Pre-processing stability of routine clinical chemistry analytes in a clotting tube; investigating the (un)suitability for at-home sample collection.

Background: There is a growing interest in self-collection of blood for clinical applications. Next to allowing patients to self-sample blood, adequate sample stability of the analyte is essential to provide an accurate and reliable test result. This is particularly important for self-collected blood, as the transport of the sample to the clinical laboratory will generally require significantly more time than routine blood samples collected by healthcare professionals, and under less controlled circumstances.

Nanoparticle display of neuraminidase elicits enhanced antibody responses and protection against influenza A virus challenge.

Current Influenza virus vaccines primarily induce antibody responses against variable epitopes in hemagglutinin (HA), necessitating frequent updates. However, antibodies against neuraminidase (NA) can also confer protection against influenza, making NA an attractive target for the development of novel vaccines. In this study, we aimed to enhance the immunogenicity of recombinant NA antigens by presenting them multivalently on a nanoparticle carrier.

Prospective multicenter evaluation of adherence to the Dutch guideline for children aged 0-16 years with fever without a source-febrile illness in children (FINCH) study.

Unlabelled: Evaluation of guidelines in actual practice is a crucial step in guideline improvement. A retrospective evaluation of the Dutch guideline for children with fever without an apparent source (FWS) showed 50% adherence in young infants. We prospectively evaluated adherence to the Dutch guideline and its impact on management in current practice.
