Objective To construct a nomogram model to predict the risk of pressure injuries(PI)in mechanically ventilated patients in the intensive care unit(ICU).Methods Clinical data of mechanically ventilated patients in the ICU of Zhongshan Hospital,Fudan University from January 1,2020 to March 15,2023 were retrospectively collected as the training set,and data from ICU of the same hospital from October 1,2023 to December 11,2023 were collected as the external validation set.Risk variables for PI were selected using LASSO regression and Cox proportional hazards model,and a nomogram model was constructed.Receiver operating characteristic(ROC)curve was plotted,and the area under the curve(AUC)was calculated to evaluate the model.Calibration curve and decision curve analysis(DCA)were used to assess the model's calibration and clinical applicability.The external validation was performed using the validation set data.Results A total of 580 mechanically ventilated patients were included in the training set,with 84 cases(14.5%)of PI.LASSO regression and Cox proportional hazards model selected 10 variables to construct the nomogram model.The ROC curve showed an AUC of 0.830 for predicting PI in mechanically ventilated patients.Calibration curve and DCA indicated good calibration and predictive performance of the model.The external validation set included 100 patients,with 12 cases of PI,and the AUC was 0.870.Calibration curve and DCA showed good model performance.Conclusions The nomogram model based on LASSO-Cox regression has good predictive performance and can be used to screen high-risk population for PI in mechanically ventilated patients.

Objective:
QL1604 is a highly selective, humanized monoclonal antibody against programmed death protein 1. We assessed the efficacy and safety of QL1604 plus chemotherapy as first-line treatment in patients with advanced cervical cancer.
Methods:
This was a multicenter, open-label, single-arm, phase II study. Patients with advanced cervical cancer and not previously treated with systemic chemotherapy were enrolled to receive QL1604 plus paclitaxel and cisplatin/carboplatin on day 1 of each 21-day cycle for up to 6 cycles, followed by QL1604 maintenance treatment.
Results:
Forty-six patients were enrolled and the median follow-up duration was 16.5 months. An 84.8% of patients had recurrent disease and 13.0% had stage IVB disease. The objective response rate (ORR) per Response Evaluation Criteria in Advanced Solid Tumors (RECIST) v1.1 was 58.7% (27/46). The immune ORR per immune RECIST was 60.9% (28/46).The median duration of response was 9.6 months (95% confidence interval [CI]=5.5–not estimable). The median progression-free survival was 8.1 months (95% CI=5.7–14.0). Fortyfive (97.8%) patients experienced treatment-related adverse events (TRAEs). The most common grade≥3 TRAEs (>30%) were neutrophil count decrease (50.0%), anemia (32.6%), and white blood cell count decrease (30.4%).
Conclusion
QL1604 plus paclitaxel-cisplatin/carboplatin showed promising antitumor activity and manageable safety profile as first-line treatment in patients with advanced cervical cancer. Programmed cell death protein 1 inhibitor plus chemotherapy may be a potential treatment option for the patient population who have contraindications or can’t tolerate bevacizumab, which needs to be further verified in phase III confirmatory study.
