Summary: Tick-borne diseases are a challenge associated with warming climate, as the expansion of tick habitats and the acceleration of tick development are influenced by climatic parameters. This study focuses on European Russia and explores the link between climatic parameters and tick-related hospital visits as well as borreliosis incidence rates. The findings suggest that regions in the southern forested areas of European Russia are expected to experience a longer tick season and an increase in borreliosis incidence rates, while the northern areas with established tick populations may not see a prolongation of the tick season.

Summary: This study investigated the presence of tick species in the Western Carpathians, Poland and examined the impact of environmental factors on tick occurrence and activity, the prevalence of vectored pathogens, and tick hosts as reservoir organisms. The results showed that only two species of ticks were found in the study area, with temperature significantly affecting tick activity and the number of Ixodes ricinus nymphs varying with altitude. The main hosts for ticks were rodents, and the ticks collected from vegetation were often infected with various pathogens.

Summary: The study utilized a recombinant reporter tick-borne encephalitis virus (TBEV) to investigate its fitness in different tick-derived cell cultures and live ticks. The reporter virus successfully replicated in tick cell lines and live ticks, but fluorescence was not observed in live ticks. The results suggest that the reporter virus can be a useful tool for studying interactions between ticks and TBEV in a tick in vitro model, but further development of reporter-tagged viruses is needed for studying TBEV in live ticks.

Summary: The study found associations between the presence of tick-borne pathogens in ticks feeding on humans and self-reported symptoms. However, due to the subjective nature of such reports and the fact that infection was determined in the ticks and not in the patient samples, further prospective studies utilizing diagnostic modalities should be performed before any clinical outcome can be causally linked to infection with tick-borne pathogens.

Summary: This study built a spatial model to predict the risk of ticks on livestock farms in Britain, taking into account variables related to tick hazard and livestock exposure. Using a random forest machine learning model, the predicted results matched observed patterns of tick distribution, with the highest risk areas being in southwest and northwest England, Wales, and west Scotland. The probability of tick presence on livestock farms is predicted to increase by 5-7% across Britain under future climate scenarios, with a greater increase at higher altitudes and latitudes, further increasing the risk of tick-borne diseases.

Summary: This study proposes an innovative method to infer the SARS-CoV-2 variants responsible for clinical cases using publicly available population-level data. The analysis of over 100,000 patients from 28 countries suggests that patients hospitalized with Omicron variant infection less often present with commonly reported symptoms compared to patients infected with pre-Omicron variants. Furthermore, patients admitted to hospital after Omicron variant emergence had lower mortality compared to patients admitted during the period when Omicron variant was responsible for only a minority of infections.

Summary: Climate change has caused significant changes in seasonal weather patterns and phenology in various species. However, there is limited empirical research on the impact of these changes on the emergence and seasonal dynamics of vector-borne diseases. Lyme borreliosis, the most common vector-borne disease in the northern hemisphere, has been increasing in incidence and geographical distribution. An analysis of long-term surveillance data from Norway shows a marked change in the timing of Lyme borreliosis cases, with the peak now occurring six weeks earlier than 25 years ago. This study highlights the potential for climate change to shape the seasonal dynamics of vector-borne diseases.

Summary: Climate changes can cause sudden changes in the epidemiological characteristics of infectious wildlife diseases, leading to outbreaks. The impact of emerging infectious diseases (EIDs) on large vertebrate populations is poorly documented, in part due to limited surveillance of remote wildlife populations. In this study, the likely impact of digital necrobacillosis on wild alpine reindeer in a national park in Norway was quantified. The outbreak of digital necrobacillosis in 2019 resulted in a decrease in summer survival rate of juveniles, but its overall impact on population dynamics was moderate.

Summary: The development of antibiotic resistance, fueled by inappropriate antibiotic usage, poses a threat to global health. Despite the fact that a majority of respiratory tract infections (RTIs) are caused by viruses, antibiotics are often prescribed empirically to treat such infections. This study aimed to determine the prevalence of antibiotic treatment and investigate factors influencing antibiotic decision-making in hospitalized adults with viral RTIs. The findings revealed a role for antimicrobial stewardship to improve antibiotic use in patients admitted for viral RTIs, even in a country with relatively low antibiotic consumption rates.

Summary: This study investigates the role of ECM remodeling and excessive fibrogenesis in severe COVID-19. The findings demonstrate that certain ECM mediators such as OPN, S100A12, and YKL-40 are closely associated with disease severity and mortality. High levels of ECM mediators during hospitalization are related to thorax pathology after 3 months. In vitro experiments also show the release of certain markers (such as growth differentiation factor 15, galectin 3, and matrix metalloproteinase 9) from macrophages and lung cell lines after exposure to inactivated SARS-CoV-2, indicating a direct link between these mediators and the causal agent of COVID-19.

Summary: The thermal regime and development of permafrost in periglacial regions have a significant impact on geomorphological processes and landscape development. In Norway, approximately 10% of unstable rock slopes may be underlain by widespread permafrost. This study assesses the variations of permafrost in selected rock walls in Norway over the past 120 years, revealing sporadic to continuous permafrost distribution along the modeled profiles. The results suggest an average increase of 0.2°C per decade in ground temperature at 20m depth since the 1980s, with higher rates of change at elevated locations within a single rock wall section.

Summary: Ground temperatures in coarse deposits like blockfields and rock glaciers are observed to be lower due to lower soil moisture content. This study used the CryoGrid model to simulate the impact of drainage on ground thermal regime and ice in blocky terrain permafrost. Simulations showed that well-drained blocky deposits have significantly lower temperatures compared to other scenarios. The findings highlight the importance of considering subsurface water-ice balance in mapping permafrost distribution in mountainous areas.

Summary: Acute gastroenteritis (AGE) has a significant impact on morbidity and mortality globally. The viral cause of diarrhoeal diseases often remains unknown due to limited diagnostic resources. Non-polio enteroviruses (NPEVs) are frequently detected in stool samples from AGE cases but their role in AGE is uncertain. This study investigated the presence and diversity of NPEVs in diarrhoeal stool samples from a birth cohort in Nepal, and found that NPEVs were most commonly detected in infants up to one year old.
