The findings provide strong evidence-based support for developing tailored and effective exercise interventions in stroke rehabilitation.

Objective:To investigate the risk factors of colorectal adenomatous polyps.Methods:The clinical data of 395 patients who underwent colonoscopy in the Tongzhou branch, Tongzhou District, Dongzhimen Hospital Affiliated to Beijing University of Chinese Medicine from August 2017 to August 2021 were analyzed. According to the examination results, adenomatous polyps were divided into adenomatous polyps group (193 cases) and non-polyp group (202 cases). The risk factors of colorectal adenomatous polyps were screened by univariate analysis and multivariate logistic regression analysis.Results:The results of single factor analysis suggested that: body mass index (BMI), sex, age, proportion of blood type A, history of large intestine polyps, history of Helicobacter pylori (Hp) infection, history of alcohol consumption, history of smoking, proportion of heavy oil diet, history of oral calcium, history of oral statins, history of oral non-steroidal anti-inflammatory drugs, history of oral antibiotics, and high fat diet (pork, beef, and animal organs), high salt diet, love of pickled food, love of sweet food, love of greasy, good mood, anxiety, depression, impatience and irritability, history of hypertension, diabetes and hyperlipidemia were statistically significant in the adenomatous polyp group and the non-polyp group (all P<0.05). Factors with P<0.05 in the above single factor analysis were taken as independent variables, and the incidence of disease was taken as dependent variable for multi-factor logistic regression analysis. The results showed that BMI, age, blood type A, Hp infection history, drinking history, smoking history, oral non-steroidal anti-inflammatory drugs history, oral antibiotics history, high salt diet, good mood, hypertension were the influencing factors for the incidence of adenomatous polyps (all P<0.05). Conclusions:High BMI, old age, blood type A, history of Hp infection, smoking history, oral non-steroidal anti-inflammatory drug history, oral antibiotics history, high salt diet and hypertension are risk factors for the development of adenomatous polyps. Drinking alcohol and good mood can reduce the risk of colorectal adenomatous polyps. Therefore, targeted intervention measures can be formulated for high-risk patients to reduce the risk of colorectal adenomatous polyps.

Objective:To investigate the risk factors associated with one-year mortality following surgery for intertrochanteric fractures in elderly patients and develop a survival prediction model.Methods:A retrospective analysis was conducted on clinical data from 532 elderly patients with intertrochanteric fractures admitted to the People's Hospital of Xinjiang Uygur Autonomous Region and the People's Hospital of Xinyang between January 2020 and September 2022.Patient demographics, laboratory indicators, and surgical variables were documented.The primary outcome assessed was the one-year mortality rate.Risk factors were identified through univariate and multivariate Cox regression analyses, leading to the development of a prognostic model.The model's predictive performance was evaluated using the Concordance Index(C-Index), time-dependent receiver operating characteristic(ROC)curve, calibration curve, and decision curve analysis(DCA).Results:Multivariate Cox regression analysis identified several key factors associated with one-year mortality after intertrochanteric fractures in elderly patients.These factors included the modified five-item frailty index( OR=1.338, 95% CI: 1.147-1.561, P<0.001), ICU admission( OR=1.694, 95% CI: 1.230-2.333, P=0.001), preoperative hemoglobin levels( OR=1.281, 95% CI: 1.016-1.616, P=0.036), surgical waiting time( OR=1.570, 95% CI: 1.063-2.319, P=0.023), and age( OR=2.196, 95% CI: 1.712-2.816, P<0.001).The prediction model showed good consistency with a C-Index of 0.769(95% CI: 0.723-0.818)in the modeling group and 0.715(95% CI: 0.612-0.750)in the validation group.Time-dependent ROC areas under the curve were 0.802(95% CI: 0.722-0.850)and 0.718(95% CI: 0.640-0.808)for the modeling and validation groups, respectively.Calibration curves for both groups indicated a good model fit, and decision curve analysis demonstrated a positive net benefit, highlighting the clinical applicability of the model. Conclusions:The modified five-item frailty index, ICU admission, preoperative hemoglobin, surgical waiting time, and age independently predict one-year mortality after surgery for intertrochanteric fractures in elderly patients.This prognostic model, utilizing these factors, shows high predictive accuracy, assisting clinicians in quick personalized assessments and setting informed expectations in clinical practice.

Objective:Surgical site infection (SSI) can markedly prolong postoperative hospital stay, aggravate the burden on patients and society, even endanger the life of patients. This study aims to investigate the national incidence of SSI following abdominal surgery and to analyze the related risk factors in order to provide reference for the control and prevention of SSI following abdominal surgery.Methods:A multicenter cross-sectional study was conducted. Clinical data of all the adult patients undergoing abdominal surgery in 68 hospitals across the country from June 1 to 30, 2020 were collected, including demographic characteristics, clinical parameters during the perioperative period, and the results of microbial culture of infected incisions. The primary outcome was the incidence of SSI within postoperative 30 days, and the secondary outcomes were ICU stay, postoperative hospital stay, cost of hospitalization and the mortality within postoperative 30-day. Multivariable logistic regression was used to analyze risk factors of SSI after abdominal surgery.Results:A total of 5560 patients undergoing abdominal surgery were included, and 163 cases (2.9%) developed SSI after surgery, including 98 cases (60.1%) with organ/space infections, 19 cases (11.7%) with deep incisional infections, and 46 cases (28.2%) with superficial incisional infections. The results from microbial culture showed that Escherichia coli was the main pathogen of SSI. Multivariate analysis revealed hypertension (OR=1.792, 95% CI: 1.194-2.687, P=0.005), small intestine as surgical site (OR=6.911, 95% CI: 1.846-25.878, P=0.004), surgical duration (OR=1.002, 95% CI: 1.001-1.003, P<0.001), and surgical incision grade (contaminated incision: OR=3.212, 95% CI: 1.495-6.903, P=0.003; Infection incision: OR=11.562, 95%CI: 3.777-35.391, P<0.001) were risk factors for SSI, while laparoscopic or robotic surgery (OR=0.564, 95%CI: 0.376-0.846, P=0.006) and increased preoperative albumin level (OR=0.920, 95%CI: 0.888-0.952, P<0.001) were protective factors for SSI. In addition, as compared to non-SSI patients, the SSI patients had significantly higher rate of ICU stay [26.4% (43/163) vs. 9.5% (514/5397), χ 2=54.999, P<0.001] and mortality within postoperative 30-day [1.84% (3/163) vs.0.01% (5/5397), χ 2=33.642, P<0.001], longer ICU stay (median: 0 vs. 0, U=518 414, P<0.001), postoperative hospital stay (median: 17 days vs. 7 days, U=656 386, P<0.001), and total duration of hospitalization (median: 25 days vs. 12 days, U=648 129, P<0.001), and higher hospitalization costs (median: 71 000 yuan vs. 39 000 yuan, U=557 966, P<0.001). Conclusions:The incidence of SSI after abdominal surgery is 2.9%. In order to reduce the incidence of postoperative SSI, hypoproteinemia should be corrected before surgery, laparoscopic or robotic surgery should be selected when feasible, and the operating time should be minimized. More attentions should be paid and nursing should be strengthened for those patients with hypertension, small bowel surgery and seriously contaminated incision during the perioperative period.
