To synthesize available evidence about core competencies for nurses engaged in palliative care.
A scoping review conducted according to the framework from Joanna Briggs Institute.
The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist was adopted to report this scoping review. The PubMed, Web of Science, Embase, ScienceDriect, CNKI, WangFang, VIP and Sinomed databases were used to systematically search for published studies from their inception to December 2023. Two researchers independently screened and selected relevant studies and performed the data charting.
Twenty-six studies were included in this scoping review. Among these, 14 studies identified core competency assessment instruments among nurses engaged in palliative care, with the Palliative Care Core Competence Questionnaire was used most frequently; 13 studies investigated the status of core competencies of nurses engaged in palliative care, the majority of included studies indicated that nurse's core competencies were at moderate levels; 11 studies explored the factors influencing the core competencies of the nurses engaged in palliative care, which were classified as sociodemographic-related factors, palliative care education-related factors, death attitude, palliative care practice-related experience and others.
This scoping review offers a comprehensive overview of the current landscape of core competencies among nurses in palliative care. Findings suggested that the clinical nursing leaders need to develop tailored strategies and interventions to address specific factors and promote the continuous development of nurses' competencies in palliative care.
Core competency assessment instruments equip nurses and healthcare organizations with a range of validated tools for evaluating their proficiency in palliative care. Targeted core competency enhancement programmes need to be developed to foster a nursing workforce better equipped to improve the quality of life of end-of-life patients and their families.

The objective of this study was to construct and validate a structural equation model (SEM) to identify factors associated with sleep quality in awake patients in the intensive care unit (ICU) and to assist in the development of clinical intervention strategies.
In this cross-sectional study, 200 awake patients who were cared for in the ICU of a tertiary hospital in China were surveyed via several self-report questionnaires and wearable actigraphy sleep monitoring devices. Based on the collected data, structural equation modelling analysis was performed using SPSS and AMOS statistical analysis software. The study is reported using the STROBE checklist.
The fit indices of the SEM were acceptable: χ2/df = 1.676 (p < .001) and RMSEA = .058 (p < 0.080). Anxiety/depression had a direct negative effect on the sleep quality of awake patients cared for in the ICU (β = −.440, p < .001). In addition, disease-freeness progress had an indirect negative effect on the sleep quality of awake patients cared for in the ICU (β = −.142, p < .001). Analgesics had an indirect negative effect on the sleep quality of awake patients cared for in the ICU through pain and sedatives (β = −.082, p < .001). Sedation had a direct positive effect on the sleep quality of conscious patients cared for in the ICU (β = .493; p < .001).
The results of the SEM showed that the sleep quality of awake patients cared for in the ICU is mainly affected by psychological and disease-related factors, especially anxiety, depression and pain, so we can improve the sleep quality of patients through psychological intervention and drug intervention.
Establishing a nomogram to estimate the probability of oral mucosal membrane pressure injury of endotracheal tube-intubated hospitalized patients in intensive care unit.
Multicentre prospective cohort study.
Using Lasso regression and COX regression, variable selection was performed on demographic, clinical and laboratory data of 1037 ICU endotracheal tube-intubated hospitalized patients from West China Hospital, to construct a nomogram. External validation was conducted on 484 ICU endotracheal tube-intubated patients from People's Hospital of Zhongjiang County.
Among 38 potential predictors, five variables emerged as independent predictors, integrated into the nomogram: administration of antibiotics, nutritional therapy duration, agitation, hypotension and albumin levels.
We established a nomogram based on the hospital characteristics of ICU endotracheal tube-intubated patients, aiding in the prediction of the occurrence of oral mucosal membrane pressure injury.
The study followed TRIPOD guidelines.
The nomogram we developed can assist clinical worker in better identifying at-risk patients and risk factors. It enables the implementation of evidence-based nursing interventions in care to prevent the development of oral mucosal membrane pressure injury.
The study has been registered with the Chinese Clinical Trial Registry (http://www.chictr.org.cn) under registration number ChiCTR2200056615.
To identify the multiple mediating effects of resilience and depression between social support and self-care ability among patients with breast cancer during rehabilitation to provide reference for developing and implementing targeted interventions.
A cross-sectional study reported according to the STROBE checklist.
A convenience sample of 320 patients with breast cancer during rehabilitation was recruited from one hospital in China. Data were collected from April to August 2022 using a self-report questionnaire, including the demographic and clinical information, Appraisal of Self-Care Agency Scale-Revised, Multidimensional Scale of Perceived Social Support, Connor-Davidson Resilience Scale-10 item, and Patient Health Questionnaire-9. The mediation analysis was conducted using the SPSS Process macro.
Self-care ability was positively associated with social support (β = .229) and resilience (β = .290), and negatively associated with depression (β = −.208). The relationship between social support and self-care ability was mediated by resilience and depression, respectively, and together in serial. The multiple mediating effects accounted for 34.0% of the total effect of social support on self-care ability.
Our findings identify resilience and depression as multiple mediators between social support and self-care ability and highlight the important roles of social support, resilience and depression in improving self-care ability.
Healthcare providers should pay great attention to the underlying mechanisms of how social support affects patients' self-care ability during breast cancer rehabilitation. Integrated intervention programmes targeted at enhancing social support, building resilience and alleviating depression might be beneficial to the improvement of self-care ability.

The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist for cross-sectional studies was applied to report the results.
To examine chain mediating effect of discharge readiness and self-efficacy between quality of discharge teaching and self-management in patients after percutaneous coronary intervention (PCI).
Although self-management after PCI has significant benefits in controlling risk factors and delaying disease progression, the status of self-management remains unoptimistic. A large number of studies have explored the close relationship between the quality of discharge teaching and patients self-management, but little is known about the underlying mechanisms.
The cross-sectional samples was collected from a tertiary hospital in China. Self-reported questionnaires were used to assess quality of discharge teaching, discharge readiness, self-efficacy and self-management. Pearson correlation analysis and mediation effect analysis were used for statistical analysis.
The study used the STROBE checklist for reporting.
A total of 198 patients with a mean age of 64.99 ± 11.32 (34–85) were included. The mean score of self-management was 88.41 ± 11.82. Quality of discharge teaching, discharge readiness, self-efficacy and self-management were all positively correlated. Mediation effect analysis showed that the mediating effects of discharge readiness, self-efficacy, discharge readiness and self-efficacy between quality of discharge teaching and self-management were 0.157, 0.177 and 0.049, respectively, accounting for 21.96%, 24.76% and 6.85% of the total effect.
The quality of discharge teaching for patients after PCI not only directly affects self-management, but also can indirectly affect self-management through discharge readiness and self-efficacy.
To improve the life quality of patients after PCI, medical staff should pay attention to the influence of self-management of quality of discharge teaching, and develop intervention strategies based on the path of discharge readiness and self-efficacy.
Questionnaires filled out by patients were used to understand the association between quality of discharge teaching, discharge readiness, self-efficacy and self-management.
To map the commonly used quantitative blood loss measurement methods in clinical practice and provide a solid foundation for future studies.
This study adhered to the JBI methodology for scoping reviews and preferred reporting items for systematic reviews and meta-analyses extension for scoping reviews. We conducted a literature search using five databases to retrieve articles published between January 2012 and September 2022. The search was repeated on 29 February 2024. Data extraction and verification were carried out by two independent researchers using a self-designed data extraction form.
Ultimately, 26 studies published between 2012 and 2024 were considered eligible for inclusion. Six categories of methods were identified from the 26 articles. Among the included studies, only two involved randomized controlled trials, with the majority being observational studies. The World Health Organization (2012) version of the postpartum haemorrhage diagnostic criteria was predominantly used in most studies. Gravimetric and volumetric methods emerged as the most commonly used methods for quantifying postpartum haemorrhages. The timing of blood collection was inconsistent among the included studies. Only 12 studies mentioned measures for the management of amniotic fluid.
This scoping review supports the replacement of the visual estimation of blood loss with quantitative assessment methods. Supporting a specific assessment approach is not feasible due to the variability of the study. Future research should focus on establishing the best practices for specific quantitative methods to standardize the management of postpartum haemorrhage and reduce the incidence of postpartum haemorrhage-related adverse outcomes.
Healthcare professionals need to acknowledge the low accuracy of visual estimation methods and implement quantitative methods to assess postpartum blood loss. Given the limitations inherent in each assessment method, quantification of blood loss should be combined with assessment of maternal vital signs, physiologic indicators and other factors.
To explore older inpatients and their caregivers' care experience and how this relates to the gerontology care practice.
Research interest in the conceptualization of safe care for older inpatients was growing, and these studies were predominantly reported from a single or healthcare perspective. There is a shortage of literature on how patients and their caregivers conceptualise safe care.
Constructivist grounded theory.
Stage 1 included semi-structured interviews with inpatients. Stage 2 included semi-structured interviews with caregivers and six field notes. Purposive and theoretical sampling were used to recruit 61 participants across six healthcare institutions. Data analysis included initial coding, focused coding, and theoretical coding using constant comparative, field notes and memo writing.
The substantive theory to emerge from the data was A balance of unsafe care incidents and interactive cooperative care. This core concept was informed by four categories: unsafe care incidents, interactive cooperative care, person-centred care, contextual conditions, and one care outcome. The relationships between these categories constituted a balance in which patient-centred care was the core, unsafe care incidents were the barriers, interactive cooperative care was the facilitator, and the result of the balance was the care outcome. The balance constituted a safe care ecosystem under the interaction of contextual conditions.
Interactive cooperative care is vital in enabling care stakeholders to reduce unsafe care incidents, which facilitates them in achieving safe care and further constructing a healthy care ecosystem.
This theory identifies barriers and facilitators encountered by care stakeholders to cope with everyday problems and guides them in developing personalised care plans to ensure patient safety.
To investigate the prevalence of dysphagia in patients with COPD, identify the risk factors for dysphagia, develop a visual clinical prediction model and quantitatively predict the probability of developing dysphagia.
Patients with COPD are at high risk of dysphagia, which is strongly linked to the acute exacerbation of their condition. The use of effective tools to predict its risk may contribute to the early identification and treatment of dysphagia in patients with COPD.
A cross-sectional design.
From July 2021 to April 2023, we enrolled 405 patients with COPD for this study. The clinical prediction model was constructed according to the results of a univariate analysis and a logistic regression analysis, evaluated by discrimination, calibration and decision curve analysis and visualized by a nomogram. This study was reported using the TRIPOD checklist.
In total, 405 patients with COPD experienced dysphagia with a prevalence of 59.01%. A visual prediction model was constructed based on age, whether combined with cerebrovascular disease, chronic pulmonary heart disease, acute exacerbation of COPD, home noninvasive positive pressure ventilation, dyspnoea level and xerostomia level. The model exhibited excellent discrimination at an AUC of .879. Calibration curve analysis indicated a good agreement between experimental and predicted values, and the decision curve analysis showed a high clinical utility.
The model we devised may be used in clinical settings to predict the occurrence of dysphagia in patients with COPD at an early stage.
The model can help nursing staff to calculate the risk probability of dysphagia in patients with COPD, formulate personalized preventive care measures for high-risk groups as soon as possible to achieve early prevention or delay of dysphagia and its related complications and improve the prognosis.

The purpose of this study is to examine and evaluate the existing clinical practice guidelines and consensus statements regarding tracheostomy care for non-mechanically ventilated patients.
A systematic search of databases, and professional organisations was conducted from inception to 19 March 2023. Two appraisers evaluated each guideline using the Appraisal of Guidelines for Research & Evaluation II (AGREE II) and the Joanna Briggs Institute (JBI) Critical Appraisal Checklist for Text and Opinion Papers.
No specific clinical guidelines exist on airway management in non-mechanically ventilated patients. Of 6318 articles identified, we included 12 clinical practice guidelines, and 9 consensus statements, which were from China, the US, the UK, South Korea, Australia, France and Belgium. The AGREE II scores in six domains are (1) the scope and purpose, 70.30%; (2) stakeholder involvement, 37.61%; (3) rigor of development, 33.97%; (4) clarity of presentation, 68.16%; (5) applicability, 44.23% and (6) editorial independence, 40.06%. The overall quality of evidence was level B. The summarised recommendations for clinical practice encompass the following six areas: airway humidification, management of the trach cuff, management of inner cannula, tracheostoma care, tracheostomy suctioning and management and prevention of common post-operative complications.
The overall quality of the clinical guidelines on non-ventilated tracheostomy care was moderate, and further improvements are needed in domains of stakeholder involvement, applicability, clarity of presentation and editorial independence. Recommendations on non-ventilated tracheostomy care are often embedded in the guidelines on ventilated tracheostomy. Specific clinical guidelines are needed to provide a standardised approach to tracheostomy care for non-ventilated patients.
Patients with non-ventilated tracheostomy need specialised airway management. Improving patient outcomes requires standardised protocols, patient involvement, quality evaluation, and interdisciplinary approaches.
The study reviewed clinical practice guidelines and consensus statements, therefore patient or public input was not needed.
To describe a grading system that can be used to evaluate core competency of clinical nurse specialists (CNSs) at different levels.
Evaluate core competence of CNSs at different levels reflects the quality of nursing and the development of the nursing profession.
This research employed the Delphi method.
The STROBE checklist for observational cross-sectional studies was followed to report this research study. This study consisted of two main phases: a literature review and semistructured interviews. Individual semistructured interviews were conducted with 11 healthcare experts and two patients. Two rounds of questionnaire surveys were administered to 21 nursing experts using the Delphi method. The CNSs were classified as primary, intermediate or advanced based on their years of work, professional titles and educational qualifications.
The graded competency evaluation system consisted of five first-level indicators (clinical practice, consulting guidance and teaching, scientific research innovation, management and discipline development, and ethical decision-making), 15 second level indicators, and 40 third-level indicators. The authority coefficients (Cr) of the experts were .865 and .901. The Kendall's concordance coefficients of the three-level indicators were .417, .289 and .316 for primary CNSs; .384, .294 and .337 for intermediate CNSs; and .489, .289 and .239 for advanced CNSs.
The graded use evaluation system in clinical practice initially involves a comprehensive evaluation of the core abilities of CNSs. This is a tool for cultivating and grading the abilities of specialised nurses that can promote a practical upwards spiral.
The evaluation system can promote the scientific management and continuous improvement of CNSs in clinical nursing and can serve as a practical and objective reference for the effective management and development of CNSs.
Patients participated in the data collection process, during which they shared their health-seeking experience with our research team.
Early referral to palliative care has been viewed as providing opportunity for accomplishing end-of-life care goals of life closure, comfortable dying and effective grieving. However, previous studies have shown that palliative care referrals are being made too late. Healthcare providers play important role in helping terminally ill patients to early access and being referred to palliative care. It is necessary to understand healthcare providers' attitudes on palliative care referral and associated factors regarding referrals.
This review aimed to identify and synthesise healthcare providers' attitudes and associated factors on palliative care referrals systematically.
A systematic review of qualitative evidence and meta-aggregation was conducted and guided according to PRISMA guideline.
PubMed, CINAHL, PsycINFO, EMBASE, Web of Science and Cochrane databases from inception to 24 October 2022.
Database searches yielded 5856 references. Twenty-two studies met eligibility criteria and of moderate to high methodological quality were included. Studies occurred in USA, UK, Australia and France with 716 healthcare providers participants were included. A total of 378 codings were finally extracted and integrated into 41 categories, forming three synthesised findings: (1) Healthcare providers' attitudes towards palliative care referrals, (2) the influence of subjective norms on palliative care referral behaviour and (3) perceived behavioural control on palliative care referral behaviour.
This review demonstrates a series of factors that affect the palliative care referrals, including the attitudes of healthcare providers, the participation of patients and families, the support of colleagues and supervisors, inter-professional collaboration, the availability of hospice resource, disease trajectory and socio-economic factors. Further research that addresses these factors and design relevant trainings on improving healthcare providers' attitudes, enhancing patient and family engagement, strengthening support networks and optimising resource allocation may aid to meet increasing demands of patients.
This review not only guides healthcare providers in making better decisions about patient referrals by identifying and addressing barriers but also aids in the development of effective interventions that facilitate the early initiation of referrals.

To develop a predictive model for high-burnout of nurses.
A cross-sectional study.
This study was conducted using an online survey. Data were collected by the Chinese Maslach Burnout Inventory-General Survey (CMBI-GS) and self-administered questionnaires that included demographic, behavioural, health-related, and occupational variables. Participants were randomly divided into a development set and a validation set. In the development set, multivariate logistic regression analysis was conducted to identify factors associated with high-burnout risk, and a nomogram was constructed based on significant contributing factors. The discrimination, calibration, and clinical practicability of the nomogram were evaluated in both the development and validation sets using receiver operating characteristic (ROC) curve analysis, Hosmer–Lemeshow test, and decision curve analysis, respectively. Data analysis was performed using Stata 16.0 software.
A total of 2750 nurses from 23 provinces of mainland China responded, with 1925 participants (70%) in a development set and 825 participants (30%) in a validation set. Workplace violence, shift work, working time per week, depression, stress, self-reported health, and drinking were significant contributors to high-burnout risk and a nomogram was developed using these factors. The ROC curve analysis demonstrated that the area under the curve of the model was 0.808 in the development set and 0.790 in the validation set. The nomogram demonstrated a high net benefit in the clinical decision curve in both sets.
This study has developed and validated a predictive nomogram for identifying high-burnout in nurses.
The nomogram conducted by our study will assist nursing managers in identifying at-high-risk nurses and understanding related factors, helping them implement interventions early and purposefully.
The study adhered to the relevant EQUATOR reporting guidelines: TRIPOD Checklist for Prediction Model Development and Validation.

To explore barriers and facilitators that influence adherence to evidence-based guidelines for peripheral intravenous catheter care in different hospital wards.
Sequential explanatory mixedmethod study design, with qualitative data used to elaborate on quantitative findings.
Data were collected between March 2021 and March 2022 using the previously validated Peripheral Intravenous Catheter mini questionnaire (PIVC-miniQ) on each ward in a tertiary hospital in Norway. Survey completion was followed by individual interviews with nurses from selected wards. The Pillar Integration Process was used to integrate and analyse the quantitative and qualitative findings.
The PIVC-miniQ screening assessed 566 peripheral intravenous catheters in 448 patients in 41 wards, and we found variation between wards in the quality of care. Based on the quantitative variation, we interviewed 24 nurses on wards with either excellent or not as good quality. The integration of the quantitative and qualitative findings in the study enabled an understanding of factors that influence nurses' adherence to the care of peripheral venous catheters. One main theme and four subthemes emerged. The main finding was that ward culture affects education practice, and this was evident from four subthemes: (1) Deviation from best practice, (2) Gaps in education and clinical training, (3) Quality variation between wards and (4) The importance of supportive leadership.
This mixed method study is the first study to explore reasons for variability in peripheral intravenous catheter quality across hospital wards. We found that ward culture was central to catheter quality, with evidence of deviations from best practice correlating with observed catheter complications. Ward culture also impacted nursing education, with the main responsibility for learning peripheral intravenous catheter management left to students' clinical training placements. Addressing this educational gap and fostering supportive leadership, including champions, will likely improve peripheral intravenous catheter care and patient safety.
Nurses learn good peripheral intravenous catheter care in wards with supportive leaders and champions. This implies that the quality of nursing practice and patient outcomes are situational. Nurses need a strengthened emphasis on peripheral catheter quality in the undergraduate curriculum, and nurse leaders must emphasize the quality of catheter care in their wards.
The study findings impact nurse leaders who must commit to quality and safety outcomes by appointing and supporting local ward champions for promoting peripheral intravenous catheter care. This also impacts nursing education providers, as the emphasis on catheter care must be strengthened in the undergraduate nursing curriculum and continually reinforced in the hospital environment, particularly when guidelines are updated.
The study adhered to the Good Reporting of A Mixed Method Study (GRAMM).

While there exists an ample body of research in international contexts focused on the characterization and quantification of infertility psychological distress, the level of scholarly scrutiny directed towards this phenomenon within the context of China remains scant.
To investigate the formation and developmental processes of psychological distress associated with infertility and infertility treatment among women within the Chinese cultural context and to construct a theoretical framework that elucidates this phenomenon.
Qualitative approach with grounded theory methodology.
This study was conducted within the reproductive medicine department of a tertiary-level hospital located in central China from May to August 2023. Twenty-seven women who experienced infertility and underwent assisted reproductive treatment (ART) were interviewed. The interview sessions spanned durations ranging from 20 min to 1 h and 35 min. Data analysis included open coding, axial coding and selective coding. The study is reported using the COREQ checklist.
The infertility psychological distress experienced by women undergoing ART is a socially constructed phenomenon influenced by a dynamic interplay of forces that construct and conciliate it. The formation and progression of infertility psychological distress are rooted in the process of self-construction. A Middle-Ranged Theory titled ‘self-reconstruction under the dome of infertility and infertility treatment’ (SUDIT theory) was developed to explain this phenomenon. Within this framework, infertility psychological distress manifests across three distinct phases under the gambling of the constructive force and conciliative force: (1) distress of disrupting the former self; (2) distress linked to the struggling present self; and (3) the renewed-self harmonized with distress.
It is imperative for healthcare professionals and policymakers to acknowledge the socially constructed nature of infertility psychological distress, and proactively implement measures aimed at ameliorating it.

To investigate the prevalence of anxiety and depression symptoms in intensive care unit (ICU) patients with cardiovascular disease (CVD) and to explore which elements are risk factors for the development of anxiety and depression symptoms.
A cross-sectional study.
A total of 1028 ICU patients with CVD were enrolled in this cross-sectional study. Logistic regression was used to assess risk factors and associations between anxiety and depression symptoms, and mediation analysis was used to explore the effect of risk factors on the association between anxiety and depression symptoms. Reporting of the study followed the STROBE checklist.
The results showed that among ICU patients with CVD, 38.1% had anxiety symptoms, 28.7% had depression symptoms and 19.3% had both anxiety and depression symptoms, and there was a significant association between anxiety and depression symptoms. We also identified female gender, hypertension, hyperlipidemia and cardiac function class IV as independent risk factors for anxiety and depression symptoms. Importantly, these factors also mediated the association between anxiety and depression symptoms, emphasising their role in the psychological well-being of this patient group.
ICU patients with CVD were prone to anxiety and depression symptoms. Female gender, hypertension, hyperlipidemia and cardiac function class IV were identified as independent risk factors that also served as mediators in the relationship between anxiety and depression symptoms. Especially, cardiac function class IV emerged as a critical factor in this association.
It is imperative for critical care professionals to recognize the elevated risk of depression and anxiety among ICU patients with severe CVD, especially those with cardiac function class IV, hypertension, hyperlipidemia and females. Proactive and supportive measures are essential for this vulnerable group during their ICU stay to safeguard their mental health and prevent negative outcomes.

To map evidence of the existing virtual reality-based dementia educational programmes and the effects of these educational programmes on dementia formal and informal caregivers.
A scoping review.
A comprehensive search of nine databases was conducted to find studies from the inception of the databases to October 2023. Two authors independently screened the titles and abstracts related to the eligibility criteria. Full texts of potentially relevant studies were read by one author and checked by a second. Data extraction and synthesis using NVivo 12 were undertaken by one author and checked by two other authors.
Nineteen studies published between 2002 and 2022. The four randomised controlled studies and five qualitative studies were of moderate to good methodological quality. The 10 quasi-experimental studies were of weak to moderate quality. Fifteen virtual reality-based educational programmes had a positive influence on formal and informal caregivers, including improving caregivers' perceptions changing attitudes towards people with dementia, while the nursing competence of formal caregivers did not improve in short term. Educational programmes that covered dementia-related information and care strategies better improved the knowledge level of dementia formal and informal caregivers.
The qualitative and quantitative studies of moderate to good quality included in this study support the idea that virtual reality-based dementia educational programmes may be a safe and effective way and have potential benefits for improving knowledge, perceptions, attitudes and nursing competence.
This scoping review will provide an emerging teaching model for formal and informal caregivers of people with dementia and help them better understand the types and the influence of virtual reality-based dementia educational programmes.
PRISMA-ScR.
Not required as this review in accordance with the aim to map existing literature from the dementia formal and informal caregivers' perspective.

Triple-negative breast cancer (TNBC) demands urgent attention for the development of effective treatment strategies due to its aggressiveness and limited therapeutic options [1]. This research is primarily focused on identifying new biomarkers vital for immunotherapy, with the aim of developing tailored treatments specifically for TNBC, such as those targeting the PD-1/PD-L1 pathway. To achieve this, the study places a strong emphasis on investigating Ig genes, a characteristic of immune checkpoint inhibitors, particularly genes expressing Ig-like domains with altered expression levels induced by "cancer deformation," a condition associated with cancer malignancy. Human cells can express approximately 800 Ig family genes, yet only a few Ig genes, including PD-1 and PD-L1, have been developed into immunotherapy drugs thus far. Therefore, we investigated the Ig genes that were either upregulated or downregulated by the artificial metastatic environment in TNBC cell line. As a result, we confirmed the upregulation of approximately 13 Ig genes and validated them using qPCR. In summary, our study proposes an approach for identifying new biomarkers applicable to future immunotherapies aimed at addressing challenging cases of TNBC where conventional treatments fall short.
