Nucleoside antiviral agents with atypical structures and new targets.

Nucleoside analogs (NAs), as antiviral drugs, play a significant role in clinical medicine, constituting approximately 50 % of all antiviral therapies in current use. Nucleoside inhibitors function by mimicking the structure of natural nucleosides, integrating themselves into viral genetic material during replication, and subsequently inhibiting the virus's ability to reproduce. They are used to treat a variety of viral infections, including herpes simplex, hepatitis B, and acquired immunodeficiency syndrome (AIDS).

Global impact of 10- and 13-valent pneumococcal conjugate vaccines on pneumococcal meningitis in all ages: the PSERENADE project.

Background: Pneumococcal conjugate vaccines (PCVs) introduced in childhood national immunization programs lowered vaccine-type invasive pneumococcal disease (IPD), but replacement with non-vaccine-types persisted throughout the PCV10/13 follow-up period. We assessed PCV10/13 impact on pneumococcal meningitis incidence globally.

Methods: The number of cases with serotyped pneumococci detected in cerebrospinal fluid and population denominators were obtained from surveillance sites globally.
