Background: Postoperative hypothermia (POH) is a common issue in colorectal surgery patients, leading to complications. This study aimed to develop and validate a predictive model for identifying POH in colorectal surgery patients.
Methods: A retrospective analysis of 1,316 patients who underwent colorectal surgery between June 2020 and September 2022 was conducted using institutional medical records. Intraoperative core temperatures and potential influencing factors were collected, and regression analysis was used to identify risk factors for POH and create a model. The model's performance was evaluated using the receiver operating characteristic curve analysis.
Results: Intraoperative hypothermia occurred in 51.5 % of patients. Significant predictors of POH included gender, alcohol consumption, surgery duration, platelet count, and age. The constructed model included factors like fluid intake, platelets, cigarette use, alcohol consumption, surgery type, muscle relaxants, age, ABSI, and gender. The model showed good predictive performance with an area under the ROC curve of 0.981 and a Hosmer-Lemeshow test p-value of 0.676. The Youden index, sensitivity, specificity, and practical application rate were 0.602, 0.790, 0.812, and 98.81 %, respectively.
Conclusion: This study developed a predictive model for POH in colorectal surgery patients, considering individual factors and exploring underlying causes. Understanding risk factors and consequences of POH is crucial for nurses and perioperative professionals in clinical practice.

Nanoparticle-based drug delivery systems hold great promise for improving the effectiveness of anti-tumor therapies. However, their clinical translation remains hindered by several significant challenges, including intricate preparation processes, limited drug loading capacity, and concerns regarding potential toxicity. In this context, pure drug-assembled nanosystems (PDANSs) have emerged as a promising alternative, attracting extensive research interest due to their simple preparation methods, high drug loading efficiency, and suitability for large-scale industrial production.

Patients on chronic anticoagulation undergoing metabolic surgery represent an increased risk of complications, including both bleeding and thrombotic events, such as deep vein thrombosis (DVT) and pulmonary embolism (PE). The optimal perioperative management of patients who are receiving chronic anticoagulation therapy (CAT) is complex. In the colorectal surgery literature, patients on CAT have a 10% rate of peri-procedural bleeding and a 3% rate of thromboembolism.

: Metabolic and bariatric surgery (MBS) is a well-established treatment for severe obesity, yet its effects in patients with inflammatory bowel disease (IBD) are not well understood. MBS in this population presents unique challenges, including the potential for exacerbating inflammatory disease activity and causing complications such as malnutrition and medication malabsorption. This study aims to assess the long-term outcomes of MBS in IBD patients, focusing on both metabolic outcomes and its impact on the course of IBD.

: Enhanced recovery after surgery (ERAS) protocols aim to improve clinical outcomes, shorten hospital length of stay (LOS), and reduce costs through a multidisciplinary perioperative approach. Although introduced in colorectal surgery, they are less established in cardiac surgery, especially in combination with on-table extubation (OTE). This study evaluates the impact of a novel ERAS concept with OTE (RERACS) in elective aortic-valve-replacement and coronary bypass surgery.
