Application of a flexible visitation system in critically ill patients: A randomized clinical trial.

Objective: To determine the feasibility of a flexible visitation system in the intensive care unit (ICU).

Methods: A randomized, open-label, parallel group clinical trial was conducted. All patients admitted to the ICU of the Lanzhou University Second Hospital from April to June 2022 were enrolled.

Matrix Metalloproteinase-9/Neutrophil Gelatinase-Associated Lipocalin Complex Activity in Human Glioma Samples Predicts Tumor Presence and Clinical Prognosis.

Matrix metalloproteinase-9/neutrophil gelatinase-associated lipocalin (MMP-9/NGAL) complex activity is elevated in brain tumors and may serve as a molecular marker for brain tumors. However, the relationship between MMP-9/NGAL activity in brain tumors and patient prognosis and treatment response remains unclear. Here, we compared the clinical characteristics of glioma patients with the MMP-9/NGAL activity measured in their respective tumor and urine samples.
