Objective To develop a risk management system for complications associated with peripheral venous indwelling needles and to evaluate its application effect in order to reduce the risk of related complications.Methods We designed a comprehensive risk management system for peripheral intravenous indwelling needle complications,integrating specialized evidence-based guidelines with clinical practice insights,including 5 modules:intelligent assessment and decision support,intelligent inspection reminders,educational modules,collaborative case management procedures,and a knowledge base.Patients admitted to the neurology and internal classification metabolism departments of a tertiary hospital in Jilin Province were conveniently selected as the research subjects.Patients were assigned to a control group(from May to July 2022,before the implementation of the system)and an experimental group(from September to December 2022,after the implementation of the system).The incidence of complications,duration of indwelling needle,compliance rate of core indicators for nursing quality and number of nursing consultations were compared between the groups.Additionally,a self-administered questionnaire was used to assess clinical nurses'evaluations of the system.Results A total of 189 patients were included in the experimental group and 177 patients in the control group.The incidence of complications associated with peripheral intravenous indwelling needles was lower than that in the control group.The duration of indwelling peripheral intravenous needles was longer than that in the control group.The quality compliance rate of peripheral venous indwelling needle care in the experimental group was higher than that in the control group,and the number of consultation cases in the experimental group was higher than that in the control group.Comparisons between the 2 groups showed statistically significant differences for all indicators(P＜0.05).The nurses'recognition rates for the system's user-friendliness,professional guidance,and patient benefit were 77.78％,81.74％,and 82.13％,respectively.Conclusion The application of a peripheral vein indwelling needle complication risk management system can reduce the incidence of complications,prolong the duration of indwelling,and improve nursing quality.Nurses have a high recognition of this system.

Objective:To systematically evaluate the prevalence of dysphagia after treatment in patients with head and neck cancer.Methods:The Wanfang, CNKI, Web of Science, Embase, and PubMed databases were searched from their inception to May 2025. Two researchers independently performed literature screening, data extraction, and risk of bias assessment. The pooled prevalence and 95% confidence interval (CI) were used as effect measures, with heterogeneity assessed using the I2 statistics. Sensitivity analysis was conducted by a leave-one-out approach, and publication bias was evaluated using Egger's test and funnel plots. Results:A total of 18 studies were included, comprising 2,518 patients with head and neck cancer, of whom 1,303 were diagnosed with dysphagia. The meta-analysis showed that the overall prevalence of dysphagia after treatment was 51.2% (95% CI: 42.2%-60.2%). Subgroup analysis indicated higher prevalence among males (49.8%, 95% CI: 35.6%-64.0%), Asian populations (57.7%, 95% CI: 36.8%-77.2%), tumors of the hypopharynx and larynx (45.7%, 95% CI: 39.3%-52.2%), stage Ⅲ-Ⅳ disease (46.3%, 95% CI: 34.9%-58.0%), patients receiving concurrent chemoradiotherapy (51.0%, 95% CI: 41.5%-60.4%), smokers (53.0%, 95% CI: 35.1%-70.6%), studies published in 2020 or earlier (51.9%, 95% CI: 38.3%-65.4%), high-quality studies (66.5%, 95% CI: 45.1%-84.9%), and patients with a post-treatment interval ≤6 months (60.7%, 95% CI: 41.8%-78.1%) (all P<0.001). Conclusions:The prevalence of dysphagia after treatment in patients with head and neck cancer is high, with significant variations related to gender, tumor site, disease stage, geographic region, treatment modality, smoking status, publication year, study quality, and post-treatment interval. Early screening and timely intervention are recommended to improve the quality of life of patients with head and neck cancer.

Objective:To investigate the efficacy and adverse reactions of whole-lung low-dose radiotherapy (LDRT) in patients with severe/critical coronavirus disease 2019 (COVID-19).Methods:Eight patients with severe/critical COVID-19 treated in the Jiangyin Hospital Affiliated to Nantong University from January to June 2023 who were treated with whole-lung LDRT after deteriorating or failing to improve post-medical treatment were enrolled in this single-arm phase I clinical trial. They received anterior-posterior penetrating radiation in a supine or prone position, with a total dose range from 0.5 to 1.5 Gy and a dose weight ratio of 1∶1. The oxygenation status, inflammatory markers, and imaging changes before and after radiotherapy were analyzed, and patients were followed up for acute radiation-induced adverse reactions.Results:One week after LDRT, the SaO 2/FiO 2 or PaO 2/FiO 2 indices increased in seven patients (87.5%), inflammatory markers such as C-reactive protein (CRP) and interleukin-6 (IL-6) decreased in seven patients (87.5%), and chest CT/chest radiographs revealed a significant reduction in the extent of pneumonia involvement in 5 patients (62.5%). No evident acute radiation-related adverse reactions were observed. Conclusions:Whole-lung LDRT with a dose range from 0.5 to 1.5 Gy can reduce inflammatory markers, improve clinical symptoms, and promote inflammatory absorption in patients with severe/critical COVID-19 who responded poorly to medical treatment while not inducing acute adverse reactions.

Objective: To explore the relative risks of rotavirus diarrhea after exposure to different levels of atmospheric pressure in children in Guangzhou City, so as to provide reference for improving public awareness of high atmospheric pressure exposure. Methods: The study used the China Notifiable Communicable Diseases Network System and China Meteorological Science Data Sharing Service Network to collect meteorological data and data relating to daily cases of rotavirus diarrhea in children at Guangzhou Women and Children s Medical Center from 2012 to 2020. The association between rotavirus diarrhea and atmospheric pressure was analyzed using distributed lag non linear models (DLNM). The relative risks of different sex and age sub groups exposed to different atmospheric pressures were also evaluated. Results: A total of 18 587 cases of rotavirus diarrhea were reported from 2012 to 2020, among which 11 662 cases (62.7%) were boys, and 12 582 cases (67.7%) were children aged 6 to 24 months old, which represented the highest proportion. The results of the DLNM showed that the relative risk of rotavirus diarrhea was the highest on the day of exposure to extreme high atmospheric pressure ( RR =1.50, 95% CI =1.24-1.82, P <0.05) and the effect could last for 28 days. Risk of rotavirus diarrhea was low for exposure to low pressure within 2 weeks ( P <0.05). During extremely high atmospheric pressure weather, RR was higher in girls ( RR =3.31, 95% CI =1.46-7.49， P <0.05) than that in boys ( RR =1.98, 95% CI =0.96-4.07， P >0.05). Among different age sub groups, RR was the highest in children aged 24 to 60 months after exposure to the highest level of atmospheric pressure exposure ( RR =3.36, 95% CI =1.27-8.89, P <0.05). Conclusion In Guangzhou, exposure to high pressure increases the risk of rotavirus diarrhea in children. In the future, public awareness should be raised regarding the risk after exposure to high atmospheric pressure.

Objective:To observe any effect of electroacupuncture applied to the Jialianquan points in treating post-stroke oropharyngeal dysphagia.Methods:Forty-five stroke survivors with oropharyngeal dysphagia were randomly divided into an electroacupuncture group ( n=15), a neuromuscular electrical stimulation group ( n=15) and a control group ( n=15). All groups received 30 minutes of routine swallowing function training 5 times a week for 3 weeks. The electroacupuncture group was additionally provided with 30 minutes of electroacupuncture applied to the Jialianquan (CV23) points, and the neuromuscular electrical stimulation group instead received 30 minutes of neuromuscular electrical stimulation over the bilateral submental muscles. Videofluoroscopic swallowing studies were performed before and after the 3 weeks of treatment. Standardized swallowing assessment was conducted producing functional oral intake scale ratings, modified barium swallow impairment profiles and the penetration-aspiration scale scores. Surface electromyography was also employed to evaluate submental muscle functioning through measuring the swallowing time, average EMG (AEMG) value and peak amplitude. Results:After the treatment, significant improvement was observed in all of the evaluations with both groups, but the average scores were significantly better in the electroacupuncture and neuromuscular electrical stimulation groups compared with the control group and significantly better in the electroacupuncture group than in the neuromuscular electrical stimulation group.Conclusion:Electroacupuncture at the Jialianquan point can significantly improve the swallowing of stroke survivors with oropharyngeal dysphagia. It is more effective than neuromuscular electric stimulation.

Objective:To investigate the diagnostic accuracy of serological indicators and evaluate the diagnostic value of a new established combined serological model on identifying the minimal hepatic encephalopathy (MHE) in patients with compensated cirrhosis.Methods:This prospective multicenter study enrolled 263 compensated cirrhotic patients from 23 hospitals in 15 provinces, autonomous regions and municipalities of China between October 2021 and August 2022. Clinical data and laboratory test results were collected, and the model for end-stage liver disease (MELD) score was calculated. Ammonia level was corrected to the upper limit of normal (AMM-ULN) by the baseline blood ammonia measurements/upper limit of the normal reference value. MHE was diagnosed by combined abnormal number connection test-A and abnormal digit symbol test as suggested by Guidelines on the management of hepatic encephalopathy in cirrhosis. The patients were randomly divided (7∶3) into training set ( n=185) and validation set ( n=78) based on caret package of R language. Logistic regression was used to establish a combined model of MHE diagnosis. The diagnostic performance was evaluated by the area under the curve (AUC) of receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve. The internal verification was carried out by the Bootstrap method ( n=200). AUC comparisons were achieved using the Delong test. Results:In the training set, prevalence of MHE was 37.8% (70/185). There were statistically significant differences in AMM-ULN, albumin, platelet, alkaline phosphatase, international normalized ratio, MELD score and education between non-MHE group and MHE group (all P<0.05). Multivariate Logistic regression analysis showed that AMM-ULN [odds ratio ( OR)=1.78, 95% confidence interval ( CI) 1.05-3.14, P=0.038] and MELD score ( OR=1.11, 95% CI 1.04-1.20, P=0.002) were independent risk factors for MHE, and the AUC for predicting MHE were 0.663, 0.625, respectively. Compared with the use of blood AMM-ULN and MELD score alone, the AUC of the combined model of AMM-ULN, MELD score and education exhibited better predictive performance in determining the presence of MHE was 0.755, the specificity and sensitivity was 85.2% and 55.7%, respectively. Hosmer-Lemeshow test and calibration curve showed that the model had good calibration ( P=0.733). The AUC for internal validation of the combined model for diagnosing MHE was 0.752. In the validation set, the AUC of the combined model for diagnosing MHE was 0.794, and Hosmer-Lemeshow test showed good calibration ( P=0.841). Conclusion:Use of the combined model including AMM-ULN, MELD score and education could improve the predictive efficiency of MHE among patients with compensated cirrhosis.

Patients with severe or critical coronavirus disease 2019 (COVID-19) are at high risk of death primarily due to respiratory failure caused by the cytokine storm in pulmonary tissues. The treatment response of these patients remains limited. Recently, low-dose radiation therapy (LDRT) has been clinically adopted to treat severe or critical COVID-19 patients in multiple medical centers abroad, indicating high feasibility and effectiveness. However, the mechanism and optimal radiation dose are still incompletely clear. This paper reviews the radiobiological mechanism, effectiveness, adverse reactions, and radiotherapy dose of LDRT in the treatment of severe or critical COVID-19 patients, aiming to better understand the clinical benefits and adverse reactions of LDRT.
