Clinical characteristics of children with multisystemic inflammatory syndrome associated with COVID-19

Aim: Coronavirus disease 2019 (COVID-19) has become a public health threat to people all over the world in 2020 and 2021. The Centers for Disease Control and Prevention (CDC) and WHO (World Health Organization) have named a novel disease multisystem inflammatory syndrome in children (MIS-C). Herein we aimed to present a group of pediatric patients with MIS-C, who were followed up in our clinic. Material and Methods: We retrospectively reviewed the medical records of patients who were followed up at our University Hospital with the diagnosis of MIS-C between January 2021 and May 2021. Results: The mean age of 9 patients was 87.4 +/- 17.8 years (range 6-161 months);six of the patients were male. All patients had fever at admission. The duration of the fever was between 3 and 7 days. Four patients (44.4%) had terminal ileitis on ultrasonic examination. The laboratory tests of the patients revealed leukocytosis in 4 (44.4%) patients, anemia in 5 (55.5%) patients, thrombocytopenia in 1 (11.1%) patient, and a high CRP level in 8 (88.8%) patients. All patients had high sedimentation rates and procalcitonin levels. One (11.1%) patient was operated on for terminal ileitis. All patients were treated with steroids (1-2 mg/kg prednisolone) and IVIG (2gr/kg). Patients who needed ICU admission were also treated with vasoactive drug infusion (intravenous dopamine). Discussion: There is a need for increased awareness among pediatricians that MIS-C should come to mind, especially in patients with long-lasting fever and signs and symptoms that resemble Kawasaki disease.
New ultracool and halo white dwarf candidates in SDSS Stripe 82

Abstract : A 2.5 100 region along the celestial equator (Stripe 82) has been imaged repeatedly from 1998 to 2005 by the Sloan Digital Sky Survey (SDSS). A new catalogue of ~4 million light-motion curves, together with over 200 derived statistical quantities, for objects in Stripe 82 brighter than r~21.5 has been constructed by combining these data by Bramich, et al. This catalogue is at present the deepest catalogue of its kind. Extracting ~130,000 objects with highest signal-to-noise ratio proper motions, we build a reduced proper motion diagram to illustrate the scientific promise of the catalogue. In this diagram, disc and halo sub-dwarfs are well-separated from the cool white dwarf sequence. Our sample of 1049 cool white dwarf candidates includes at least eight and possibly 21 new ultracool H-rich white dwarfs (Teff < 4000 K) and one new ultracool He-rich white dwarf candidate identified from their SDSS optical and UKIDSS infrared photometry. At least 10 new halo white dwarfs are also identified from their kinematics.
Explaining the Concept of Learning Based on Reflection in Clinical Education: Scoping Review

Objective: This study was conducted with the aim of theoretically explaining the concept of reflection in medical science education in texts and identifying the dimensions and characteristics of education based on reflection and their application in clinical nursing education and existing models in 2021. Methods: This scoping review was conducted in five phases following the method developed by Denyer and Tranfield. The scope of the review was limited to Reflection and Reflective in nursing education. Using the keywords in combination and separately, they were searched in databases of ERIC/ www.iranmedex. com/ www.magiran. com/ www.irandoc. ac.ir/ www.sid. ir/ www.medlib. ir/ All Sciences/ Web of Science/Search Engines Google/Google scholar/Scopus/Ovid/ERIC/Wiley/PubMed and Science Direct from1970s to 2021. Results: Based on inclusion and exclusion criteria, 24 articles and documents were selected. During the theoretical explanation of the concepts and components of reflection in clinical nursing education, the model is abstracted. In this model: The Clinical education triangle has 3 main components in its three angles: patient, teacher, or tutor, and student. It is necessary that the sides of this triangle including teaching-learning, teaching-caring, and caring-learning to be formed in the best way and to serve the student and the patient. Conclusion: The results of this study emphasize the practical and constructive nature of knowledge in learning based on reflection and its special position so that by eliminating the gap between theory and practice in nursing education, one can see the excellence of the operational part of education and promotion of the level of health of the society by providing an appropriate performance of the nursing staff.
Tightening and Loosening of Macroprudential Policy, Its Effects on Credit Growth and Implications for the COVID-19 Crisis

In this study, we analyze the effects of macroprudential measures on bank lending in the European Union. We develop several dedicated macroprudential policy indices re ﬂ ecting different policy actions taken by the authorities in individual member countries, with the aim to affect credit activity in national banking sectors. In our empirical model, we measure responsiveness of gross loans in banks to selected macroprudential policy indices, taking into account a set of bank level and macroeconomic control variables. We use the Fitch Connect bank level dataset with ﬁ nancial statements for 3434 European banks with 18,616 observations and macroeconomic data provided by the World Bank and IMF statistics covering the period between 2000 and 2017. Information on the use of macroprudential instruments is taken from a new macroprudential policy database, MaPPED, gathered and published by European Central Bank, where we were able to extract the information on both timing and the direction of use of the macroprudential policy instruments. Our ﬁ ndings show that macroprudential instruments can be used effectively for regulatory modulation of credit activity in banks, with some ﬂ uctuations in the level of the effectiveness through the business cycles. Therefore, in loosening cycles, macroprudential measures are found to be strongly and positively associated with bank lending. On the other side, tightening actions are found to have a downward effect on bank lending, while these effects are less pronounced. These results are of great importance in the current crisis arising from the impact of COVID-19, as policymakers are trying to support the economy by easing macroprudential regulatory constraints to ensure lending to the real sector.
Prediction of Blood Glucose Level Using Nonlinear System Identification Approach

Predicting the blood glucose level of type 1 diabetes mellitus of patients could prevent hypo/hyperglycemia incidents that are threats for the patients with this disease. A nonlinear system identification approach is proposed in this work to develop a mathematical model, which can be used to predict the blood glucose level over a given period with high accuracy. More specifically, the Hammerstein Box-Jenkins model is used to approximate the system, where two infinite impulse response filters represent the linear and noise processes, and a polynomial basis function represents the nonlinearity. The proposed identification method is based on the Steiglitz-McBride approach to predict the model parameters. Moreover, a simulation software licensed by the USA Food and Drug Administration that simulates the dynamics of the glucose-insulin system metabolism inside the body, called Type I Diabetes Metabolic Simulator (T1DMS), was used to generate the data. Thirty subjects of different age groups were considered, and the data was generated for a week with a sample per minute, i.e. 302430 data points. This data was then processed using a developed MATLAB code to predict the blood glucose level. Various scenarios were established to validate the proposed approach. The simulations showed very promising results with a very low average root mean square error of 1 mg/dl, which is seven times less compared to other prediction techniques. Other cost functions have also been used and they showed very good results. In the future, this approach can be embedded in closed-loop continuous blood glucose monitoring systems in order to give alerts to the patients and help in calculating the needed insulin dose.
Study of the Lipid Profile of ATCC and Clinical Strains of Staphylococcus aureus in Relation to Their Antibiotic Resistance

A number of reports have indicated a relationship between bacterial resistance to antibiotics and their lipid composition. In the present study, we characterized the lipid profiles of American Type Culture Collection (ATCC) and clinical strains of Staphylococcus aureus and its correlation with antibiotic resistance and hydrophobicity. The following strains were used: S. aureus ATCC 6538P, S. aureus ATCC 43300 (MRSA), seven clinical strains from the pharynges, two strains from duodenal ulcers, four strains from hip prostheses, and one strain from the conjunctiva. Lipid-related differentiation was observed across the S. aureus strains: the higher abundance of anteiso-pentadecanoic acid (anteiso-C15:0) and anteiso-heptadecanoic acid (anteiso-C17:0), followed by iso-pentadecanoic acid (iso-C15:0), suggested that these were common lipids. Iso-tridecanoic acid (iso-C13:0) and anteiso-tridecanoic acid (anteiso-C13:0), iso-hexadecanoic acid (iso-C16:0) and anteiso-hexadecanoic acid (anteiso-C16:0), and all forms of octadecanoic acid (C18:0) were usually detected in low abundance. Strains isolated from pharynges showed the highest ratio of branched/straight chains. A distinction in two clusters based on the amount and type of bacterial lipids identified was obtained, which correlated to the antibiotic resistance, the strains origin, and the cell-surface hydrophobicity. We report a potential correlation between the lipid profile of S. aureus strains, site of infection, antibiotic resistance, and cell-surface hydrophobicity. These results, which still need further insights, could be a first step to identifying antibiotic resistance in response to environmental adaptation.
Natural bio-based products for wood coating and protection against degradation: A Review

Preservation of wood structures against degradation represents an old, and however, a new challenge. Wood, as a natural hybrid composite material, represents a versatile and widely exploited renewable resource for indoor and outdoor applications. Its constitutive biopolymers are subjected to intense and progressive oxidative degradation processes under environmental conditions of exposure, affecting wood’s native durability and generating significant structural and color changes, along with progressive diminution of its resistance against biological agents. One effective way to prevent wood degradation is to apply coating protective layers by chemical modification of the surface. In this context, increasing interest for improving wood coatings behavior under exposure to outdoor applications, when these are able to prevent or limit to a large extent the deleterious effects of environmental factors upon their performance, justifies enhanced research efforts to provide new effective solutions for sustainable wood protection. Recent trends in this area include use of bio-based natural products – extractives, oils, waxes, resins, biopolymers, biological control agents – for which the main classification criterion is represented by the type of protection provided, considering the large available variety of such formulations. The present paper focuses on the most recent literature data with significant assessment of specific topics related to these issues.
A Simulation‐Based Framework for Earthquake Risk‐Informed and People‐Centered Decision Making on Future Urban Planning

Numerous approaches to earthquake risk modeling and quantification have already been proposed in the literature and/or are well established in practice. However, most of these procedures are designed to focus on risk in the context of current static exposure and vulnerability, and are therefore limited in their ability to support decisions related to the future, as yet partially unbuilt, urban landscape. We propose an end‐to‐end risk modeling framework that explicitly addresses this specific challenge. The framework is designed to consider the earthquake (ground‐shaking) risks of tomorrow's urban environment, using a simulation‐based approach to rigorously capture the uncertainties inherent in future projections of exposure as well as physical and social vulnerability. The framework also advances the state‐of‐practice in future disaster risk modeling by additionally: (a) providing a harmonized methodology for integrating physical and social impacts of disasters that facilitates flexible characterization of risk metrics beyond physical damage/asset losses; and (b) incorporating a participatory, people‐centered approach to risk‐informed decision making. The framework is showcased using the physical and social environment of an expanding synthetic city. This example application demonstrates how the framework may be used to make policy decisions related to future urban areas, based on multiple, uncertain risk drivers.
How does discrimination occur in hospitality and tourism services, and what shall we do? A critical literature review

Purpose This study aims to critically review the research on the phenomenon of discrimination in hospitality and tourism services to identify the key thematic areas, scenarios, antecedents and consequences; to provide theoretical propositions for future research; and to propose practical strategies to reduce discrimination and to improve equality in the field. Design/methodology/approach This paper adopts the preferred reporting items for systematic reviews and meta-analyses guidelines to collect relevant academic work on discrimination in hospitality and tourism services from 1985 to 2020 and critically reviews and analyses the studies through bibliometric analysis, content analysis and critical analysis. Findings The findings show that the main sources of discrimination in hospitality and tourism services include sexism, racism, ethnocentrism, lookism and ego-altruism. Discrimination-related research has temporal and geographical variations. A research map is proposed to present existing knowledge of discrimination in hospitality and tourism services, which indicates that while the impacts (at the individual, organizational and institutional levels) of discrimination in hospitality and tourism services have been thoroughly researched, the nature and characteristics of the phenomenon remain context-based and poorly conceptualized. Practical implications An anti-discrimination guideline for hospitality and tourism practitioners is designed to cope with and eliminate discriminatory situations. This evidence-based guideline provides useful coping strategies based on the prevent–monitor–manage principle. Originality/value This paper is comprehensive in its scope, methodology and wide coverage of discrimination-related research in hospitality and tourism services. It is the first attempt to review this phenomenon in the existing literature and identifies the research gaps and future research agendas.
Analysis of the absorption spectra of epitaxial lead telluride and lead selenide layers

193 Abstract. By processing the optical transmission spectra, the index of refraction, and reflection and absorption coefficients of epitaxial PbTe and PbSe layers (grown on BaF2 (111) and NaCl (100) substrates, respectively, by molecular epitaxy with a “hot wall”) were measured sequentially by the elaborated scheme. The concentration of current carriers varied in the range from 10cm to 10cm. The analysis of the obtained absorption spectra was performed, and the squared absorption coefficients were straightened with the purpose to determine the forbidden gap width. Special emphasis is placed on the effect of high concentration of the current carriers on the type of dispersion of the index of refraction, the absorption by free carriers and the degeneration of the current carriers. An approach to correct determination of the forbidden gap width with the formal transition from the degenerated semiconductor to the no degenerate one by modification of the absorption coefficient was worked out. With limitation of the range of energy at which the absorption undergoes changes, additional absorption between the absorption edge and the absorption by free carriers increasing with the wavelength was revealed in the PbSe layers. For the PbTe layers with a lower concentration of current carriers, the additional absorption was found by the model analysis of transmission spectra at zero absorption.
Relativistic tidal properties of neutron stars

We study the various linear responses of neutron stars to external relativistic tidal fields. We focus on three different tidal responses, associated to three different tidal coefficients: (i) a gravito-electric-type coefficient $G{\ensuremath{\mu}}_{\ensuremath{\ell}}=[\mathrm{\text{length}}{]}^{2\ensuremath{\ell}+1}$ measuring the $\ensuremath{\ell}$th-order mass multipolar moment $G{M}_{{a}_{1}\dots{}{a}_{\ensuremath{\ell}}}$ induced in a star by an external $\ensuremath{\ell}$th-order gravito-electric tidal field ${G}_{{a}_{1}\dots{}{a}_{\ensuremath{\ell}}}$; (ii) a gravito-magnetic-type coefficient $G{\ensuremath{\sigma}}_{\ensuremath{\ell}}=[\mathrm{\text{length}}{]}^{2\ensuremath{\ell}+1}$ measuring the $\ensuremath{\ell}$th spin multipole moment $G{S}_{{a}_{1}\dots{}{a}_{\ensuremath{\ell}}}$ induced in a star by an external $\ensuremath{\ell}$th-order gravito-magnetic tidal field ${H}_{{a}_{1}\dots{}{a}_{\ensuremath{\ell}}}$; and (iii) a dimensionless ``shape'' Love number ${h}_{\ensuremath{\ell}}$ measuring the distortion of the shape of the surface of a star by an external $\ensuremath{\ell}$th-order gravito-electric tidal field. All the dimensionless tidal coefficients $G{\ensuremath{\mu}}_{\ensuremath{\ell}}/{R}^{2\ensuremath{\ell}+1}$, $G{\ensuremath{\sigma}}_{\ensuremath{\ell}}/{R}^{2\ensuremath{\ell}+1}$, and ${h}_{\ensuremath{\ell}}$ (where $R$ is the radius of the star) are found to have a strong sensitivity to the value of the star's ``compactness'' $c\ensuremath{\equiv}GM/({c}_{0}^{2}R)$ (where we indicate by ${c}_{0}$ the speed of light). In particular, $G{\ensuremath{\mu}}_{\ensuremath{\ell}}/{R}^{2\ensuremath{\ell}+1}\ensuremath{\sim}{k}_{\ensuremath{\ell}}$ is found to strongly decrease, as $c$ increases, down to a zero value as $c$ is formally extended to the ``black hole (BH) limit'' ${c}^{\mathrm{BH}}=1/2$. The shape Love number ${h}_{\ensuremath{\ell}}$ is also found to significantly decrease as $c$ increases, though it does not vanish in the formal limit $c\ensuremath{\rightarrow}{c}^{\mathrm{BH}}$, but is rather found to agree with the recently determined shape Love numbers of black holes. The formal vanishing of ${\ensuremath{\mu}}_{\ensuremath{\ell}}$ and ${\ensuremath{\sigma}}_{\ensuremath{\ell}}$ as $c\ensuremath{\rightarrow}{c}^{\mathrm{BH}}$ is a consequence of the no-hair properties of black holes. This vanishing suggests, but in no way proves, that the effective action describing the gravitational interactions of black holes may not need to be augmented by nonminimal worldline couplings.
The effect of dentist gender on the anxiety level of visiting children

Anxiety and fear of dentistry are some of the common topics among most children. The purpose of this study is to survey the effect of therapist gender on the anxiety of children. Due to considerable hypotheses and questions in this study, the t-dependent method is used to reach results. Zung questionnaire was used for the assessment of children's anxiety to 8 years old age, which was included 20 questions that considered a physical and mental condition of anxiety, which is based on the spectrum scales of not being, low, medium, and high. The statistical community consisted of 60 people obtained through a random selection of samples. The results arising from this study showed that children have more cooperation and calmness with female therapists, and their anxiety is less than the children who were treated by male therapists. Keywords: Children anxiety, therapist, gender, visiting children, dentistry
Temperature fields produced by traveling distributed heat sources

The solution of a traveling distributed heat source on a semi-infinite plate provides information about both the size and the shape of arc weld pools. The results indicate that both welding process variables (current, arc length and travel speed) and material parameters (thermal diffusivity) have significant effects on weld shape. The theoretical predictions are compared with experimental results on carbon steels, stainless steel, titanium and aluminum with good agreement. 25 references, 23 figures, 1 table.
Promoting Fruit and Vegetable Consumption for Childhood Obesity Prevention

Currently, food marketing for unhealthy foods is omnipresent. Foods high in fat, salt, and sugar (HFSS) are advertised intensively on several media platforms, including digital platforms that are increasingly used by children, such as social media, and can be bought almost everywhere. This could contribute to the obesity epidemic that we are facing. As the majority of children and adolescents do not eat the recommended amount of fruits and vegetables (F&V), which leads to chronic diseases, we need to change the obesogenic environment to a healthogenic environment. Reducing the marketing of energy-dense snacks to children and increasing the promotion of healthier foods, such as fruits and vegetables, may be an effective and necessary instrument to improve the dietary intake of children and reduce the risk of their experiencing some chronic diseases later in life. With this focused narrative review, we provide an overview of how children and adolescents react to food promotions and how food promotional efforts might be a useful tool to increase the attractiveness of fruit and vegetables. This review therefore contributes to the question of how changing the advertising and media environment of children and adolescents could help create a world where the healthy choice is the easier choice, which would reduce childhood obesity and improve children’s health, as well as to make the food system more sustainable.
