A single-center study of 95 chronic kidney disease patients on hemodialysis found the Cy-TB skin test agreed completely with standard IGRA testing for latent tuberculosis, with an overall prevalence of 4.2%. Early dialysis phase (<6 months) was a strong predictor of positivity, suggesting a potential priority screening window, though larger confirmatory studies are needed.
New research reveals significant advances in blood-based biomarkers for Alzheimer's disease, including a pTau 217 assay showing 93% agreement with amyloid PET imaging and identification of interferon gamma as a diagnostic signal linked to genetic risk. These developments address challenges in early diagnosis and monitoring while requiring substantially less plasma than previous tests.
A first-in-human trial shows individualized neoantigen mRNA vaccines generated multi-year T cell responses in early-stage TNBC patients, with 82.9% of targeted mutations eliciting measurable immune activation not detectable before vaccination.
