Objective To evaluate the impact of healthcare-associated infection(HAI)control culture construction on the hand hygiene(HH)compliance of health care workers(HCWs),and provide a basis for strengthening HAI management.Methods HCWs in a hospital in Xi'an City were selected as the research objects.On the occasion of World HH Day,a series of publicity activities on HH as well as HAI prevention and control were held.Pre-activi-ties period was April 1-30,2024.During May 1-31,2024,a series of publicity activities on HH as well as HAI prevention and control were carried out.The post-activities investigation period was June 1-30,2024.During De-cember 1-31,2024,HH compliance survey was carried out in batches in the whole hospital(including key depart-ments).HH compliance at different stages was compared.Results After a series of publicity activities on HH as well as HAI prevention and control,HCWs'HH compliance rate was improved.HH compliance rate of nursing staff increased from 70.15％to 85.11％;HH compliance rate of HCWs before contacting with patients increased from 47.83％to 78.38％;both with statistically significant difference(both P＜0.05).During December 1-31,2024,a batch survey on HH compliance of the whole hospital(including key departments)showed that the HH compliance rates of medical and nursing staff in key departments were higher than those of the whole hospital,and the differences were statistically significant(all P＜0.05).HH compliance rates before aseptic operation and after contacting with patients in key departments were both higher than those of the whole hospital,and the differences were statistically significant(all P＜0.05).Conclusion Publicity activities on HH as well as HAI prevention con-trol can improve HH compliance rate of HCWs.HAI managers should pay more attention to the general depart-ments and improve HH compliance rate of HCWs.

Clinical practice guidelines represent the best recommendations for patient care. They are developed through systematically reviewing currently available clinical evidence and weighing the relative benefits and risks of various interventions. However, clinical practice guidelines have to go through a long translation cycle from development and revision to clinical promotion and application, facing problems such as scattered distribution, high duplication rate, and low actual utilization. At present, the clinical practice guideline information platform can directly or indirectly solve the problems related to the lengthy revision cycles, decentralized dissemination and limited application of clinical practice guidelines. Therefore, this paper systematically examines different types of clinical practice guideline information platforms and investigates their corresponding challenges and emerging trends in platform design, data integration, and practical implementation, with the aim of clarifying the current status of this field and providing valuable reference for future research on clinical practice guideline information platforms.

A female patient, years of age 56, having no distinct inducement before 5 d but developed fever, coughing, and shortness of breath, presented in People′s Hospital of Zhongshan with community-acquired pneumonia on March 3rd, 2023. Influenza A virus infection was confirmed on March 11th after performing macro transcriptome sequencing with alveolar lavage fluid, and H3N8 was confirmed with influenza typing afterward, having declared dead on March 16th. This case is a patient with refractory multiple myeloma autologous stem cell transplantation and continuous chemotherapy with immune dysfunction. She has a history of chronic upper respiratory tract infection. Imaging showed a widespread distribution of plaques, solid lesions, and other pneumonia manifestations in both lungs, a severe decrease in the counts of white blood cells, platelets, neutrophils, and lymphocytes, and a significant increase in laboratory inflammation indicators. After the clinical consideration was an acute aggravation of chronic respiratory tract infection and poor effect of anti-bacterial treatment, fungal infection was considered, and antibiotic treatment was changed several times according to the condition. Still, the outcome was poor, and the disease progressed rapidly. Medical workers initiated Oseltamivir antiviral therapy immediately after the alveolar lavage fluid etiology confirmed A-H3N8 influenza. However, due to complex and varied systemic symptoms, including inflammatory storm, sepsis, acute respiratory failure, tachycardia, coagulopathy, and other extrapulmonary organ injuries, she died 19 days after signs due to severe respiratory failure and multiple organ failure.

Preeclampsia (PE) is one of the leading causes of maternal and perinatal morbidity and mortality worldwide. This disorder has profound short-term and long-term impacts on both the affected woman’s and her child’s health. Early-onset PE requiring preterm delivery (preterm PE) is of particular importance because it is associated with a higher risk of adverse pregnancy outcomes than term PE. First trimester screening model developed by the Fetal Medicine Foundation (FMF), which uses Bayes-theorem to combine maternal characteristics and medical history together with measurements of mean arterial pressure, uterine artery pulsatility index, and serum placental growth factor, has been proven to be effective and have superior screening performance to that of traditional risk factor-based approach for the prediction of PE. Identification of high risk pregnant women for preterm PE and giving aspirin prophylaxis before 16 th week of gestation would reduce the incidence of preterm PE. In Asia, although the prevalence of PE is slightly lower than the global estimation, early screening and prevention of this life-threatening condition is still crucial. The FMF Bayestheorem based screening method has been validated in a large-scale prospective Asia-wide study and revealed that the first trimester triple test achieves the highest detection rate, compared with the traditional risk factor-based approaches, and that the screening performance is comparable to the published data from the FMF in East Asian women. However, in order to achieve optimal screening performance, the key is to establish standardized methods for biomarker measurements and regular biomarker quality assessment, as each biomarker is susceptible to inaccurate measurement, thus affecting performance of screening. Furthermore, it is of great importance to emphasize that the optimal preventive effect of aspirin on preterm PE is clearly associated with good compliance to treatment. In conclusion, global implementation of an effective first trimester "screen and prevent" program for preterm PE would provide the opportunity to reduce the risk of both short-term maternal and perinatal morbidity and mortality, with the possibility of intergenerational prevention of future chronic diseases for both the mother and her offspring.
