Objective To analyze the epidemiological characteristics of acute respiratory infections(ARIs)during the autumn-winter season in Beijing,providing evidence for the prevention,control,diagnosis,and treatment of ARIs.Methods A convenience sampling method was employed,enrolling patients who visited Peking Union Medical College Hospital(PUMCH)between September 2023 and February 2024 due to ARIs.Na-sopharyngeal swabs were collected,and real-time fluorescence quantitative PCR was used to detect six common respiratory pathogens[influenza A virus(FluA),influenza B virus(FluB),human rhinovirus(HRV),Myco-plasma pneumoniae(MP),respiratory syncytial virus(RSV),and adenovirus(ADV)],as well as SARS-CoV-2 infection.The distribution patterns of pathogen infections were analyzed.Results A total of 5556 eligible patients were included.The overall positivity rate for the six common respiratory pathogens was 63.7％,with sin-gle-pathogen positivity at 54.0％,dual-pathogen positivity at 8.9％,and triple or more pathogen positivity at 0.7％.The predominant pathogens detected were FluA(16.1％)and RSV(15.7％),followed by ADV(11.1％),MP(11.1％),HRV(10.0％),and FluB(10.0％).No significant difference in overall pathogen positivity was observed between genders.However,significant differences were found between autumn and winter(x2=34.617,P＜0.001)and among pediatric,young/middle-aged,and elderly patients(x2=422.38,P＜0.001).Specifically,MP(x2=8.647,P=0.003),FluA(x2=131.932,P＜0.001),and HRV(x2=174.199,P＜0.001)exhibited significantly higher positivity rates in autumn than in winter,whereas FluB was more prevalent in winter(x2=287.894,P＜0.001).In pediatric patients,MP,RSV,HRV,and ADV positivity rates were significantly higher than in young/middle-aged and elderly patients(all P＜0.001),whereas FluB was more common in young/middle-aged patients(both P＜0.001).The positivity rates of the six common respiratory pathogens significantly declined during the SARS-CoV-2 epidemic period,exhibiting an asynchronous seasonal pattern.Conclusions The prevalence of respiratory pathogens in Beijing is associated with age and season.Tar-geted preventive measures should be implemented in different seasons and for key populations.

Objective:To analyze the clinical application of protocol biopsy (PB) during postoperative follow-up in recipients of allogeneic kidney transplantation.Methods:A prospective observational cohort study was conducted. Recipients who underwent allogeneic kidney transplantation at the Second Affiliated Hospital of Nanjing Medical University between January 2022 and September 2024 and received PB at 3 months (±1 week) and/or 12 months (±4 weeks) post-transplantation in the Department of Nephrology were enrolled. The implementation, complications, and pathological results of PB were summarized. The safety and diagnostic efficacy of PB were analyzed.Results:A total of 143 allogeneic kidney transplant recipients were included, and 200 PB procedures were performed. The overall implementation rate of protocol biopsy (PB) was 84.1% (143/170). Among them, 170 recipients completed 3-month follow-up, and 136 PBs were performed at 3 months (±1 week) post-transplantation, with an implementation rate of 80.0%. Seventy-nine recipients completed 12-month follow-up, and 64 PBs were performed at 12 months (±4 weeks), with an implementation rate of 81.0%. One major PB-related complication occurred (0.5%), presenting as gross hematuria and diagnosed as a transplant renal arteriovenous fistula. At 3 months post-transplantation, 58 biopsies (42.6%) showed pathological abnormalities, including rejection in 12 cases (8.8%), borderline changes in 18 cases (13.2%), BK virus nephropathy (BKVN) in 10 cases (7.4%), calcineurin inhibitor (CNI) nephrotoxicity in 13 cases (9.6%), and recurrent kidney disease in 5 cases (3.7%). At 12 months post-transplantation, 22 biopsies (34.4%) revealed pathological abnormalities, including rejection in 13 cases (20.3%), borderline changes in 4 cases (6.3%), BKVN in 3 cases (4.7%), CNI nephrotoxicity in 1 case (1.6%), and recurrent disease in 1 case (1.6%).Conclusions:Protocol kidney allograft biopsy after allogeneic kidney transplantation is highly safe and feasible in clinical practice. PB provides significant diagnostic value for the early detection of subclinical rejection and BKVN, thereby supporting its clinical utility in postoperative monitoring and management.

OBJECTIVE To understand the current management status of the special campaign for enhancing the pathogen detection rate before antimicrobial therapy in hospitalized patients in China,analyze identified issues dur-ing implementation,and propose improvement suggestions.METHOD A questionnaire survey was conducted to collect data from medical institutions participating in the special campaign within the region from May to Jul.2024,covering aspects such as quality control management,coordination mechanisms,data sources,indicator connotations and existing issues.RESULTS Variations were observed among medical institutions in the manage-ment of pathogen detection rates,primarily reflected in inconsistent usage of detection rate indicators,varying im-plementation levels of quality control measures and differences in multi-departmental participation.Additionally,discrepancies in data sources,statistical methods and interpretations of indicator connotations limited the compara-bility of data.CONCLUSIONS To address these issues,improvement measures such as strengthening informatiza-tion construction,standardizing indicator statistical methods and enhancing multi-departmental coordination mech-anisms should be implemented.These efforts will provide a scientific basis for the implementation of special cam-paign and robust support for the rational use of antimicrobial agents.

Objective:To explore the effects of the 4C nursing model on pregnant women at advanced maternal age.Methods:A convenience sampling method was used to select 180 pregnant women at advanced maternal age who were receiving regular antenatal care and delivery at the Second Affiliated Hospital of Wenzhou Medical University from July 2022 to January 2024. The participants were randomly divided into the control group ( n=90) and the observation group ( n=90) using a random number table. The control group received routine care, while the observation group received the 4C nursing model in addition to routine care. Compare the scores of the Pregnancy Pressure Scale (PPS) and the Maternal Self-Management Scale between two groups of pregnant women at advanced maternal age before and after intervention.. Results:After the intervention, the scores for each dimension of the PPS in the observation group were lower than those in the control group. The scores for each dimension of the Maternal Self-Management Scale in the observation group were higher than those in the control group, with statistically significant differences ( P<0.05) . Conclusions:The 4C nursing model can reduce pregnancy-related stress and improve self-management ability in pregnant women at advanced maternal age.

Objective:To review the clinical status based on the best evidence of drug administration in patients with dysphagia, systematically analyze the obstacle factors and promoting factors in the process of evidence transformation, and formulate reform strategies.Methods:Based on the evidence-based nursing research method and the guidance of the Ottawa Model of Research Use (OMRU), the review indicators were developed based on the best evidence. The current status of clinical practice behaviors of 223 patients and 75 nurses in the Neurology, Neurosurgery and Geriatric departments of the Affiliated Hospital of Jiangsu University were reviewed from July to December 2021.Based on the results of the review, qualitative interviews were conducted with 32 potential adopters, and content analysis was used to assess the barriers and contributing factors to the clinical translation of evidence in three aspects: evidence-based change, potential adopters and practice environment, so as to develop effective strategies.Results:Based on the 22 best evidence selected, the evidence-based team developed 25 review indicators to carry out clinical review, showing that the compliance rate of 16 indicators were less than 60%. By analyzing and summarizing the interview results of potential adopters, the main obstacles leading to the low compliance rate of nurses were analyzed as follows: evidence-based reform changed the traditional work mode, and the application of evidence was not convenient; at the level of potential adopters, nurses had poor knowledge and practice, heavy work burden, and low awareness of patients and caregivers; at the level of practice environment, there was lack of nursing norms and procedures for clinical transformation of evidence, and the channels of multi-disciplinary collaboration and communication were not smooth. The main promoting factors were the perfect supervision mechanism of evidence-based nursing projects, the evidence-based group had rich experience in evidence transformation, the management was willing to change, and the practitioners were good at innovation.Conclusions:There is still a large gap between the clinical practice and the best evidence of drug administration in patients with dysphagia. The promoting factors should be fully utilized to overcome the obstacles and implement improvements to promote the effective transformation of evidence into clinical practice.
