BackgroundTo alleviate pain in burn patients during dressing changes, it is necessary to identify an effective analgesic method. Conventional opioid analgesics have many limitations. Nitrous oxide is a fast-acting, safe and reversible inhaled analgesic gas. This systematic review will evaluate the effectiveness and safety of nitrous oxide in the treatment of pain during dressing changes in burn patients.
MethodThe protocol was developed according to the PRISMA-P checklist and registered on PROSPERO (CRD42024550197). A systematic search will be performed in the following databases: PubMed, EMBASE, Web of Science, Cochrane Library to identify clinical trials comparing nitrous oxide inhalation with standard care in pain management during dressing changes in burn wounds. The search of all databases will be conducted on October 15, 2025.Our search scope will include studies published between each database creation and search date.Two researchers will independently screen studies, extract data, and evaluate study quality using the Risk of Bias2 tool. Primary outcomes will include pain, anxiety, side effects, among others.R statistical software (version 4.3.1) and R studio will be used to perform meta-analyses.Effect size will be expressed by 95% confidence interval (Cl) of weighted mean difference (MD) and risk ratio (RR). Subgroup analyses and sensitivity analyses will be performed to explore sources of heterogeneity and assess the robustness of the results.Publication bias will be assessed using funnel plot and Egger test. We will use the Grading of Recommendation, Evaluation, Development and Evaluation (GRADE) to assess the quality of the evidence.
DiscussionOperative pain has always been a difficult problem for burn patients. This study will evaluate the analgesic effect of nitrous oxide on dressing change in burn patients through comprehensive search and rigorous methods, and provide evidence support for clinical decision-making.

PurposeTo evaluate whether posterior column screws penetrate the posterior cortical surface of the acetabulum when assessed using obturator oblique radiographic imaging.
MethodsComputed tomography (CT) scans were performed on the right acetabulum of 50 healthy adults to measure the angle (α) between the posterior wall of the acetabulum and the sagittal plane at the level of the femoral head’s maximal diameter. In addition, five cadaveric pelvises were subjected to C-arm fluoroscopic imaging. A 6 cm long, 1.5 mm Kirschner wire was positioned along the posterior surface of the acetabular posterior column, aligned with the greater sciatic notch, and imaged in both the 45° and α-degree obturator oblique views. The radiographic line visualized from the Kirschner wire in the obturator oblique view was defined as the posterior iliac line, and its anatomical relationship with the posterior surface of the posterior column was analyzed. Subsequently, a 2.5 mm Kirschner wire was inserted into the posterior column at the standard entry point for screw placement using an electric drill, with the wire tip intentionally positioned between the posterior iliac line and the posterior rim in the 45° obturator oblique view. The trajectory of the wire was assessed under both 45° and α-degree obturator oblique views to determine its relation to the osseous corridor.
ResultsThe measured angle between the posterior surface of the acetabular posterior column and the sagittal plane was (60.2 ± 2.5)°. In the 45° obturator oblique view, the posterior iliac line corresponded with the outer edge of the iliac crest superiorly and the outer edge of the ischium inferiorly, while the posterior wall was projected posterior to the midpoint of the posterior iliac line. In the α° obturator oblique view, the posterior iliac line maintained this alignment but intersected centrally with the posterior acetabular wall. The 2.5 mm Kirschner wire remained within the osseous corridor under the 45° view but potentially extended beyond it under the α° view.
ConclusionWhen the posterior column screw is visualized posterior to the posterior iliac line in the 45° obturator oblique view, further assessment using a α° view is necessary. If the screw appears anterior to the posterior iliac line in the α° view, it indicates that the posterior cortical surface has not been breached.
To explore the illness coping experiences of patients with moderate-to-severe burns and provide a reference for healthcare professionals to formulate coping strategies.
Qualitative study using a descriptive phenomenological approach.
From 1 June to 30 September 2024, semi-structured interviews were conducted with 19 patients with moderate-to-severe burns. Colaizzi's seven-step method was used for data analysis.
Seven subthemes and three higher order themes were identified: (1) perception of illness experience; (2) coping with disease threats; and (3) benefits of coping with illness. Most of the participants faced multiple difficulties in their disease experiences, such as increased financial pressure, higher pressure on family caregiving, deformed physical conditions and negative emotions. Positive psychological qualities, family and social support played significant roles in coping with these challenges.
Patients with moderate-to-severe burns experience multiple difficulties during their recovery. Effective coping resources can help them overcome these challenges.
Healthcare professionals should work with patients with moderate-to-severe burns and their families to establish an effective support system that enhances patients' coping abilities and promotes their overall recovery.
Patients with moderate-to-severe burns face diverse challenges. However, their experiences and coping processes during recovery remain unclear. This study provided valuable insights into their illness experiences and coping strategies. The findings highlighted multiple difficulties, such as a significant increase in financial pressure and dependence on family caregiving, painful and deforming physical conditions and various negative emotions. Positive psychological qualities, family and social support play an important role in coping with these challenges. Healthcare professionals should work with patients and their families to establish effective support systems to promote overall recovery.

To systematically review published studies on the post stroke delirium risk prediction models; and to provide the evidence for developing and updating the clinically available prediction models.
Systematic review.
Systematically searched studies on 10 databases, which were conducted from inception to 9 January 2025. The studies of post-stroke delirium risk prediction models were included.
Extracted the data from the selected studies. The Prediction Model Risk of Bias Assessment Tool checklist was used to evaluate the risk of bias of the models. The meta-analysis of model performance and common predictors was performed by Revman 5.4 and Medcalc.
A total of 12 studies were included, and 21 risk prediction models for post-stroke delirium were constructed. The combined effect size of area under the receiver operating characteristic curve was 0.84. All studies were found to have a high risk of bias and good applicability. Meta-analysis showed: National Institutes of Health Stroke Scale score, age, neutrophil-to-lymphocyte ratio, neglect, visual impairment and atrial fibrillation were independent predictors of post-stroke delirium.
The included studies all found to have a high risk of bias; future studies should focus on adopting more scientifically rigorous study designs and following the standardised reporting guidelines to enhance extrapolation and facilitate its clinical application.
This review may promote clinical healthcare workers to develop and update clinically available prediction models, thereby establishing risk prediction models with strong clinical utility.
This study presents the first systematic evaluation of delirium risk prediction models in stroke patients, thereby facilitating the choice, use and develop of the clinical usable post stroke delirium risk prediction models.
This review adhered to the PRISMA guidelines.

To classify the unmet integrated care needs of older adults with multimorbidity and to explore the factors associated with different categories of unmet integrated care needs among the target population.
A cross-sectional survey using the statistical method of latent profile analysis.
From July 2022 to March 2023, 397 older adults with multimorbidity, aged 60 years or older, were recruited from one primary healthcare setting and from four secondary and tertiary hospitals to participate in face-to-face questionnaire surveys. The questionnaire used in this study to assess unmet integrated care needs among older adults with multimorbidity was self-designed through a series of steps, including a scoping review, expert consultation and cognitive interviews. Latent profile analysis was applied to uncover distinct profiles of unmet integrated care needs, and multinomial logistic regression was employed to explore whether the profiles were further distinguished by participants' sociodemographic and health-related covariates. The data were analysed using IBM SPSS v.29.0 and Mplus v.8.0.
The optimal solution was a four-profile model, characterised by high unmet integration needs, high unmet system integration needs, low unmet system integration needs and low unmet integration needs, respectively. Multinomial logistic regression results indicated that profile differences were associated with place of residence, number of coresidents and the presence or absence of complex multimorbidity.
The integrated care needs of older adults with multimorbidity have not yet been fully met. Classifying and characterising unmet integrated care needs profiles is a crucial step in the rational allocation of integrated care resources.
This study was reported based on the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) for cross-sectional studies.
All participants were older adults with multimorbidity, and they were informed that they could withdraw from the study at any time.
Pressure injury (PI) is common in the ICU and not well captured by single-risk tools such as the Braden scale. We aimed to develop and internally validate a machine-learning model to predict new-onset PI using routinely collected ICU data. This retrospective single-centre cohort included adult ICU patients with length of stay ≥ 48 h (2018–2023). The primary outcome was new-onset PI during ICU stay. Candidate predictors were pre-specified: minimum albumin, maximum lactate, SOFA, APACHE II, first recorded Braden score, age, BMI, a nutrition score and treatment indicators. Missing values were imputed (median/mode). A gradient boosting model (GBM) was evaluated with stratified 3-fold cross-validation; a random forest (RF) served as a benchmark (stratified 70/30 train–test split). Discrimination (AUC) was primary; calibration, Brier score, decision-curve analysis (DCA) and feature importance were secondary. Logistic regression quantified independent associations. Among included ICU stays, 14.6% developed PI. On multivariable analysis, higher lactate, lower albumin, lower Braden scores, older age, CRRT, prone positioning, enteral nutrition and analgesic exposure were associated with increased PI risk, whereas sedatives showed an inverse association. The GBM achieved AUC≈0.69 with acceptable calibration and net clinical benefit across thresholds commonly used in preventive workflows (≈0.10–0.50). Single markers or simple combinations displayed only modest discrimination. A GBM built from routine ICU data provided moderate, well-calibrated discrimination for predicting new-onset PI and demonstrated decision-relevant net benefit. The model can complement Braden-based screening by refining risk stratification and prioritising intensified prevention for patients most likely to benefit. External validation and prospective evaluation are warranted.

DNA damage-induced by radiotherapy is a critical factor in promoting the death of colorectal cancer cells (CRC). Although high mobility group box 1 (HMGB1) reportedly plays a vital role in tumor radioresistance by modulating DNA damage repair, the precise mechanisms remain unclear. In this study, HMGB1 knockdown markedly enhanced cell apoptosis after radiation. HMGB1 downregulation significantly inhibited DNA damage repair and reactive oxygen species (ROS)-mediated redox homeostasis after irradiation in CRC cells. Mechanistically, HMGB1 interacts with KU70 via its region spanning residues 95–163. This interaction subsequently activates the non-homologous end joining (NHEJ) pathway to facilitate DNA damage repair, ultimately leading to reduced radiation-induced cell apoptosis. KU70 silencing showed the same effect as HMGB1 depletion mediated cell apoptosis and DNA damage response both in vitro and in vivo. Additionally, HMGB1 and KU70 were overexpressed in CRC tissues. Analysis of the GEPIA database indicated that elevated levels of both genes showed a trend toward association with poor patient prognosis, although this did not reach statistical significance. The current study revealed that HMGB1 may promote DNA damage repair through KU70 and its mediated NHEJ pathway to affect apoptosis in CRC cells after irradiation. Thus, targeting the HMGB1/KU70/NHEJ axis may be a potential therapeutic target to promote the response of CRC to radiotherapy and in-depth study of the specific mechanism of this axis in CRC radioresistance will help to the develop more effective treatment strategies.To explore the complex relationships among non-suicidal self-injury, depression and anxiety symptoms in adolescents, identify key symptoms and provide a theoretical foundation for targeted interventions.
A cross-sectional study.
In total, 1126 adolescents from a tertiary hospital in Shandong Province were assessed using the Adolescent Self-Injury Questionnaire, Patient Health Questionnaire and Generalised Anxiety Disorder Scale. Network analysis was employed to construct symptom networks and identify central and bridging symptoms.
The network analysis revealed that nodes GAD5 (Restlessness), GAD2 (Uncontrollable worry), and GAD4 (Trouble relaxing) exhibited the highest centrality indices, establishing them as core symptoms within the overall symptom network. The highest bridge intensity nodes were GAD1 (Nervousness), GAD5 (Restlessness) and non-suicidal self-injury.
By accurately identifying core and bridging symptoms, a scientific foundation is provided for developing precise and effective symptom management plans.
The study identified the most influential nodes in anxiety and depression among adolescents with non-suicidal self-injury. The findings would help in carrying out personalised and precise interventions to reduce non-suicidal self-injury occurrence and alleviate anxiety and depression symptoms among adolescents.
This study adheres to the STROBE guideline of reporting.
This study did not include patient or public involvement in its design, conduct or reporting.
To analyse the current status of psychological resilience in Parkinson's disease (PD) patients and its correlation with social support and coping style.
A cross-sectional study.
PD patients hospitalized in a tertiary-level hospital in Shijiazhuang, Hebei Province, from March 2022 to March 2023 were selected for the study using the convenience sampling method. A general information questionnaire, psychological resilience scale, Medical Coping Modes Questionnaire and Perceived Social Support Scale were used to investigate 111 cases of PD. SPSS 25.0 software was used for statistical analysis. The data were analysed using independent samples t-test, one-way ANOVA, multiple linear regression analysis and the Pearson correlation coefficient.
Parkinson's disease patients have a moderate level of psychological resilience. The results of the Pearson correlation analyses showed that the level of psychological resilience was positively correlated with social support and confrontation and was negatively correlated with avoidance and acceptance-resignation. The results of multiple linear regression analysis showed that social support and acceptance-resignation were the influencing factors of psychological resilience in PD patients.
The psychological resilience of PD patients is at a moderate level. Social support and acceptance-resignation are the factors influencing the psychological resilience of PD patients.
This study analysed the level of psychological resilience in PD patients and its correlation with social support and coping style from the perspective of positive psychology to provide some reference for targeted clinical interventions. Our study found that social support and acceptance-resignation are influential factors in psychological resilience in PD patients. Medical staff should encourage patients to face the disease positively and their social support should be increased in order to improve their level of psychological resilience.

Cough, a prevalent and debilitating symptom of lung cancer, remains poorly managed. Accumulating evidence on non-pharmacological interventions for lung cancer cough necessitates systematic evaluation to assess their efficacy.
To synthesise evidence on non-pharmacological interventions for managing cough in lung cancer patients.
A systematic review and meta-analysis following the Preferred Reporting Items for Systematic reviews and Meta-Analyses reporting guideline.
Nine databases were searched from inception to December 2024 to identify randomised controlled trials. Study quality was appraised using the Revised Cochrane Risk-of-Bias Tool for Randomised Trials. Meta-analyses were performed for quantitative synthesis, with sources of heterogeneity examined using meta-regression and subgroup analyses.
Thirty-eight studies representing 2995 lung cancer patients were identified. These studies investigated acupuncture therapy, moxibustion, pulmonary rehabilitation, self-management intervention, physical exercises, psychoeducation support, mindfulness, and multicomponent interventions. Non-pharmacological interventions showed positive effects on cough severity and cough-related quality of life. Additional benefits were observed for expectoration, dyspnea, and general quality of life. Pulmonary rehabilitation showed a greater effect on cough severity than other non-pharmacological interventions.
Non-pharmacological interventions are promising in improving cough, expectoration, dyspnea, and general quality of life among lung cancer patients. Pulmonary rehabilitation showed the most promising effect. Future research should adopt objective cough measures in addition to self-reported measures.
Non-pharmacological interventions demonstrated potential effects in relieving cough and additional benefits in improving expectoration, dyspnea, and general quality of life among lung cancer patients. Healthcare professionals may adopt pulmonary rehabilitation for cough and related symptoms in lung cancer patients.
As the first meta-analysis addressing non-pharmacological interventions for lung cancer cough, this study provides evidence supporting their clinical efficacy for improving cough and associated symptoms among patients with lung cancer.

PROSPERO CRD42024588729.
This study aimed to translate the Nurse Prescribing Self-Efficacy Scale (NP-SES) into Chinese and evaluate its reliability and validity.
A systematic methodological framework was used.
The study’s setting was hospitals and nursing schools in Jiangsu province, China.
A convenience sample of 309 practising nurses and nursing graduates was recruited.
The reliability and validity of the scale were assessed. Item screening was based on critical ratio values and item–total correlation coefficients. Validity was evaluated through content validity, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Internal consistency was assessed using Cronbach’s α coefficient and split-half reliability.
EFA identified three common factors, accounting for 78.608% of the total variance. CFA indicated that model fit indices met acceptable thresholds, supporting the scale’s structural validity. Cronbach’s α and split-half reliability for subdimensions ranged from 0.907 to 0.957 and from 0.867 to 0.944, respectively.
The Chinese version of the NP-SES demonstrates good reliability and validity and is suitable for assessing clinical nurses’ self-efficacy in prescribing.
Turnover intention among nurses poses a significant threat to both workforce stability and the overall quality of healthcare delivery. However, few studies have comprehensively examined the associations between turnover intention and nurses' individual and team-level resources within a multilevel framework. Our study aims to provide an in-depth exploration of the relationship between turnover intention and nurses' individual and team-level resources.
The multicenter cross-sectional study adopted a stratified convenience sampling approach to enroll 773 clinical nurses from 62 teams across eight hospitals in Shandong Province, China.
We used the 10-item Connor-Davidson Resilience Scale for psychological resilience, the Perceived Social Support Scale for perceived social support, the 51-item Analyzing and Developing Adaptability and Performance in Teams to Enhance Resilience Scale for team resilience, and a single-item turnover intention measure. Multilevel logistic regression modeling was conducted to examine the simultaneous impacts of individual-level (psychological resilience and perceived social support) and team-level (team resilience) factors on turnover intention, while controlling for key demographic and organizational covariates.
The multilevel analysis revealed several key findings: (1) The prevalence of turnover intention reached 35.6%, indicating a substantial workforce stability challenge; (2) Multilevel modeling demonstrated significant between-team variance (ICC = 0.19), confirming the importance of examining nested data structures; (3) At the individual level, both psychological resilience (OR = 0.78, CI: 0.62–0.99) and perceived social support (OR = 0.75, CI: 0.60–0.94) showed significant negative associations with turnover intention; (4) At the team level, higher team resilience predicted lower turnover intention (OR = 0.73, CI: 0.56–0.94). These results were obtained after controlling for key demographic and organizational covariates, highlighting the robust protective effects of multilevel resources against nurses' turnover propensity.
The prevalence of turnover intention was relatively high in this study. Nurses with higher psychological resilience, perceived social support, and team resilience exhibited lower turnover intention. Healthcare administrators need to increase investments in nurses' multilevel resources to stabilize the nursing workforce and ensure the sustainability of the healthcare system.
Understanding the multi-level factors influencing nurses' turnover intention can help nursing managers develop targeted strategies from multiple perspectives in clinical settings, thereby reducing nurses' turnover intention.
To analyse current Glasgow Coma Scale practice among emergency nurses in China and identify factors influencing assessment quality.
A quantitative, multicenter cross-sectional design.
A convenience sample of 1740 emergency nurses from secondary and tertiary hospitals across 21 provinces completed a validated structured questionnaire between March and April 2025. Participants had at least 6 months of emergency nursing experience. Data analysis included descriptive statistics, chi-square tests, and multiple logistic regression to examine factors influencing correct Glasgow Coma Scale application.
Participants had a mean age of 29.8 years (SD = 6.2). Only 52.5% of nurses demonstrated correct Glasgow Coma Scale application despite 97.0% having theoretical knowledge of scoring criteria. While 56.8% had received Glasgow Coma Scale training, significant standardisation deficiencies emerged. Notably, 41.8% of departments lacked operational guidelines, and 53.7% of nurses experienced scoring disagreements with colleagues. Clinical utilisation varied substantially by patient population: traumatic brain injury (97.8%), neurological diseases (96.9%), and systemic critical illness (85.8%). Multivariate analysis identified six significant factors influencing correct application: standardised training (OR = 2.252, 95% CI: 1.789–2.825), manageable workload ≤ 4 patients/shift (OR = 1.652, 95% CI: 1.327–2.057), departmental guidelines (OR = 1.523, 95% CI: 1.233–1.881), extensive work experience ≥ 9 years (OR = 1.534, 95% CI: 1.182–1.992), while multidisciplinary collaboration issues (OR = 0.559, 95% CI: 0.439–0.712) and special patient experience (OR = 0.520, 95% CI: 0.406–0.666) were associated with reduced accuracy.
Substantial standardisation challenges exist in Glasgow Coma Scale practice among Chinese emergency nurses, characterised by significant gaps between theoretical knowledge and clinical application. Major barriers include insufficient standardised guidelines, inconsistent training approaches, and inadequate interdisciplinary collaboration.
Healthcare administrators should develop national standardised guidelines, implement simulation-based training programs, optimise emergency workflows, and integrate alternative assessment tools to enhance consciousness assessment accuracy and improve patient safety.

Intensive care unit (ICU) visiting restrictions in hospitals, implemented due to infection control and other factors, limited contact between patients and family members, affecting patients’ well-being and clinical outcomes. With the evolution of voice-cloning based on artificial intelligence (AI) technology, it has become possible for health providers to communicate with critically ill patients using highly similar synthetic voices of their loved ones during ICU care. This current randomised, controlled trial will explore the effect of voice-cloning care on improving mental health outcomes for critically ill patients, with ICU-acquired anxiety as the primary indicator.
This study will enrol 234 adult ICU patients, who are expected to require mechanical ventilation for over 24 hours and an ICU stay exceeding 72 hours. Participants will be randomly assigned to two groups. The control group will receive standardised communication as part of usual ICU care, while the intervention group will receive Speech-to-Speech Voice-Cloning Care (SVCC) in addition to standard ICU care. The SVCC interventions involve nurses using a participant’s family member’s cloned voice to deliver pre-set communication scripts during awakening, soothing and preparation for endotracheal tube removal. The primary outcome is expected to lead to improvements in ICU-acquired anxiety for the intervention group, measured by the Hospital Anxiety and Depression Scale. Secondary outcomes include ICU-acquired depression, the incidence of delirium, the mean duration of mechanical ventilation and the average length of ICU stay.
This protocol was approved by the Ethics Committee of Peking Union Medical College Hospital (Approval Number: K-6842). The protocol version number is 1.2 and the version date is 8 October 2024. Study findings will be disseminated through peer-reviewed publications and presentations at national and international conferences.

This study aims to explore the views and experiences of people with dementia, informal caregivers and professionals regarding eating and drinking difficulties.
A qualitative systematic review was conducted.
The Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines were used to conduct this systematic review. The quality of the included studies was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Qualitative Research, and the data were thematically synthesised using Thomas and Harden's three-stage method.
Six electronic databases (PubMed, EMBASE, Cochrane Library, Web of Science, CINAHL and PsycINFO) were searched from their respective inception dates to August 2025 to identify relevant studies.
Thematic analysis of the 16 included studies identified four key themes: (1) Physiological and psychological changes in people with dementia and caregivers; (2) factors influencing eating and drinking in people with dementia; (3) needs and recommendations for people with dementia, informal caregivers and professionals; (4) selection of eating methods for end-stage people with dementia.
Eating and drinking difficulties affect the well-being of both patients and caregivers. A good dining environment improves mealtime pleasure but demands caregivers' time and energy. All parties emphasised the importance of effective communication. In end-stage dementia, professional assistance is crucial for enteral nutrition decisions.
Collaboration among patients, caregivers and professionals is vital for creating tailored nutritional plans and improving mealtime environments, thereby enhancing nutritional intake. In advanced dementia, providers must provide balanced information on comfort feeding versus enteral nutrition to aid decision-making.
What problems were addressed in this study? This study addressed the lack of a consolidated, tri-perspective understanding of eating and drinking difficulties in dementia care settings. What are the main findings? Four key themes were identified: physiological and psychological changes, influencing factors, stakeholder needs and end-of-life decision-making. Where and on whom will the research have an impact? This will impact care practices for people with dementia and inform the training and support of informal caregivers and healthcare professionals.

BackgroundDiethyl phthalate (DEP), a widely used plasticizer with endocrine-disrupting properties, has raised concerns regarding its potential carcinogenic effects. However, its precise role in colorectal cancer (CRC) development remains poorly understood.
MethodsThe chemical structure of DEP was obtained from the PubChem database. Potential targets of DEP were identified through ChEMBL and STITCH databases and intersected with known CRC-related genes to screen for candidate biomarkers. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed to explore the biological functions and signaling pathways involved. Molecular docking was conducted to predict the binding affinities between DEP and core targets. Finally, 200-ns molecular dynamics (MD) simulations using GROMACS were employed to evaluate the binding stability and dynamic behavior of the DEP–target complexes.
ResultsA total of 62 overlapping genes were identified between DEP targets and CRC-associated genes. GO and KEGG enrichment analyses indicated enrichment in epigenetic regulation, chromatin remodeling, and cancer-related signaling pathways, including Notch, TGF-β, and FoxO. Protein–protein interaction analysis identified EP300, EZH2, HDAC1, HDAC2, and KDM1A as key epigenetic regulators. Molecular docking predicted moderate binding affinities between DEP and these targets (−6.6 to −5.7 kcal·mol ⁻ ¹). Subsequent 200-ns MD simulations suggested that DEP formed stable complexes with HDAC1, KDM1A, and EZH2, moderate stability with EP300, and partial dissociation with HDAC2, consistent with hydrophobic and hydrogen-bonding interactions at the binding interfaces.
ConclusionThis study provides a theoretical framework for exploring the molecular mechanisms through which DEP may contribute to CRC development, emphasizing the value of network toxicology in cancer research. These findings may inform future investigations into the risks of DEP exposure and support public health policy and the development of targeted therapeutic strategies.
To explore the relationship between sleep and cognitive frailty in older adults.
A systematic review and meta-analysis.
The Web of Science, Cochrane Library, CINAHL, Embase, PsycINFO and PubMed databases were searched from inception to October 28, 2024.
Two investigators independently conducted literature screening, data extraction and quality assessment. The Joanna Briggs Institute Critical Appraisal Tool and Newcastle–Ottawa Scale were used to evaluate methodological quality. This review followed PRISMA guidelines.
This review included 13 articles involving 14,223 individuals, and 10 studies included in the meta-analysis. Across 13 studies, the overall prevalence of cognitive frailty was 25%. Sleep problems were categorised into four categories; the results reported that poor sleep quality, long sleep time and insomnia were correlated with the presence of cognitive frailty. However, the relationship between short sleep time and cognitive frailty was not significant.
This review quantitatively suggested that sleep parameters such as long sleep time, insomnia and poor sleep quality were correlated with the presence of cognitive frailty. Future research should adopt longitudinal designs and use validated instruments to measure both quantitative and qualitative aspects of sleep, thereby facilitating a thorough examination of the strength of the relationship between sleep and cognitive frailty, as well as the direction of causality.
The review highlights the need to integrate comprehensive sleep assessments and targeted interventions into nursing care plans for older adults to enhance their sleep health. The findings will provide support for the development of effective interventions to prevent and manage cognitive frailty in the older population.
