Digital speech‐based markers to advance prognosis in Alzheimer's disease

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract Validated prognostic tools are essential to advance drug development and clinical care in Alzheimer's disease, particularly as the field shifts toward the prevention of cognitive decline. While progress has been made in developing blood‐based biomarkers for the early detection of amyloid pathology, amyloid positivity alone does not reliably ...

Cortical gray–white matter contrast alterations precede amyloid‐β positivity and macrostructural changes in older adults without dementia

Alzheimer's &Dementia, Volume 22, Issue 6, June 2026.
Abstract INTRODUCTION Early Alzheimer's disease (AD) involves subtle cortical changes that may precede atrophy. Magnetic resonance imaging (MRI) microstructural markers may detect earlier pathology than classical morphometry. METHODS We analyzed cross‐sectional MRI and amyloid‐β (Aβ) positron emission tomography (PET) data from 1323 non‐demented AMYPAD

Pancreatic Adenocarcinoma: Diagnosis by Ultrasound‐Guided Fine‐Needle Aspiration—Cyto‐Histological Correlation and Experience at a Multidisciplinary Tertiary Reference Center

Diagnostic Cytopathology, Volume 54, Issue 6, Page 403-416, June 2026.
ABSTRACT Background Pancreatic adenocarcinoma (PDAC) is characterized by its poor prognosis. Cytology is essential for diagnostic confirmation and ancillary studies. The endoscopic ultrasound (EUS) set a precedent, facilitating cytological sampling through fine‐needle aspiration (FNA), with a sensitivity of 93% and a specificity of 95%.
