Objective To investigate the relationships of serum procalcitonin(PCT),α1-acid glycoprotein(α1-AGP)and cluster of differentiation 64(CD64)index with the severity of illness and prognosis in patients with pulmonary Candida infection after lung cancer surgery.Methods A pro-spective study was conducted in 120 patients with pulmonary Candida infection after lung cancer sur-gery as infection group,and 60 patients without infection after lung cancer surgery in the same period were selected as control group.Baseline characteristics and laboratory indicators were compared be-tween the two groups.Differences in serum PCT,α1-AGP,CD64 index in peripheral blood,and plasma 1,3-β-D glucan test(BG)were compared among patients with different severities of illness and prognoses in the infection group.The relationship between serum indicators and prognosis as well as their predictive efficiencies were analyzed,and external validation was performed.Results The levels of serum PCT,α1-AGP,CD64 index in peripheral blood,and plasma BG in the infection group were significantly higher than those in the control group(P＜0.05).In the infection group,the levels of serum PCT,α1-AGP,and CD64 gradually decreased significantly in patients with severe,moderate,and mild illness,and the levels of these indicators in dead patients were significantly higher than those in surviving patients(P＜0.05).Survival curve analysis showed that patients with low levels of serum PCT,α1-AGP,and CD64 index before treatment had higher survival rates than those with high levels of these indicators.Receiver operating characteristic(ROC)curve analysis revealed that the combined prediction of PCT,α1-AGP,and CD64 index for mortality was superior to individual indicators or their pairwise combinations,and external validation confirmed the good predictive efficacy of the combined prediction.Conclusion PCT,α1-AGP,and CD64 index are closely related to pulmonary Candida infection after lung cancer surgery,and the combined detection of these indicators has certain predictive value for 28-day prognosis.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Objective To explore the work experiences and needs of nutrition specialist nurses,so as to provide a basis in career development and management practices among the nutrition specialist nurses.Methods A method of descriptive phenomenological research was adopted in this study.Purposive sampling was used to select 12 nutrition specialist nurses who came from different regions across the country with over one year of clinical working experiences as well as had completed the specialist training and been qualified by the Nutrition Committee of Guangdong Nursing Association between January and February 2024.Semi-structured on-line interviews were conducted among the participants and the data acquired from the interviews were analysed and summarised.Themes were extracted using NVivo12 and Colaizzi's seven-step analysis from the data from interview.Results Three main themes and eight sub-themes were identified regarding the work experience of nutrition specialist nurses:growth and gains(continuously learning in nutrition therapy-related knowledge to enhance professional skills;actively practice in nutrition therapy to achieve the self-worth);sense of responsibility and mission(increased awareness of responsibility and proactive services;sense of mission to cultivate talents and promotion of the development of nutrition nursing discipline);challenges(lack of an established role in nutrition nursing,conflict in responsibilities;insufficient communication in a medical team regarding nutrition therapy;limited resource to support the development of nutrition nursing;and the professional knowledge and skills unable to fully meet the job demands).Conclusion Hospitals managers should strengthen the support and training for nutrition specialist nurses,clarify their roles,leverage their professional value and promote the career development.

Objective To explore the current status of penile erection hardness and its influencing factors in patients with non-obstructive azoospermia.Methods From January to December 2024,450 patients with non-obstructive azoospermia were surveyed at the Reproductive Medicine Center of Hospital.A self-made general information questionnaire was used to collect their demographic data.The Erectile Hardness Scale(EHS)was employed to investigate the current status of their penile erection hardness,and a self-made questionnaire was utilized to explore the influencing factors.Results Among the 450 patients with non-obstructive azoospermia,during sexual intercourse,35.3%of the patients reported that their penile erection hardness could reach grade 4(normal state),54.5%reported that it only reached grade 3(sub-optimal state),9.3%reported that it only reached grade 2(slight penile erection),and 0.9%reported that it only reached grade 1(inability to achieve an erection).In the survey of satisfaction with sexual life quality,among the 450 patients,only 24.9%were very satisfied with their sexual life quality;57.3%were basically satisfied;9.6%considered it average;4.0%were dissatisfied;3.1%were very dissatisfied;and 1.1%had no sexual life.alcohol consumption(OR=2.393,95%CI:1.493～3.836),satisfaction with the quality of sexual life(OR=1.455,95%CI:1.118～1.894),educational attainment(OR=0.709,95%CI:0.549～0.917),and the sleep quality in the past month(OR=0.641,95%CI:0.452～0.907).Conclusions Clinical studies have shown that factors such as drinking habits,sexual life satisfaction,sleep quality,and educational attainment collectively influence the penile erection hardness in patients with non-obstructive azoospermia.Therefore,the medical team needs to customize personalized intervention plans and educational materials based on individual differences among patients.Through psychological counseling and lifestyle guidance,they can improve erectile function and the quality of sexual life,promote harmonious marital relationships,and enhance the overall life experience of the patients.

Objective:To establish the standard of nursing quality in bone oncology department, and provide the basis for scientific evaluation of nursing quality in bone oncology department.Methods:On the theoretical basis of Donabedian′s three-dimensional quality model of "structure-process-outcome", and through literature review and semi-structured interview method, the "evaluation index of nursing quality in bone oncology department" was preliminatively formulated from November 2022 to June 2023. The Delphi method was used to select 31 experts from 31 third-level A hospitals and nursing colleges in 27 provinces or municipalities across the country for two rounds of correspondence consultation. The criteria were screened and modified to determine the evaluation criteria of nursing quality in bone tumor specialty.Results:The questionnaire recovery rate of 2 rounds of expert consultation was 100.00%, the authority coefficient of 2 rounds of expert consultation was 0.93, and the coefficient of variation of 1, 2 and 3-grade standards were all less than or equal to 0.25. The Kendall′s coefficient of concordance of the primary standards of the two rounds of expert consultation were both 0.088, in the secondary standards were 0.103 and 0.140, in the tertiary standards were 0.119 and 0.110. Through 2 rounds of expert letter consultation, the evaluation criteria for the quality of care in bone tumor specialties were divided into three levels, including 3 primary standards (structural quality criteria, process quality criteria and outcome quality criteria), 21 secondary standards and 80 tertiary standards.Conclusions:The construction process of nursing quality standard in bone oncology department is scientific and reliable, reflecting specialty characteristics, and can provide scientific basis for the evaluation of nursing quality in bone oncology department and standardize nursing behavior.
