Background:
Pain catastrophizing has been identified as a prognostic indicator of poor outcome following knee arthroplasty. Interventions to address pain catastrophizing, to our knowledge, have not been tested in patients undergoing knee arthroplasty. The purpose of this study was to determine whether pain coping skills training in persons with moderate to high pain catastrophizing undergoing knee arthroplasty improves outcomes 12 months postoperatively compared with usual care or arthritis education.

Methods:
A multicenter, 3-arm, single-blinded, randomized comparative effectiveness trial was performed involving 5 university-based medical centers in the United States. There were 402 randomized participants. The primary outcome was the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) Pain Scale, measured at baseline, 2 months, 6 months, and 12 months following the surgical procedure.

Results:
Participants were recruited from January 2013 to June 2016. In 402 participants, 66% were women and the mean age of the participants (and standard deviation) was 63.2 ± 8.0 years. Three hundred and forty-six participants (90% of those who underwent a surgical procedure) completed a 12-month follow-up. All 3 treatment groups had large improvements in 12-month WOMAC pain scores with no significant differences (p > 0.05) among the 3 treatment arms. No differences were found between WOMAC pain scores at 12 months for the pain coping skills and arthritis education groups (adjusted mean difference, 0.3 [95% confidence interval (CI), −0.9 to 1.5]) or between the pain coping and usual-care groups (adjusted mean difference, 0.4 [95% CI, −0.7 to 1.5]). Secondary outcomes also showed no significant differences (p > 0.05) among the 3 groups.

Conclusions:
Among adults with pain catastrophizing undergoing knee arthroplasty, cognitive behaviorally based pain coping skills training did not confer pain or functional benefit beyond the large improvements achieved with usual surgical and postoperative care. Future research should develop interventions for the approximately 20% of patients undergoing knee arthroplasty who experience persistent function-limiting pain.

Assessing the Benefit of Polymer‐Coated Urea for Corn Production on Irrigated Sandy Soils
Authors: Rui Yichao , Ruark Matthew D. , Andraski Todd W. , Bundy Larry G. 
Published: February 2019

Core Ideas

Polymer‐coated urea led to greater yields compared to other N fertilizers when all applied preplant.
The performance of preplant polymer‐coated urea is reduced in high rainfall years.
Split application of ammonium sulfate consistently produced the greatest yields on irrigated sands.
Nitrification inhibitor showed little impact on corn yield on irrigated sandy soils.
Polymer‐coated urea (PCU) is an enhanced‐efficiency fertilizer product that can potentially increase N use efficiency, thereby reducing N losses to the environment. However, the optimum timing and rates of PCU application under varying seasonal precipitation is less known. Here we studied the response of corn (Zea mays L.) yield and N use efficiency to N timing (preplant, sidedress, and split application) and rates (112–280 kg N ha−1) of PCU, ammonium sulfate (AS), and urea, including a control treatment without N, on an irrigated sandy soil (90% sand) in central Wisconsin from 2003 to 2006. The effect of N rate on grain yield was significant in 2003, 2004, and 2005, but not in 2006. Grain yield and N recovery efficiency (RE) with preplant PCU was greater in 2004 and 2005, and similar in 2003 and 2006 compared with preplant AS or urea. Preplant PCU had similar or greater yield and RE compared with split‐applied AS in 3 yr, but lower yield and RE in the year with the greatest early season rainfall. Nitrification inhibitor (dicyandiamide) showed little impact on corn yield. These results indicated that PCU, when applied preplant, was agronomically and environmentally advantageous over the other N fertilizer sources and typically performed as well as split application of other N fertilizers. However, under conditions where there is a lot of early season rainfall, use of preplant PCU would still result in N losses and then crops would need supplemental N to achieve high yields.
Break Up Variations: An Annotated Score
Authors: Constraints Generative 
Published: February 2019

Break Up Variations is an annotated score by means of which we consider the document as a break-up from — and with — the thinking of performance. We explore the formal categories of page-based and stage-based scores and documentations of performance, asserting the simultaneity of the document and its performance in their mutual departures, theorising the break-up as a form of relation, not as its absence. As a committee of interdisciplinary researchers and practitioners, we consider annotation in terms of affective and theoretical responses to each other’s subject positions.Break Up Variations relates to the problems particular to working in groups: the challenges of collaboration, the disagreements and community-led conflict resolutions, the difficulties with acting professionally, and the desires to keep working together, despite it all. We ask the following questions of each other and ourselves: What are the strategies that art, science, politics and theory might offer each other for navigating — possibly circumventing — the demise of relationships? If the working relationship breaks down, could the end of the group be considered a constitutive aspect of that group? We consider these questions to be about institutions as much as they are about interdependence on personal and planetary scales. Riffing on ideas about romantic break-ups, political dissolutions and ecological collapse, Break Up Variations considers the possibility that an end to a dream of symbiotic life is exactly what makes that dream possible and important.

Exploring the multiscale changeability of precipitation using the entropy concept and self-organizing maps
Authors: Roushangar Kiyoumars , Alizadeh Farhad , Adamowski Jan , Saghebian Seyed Mehdi 
Published: February 2019

AbstractThis study utilized a spatio-temporal framework to assess the dispersion and uncertainty of precipitation in Iran. Thirty-one rain gauges with data from 1960 to 2010 were selected in order to apply the entropy concept and study spatio-temporal variability of precipitation. The variability of monthly, seasonal and annual precipitation series was studied using the marginal disorder index (MDI). To investigate the intra-annual and decadal distribution of monthly and annual precipitation values, the apportionment disorder index (ADI) and decadal ADI (DADI) were applied to the time series. The continuous wavelet transform was used to decompose the ADI time series into time-frequency domains. The decomposition of the ADI series into different zones helped to identify the dominant modes of variability and the variation of those modes over time. The results revealed the high disorderliness in the amount of precipitation for different temporal scales based on disorder indices. Based on the DI outcome for all rain gauges, a self-organizing map (SOM) was trained to find the optimum number of clusters (seven) of rain gauges. It was observed from the clustering that there was hydrologic similarity in the clusters apart from the geographic neighborhood.

La evolución de las brechas digitales y el auge de la Inteligencia Artificial (IA)
Authors: Lombana Bermudez Andrés 
Published: February 2019

Las promesas de acceso a la información, democratización del conocimiento, desarrollo económico y mayor participación, han sido un potente motor para la difusión de las Tecnologías de Información y Comunicación (TIC) en la mayoría de países del mundo. Sin embargo, luego de varias décadas de esfuerzos por cerrar la "brecha digital" y con más de medio planeta conectado a Internet, los augurios de la transformación en este ámbito continúan sin realizarse por completo. Las desigualdades socioeconómicas y culturales han determinado la manera en que diferentes individuos y grupos han apropiado las herramientas y redes digitales y han accedido a oportunidades. En vez de una sola brecha digital de carácter tecnológico, científicos sociales han demostrado que existen múltiples fracturas estructurales que dan forma a los procesos de apropiación de tecnologías. El rápido desarrollo de TIC de última generación, como el caso de los sistemas de Inteligencia Artificial (IA) y su despliegue a través de varias dimensiones sociales, probablemente profundizará las desigualdades digitales existentes. Hoy en día, la IA ya está siendo aplicada alrededor del mundo en diferentes sectores como: las finanzas, la educación y la distribución de noticias en redes sociales. Para comprender el impacto que la IA tendrá en la sociedad, economía, política y cultura y, asimismo, ayudar a que su difusión se lleve a cabo de una manera más justa, ética y humana, es necesario reconocer la existencia de múltiples brechas digitales que van más allá del simple acceso a tecnología. Este artículo explora la evolución de las desigualdades digitales con una perspectiva histórica y crítica que permite comprender sus matices y complejidad, evitar el determinismo tecnológico y situar el auge de la IA como parte de un proceso acelerado de transformación digital a escala nacional, regional y global.

Published: February 2019

Aims
Transcatheter aortic valve implantation has become an established treatment for severe aortic stenosis, thanks to key improvements achieved by new-generation devices. Their comparative effectiveness and safety are, however, still uncertain.

Methods
We queried a prospective registry on transcatheter aortic valve implantation to compare Evolut and Portico devices, focusing on procedural, in-hospital, and mid-term outcomes. Unadjusted and propensity-adjusted analyses were carried out.

Results
In all, 233 patients were included, 119 (51.1%) receiving Evolut and 114 (48.9%) Portico. Several differences in baseline and procedural features were evident, including comorbidities, device size, and postdilation (all P < 0.05). Unadjusted analysis for procedural results showed significant differences in fluoroscopy time, left ventricular ejection fraction, and aortic regurgitation (all P < 0.05), whereas device and procedural success rates were not significantly different (both P > 0.05). In-hospital outcomes were not significantly different (all P > 0.05). Survival analysis for mid-term follow-up (6 ± 7 months) outcomes showed no significant differences in death, stroke, myocardial infarction, major vascular complication, or major bleeding (all P > 0.05). Conversely, Evolut appeared associated with lower peak and mean aortic gradients (both P < 0.05), but higher rate of permanent pacemaker implantation (P = 0.043). Propensity-score-adjusted analysis largely confirmed the similar performance of the two devices, including peak and mean aortic gradients (both P > 0.05). However, Evolut continued to be associated even at adjusted analysis with an increased risk of pacemaker implantation (P = 0.018).

Conclusion
The acute and mid-term comparative safety and effectiveness of Evolut and Portico in experienced hands are similar, with the notable exception of a lower risk of permanent pacemaker implantation with Portico.

Authors: Flocco Serena Francesca , Dellafiore Federica , Caruso Rosario , Giamberti Alessandro , Micheletti Angelo , Negura Diana Gabriela , Piazza Luciane , Carminati Mario , Chessa Massimo 
Published: February 2019

Aims
The aim of this study was to assess the impact of a transition clinic model on adolescent congenital heart disease (CHD) patients’ health perception outcomes. The transition clinic model consists of multidisciplinary standardized interventions to educate and support CHD patients and represents a key element in the adequate delivery of care to these individuals during their transition from childhood to adulthood. Currently, empirical data regarding the impact of transition clinic models on the improvement of health perceptions in CHD adolescent patients are lacking.

Methods
A quasi-experimental design was employed. Quality of life, satisfaction, health perceptions and knowledge were assessed at the time of enrolment (T0) and a year after enrolment (T1), respectively. During the follow-up period, the patients enrolled (aged 11–18 years) were involved in the CHD-specific transition clinic model (CHD-TC).

Results
A sample of 224 CHD adolescents was enrolled (60.7% boys; mean age: 14.84 ± 1.78 years). According to Warnes’ classification, 22% of patients had simple heart defect, 56% showed moderate complexity and 22% demonstrated severe complexity. The overall results suggested a good impact of the CHD-TC on adolescents’ outcomes, detailing in T1 the occurrence of a reduction of pain (P < 0.001) and anxiety (P < 0.001) and an improvement of knowledge (P < 0.001), life satisfaction (P < 0.001), perception of health status (P < 0.001) and quality of life (P < 0.001).

Conclusion
The CHD-TC seems to provide high-quality care to the patient by way of a multidisciplinary team. The results of the present study are encouraging and confirm the need to create multidisciplinary standardized interventions in order to educate and support the delivery of care for CHD adolescents and their families.

Published: February 2019

Aims
QT interval may be considered an indirect marker of atrial repolarization. Aim of our study was to verify if QT interval variations precede the onset of atrial fibrillation (AF).

Methods
We analyzed 21 AF onsets recorded at 24-h Holter ECG. Triggering supraventricular extrabeats (TSVEB) were identified and matched to nontriggering supraventricular extrabeats (NTSVEB) with the same prematurity index. QT and QTc intervals and their variability (max–min QT interval) were measured in the 10 beats preceding TSVEB and NTSVEB.

Results
QTc (470.1 ± 56.7 vs. 436.7 ± 25.6 ms; P = 0.006), QT (36.8 ± 13.1 vs. 21.1 ± 10.1 ms; P = 0.001) and QTc variability (41.5 ± 15.8 vs. 23.1 ± 11.9; P = 0.001) significantly varied between TSVEB and NTSVEB. By stratifying AF onsets in vagal (n = 10) and adrenergic (n = 11) according to Heart Rate Variability, significant differences emerged concerning QT (35.20 ± 16.48 vs. 22.70 ± 10.23 ms, P = 0.006) and QTc variability (39.30 ± 18.32 vs. 25.60 ± 12.91 ms, P = 0.029) for vagal onsets and QTc (477.73 ± 57.50 vs. 438.00 ± 28.55 ms, P = 0.045), QT (38.36 ± 9.79 vs. 19.73 ± 10.21 ms, P = 0.005) and QTc variability (43.55 ± 13.72 vs. 20.82 ± 11.01 ms, P = 0.004) for adrenergic onsets. By stratifying AF onsets in type I (n = 7) or II (n = 14) according to a cycle length variation in the 30 s before the onset greater or smaller than 10% respectively, significant differences were noted concerning QTc (477.73 ± 57.50 vs. 438 ± 28.55 ms, P = 0.045), QT (43.55 ± 13.72 vs. 20.82 ± 11.01 ms, P = 0.005) and QTc variability (43.55 ± 13.72 vs. 20.82 ± 11.01 ms, P = 0.004) in type I and QT (35.20 ± 16.48 vs. 22.70 ± 10.23 ms, P = 0.006) and QTc variability (39.30 ± 18.32 vs. 25.60 ± 12.91 ms, P = 0.029) in type II onsets.

Conclusion
Prolongation and QT variability represent a relevant substrate marker in the genesis of AF, independently of the trigger type.

Urban Gardening as a Multifunctional Tool to Increase Social Sustainability in the City
Authors: Koroļova Alisa , Treija Sandra 
Published: February 2019

Abstract
The concept of urban gardening varies a lot in terms of gardening forms and main purposes. Followed by changes in people life style, growing interest in healthy living and sustainable urban development, the aims of urban gardening become more complex. The product of urban garden, e. g. vegetables or ornamental plants, nowadays plays less important role, as the main focus is on societal issues, urban regeneration, education and health. Thus, this article provides evidence of multi-functionality of urban gardening to address the variety of societal issues across people of different age and cultural background. Case studies from Malmo, Birmingham and Riga show how urban gardening contributes to social integration, inhabitants’ well-being and urban regeneration.
The Logic of Constructivism
Authors: Díez Gustavo Fernández 
Published: February 2019

Abstract
In this paper I dispute the current view that intuitionistic logic is the common basis for the three main trends of constructivism in the philosophy of mathematics: intuitionism, Russian constructivism and Bishop’s constructivism. The point is that the so-called ‘Markov’s principle’, which is accepted by Russian constructivists and rejected by the other two, is expressible in intuitionistic first-order logic, and so it appears to have the status of a logical principle. The result of appending this principle to a complete intuitionistic axiom system for first-order predicate logic constitutes a new logic, which could well be called ‘Markov’s logic’, and which should be regarded as the true logical system underlying Russian constructivism.
Estonia’s comprehensive approach to national defence: origins and dilemmas
Authors: Veebel Viljar , Ploom Illimar 
Published: February 2019

AbstractThis study aimed to offer an in-depth insight into intellectual dilemmas associated with a comprehensive approach to national defence using Estonia as an example to demonstrate that comprehensive approach in itself may not be enough to feel safe and secure. The authors focused on two specific theoretical questions. First, how security threats are determined in Estonia, including the impact of such a phenomenon as macro-securitization? Second, how various levels of comprehensive approach relate to each other in the way that a shared security culture will be created? In this way, the aim of this article was not only to shake the foundations of national defence in Estonia but also to contribute to the improvement of the current model to ensure that it actually works in practice.
Political Trust and Russian Media in Latvia
Authors: Berzina Ieva 
Published: February 2019

Abstract
Russia’s attempts to influence public opinion outside its borders attracted increased interest in the context of its involvement in the war in Ukraine, Brexit referendum, the elections in the US and other political processes in the West. This article focuses on the assumption that Russian activities in the information environment of NATO and the EU member states among other things are aimed at undermining public trust in democratic governance institutions. Russian state-owned media is one of the tools about how Kremlin disseminates and promotes its worldview within and outside Russia’s borders; therefore, the research questions being addressed in this paper are related to the relationship between political trust and consumption of Russian media. To study this issue, Latvia was chosen as an outstanding case due to the relatively large presence of Russian media content in its information environment. The paper examines the trends of Russian media consumption and political trust in Latvia to assess if this is a fruitful further research area since linking political trust and Russia’s information activities is a new perspective on the issue. The theoretical part of the paper outlines the concept of political trust and the factors affecting it as they are identified in previous research, with a specific focus on the impact of media on political trust. The empirical part of the paper examines the trends in the growth of the audience of the TV channels retranslating Russian media content and political trust in Latvia in the period from 2007 to 2017. Considering that political trust in Latvia is increasing alongside with an increase in Russian media consumption, this paper suggests several further research directions with a focus on political and economic performance indicators and the impact of domestic media.
