Enhanced Endoscopic Internal Drainage of Gastric Abscess Through Additively Manufactured Stents

Advanced Healthcare Materials, Volume 15, Issue 21, 5 June 2026.
Postoperative gastric leaks are often treated with off‐label biliary double‐pigtail stents, yet conventional extruded designs are not optimized for leak anatomy, can migrate, and may limit abscess evacuation. PETALS is introduced to optimize transmural drainage geometry and enable patient‐specific 3D‐printable stents.

Characterization and Antimicrobial Activity of Hafnium Nanostructures Fabricated by Physical Vapor Deposition Through a Colloidal Mask

Advanced Materials Interfaces, Volume 13, Issue 11, 9 June 2026.
We generate hafnium nanostructures by first depositing polystyrene particles of varying diameter followed by physical vapour deposition of hafnium thin films. The resultant structure shows a kill‐on‐contact effect against both Gram‐negative Escherichia coli and Gram‐positive Staphylococcus aureus.

Methotrexate Toxicity in a Patient With Renal Failure Despite a Normal Methotrexate Concentration: A Case Report and Literature Review

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Methotrexate (MTX) is a folate antagonist widely used as a disease‐modifying antirheumatic drug (DMARD) in rheumatoid arthritis (RA), as well as in several malignancies and autoimmune disorders. Although low‐dose MTX (5–20 mg/week) is generally considered safe, it has a narrow therapeutic index, and toxicity can occur even at therapeutic doses,
