Authors:   Akademia Łomżyńska, Bąkowski Michał , Lewkowicz-Grzegorczyk Katarzyna ,   Wydział Ekonomii i Finansów, Uniwersytet w Białymstoku
Published: January 2025

Purpose – This article is devoted to Poczta Polska, which is a sole‑shareholder company of the State Treasury. The research problem concerns the financial situation of the largest postal operator on the market. The aim of the article is to examine the financial condition of Poczta Polska SA in the years 2018–2022 in the context of further opportunities to operate on the market. Research method – The research consisted of two stages: preliminary analysis (outlining the general picture of the financial situation) and ratio analysis (which is an extension of the preliminary analysis). The assessment of the financial situation of Poczta Polska was based on the analysis of the balance sheet, analysis of the profit and loss account, cash flow statement, analysis of liquidity, debt, turnover and profitability ratios. The study used data included in the financial reports available on the post office’s website for the years 2018–2022. Results – The carried out analysis allowed for the assessment of the financial condition of the examined Poczta Polska SA, which is one of the oldest enterprises operating in Poland. The situation of the national operator is financially difficult and is systematically deteriorating. The continuation of unfavourable trends in the coming years may contribute to the bankruptcy of the post office, which would be difficult for the owner, i.e. the State Treasury. Originality / value / implications / recommendations – The raised issues are important and current, but they are not the area of interest for scientists. The carried out analysis and the formulated conclusions fill the gap in the literature and constitute an inspiration for further development of research on the financial and property situation of postal operators.

Published: January 2025

Efficient and rapid identification of corn mildew levels is essential for proper storage and transportation. This study utilized surface-enhanced Raman spectroscopy (SERS) to obtain Raman spectral fingerprints of moldy corn, combined with multi-class support vector machines (SVM) for rapid detection. Spectral data were preprocessed using the Savitzky-Golay smoothing method, and principal component analysis (PCA) was applied to extract the top five components. Feature peaks were identified using partial least squares discriminant analysis (PLS-DA) regression coefficients, supplemented by manual selection, resulting in eight characteristic wavenumber peaks (482, 878, 1046, 1082, 1220, 1276, 1452, and 1590 cm–¹). These features were used for clustering analysis, followed by SVM classification to distinguish mildew levels. The model achieved a 100% recognition rate, validated by cross-validation and confusion matrix analysis. The findings demonstrate that SERS combined with SVM enables precise differentiation of mildew levels, providing reliable support for Raman spectroscopy in fungal detection and grain safety monitoring.

Published: January 2025

Despite their environmental benefits and technical viability, mass timber structures adoption remains limited. As an alternative to steel and concrete in non-residential and multi-storey construction, they represent only 10.2% of buildings four or fewer storeys high, 1% of those five or six storeys high and 4% of those seven to twelve storeys high in Quebec. Based on a purposive sample of 42 interviews with various construction industry professionals in Quebec (Canada), the representation of mass timber construction was highlighted. A thematic analysis approach enabled a study of the motivations and barriers to adopting mass timber and the specific reasons behind them, and to determine whether respondents’ perceptions differ significantly depending on their main professional activity. The results corroborate existing literature while offering deeper insights into motivations and barriers, revealing new viewpoints. Respondents cited construction costs, expertise, manufacturing capacity, regulatory limits, and material specifications as the most critical barriers, while environmental impact and aesthetics of wood as key motivators. The response profile analysis suggests that private developers and general contractors should be the primary targets of measures promoting mass timber adoption. This research will aid in refining policies and strategies to encourage the widespread adoption of mass timber in construction practices.

Published: January 2025

The performance of five known ginger cultivars of eastern India, namely Gorubathan, Suruchi, Suprabha, Bhaisay and a Local collection, were studied in an eight-year-old 2.7 m × 2.7 m spaced arecanut plantation at Uttar Banga Krishi Vishwavidyalaya within the Teraiagro-ecological region of West Bengal. Plantlets of ginger were raised through single bud sprout techniques (SBT) using 5 g cut piece of rhizome with a plump bud and transplanted under an arecanut-based high density crop model along with bay leaf and citrus as component crops. Different ginger cultivars showed considerable variations with respect to their growth behavior and yield. The Local cultivar produced vigorous growth with a higher average number of tillers (5.83) per plant with maximum height (57.6 cm). However, the cultivar Suprabha proved its superiority over other cultivars with respect to rhizome yield, producing 2.45 tons from one hectare of crop model, with 11% net cropped area of ginger and possessing a higher benefit cost ratio (6.51).

Authors:   Research Institute for Early Childhood Education - Korea National University of Education, Ma Jia-Yi , Ahn Yoon-Ju , Kim Na-Young
Published: January 2025

The purpose of this study is to analyze research trends in early childhood English education and to explore future research directions. To achieve this, 221 domestic academic journal articles, published between 2000 and 2024 were analyzed through the Research Information Sharing Service(RISS) based on five criteria: period, target group, methodology, topic, and the researcher’s field of expertise. Freguency and percentages were calculated for each criterion. The findings are as follows: First, research on early childhood English education has been consistently conducted from 2000 to July 2024, with the highest number of studies published between 2009 and 2017. Second, regarding target groups, most studies focused on children, followed by educator, general material subjects, Caregiver, other subjects, and digital educational media. Third, in terms of methodology, quantitative research was the most common followed by mixed-methods research, qualitative research, literature reviews, and other approaches. Fourth, concerning topics, studies on the current status and perceptions were the most frequent, followed by research on English education assessment, teaching and learning methods, teacher competence, English acquisition and related variables, and curriculum improvement. Fifth, analysis based on the researcher’s fields of expertise showed that research on early childhood English education was conducted more frequently in the field of early childhood education than English education. An examination of research topics by academic fields revealed that studies in the field of early childhood education primarily focused on the current status and perceptions, while studies in the field of English education mainly addressed teaching and learning methods and English education assessment. It is anticipated that these results will provide foundational data for future research in this field.

Authors:   Research Institute for Early Childhood Education - Korea National University of Education, Park WonSoon , Yun Young Soon
Published: January 2025

This study was conducted by reanalyzing the results of the questionnaire used in “JeongWon Lee, Wonsoon Park, Jiwon Eom (2021) A Study on Policy Measures to Optimize the Media Use of Infants and Young Children, Korea Institute of Child Care and Education.” Through this study, the researchers analyzed the impact of parents' intention to provide smartphones and the places where infants and young children use smartphones on media use time and media overdependence. This study classified parents' intentions to provide smartphones for their young children into four categories: limited provision, child initiative, parent initiative, and overall provision groups. In addition, smartphone use by location could be divided into three categories: low use, high use, and residential use groups. Overall, young children spent more time using smartphones on weekends than on weekdays. The time spent using smartphones was generally higher in the group that provides smartphones according to parents' intention to provide smartphones, the group that parents determine the need for themselves, the cluster that children demand, and the cluster that provides smartphones in a limited manner. In terms of usage by location, the clusters were generally high usage, residential usage, and low usage. In the classification of smartphone overdependence by intention to provide, it was found that the group of child initiative group had a lower tendency to be smartphone overdependent than the limited provision group, which had less usage time than the group of child initiative group.

The effect of parents' activities to expand reading human rights picture books on young children's human rights awareness and parents' respect and implementation of children’s rights
Authors:   Research Institute for Early Childhood Education - Korea National University of Education, Yang Jin-Hee
Published: January 2025

The purpose of this study is to analyze the effect of parents' activities to expand reading human rights picture books on young children's human rights awareness and parents' respect and implementation of children's rights. The subjects of this study were 18 parents of 5-year-old infants and infants enrolled in S kindergarten located in Ch. Parents of infants who participated in this study conducted activities to expand reading of human rights picture books with their children twice a week for 8 weeks. As a result of this study, first, it was found that parents' activities to expand reading of human rights picture books had a significant effect on children's human rights awareness. Second, parents' activities to expand reading of human rights picture books showed a positive effect on parents' respect for and implementation of their children's rights. These results imply that parents' activities to expand reading of human rights picture books with their children have a positive effect on children's human rights awareness as well as their respect for and implementation of their own children's rights. This study implies that children's human rights awareness should be preceded by parents' respect for and implementation of their children's rights in that human rights awareness, which must be formed from infancy, is influenced by the family environment to which children belong, especially parents. This study suggests how important it is to cultivate parents' human rights awareness, and that human rights education that begins at home can play a key role in improving human rights awareness in society as a whole.

This study examined the trends in research on family-friendly policies targeting fathers at a time when men's participation in caregiving is increasing. By analyzing the limitations of existing research and exploring multifaceted research approaches, it aimed to establish more effective family-friendly policies. The study systematically analyzed trends in research on family-friendly policies for fathers in domestic academic journals from 2006 to 2024, focusing on research periods, methods, and themes. First, the number of research papers significantly increased from the 1st to the 4th Basic Plan of the Presidential Committee on Ageing Society and Population Policy. Second, quantitative research was the most common method, followed by literature review, qualitative research, and mixed methods. Third, studies on the current status and experiences of family-friendly policies were most prevalent, followed by domestic and international policy comparisons, the impact of family-friendly policies, and perceptions and demands for such policies. At this juncture, as research on family-friendly policies for fathers is being strengthened and expanded, analyzing these policies through multifaceted research can lead to more effective policy improvements to enhance fathers' participation in child-rearing and work-family balance.
O governo Lula já conseguiu superar o cerco antidemocrático?
Authors: Puglia Leonardo
Published: January 2025

Nenhum governo da Nova República havia iniciado em cenário tão delicado. Após vencer eleição com a menor diferença de votos da história, Lula sofreu uma tentativa de golpe menos de uma semana após tomar posse. Contou, então, com a atuação decisiva do Supremo Tribunal Federal para punir os responsáveis e pacificar a relação com as Forças Armadas. Só que o cerco antidemocrático, que marcou o início da gestão Lula, incluía também a pressão da burguesia vocalizada pela grande mídia. Em oito meses, o governo conseguiu pacificar a relação com o mercado através de resultados econômicos positivos e da habilidade do ministro da Fazenda Fernando Haddad, que atingiu consenso na aprovação da reforma tributária. Mas mesmo diante destas importantes vitórias, é possível afirmar que o cerco antidemocrático ao governo Lula foi superado? Quais perigos continuam no caminho da integração sul-americana em um cenário político desafiador e da construção de hegemonia progressista em um país ainda dividido? Este artigo propõe reflexões iniciais sobre essas questões decisivas para o futuro da democracia no Brasil.

Lula 3: a impotência do reformismo
Authors: Del Roio Marcos
Published: January 2025

Compreender a fase atual da economia política brasileira, com o governo Lula, exige rememorar como a crise capitalista de 2008, uma crise dentro da crise estrutural do capitalismo, só alcançou o Brasil em 2014. A crise econômica potencializou a ofensiva reacionária das classes dominantes, que vinha desde o segundo semestre de 2013. A eleição presidencial, vencida por estreita margem pelo Partido dos Trabalhadores (PT) pela quarta vez seguida, mesmo com muitas concessões ao capital financeiro, não teve seu resultado aceito, e uma conspiração para a derrubada da presidente Dilma Rousseff foi posta em marcha.

Adulto mayor con eritrodermia, una emergencia médica. Reporte de caso
Authors: Rodríguez-Ángel Jenny Paola , Morros-González Elly Alejandra , Vargas-Beltrán María Paula , Chavarro-Carvajal Diego Andrés
Published: January 2025

Resumen
Introducción. La eritrodermia es un síndrome inflamatorio cutáneo grave que afecta más del 90% de la superficie corporal. Sus causas más frecuentes incluyen psoriasis, antecedente de enfermedades dermatológicas y reacciones a ciertos medicamentos. Se considera una emergencia médica debido al elevado riesgo de disfunción de la barrera cutánea por la magnitud del compromiso epidérmico. Este riesgo es mayor en personas mayores, en quienes la eritrodermia puede exacerbar el deterioro funcional generando problemas nutricionales y alteraciones del estado de ánimo. Estas complicaciones están relacionadas con una mayor probabilidad de infecciones sistémicas, deshidratación y trastornos hidroelectrolíticos, condiciones que pueden ser agudas y potencialmente mortales.
Presentación del caso. Hombre de 76 años que ingresó al servicio de urgencias del Hospital Universitario San Ignacio de Bogotá (Colombia) por lesiones cutáneas pruriginosas, eritematosas, dolorosas y descamativas que aparecieron un año y medio antes en miembros inferiores y se diseminaron por todo el cuerpo ocasionando compromiso sistémico. El paciente fue hospitalizado con diagnóstico de eritrodermia secundaria a psoriasis. Se realizó biopsia cutánea cuyo resultado reportó dermatitis atópica crónica no específica. A través de una valoración geriátrica integral se estableció tratamiento centrado en controlar la progresión de la enfermedad y minimizar el riesgo de complicaciones sistémicas asociadas, con lo cual el paciente tuvo una evolución satisfactoria.
Conclusiones. Las enfermedades dermatológicas en adultos mayores tienden a ser subvaloradas debido a los cambios cutáneos asociados al envejecimiento. Sin embargo, afecciones como la eritrodermia deben ser sospechadas debido al alto riesgo de fracaso cutáneo agudo y las complicaciones asociadas. En estos pacientes es crucial implementar estrategias óptimas basadas en su funcionalidad y con un enfoque en el manejo nutricional, mental y social. La valoración geriátrica integral es fundamental para determinar los objetivos del tratamiento, garantizar una adecuada adherencia a este y mejorar la calidad de vida de los pacientes.
Manifestaciones clínicas de mutaciones en los genes COL4A1 y FGB. Reporte de caso
Authors: Restrepo-Ramirez Gerardo , Lenis-Patiño María Juliana , Acero-Portilla Paola Andrea , Hernández-Woodbine María José
Published: January 2025

Resumen
Introducción. El gen COL4A1 codifica la cadena alfa-1 del colágeno tipo IV, un componente estructural de las membranas basales. Por otro lado, el fibrinógeno es una glicoproteína compleja grande formada por tres pares de cadenas polipeptídicas que juega un papel importante en la hemostasia. Cada uno de estos componentes hacen parte de las membranas de muchos tejidos, incluidos los que se encuentran en ojos, riñones, cerebro, entre otros órganos. Una mutación en estos componentes puede llevar a que los pacientes presenten diversas manifestaciones clínicas.
Presentación del caso. Niña de 11 años que fue remitida al servicio de genética de una institución de cuarto nivel de atención de Cali (Colombia) por presentar manifestaciones neurológicas, renales y oftalmológicas progresivas. Se realizó estudio de secuenciación de exoma individual completo que evidenció dos variantes: una en el gen COL4A1 (c.2317G>A) reportada como patogénica y otra en el gen FGB (c.413C>G) reportada como probablemente patogénica según las recomendaciones del American College of Medical Genetics and Genomics.
Conclusiones. Las manifestaciones clínicas de las mutaciones en los genes COL4A1 y FGB son muy diversas, lo cual puede retrasar el diagnóstico. Si bien no existe un tratamiento puntual para los trastornos causados por estas mutaciones, la prevención de complicaciones y el manejo de los síntomas puede impactar positivamente la calidad de vida de los pacientes, por lo que la divulgación científica respecto a este tema es de gran importancia.
Relaciones fractales entre la variación del valor “b” de la relación GR de la sismicidad y la dimensión de capacidad de las estructuras asociadas (Sistema Falla Pinar) en un sector de Cuba occidental
Authors: Pazo-Arango Marcos Enrique
Published: January 2025

El área de estudio constituye un sector ubicado en la región de Cuba Occidental y está atravesado por la dislocación tectónica activa Falla Pinar. Esta estructura es descrita por muchos autores como la principal estructura sismo generadora en la porción occidental del territorio nacional y se le atribuye el sismo de mayor envergadura registrado en la región con una magnitud local de 6.1 ocurrido en el año 1880 en las inmediaciones de la localidad de San Cristóbal / Artemisa. La actividad sísmica vinculada al Sistema Falla Pinar y las estructuras asociadas al mismo, constituyen el objeto de estudio de esta investigación. Los datos geofísicos usados y la información geológica utilizada fueron validados mediante la comparación con los antecedentes presentes en el área de estudio y posteriormente analizados mediante técnicas de análisis fractal e interpretación de la variable precursora sísmica: “valor b” obtenida a partir de la ley de relación de Gutenberg y Richter. La interpretación de los criterios que ofrecen estos parámetros contribuye a la interpretación de la neotectónica de la región desde el punto de vista sísmico y propone a la vez un método para la identificación de áreas con más de un evento de deformación tectónica atendiendo a la dimensión de capacidad de las estructuras. Unos de los principales resultados alcanzados por las técnicas matemático–estadísticas antes mencionadas fue el comportamiento de la variación de la  en el espacio para la sismicidad, lo que se interpreta en un mapa base que puede ser utilizado en futuros estudios dedicados al peligro sísmico y la reducción de riesgos. El análisis de las propiedades fractales de la distribución de los epicentros, su magnitud y la longitud de los planos de ruptura (fallas), resultó ser una prueba matemática que confirma que el evento del año 1880 está asociado a la dislocación tectónica activa Falla Pinar tal y como expresan varios autores [1,2,4,12,13].
Evaluación del contenido de materia orgánica y sus efectos, por registros geofísicos en el ejemplo de pozos petroleros del sector Varadero Oeste, Cuba
Authors: Castro-Castiñeira Olga , Barcala-Alvarez Ronal
Published: January 2025

Desde finales del pasado siglo, varios investigadores han argumentado sobre la utilidad de los registros geofísicos de pozo para identificar rocas madres y cuantificar su potencial, a partir del efecto de la materia orgánica presente en las rocas sedimentarias sobre la respuesta de los registros. Las investigaciones sobre las rocas madre y los petróleos exigen la utilización de equipos de alto costo con los que Cuba no cuenta. Sin embargo, teniendo en cuenta el comportamiento de los registros geofísicos de pozos, donde son fundamentales la resistividad, porosidad y espectrometría gamma, se puede realizar una evaluación rápida de la capacidad de generación de hidrocarburos de secuencias descubiertas en pozos exploratorios. Esta evaluación puede realizarse sin elevado costo adicional, al aplicar métodos donde se combinan los registros. Es indispensable contar, además, con algunos datos de laboratorio para la calibración de los resultados. El alcance del presente trabajo responde al objetivo de definir las zonas con potencial generador y productor en las rocas del Grupo Veloz de pozos del sector Varadero Oeste, dentro de la Franja Petrolera Norte Cubana, y realizar correcciones a la porosidad por el efecto de la materia orgánica. Como resultado, se definen por primera vez en un yacimiento cubano los espesores generadores de las formaciones y unidades petrofísicas, y se realiza la corrección para la porosidad efectiva por la presencia de materia orgánica.

Authors: Rosidin Utang , Nurfurkon Ardika , Uang Dedy Pribadi
Published: January 2025

The purpose of this article is to describe the fulfillment of social work rights, analyzing the extent to which the government provides social security for social workers. This study uses a qualitative method with a normative juridical approach. The analysis in this study contributes to the fulfillment of social workers' rights in terms of social security and provides recommendations regarding social security regulations as a fulfillment of social workers' rights. The results show that three aspects must be considered in the rights of social workers to social security in Indonesia, namely (1) Fulfillment of Social Workers' Rights, (2) Anticipation of regulations against the risks of social workers, and (3) Social security for social workers in Indonesia. From these three aspects, there are several efforts made by the government in regulation that has issued Law Number 14 of 2019 concerning Social Workers, but the law only regulates the Rights and Obligations of Social Workers in Indonesia. The findings may also impact the lives of social workers, including improved financial well-being, job security, and professional satisfaction. Previous studies have not discussed the aspect of social security as a fulfillment of social workers' rights, so this research contributes to this void by paying attention to the analysis of the fulfillment of social workers' rights in terms of social security aspects.

Published: January 2025

The aims of this research is to clarify the type of multi-contract used by National Sharia Council-Indonesian Ulama Council (DSN-MUI) in its product innovation, so that the multi-contract concept used is a multi-contract concept that is in accordance with sharia rules and principles. This research is sharia economic law research that uses descriptive literature research methods. This research uses a normative juridical approach. The primary data used in this research is the DSN-MUI Fatwa which is related to the concept of hybrid contracts in the innovation of sharia banking products. Meanwhile, Secondary data sources include various sources of literature such as laws, scientific articles, books, and others. The data analysis technique used was the cumulative data analysis technique of Miles et al., namely data condensation, data presentation, and drawing conclusions. This study found that so far, the DSN-MUI has used the type of multi-contract for similar contracts (a combination of muawadhat contracts) and also non-similar contracts (a combination of muawadhat contracts and tabarru’ contracts) provided that there is a separation of agreement documents to avoid usury schemes for the use of these contract combinations and income (both margins, ujrah, and profit sharing) is obtained from the use of muawadhat contracts. This non-similar contract combination scheme is confirmed in the Fatwa on the Income of Islamic Financial Institutions (LKS) During the Construction Period (Fatwa No. 142 of 2021), namely Al- Uqud al-Murakkabah al-Muta’addidah. Meanwhile, the hybrid contracts scheme for similar contracts uses the Al-Uqud al-Murakkabah al-Mutajanisah hybrid contracts scheme

A liderança pode ser considerada um recurso organizacional capaz de contribuir para o engajamento dos trabalhadores e, por consequência, a autoeficácia criativa e a intenção de rotatividade podem sofrer influência desta relação. Desta forma, o objetivo desta pesquisa é analisar a importância da liderança no engajamento no trabalho e seus efeitos na autoeficácia criativa e na  intenção de rotatividade entre os servidores públicos estaduais lotados em  uma Instituição Pública no estado do Pará. Destarte, o estudo classifica-se como exploratório e descritivo, com amostragem não probabilística por julgamento, por meio de survey com 252 questionários. A coleta de dados foi on-line, e o tratamento de dados utilizou modelagem de equações estruturais (PLS-SEM). Os resultados confirmaram a influência da liderança como  recurso organizacional para manter o engajamento dos trabalhadores e também foi confirmada a relação de efeito entre engajamento, autoeficácia e  intenção de rotatividade. As conclusões recomendam o aprimoramento de políticas de gestão de pessoas para que as relações interpessoais consigam ser desenvolvidas para além do respeito pelas habilidades técnicas, para, assim, poderem ser fomentados maior comprometimento organizacional e melhorias no serviço público.
The Asymmetry of Access to Public Data
Authors: Sikora-Fernandez Dorota , Stawasz Danuta
Published: January 2025

Objective: This paper critically investigates the phenomenon of asymmetrical access to public data, a growing issue in our increasingly digitised society. Its objective is identify the root causes of asymmetry in access to public data and to propose solutions that would promote greater transparency and fairness, and foster citizen participation in public life.Research Design & Methods: The research section includes the analysis of the users of the Internet in the context of using government websites or applications by income group, age group, and place of residence. Then, the R-Pearson linear correlation analysis was used to examine the relationship between the mentioned variables.Findings: The study shows the presence of a digital divide within Poland, attributing its existence to several factors including income, educational attainment, residential location, and age. This divide encompasses not merely the accessibility of digital networks but extends to the competence required to effectively utilize these resources. Furthermore, the research highlights a significant correlation between one’s level of education and their proficiency in utilizing digital tools and conducting information searches on the internet.Implications/Recommendations: To reduce asymmetry in access to public data, policymakers should focus on creating open, user-friendly data portals with standard formats and detailed metadata. Engaging in public consultations can tailor accessibility to community needs, while partnerships with educational and non-profit organisations can offer training to enhance data utilisation skills. Such strategies aim to democratise data access, ensuring it serves a broad and diverse audience effectively.Contribution/ Value Added: The research confirms the existence of a digital divide in Poland, and some of the factors are income level, education, place of residence, and age. The gap is not only about access to the network, but also about the ability to use it. In addition, familiarity with digital tools and the ability to search for information online are strongly related to education level. Analysing the accessibility of public data in the context of income, we note that the higher the income, the higher the percentage of people using public administration online. The analysis also shows that older citizens, despite being the group least likely to use the Internet, have seen the greatest increase in regular Internet use over the studied period, in contrast to teenagers and young adults.Article classification: research articleKeywords: public data; data asymmetry; data governanceJEL O38, O36, H4

Development of ulcerative colitis (UC) is accompanied by activation of the purinergic signaling pathway and an increased level of extracellular adenosine. Adenosine is involved in regulating the balance of pro-inflammatory T-helper type 17 (Th17) cells and immunosuppressive regulatory T-cells (Treg), Their disturbance is believed to be one of the main immune factors causing this disease. However, expression of genes encoding Treg cell and Th17 transcription factors (FOXP3 and RORγ, respectively) and genes encoding members of the CD39/CD73/A2AR signaling pathway (ENTPD1, NT5E, ADORA2A) in peripheral blood has not been studied enough. The purpose of our study was to evaluate the expression levels of ENTPD1, NT5E, ADORA2A, FOXP3 and RORγ genes in ulcerative colitis (UC). Thirty-eight patients were examined including 20 patients diagnosed with UC (15 patients on a basic therapy with 5-ASA derivatives, UC1 group); 5 patients treated with Prednisone (group UC2), and 18 apparently healthy people. Total RNA was isolated from peripheral blood leukocytes (PBLCs). The levels of gene transcripts were studied by real-time PCR technique. The ENTPD1 gene mRNA content in UC patients on a basic therapy with 5-ASA derivatives was higher than in healthy people (p = 0.0045). The levels of NT5E and ADORA2A transcripts in the PBLCs of patients in the UC1 group were higher than those of patients in the UC2 group (p = 0.0486 and p = 0.0289, respectively) and healthy individuals (p = 0.0007 and p < 0.001, respectively). The mRNA content of FOXP3 gene in PBLCs of the UC1 group of patients was higher than in conditionally healthy individuals (p = 0.0093). The level of RORγ gene expression in PBLCs of the patients from UC1 and UC2 groups was higher than in healthy individuals (p = 0.0005). Increased levels of FOXP3 and RORγ gene expression (the transcription factors of Treg and Th17 cells, respectively), were observed in PBLCs of UC patients on baseline therapy, whereas expression levels of these genes in prednisolone-treated UC patients did not differ from controls. Correlations between the expression levels of some genes under study were revealed in control persons and in the UC1 group.

Chicken egg is among the most important sources of allergens. Sensitization to them is most often manifests as food allergy (FA), and/or atopic dermatitis (AD). Immunogenic substances of a chicken egg are present in both white egg and yolk.

The purpose of our work was to compare frequency and intensity of the IgE responses to various components of a chicken egg in children, depending on their age and gender. We examined 3070 children with symptoms of food allergies and atopic dermatitis, analyzed the IgE responses to chicken white egg allergens extract (f1) and yolk allergens extract (f75), taking into account the age and gender of children. The IgE levels were determined by immunofluorescence using an automatic ImmunoCAP 250 analyzer. We found a high incidence of sensitization to chicken egg in children with FA and AD: 31.07% (n = 954) of patients had clinically significant IgE levels. The frequency of sensitization to white egg was statistically significantly higher than the frequency of sensitization to yolk: 31.04% (n = 953) and 13.13% (n = 403), respectively. The maximum prevalence of positive IgE responses to white egg and yolk and more severe sensitization were observed in children of their first year of life. A significant decrease of these indices has been detected in groups of older children. In older age groups, there was also a decrease in the number of co-sensitized patients, whereas the number of monosensitization cases to chicken egg protein was increased in groups of children of 2 to 6 years old, and then decreased in children over 6 years old. The frequency of positive IgE responses to allergen extracts of white egg and yolk did not differ significantly and had similar age dynamics in children of both sexes. Statistically significant differences between the IgE responses of boys and girls were found only in groups of children over 14 years old, especially with IgE to allergens of white egg. We have shown an extremely low frequency of monosensitization to yolk: clinically significant levels of IgE to yolk in the absence of antibodies to egg protein were found in 0.1% of patients with food allergies and atopic dermatitis. High frequency of sensitization to chicken eggs in small children suggests an extremely early contact of the patients with allergens. The immunogenic ability of white egg and yolk allergens is different. Much more pronounced IgE response was observed towards white egg. A decreasing number of positive IgE response cases to chicken egg allergens in children may be due to development of immunological tolerance to both yolk and white egg at the age of 8-10 years. However, the issue of studying the allergic response mechanisms remains open, since, despite a significant decrease in prevalence of egg allergy in older children, a number of patients still do not achieve tolerance to this food product.

Influenza vaccination contributes to the favorable course and outcome of COVID-19. The aim of our study was to study the effect of influenza and pneumococcal vaccines on the level of IgG antibodies (AT) to SARS-CoV-2 among medical personnel at the beginning of the COVID-19 pandemic. We present the data on assessment of specific immune response to the influenza virus and SARS-CoV-2 in 266 medical workers 6 months after immunization against influenza and/or pneumococcal infection (without vaccinations against COVID-19) over the 2020-2021, by comparing the results with respective characteristic in 281 employees with no history of vaccinations is presented.

We have found that the proportion of medical workers with a protective (≥ 1:40) antibody levels to influenza virus 6 months after vaccination in groups of participants reaches a protective (≥ 70%) value only in persons who received a monovaccine against pneumococcal infection (78.6%) as compared with persons vaccinated with a monovaccine against influenza (61.7%) (p < 0.001), as well as with a group of workers immunized against influenza in combination with the S. pneumoniae vaccine (68.9%) (p < 0.01). Hence, the pneumococcal vaccine is able to induce the synthesis of IgG-AT to influenza virus reaching protective values.

An analysis of the group with seropositivity to influenza virus (IgG-AT ≥ 1:10) and their comparisons with persons seroprevalent to COVID-19 showed that the proportion of seropositive individuals among medical staff vaccinated against seasonal influenza after 6 months (indicating a probable asymptomatic form of COVID-19) is increased. It comprised 65.4% (p = 0.026) in the group vaccinated with mono-flu, and 64.5% (p = 0.04) in the group vaccinated with combined influenza and pneumococcus, being higher than among the non-immunized workers (48.8%).

In summary, the results of our study show that influenza vaccination acts as an inducer of humoral immunity not only to the influenza virus, but also to the recently transmitted SARS-CoV-2 infection.

ABSTRACT Objective To identify the available evidence on the risk of developing cancer in transgender people undergoing hormone therapy. Methods This was a rapid systematic review conducted in the PubMed, Embase, Virtual Health Library, Cochrane Library and Epistemonikos databases. Screening and data extraction were performed by independent reviewers using the Rayyan platform. Data extraction was carried out by 3 independent reviewers. We used the Joanna Briggs Institute checklists specific to cohort and case-control studies to assess the methodological quality of the included studies. Results Five studies were included, 4 cohort studies and 1 case-control. The risk of transgender people developing cancer while on hormone therapy was identified by 2 studies and not identified in 3 studies. Conclusion Despite studies with large sample sizes and rigorous selection criteria, the literature does not present a consensus on the association between hormone therapy and the development of cancer in transgender people.

ABSTRACT Objective To analyze the relationship between childhood abuse and self-harm in a group of transvestites and transgender women from the state of Rio de Janeiro. Methods This was a cross-sectional study conducted with 139 participants selected through convenience sampling between 2019 and 2020. A structured questionnaire was used for data collection. The odds ratio (OR) and 95% confidence intervals (95%CI) for suicidal ideation, suicide attempts, and self-harm were calculated using logistic regression. Results Having experienced emotional abuse in childhood increased the suicide attempt (OR=9.00; 95%CI 1.13;71.34), having experienced psychological violence in childhood increased self-injurious behavior (OR=11.64; 95%CI 2.35;57.5), HIV infection increased suicidal ideation (OR=2.38; 95%CI 1.09;5.21). Conclusion Childhood abuse, as well as the experience of stigmatizing diseases, increased the risk of self-harm among this population.
