Big Five Personality Model-based study of death coping self-efficacy in clinical nurses: A cross-sectional survey
Authors: Lin Xi , Li Xiaoqing , Liu Qing , Shao Shengwen , Xiang Weilan 
Published: May 2021

BackgroundSpecific personality traits may affect the ability of nurses to deal with patient death. The relationship between personality and death coping self-efficacy (DCS) has rarely been investigated in the palliative care setting. In this study, we explored the associations between different personality profiles and DCS in clinical nurses from general wards and ICU.MethodsA cross-sectional survey of 572 Chinese nurses was conducted between August and September 2020, by way of a self-administered questionnaire.ResultsAmong the Big Five Personality Traits, in nurses the score was highest for conscientiousness and lowest for neuroticism. With regard to DCS, nurses scored highly on the intention of hospice care. The Big Five Personality Traits were found to explain 20.2% of the overall variation in DCS. Openness, agreeableness and conscientiousness were significantly associated with DCS in nurses.ConclusionsNursing managers should pay attention to differences in personality characteristics and provide personalized and targeted nursing education. This should improve nurses’ DCS, enrich their professional development and promote high quality palliative care for patients and their families.
Professional written voice “in flux”: the case of social work
Authors: Lillis Theresa 
Published: May 2021

Abstract
Contemporary professional social work can be characterised by increased textualisation (after Iedema and Scheeres 2003) with written texts mediating most action. At the same time, writing, as a key dimension to social workers’ practice and labour, is often institutionally unacknowledged, becoming visible primarily when identified as a “problem.” This paper draws on a three year nationally funded UK-based research project to offer a situated account of contemporary professional social work writing, challenging dominant institutional orientations to writing in professional practice. The paper outlines the specific ways in which social work practices, including writing, can be characterised as being ‘in flux’. Drawing on ethnographic data and adopting a Bakhtinian (1981, 1986) oriented approach to voice, the paper explores the entextualisation of three specific social work texts, focusing in particular on critical moments (after Candlin 1987, 1997). These critical moments offer insights into key problematics of social work writing, in particular the tensions around professional voice and discourse. The paper concludes by arguing for an articulation of professional social work writing which takes account of the dialogic nature of language and the discoursal challenges experienced in everyday practice.
What About Realism? Alberto Blest Gana, Georg Lukács, and Their Chilean Readers
Authors: Patruno Luigi 
Published: May 2021

Abstract
In this article, I analyse Georg Lukács’s theories of realism in relation to Alberto Blest Gana’s work. For this purpose, I explore two essays that have greatly contributed to locating the Chilean author’s novels within the realm of literary realism. The texts chosen for my study are Jaime Concha’s prologue to the Martín Rivas edition by the Ayacucho Library and Ricardo A. Latcham’s essay “Blest Gana y la novela realista” [Blest Gana and the Realist Novel]. Concha and Latcham find appropriate categories for the interpretation of Blest Gana’s work in Lukács’s essays. In their readings, they accurately apply notions such as the selective principle or the typology of characters. However, while using those insights as a shared critical platform, they arrive at different interpretations of what is meant by realism. The article elucidates the role played by Concha and Latcham in the Chilean intellectual field and shows how literary genealogies inform their critical projects.
Basic Issues of Cultural Interaction: A European Perspective
Authors: Rüsen Jörn 
Published: May 2021

Abstract
The paper concentrates on the issue of ethnocentrism in cultural interaction. It briefly mentions the East Asian case and mainly tackles the European one. It gives examples of ethnocentric attitudes in history, but its main point is presenting examples of overcoming the unbalanced evaluation in expressing cultural identity and difference by means of new forms of generating a sense of history. Examples are discussed as indicators of new approaches to dealing with morality beyond the highly problematic distinction between good and evil along the line of self and other.

The inhibitory effect of conditioned pain modulation on temporal summation in low-back pain patients
Authors: O’Neill Søren , Holm Liam , Filtenborg Johanne Brinch , Arendt-Nielsen Lars , Nim Casper Glissmann 
Published: May 2021

Abstract

Objectives
The literature on conditioned pain modulation (CPM) is inconclusive in relation to low-back pain and it is unclear how CPM affects temporal summation as a proxy of central pain integration. The aim of this study was to examine whether the CPM effect would be different on pain induced by temporal summation than single stimuli in a group of low back pain patients.

Methods
A total of 149 low-back pain patients were included. CPM was examined using single, repeated and temporal summation (repeated-single difference) of mechanical pressure pain as test stimuli at an individualized, fixed supra-pain-threshold force, before and after 2 min of cold pressor test (0–2 degrees Celsius). Participants were categorized as CPM responders or non-responders according to three different criteria: simple (any pain inhibition), strict (pain inhibition of more than 10VAS) and reversed (pain inhibition or facilitation of less than 10VAS). Clinical data on back pain was collected for correlation and descriptive purposes.

Results
Significant modulation was observed for all three test stimuli. Effects sizes were comparable in relative terms, but repeated pressure pain modulation was greater in absolute terms. No correlations to clinical data were observed, for any measure.

Conclusions
The current data suggests that repeated pressure pain may be better suited as the CPM test stimuli, than single pressure pain and temporal summation of pressure pain, as the CPM effect in absolute terms was greater. Employing temporal summation as the test stimulus in a CPM paradigm may be more sensitive than a single test stimulus.
Immunoregulation and antidepressant effect of ketamine
Authors: Zhang Nan , Yao Lihua , Wang Peilin , Liu Zhongchun 
Published: May 2021

Abstract
Major depressive disorder (MDD) is a common mental health disorder that brings severe disease burden worldwide. Traditional antidepressants are mainly targeted at monoamine neurotransmitters, with low remission rates and high recurrence rates. Ketamine is a noncompetitive glutamate N-methyl-d-aspartate receptor (NMDAR) antagonist, and its rapid and powerful antidepressant effects have come to light. Its antidepressant mechanism is still unclarified. Research found that ketamine had not only antagonistic effect on NMDAR but also strong immunomodulatory effect, both of which were closely related to the pathophysiology of MDD. Although there are many related studies, they are relatively heterogeneous. Therefore, this review mainly describes the immune mechanisms involved in MDD and how ketamine plays an antidepressant role by regulating peripheral and central immune system, including peripheral inflammatory cytokines, central microglia, and astrocytes. This review summarizes the related research, finds out the deficiencies of current research, and provides ideas for future research and the development of novel antidepressants.
Ultrahang-elasztográfia alkalmazásának lehetőségei a szülészet-nőgyógyászatban
Authors: Kozma Bence , Pákozdy Krisztina , Lampé Rudolf , Berényi Ervin , Takács Péter 
Published: May 2021

Összefoglaló. Az ultrahang-elasztográfia az elmúlt évek során egyre
növekvő figyelmet kapott a lágyszövetek elaszticitásának vizsgálatában. A
módszer használatát az teszi szükségessé, hogy egyes, a mechanikai
tulajdonságaikban különböző szövetek hasonló echogenitásúak lehetnek, valamint
hogy egy adott szövet megváltozott struktúrája vagy mechanikai tulajdonsága nem
minden esetben jár együtt a szövet hagyományos ultrahangképének megváltozásával.
Az elmúlt évtizedben a deformációs és a nyírási ultrahang-elasztográfia vált
széles körben elérhetővé. Ezen új képalkotási technika egyre nagyobb szerepet
tölt be a szülészeti-nőgyógyászati ultrahang-diagnosztikában is. A
nőgyógyászatban szerephez juthat az endometriosis és az adenomyosis
kimutatásában, valamint a benignus és a malignus cervicalis és ovarialis
képletek elkülönítésében. A nőgyógyászathoz hasonlóan a szülészetben is jelentős
változást hozhat az ultrahang-elasztográfia: alkalmas lehet a szülésindukció
sikerességének, a koraszülés bekövetkezésének és a praeeclampsia kialakulásának
előrejelzésére. Orv Hetil. 2021; 162(18): 690–695.
Summary. Ultrasound elastography has received significant attention
for the assessment and measurement of soft tissue elastic properties in recent
years. The advantage of ultrasound elastography lies in the fact that two
different tissues can share similar echogenicities but may have other mechanical
properties or, on the contrary, mechanical abnormalities of a designated tissue
do not necessarily go hand in hand with an altered appearance on a conventional
ultrasound image. In the last decade, strain and shear-wave elasticity imaging
methods have become the most widely available among commercial ultrasound
equipments. The importance of this new method expands rapidly also in the field
of obstetrics and gynecology. Ultrasound elastography has a promising role in
the diagnosis of endometriosis and adenomyosis and helps to differentiate benign
and malignant cervical and ovarian lesions. The use in the prediction of the
outcome of labor induction and preterm birth, and in the evaluation of
preeclampsia are emerging. Orv Hetil. 2021; 162(18): 690–695.
Sex-Dependent Effects of Nephron Ift88 Disruption on BP, Renal Function, and Cystogenesis
Authors: Hu Chunyan , Lakshmipathi Jayalakshmi , Binning Elizabeth , Hyndman Kelly A. , Stuart Deborah , Kohan Donald E. 
Published: May 2021

Significance Statement
Primary cilia regulation of renal function and BP is incompletely understood. Mice with inducible nephron-specific Ift88 (a key ciliary protein) knockout (KO) were developed. Two months post-KO, males had reduced BP, increased natriuresis, and increased renal nitric oxide (NO) production; female KO mice had no phenotype unique from control mice. Nine months post-KO, males had cystic kidneys, hypertension, and reduced urinary NO excretion; female Ift88 KO mice had reduced BP and rare cysts. These findings indicate that nephron cilia disruption causes (1) strongly sex-dependent cystogenesis, (2) sex-dependent early BP reduction associated with eventual cyst formation, and (3) altered renal NO production.

Background
Primary cilia regulation of renal function and BP in health and disease is incompletely understood. This study investigated the effect of nephron ciliary loss on renal physiology, BP, and ensuing cystogenesis.

Methods
Mice underwent doxycycline (DOX)-inducible nephron-specific knockout (KO) of the Ift88 gene at 2 months of age using a Cre-LoxP strategy. BP, kidney function, and renal pathology were studied 2 and 9 months after DOX (Ift88 KO) or vehicle (control).

Results
At 2 months post-DOX, male, but not female, Ift88 KO, compared with sex-matched control, mice had reduced BP, enhanced salt-induced natriuresis, increased urinary nitrite and nitrate (NOx) excretion, and increased kidney NOS3 levels, which localized to the outer medulla; the reductions in BP in male mice were prevented by L-NAME. At 9 months post-DOX, male, but not female, Ift88 KO mice had polycystic kidneys, elevated BP, and reduced urinary NOx excretion. No differences were observed in plasma renin concentration, plasma aldosterone, urine vasopressin, or urine PGE2 between Ift88 KO and control mice at 2 or 9 months post-DOX.

Conclusions
Nephron cilia disruption in male, but not female, mice (1) reduces BP prior to cyst formation, (2) increases NOx production that may account for the lower BP prior to cyst formation, and (3) induces polycystic kidneys that are associated with hypertension and reduced renal NO production.

Quantitative Multiparameter Prediction of Fractured Tight Sandstone Reservoirs: A Case Study of the Yanchang Formation of the Ordos Basin, Central China
Authors: Liu Jingshou , Ding Wenlong , Yang Haimeng , Liu Yang 
Published: May 2021

Summary
Fractured reservoirs account for more than one-half of the global oil and gas output and thus play a pivotal role in the world’s energy structure. Under diagenesis, rocks become dense, and tectonic fractures easily form under subsequent tectonic movement. These tectonic fractures are the main seepage conduits of tight sandstone reservoirs and are important determinants of whether a tight sandstone reservoir can have high, stable oil and gas production. The influence of multistage tectonic movement has led to well-developed fractures in the Ordos Basin in central China. In the process of reservoir development, the effective stress on the fracture surface increases because of the decrease in pore pressure, and the fracture aperture, porosity, and permeability also change accordingly. Therefore, modeling of the dual porosity and dual permeability of fractured reservoirs requires a dynamic 4D modeling process related to time. In this paper, we propose a 4D modeling method of dual porosity and dual permeability in fractured tight sandstone reservoirs. First, the porosity and permeability distribution of the reservoir matrix are established based on reservoir modeling. Based on geomechanical modeling, the density and occurrence of natural fractures are predicted by the paleostress field. The in-situ stress field is used to analyze the fracture aperture, and the variation in the fracture aperture during the development process is analyzed along with the variation in the in-situ stress in the development process to realize 4D modeling of the porosity and permeability of fractured reservoirs. The total porosity of the fracture is 0 to 8 × 10−3%, and the principal value of the planar permeability of the fracture is 0 to 3 × 10−3 µm2; the principal value of the fracture permeability is concentrated in the direction of 65 to 70° east-northeast. The simulated fracture porosity stress sensitivity index is distributed between 0 and 0.2, and the fracture permeability stress sensitivity index is distributed between 0 and 0.4. The Young’s modulus of the rock, in-situ stress parameters, and sound velocity in the rock are important factors affecting the fracture stress sensitivity.
