Response to Vaccines in Patients with Immune-Mediated Inflammatory Diseases: A Narrative Review
Authors: Garcillán Beatriz , Salavert Miguel , Regueiro José R. , Díaz-Castroverde Sabela
Published: February 2022

Patients with immune-mediated inflammatory diseases (IMIDs), such as rheumatoid arthritis and inflammatory bowel disease, are at increased risk of infection. International guidelines recommend vaccination to limit this risk of infection, although live attenuated vaccines are contraindicated once immunosuppressive therapy has begun. Biologic therapies used to treat IMIDs target the immune system to stop chronic pathogenic process but may also attenuate the protective immune response to vaccines. Here, we review the current knowledge regarding vaccine responses in IMID patients receiving treatment with biologic therapies, with a focus on the interleukin (IL)-12/23 inhibitors. B cell-depleting therapies, such as rituximab, strongly impair vaccines immunogenicity, and tumor necrosis factor (TNF) inhibitors and the cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) fusion protein abatacept are also associated with attenuated antibody responses, which are further diminished in patients taking concomitant immunosuppressants. On the other hand, integrin, IL-6, IL-12/23, IL-17, and B-cell activating factor (BAFF) inhibitors do not appear to affect the immune response to several vaccines evaluated. Importantly, treatment with biologic therapies in IMID patients is not associated with an increased risk of infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) or developing severe disease. However, the efficacy of SARS-CoV-2 vaccines on IMID patients may be reduced compared with healthy individuals. The impact of biologic therapies on the response to SARS-CoV-2 vaccines seems to replicate what has been described for other vaccines. SARS-CoV-2 vaccination appears to be safe and well tolerated in IMID patients. Attenuated but, in general, still protective responses to SARS-CoV-2 vaccination in the context of certain therapies warrant current recommendations for a third primary dose in IMID patients treated with immunosuppressive drugs.

Published: February 2022

In this paper, improved electrothermal models of the power diode and IGBT have been developed. The main local physical effects have been considered. The proposed models are able to deal with electrical and thermal effects. The models were confirmed by comparison with other models having similar characteristics for different circuits and different temperatures. The developed models are implemented in a traction unit to study the electrothermal performance in an electric vehicle system. The models were implemented in the Pspice circuit simulation platform using standard Pspice components and analog behavior modeling (ABM) blocks. The switching performance of the diode and the IGBT have been studied under the influence of different circuit elements in order to study and estimate the on-state and switching losses pre-required for the design of various topologies of converters and inverters. The comparison shows that these models are simple, configurable with the electrical circuit simulator software. They are better able to predict the main circuit parameters needed for power electronics design. Transient thermal responses have been demonstrated for single pulse and repetition modes. The obtained results show that our model is suitable for a fully electrothermal use of power electronic circuit simulations.

Published: February 2022

Objectives: Uncertainty about the effect of age on the success rate of laryngeal mask airway (LMA) insertion led us to conduct the present study to evaluate the success rate of LMA in airway management in different age groups. Materials and Methods: A total of 183 patients, who were admitted to Shohada hospital (Tabriz, Iran) during 2018-2019, were enrolled in this descriptive, cross-sectional, prospective study. The patients were selected through the convenience sampling method and divided into 4 age groups. After anesthesia, patients were compared in terms of duration and number of LMA insertion attempts and LMA insertion complications. The data were analyzed using SPSS20 through one-way ANOVA and the Chi-square test at P<0.05). Results: There were significant statistical differences between different age groups regarding resistance against LMA insertion (P=0.008) so that insertion was most comfortable and easy in the first attempt in the adult group compared to other groups. However, no significant statistical difference was observed between different groups in terms of the rate of air leakage (P=0.129), the duration of successful LMA insertion (P=0.119), and the number of LMA insertion attempts (P=0.091). Regarding LMA insertion complications, laryngospasm was significantly higher in the middle-age and aged group (P=0.009), and blood observation on LMA was significantly higher in the pre-school and child group (P=0.005). Conclusions: According to the results of this study, no difference was found between different groups in terms of successful LMA insertion and post LMA insertion complications.

Published: February 2022

Objectives: Due to recent advances in caring for premature neonates, premature retinopathy has become an important cause of preventable blindness and ocular disabilities. Therefore, more attention is paying to its diagnostic-therapeutic methods. Thus, the current trial assessed the efficacy of oral propranolol on the treatment of retinopathy of prematurity (ROP) in neonates. Materials and Methods: In the current trial, 58 neonates with ROP were included and the efficacy of oral propranolol (0.5 mg/kg every 8 hours) was compared with the control group. Results: In the intervention group, the stage of ROP was almost the same as the control group while 31.1% of neonates in the control group were progressed to stage 3. On the other hand, it was only 6.9% (P=0.009) in the intervention group. In patients receiving propranolol, only 2 cases required invasive therapeutic interventions whereas 9 patients required such interventions in the control group (P=0.009). The ROP improvement rate was significantly higher in the intervention group. In the control group, the overall progression to higher stages was about 48.3% while it was 13.8% for the intervention group. The mean age of neonates at the time of retinal artery completion was 91.40±22.16 and 128.08±79.89 days for the control and intervention groups, respectively (P=0.136). Conclusions: The results of this study showed that adding oral propranolol to standard therapy can reduce the rate of ROP progression to higher stages in preterm neonates with low birth weight, and the need for invasive treatments.

El presente trabajo tiene por finalidad analizar las determinaciones fundamentales existentes en la vida cotidiana y sus mediaciones con la intervención profesional. Reconociendo que el cotidiano es el ámbito de la pseudo concreción, donde predominan los aspectos fenoménicos e inmediatos de la vida social, se pretende avanzar en el reconocimiento de algunas de las formas elementales que toma en el modo de producción capitalista. Es decir, se parte del análisis de las determinaciones generales del cotidiano, para avanzar sobre sus formas particulares en el capitalismo, y cómo estás se presentan en el escenario de la intervención profesional. A partir de ello, se introduce la necesidad de superar el cotidiano, conociéndolo en sus determinaciones y procesualidad histórica, para lograr una intervención situada, que permita direccionar la práctica profesional en la consecución de un proyecto profesional crítico, basado en valores emancipatorios.

ASSESSMENT OF THE CORE-PERIPHERY EFFECTS IN THE SOCIO-ECONOMIC DEVELOPMENT OF THE REGION
Authors: Hrynchyshyn Iryna , Bas-Yurchyshyn Maryana
Published: February 2022

The article is dedicated to the evaluation of the centre and periphery effects in the socio-economic development of the region.
Goal. The purpose is to assess the core and peripheral effects of the impact on socio-economic development of the region.
Method (methodology). Methods of logical generalization, analysis, comparison and synthesis, integrated assessment, spatial autocorrelation are used to assess of the levels of core-periphery relations in the region.
Results. The core-periphery relations are a multilevel hierarchy with a representation of economic, social and spatial aspects. The core-periphery relation in the region is an evidence of a complex system of subordination where the core area causes most of the effects and directs the development. At the same time, different core areas of development may arise and influence on the periphery territory by absorbing its resources in the process of development of core-periphery relations. A methodical approach for evaluation of the core-periphery relations has been suggested. The methodical approach comprises: the identification of core-periphery relation in the region under the influence of the centre: the distinction of economic “growth points” and areas of their impact on the region (inner periphery and outer periphery); the assessment of the intensity of the centre or “growth points” impacts on the region. The analysis revealed a core and “growth points”, identified periphery areas in Lviv region, measured the influence of the cities of regional significance. The core-periphery relations in the region can be identified as multilevel hierarchy with economic, social and spatial aspects. Analyzing the core-periphery relations from this point of view we have distinguished features and types of such relations between territorial communities (core, “growth point”, and periphery). We have identified some areas with low levels of integration into the regional economic space and low level of social development. For such territorial communities, a differentiated approach should be implemented in order to boost economic growth along with the level of social development. Moreover, we have determined the spread of positive effects from the cities of regional significance to the socio-economic development of the region, as well as identified areas beyond their influence.

Authors: Nipialidi Olha
Published: February 2022

The subject of the study is the security space of the countries of the Greater Middle Eastand North Africa and its significance for Ukraine.
The aim of the article is to identify the main trends in the geopolitical transformation of the Middle East regional system and to identify conflict issues that destabilize the region and deepen instability. Taking into account these facts, Ukraine will be able to systematically extract foreign economic policy in relation to the consolidated space of the Greater Middle East and North Africa.
Methodology (method). General scientific and special methods were used in the research process in order to achieve the goal and solve the outlined tasks: historical and logical, analysis and synthesis, generalization and quantitative comparison, visual (tabular and graphical) (to visualize the results of the study).
Results. It is determined that the system of regional international relations is in the conditions of cardinal changes, which leads to their restructuring, creation of a new balance of power and formation of new relations between the states. The structural structure of the Greater Middle East and North Africa region is established and the historical preconditions of its formation are detailed. The main tendencies to the geopolitical transformation of the Middle Eastern regional system are confirmed. Projects of restructuring the political map of the Middle East and the Muslim world and possible consequences for international security are analysed. The growing role of individual countries in the study region in the global economy, which is determined by the presence of significant natural resources, including oil and gas, is confirmed. The main challenges for development and stability in the Middle East have been identified, including local conflicts, the growth of terrorist acts, and ethnic problems. Local conflicts that destabilize the region, as almost all countries have sufficient resources to confront, are analysed. It has been confirmed that the most powerful countries in the region are increasing their military potential to secure their interests.
