Anaplastic Thyroid Cancer (ATC) is an aggressive form of cancer with poor prognosis, heavily influenced by its tumor immune microenvironment (TIME). Understanding the cellular and gene expression dynamics within the TIME is crucial for developing targeted therapies. This study analyzes the immune microenvironment of ATC and Papillary Thyroid Cancer (PTC) using single-cell RNA sequencing (scRNA-seq).

Imaging-guided percutaneous core needle biopsy (PCNB) is currently the most common technique for the investigation of potentially malignant bone lesions. It allows precise needle placement and better visual guidance, leading to improved diagnostic accuracy. Needle tract seeding (NTS) is a rare complication of biopsies in general, and its true incidence remains unknown.

Background: Esophageal cancer (ESC) is an aggressive disease which often presents at an advanced stage. Despite trimodal therapy, 40-50% patients can develop metastatic disease by 18 months. Identification of patients at risk for metastatic spread is challenging with need for improved prognostication.

The tumor microenvironment is an altered milieu that imposes multiple selective pressures leading to the survival and dissemination of aggressive and fit tumor cell subpopulations. How pre-tumoral and tumoral cells respond to changes in their microenvironment will determine the subsequent evolution of the tumor. In this study, we have subjected pre-tumoral and tumoral cells to coverslip-induced hypoxia, which recapitulates the intracellular hypoxia and extracellular acidification characteristic of the early tumor microenvironment, and we have used a combination of quantitative phase microscopy and epifluorescence to analyze diverse cellular responses to this altered environment.

Objective: Kawasaki disease (KD) is a common children's disease with unknown etiology, which easily involves coronary artery and causes serious cardiovascular sequelae. The purpose was to investigate the relationship between chitotriosidase activity and coronary artery aneurysm (CAA) and develop and validate a nomogram to predict CAA in KD patients.
Methods: A total of 338 KD patients were included in this study.
