Background
Anaphylaxis is an allergic disease with fatal respiratory or cardiovascular symptoms that require immediate emergency treatment. We aimed to understand the characteristics and frequency of emergency department (ED) visits of patients with anaphylaxis in Korea.

Methods
Between 2007 and 2013, using data from 147 ED from the National Emergency Department Information System in Korea, we retrospectively evaluated patients with a primary diagnosis of anaphylaxis.

Results
During the study, a total 23,313 patients visited the ED due to anaphylaxis. The number of patients with anaphylaxis who visited the ED increased from 3.0 per 100,000 population in 2007 to 11.6 per 100,000 population in 2013 (P<0.001). Overall, the frequency of anaphylaxis emergency department visits increased by 1.24 times each year (95% CI 1.23–1.25). The risk of visiting ED due to anaphylaxis by population-based age-specific group was highest in the 60–69 years old (OR 2.30, 95% CI 1.96–2.70). Deaths from anaphylaxis increased by 1.35 times per year (95% CI 1.13–1.62). The causes of anaphylaxis were unknown (80.8%; 95% CI 80.35–81.38), drugs (8.9%; 95% CI 8.47–9.24), food (4.1%; 95% CI 3.87–4.39), bees (3.2%; 95% CI 3.02–3.48) and arthropods (2.3%; 95% CI 2.11–2.48). In 2009, drugs were the most common cause of anaphylaxis in November (35.5%), followed by food in May (15.5%) (P<0.001). Between July and September, stings from insects were the most common causes (P<0.001). By age, food was the most common cause in children aged <6 years (7.6%, <12 months; 9.0%, 1–6 years) and drugs in those aged ≥7 years. The 7-year overall mortality rate was 0.104 case per 1,000,000 population; men accounted for 77.8% of the deaths. By region, the number of cases was the highest in metropolitan areas, Gyeonggi and Seoul; however, the number of anaphylaxis cases per 100,000 population was the highest in Jeju and Gangwon.

Conclusion
Based on ICD-10 codes, the number of ED visits due to anaphylaxis is increasing in Korea, and the incidence of anaphylaxis varies by region, season, and age.

Published: April 2022

AimLong acting injectable (LAI) antipsychotics are an alternative to oral antipsychotic (OAP) treatment and may be beneficial for patients in the early stages of schizophrenia. This study aims to provide a comprehensive review on the efficacy of first-generation and second-generation LAI antipsychotics in recent-onset, first-episode, and early psychosis patients.MethodsMEDLINE, EMBASE, PsycINFO, and Web of Science Core databases were used to search for studies that used LAIs in early psychosis patients. Studies published up to 06 Jun 2019 were included with no language restrictions applied. Inclusion criteria were a diagnosis of schizophrenia or related disorder, where patients were in their first episode or had a duration of illness ≤5 years.Results33 studies were included: 8 RCTs, 4 post-hoc analyses, 2 case reports, and 19 naturalistic studies. The majority of studies evaluated risperidone LAIs (N = 14) and paliperidone palmitate (N = 10), while the remainder investigated fluphenazine decanoate (N = 3), flupentixol decanoate (N = 2), and aripiprazole (N = 1). Two studies did not specify the LAI formulation used, and one cohort study compared the efficacy of multiple different LAI formulations.ConclusionsWhile the majority of data is based on naturalistic studies investigating risperidone LAIs or paliperidone palmitate, LAIs may be an effective treatment for early psychosis patients in terms of adherence, relapse reduction, and symptom improvements. There is still a need to conduct more high quality RCTs that investigate the efficacy of different LAI formulations in early psychosis patients.

Authors: Mashudi Dina Nurfarahin , Ahmad Norliza , Mohd Said Salmiah 
Published: April 2022

Background
Dengue fever is a mosquito-borne viral infection that is endemic in more than 100 countries and has the highest incidence among infectious diseases in Malaysia. The increase of dengue fever cases during the COVID-19 pandemic and the movement control order (MCO) highlighted the necessity to assess the dengue preventive practices among the population. Thus, this study aimed to determine the level of dengue preventive practices and its associated factors among residents in a residential area in Johor, Malaysia during the COVID-19 pandemic.

Method
A community-based cross-sectional study was conducted on 303 respondents from a Johor residential area between May and June 2021. A validated self-administered questionnaire was created using google forms and distributed to the respondents via WhatsApp. The questionnaire consisted of three sections: (i) Sociodemographic characteristics and history of dengue fever, (ii) dengue preventive practices, and (iii) six constructs of the Health Belief Model (HBM). The association between the dependent and independent variables were examined using multiple logistic regression with a significant level set at less than 0.05.

Result
About half of the respondents have a good level of dengue preventive practices. Respondents with a history of dengue fever (aOR = 2.1, 95% CI: 1.1–4.2, p = 0.033), low perceived susceptibility (aOR = 1.8, 95% CI: 1.1–3.0, p = 0.018), high self-efficacy (aOR = 1.7, 95% CI: 1.0–2.8, p = 0.045), and high cues to take action (aOR = 2.5, 95% CI: 1.5–4.2, p < 0.001) had higher odds of practicing good dengue preventive measures.

Conclusion
This study demonstrated a moderate level of dengue preventive practices during the COVID-19 pandemic. Therefore, a stronger dengue control programme is recommended by focusing on cues to take action, self-efficacy, and recruiting those with a history of dengue fever to assist health authorities in promoting good dengue preventive practices in the community.

Abstract
The phase equilibrium relationship of the Bi2O3–Fe2O3–Nd2O3 system at 973 K was established by means of X-ray diffraction. The phase diagram contains 9 single-phase regions, 5 two-phase regions, 7 three-phase regions and no ternary compounds. There are three solid solutions of Bi1.446Nd0.554O3-type, R3c-BiFeO3 and Pnma-NdFeO3. The lattice parameters of the Nd1-x

O3 compound increase with increasing Bi2O3 content, but the XRD peaks shift to lower 2θ values when x is 0–0.75. The effect of different mass percentages of two phases, NdFeO3 and Bi25FeO40, on the performance of the sample is explored. When the mass percentage of the second phase Bi25FeO40 increases, the magnetic properties of the samples decrease instead. The sample with a mass ratio of 59 % Bi25FeO40 shows the best adsorption performance. The effective bandwidths of the samples are 2.12 GHz, 2.76 GHz and 2.25 GHz when the mass percentage of the second phase is 17 wt.%, 59 wt.%, and 77 wt.%, respectively.

Published: April 2022

Abstract
Nonlinear metasurfaces with high conversion efficiencies have been vastly investigated. However, strong dynamic tunability of such devices is limited in conventional passive plasmonic and dielectric material platforms. Germanium antimony telluride (GST) is a promising phase-change chalcogenide for the reconfiguration of metamaterials due to strong nonvolatile changes of the real and imaginary parts of the refraction index through amorphous-crystalline phase change. The orderly structured GST has an even higher potential in tunable second-harmonic generation (SHG) with a non-centrosymmetric crystal structure at the crystalline phase, while the amorphous phase of GST does not exhibit bulk second-order nonlinearity. Here, we experimentally demonstrate SHG switches by actively controlling the crystalline phase of GST for a GST-based hybrid metasurface featuring a gap-surface plasmon resonance, and a quarter-wave asymmetric Fabry–Perot (F–P) cavity incorporating GST. We obtain SHG switches with modulation depths as high as ∼ 20 dB for the wavelengths at the on-state resonance. We also demonstrate the feasibility of multi-level SHG modulation by leveraging three controlled GST phases, i.e., amorphous, semi-crystalline, and crystalline, for the gap-surface plasmon hybrid device, which features stronger light–matter interaction and has higher resonant SHG efficiencies than the asymmetric F–P cavity device at respective GST phases. This research reveals that GST-based dynamic SHG switches can be potentially employed in practical applications, such as microscopy, optical communication, and photonic computing in the nonlinear regime.

Published: April 2022

Abstract
The growing interest in transition metal dichalcogenides (TMDs) has encouraged researchers to focus on their nonlinear optical properties, such as harmonic generation (HG), which has potential for fundamental science and applications. HG is a nonlinear phenomenon used to study low-dimensional physics and has applications in bioimaging, optical signal processing, and novel coherent light sources. In this review, we present the state-of-the-art advances of HG in atomically-thin TMDs and their heterostructures. Different factors affecting the HG in TMDs such as strain, electric gating, excitonic resonance, phase and edge modulation, and valley-induced HG are discussed with a particular emphasis on the HG in heterostructure van der Waals TMDs. Moreover, we discuss the enhancement of HG in TMDs by incorporating cavities and nanostructures including the bound states in the continuum with extreme Q-factor. This work provides a concise summary of recent progress in engineering HG in atomically-thin TMDs and their heterostructures and a compact reference for researchers entering the field.

Published: April 2022

BACKGROUND
Evidence regarding the safety and efficacy of anticoagulant thromboprophylaxis among pediatric patients hospitalized for coronavirus disease 2019 (COVID-19) is limited. We sought to evaluate safety, dose-finding, and preliminary efficacy of twice-daily enoxaparin as primary thromboprophylaxis among children hospitalized for symptomatic COVID-19, including primary respiratory infection and multisystem inflammatory syndrome in children (MISC).

METHODS
We performed a phase 2, multicenter, prospective, open-label, single-arm clinical trial of twice-daily enoxaparin (initial dose: 0.5mg/kg per dose; max: 60mg; target anti-Xa activity: 0.20–0.49IU/mL) as primary thromboprophylaxis for children &lt;18 years of age hospitalized for symptomatic COVID-19. Study endpoints included: cumulative incidence of International Society of Thrombosis and Haemostasis-defined clinically relevant bleeding; enoxaparin dose-requirements; and cumulative incidence of venous thromboembolism within 30-days of hospital discharge. Descriptive statistics summarized endpoint estimates that were further evaluated by participant age (±12 years) and clinical presentation.

RESULTS
Forty children were enrolled and 38 met analyses criteria. None experienced clinically relevant bleeding. Median (interquartile range) dose to achieve target anti-Xa levels was 0.5 mg/kg (0.48–0.54). Dose-requirement did not differ by age (0.5 [0.46–0.52] mg/kg for age ≥12 years versus 0.52 [0.49–0.55] mg/kg for age &lt;12 years, P = .51) but was greater for participants with MISC (0.52 [0.5–0.61] mg/kg) as compared with primary COVID-19 (0.48 [0.39–0.51] mg/kg, P = .010). Two children (5.3%) developed central-venous catheter-related venous thromboembolism. No serious adverse events were related to trial intervention.

CONCLUSIONS
Among children hospitalized for COVID-19, thromboprophylaxis with twice-daily enoxaparin appears safe and warrants further investigation to assess efficacy.
The Narrator (Author) and the Hero in T. Shevchenko’s Poem The Funeral Feast •
Authors: Filon Mykola , Shekhovtsova Tatiana 
Published: April 2022

The study deals with the images of the narrator / author and the prophet – the lyrical character in T. Shevchenko’s poem The Funeral Feast [Tryzna]. The purpose of the study is to comprehend the author’s conception and to reveal the whole range of the ways of expressing the author’s “self ”.In this poem, the lyrical subject is variable. He functions as the author proper as well as the narrating author and the lyrical “I”, sometimes getting the features of the lyrical character. At the same time, the narrator and the character have in common the motif of prophetical service, prophetical mission.The sense structure of the image of the prophet presents in Shevchenko’s poem a synthesis of traditional and original senses. Shevchenko combines the social with the philosophic and the ethical, the universal artistic with the individual ontological. A prophet is not just an artistic image but also a modus of social existence of the writer in his ambition through his works to promote God’s laws of society and personality on the earth as a continuation of life itself.Instead of abstract philosophic speculations and complete negation, the poet creates a special modus of his view of life and attitude towards people. This modus is love; however, it is not love in a simplified, trivial and commonplace meaning but in a deeper, religious-ontological comprehensive sense.The Funeral Feast appears to have the main elements of the motif-symbolic complex of romantic literature: the estrangement of the hero longing for heavenly harmony, prayerful yearning for the heaven he keeps memories of, selectness, loneliness, and orphanhood in earthly captivity, the motifs of the lost heaven, of death as rest and death as meeting. The hero is represented as a creative personality that finds itself in a tragic contradiction with the world.One of the significant semantic oppositions is that of the word and silence. In Shevchenko’s poem, this problem is considered in terms of a transition from silent act to action word. The work on The Funeral Feast actually reveals the insolvability of the contradiction between the prophet’s two guises (“the meek prophet” – “the severe prophet”), thus forming a complex dualistic image.In Shevchenko’s creative development, The Funeral Feast was an important step in comprehending the theme of the poet and his prophetic vocation, it marks a significant stage of the author’s spiritual and creative establishment. The poet in his higher mission is understood in the poem as a personality of a national and supernational, seraphic scale, which determines his role and place in society and in the world. The lyrical-epic nature of the genre made it possible to refer the self-expression of the author’s lyrical “I” to the objectification and personification of the lyrical character. The lyrical subject includes various forms of expressing the author’s consciousness, while the hero conceptualizes the perfect model of a creative personality in his / her prophetic essence.

Authors: Kovalenko I. I. , Shved A. V. , Davydenko Ye. O. 
Published: April 2022

Context. The problem of aggregating the decision table attributes values formed out of group expert assessments as the classification problem was solved in the context of structurally rough set notation. The object of study is the process of the mathematical models synthesis for structuring and managing the expert knowledge that are formed and processed under incompleteness and inaccuracy (roughness).
Objective. The goal of the work is to develop a set of mathematical models for group expert assessments structuring for classification inaccuracy problem solving.
Method. A set of mathematical models for structuring the group expert assessments based on the methods of the theory of evidence has been proposed. This techniques allow to correctly manipulate the initial data formed under vagueness, imperfection, and inconsistency (conflict). The problems of synthesis of group decisions has been examined for two cases: taking into account decision table existing data, only, and involving additional information, i.e. subjective expert assessments, in the process of the aggregation of the experts’ judgments.
Results. The outcomes gained can become a foundation for the methodology allowing to classify the groups of expert assessments with using the rough sets theory. This make it possible to form the structures modeling the relationship between the classification attributes of the evaluated objects, the values of which are formed out of the individual expert assessments and their belonging to the certain classes.
Conclusions. Models and methods of the synthesis of group decisions in context of structuring decision table data have been further developed. Three main tasks of structuring decision table data gained through the expert survey has been considered: the aggregation of expert judgments of the values of the decision attributes in the context of modeling of the relationship between the universe element and certain class; the aggregation of expert judgments of the values of the condition attributes; the synthesis of a group decision regarding the belonging of an object to a certain class, provided that the values of the condition attributes are also formed through the expert survey. The proposed techniques of structuring group expert assessments are the theoretical foundation for the synthesis of information technologies for the solution of the problems of the statistical and intellectual (classification, clustering, ranking and aggregation) data analysis in order to prepare the information and make the reasonable and effective decisions under incompleteness, uncertainty, inconsistency, inaccuracy and their possible combination

Authors: Kuzmych V. A. , Novotarskyi M. A. , Nesterenko O. B. 
Published: April 2022

Context. The Poisson equation is the one of fundamental differential equations, which used to simulate complex physical processes, such as fluid motion, heat transfer problems, electrodynamics, etc. Existing methods for solving boundary value problems based on the Poisson equation require an increase in computational time to achieve high accuracy. The proposed method allows solving the boundary value problem with significant acceleration under the condition of acceptable loss of accuracy.
Objective. The aim of our work is to develop artificial neural network architecture for solving a boundary value problem based on the Poisson equation with arbitrary Dirichlet and Neumann boundary conditions.
Method. The method of solving boundary value problems based on the Poisson equation using convolutional neural network is proposed. The network architecture, structure of input and output data are developed. In addition, the method of training dataset generation is described.
Results. The performance of the developed artificial neural network is compared with the performance of the numerical finite difference method for solving the boundary value problem. The results showed an acceleration of the computational speed in x10–700 times depending on the number of sampling nodes.
Conclusions. The proposed method significantly accelerated speed of solving a boundary value problem based on the Poisson equation in comparison with the numerical method. In addition, the developed approach to the design of neural network architecture allows to improve the proposed method to achieve higher accuracy in modeling the process of pressure distribution in areas of arbitrary size.
