Authors: Pech Maciej , Serafin Zbigniew , Fischbach Frank , Damm Robert , Jargiełło Tomasz , Seidensticker Max , Powerski Maciej 
Published: March 2020

Objective:
Iatrogenic hemorrhages occur in 0.5–16% of medical procedures. A retrospective study was conducted to analyze technical and clinical outcome of transarterial embolization (TAE) used for acute iatrogenic hemorrhage and to identify factors predicting outcome.

Methods:
All patients undergoing TAE for acute iatrogenic bleeding from 2006 to 2013 were retrospectively analyzed. Primary end points were technical and clinical success or failure and 30 day mortality.

Results:
A total of 153 patients underwent 182 TAEs. Factors associated with clinical failure were lower blood hemoglobin concentration, use of higher number of units of red blood cell concentrate, TAE performed at night or weekend, embolization of more than one vessel, shock state before digital subtraction angiography (DSA), and intensive care before TAE. In multivariate analysis, independent factors for clinical success were hemoglobin concentration, number of units of red blood cell concentrate, and TAE of more than one vessel. Technical failure was associated with female gender, failure to detect signs of bleeding in DSA, TAE of more than one vessel, and shock state before DSA. Bleeding related to anticoagulation medication resulted in a significantly higher mortality rate compared with bleeding due to the remaining causes (30% vs 15%, p &lt; 0.05).

Conclusion:
Despite excellent technical success, the mortality rate was significant. The only factors affecting clinical success were bleeding intensity and extent of injury. Bleeding attributed to anticoagulation is related to high mortality and therefore requires special attention.

Advances in knowledge:
This study gives insights into morbidity and mortality of iatrogenic bleedings and the technical and clinical success rates of TAE in a large study population.
Ultrasound elastography in characterization of prostatic lesions: correlation with histopathological findings
Authors: Emara Doaa M , Naguib Nagy N. , Yehia Mohamed , El Shafei Mohamed M. 
Published: March 2020

Objective:
Ultrasound elastography is increasingly used in the diagnosis of prostate cancer, however results are heterogeneous. We correlate in a large sample-size prospective study the accuracy of elastography, aiming to settle an accurate cut-off point for diagnosis and possibility of use as a screening tool.

Methods:
Prospective study that included 120 patients with mean age 59.5 ± 9.8 years, showing enlarged prostate by clinical examination with prostate-specific antigen &gt;4 ng ml−1.
The study was done using high frequency high resolution endorectal probe with real time tissue elastography.
Grayscale ultrasound examination was done first with Doppler followed by elastography color-coded map and strain ratio measurement. Then, transrectal ultrasound-guided core biopsy was done from suspicious areas detected by elastography (totally or partly stiff by color-coded map or with relative increased strain ratio), besides standard six-quadrant core biopsy samples.

Results:
There was statistically significant difference (p &lt; 0.001) regarding strain ratio in benign and malignant lesions. Strain ratio showed significant proportionate correlation with prostate-specific antigen level and Gleason pathological score, while no significant correlation noted with the age or the prostatic volume. A strain ratio with a cut-off value of 1.9 showed a sensitivity of 100%, specificity 93.8%, positive predictive value of 79.3%, negative predictive value 100 and 95% accuracy in differentiating between malignant and benign lesions.

Conclusion:
Strain ratio improves the detection of prostatic cancer with high sensitivity (100%) and high negative predictive value (100%).

Advances in knowledge:
Different prostatic lesions are mostly similar in grayscale ultrasound.
Imaging plays an important role in differentiation of prostatic nodules.
Ultrasound elastography may play an important role in distinguishing benign from malignant nodules.

Published: March 2020

INTRODUCTION:
There are only limited data on the survival outcomes after transplanting HCV RNA–positive liver into HCV RNA–negative recipients. The objective of our study was to determine whether there were graft and patient survival differences when HCV-negative patients received HCV RNA (nucleic acid amplification testing [NAT] positive)–positive liver grafts.

METHODS:
We queried the United Network for Organ Sharing data sets from January 2014 to December 2018, and recipients (N = 24,724) were stratified into 6 groups based on the status of HCV antibody and RNA of recipients and donors. The Cox proportional hazard regression was used to estimate the relationship between groups and 1-year post-LT graft or patient survival.

RESULTS:
During the study period, 1,358 recipients received NAT-positive liver grafts. Two hundred ten of the recipients were HCV negative. During the same period, 707 HCV antibody–positive but NAT-negative grafts were transplanted into 516 HCV-positive and 191 HCV-negative recipients. There were no differences in survival in HCV-positive recipients whether they received NAT-positive grafts (n = 1,148) or HCV antibody–negative/NAT-negative grafts (n = 6,321). Recipients of grafts from HCV antibody–positive/NAT-negative donors had similar survival whether recipients were HCV-negative patients (n = 191) or HCV-positive patients (n = 516), and their survival probabilities were similar to those of HCV-negative recipients (n = 6,321) receiving grafts from HCV antibody–negative/NAT-negative donors. Patient survival was lower (P = 0.049) when HCV-negative recipients (n = 210) received NAT-positive grafts compared with HCV-positive patients (n = 1,148) receiving NAT-positive grafts; however, when adjusted for recipient and donor characteristics, the difference was not significant.

DISCUSSION:
HCV-negative recipients receiving HCV-positive liver grafts (NAT positive) have excellent 1-year survival outcomes.
Consumers and the Sources of US Trade Openness
Authors: Betz Timm 
Published: March 2020

AbstractThis essay reviews US trade flows and trade policy from the perspective of consumers. Trade policy shapes the prices and the availability of products sold in the US to, ultimately, voters. Understanding the role of consumers in explaining US trade policy may therefore offer lessons for our understanding of politics beyond trade. International trade has created substantial gains for consumers, both by lowering domestic prices and by increasing access to a wider variety of products. Yet, US trade policy does not appear to reflect consumer interests: tariffs are higher for products with higher consumption shares. This finding is inconsistent with the narrative that open trade is a response to consumer interests, and it is not explained by standard collective action arguments either. Instead, the political influence of pro-trade firms emerges as a driving force of US trade openness. The essay discusses the implications for our understanding of the political and institutional sources of trade openness. If special interest politics explains the opening of trade, it reverses the traditional interpretation of trade openness as an indication of the absence of special interest politics.
Sedimentary succession and recognition marks of lacustrine gravel beach-bars, a case study from the Qinghai Lake, China
Authors: Peng Biao , Han Jichang , Xie Xiao , Wang Luyao 
Published: March 2020

Abstract
The present is the key to the past. Based on the dissection of modern beach-bars in the Qinghai Lake, Qinghai-Tibet Plateau, China, including two profiles parallelly to the shoreline, two profiles vertically to the shoreline and one plane-view profile, the sedimentary succession and recognition marks of lacustrine gravel beach-bars have been summarized. Vertically, the lacustrine gravel beach-bars develop with the “ABC” succession. The A interval, the B interval, and the C interval respectively correspond with the gravelly sand facies, the well-sorted gravel facies, and the graded sand facies. The lacustrine gravel beach-bars is composed of several combinations of the “ABC” succession, such as “ABAB”, “ABCABC”, “BCBC”. The main recognition marks of lacustrine gravel beach-bars is the following: the bottom contact is distinct and with the “ABC” succession; and the lacustrine beach-bars develop the swash bedding and sheet-like parallelly to the lakeshore. These viewpoints have significant contributions to the reconstruction of paleoenvironments and paleoshorelines and to the reservoir interpretation within lacustrine beach-bar clastic bodies.
Reevaluating the German labor market miracle
Authors: Burda Michael C. , Seele Stefanie 
Published: March 2020

AbstractFrom 2003 to 2018, employment in Germany increased by 7.3 million, or by 19.3 % – growth not observed since unification. This “labor market miracle” was marked by a persistent and significant expansion of both part-time and low-wage jobs and a deterioration in pay for these jobs, while total hours hardly increased; overall wage growth returned only after 2011. These developments followed in the wake of the landmark Hartz reforms (2003–2005). A modified framework of Katz and Murphy (1992) predicts negative correlation of wages with both relative employment and participation across cells in the period following these reforms. In contrast, wage moderation alone should generate positive association of wages and participation. Our findings are most consistent with a persistent, positive labor supply shock at given working-age population in a cleared labor market. An alternative perspective of labor markets, the search and matching model, also points to the Hartz IV reforms as the central driver of the German labor market miracle.
Numerical Solutions Based on a Collocation Method Combined with Euler Polynomials for Linear Fractional Differential Equations with Delay
Authors: Konuralp Ali , Öner Sercan 
Published: March 2020

Abstract
In this study, a method combined with both Euler polynomials and the collocation method is proposed for solving linear fractional differential equations with delay. The proposed method yields an approximate series solution expressed in the truncated series form in which terms are constituted of unknown coefficients that are to be determined according to Euler polynomials. The matrix method developed for the linear fractional differential equations is improved to the case of having delay terms. Furthermore, while putting the effect of conditions into the algebraic system written in the augmented form in which the coefficients of Euler polynomials are unknowns, the condition matrix scans the rows one by one. Thus, by using our program written in Mathematica there can be obtained more than one semi-analytic solutions that approach to exact solutions. Some numerical examples are given to demonstrate the efficiency of the proposed method.
La religion est-elle « purement une affaire de raison » ?
Authors: Theis Robert 
Published: March 2020

AbstractThis study reflects upon the fundamental justification of the radicality of Kant’s affirmation according to which religion is “a matter of reason alone”.To this end, this paper bores in two directions: In a first direction, the premises as well as the context of the Critique of Practical Reason’s thesis, according to which the moral law leads to religion, are reconstructed. The question that needs to be clarified in this context concerns the semantic content of the concept of religion that is introduced here in Kant’s argumentation. That question’s resolution will help to show the sense in which religion is not merely a matter of reason alone.In a second direction, further inquiries are made regarding Religion within the Limits of Reason Alone on the ‘plural relation’ between two discourses that originate in different sources – reason and revelation. This shows the sense in which revealed religion enriches reason’s discourse.In that respect, the complexity of the Kantian arguments does not allow us to maintain outright the thesis that religion is a matter of reason alone.
QTc interval predicts disturbed circadian blood pressure variation
Authors: Yan Liyuan , Jin Jianling , Jiang Shili , Zhu Wei , Gao Meiwen , Zhao Xin , Yuan Jiamin 
Published: March 2020

Abstract

Background
The relationship between electrocardiographic evaluation and circadian blood pressure (BP) variation in young and middle-aged hypertensive patients remains unknown.

Methods
A total of 171 hypertensive patients were included in the study. First, patients were divided into a young and middle-aged group and an elderly group. The two groups were then separately classified into three subgroups on the basis of circadian variation of BP as dippers, non-dippers and reverse-dippers. The electrocardiographic evaluation was calculated from 12-lead electrocardiography (ECG).

Results
QTc intervals were shortest in the dippers and longest in the reverse-dippers in the young and middle-aged group (QTc dipper: 416.53±18.37ms; non-dipper: 438.30±29.71ms; reverse-dipper: 444.93±25.47ms; for dipper vs non-dipper, and dipper vs reverse-dipper P<0.05). QTc interval was found to be an independent risk factor for the non-dipper BP pattern (Odds ratio 1.049; 95% CI 1.01-1.089; P=0.012) and reverse-dipper BP pattern (Odds ratio 1.051; 95% CI 1.007-1.098; P=0.023) in young and middle-aged hypertensive patients. No significant differences in other ECG parameters were found among the three subgroups in the young and middle-aged group.

Conclusion
Our study suggested that QTc interval might serve as a risk factor for non-dipper BP pattern and reverse-dipper BP pattern in young and middle-aged hypertensive patients.
Dominant species drive seasonal dynamics of the fish community in the Min estuary, China
Authors: Li Jun , Kang Bin 
Published: March 2020

Abstract
Fishery resources are currently facing multiple stresses such as overfishing, pollution and climate change. Looking into processes and mechanisms of the dynamic fish community through detailed quantitative analyses contributes to effective conservation and management of fishery resources. The Min estuary plays an important role in maintaining fisheries in southeastern coastal China, therefore the fish community in the brackish area was investigated and analyzed in this study. A total of 127 species belonging to 91 genera, 49 families and 14 orders were sampled in 2015. Eight indices reflecting four aspects of fish communities were determined, i.e. species richness, species evenness, heterogeneity and taxonomy. Differences between the indices were nonsignificant, suggesting that the use of a single diversity descriptor could not provide a full explanation. Nine dominant species in the Min estuary showed seasonal turnover by rational use of resources and co-occurring species showed correspondingly adequate habitat preferences and feeding habits to avoid competition. The species Harpadon nehereus occurred as the dominant species in three seasons except spring. High values of niche overlap among common or rare species and lower values of niche overlap among all dominant species effectively brought the diversity of the fish community into a state of equilibrium.
The use of 18S ribosomal DNA, ITS and rbcL molecular markers to study the genus Dunaliella (Dunaliellaceae) in Iranian samples: A phylogenetic approach
Authors: Dehghani Jaber , Atazadeh Ehsan , Omidi Yadollah , Movafeghi Ali 
Published: March 2020

Abstract
The microalga Dunaliella has been the focus of attention over recent decades owing to its high biotechnological potential for the production of β-carotene, biofuels and even as a good expression system for the production of recombinant proteins. Different species of this genus have unique features, biological characteristics and biotechnological potential. Therefore, it is necessary to have a clear and reliable taxonomic method to identify different species of Dunaliella. Although several taxonomic systems are available for Dunaliella based on morphological, physiological and molecular features, none of these methods are reliable enough and some controversies exist over different classification systems. In the current study, molecular techniques and bioinformatics tools have been used to re-assess the phylogenetic position of Dunaliella species based on 18S ribosomal DNA (18S rDNA), ITS and rbcL regions. The overall findings based on these markers provide a new and more reliable tool for phylogenetic analysis of Dunaliella species/strains.
A General Viscous Model for Some Aspects of Tropical Cyclonic Winds
Authors: Pandey Sanjay Kumar , Maurya Jagdish Prasad 
Published: March 2020

Abstract
A previous investigation found that the existence of double exponential terms is a reason for rapid intensification of cyclonic winds with the assumption of a linearised form of viscosity. Here, we consider viscosity of general type and still get similar terms. A perturbation technique is applied to the solution. The domain of analysis is split into two regions: an inner one that experiences updraft, and an outer one that possesses no vertical component of velocity but does have azimuthal and radial components. It is observed that the radial pressure difference between an arbitrary radial distance and the point of the maximum wind diminishes with height, time, and Reynolds number. The azimuthal velocity, close to the ground, in region 1 increases fast with time, but its dependence diminishes at a height a little above the ground. At a considerable height, time ceases to be a factor, and further, above that, trends reverse. Perturbation terms behave almost identically with the terms without perturbation. The significance of their contribution depends on the magnitude of the Reynolds number and, hence, the viscosity. Trends for region 2 are qualitatively similar to those in region 1 but differ quantitatively. It is also observed that the central pressure drop decreases with time.
Actual Problems of the Sports News Programs on TV
Authors: Makarova Polina 
Published: March 2020

In the last decades, sports journalism has become one of the most rapidly growing parts of the media world. The reason is simple — right now sport holds the unique position in contemporary society. Governments, transnational companies, businesses — all are interested in promoting sports events. With this, coverage of tournaments and games has reached the global level. One of the main drivers of this hype is the mutual interest in hundreds of dozens of sports events that is shared all over the world. And the second driver is vast technical possibilities for transmitting information in all forms.
Nowadays, new channels of mass communication are taking away significant part of the audience from the traditional sports broadcasting leader — television. News programs that once were a main source of the relevant sports information now are giving way to internet portals and digital media feeds. In this paper we thoroughly explore factors that have led to such drastic changes.
Firstly, compared with the new media sources of information (e.g. Internet media) the core flaws of the television news are the following: loss of efficiency, delayed timing, an abundance of themes, format limits, expensive newsroom, high competition, almost zero feedback. Yet, experts in the sports news departments are relentlessly seeking for a new way to represent information. What sports news can give to the audience? It may be some unique content, original insights, “story behind story”, deep analysis, and, of course, high professional qualities of the sports news team.
Digital World of Networked Teens and Their Visual Practices
Authors: Ershov Yuri 
Published: March 2020

The article presents the results of a pilot study of teen media practices. The study was conducted using focused interviews (with video recording) with 11 graders in three Siberian cities in March — April 2018. The survey project shows how the viewing is transformed as a sociocultural practice and why the YouTube videohosting fundamentally influences this process. The problem is connected with generational (digital) gap and non-fulfillment of the natural loss of the audience of television channels by young viewers. Not only university departments and academic centers, but also the research services of consulting companies and corporations are studying this media consumerism problem today, since the request for such research is formulated throughout the media industry. An analysis of the data from a focused interview shows that the media activity of school students is not fully comprehended by them: adolescents cannot yet appreciate time and control it. Television viewing has become largely ritual in nature and serves to strengthen emotional ties with the family. Without personal involvement in the media process, adolescents' interest in watching or reading is quickly fading. For teens, the privacy of their lives in social networks and the ability to comment on any web content is of great importance. The author assumes in a discussion key the possibilities of integrating social media and television, justifying the forecast for the development of this sector of the media market. Patterns of adolescent media activity will undoubtedly influence in the future the behavior of adults in the media environment. This research project was undertaken to respond to an industrial query: how management should change media platforms and content policies to captivate the younger generation and win their loyalty.
