Objective To explore the potential contributors and obstacles of evidence translation for airway hu-midification management in hospitalized patients with laryngectomy tracheostomy and non-mechanical ventilation,so as to provide references for clinical evidence-based practice.Methods An interview outline and questionnaire were developed according to the consolidated framework for implementation research(CFIR).Using purposive sampling,12 healthcare professionals from Department of Otorhinolaryngology,Head and Neck Surgery of a tertiary hospital in Shanxi Province were recruited for semi-structured interviews,and thematic analysis was applied to extract main themes.The interview themes were transformed into survey items,and a survey was conducted among 42 healthcare professionals in the same department.Results Totally 16 contributors and 20 obstacles were identified across 4 domains:the credibility of the evidence and research team,the external support environment for evidence-based practice,the internal conditions for evidence-based practice,and the role recognition of implementers.Contributors include efficient internal collaboration and communication,and rigorous processes for evidence acquisition.Obstacles include insufficient educational resources,low patient knowledge acceptance capacity,lack of professional value a-mong healthcare staff.Conclusion Evidence translation of the humidification management for patients with non-mechanical ventilation after laryngectomy and tracheostomy was influenced by various factors.Future efforts should focus on constructing targeted airway humidification education content and an evaluation index system,and enhanc-ing the professional value and practical leadership of nursing staff.

Objective To compare the effects of quadratus lumborum block at the lateral supra-arcuate ligament(QLB-LSAL)versus subcostal transversus abdominis plane block(STAPB)on perioperative analgesia and postoperative inflammation in patients undergoing laparoscopic radical resection of colorectal cancer.Methods In this prospective randomized study,we recruited 102 patients undergoing laparoscopic colorectal cancer surgery between October 2022 and October 2024 under general anesthesia and randomly assigned them to two groups:QLB-LSAL(Group Q,n=51)and STAPB(Group S,n=51).Mean arterial pressure(MAP)and heart rate(HR)were recorded before anesthesia induction(T0),before surgical incision(T1),start of surgery(T2),during pneumoperitoneum establishment(T3),during peritoneal lavage(T4),at the end of surgery(T5),and upon leaving the operating room(T6).Intraoperative remifentanil consumption,time to first patient-controlled analgesia demand,and frequency of effective compression and rescue analgesia were recorded.Visual Analog Scale(VAS)scores at rest and during coughing were assessed at 24,48,and 72 hours postoperatively.Interleukin-6(IL-6)and systemic immune-inflammatory index(SII)at 1 day preoperatively,1,and 3 days postoperatively were recorded.Postoperative recovery indicators and adverse events were also recorded.Results Group Q demonstrated significantly lower MAP and HR compared with Group S from T3 to T6(P<0.05).Group Q had significantly lower intraoperative remifentanil consumption,significantly longer time to first analgesic pump demand,fewer effective pump compres-sion,and lower frequency for rescue analgesia requests(all P<0.05).VAS scores at rest and during coughing in Group Q were significantly lower at 24 h and 48 h postoperatively(P<0.05).As compared with preoperative levels,both IL-6 and SII increased at 1 and 3 days postoperatively,but magnitude of increase in Group Q was smaller than in Group S(P<0.05).In comparison to Group S,Group Q demonstrated significantly earlier ambulation,shorter hospital stay,and fewer adverse events(P<0.05).Conclusion QLB-LSAL is superior to STAPB in enhancing perioperative analgesia,attenuating inflammatory response,and accelerating postoperative rehabilitation in patients undergoing laparoscopic colorectal cancer resection.

Objective Under the guidance of the Social Ecosystems Theory(SET)framework,this study explores the experience of social isolation among patients with chronic obstructive pulmonary disease(COPD),providing a basis for the development of targeted clinical interventions.Methods This study employed purposeful sampling methods.Semi-structured interviews were conducted from April to July 2024 with patients diagnosed with COPD at a tertiary hospital in Shanxi Province,China,who met the inclusion and exclusion criteria.Data were analyzed using Colaizzi's seven-step analysis method and NVivo 12.0 software.Results This study involved in-depth interviews with 15 patients suffering from COPD,totaling approximately 405 minutes of interview time and yielding over 40,000 words in transcribed text.Totally 3 main themes and 9 sub-themes were distilled,among which the microsystem level reflects the intricate interplay of individual experiences(physical functional limitations,severe negative emotions,heightened emotional imbalance,and weakened social roles);the mesosystem level pertains to the support and challenges from family and social networks(intense need for familial emotional support,widening social gaps in interactions with friends and relatives,and pronounced interpersonal communication barriers);the macrosystem level involves the integrated influence of societal and policy environments(restricted living conditions and urgent demands for policy support and service accessibility).Conclusion The social isolation experienced by patients with COPD manifests in multiple dimensions of experience.It is necessary to develop interdisciplinary and multi-level comprehensive intervention strategies for the future,to create more social opportunities and emotional connections for patients,thereby improving their quality of life.

Objective:To comprehensively identify, describe and evaluate the research evidence on the application of ERAS in perioperative head and neck cancer by using the method of evidence mapping, so as to understand the research status and provide reference for clinical practice and future research in this field.Methods:Adopting an evidence-integrated research approach, PubMed, Embase, CINAHL, Web of Science, Cochrane Library, CNKI, Wanfang, VIP and Chinese Biomedical Literature Database were searched by computer. In addition, relevant references and grey literature databases such as OpenGrey were manually searched until August 25, 2024, to screen and summarize the included literature, and different quality evaluation tools were used to evaluate the quality of the included studies. The present research situation was presented with text and graphs.Results:A total of 105 articles were included, including 101 original studies and 4 systematic reviews/Meta-analyses. The number of published literature showed an increasing trend over time, but it fluctuated in a zigzag pattern. The most published studies were in China, and the study population was mainly patients with laryngeal and oral cancer, with a sample size of 51-100 cases. The results of methodology quality evaluation showed that the quality of most studies was relatively low. The intervention measures mainly involved 9 subjects, such as pre-rehabilitation, nutritional support, prevention of nausea and vomiting, and the outcome indicators involved 2 aspects related to patients and hospital. More attention was paid to outcome indicators such as complication rate and length of stay, while less attention was paid to outcome indicators such as condition of sputum and survival time. Most outcome effects were shown to be "beneficial", but some outcome effects were still controversial.Conclusions:ERAS has generally shown positive effects in perioperative application of head and neck cancer, but the quality of most studies is low. More high-quality clinical studies are needed in the future to provide more sufficient evidence for the application of ERAS in this field.

【Objective】 To investigate the condition of confidential unit exclusion(CUE) in Guangzhou, so as to ensure blood safety. 【Methods】 The number of CUE donors, demographic characteristics of CUE donors, reasons for CUE, and response time of CUE after blood donation in Guangzhou from 2009 to 2022 were statistically analyzed. 【Results】 From 2009 to 2022, the response ratios of CUE was 0.006 2% (260/4 170 984) and the ratios had statistically significant difference between different years(P<0.05). For the response ratios of CUE, no statistically significant difference was noticed in gender and occupation (P>0.05), but statistically significant differences were found in age, number of blood donations, education background, and marital status (P<0.05). Blood donors aged 18~30 (0.007 3%, P<0.05) and first-time blood donors (0.010 8%, P<0.05) were the main groups of CUE. High risk sexual behavior (28.46%, 74/260) was the primary reason for CUE. The CUE response peak was within 72 hours after blood donation, and the response ratios within 24-72 hours after blood donation was the highest (68.46%, 178/260). 【Conclusion】 CUE is a crucial measure to ensure blood safety. Detailed pre-donation health consultations are suggested for blood donors aged 18-30 and first-time blood donors so as to better excluding high-risk blood donors. Strengthening the publicity of CUE response and process, registering and classifying the reasons for CUE are also important.

Objective To analyze the clinical outcomes of early invasive fungal disease(IFD)in patients after allogenetic hematopoietic stem cell transplantation(allo-HCST)with metagenomic next-generation sequencing(mNGS).Methods A retrospective analysis was conducted on patients undergoing allo-HCST in our Bone Marrow Transplantation Center between July 2021 and October 2022.These patients experienced one of the following conditions within 100 d after transplantation:① Patients with persistent fever and negative blood culture after empiric antimicrobial therapy for 72 h or longer;② Hyperpyrexia of unknown origin occurred again after effective anti-infection in the past;③ Symptoms in lower respiratory tract associated with lung lesions on CT scan,and empiric anti-infective therapy was ineffective.Peripheral blood or bronchoscopic alveolar lavage fluid were tested with mNGS,and overall survival(OS)and non-relapse mortality(NRM)were analyzed.Results There were 60 patients enrolled in this study.For the peripheral blood samples of 47 cases and bronchoalveolar lavage fluid samples of 13 cases,mNGS found that 19 cases were negative to pathogens,30 cases were non-fungal positive,and 11 case were fungal positive,including 3 cases of aspergillus,5 cases of mucor,2 cases of Candida tropicalis,and 1 case of Trichosporon asahii.Of the 11 patients with fungal positive,8 achieved complete remission after antifungal therapy according to the mNGS results.The 1-year OS and NRM of the 60 patients were 70.0％(95％CI:64.1％～75.9％)and 20.0％(95％CI:11.9％～32.5％),respectively,while those of the fungal infection patients were 54.5％(95％CI:49.5％～69.5％)and 36.4％(95％ CI:15.5％～70.3％),respectively.No significant differences were seen in 1-year OS(P=0.487)and 1-year NRM(P=0.358)among the negative,fungal infection and non-fungal infection patients,neither OS(P=0.238)and NRM(P=0.154)between the fungal infection and the non-fungal infection patients.Conclusion mNGS can rapidly diagnose the early IFD after allo-HSCT,which is helpful for timely and effective treatment and improves the prognosis of patients.
