Background: Double‑lumen tubes (DLTs) are commonly used for differential pulmonary ventilation during thoracic surgery. Few reports exist on subglottic stenosis among patients who underwent surgery involving DLTs; we lack immediate postoperative period documentation leading up to the onset and subsequent recovery of subglottic stenosis. Herein, we present a case of a 75-year-old woman successfully treated for subglottic stenosis after DLT.

Intradialytic hypotension and arrhythmias are complications of hemodialysis. They are associated with decreased intravascular volume due to reduced ultrafiltration volume, cardiac function, and arterial tone. The vascular endothelial glycocalyx, which exists on the surface of healthy vascular endothelial cells and maintains vascular permeability, has been suggested to be impaired by hemodialysis.

Glycocalyx is present on the surface of healthy endothelium, and the concentration of serum syndecan-1 can serve as an injury marker. This study aimed to assess endothelial injury using serum syndecan-1 as a marker of endothelial glycocalyx injury in patients who underwent hemodialysis. In this single-center, retrospective, observational study, 145 patients who underwent hemodialysis at the Gifu University Hospital between March 2017 and December 2019 were enrolled.

Article Synopsis
  • The study aimed to analyze the characteristics and outcomes of stage I lung adenocarcinoma that has tumor necrosis, examining its impact on prognosis and genetic elements.
  • Researchers reviewed 521 cases, finding that 16% had tumor necrosis, which was linked to significantly lower survival and higher recurrence rates; however, the size of necrotic areas did not affect prognosis.
  • Genetic analysis showed that tumors with necrosis had unique gene expressions related to cell cycle regulation and higher numbers of genetic mutations, especially in smokers, indicating distinct biological behavior compared to tumors without necrosis.
