New pathogenic influenza virus strains are constantly emerging, posing a serious risk to both human health and economic growth. To effectively control the spread of this virus, there is an urgent need for early, rapid, sensitive, simple, and cost-effective detection technologies, as well as new and effective antiviral drugs. In this study, we have successfully achieved a significant milestone by successfully fusing the H7N9 influenza virus hemagglutinin (HA) protein with the nano-luciferase component, resulting in the development of a novel set of biosensors. This remarkable achievement marks the first instance of utilizing this biosensor technology for influenza antibody detection. Our biosensor technology also has the potential to facilitate the development of antiviral drugs targeting specific epitopes of the HA protein, providing a promising avenue for the treatment of H7N9 influenza virus infections. Furthermore, our biosensors have broad applications beyond H7N9 influenza virus detection, as they can be expanded for the detection of other pathogens and drug screening applications in the future. By providing a novel and effective solution to the detection and treatment of influenza viruses, our biosensors have the potential to revolutionize the field of infectious disease control.

Three hospitals implemented molecular point-of-care tests (POCTs) to screen patients for SARS-CoV-2 infection upon admission during the 2021/2022 influenza season, which in Belgium lasted from January to April 2022. The samples were simultaneously tested for influenza A/B. Influenza positivity at admission was examined in relation to patient characteristics and symptomatology.

Subacute thyroiditis - Is it really linked to viral infection? Retrospective hospital patient registry study.

J Clin Endocrinol Metab

Objective: Subacute thyroiditis (SAT) is a painful inflammatory disorder of the thyroid gland, which - after a phase of thyrotoxicosis - leads to transient, or less frequently permanent hypothyroidism. Apart from a strong association with specific HLA alleles, the causes are uncertain. Viral disease has been hypothesised as a trigger, with Enteroviruses, namely Echoviruses and Coxsackieviruses, showing a seasonal distribution that coincides with the incidence of SAT.

Background: We continue to struggle with the prevention and treatment of the influenza virus. The 2009 swine flu pandemic, caused by the H1N1 strain of influenza A, resulted in numerous fatalities. The threat of influenza remains a significant concern for global health, and the development of novel drugs targeting these viruses is highly desirable.

Pyroptosis plays an important role in attracting innate immune cells to eliminate infected niches. Our study focuses on how influenza A virus (IAV) infection triggers pyroptosis in respiratory epithelial cells. Here, we report that IAV infection induces pyroptosis in a human and murine airway epithelial cell line.
