Objective:To analyze the nutritional status of elderly patients with colorectal cancer and its impact on postoperative infectious complications.Methods:A retrospective collection was conducted on 782 colorectal cancer patients admitted to the First Medical Center of PLA General Hospital from June 2020 to June 2022. The nutritional status of the patients was screened, and they were divided into nutritional risk group (355 cases) and control group (427 cases) based on whether they had nutritional risk. The main clinical characteristics and postoperative recovery of the two groups were compared. The predictive value of nutritional related indicators for postoperative infectious complications was also analyzed.Results:Univariate analysis showed that age, tumor invasion of intestinal wall muscle layer and decreased serum albumin were risk factors for nutritional risk in elderly patients with colorectal cancer ( P<0.05). The results of multivariate factor analysis showed that age≥75 years old was an independent risk factor for nutritional risk in elderly patients with colorectal cancer ( RR = 1.990, 95% CI 1.402 - 2.825, P<0.01). Compared with the control group, patients in the nutrition risk group had longer hospital stay and an increased incidence of postoperative complications: (13.59 ± 8.20) d vs. (11.91 ± 5.04) d, 16.34%(58/355) vs. 6.09%(26/427), there were statistical differences ( P<0.05). The results of multivariate factor analysis showed that elderly nutrition risk index<98, preoperative chemotherapy were risk factors for infectious complications in colorectal cancer patients ( RR = 2.982, 95% CI 1.818 - 4.890, P<0.01; RR = 2.759, 95% CI 1.119 - 6.799, P<0.05). Conclusions:The proportion of elderly patients with colorectal cancer who have nutritional risk is relatively high, and age is the main factor leading to nutritional risk. Nutritional risk can lead to an increase in postoperative infectious complications.

The announcement of the 9th edition of TNM staging system for thymic tumors was one of the highlights at the World Conference on Lung Cancer 2023. The revision, based on a larger and more detailed database, provides changes and confirmation from the last system. The 9th edition of TNM staging system aims to balance statistical significance and clinical feasibility. The birth of an improved TNM staging system heralds the changes that will follow in clinical practice and scientific research.

In recent years,public hesitancy to vaccinate has come to the fore and can hinder the advancement of immunization programs.It is important to increase public confidence in vaccines and to rationally and effectively promote the immunization behavior of the population.Based on behavioral economics theory,it combines the anchoring effect,loss aversion,two-systems theory,and the herd effect to explore the irrational factors and decision-making preferences behind the public's vaccination decisions,and then proposes discourse strategies for effective boosting to increase the public's confidence in vaccination.
