RESUMEN
Glycolytic enzyme enolase 2 (ENO2) is dysregulated in various cancer types. Nevertheless, the role and underlying mechanism of ENO2 in clear cell renal cell carcinoma (ccRCC) remain unclear. Therefore, the current study investigated the effect and mechanism of ENO2 in ccRCC. ENO2 expression in a ccRCC cell line was assessed using reverse transcription-quantitative PCR and western blotting. Analysis of glycolysis was performed by estimating the extracellular acidification rate, lactic acid concentration, glucose uptake and the expression of glucose transporter 1, pyruvate kinase muscle isozyme M2 and hexokinase 2. Moreover, ferroptosis was assessed by detecting the level of total iron, lipid peroxide, reactive oxygen species and the expression of ferroptosis-related protein. In addition, mitochondrial function was assessed using JC-1 staining and detection kits. The results indicated that ENO2 is expressed at high levels in ccRCC cell lines, and interference with ENO2 expression inhibits glycolysis, promotes ferroptosis and affects mitochondrial function in ccRCC cells. Further investigation demonstrated that interference with ENO2 expression affected ferroptosis levels in ccRCC cells by inhibiting the glycolysis process. Mechanistically, the present results indicated that ENO2 may affect ferroptosis, glycolysis and mitochondrial functions by regulating Hippo-yes-associated protein 1 (YAP1) signaling in ccRCC cells. In conclusion, the present study showed that ENO2 affects ferroptosis, glycolysis and mitochondrial functions in ccRCC cells by regulating Hippo-YAP1 signaling, hence demonstrating its potential as a therapeutic target in ccRCC.
RESUMEN
MicroRNAs (miRNAs) are a class of small RNA genes with important roles in cancer biology regulation. There are considerable studies regarding the roles of microRNA-505-3p (miR-505-3p) in cancer development and progression, but the function of miR-505-3p in epithelial ovarian cancer (EOC) has not been fully clarified. Comparative analysis of miRNA expression data set was used to select differentially expressed miRNAs. Quantitative real-time polymerase chain reaction was applied to detect expression levels of RNAs, while western blot and immunofluorescence staining were performed to detect expression levels of proteins of interest. The motility of EOC cells was assessed by wound healing and transwell assays. The binding and regulating relationship between miRNA and its direct target gene was investigated by dual-luciferase assay. Our results show that miR-505-3p was upregulated in recurrent EOC, which significantly inhibits EOC cell motility via modulating cell epithelial-mesenchymal transition. Furthermore, our results indicated that PEAK1 expression was inhibited by direct binding of miR-505-3p into its 3'-URT in EOC cells. Importantly, knockdown of PEAK1 attenuated the effect of mi-505-3p inhibitor on EOC cell migration and invasion. In conclusion, our findings indicate that miRNA-505-3p inhibits EOC cell motility by targeting PEAK1.

The nutritional value of goat milk is determined by the composition of its fatty acids, with particular importance placed on the role of unsaturated fatty acids in promoting human health. CircRNAs have been known to affect fatty acid metabolism through different pathways. In this study, high-throughput sequencing was employed to construct expression profiles of mammary tissue harvested during the dry period and peak lactation stages of dairy goats. Differentially expressed circRNAs and mRNAs were screened, revealing significantly higher expression levels of circRNA-08436 and ELOVL6 during the peak lactation period compared with the dry period. Thus, circRNA-08436 and ELOVL6 were chosen for subsequent studies. The findings demonstrated that circRNA-08436 not only promotes the synthesis of triglyceride (TAG) and cholesterol in goat mammary epithelial cells (GMECs), but also increases the concentrations of saturated fatty acids in the cells. Through the utilization of software prediction, the dual luciferase reporter system, and qRT-PCR, it was observed that circRNA-08436 binds to miR-195, with its overexpression reducing the expression levels of miR-195 and inhibiting TAG synthesis. In addition, circRNA-08436 upregulated the expression levels of the miR-195 target gene ELOVL6. The data also revealed that YTHDC1 facilitated the transport of circRNA-08436 from the nucleus to the cytoplasm, while YTHDC2 in the cytoplasm functioned as a "reader" to identify and degrade circRNA-08436. Taken together, these findings contribute to a better understanding of the molecular regulation of fatty acid metabolism in the mammary glands of dairy goats, thus offering a sound theoretical basis for the production of high-quality goat milk.
RESUMEN
BACKGROUND: Chemotherapy, whilst treating tumours, can also lead to numerous adverse reactions such as nausea and vomiting, fatigue and kidney toxicity, threatening the physical and mental health of patients. Simultaneously, misuse of chemotherapeutic drugs can seriously endanger patients' lives. Therefore, to maintain the safety of chemotherapy for cancer patients and to reduce the incidence of adverse reactions to chemotherapy, many guidelines state that a comprehensive assessment of the cancer patient should be conducted and documented before chemotherapy. This recommended procedure, however, has yet to be extensively embraced in Chinese hospitals. As such, this study aimed to standardise the content of pre-chemotherapy assessment for cancer patients in hospitals and to improve nurses' adherence to pre-chemotherapy assessment of cancer patients by conducting a national multi-site evidence implementation in China, hence protecting the safety of cancer patients undergoing chemotherapy and reducing the incidence of adverse reactions to chemotherapy in patients. METHODS: The national multi-site evidence implementation project was launched by a JBI Centre of Excellence in China and conducted using the JBI approach to evidence implementation. A pre- and post-audit approach was used to evaluate the effectiveness of the project. This project had seven phases: training, planning, baseline audit, evidence implementation, two rounds of follow-up audits (3 and 9 months after evidence implementation, respectively) and sustainability assessment. A live online broadcast allowed all participating hospitals to come together to provide a summary and feedback on the implementation of the project. RESULTS: Seventy-four hospitals from 32 cities in China participated in the project, four withdrew during the project's implementation, and 70 hospitals completed the project. The pre-and post-audit showed a significant improvement in the compliance rate of nurses performing pre-chemotherapy assessments for cancer patients. Patient satisfaction and chemotherapy safety were also improved through the project's implementation, and the participating nurses' enthusiasm and belief in implementing evidence into practice was increased. CONCLUSION: The study demonstrated the feasibility of academic centres working with hospitals to promote the dissemination of evidence in clinical practice to accelerate knowledge translation. Further research is needed on the effectiveness of cross-regional and cross-organisational collaborations to facilitate evidence dissemination.

BACKGROUND: The internet community has become a significant source for researchers to conduct qualitative studies analyzing users' views, attitudes, and experiences about public health. However, few studies have assessed the ethical issues in qualitative research using social media data. OBJECTIVE: This study aims to review the reportage of ethical considerations in qualitative research utilizing social media data on public health care. METHODS: We performed a scoping review of studies mining text from internet communities and published in peer-reviewed journals from 2010 to May 31, 2023. These studies, limited to the English language, were retrieved to evaluate the rates of reporting ethical approval, informed consent, and privacy issues. We searched 5 databases, that is, PubMed, Web of Science, CINAHL, Cochrane, and Embase. Gray literature was supplemented from Google Scholar and OpenGrey websites. Studies using qualitative methods mining text from the internet community focusing on health care topics were deemed eligible. Data extraction was performed using a standardized data extraction spreadsheet. Findings were reported using PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) guidelines. RESULTS: After 4674 titles, abstracts, and full texts were screened, 108 studies on mining text from the internet community were included. Nearly half of the studies were published in the United States, with more studies from 2019 to 2022. Only 59.3% (64/108) of the studies sought ethical approval, 45.3% (49/108) mentioned informed consent, and only 12.9% (14/108) of the studies explicitly obtained informed consent. Approximately 86% (12/14) of the studies that reported informed consent obtained digital informed consent from participants/administrators, while 14% (2/14) did not describe the method used to obtain informed consent. Notably, 70.3% (76/108) of the studies contained users' written content or posts: 68% (52/76) contained verbatim quotes, while 32% (24/76) paraphrased the quotes to prevent traceability. However, 16% (4/24) of the studies that paraphrased the quotes did not report the paraphrasing methods. Moreover, 18.5% (20/108) of the studies used aggregated data analysis to protect users' privacy. Furthermore, the rates of reporting ethical approval were different between different countries (P=.02) and between papers that contained users' written content (both direct and paraphrased quotes) and papers that did not contain users' written content (P<.001). CONCLUSIONS: Our scoping review demonstrates that the reporting of ethical considerations is widely neglected in qualitative research studies using social media data; such studies should be more cautious in citing user quotes to maintain user privacy. Further, our review reveals the need for detailed information on the precautions of obtaining informed consent and paraphrasing to reduce the potential bias. A national consensus of ethical considerations such as ethical approval, informed consent, and privacy issues is needed for qualitative research of health care using social media data of internet communities.

OBJECTIVE: There is a strong relationship between the content of beneficial fatty acids in milk and milk fat metabolic activity in the mammary gland. To improve milk quality, it is therefore necessary to study fatty acid metabolism in bovine mammary gland tissue. In adipose tissue, peroxisome proliferator-activated receptor gamma (PPARG), the core transcription factor, regulates the fatty acid metabolism gene network and determines fatty acid deposition. However, its regulatory effects on mammary gland fatty acid metabolism during lactation have rarely been reported. METHODS: Transcriptome sequencing was performed during the prelactation period and the peak lactation period to examine mRNA expression. The significant upregulation of PPARG drew our attention and led us to conduct further research. RESULTS: According to bioinformatics prediction, dual-luciferase reporter system detection, real-time quantitative reverse transcription polymerase chain reaction and Western blotting, miR-130a and miR-130b could directly target PPARG and inhibit its expression. Furthermore, triglyceride and oil red O staining proved that miR-130a and miR-130b inhibited milk fat metabolism in bovine mammary epithelial cells (BMECs), while PPARG promoted this metabolism. In addition, we also found that the coexpression of miR-130a and miR-130b significantly enhanced their ability to regulate milk fat metabolism. CONCLUSION: In conclusion, our findings indicated that miR-130a and miR-130b could target and repress PPARG and that they also have a functional superposition effect. miR-130a and miR-130b seem to synergistically regulate lipid catabolism via the control of PPARG in BMECs. In the long-term, these findings might be helpful in developing practical means to improve high-quality milk.
RESUMEN
OBJECTIVE: This study aimed to investigate the role of FOXA1 in acute kidney injury (AKI) induced by radiotherapy in colorectal cancer. Although FOXA1 is known to be aberrantly expressed in malignant tumors, its contribution to AKI remains unclear. This study aimed to explore the involvement of FOXA1 in AKI induced by radiotherapy in colorectal cancer and its influence on the regulation of downstream target genes. METHODS: Firstly, a transcriptome analysis was performed on mice to establish a radiation-induced AKI model, and qPCR was used to determine the expression of FOXA1 in renal cell injury models induced by X-ray irradiation. Additionally, FOXA1 was silenced using lentiviral vectors to investigate its effects on the apoptosis of mice with radiation-induced AKI and HK-2 cells. Next, bioinformatics analysis and various experimental validation methods such as ChIP assays, co-immunoprecipitation, and dual-luciferase reporter assays were employed to explore the relationship between FOXA1 and the downstream regulatory factors ITCH promoter and the ubiquitin ligase-degradable TXNIP. Finally, lentiviral overexpression or knockout techniques were used to investigate the impact of the FOXA1/ITCH/TXNIP axis on oxidative stress and the activation of inflammatory body NLRP3. RESULTS: This study revealed that FOXA1 was significantly upregulated in the renal tissues of mice with radiation-induced AKI and in the injured HK-2 cells. Furthermore, in vitro cell experiments and animal experiments demonstrated that FOXA1 suppressed the transcription of the E3 ubiquitin ligase ITCH, thereby promoting apoptosis of renal tubular cells and causing renal tissue damage. Further in vivo animal experiments confirmed that TXNIP, a protein degraded by ITCH ubiquitination, could inhibit oxidative stress and the activation of NLRP3 inflammasome in the AKI mouse model. CONCLUSION: FOXA1 enhances oxidative stress, cell apoptosis, and NLRP3 inflammasome activation by regulating the ITCH/TXNIP axis, thereby exacerbating radiotherapy-induced AKI.

BACKGROUND: The substantial rise in the population of older adults living with disabilities is a prominent concern, presenting a profound challenge for healthcare and social welfare systems. Community-based home care is seen as an effective approach to meet the care needs of older adults living with disabilities. OBJECTIVE: To construct a coping target checklist for home-based older adults living with disabilities and their spousal caregivers. METHODS: The initial draft was developed based on a comprehensive literature review, followed by two rounds of Delphi correspondence final version. RESULTS: A comprehensive literature review resulted in the development of 7 modules, 20 topics. After round 1, 3 items were removed, 3 sections, 1 topic and 1 objective were new additions, 16 items were modified, split or combined. Four sections, 3 sections (Individual coping target for spousal caregivers, Individual coping target for older adults living with disabilities, and Shared coping target), 7 modules, 18 topics and 49 objectives were finally identified in round 2. The content of the list tool is derived from three perspectives: self-management strategies for older adults living with disabilities, caregiving strategies for spousal caregivers, and combined. CONCLUSIONS: The coping target checklist was intended to be evidence-based and reflective of a practical direction for home-based older adults living with disabilities and their spousal caregivers living at home.

AIM: The aim of this study was to synthesize the self-management theory, model and frameworks of patients with chronic heart failure, focusing on construction process, methods and existing problems. BACKGROUND: Although the self-management theories have been created and verified for those patients with chronic heart failure, no reviews have been performed to integrate these theories. DESIGN: A scoping review of recent literature (without a date limit) was conducted. METHODS: A comprehensive literature search was performed. If the study reported the construction of a self-management theory, model or framework about chronic heart failure cases, it would be included in the review. RESULTS: Fourteen studies were included, which could be categorized into situation-specific theory, middle-range theory and other theory models (including conceptual model, hypothetic regression model and identity description model). It also includes the update and validation of theories, the situation-specific theoretical of caregiver contributions extended from situation-specific theories and the nurse-led situation-specific theory in different contexts. CONCLUSION: Self-management might contribute to start an education programme before patients with chronic heart failure (CHF) begin their chronic disease live as an individual. Our scoping review indicates that a series of self-management theories, models and frameworks for CHF patients have been developed, but more studies are still needed to validate and support these theories according to their cultural contexts.

BACKGROUND: Tracheostomy tube changes are a considerable part of the management of patients with tracheostomy and are necessary for preventing aspiration pneumonia, especially in patients with long-term tracheostomy. The process of tracheostomy tube changes in many patients may not be timely, safe or efficient. OBJECTIVE: The objectives were to implement a quality improvement intervention that reduces the incidence of aspiration pneumonia in patients with tracheostomy, improve staff knowledge about tracheostomy tube changes and improve staff adherence to documentation. METHODS: A pre-post intervention design was used in this quality improvement project. We created a change strategy bundle that included identification of the need for and observation determination of the timing of tube changes timing, change assessments, identification of the person and location, preparation, co-operation and maintenance. A tracheostomy tube change workflow was also created. Then, the intervention was implemented in the clinic after staff training. The incidence of aspiration pneumonia, staff knowledge and staff adherence were compared before and after the intervention. RESULTS: Two hundred and 20 patients were enrolled (105 in the preintervention group; 115 in the postintervention group) with 88 tracheostomy tube change episodes (23 in the preintervention group; 65 in the postintervention group). Thirty-five staff members completed the training and surveys. The incidence of pneumonia decreased from 43.8% to 27.8% after the intervention (p = .013). The knowledge score of staff increased from 46.57 ± 11.10 to 88.14 ± 6.76, and the implementation rate of the audit increased to 67.32%-100%. CONCLUSIONS: This quality improvement project regarding tracheostomy changes reduced the incidence of pneumonia, increased staff knowledge about tracheostomy tube changes and improved staff adherence. RELEVANCE TO CLINICAL PRACTICE: A standardized tracheostomy tube change bundle, education, interprofessional collaboration and culture changes were important to ensure the best outcomes in this quality improvement project. These factors improved the timeliness, efficiency and safety of tracheostomy tube changes.
RESUMEN
Biotransformation of ursonic acid (1) by two fungal strains Aspergillus ochraceus CGMCC 3.5324 and Aspergillus oryzae CGMCC 3.407 yielded thirteen new compounds (4, 5, 7-10, and 13-19), along with five recognized ones. The structural details of new compounds were determined through spectroscopic examination (NMR, IR, and HR-MS) and X-ray crystallography. Various modifications, including hydroxylation, epoxidation, lactonization, oxygen introduction, and transmethylation, were identified on the ursane core. Additionally, the anti-neuroinflammatory efficacy of these derivatives was assessed on BV-2 cells affected by lipopolysaccharides. It was observed that certain methoxylated and epoxylated derivatives (10, 16, and 19) showcased enhanced suppressive capabilities, boasting IC50 values of 8.2, 6.9, and 5.3 µM. Such ursonic acid derivatives might emerge as potential primary molecules in addressing neurodegenerative diseases.

The stress of disability significantly impacts an individual's quality of life and that of a spouse. Health empowerment, based on the idea that individuals may be successful despite disability, may be meaningful to disabled persons and their spouse carers. This cross-sectional survey study aimed to explore the effect of health empowerment on the health-related quality of life (HRQOL) of older individuals with disabilities and their spouse carers on both a personal (actor effect) and interpersonal level (partner effect). A total of 1092 dyads of older individuals with disabilities and their spouse carers residing in communities were recruited from seven provinces in China. Two separate Actor-Partner Interdependence Model analyses were conducted to examine the impact of health empowerment on the two domains of HRQOL: the Physical Component Score (PCS) and the Mental Component Score (MCS). The results revealed that health empowerment had actor effects on the PCS and MCS of older individuals with disabilities, as well as on the PCS and MCS of their spouse carers. However, no significant partner effects of health empowerment on the PCS and MCS of either the individuals with disabilities or their spouse caregivers were observed. Empowering individuals with disabilities and their spouse carers may help them enhance their own HRQOL, both physically and mentally. However, more research is required to determine the interpersonal effect of health empowerment on the HRQOL.

OBJECTIVES: To conduct psychometric testing of the Chinese version of the National Health Service Sustainability Model as an instrument to assess the sustainability of innovation in the Chinese nursing setting. BACKGROUND: Evidence-based practice is recognized worldwide as a way to improve the quality of healthcare; however, many evidence-based practice programmes decline over time and do not sustain the benefits of their improvements. A sustainability assessment tool is used internationally but its use has not been validated in China. DESIGN: A methodological study to test instrument validity and reliability. METHODS: The data collection was conducted from 15 June 2022 to 31 August 2022. The internal consistency of the Chinese version of the sustainability model was measured with Cronbach's alpha. Confirmatory factor analysis was used to test the model's structural validity. RESULTS: Four hundred eighty-three questionnaires were returned, of which 478 were valid. The short time taken to evaluate the Chinese version of the sustainability model demonstrated its efficiency and ability to adapt to a busy clinical environment. The confirmatory factor analysis showed a good fit model and supported the convergence validity of the sustainability model. The Cronbach's alpha coefficient was 0.905 for the total scale, which indicated good internal consistency. CONCLUSIONS: The results of this study suggest that the Chinese version of the sustainability model is a valid, reliable and efficient tool for measuring the sustainability of evidence-based practices in Chinese nursing settings.
RESUMEN
BACKGROUND: The innovative method of sentiment analysis based on an emotional lexicon shows prominent advantages in capturing emotional information, such as individual attitudes, experiences, and needs, which provides a new perspective and method for emotion recognition and management for patients with breast cancer (BC). However, at present, sentiment analysis in the field of BC is limited, and there is no emotional lexicon for this field. Therefore, it is necessary to construct an emotional lexicon that conforms to the characteristics of patients with BC so as to provide a new tool for accurate identification and analysis of the patients' emotions and a new method for their personalized emotion management. OBJECTIVE: This study aimed to construct an emotional lexicon of patients with BC. METHODS: Emotional words were obtained by merging the words in 2 general sentiment lexicons, the Chinese Linguistic Inquiry and Word Count (C-LIWC) and HowNet, and the words in text corpora acquired from patients with BC via Weibo, semistructured interviews, and expressive writing. The lexicon was constructed using manual annotation and classification under the guidance of Russell's valence-arousal space. Ekman's basic emotional categories, Lazarus' cognitive appraisal theory of emotion, and a qualitative text analysis based on the text corpora of patients with BC were combined to determine the fine-grained emotional categories of the lexicon we constructed. Precision, recall, and the F1-score were used to evaluate the lexicon's performance. RESULTS: The text corpora collected from patients in different stages of BC included 150 written materials, 17 interviews, and 6689 original posts and comments from Weibo, with a total of 1,923,593 Chinese characters. The emotional lexicon of patients with BC contained 9357 words and covered 8 fine-grained emotional categories: joy, anger, sadness, fear, disgust, surprise, somatic symptoms, and BC terminology. Experimental results showed that precision, recall, and the F1-score of positive emotional words were 98.42%, 99.73%, and 99.07%, respectively, and those of negative emotional words were 99.73%, 98.38%, and 99.05%, respectively, which all significantly outperformed the C-LIWC and HowNet. CONCLUSIONS: The emotional lexicon with fine-grained emotional categories conforms to the characteristics of patients with BC. Its performance related to identifying and classifying domain-specific emotional words in BC is better compared to the C-LIWC and HowNet. This lexicon not only provides a new tool for sentiment analysis in the field of BC but also provides a new perspective for recognizing the specific emotional state and needs of patients with BC and formulating tailored emotional management plans.

BACKGROUND: Given the rapid development of social media, effective extraction and analysis of the contents of social media for health care have attracted widespread attention from health care providers. As far as we know, most of the reviews focus on the application of social media, and there is a lack of reviews that integrate the methods for analyzing social media information for health care. OBJECTIVE: This scoping review aims to answer the following 4 questions: (1) What types of research have been used to investigate social media for health care, (2) what methods have been used to analyze the existing health information on social media, (3) what indicators should be applied to collect and evaluate the characteristics of methods for analyzing the contents of social media for health care, and (4) what are the current problems and development directions of methods used to analyze the contents of social media for health care? METHODS: A scoping review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was conducted. We searched PubMed, the Web of Science, EMBASE, the Cumulative Index to Nursing and Allied Health Literature, and the Cochrane Library for the period from 2010 to May 2023 for primary studies focusing on social media and health care. Two independent reviewers screened eligible studies against inclusion criteria. A narrative synthesis of the included studies was conducted. RESULTS: Of 16,161 identified citations, 134 (0.8%) studies were included in this review. These included 67 (50.0%) qualitative designs, 43 (32.1%) quantitative designs, and 24 (17.9%) mixed methods designs. The applied research methods were classified based on the following aspects: (1) manual analysis methods (content analysis methodology, grounded theory, ethnography, classification analysis, thematic analysis, and scoring tables) and computer-aided analysis methods (latent Dirichlet allocation, support vector machine, probabilistic clustering, image analysis, topic modeling, sentiment analysis, and other natural language processing technologies), (2) categories of research contents, and (3) health care areas (health practice, health services, and health education). CONCLUSIONS: Based on an extensive literature review, we investigated the methods for analyzing the contents of social media for health care to determine the main applications, differences, trends, and existing problems. We also discussed the implications for the future. Traditional content analysis is still the mainstream method for analyzing social media content, and future research may be combined with big data research. With the progress of computers, mobile phones, smartwatches, and other smart devices, social media information sources will become more diversified. Future research can combine new sources, such as pictures, videos, and physiological signals, with online social networking to adapt to the development trend of the internet. More medical information talents need to be trained in the future to better solve the problem of network information analysis. Overall, this scoping review can be useful for a large audience that includes researchers entering the field.

INTRODUCTION: Poststroke depression (PSD) is common but insufficiently addressed by health professionals, and management is not always evidence-based. OBJECTIVES: This evidence implementation project aimed to improve adherence to evidence-based practice for screening, prevention, and management of patients with PSD in the neurology ward of the Fifth Affiliated Hospital of Zunyi Medical University, China. METHODS: This project was based on the JBI methodological approach and was conducted in three phases, from January to June 2021: a baseline audit, implementation of strategies, and a follow-up audit. We utilized the JBI Practical Application of Clinical Evidence System software and the Getting Research into Practice tools. Fourteen nurses, 162 stroke patients, and their caregivers participated in this study. RESULTS: The results of the baseline audit showed that compliance with evidence-based practice was poor, with 3/6 criteria showing 0% adherence and the other three audit criteria showing 5.7, 10.3, and 49.4% adherence, respectively. Through feedback to nurses regarding the baseline audit results, the project team identified five barriers and adopted a battery of strategies to overcome these barriers. The follow-up audit revealed significantly enhanced outcomes across all the best practice criteria, and the compliance of each criterion reached at least 80%. CONCLUSION: The implementation program designed to screen, prevent, and manage PSD in a tertiary hospital in China improved nurses' knowledge and compliance with evidence-based management of PSD. Further testing of this program in more hospitals is needed.

Background: There is no consensus on whether intravenous rehydration must be added after preoperative phenoxybenzamine (PXB) administration for pheochromocytoma. The aim of this study is to investigate whether abandonment of intravenous volume expansion after PXB administration is associated with intraoperative hemodynamic instability. Methods: 83 Patients with pheochromocytoma received surgical treatment in the Department of Urology, Handan First Hospital, between October 2014 and July 2022. All patients were subclassified into either the hemodynamic stability group (HS group) or the hemodynamic instability group (HU group) according to whether intraoperative hemodynamic instability occurred, with 51 cases in HS group and 32 cases in HU group. Differences in data between the two groups were examined, and the risk factors for intraoperative hemodynamic instability were analyzed using logistic regression. Results: The results of the analysis showed no statistically significant differences in age, sex, location of the tumor, surgical method, body mass index (BMI) ≥ 24 kg/m2, blood and urine catecholamine test results, preoperative oral PXB followed by combined intravenous volume expansion, proportion of patients with hypertension or diabetes mellitus or coronary heart disease between the two groups (P>0.05). The size of the tumor in the HS group was smaller than that in the HU group (5.3 ± 1.9 cm vs 6.2 ± 2.4 cm P=0.010). Multivariate analyses demonstrated that abandonment of intravenous volume expansion after preoperative receipt of α-blockers in patients with adrenal pheochromocytoma was not an independent risk factor for intraoperative hemodynamic instability. Only the tumor size (P=0.025) was an independent risk factor for intraoperative hemodynamic instability. Conclusion: The purpose of general preoperative intravenous fluid expansion is to prevent hypotension after the tumor has been resected. In the current study, we indicated that preoperative management of pheochromocytomas using the α-blocker PXB in combination with intravenous volume expansion does not further reduce the risk of intraoperative hemodynamic instability or postoperative complications compared with oral PXB alone. Therefore, our study supports preoperative management of pheochromocytoma with a single α-blocker, PXB, as sufficient.

BACKGROUND: International attention is being paid to the issue of making evidence sustainable after implementation. Developing an identification model is essential to promote and monitor the sustainability of evidence implementation. However, this model is not available in Chinese. This study aims to translate the National Health Service Sustainability Model into Chinese and to verify whether the model is adapted to the Chinese healthcare environment. METHODS: This study follows the translation and validation guidelines developed by Sousa and Rojjanasrirat. The translations include forward and backward translations and their comparison. Expert reviews were used to validate the content validity of the Chinese version of the National Health Service sustainability model. Cognitive interviews were used to assess the validity of the language in the Chinese setting. RESULTS: The translation was conducted by a bilingual research team and took 12 months. Expert reviews were undertaken with eight experts, and cognitive interviews with six participants. The content validity of the model is excellent, but at least 20% of the experts still felt that items one, three, five and nine needed refinements. In the cognitive interviews, most items, instructions and response options were well understood by the participants responsible for the evidence-based practice project. However, some language issues were still identified in items one, three, four, five, seven, nine, and ten. Participants reported that the sustainability results of the model assessment were consistent with their previous judgments of the items. Based on the expert review and interview results, items one, three, four, five, seven, nine and ten require further refinement. In summary, seven of the ten items have been amended. CONCLUSIONS: This study provides insight into how the National Health Service sustainability model can be used in the Chinese healthcare setting and paves the way for future large-scale psychometric testing.
