Historia Zakładu Radiologii Pediatrycznej Warszawskiego Uniwersytetu Medycznego (część 1)
Authors: Batycki Krzysztof 
Published: April 2024

Praca prezentuje historię Zakładu Radiologii Pediatrycznej Warszawskiego Uniwersytetu Medycznego, mieszczącego się w Samodzielnym Publicznym Dziecięcym Szpitalu Klinicznym przy ul. Marszałkowskiej 24 (róg ul. Litewskiej). Jedynym, obszernym opracowaniem historii Zakładu, jakie powstało do tej pory, jest bogaty w bezcenne informacje tekst profesora Andrzeja Marcińskiego, opublikowany kilkukrotnie w latach 1991-1997. Niniejsza praca w dużej mierze opiera się na nim – rozbudowano omówione już tematy, zwłaszcza o wydarzenia, które miały miejsce po jego napisaniu. Ponieważ działalność Zakładu zawsze była ściśle związana, bardziej lub mniej formalnie, z pracą Zakładu Radiologii Szpitala przy ul. Działdowskiej 1, zarys jego historii również został przedstawiony. Do napisania pracy autor wykorzystał przede wszystkim nieliczne publikacje dotyczące historii Zakładu Radiologii Pediatrycznej oraz materiały pochodzące ze zbiorów Archiwum Warszawskiego Uniwersytetu Medycznego. Całość wzbogacił o zebrany przez siebie rozległy zbiór wspomnień pracowników Zakładu i osób w inny sposób z nim związanych. Szczegółowo omówione zostało 60 lat historii Zakładu, od jego założenia w 1951 r. do 2011 r. Zakład powstał na bazie dwóch istniejących już wcześniej pracowni rentgenowskich, dlatego pokrótce omówiona została także ich historia. Całość opracowania podzielono chronologicznie, na trzy główne części, w zależności od tego, kto pełnił funkcję kierownika Zakładu. Szczególnie obszerna część tekstu poświęcona jest ludziom tworzącym Zakład, nie tylko lekarzom – szeroko omówiona została praca techników elektroradiologów oraz zmiany, jakim jej specyfika podlegała na przestrzeni dekad.
Liquidity Risk and Currency Premia
Authors: Söderlind Paul , Somogyi Fabricius 
Published: April 2024

The currency market is the world’s largest financial market by trading volume. We show that even in this highly liquid market, exposure to liquidity risk commands an economically significant risk premium of up to 3.6% per year. Liquidity risk is not subsumed by existing currency risk factors and successfully prices the cross section of currency excess returns. Moreover, we find that liquidity risk and carry trade premia are correlated, although this correlation is limited to static rather than dynamic carry trades. Building on this result, we propose a liquidity-based explanation for the carry trade, which adds significant explanatory power to existing theories. This paper was accepted by Lukas Schmid, finance.

On Constrained Mixed-Integer DR-Submodular Minimization
Authors: Yu Qimeng , Küçükyavuz Simge 
Published: April 2024

Diminishing returns (DR)–submodular functions encompass a broad class of functions that are generally nonconvex and nonconcave. We study the problem of minimizing any DR-submodular function with continuous and general integer variables under box constraints and, possibly, additional monotonicity constraints. We propose valid linear inequalities for the epigraph of any DR-submodular function under the constraints. We further provide the complete convex hull of such an epigraph, which, surprisingly, turns out to be polyhedral. We propose a polynomial-time exact separation algorithm for our proposed valid inequalities with which we first establish the polynomial-time solvability of this class of mixed-integer nonlinear optimization problems.

Published: April 2024

Objective: Accurate assessment of burn depth and burn wound healing potential is essential to determine early treatments. Infrared thermography (IRT) is a non-invasive and objective tool to do this. This systematic review evaluated the accuracy of IRT to determine burn wound healing potential. Method: This systematic review and meta-analysis used MEDLINE, EMBASE, CINAHL, PEDro, DiTA and CENTRAL databases. IRT data were extracted from primary studies and categorised into four cells (i.e., true positives, false positives, true negatives and false negatives). Subgroup analysis was performed according to methods used to capture thermal images. Results: The search strategy identified 2727 publications; however, 15 articles were selected for review and 11 for meta-analysis. In our meta-analysis, the accuracy of IRT was 84.8% (63% sensitivity and 81.9% specificity). Conclusion: IRT is a moderately accurate tool to identify burn depth and healing potential. Thus, IRT should be used carefully for evaluating burn wounds.

Authors: Paulander Ann-Sofie , Lindholm Christina , Torgrip Ralf , Kumlin Maria , Eulau Louise 
Published: April 2024

Objective: To determine whether person-centred music (PCMusic) contributes to reducing pain during painful leg ulcer dressing change procedures indicated by: decreased levels of indicators related to stress; decreased pain scores; and a more favourable treatment climate during the dressing change procedure. Method: A case study of a 51-year-old female patient with chronic inherited disease weakening her connective tissues. Quantitative data entailed temporal measurements of stress indicators including: heart pulse rate; oxygen saturation (SpO2); saliva cortisol; and a visual analogue scale (VAS). Qualitative data comprised phenomenological treatment descriptions and patient/licensed practical nurse (LPN) questionnaires. Results: The patient's body temperature remained steady throughout all treatments. Blood pressure was excluded due to missing data. No significant pulse rate differences in relation to music/no music could be observed during treatment. Comparing PCMusic to the patient's own other music (POOM), the pulse rate was greater in both magnitude and variation when the patient listened to POOM. Oxygen saturation showed no significant difference between PCMusic and music/no music. No significant difference was observed pre-/post-debridement with music. Similarly, no significant difference was observed pre-/post-debridement with no music. Treatment with no music showed the highest VAS score; PCMusic treatments had the lowest scores. Qualitative data showed that both patient and LPNs found that PCMusic decreased pain during dressing change. Conclusion: The results of this case study indicate that PCMusic is a suitable complementary treatment to decrease patient pain. Patients' general health status is important when using quantitative stress/pain marker measurements. For cohort selection in future studies, we suggest healthy patients undergoing slightly painful or unpleasant treatments, patients in postoperative care and obstetric care.

Authors: Erminelli Davide , Mangini Chiara , Zarantonello Lisa , Angeli Paolo , Montagnese Sara 
Published: April 2024

INTRODUCTION:
We aimed to assess the reliability of a qualitative approach to overt hepatic encephalopathy (OHE) diagnosis compared with the semiquantitative, and recommended one.

METHODS:
The above 2 methods were compared in 411 outpatients (71% males, 60 ± 10 years, model for end-stage liver disease 13.5 ± 5.0).

RESULTS:
Of the 73 patients with OHE on quantitative assessment, 19 (26%) were missed on qualitative assessment, with no difference in the likelihood of the physician missing grades II or III. Sixty-eight (20%) of the 270 patients with no OHE on quantitative assessment were wrongly qualified as having OHE.

DISCUSSION:
Qualitative clinical evaluation of OHE is not reliable, and recommendations should be followed.
Metabolic Sequelae and All-Cause Mortality in Chronic Pancreatitis With and Without Prior Acute Pancreatitis: A Nationwide Population-Based Cohort Study
Authors: Cook Mathias Ellgaard , Bruun Niels Henrik , Davidsen Line , Vestergaard Peter , Drewes Asbjørn Mohr , Olesen Søren Schou 
Published: April 2024

INTRODUCTION:
The purpose of this study was to investigate the risk of metabolic sequelae and all-cause mortality in a population-based cohort of chronic pancreatitis (CP) patients with and without prior acute pancreatitis (AP).

METHODS:
We used nationwide health registries to identify all Danish residents (18 years and older) with incident CP from 2000 to 2018. Information on AP/CP diagnoses, metabolic sequelae (post-pancreatitis diabetes mellitus [PPDM], exocrine pancreatic dysfunction, and osteoporosis), and all-cause mortality were obtained from Danish national health registries. CP cases were stratified based on the presence of AP before CP diagnosis. The risk of metabolic sequelae and all-cause mortality was expressed as hazard ratios (HRs) with 95% confidence intervals (CIs), calculated using multivariate Cox proportional hazards models.

RESULTS:
A total of 9,655 patients with CP were included. Among patients with CP, 3,913 (40.5%) had a prior AP diagnosis. Compared with patients without a history of AP, patients with prior AP had a decreased risk of death (HR 0.79, 95% CI 0.74–0.84), which was largely confined to the initial period after CP diagnosis. Patients with prior AP had an increased risk of PPDM (HR 1.53, 95% CI 1.38–1.69), which persisted for up to a decade after CP diagnosis. No overall differences in risk were observed for exocrine pancreatic dysfunction (HR 0.97, 95% CI 0.87–1.07) and osteoporosis (HR 0.87, 95% CI 0.74–1.02).

DISCUSSION:
This nationwide study revealed that most of the patients with CP have no prior episode(s) of AP, indicating that an attack of AP sensitizing the pancreas is not essential for CP development. CP patients with and without prior AP have different risk profiles of PPDM and all-cause mortality.
Recursos pedagógicos acessíveis para o ensino de química de alunos com deficiência visual: uma revisão sistemática entre 2007 e 2022

Published: April 2024

O ensino de Química para pessoas com deficiência visual (DV) necessita de uma abordagem diferenciada, que envolve a utilização de Recursos Pedagógicos Acessíveis (RPA) para auxiliar na compreensão de imagens e modelos, a fim de proporcionar equidade nas condições de acesso ao conhecimento. E é imprescindível o uso de RPA no ensino de Química de alunos com DV, para promover o acesso equitativo aos conteúdos. Assim, este trabalho visa analisar recursos acessíveis voltados ao ensino de química para alunos com DV, com o intuito de sistematizá-los em função de: conteúdo, nível educacional, público a que se destina e se atende aos critérios de qualidade definidos pelo MEC. A pesquisa constituiu-se de uma investigação bibliográfica, baseada na análise de conteúdo. Foi realizada uma Revisão Sistemática Literária que teve como questão principal “A produção de RPA para pessoas com DV voltados ao ensino de Química nos últimos quinze anos, no Brasil”. A base de dados utilizada para definição do corpus da pesquisa foi o Portal de Periódicos da CAPES, no interstício 2005-2020. Sete trabalhos atenderam aos critérios de inclusão do protocolo. Todos os RPA construídos abordam temáticas de Química para o Ensino Médio. A maioria dos recursos não atende, simultaneamente, as necessidades específicas de alunos com baixa-visão e cegueira. Como também, nem todos atendem aos critérios de qualidade do MEC. Não foram encontrados trabalhos no interstício 2005-2013. Revelando que a preocupação em compartilhar resultados de práticas inclusivas, direcionadas ao Ensino de Química, tomou fôlego apenas nos últimos oito anos. Os conteúdos abordados giram em torno de Atomística e Tabela Periódica, revelando que ainda há muitos conteúdos que carecem de uma abordagem inclusiva.

Published: April 2024

How do we make judgements about the quality of online courses? Checklists and rubrics are commonplace in Higher Education for establishing and measuring design features of online courses. They are created and used by institutions, academics, and educational designers to standardise measures for quality online course design. Despite an intensifying spotlight on quality learning and teaching in Higher Education, no large-scale review of course quality instruments has occurred. This scoping review aimed to ascertain the conceptions of quality being promoted by course quality evaluation instruments and the capability-building resources that underpin these instruments.

Seventy-five instruments used to measure quality in online course design in Higher Education were identified via a systematic search. These instruments were charted and coded. This paper reports on findings that summarise the key attributes of the course quality evaluation instruments, conceptualises a shared definition of course quality, and proposes specific core criteria for measuring course quality under the domains of learning design, assessment and evaluation, usability and accessibility, social interaction, and technology. This scoping review found a concerning underrepresentation of capability-building resources associated with course quality instruments and recommends the capability-building potential of these tools shifting them from compliance checkers to enable skills development.
Analysis and numerical simulation of fractional-order blood alcohol model with singular and non-singular kernels
Authors: Prakash Amit , Kalyan Neha , Ahuja Sanjeev 
Published: April 2024

Abstract
In this manuscript, we examine the blood alcohol model to investigate the dynamics of alcohol concentration in the human body. The classical model of blood alcohol concentration is converted into the fractional model by using Caputo, Caputo-Fabrizio (CF), and Atangana-Baleanu-Caputo derivatives. The existence and uniqueness theory for the model’s solution is constructed using the Banach fixed point theory. Also, the stability of the solution is established by Ulam-Hyers conditions. For the numerical simulation of the considered model, the Adams-Bashforth method with a two-step Lagrange polynomial is used and the numerical solution of the model with three different derivatives is presented in the tabular and graphical form. The comparison between the exact solution and observed solution is made by root mean square technique which is found to be in good agreement. Finally, the results from the three fractional derivatives are also compared with the exact data, which revealed that the CF fractional derivative performs better than the other two fractional derivatives.
Modelling the adverse impacts of urbanization on human health
Authors: Pandey Prasoon , Uniyal Lubhna , Sharma Sandeep 
Published: April 2024

Abstract
Urbanization has been a growing trend for decades, but the Coronavirus disease 2019 (COVID-19) pandemic has accelerated this trend in several ways. In many countries, the pandemic has prompted significant investments in urban health infrastructure, including hospitals, clinics, and public health facilities. Also, there are many studies suggesting that COVID-19, urbanization, and chronic diseases are interconnected in several ways, and addressing one aspect requires a comprehensive approach that considers the interconnectedness of these factors. To date, there are no studies depicting COVID-19 as a cause of emerging chronic diseases within the urban population. To address this sensitive issue, we propose a mathematical model in which we divide the total human population into three compartments: susceptible, diseased, and recovered. We have obtained the equilibrium points of the model and the conditions for their local stabilities. A suitable Lyapunov function has been used to derive the condition for the global stability of the nontrivial equilibrium point. A detailed numerical simulation of the model has been carried out, which is followed by sensitivity analysis of the model system.
Heterogeneity characterization of commercial structural papers
Authors: Considine John , Keller D. Steven , Arvanitis Matthew A. , Tang Xiaoyan 
Published: April 2024

Abstract
Evaluation of physical and mechanical heterogeneity in commercial paperboards is needed to promote their use in structural applications, especially within the field of packaging. Understanding the range of their behaviors is needed to compete with other materials in the current marketplace and expand in others. This work describes the physical and stiffness heterogeneities of twelve commercial materials using tensile tests in the cross-machine direction and several inverse analyses. The effects of grammage, thickness, and apparent density on tensile stiffness were evaluated in both the linear elastic and nonlinear regimes. Thickness and density provided the best explanation for elastic heterogeneous behavior in most of the materials; local grammage was not the best descriptor for any material. The analyses used here were not able to provide a good explanation of the nonlinear behavior, which was attributed to the development of large shear strains within the materials as they neared failure. This work provides a methodology for additional heterogeneous behavior examinations.
The Burr distribution as an asymptotic law for extreme order statistics and its application to the analysis of statistical regularities in the interplanetary magnetic field
Authors: Bening Vladimir , Korolev Victor , Sukhareva Natalia , Xiaoyang Hong , Khaydarpashich Ruslan 
Published: April 2024

Abstract
The representability of the Burr distribution as a mixture of Weibull distribution is studied in order to justify its utility for modelling the statistical regularities in extreme values registered in non-stationary flows of informative events. A result of [24] is improved by extending the domain of admissible values of the parameters which provide the representability of the (generalized) Burr distribution as a scale mixture of the Weibull distribution. This result gives an argument in favour of application of the Burr distribution as a model of statistical regularities of extreme values registered within moderate regular time intervals, say, daily (short-term) extremes. In turn, if we are interested in the statistical regularities of the behaviour of the absolute extreme observation over a long period, say, a decade (the long-term extreme), then it can be noted that the daily extreme values form a sample of the Burr-distributed random variables. As is known, the Burr distribution belongs to the domain of max-attraction of the Fréchet distribution. The problem of improving the accuracy of the approximation of the distribution of the absolute extreme by the Fréchet distribution by the construction of an asymptotic expansion for the distribution of the extreme order statistics in the sample of independent identically Burr-distributed random variables is also considered. These results are illustrated by an example of fitting the Burr distribution to the data representing the extreme values of characteristics of the interplanetary magnetic field.

We study periodic trajectories of nonlinear dynamical systems considered as models of the simplest molecular repressilator. In the phase portraits of these systems, we find hidden attractors and nonlocal oscillations. The cases of nonuniqueness of cycles in these portraits are described as well.
The value of language skills in Latvia: From socio-economic inequality to multilingual awareness
Authors: Rozenvalde Kerttu , Martena Sanita 
Published: April 2024

Abstract
This paper investigates the opposition between the realities and ideologies surrounding multilingualism in Latvia. Building mostly on Bourdieu’s theory of language in society, and multilingual awareness as a concept, we study the socio-economic value of multilingual repertoires in a multilingual setting (Latvia), and language users’ awareness of the link between their language competences (Latvian, Russian, English) and socio-economic status. By analysing sociolinguistic survey data, we demonstrate, firstly, that different multilingual repertoires are linked with differences in family income, level of education, and labour market position. Secondly, our data indicate that people generally do not acknowledge the link between their language skills and socio-economic status. To explore this further, we zoom in on language ideologies in formal education. We examine data on the multilingual awareness of Latvian language teachers from focus-group interviews and show that they tend to construe languages in competition, emphasise the symbolic value of Latvian, and ignore the multilingualism of their pupils and broader society. The study illuminates the dissonance between the multilingual realities of a post-Soviet EU country in which multilingual repertoires carry different values for individuals, and the Latvian-centred ideologies (disseminated by the teachers) that leave the presence of multilingualism and accompanying issues unacknowledged.
