Association Between Pain and Frailty in Middle-Aged and Older Patients: The Mediating Roles of Sleep and Mood.

Purpose: Pain and frailty are significantly social concerns negatively affecting physical and mental health in middle-aged and older population. This study aimed to investigate the association between pain and frailty, with a particular focus on the mediating roles of sleep and mood.

Patients And Methods: A cross-sectional study was conducted involving 244 middle-aged and older participants in local hospital.

Plasma Aβ level alterations after sleep deprivation correspond to brain structural remodeling in medical night shift workers.

The relationship between brain structure alteration and metabolic product clearance after night shift work with total sleep deprivation (SD) remains unclear. Twenty-two intensive care unit staff on regularly rotating shift work were implemented with structural and diffusion MRI under both rest wakefulness (RW) and SD conditions. Peripheral blood samples were collected for the measurement of cerebral metabolites.

Machine learning predicts lymph node metastasis of poorly differentiated-type intramucosal gastric cancer.

To construct a machine learning algorithm model of lymph node metastasis (LNM) in patients with poorly differentiated-type intramucosal gastric cancer. 1169 patients with postoperative gastric cancer were divided into a training group and a test group at a ratio of 7:3. The model for lymph node metastasis was established with python machine learning.
