-Administer Infusion Bags when Stored Refrigerated or Frozen
Authors: Kim Sun Hee , Heeb Rita Marina , Krämer Irene
Published: November 2017

Background

Profound knowledge about the physicochemical stability is necessary in order to determine the “beyond-use-dates” of ready-to-administer preparations after reconstitution and dilution. This is especially true for unstable azanucleoside drugs like decitabine. The aim of this study was to determine the physicochemical stability of decitabine after reconstitution and dilution of Dacogen

Methods

To determine the stability of frozen Dacogen

To determine the stability of reconstituted Dacogen

Diluted Dacogen

Decitabine concentrations were determined at 0, 5, 8, 12, 24 and 48 hours after preparation. The pH-values were determined at 0, 8, 24 and 48 hours. Each sample was assayed by a validated stability-indicating reversed-phase high-performance liquid chromatography (RP-HPLC) assay with photodiode array detection.

Results

When test solutions of reconstituted Dacogen

In reconstituted test solutions in glass vials and in diluted test solutions in infusion bags stored under refrigeration decitabine concentrations remained above 90 % of the initial concentration for 12 hours and 24 hours, respectively. Several peaks of degradation products were observed which explicitly increased over time.

In all test solutions the pH-values amounted to pH 7 and remained unchanged. No particulate matter and no colour changes were observed over the test period.

Conclusions

Introduction. It seems that there is a relationship between small intestinal bacterial overgrowth (SIBO) and non-alcoholic fatty liver disease (NAFLD). The main objective of this study was to evaluate the prevalence of SIBO among NAFLD patients.

Methods. In this descriptive-analytical cross-sectional study, 98 eligible NAFLD patients were evaluated for SIBO using hydrogen breath test (HBT). They were divided into SIBO-positive and SIBO-negative groups. Demographic, clinical, and laboratory data were obtained.

Results. Based on the HBT, 38 patients (39%) had bacteria overgrowth. There were no significant differences between SIBO-positive and SIBO-negative regarding demographic data and BMI classification (P > 0.05). Biochemical variables, the results of abdominal ultrasound, and liver elastography did not show any significant difference between SIBO-positive and SIBO-negative patients (P > 0.05). Patients with SIBO were found to have higher rates of bloating, while abdominal pain was more prevalent in SIBO-negative patients (P < 0.001).

Conclusions. SIBO is prevalent in NAFLD and associated with bloating in these patients. Further studies are necessary to elucidate if therapeutic manipulation of gut microbiota reduces the risk of NAFLD, fibrosis, and liver cirrhosis.

Published: November 2017

Pregnancy is a period marked by profound changes in a woman’s hormonal status and metabolism, including the development of a carbohydrate-intolerant state. Gestational diabetes mellitus (GDM) is defined as any degree of glucose intolerance with onset or first recognition during pregnancy.

The aim of this study was to estimate and analyse the parameters of glycaemic control during pregnancy. We stratified patients into the following three groups according to OGTT results: normal glucose tolerance (NTG), gestational impaired glucose tolerance (GIGT) and GDM.

We investigated 92 pregnant women, diagnosed with vital and desired pregnancy up to 12 weeks of gestation, who had signed informed consent forms. Among them, 7 pregnant women had a spontaneous abortion, while 8 pregnant women dropped out, so a total of 77 pregnant women completed the trial. Most of the women examined had no risk factors (48%), while 35% of the women had one risk factor. The current study demonstrates that normal glucose tolerance was shown in 59 (76.6%) participants, while some form of glucose intolerance (GIGT or GDM) was shown in 18 (23.4%) patients. Our findings revealed an increase in glucose intolerance with advancing pregnancy (in the second and third trimester). In conclusion, we demonstrate that the difference in the quality of glycaemic control during pregnancy is manifested in the second and third trimester, until it manifests in the first trimester. These findings underpin the clinical significance of discovering GDM.

Published: November 2017

The article deals with the problem of the dispersion of ordinal variables. At first, it specifies the very concept of dispersion for this type of scale. Then some of the most known measures that fit to the concept of ordinal variation are recalled. They are constructed with two different types of statistical models: using loss functions and using distance functions. Finally, a new approach, which is the use of an axiomatic method for the construction of a dispersion measure, is proposed. Some relations and comparisons between different measures and between different approaches are shown.

In the first part are presented axiological sources of the principles of proportionality and progressive and degressive proportionality and the history of degressively proportional apportionments of seats in the European Parliament. The main part of the article is devoted to the formulation of proposals for strict formal definition of degressive and progressive proportionality, and a description of the method of apportionment of seats in the European Parliament based on the strict definition of degressive proportionality and maintaining maximum compatibility with former apportionments adopted in multilateral negotiations. The last part of the article consists of a discussion of the possibilities of adopting the concept of progressive proportionality in the analysis of the functioning of parliamentary electoral systems.
DECISION STRATEGIES AND COGNITIVE ADAPTATIONS TO ECOLOGY
Authors: Poleszczuk Jan
Published: November 2017

In this paper, I discuss the concept of adaptive rationality. I present a simple model of ecology and the set of decision rules. The basic structure of the process of cognitive adaptation to ecology is described as a structure comprising (1) perceptual space, (2) a function valuating perceived items, (3) a set of available decision rules and (4) the adaptation process - identification and selection of the best strategies in given ecological conditions. The presented model of ecosystem allows a conclusion that completely opposite strategies may be compatible with the assumption of adaptive rationality.
GENDER DIFFERENCES IN HIGH-STAKES MATHS TESTING. FINDINGS FROM POLAND
Authors: Zawistowska Alicja
Published: November 2017

The present research investigates gender gaps in the results of secondary school exit exams (Matura) in mathematics in Poland in 2015. The analysis shows that, in the basic level exam, males are highly overrepresented at the upper end of the score distribution. The same pattern did not exist in the extended-level Matura. Two explanations are offered here. The differences are driven by gender self-selection in high school programs. Students who decide on maths-related tracks have more maths lessons than other students. Secondly, a student who takes the extended Matura also has to take the basic Matura exam. As a result, the population of students taking the basic Matura is highly differentiated in terms of maths competence and motivation. Additionally, the analysis of differential item functioning (DIF) shows that only a few items were flagged as having DIF.
TERRITORIAL TRANSFER OF KNOWLEDGE IN TERMS OF CREATIVE DESTRUCTION
Authors: Ciborowski Robert
Published: November 2017

‘Creative destruction’ is one of the most important analytical tools, taking into consideration both the economic and sociological characteristics of capitalist society. According to Schumpeter, in the long term, evolution gives rise to economic development resulting from batches of innovative solutions, leading to improvements in the standard of living. The innovation activity of firms is based on supply-side factors, hence it is large enterprises that excel in innovation since they strive to achieve a monopoly market position and above-average profits. Schumpeter attempts to combine two elements: the spread of monopolies and the continuation of economic development, both occurring through innovation, which is far more important than price competition. The Schumpeterian ‘creative destruction’ permeates the main aspects of macroeconomic activity, not only in the long term, but also in the area of economic fluctuations, structural changes, or the functioning of markets. As a result, it becomes a factor determining changes in the economic order. The purpose of this paper is to analyse the role of territories in the process of creating and using knowledge and its impact on the economic efficiency of the companies which function within their boundaries. Regional cooperation increases the involvement of business entities in innovation activities, which translates into higher competitiveness of firms. Moreover, the awareness of the necessity of cooperation and use of innovation capital tends to grow.
Exchange rate misalignment and economic growth: evidence from nonlinear panel cointegration and granger causality tests
Authors: Tipoy Christian K. , Breitenbach Marthinus C. , Zerihun Mulatu F.
Published: November 2017

We analyse the impact of exchange rate misalignment on economic growth for a sample of emerging economies from 1970 to 2014 using a panel smooth transition regression vector error correction model. Besides, we provide a granger causality test conducted in a non-linear framework. We find that a rise in misalignment increases significantly the output in the short-run when currencies are close to equilibrium. When they are highly misaligned, the impact on growth is reduced. However, no significant impact of output on misalignment was found in the short-run. We provide evidence that misalignment granger causes the output at any given level of misalignment both in the short and long-run. Weaker granger causality was found between output and misalignment. This raises some important policy implications. Although emerging economies can use undervaluation as a growth strategy, the benefits are smaller when currencies are highly undervalued. There is, therefore, an incentive to keep exchange rates closer to their equilibrium.
Novel monolithic pendulum tiltmeter with Nanorad resolution
Authors: Kühnel Michael , Fern Florian , Fröhlich Thomas
Published: November 2017

Tiltmeters with nanorad resolution in a large measurement range of ±9 mrad (±0.5○) and
a very good linearity have been developed at the Technische Universität Ilmenau in the recent years. The working principle
bases on the measurement of tilt-dependent lateral forces, which act on a hanging force-compensated weigh cell (precision
balance). The disadvantage is the relatively complex design of the weigh cell mechanics, the large dead weight and the
high manufacturing costs.

For that reason a simplified tiltmeter was developed. It only consists of two components: a monolithic pendulum mechanics
and an optical position sensor. State of the art pendulum tiltmeters contain several components that are linked by
screwed, clamped or glued connections. This can limit the long-term-, temperature- or humidity stability of the tiltmeter.

The position sensor achieves a standard deviation of ∼ 50 pm at a measuring frequency of
10 Hz. The length of the pendulum amounts to 0.1 m, its mass is ∼ 62 g. With this
combination, the theoretical standard deviation of the tilt measurement should result to ∼ 0.6 nrad at
10 Hz measuring frequency and was approved by measurements. The measurement range of the new monolithic
tiltmeter amounts ∼ ±2 mrad.
Un-locking unsustainable tourism destination paths: the role of voluntary compliance of tourism businesses with sustainability certification on the island of Rügen
Authors: Panzer-Krause Sabine
Published: November 2017

During the last 150 years the island of Rügen has developed into a mass tourism destination resulting in a continuing pressure on the island’s environment and cultural heritage. Highlighting the need for a stronger consideration of ecological and social-cultural aspects of development in economic geography research, this paper uses an evolutionary approach to identify lock-ins in the Rügen tourism industry that hamper a sustainability transition and analyzes the role voluntary compliance of tourism businesses with sustainability certification can play to break away from these development paths. Focusing on the concepts of green growth and degrowth the paper provides indications that particularly in protected areas that are confronted with acceptance problems, an efficiency-driven green growth approach guided by a spirit of sustainability can be the basis for moving towards more sustainable modes of development. However, the study raises the question of time frames for regional sustainability transitions and the parameters these depend on.
Modeling of Anisotropic Behavior of Aluminum Alloys to Investigate Ductile Fracture for the Improved Formability in the Upsetting Process
Authors: Chirala H. K. , Davidson M. J. , Srinivasarao G. , Srinivasaraju P.
Published: November 2017

In the bulk-forming operations, such as upsetting, the billets upon severe plastic deformation will fracture on reaching the threshold fracture stress. The fracture initiation and progression depends on the friction, height-to-diameter ratios (h/d), and the strength of the material. The anisotropic behavior of material is another issue that should be taken into consideration while designing the process. Macro fracture criteria, such as normalized Cockcroft, Brozzo, McClintock, and Oyane, can be better utilized to predict the fracture initiation. The Hill–von Mises criterion that incorporates the anisotropy factors (R0 and R90) was correlated with the macro failure criterion to evaluate the critical damage factor values at failure strain under plane stress condition. The process parameters, namely, friction, height-to-diameter ratios (h/d), and the strength of the material were considered, and the upsetting process was optimized using Taguchi’s design of experiment techniques with less anisotropy as desired output. After identifying the optimum result, an analysis of variance (ANOVA) analysis was performed and the contribution of each factor responsible for failure and anisotropy was also noted.

Patent foramen ovale (PFO) is a common congenital abnormality with a high prevalence of approximately 25 % in the general population and an even higher incidence of about 40 % in the cryptogenic stroke population. PFO closure in cryptogenic stroke patients as a treatment modality for the secondary prevention of recurrent stroke has been much debated and studied. Several completed randomized clinical trials sought to answer the question of whether PFO closure is beneficial for cryptogenic stroke patients. Until the most recent of these trials, no significant benefit had been demonstrated. Based on newer evidence, in October 2016 the US Food and Drug Administration approved the first dedicated closure device for PFO. This review article describes the association between PFO and cryptogenic stroke, reviews current diagnostic modalities of PFO assessment, discusses management approaches, and reviews randomized clinical trials, practice guidelines, and consensus statements. Associations between PFO and other conditions such as migraine headaches, platypnea-orthodeoxia syndrome, and decompression sickness in divers are also briefly reviewed.
Clinical Significance of Idiopathic Frequent Premature Ventricular Complexes

Premature ventricular complexes (PVCs) in the absence of underlying structural heart disease are often benign. Most patients with this type of disease have an uneventful clinical course and can be treated based on symptoms. However, there exists a subset of patients with frequent PVCs that may develop cardiomyopathy and heart failure. This review describes the mechanisms and potential adverse effects of frequent PVCs, the prognosis and risk stratification of patients based on the nature and quantity of PVCs, and the clinical management and outcomes of these patients.

Cardiovascular disease is the leading cause of death in the US. Several new pharmacologic therapies have been developed to improve patient outcomes beyond the current standard of care. These novel agents target pathways related to atherogenic lipoprotein clearance, renal glucose and potassium handling, endogenous incretins, and coagulation. In addition, emerging targets include anti-atherogenic lipoproteins, inflammatory cytokines, and dual and triple antithrombotic therapy. This review outlines important updates in cardiovascular pharmacotherapy and provides guidance on practical use in clinical practice and an outlook to emerging therapeutics.
Can creative reinterpretation keep operetta alive? Kálmán’s Die Herzogin von Chicago at the Vienna Volksoper in 2004
Authors: Feurzeig Lisa
Published: November 2017

Kálmán’s 1928 operetta Die Herzogin von Chicago reemerged in the 1990s after decades of oblivion. Productions of this work can reveal much about topics such as the relationship of Central Europe and America and attitudes toward outsider groups, both in the 1920s and in more recent times. This study of the 2004 production at the Vienna Volksoper uses interviews to explore the work’s political and social meanings for Austrian audiences. It also examines the changes made in this production, which was adapted from the original by Stefan Frey and Dominik Wilgenbus, examines the question of what is “true operetta style,” and considers recent operetta reception in Vienna, with attention to the very different responses of the audience and the critics.
Nádors Erzählungen oder das Budapester Dreimäderlhaus. Ein Beitrag zur Budapester Offenbach-Rezeption
Authors: Bozó Péter
Published: November 2017

Mihály Nádor’s and Jenő Faragó’s three-act operetta entitled Offenbach was one of the biggest theater successes in Budapest in the period following World War I. The piece, whose first performance took place at the Király Theater in 1920, was also premiered in Vienna, Prague, Munich and in different adaptations in Berlin and New York. It represents a popular type of operetta of the era, whose main protagonists are nineteenth-century composers, and whose music was partly or entirely compiled of melodies taken from the musicians in question. In my study, I examine the extant musical and textual sources of the piece partly belonging to the composer’s estate preserved at the Music Department of the Széchényi National Library. I interpret Nádor’s work as a document of the Budapest Offenbach reception, and I reveal some intriguing differences between the Budapest and Vienna versions of the piece. I also demonstrate that the operetta was in all likelihood an imitation of Henrich Berté’s similar piece, Das Dreimäderlhaus, which was performed in every Budapest operetta theater between 1916 and 1924. At the same time, however, a successful new production of Offenbach’s La Belle Hélène was likewise an important antecedent for Nádor’s operetta.
Goldmark’s wild Amazons drama and exoticism in the Penthesilea overture
Authors: Roper Jane
Published: November 2017

Goldmark was the first of several composers to write a work based on Heinrich von Kleist’s controversial play, Penthesilea. Early critical opinion about the overture was divided. Hanslick found it distasteful, whereas others were thrilled by Goldmark’s powerful treatment of the subject. Composed in 1879, during the 1880s Penthesilea became established in orchestral repertoire throughout Europe and America. The overture represents the conflict of violence and sexual attraction between the Queen of the Amazons and Achilles. Exoticism in the play is achieved by contrasting brutal violence, irrational behaviour and extreme sensual passion. This is recreated musically by drawing on topics established in opera. Of particular note is the use of dissonance and unexpected modulations, together with extreme rhythmic and dynamic contrast. A key feature of the music is the interplay between military rhythms representing violence and conflict, and a legato, rocking theme which suggests desire and sensuality.
Orientalismus als Kategorie des komischen Ambroise Thomas’ und Thomas Sauvages opéra-bouffon Le caïd
Authors: Zechner Ingeborg
Published: November 2017

After its premiere in 1849 Ambroise Thomas’ and Thomas Sauvage’s opéra-bouffon Le caïd remained extremely successful throughout Europe. This was caused mostly because of its parodistic references to the orient in plot, scenery, libretto and music. This article examines the orientalistic features of Le caïd, which contemporary music critics perceived as comical. The reception documents are also evaluated in the context of the perception of orientalism in the nineteenth century as well as in the tradition of opéra-comique. The categories considered in the work’s analysis are the comical dimension of the orient, the opposition between France and Algeria functioning as a comic element, as well as the parody of the orientalistic Italian opera buffa.
