Goal. To analyze gene expression in patients with cerebral insufficiency during the critical period and during late convalescence after severe neuroinfection. Materials and methods. The study involved patients with infectious diseases aged from 3 to 17 years, admitted for treatment to the department of resuscitation and intensive care of the Federal State Budgetary Institution DNACIB FMBA of Russia. Whole blood samples were collected before the start of therapy — «Acute period» and during the period of late convalescence after the disease (9, 12, 13 months). RNA sequencing was performed to analyze differential gene expression. Results. Statistically significant differences in expression in the comparison group «Acute period» and «Late convalescence» were detected in 14 genes. Thus, in the «Acute period» group, 12 genes with decreased expression and 2 genes with increased expression were identified: ANGPTL2, encoding angiopoietin-like protein 2 and PCK1 of the phosphoenolpyruvate carboxykinase enzyme. Of the 14 genes, 5 had unknown functions and unidentified orthologues. Conclusion. The authors suggest that increased expression of the ANGPTL2 gene may be the cause of the consequences of hypoxia, which leads to acute cerebral failure during a severe infectious process. Increased expression of PCK1 may indicate increased brain glucose demand during recovery.

The coronavirus infection is a pressing issue in modern healthcare, yet the characteristics of the SARS-CoV-2 infection course in children with comorbidities remain insufficiently studied. The aim of this study was to evaluate the clinical form, severity, and duration of SARS-CoV-2 virus shedding in pediatric patients with somatic diseases, depending on the comorbid pathology. Materials and Methods. A comprehensive single-center retrospective study was conducted, analyzing 314 medical records of patients hospitalized in the infectious diseases department of the Russian Children’s Clinical Hospital in Moscow over 11 months in 2022. The inclusion criterion was the presence of a laboratory-confirmed COVID-19 diagnosis. Results. Children with comorbidities were found to be predisposed to a more severe course of SARS-CoV-2 infection compared to the pediatric population in general. Children with hematological diseases were at the highest risk of adverse outcomes from COVID-19. Patients with oncological and hematological diseases and primary immunodeficiencies shed the SARS-CoV-2 virus significantly longer than patients with other somatic pathologies. The duration of SARS-CoV-2 RNA detection in patients with severe COVID-19 was significantly longer, which also correlated with the severity of the underlying somatic disease. Conclusion. Children with comorbidities are at risk for a more severe and prolonged course of SARS-CoV-2 infection.

The article presents current data on the state of the issue of Hepatitis A (HA) in children in the Russian Federation and describes clinical and epidemiologic features of rare cases of severe course of the disease, as well as pathogenetic mechanisms of liver damage mediated by cell immune response. Objective. To identify clinical and epidemiologic features of the modern course of HA and its outcomes in children of Saint Petersburg within the period of 2018— 2023. Materials and methods. The study included 89 children diagnosed with HA, undergoing treatment at the Children's Research and Clinical Center for Infectious Diseases from 2018 to 2023. The analysis of disease progression in this group of patients was presented using clinical-anamnestic, epidemiologic, biochemical, virologic and instrumental data. Results. The analysis of infection sources showed a high frequency of HA infection within the family (44.9 ± 0.8%) and significantly less in childcare facilities and schools (7.9 ± 1.0%). The frequency of children with unidentified sources of infection remained high (47.2 ± 0.7%). One-third of all disease cases were imported from southern regions. Most hospitalized children had icteric HA (64.0 ± 0.6%) of moderate severity (79.8 ± 0.5%). Severe HA was observed in 6 patients (6.7 ± 1.0%). During the study, 17 patients (19.1 ± 0.9%) had a prolonged, complicated course of the disease, including ascites and aplastic anemia (12.6 ± 2.2%). Ascites was found in 4 patients with severe severity and in 5 patients with moderate severity of HA. Conclusions. Currently, there is an upward trend in the incidence of HA in the Russian Federation and Saint Petersburg, especially among schoolchildren (56.2%). A rather high frequency of severe (6.7%) and complicated forms (19.1%) of the disease is observed, and the growth of ascites and aplastic anemia cases in HA draws particular attention.

Superlattice thin films of CdSe/PbSe were successfully deposited on glass substrate using successive ionic layer adsorption reaction (SILAR) method to study their properties for possible semiconductor device applications. Cadmium (II) chloride hemi (pentahydrate), lead nitrate and sodium hydrogen selenide were the precursor for Cd2+, Pb2+ and Se2- ions sources respectively. The SILAR process involved a total cycle time of 100 seconds for a complete SILAR cycle with a total of six cycles made as one layer of CdSe used as a substrate for PbSe to form CdSe/PbSe superlattice films. The deposited thin films were subjected to thermal annealing at different temperatures of 300 K, 373 K, 423 K 473 K and 523 K and characterized for their optical, structural elemental and morphological properties using UV-Vis spectroscopy, X-ray diffraction and SEM/EDS techniques. The results of the optical properties showed that absorbance is high in the VIS region while transmittance is low in the VIS region but increased to high values in the NIR region and was significantly influenced by thermal annealing. The bandgap energies of the films were found to be 1.8 eV, 1.75 eV, 1.65 eV,1.8 eV and 1.88 eV after thermal annealing at 300 K, 373 K, 423 K, 473 K and 523 K respectively. The XRD analysis showed that the deposited thin films are polycrystalline with diffraction spectra showing an increase in intensity at an annealing temperature of 523 K and preferential lattice planes of 101, 103, 203 attributed to CdSe and 100, 200, 220 attributed to PbSe films. The EDS results indicate that the films composed of Cd, Pb, Se and other elements traceable to the substrate used. The SEM results showed that the CdSe/PbSe superlattice films contained agglomeration of nanorods and rice grain-shaped nanoparticles of different sizes and shapes that were found to increase with an increase in annealing temperature. These observed properties position the films for photodetector, solar cells, light emitting diodes, photoconductors and many other electronic and optoelectronic device applications.

Critical concerns in estimating measurement invariance of the Schutte emotional intelligence scale by gender and age among undergraduate students. This research aims to analyze five research questions, which are analyzed using exploratory factor analysis together with a correlation matrix to explain the relationship between the variables studied. This study used a cross-sectional, multi-method, multi-trait research design, drawing on a random sample of 300 first-year undergraduate students selected from three universities. The Schutte Emotional Intelligence Scale, with a Cronbach's alpha coefficient of 0.872, served as the main instrument for data collection. The results showed that the Schutte Emotional Intelligence Scale demonstrated good model fit, as evidenced by the chi-square goodness-of-fit statistic (X^2(220) = 955.19, p < 0.05). This shows that the Schutte Emotional Intelligence Scale shows strong suitability with the model used in this research. However, it is important to consider that the chi-square goodness-of-fit may be affected by sample size, prompting examination of additional model fit indices. Further, within the Nigerian population, 23 out of the 33 items in the Schutte Emotional Intelligence Scale were found to be suitable for individuals in the age range of adolescence and emerging adulthood.
