Summary: A study in South Korea found a decreasing trend in chronic hepatitis B cases and an increasing trend in alcoholic liver disease cases among cirrhotic patients. While the etiology of liver cirrhosis shifted, the severity of cirrhosis remained stable over a 10-year period. Additionally, the incidence of complications such as variceal bleeding, severe ascites, hepatic encephalopathy, and spontaneous bacterial peritonitis decreased significantly.

Summary: Approximately 5% of the Canadian HBV referral population is seropositive for HDV. HDV infection is closely associated with risk behaviors and both domestic and foreign-born patients with CHB. Those infected with HDV are more likely to suffer from severe liver diseases, including liver cancer, compared to HBV mono-infected patients.

Summary: This study examines the HBV characteristics and potential risk of mother-to-child transmission among HBeAg-negative/HBsAg-positive expectant mothers in an area with a high prevalence of e-CHB. It highlights the importance of considering antiviral prophylaxis eligibility in situations with limited resources and in regions where e-CHB is prevalent, as some HBeAg-negative mothers may still pose a high transmission risk.

Summary: Hepatitis A infection remains a significant global health concern, and a transition in the epidemiology of the virus has been observed in Tunisia. A study in Central-West Tunisia found a high seroprevalence of hepatitis A virus infection, with higher rates in certain age groups and rural areas. The study highlights the need for continued monitoring and potential vaccination strategies in regions with lower socioeconomic levels.

Summary: This study compared the different risk factors and impacts of hepatitis C virus-associated thrombocytopenia (HCV-TP) and hepatitis B virus-associated thrombocytopenia (HBV-TP). The findings showed that the incidence of thrombocytopenia was higher in HCV patients compared to HBV patients. Additionally, the risk factors for thrombocytopenia varied with the severity and virus type, suggesting the need for different management approaches for HCV-TP and HBV-TP.

Summary: The screening practices for hepatitis D virus (HDV) are diverse and non-standardized worldwide, leading to uncertainty in the exact prevalence of HDV. This study aimed to estimate the prevalence of HDV and investigate the trends in viral marker quantity in patients with hepatitis D in Jilin Province, China. The results showed a correlation between HDV infection and HBsAg level, anti-HDAg level, and HBV DNA level.

Summary: This study found that soluble interleukin-2 receptor (sIL-2R) is a strong laboratory marker for predicting the development of severe COVID-19 outcomes. sIL-2R levels were significantly higher in patients with severe disease compared to those with moderate disease, and the dynamic changes of sIL-2R can reflect disease severity and predict the occurrence of severe respiratory failure and mortality.

Summary: T cell receptor profiling has emerged as an important method to study COVID-19. This study proposes a novel Machine Learning approach to analyze T cell receptor repertoires, which not only explores the properties and characteristics of T cell receptors, but also identifies the preferential recognition of viral antigens by T-cell-mediated immune response. The study reveals a group of T cell receptors capable of recognizing SARS-CoV-2 antigens, which were already established in samples from the healthy cohort, suggesting a cross-reactivity phenomenon. Additionally, the study provides evidence of putative cross-reactivity between SARS-CoV-2 and a wide spectrum of pathogens and diseases.

Summary: Monitoring behavioral and cultural insights during the pandemic is important for understanding COVID-19 vaccine acceptance. Data collected through surveys showed an increase in vaccination acceptance, decrease in undecided individuals, and relatively stable vaccine resistance. Factors associated with vaccination included age, gender, following recommendations, and access to information sources. The study also identified pandemic fatigue and its impact on preventive measures. It highlighted the need for tailored approaches to hesitant populations.

Summary: West Nile virus (WNV) is an emerging neurotropic RNA virus that primarily circulates between mosquitoes and birds. In humans, most infections are asymptomatic, while a small percentage develop mild febrile infection and an even smaller percentage develop severe neuroinvasive disease. Current diagnostic tools for WNV are either serological methods with cross-reactivity or expensive molecular approaches. However, a low-cost and non-invasive synthetic biology-based method using riboswitches has been developed, which allows for sensitive detection of WNV in humans, birds, and mosquitoes.

Summary: This study investigated the bacterial communities, microbial populations, and antibiotic resistance in water and fish from different areas of Lake Karla in Greece. The results showed that Serratia fonticola and several species of Aeromonas were the dominant bacteria, with S. fonticola exhibiting resistance to multiple antibiotics. The findings suggest that Lake Karla's water can be used for irrigation and recreation, but quality management is necessary to ensure environmental hygiene and prevent zoonotic diseases.

Summary: The Asian tiger mosquito has the ability to overwinter and survive in temperate regions, which can contribute to the spread of diseases. A study in Greece shows evidence of winter survival in two different populations of the mosquito, but there are variations in lifespan between the populations. Further research is needed to understand the impact of local and climatic conditions on the survival of this mosquito species.

Summary: Since 2010, the West Nile virus (WNV) has been established in Greece. In 2022, there were 286 diagnosed cases of WNV infection in Greece, with 184 cases of neuroinvasive disease (WNND) and 33 deaths. The virus strain belonged to the Central European subclade of WNV lineage 2. Prompt diagnosis and investigation of cases are important for a timely response, and whole genome sequences enable studies on the molecular epidemiology of the disease.

Summary: COVID-19 exhibits heterogeneous clinical presentation and prognosis. In addition to old age and comorbidities, the genetic background of the host plays a crucial role in disease severity and prognosis. This study analyzes the contribution of innate immune gene polymorphisms to COVID-19 severity and identifies several polymorphisms as potential molecular predictors of clinical phenotype.
