[Correlation of hematocrit and cardiovascular events in peritoneal dialysis patients].

Objective: To investigate the correlation between hematocrit (HCT) and cardiovascular events in peritoneal dialysis (PD) patients. Methods: Patients undergoing maintenance PD in the PD center of Guizhou Provincial People's Hospital from March 19, 2012 to July 9, 2020 were included. Demographic, baseline clinical and laboratory data of the patients were collected and patients were followed up until April 8, 2022. The primary endpoint was the first occurrence of a cardiovascular event. According to the tertiles of baseline HCT, the patients were divided into group Q1 (HCT≤26.6%), group Q2 (HCT>26.6%-32.4%), and group Q3 (HCT>32.4%). Laboratory indexes and cardiovascular events were compared among the three groups. Kaplan-Meier survival curve, Cox regression analysis and sensitivity analysis were used to analyze the effect of HCT on cardiovascular outcomes. Receiver operating characteristic (ROC) curve was used to analyze the predictive value of HCT for cardiovascular events in PD patients. Results: A total of 860 PD patients were included, including 494 males (57.4%) and 366 females (42.6%), with a mean age of (41.5±15.0) years. There were 287 cases in group Q1, 289 cases in group Q2, and 284 cases in group Q3, respectively. A total of 265 (30.8%) patients experienced first cardiovascular events during the follow-up period. The incidence of cardiovascular events in groups Q1, Q2 and Q3 was 36.2% (104/287), 34.3% (99/289), and 21.8% (62/284), respectively, with a statistically significant difference (P<0.001). The incidence of cardiovascular events decreased with the increase of HCT. Multivariate Cox proportional hazards regression model analysis showed that decreased HCT was a risk factor for cardiovascular events. Compared with group Q3, the risk of cardiovascular events in group Q1 increased by 50.7% (group Q2: HR=1.444, 95%CI: 1.029-2.028, P=0.034; group Q1: HR=1.570, 95%CI: 1.096-2.250, P=0.014). In the sensitivity analysis, using kidney transplantation as the competition event, the risk of cardiovascular events was lower in group Q3 than that in group Q1 (subdistributional HR=1.413, 95%CI: 1.006-1.990, P=0.046). Kaplan-Meier survival curve showed that compared with the other two groups, the cardiovascular events-free survival rate of patients in group Q1 was significantly lower (log-rank χ2=9.722, P=0.008). ROC analysis showed that the area under the curve (AUC) of HCT for predicting cardiovascular events in PD patients was 0.583 (95%CI: 0.542-0.623, P<0.001), with the sensitivity of 40.6% and the specificity of 75.1%. Conclusion: Low-level HCT is associated with an increased risk of the first cardiovascular event in PD patients.

Effect of perioperative "Internet + rehabilitation guidance" based on IKAP theory on short-term prognosis of patients with esophageal cancer.

OBJECTIVE: The aim of the study was to investigate the "Internet + rehabilitation guidance" under the theory of Information-Knowledge-Attitude-Practice (IKAP) in patients with esophageal cancer during the perioperative period and to analyze the influence on the short-term prognosis of patients with esophageal cancer. PATIENTS AND METHODS: From April 2022 to February 2023, 118 patients who underwent radical esophagectomy in the First Hospital of Huai'an Affiliated Hospital of Nanjing Medical University were enrolled using the convenience sampling method. They were divided into the IKAP group (59 cases) and the Control Group (Group C) (59 cases), according to the random number table method. The conventional intervention was performed during the perioperative period, and the IKAP group was also given "Internet + rehabilitation guidance" based on IKAP theory. The first postoperative defecation time, exhaust time, feeding time, discharge time, and postoperative complication rate of the two groups were compared. Meanwhile, blood samples were collected before surgery and 1, 3, 7, and 30 days after surgery (at outpatient review) for the detection of inflammatory factor indexes and nutritional indexes. RESULTS: Patients within the IKAP group showed a shorter first postoperative exhaust and defecation time, eating time, and hospital compared to the control group (p<0.05). Before surgery, there was no significant difference in serum inflammatory factors and nutritional indexes between the two groups (p>0.05). Comparing the levels of serum inflammatory factors in the two groups after surgery, the levels of CRP and IL-6 in the IKAP group were lower than those in the control group on days 1, 3, and 7 after surgery. After 30 days, the serum CRP level was found to be lower than the control group, but no statistical difference with the control level of serum IL-6 (p<0.05) was found. Compared with the serum nutritional index levels in the two groups: 1 d after surgery, the serum HGB, PA, and TRF levels were not different (p>0.05). The serum ALB level in the IKAP group was higher than that in the control group (p<0.05). Postoperative 3 d, 7 d, the serum levels of HGB, ALB, PA, and TRF in the IKAP group were higher than those in the control group (p<0.05). After 30 d, there was no statistical difference in serum HGB levels between the two groups (p<0.05); Serum ALB, PA, and TRF levels in the IKAP group were higher than those in the control group (p<0.05). From preoperative to 30 days after surgery, serum CRP and IL-6 levels in 2 groups were first increased and then decreased, while serum HGB, ALB, PA, and TRF levels were first decreased and then increased. After surgery, the IKAP group showed a greater incidence of complications in patients than in controls (p<0.05). CONCLUSIONS: In patients with esophageal cancer, perioperative "Internet + rehabilitation guidance" based on IKAP theory can effectively shorten the postoperative gastrointestinal function recovery time and rapidly reduce the inflammatory response, improving the nutritional status of the body, thereby reducing the risk of short-term postoperative complications.
