Background: Phosphorylated tau (p-tau) 217 is a promising blood biomarker for Alzheimer's disease (AD). However, most p-tau217 assays have been validated solely in ethylenediaminetetraacetic acid (EDTA) plasma, leaving the clinical applicability of serum p-tau217 largely unexplored despite serum being a preferred matrix in many clinical laboratories. To address this gap, we compared p-tau217 concentrations and diagnostic performances in matched plasma and serum samples using four research-use-only assays, including three from commercial sources i.

Objectives: Our aim was to describe the epidemiology, clinical characteristics, and outcomes of staphylococcal IE in a contemporary nationwide cohort study, while comparing coagulase-negative staphylococcal IE (CoNSIE) to IE from Staphylococcus aureus (SAIE), and among IE caused by Staphylococcus epidermidis (SE), S. lugdunensis (SL), and other CoNS.
The cytokine storm associated with SARS-CoV-2 infection is one of the most distinctive pathological signatures in COVID-19 patients. Macrophages respond to this pro-inflammatory challenge by reprogramming their functional and metabolic phenotypes. Interestingly, human macrophages fail to express the inducible form of the NO synthase (NOS2) in response to pro-inflammatory activation and, therefore, NO is not synthesized by these cells.

- Streptococcus pneumoniae is a harmful bacteria that can cause serious illnesses like pneumonia, sepsis, and meningitis, with a notable serotype, 7F, involved in these diseases.
- This study focuses on how the O-acetyl group in the polysaccharide of the 7F serotype affects the body's ability to recognize the antigen and produce antibodies for protection.
- Results show that the O-acetylated polysaccharide produces a stronger immune response compared to its fully de-O-acetylated version, indicating that while the O-acetyl group isn't essential, it enhances the effectiveness of the vaccine's antigenicity and immunogenicity.
Article Synopsis
- The study investigates the genetic factors linked to severe COVID-19, specifically focusing on hospitalized cases in admixed Americans.
- Researchers conducted the largest genome-wide association study (GWAS) for COVID-19 hospitalization in this population, identifying four significant genetic associations, including two novel loci found in Latin Americans.
- The findings highlight the importance of including diverse populations in genomic research, aiming to improve understanding of genetic risks associated with COVID-19 across different ethnic groups.
