Antenatal corticosteroid administration-to-birth interval and neonatal outcomes in very preterm infants: A secondary analysis based on a prospective cohort study
Authors: Wang Duan , Ming Li , Zhu Yong 
Published: February 2023

Introduction
Despite the prevalent use of antenatal corticosteroids (ACS) to prevent preterm infants’ adverse neonatal complications, there is currently no consensus on administration-to-birth intervals of ACS. International guidelines broadly agree that the administration of antenatal corticosteroids should be within 7 days prior to preterm birth. However, there is little evidence to support narrower optimal ACS administration-to-birth interval time. This study was undertaken to investigate the association between the administration-to-birth interval of ACS which is bounded by 48 hours and neonatal outcomes in very preterm infants.

Materials and methods
This is a single-center prospective observational study. Data were collected prospectively from eligible infants from January 2008 to April 2014 at the Santa Clara Valley Medical Center, neonatal outcomes were compared between two groups based on the interval of antenatal corticosteroid administration-to-birth: the interval of <48h, and the interval of >48h. It was noted that the entire study was completed by Dongli Song et al., and uploaded the data to the DATADRYAD website. The author only used this data for secondary analysis.

Results
After adjusting potential confounders (gestational age, sex, birth weight, duration of cord clamping and delivery mode), the interval of >48h group compared to the interval of <48h group had significant reductions in mortality (OR: 0.17; 95% CI: 0.05–0.59), any retinopathy of prematurity (OR: 0.36; 95% CI: 0.16–0.82), severe retinopathy of prematurity (OR: 0.07; 95% CI: 0.01–0.45), any intubation (OR: 0.39; 95% CI: 0.20–0.75) and higher 1 min Apgar (β: 0.56; 95% CI: 0.10–1.02).

Conclusion
This study shows that in very preterm infants, compared with the interval of ACS<48h, the interval of ACS>48 hours has a significant health promotion effect.
Making sense of and working with COVID-19 related guidelines and information in Danish general practice–A qualitative study
Authors: Andersen Julie Høgsgaard , Møller Anne , Due Tina Drud 
Published: February 2023

Background
Attempts to manage the COVID-19 pandemic have involved a massive flow of guidelines and information to health professionals on how to reorganize clinical work and handle patients with COVID-19. The aim of this paper is to investigate how Danish general practitioners (GPs) made sense of and worked with guidelines and associated information on COVID-19 in the first months of the pandemic.

Methods
We conducted qualitative interviews with 13 GPs in the beginning of the pandemic and again approximately three months later. Between the two interviews, they wrote daily notes for 20 days. Interviews were audio-recorded and transcribed, and the material was analyzed using thematic network analysis.

Results
The interviewed GPs found the situation urgent and serious, and they spent a lot of time reading and working with COVID-19 related guidelines and associated information. Keeping up-to-date with and implementing guidelines was challenging due to the many sources of information and the constant guideline revisions. The GPs were able to assess patients’ risk status but were challenged by the changing guidelines regarding this. The GPs found that deciding whether a COVID-19 patient needed to be admitted to hospital was relatively straightforward. An important final challenge was discrepancies between the government’s public announcements regarding which patients could be tested for COVID-19, the guidelines provided to GPs, and the local testing capacities, which gave GPs extra work.

Conclusion
In an urgent situation like the COVID-19 pandemic it is crucial to secure good communication between the government, health authorities, professional medical societies, and health professionals. Improved practices of collaboration between health authorities and professional societies could improve communication in future health crises and relieve GPs of some of the work involved in keeping up-to-date with information flows, constantly reviewing new guidelines, and dealing with communicative inconsistencies.
Correlating global trends in COVID-19 cases with online symptom checker self-assessments
Authors: Zobel Marc , Knapp Bernhard , Nateqi Jama , Martin Alistair 
Published: February 2023

Background
Online symptom checkers are digital health solutions that provide a differential diagnosis based on a user’s symptoms. During the coronavirus disease 2019 (COVID-19) pandemic, symptom checkers have become increasingly important due to physical distance constraints and reduced access to in-person medical consultations. Furthermore, various symptom checkers specialised in the assessment of COVID-19 infection have been produced.

Objectives
Assess the correlation between COVID-19 risk assessments from an online symptom checker and current trends in COVID-19 infections. Analyse whether those correlations are reflective of various country-wise quality of life measures. Lastly, determine whether the trends found in symptom checker assessments predict or lag relative to those of the COVID-19 infections.

Materials and methods
In this study, we compile the outcomes of COVID-19 risk assessments provided by the symptom checker Symptoma (www.symptoma.com) in 18 countries with suitably large user bases. We analyse this dataset’s spatial and temporal features compared to the number of newly confirmed COVID-19 cases published by the respective countries.

Results
We find an average correlation of 0.342 between the number of Symptoma users assessed to have a high risk of a COVID-19 infection and the official COVID-19 infection numbers. Further, we show a significant relationship between that correlation and the self-reported health of a country. Lastly, we find that the symptom checker is, on average, ahead (median +3 days) of the official infection numbers for most countries.

Conclusion
We show that online symptom checkers can capture the national-level trends in coronavirus infections. As such, they provide a valuable and unique information source in policymaking against pandemics, unrestricted by conventional resources.

Zusammenfassung
Im Rahmen der Fördermaßnahme „Innovative Konzepte zum Ausbau der China-Kompetenz an deutschen Hochschulen“ des Bundesministeriums für Bildung und Forschung, wurde 2018 ein China-Kompetenzzentrum an der TU Clausthal errichtet. Mit dem Ziel die deutsch-chinesische Zusammenarbeit zu stärken, sollten u. a. der Auf- und Ausbau von China-Kompetenz aller Hochschulangehörigen als auch die Kooperationen mit bestehenden aber auch neuen chinesischen Partnerhochschulen intensiviert werden. Die dazu im Rahmen der Eröffnung des China-Kompetenzzentrums initiierte, seither jährlich stattfindende China Woche hat sich dabei in kürzester Zeit zu einer überregional und international bekannten Veranstaltung entwickelt. Sie versteht sich als interkulturelle Kommunikationsplattform für einen konstruktiven Dialog, an dem sich prominente Akteur*innen der Wissenschaft, Wirtschaft und Politik aus Deutschland und China beteiligen.
Der folgende Beitrag beschreibt den genauen Entstehungshintergrund und analysiert die Entwicklung der Veranstaltung seit 2018, um schließlich den Beitrag zur interkulturellen Kommunikation zwischen Deutschland und China darzustellen.
Ist ein Verhandlungstraining für den Umgang mit chinesischen Geschäftsleuten effektiv? – Eine Analyse der Überzeugungen und Bedürfnisse von Führungskräften aus drei Ländern
Authors: Zhu Xiaoshu , Gao Chang , Kopernik Martina 
Published: February 2023

Zusammenfassung
Vor der China International Import Expo (CIIE) im November 2021 führten wir eine Studie mit Geschäftsleuten aus Brasilien, Mexiko und Deutschland durch, die eine auf Verhandlungen mit Chinesen ausgerichtete Fortbildung angefragt hatten, um gut auf diese Messe vorbereitet zu sein. Um mehr über deren besonderen Bedürfnisse herauszufinden, verteilten wir einen Fragebogen vor dem Verhandlungstraining, in dem wir ihre Ansichten über Verhandlungen im Allgemeinen und ihre genauen Bedürfnisse in Bezug auf Verhandlungen mit chinesischen Geschäftsleuten erfragten. Unserer Analyse der 57 Rückantworten zufolge interessierten sich die befragten Geschäftsleute am meisten für die Entwicklung von Verhandlungsdenken, den Umgang mit vertragsbezogenen Themen und den Aufbau von Vertrauen und stabilen Geschäftsbeziehungen. Hinsichtlich der Verhandlungen mit chinesischen Geschäftsleuten legten die Teilnehmer einen besonderen Fokus auf das Erkennen von Entscheidungsträgern im chinesischen Verhandlungsteam, den Umgang mit rechtlichen Belangen in Verhandlungen und die typisch chinesischen moralischen Wertvorstellungen in Bezug auf das Geschäftsleben. In Kooperation mit dem Trainingsanbieter wurden unsere Studienergebnisse dazu verwendet, um das nachfolgende Training auf die Bedürfnisse der zukünftigen Teilnehmer zuzuschneiden. Um die Auswirkungen eines solchen modifizierten Trainings zu untersuchen, baten wir die ehemaligen Fortbildungsteilnehmer – nach der Gelegenheit, das Gelernte im realen Umfeld der CIIE anzuwenden – in einem zweiten Fragebogen verschiedene Aspekte ihres Trainings zu evaluieren und sich zu zukünftigen Fortbildungsinteressen zu äußern. Das äußerst positive Feedback der 49 Umfrageteilnehmer bestärkt unsere Annahme, dass die Inhalte von Verhandlungstrainings auf die Bedürfnisse der Teilnehmer zugeschnitten sein sollten und dass wir einen möglichen Weg aufgezeigt haben, wie solche Daten erhoben und evaluiert werden können.

Interbank Connections, Bank Risk and Returns
Authors: Albinali Abdulla Ahmed , Ghosh Saibal 
Published: February 2023

Abstract
Using data on MENA country-banks, we study how interbank connections affect bank risk and returns. The findings indicate that interbank connections are determinantal to bank stability in the MENA region during periods of crisis, supportive of contagion effects. There is also a dampening impact on profitability. Over and above, the evidence for Islamic banks is supportive of contagion effects during the crisis, although their profitability is higher as well. Furthermore, macroprudential policies appear to exert a salutary impact on bank behavior, although this impact differs across the response variable: being effective for credit exposures with profits as the outcome and for funding exposure when non-performing loan ratio is the outcome variable.

The Unique Solution to the Differential Equations of the Fourth Order with Non-Homogeneous Boundary Conditions
Authors: B Madhubabu , Sreedhar N. , Prasad K.R. 
Published: February 2023

This research paper aims to establish the uniqueness of the solution to fourth-order nonlinear differential equations
v(4)(x) + f (x,v(x)) = 0, x ε [a,b],
with non-homogeneous boundary conditions
where 0 ≤ a < ζ < b, the constants α, ???? are real numbers and f : [a,b] x R →R is a continuous function with f (x, 0] ≠ 0. Using the sharper bounds on the integral of the kernel, the uniqueness of the solution to the problem is established based on Banach and Rus fixed point theorems on metric spaces.

Operational analysis of electric field mills as lightning warning systems in Colombia
Authors: Aranguren D. , López J. , Pérez E. , Herrera J. , Aragón L. , Torres H. 
Published: February 2023

Electrostatic field measurements taken in Bogotá, Colombia, during thunderstorms in November (the rainy season due to inter-tropical confluence zone over central Colombia) were used to study the performance of an isolated electric field sensor and analyse its most important operational characteristics. The distances from each flash to the studied sensor were obtained by using the Colombian lightning location system. The ΔE cf distance ratio led to defining a charge model which could be used as a reference for calibrating other electrostatic field sensors to be used as lightning warning systems.
The structural behaviour of laminated-guadua panels under parallel plane loads
Authors: Pinilla Rodríguez Juan Jacobo , Takeuchi Tam Caori Patricia 
Published: February 2023

The Universidad Nacional de Colombia "Analysis, Design and Materials - GIES" research group tested two types of panels made from Guadua angustifolia Kunth and poly vinyl acetate (PVA) as a first step in studying the behaviour of laminated guadua frames having panels of the same material under seismic load: type 1 panels had a solid cross-section and type 2 panels a sandwich cross-section. Each type of panel had three different heights and 10 replicates were tested for each type and height (60 trials in total). Each panel's load compared to displacement curve was found; 0.34m and 0.63m type1 panels had initial elastic behaviour followed by inelastic behaviour while 0.98 m panels made of both types had an almost completely elastic behaviour until failure. All panels became crushed at their base; however, the main failure mechanism was warping.

Published: February 2023

This work studied the effect of the number of generations of the IBUN 91.2.98 Leuconostoc mesenteroides strain on enzyme complex production. The subculturing technique was used on a medium which had been designed specifically for this organism for producing an enzyme complex. The effect was indirectly determined by monitoring microorganism growth and measuring the glucosyltransferase and hydrolytic activity of an enzyme extract obtained from such culture. There were 40 subcultures, representing 196 generations of IBUN 91.2.98 Leuconostoc mesenteroides. The results led to establishing that the extract's higher enzymatic activity (from 4 to 6 U/mL) was reached at the end of the culture's exponential phase and that this activity was stable during subculturing, confirming that there was no variation in strain regarding enzyme extract production until such number of generations had occurred, thereby not being limited to scaling-up to 8,000 litres.
Historia Kościoła w myśli Marsyliusza z Padwy
Authors: Pawlak Mieszko 
Published: February 2023

The History of the Church in the Thought of Marsilius of Padua The article discusses the issue of Church history in the thought of Marsilius of Padua, one of the most original thinkers of the Middle Ages. The author of the article presents the specific vision of the history of Christianity outlined by Marsilius, beginning with his view of the early Church as the community in which the primacy of Roman bishops emerged gradually – not by the will of God, but with a human decision motivated by pragmatic reasons. According to Marsilius, the reign of Constantine the Great marked a turning point in the history of Christianity, since it enabled identification of the Church and the state, as a result of which the communitas fidelium became a perfect community. On the other hand, Constantine supposedly initiated a process of gradual degeneration of the Church through his reckless donation given to Pope Sylvester and his successors. Taking into account the thought Marsilius of Padua in its entirety, the author tries to demonstrate that this vision of the history of Christianity was in fact an instrument of political propaganda, aimed at justifying the full subordination of the Church to the state.
Historia Eucharystii w pierwszych wiekach chrześcijaństwa w świetle wybranych źródeł (II–IV w.)
Authors: Janicki Jan Józef 
Published: February 2023

The author presents in his article the Eucharist in early centuries of the Church in the light of the most important sources available today. He shows that it is a reality very rich in the theological, liturgical and pastoral aspects. The author analyzes and presents the most important documents such as the Didache. Science of the Twelve Apostles (I/II), Apology of St. Justin Martyr (150), Apostolic Tradition of St. Hippolytus of Rome (215), Records of Martyrs. The martyrs of the Sunday Eucharist in Abitene (304) and Apostolic Constitutions with the so called “klementynian” mass (380), which division into the mass of the catechumens (currently liturgy of the word) and the mass of the faithful (now the liturgy of the Eucharist) survived to the new Roman Missal (1970) edited by the Second Vatican Council (1962–1965). Analyzed by the author of this article the most important source of the Eucharistic of the early centuries of the Church (II–IV c), confirms the teaching of pope St. John Paul II (1978–2005), that “the Eucharist, understood as Christ’s saving presence in the community of the faithful and its spiritual food, is the most precious possession which the Church has on the roads of history” (John Paul II, encyclical “Ecclesia de Eucharistia”.
Percepciones de los docentes en torno a la formación de estudiantes del nivel medio superior con capacidades diferentes
Authors: Ávila Valdez Cristina , Rodelo- Pérez Jesús Manuel 
Published: February 2023

El presente trabajo forma parte de un estudio más amplio que aborda la educación inclusiva de alumnos con necesidades especiales en una institución pública del nivel medio superior. Esta investigación surge de considerar la importancia de las estrategias educativas del profesorado en el aprendizaje de los estudiantes, lo cual es de especial relevancia en los estudiantes con capacidades diferentes pues ellos requieren de una atención diferenciada dependiendo de su discapacidad. El objetivo es describir las percepciones de los docentes con relación a las estrategias educativas implementadas en la formación de estudiantes del nivel medio superior con capacidades diferentes en el contexto de una preparatoria pública. Con base en una metodología cualitativa (Goetz y LeCompte, 1988) se aplicaron entrevistas semiestructuradas a los docentes del grupo estudiado y al coordinador del programa. A través de las percepciones de los docentes que laboran con los alumnos discapacitados se analizó el sentido de las prácticas pedagógicas configuradas para un sujeto con discapacidad y las rupturas con las lógicas de inclusión educativa. En los resultados fue posible dimensionar el panorama de sus prácticas y describir las tensiones entre lógicas diversas y contradictorias. En apartado de conclusiones, se manifiesta que las problemáticas requieren atención inmediata, independientemente de la situación que exista para capitalizarlas de forma positiva. Las narrativas aludieron a casos exitosos en determinadas acciones donde los profesores son protagonistas de estos logros y manifestaron su aporte entendiendo la inclusión no como una problemática, sino como una experiencia de vida que enriquece su crecimiento personal.
