Introduction: The coverage of pediatric pertussis vaccination in the Russian Federation is high, generally using a diphtheria, tetanus, and whole-cell pertussis vaccine in a 3-, 4.5-, and 6-month primary series and with a booster at 18 months of age. However, with no registered pertussis vaccines for adults, unvaccinated adolescents and adults can be a major source of infection of infants under 3 months of age.
Methods: A multicenter, retrospective, clinical epidemiological analysis to characterize pertussis in infants aged up to 3 months who contracted pertussis and were hospitalized in four different cities in the Russian Federation was performed. Archived medical records and a questionnaire were used to collect the relevant epidemiological and clinical aspects for each case of pertussis over a 2-year period.
Results: Infants in four different regions of the Russian Federation in the first 3 months of life, prior to their first pertussis vaccination, are at risk of pertussis infection. The severity is generally worse in neonates, and can lead to complications that can require intensive care.
Conclusion: Prior to vaccination, young infants in the Russian Federation remain vulnerable to severe pertussis, which may be worsened by their proximity to unvaccinated adults.

MicroRNA Expression in High-Grade B-Cell Lymphoma With 11q Aberration.

Mature aggressive B-cell lymphomas, such as Burkitt lymphoma (BL) and Diffuse large B-cell lymphoma (DLBCL), show variations in microRNA (miRNA) expression. The entity of High-grade B-cell lymphoma with 11q aberration (HGBCL-11q) shares several biological features with both BL and DLBCL but data on its miRNA expression profile are yet scarce. Hence, this study aims to analyze the potential differences in miRNA expression of HGBCL-11q compared to BL and DLBCL.

Relevance of the low-risk status assessment using available diagnostic tools requires a reliable confirmation. The study aimed to evaluate right ventricular perfusion and glucose metabolism using positron emission tomography (PET)/computed tomography (CT) with [13N]-ammonia and [18F]-fluorodeoxyglucose ([18F]-FDG) in 30 IPAH patients (33.

Purpose: Two previously proposed modelling approaches to explain the bimodal pattern of activity and/or sleep in are based on 1) the concept of morning and evening oscillators underlying the peaks of activity in the morning and evening, respectively, and 2) the concept of two cycles of buildup and decay of sleep pressure, gated only by the circadian oscillator. Previously, we simulated 24-h alertness-sleepiness curves in humans using a model postulating the circadian modulation of the buildup and decay phases of two (wake and sleep) homeostatic processes. Here, we tested whether a similar model could be applied to simulate the bimodal 24-h rhythm of fly locomotor activity and sleep.

Background: The Trollfjorden-Komagelva Fault Zone is the southernmost thrust fault of the Timanian Orogen and extends for thousands of kilometers from northwestern Russia to northern Norway. Though there is little about its location onshore northeastern Norway, where it is mapped as a major fault system dominantly comprised of NNE-dipping thrust faults, its continuation to the west below Caledonian nappes and offshore post-Caledonian sedimentary basins remains a matter of debate.
Methods: The present study provides a more definitive answer about the continuation of Trollfjorden-Komagelva Fault Zone west of the Varanger Peninsula by using seismic reflection, bathymetric, topographic, and magnetic data onshore Finnmark and offshore on the Finnmark Platform.
Same, same but different? A Discourse Network Analysis of the EU's framings of refugee arrivals in 2015 and 2022.

The European Union (EU) experienced two major instances of refugee influx: in 2015, refugees, mainly from Syria, Afghanistan and Iraq fled civil war, persecution, and dire conditions in neighbouring countries and in 2022, Ukrainians fled from Russia's full-scale invasion. Fusing theoretical insights on framing and crisification of migration, we ask: How do EU actors frame situations of refugee mass influx? Employing a Discourse Network Analysis, we examine EU representatives' framing of both instances with respect to three analytical foci: (1) who or what they considered to be in crisis, (2) their framing of refugees; and (3) who they saw to be responsible for solving the crisis. We show how, in 2015, EU representatives framed mass displacement predominantly as a crisis at and of Europe's borders, and refugees as threats to Member States' public, economic and cultural security.
