Postoperative decreases in TNF-α levels and VAS scores were observed in peripheral blood during the “daytime alertness, nighttime darkness” period. Postoperative time to passage of flatus/bowel movements was shortened, postoperative complication rate was reduced, and length of hospital stay was decreased.

Maintaining the “daytime alertness, nighttime darkness” status is beneficial for the postoperative recovery of gastric cancer patients.

Clinical features

Multivariable logistic regression model

Hospitalized patient mortality prediction: The QLattice model performed best with a sensitivity of 85.3%, specificity of 72.9%, and AUC of 0.867 [95% CI 0.855 - 0.879]. Performance of inpatient mortality prediction model in surgical subcohort: Sensitivity of 84.5%, specificity of 90.0%, and AUC of 0.944 [95% CI 0.932 - 0.956].

The IM-IBD calculator achieved good validation for risk stratification of inpatient mortality and prediction

in the surgical

subcohort.
