Background: Inflammatory myofibroblastic tumors (IMTs) are uncommon neoplasms most prevalent in individuals under 40 years old and predominantly in the lungs. Despite their rarity, multiple anaplastic lymphoma kinase (ALK)-positive IMTs, especially those of various sizes, have not been widely reported. This report describes a case of multiple ALK-positive IMTs in the lungs, aiming to further our understanding of their behavior and management.

Article Synopsis
  • - The study explores how temperature affects the plastic deformation of single crystals from quaternary and ternary medium-entropy alloys (MEAs) within the Cr-Mn-Fe-Co-Ni system, focusing on compression tests across a wide temperature range.
  • - It was found that critical resolved shear stresses (CRSSs) increase as temperatures drop, with a unique behavior below 77 K attributed to dislocation dynamics influenced by phonon interactions.
  • - The research indicates that the temperature dependence of CRSS is consistent with established theories for face-centered cubic alloys and reveals additional complexities at elevated temperatures, including solute-dislocation interactions, while providing comparisons with previous studies on high-entropy alloys.

Purpose: Surgical manipulation of the lungs increases the number of circulating tumor cells and the subsequent risk of metastasis in patients with lung cancer. This study investigated whether or not ligating the tumor-draining pulmonary vein first during lobectomy could improve the prognosis of these patients.

Methods: We retrospectively evaluated patients who underwent curative lobectomy for solitary nonsmall-cell lung carcinoma between January 2012 and December 2016.

Intravenously administered indocyanine green (ICG) accumulates in lung tumors, facilitating their detection via a fluorescence spectrum measurement. This method aids in identifying tumor locations that are invisible to the naked eye. We aim to determine the optimal ICG dose and administration method for accurate tumor identification during lung resection surgeries, utilizing a novel ICG fluorescence spectroscopy system for precise tumor localization.

Gamified interventions are an emerging approach in mental health treatment and prevention. Their positive effects on managing various clinical conditions stem from enhancing social skills. However, cost-effective options like Table-top Role-Playing Games (TTRPGs), which offer similar benefits to other game-based interventions, lack standardized methods for ensuring replicability.
