Objective:To study the risk factors of venous thromboembolism(VTE)and the predictive value of the improved VTE score model to identify the risk of VTE in gynecological surgery patients.Methods:From Janu-ary 1,2020 to December 31,2022,41 patients with VTE after gynecological surgery were selected as the VTE group,and a total of 164 patients with adjacent gynecological surgeries during the same period were selected as the non-VTE group with a ratio of 1 :4.Univariate and multivariate Logistic regression analysis were used to ana-lyze the risk factors of VTE after gynecological surgery,and a modified VTE risk factor rapid assessment model(referred to as the improved VTE score model)was constructed.The receiver operating characteristic(ROC)curve was used to study the predictive value for VTE for in gynecological surgery,and compared with the Caprini score model(Caprini table for short).Results:①Multivatiate Logistic regression analysis showed that there were independent risk factors for postoperative VTE in gynecology surgery(OR＞1,P＜0.05),including age≥60 years,BMI≥28 kg/m2,malignant tumors,surgery time＞3 hours,history of thrombosis,and the increased D-di-mer difference before and after surgery.②The Area under Curve(AUC)of ROC was 0.963 in the improved VTE score model with a Youden index 81.10％,sensitivity 87.80％and specificity 93.29％.The AUC of the Caprini score model was 0.888 with Youden index 63.41％,sensitivity 73.17％and specificity 90.24％.The improved VTE score model the Caprini score model identified 92.68％and 85.37％of VTE patients as high-risk or ex-tremely high-risk,respectively,but the difference was not statistically significant(P＜0.05).Conclusions:More attention should be paid to the six independent risk factors for postoperative VTE in gynecology surgery.The two score models showed a similar identified level.However,the improved VTE score model is more simple and easier to operate,has better practicality,and has certain clinical promotion value.

Objective:To explore the effect of comfort nursing intervention in hospice care for advanced cancer patients at home, and to provide reference for hospice care for advanced cancer patients at home.Methods:A randomized controlled trial was conducted. A total of 105 patients with advanced cancer who were treated in the Cancer Hospital Affiliated to Harbin Medical University from January to February 2023 were selected as the research objects. According to the random number table, they were divided into control group of 53 cases and intervention group of 52 cases. The control group received routine nursing methods, while the intervention group received comfort nursing interventions on this basis. The intervention lasted for 4 weeks. The changes in palliative care outcomes, quality of life and death anxiety were compared between the two groups before and after intervention.Results:Totally 105 cases were included, 53 cases in the control group and 52 cases in the intervention group. In the control group, there were 25 males, 28 females, aged (58.96 ± 10.71) years old; in the intervention group, there were 22 males, 30 females, aged (59.82 ± 10.53) years old. Before intervention, there was no statistically significant difference in palliative care outcomes, quality of life and cancer death anxiety scores between the two groups of patients (all P>0.05). After intervention, the total score of palliative care outcomes in the intervention group was (13.34 ± 5.88) points, significantly lower than (16.15 ± 5.72) points in the control group, with a statistically significant difference ( t = 2.48, P<0.05). The overall health status score of quality of life was (68.55 ± 9.34) points in the intervention group, higher than (63.01 ± 9.28) points in the control group ( t = 3.05, P<0.05). The total score of cancer death anxiety was (8.85 ± 2.72) points, significantly lower than (10.59 ± 3.14) points of the control group, with a statistically significant difference ( t = 3.04, P<0.05). Conclusions:The application of comfort nursing mode in home based hospice care can improve the quality of hospice care for advanced cancer patients, reduce their level of death anxiety, and is of great significance for improving the quality of life of advanced cancer patients.

Objective:To explore the chain mediating effect of self-efficacy and positive coping styles between nurses′ adversity quotient on work engagement, so as to provide a theoretical reference for nursing managers to promote work engagement.Methods:A convenience sampling method was used to select 512 nurses from four tertiary hospitals in Shaanxi Province, and a cross-sectional study was conducted on them using the general information questionnaire, Adversity Response Profile, General Self-Efficacy Scale, Simplified Coping Style Questionnaire and Utrecht Work Engagement Scale-9.Results:The total scores of nurses' adversity response profile, self-efficacy, positive coping style and work engagement were 132.00(120.00, 139.00), 27.00(23.00, 29.00), 24.00(20.00, 25.00), 27.00(25.00, 35.00) points. Nurses' work engagement was significantly positively correlated with adversity quotient, self-efficacy and positive coping styles( r values were 0.523-0.614, all P<0.01). The independent mediation of self-efficacy or positive coping styles and the chain mediation of both accounted for 23.6%,40.9% and 15.9% of the total effect respectively. Conclusions:Nurses′ adversity quotient not only directly affected work engagemnet, but also indirectly affected work engagement through self-efficacy and positive coping style. The research suggested that managers should pay attention to the improvement of nurses′ self-efficacy and positive coping style, so as to promote nurses′ work engagement.

Objective: To investigate the relationship between ultrasound derived ratio of femoral vein to femoral artery diameter and hemodynamics in patients with heart failure. Methods: This was a case-control study. A total of 61 patients with heart failure and 49 patients with non-heart failure hospitalized in the Department of Critical Care Medicine from September 2017 to September 2018 were included in this study. Doppler ultrasound was used to measure the femoral artery and vein diameter. After deep inhalation, the femoral vein diameter was measured again, and the ratio of femoral vein and artery diameter was calculated. The central venous pressure (CVP) and mean pulmonary wedge pressure (mPAWP) were also measured. Pearson correlation analysis was used to explore the correlation between the ratio of femoral vein diameter to femoral artery diameter and CVP and mPAWP, and linear regression equation was established. Results: The overall CVP and mPAWP levels were significantly higher, and the femoral vein diameter after deep inhalation was bigger in heart failure patients than in non-heart failure patients(all P<0.001). The femoral vein diameter/femoral artery diameter ratio was positively correlated with CVP (r=0.76, P<0.001), and positively correlated with mPAWP (r=0.40, P<0.001) in heart failure group. The linear regression equation established by the femoral vein/femoral artery diameter ratio and CVP in the heart failure group showed that the inner diameter of the femoral vein/the inner diameter of the femoral artery ratio≥1.3 corresponded CVP≥15.518 cmH₂O(1 cmH₂O=0.098 kPa) in heart failure patients. Conclusions In patients with heart failure, the inner diameter of the femoral vein/femoral artery ratio is positively correlated with CVP and mPAWP. The ratio of inner diameter of the femoral vein/femoral artery can be used to assess the volumetric load of patients with heart failure and to guide the clinical treatment of heart failure patients.
