Targeted liquid chromatography–tandem mass spectrometry profiling of arginine and histidine derivatives in chronic migraine: Discriminatory performance and changes after onabotulinumtoxinA therapy

Headache: The Journal of Head and Face Pain, EarlyView.
Plain Language Summary People with chronic migraine may have changes in amino‐acid metabolism, but it remains unclear which metabolic pathways are associated with the disease and early response to onabotulinumtoxinA treatment. We measured plasma amino‐acid levels in patients with chronic migraine and healthy controls and assessed changes after 1 month ...

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.

Multicenter Interlaboratory Study of Thrombin Generation Assay in Healthy Adults Using the ST Genesia Analyzer With the STG‐ThromboScreen Reagent (With and Without Thrombomodulin)

International Journal of Laboratory Hematology, EarlyView.
ABSTRACT Introduction Fully automated thrombin generation (TG) assays facilitate the transition from research to clinical application. We conducted a multicenter inter‐laboratory study using the ST Genesia analyzer to evaluate assay performance and establish reference intervals in healthy adults from Spain and Portugal.

Testing for Non‐Severe Heritable Platelet Function Disorders

International Journal of Laboratory Hematology, EarlyView.
ABSTRACT Heritable platelet function disorders (HPFD) are a diverse group of bleeding disorders characterised by a primary qualitative defect in platelet function rather than platelet number. HPFD may be broadly categorised according to the severity of bleeding, with Glanzmann thrombasthenia and Bernard Soulier syndrome classically considered severe ...

AI‐Enabled Automated Schistocyte Classification in Peripheral Blood for TMA Auxiliary Diagnosis

International Journal of Laboratory Hematology, EarlyView.
ABSTRACT Background Schistocytes are critical morphological markers for thrombotic microangiopathy (TMA) diagnosis. Manual identification is hampered by inconsistent standards and high interobserver variability, compromising accuracy. Although AI has advanced in hematology, AI‐enabled schistocyte classification remains under‐studied, creating a ...

Systematic Optimization of an SLE‐DAPTAD LC–MS/MS Workflow for Simultaneous Quantification of Low‐Abundance Vitamin D3 Metabolites in Plasma

Rapid Communications in Mass Spectrometry, Volume 40, Issue 20, 30 October 2026.
ABSTRACT Rationale Liquid chromatography–tandem mass spectrometry (LC–MS/MS) analysis of vitamin D3 metabolites is analytically challenging because these compounds are structurally similar, strongly matrix‐associated, and have poor ionization efficiency.
