| Shen et al., 2022 [37] | China | 32 cases | 24-hour dynamic electrocardiogram | AI-based heart rate variability (HRV) monitoring device | 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. |
IBD | Charilaou et al., 2022 [39] | United States | 398,426 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. |
