A Small‐Scale Regional External Quality Assessment of Nucleic Acid Amplification Tests for Bordetella pertussis in China

Journal of Clinical Laboratory Analysis, EarlyView.
An external quality assessment (EQA) was conducted to evaluate the performance of nucleic acid amplification tests (NAATs) for Bordetella pertussis across 69 laboratories in Chongqing, China. Among 345 total reports, 341 (98.8%) were concordant with expected results, while four false negatives occurred in low‐concentration samples near the analytical ...

Interlaboratory performance testing on EPIC v2.0 CNS tumor profiling demonstrates high reproducibility of tumor classification but reveals the need for harmonized copy number variation reporting

Brain Pathology, EarlyView.
Using the Infinium MethylationEPIC v2.0 array and Heidelberg Brain Tumor Classifier v12.8, 24 international laboratories achieved highly reproducible CNS tumor classification (97.9% correct; median β‐correlation r = 0.99), while copy number variation interpretation showed substantial interlaboratory variability, highlighting the need for harmonized CNV

Bringing Gene Therapy Into Real World Clinical Practice

Haemophilia, EarlyView.
ABSTRACT Introduction Adeno‐associated virus (AAV)‐based gene therapy for haemophilia has shifted therapeutic paradigms by enabling hepatic gene transfer, restoring endogenous clotting factor expression, and reducing reliance on conventional prophylactic treatments. Two products, valoctocogene roxaparvovec (haemophilia A) and etranacogene dezaparvovec (

UK recommendations for Ki‐67 immunohistochemical staining and interpretation in breast cancer

Histopathology, EarlyView.
Where possible, a validated digital imaging system should be utilized. If this is not available, then intermediate scores (5%–30%) should be thoroughly assessed using the Ki‐67 International Working Group guidance. Difficult cases should be double scored.
