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

Diagnostic Cytopathology, EarlyView.
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%.

Diagnostic Performance of Comprehensive Point‐of‐Care Ultrasound for Pediatric Tuberculosis in Spain: A Prospective Observational Study

Journal of Clinical Ultrasound, EarlyView.
In children with presumptive tuberculosis, comprehensive point‐of‐care (cPOCUS) identified key thoracic abnormalities with high specificity and excellent inter‐reader reliability. Although diagnostic sensitivity was modest and examinations often incomplete, cPOCUS shows promise as a complementary, radiation‐free imaging tool.

In Vitro Evaluation of Novel Calcium Silicate‐Based and Resin‐Modified Calcium Silicate Materials: Cytocompatibility and Mineralization Potential on Human Dental Pulp Stem Cells for Pulp Repair

Microscopy Research and Technique, EarlyView.
This study demonstrates that Biodentine XP exhibits superior cytocompatibility, promotes odontogenic differentiation, and enhances mineralization in human dental pulp stem cells, supporting its use in regenerative endodontics. Resin‐modified materials showed lower bioactivity, highlighting the importance of material composition in pulp therapy outcomes.

Triacylglycerol‐Based Insulin Resistance Indices and Post‐Transplantation Diabetes Mellitus After Liver Transplantation

Lipids, EarlyView.
ABSTRACT Background: Post‐transplant diabetes mellitus (PTDM) is a common complication following liver transplant (LT) and is associated with adverse outcomes. The triacylglycerol‐glucose product (TyG) and the triacylglycerol‐to‐high‐density lipoprotein (HDL) cholesterol ratio (TAG/HDL‐c) are indices that can serve as triacylglycerol‐based proxies for ...

Modulation of the Stress Granule Component Carhsp1 Mitigates Disease‐Associated Deficits in Spinocerebellar Ataxia Type 3 Mouse Models

Movement Disorders, EarlyView.
Abstract Background Spinocerebellar ataxia type 3 (SCA3) is a polyglutamine (polyQ) neurogenerative disorder that results from CAG trinucleotide repeat expansions in the ATXN3 gene, leading to toxic protein aggregate formation and cellular pathway dysfunction.
