Early detection of sacral pressure injuries (PIs) in immobilised polytrauma patients remains challenging. This study evaluated ultrahigh-frequency (UHF) ultrasound combining structural and haemodynamic parameters for early PI diagnosis. In a prospective cohort of 73 polytrauma patients (Injury Severity Score 16–25), daily sacrococcygeal assessments were performed over 15 days using UHF ultrasound (Mindray Resona 11; L20-5 s probe). Parameters included 2D morphology, perfusion (colour power angiography [CPA]), flow metrics (peak systolic velocity [PSV]), Braden Scale and inflammatory markers. PI incidence was 27.4% (n = 20; all stage I/II). Haemodynamic markers outperformed 2D ultrasound: CPA grade ≥ 1 (AUC = 0.858, 80.0% sensitivity) and PSV > 5.55 cm/s (AUC = 0.841, 95.0% sensitivity). Combined CPA + PSV achieved superior accuracy (AUC = 0.922). Systemic inflammation showed no intergroup differences. UHF ultrasound detects early PIs by capturing ischaemia-reperfusion changes. The CPA + PSV protocol provides nurses with a rapid (< 5 min), sensitive bedside tool to guide proactive interventions.
Lower extremity lymphedema (LEL) is a debilitating complication for patients with gynecologic cancer. A series of strategies have been recommended to mitigate the risk of LEL and improve patient outcomes; however, investigation into LEL risk management behaviours in this population is limited, and the absence of reliable and valid tools is an important reason.
To develop and evaluate the psychometric properties of the lower extremity lymphedema risk management behaviours questionnaire (LELRMBQ) for Chinese patients with gynaecologic cancer.
This was a methodological study.
Initial items were generated using a literature review. The initial LELRMBQ was refined, and its content validity was evaluated by conducting two rounds of expert consultation and a pilot study. Psychometric testing of 389 participants recruited by convenience sampling was conducted from December 2022 to June 2023. Exploratory factor analysis (EFA; subsample 1, N = 158) and confirmatory factor analysis (CFA; subsample 2, N = 231) were performed separately to determine the multi-dimensional structure of the questionnaire. Known-group validity, internal consistency reliability, and test–retest reliability were also evaluated.
A total of 25 items with satisfactory content validity were included in psychometric testing. The EFA identified a four-factor structure, comprising 18 items, which explained 74.49% of the total variance. The CFA supported this structure with acceptable fit indices. Known-group validity was partially supported by significant differences in total LELRMBQ scores among groups with different education levels, residence, cancer type, and LEL awareness. Internal consistency and temporal stability were acceptable.
The 18-item LELRMBQ demonstrated sufficient reliability and validity as a tool for measuring LEL risk management behaviours in patients with gynaecologic cancer.
The LELRMBQ has potential applicability in assessing LEL risk management behaviours, identifying gaps in educational practices, tailoring effective interventions, and evaluating intervention effectiveness.

IntroductionGiven the high recurrence rate of bladder cancer (BCa) and the significant adverse effects associated with conventional treatments, it is urgent to search for new clinical therapeutic targets and safer natural-derived compounds. Resveratrol (Res) has been demonstrated to exhibit cytotoxicity against various tumors. However, the signaling pathways and targets involved in inhibition of BCa cells still need further exploration. This study aims to investigate the mechanism of Res in Bca via suppression of the AURKA/STAT3 axis, providing important theoretical basis for subsequent further researches on Res for treating BCa.
MethodsDifferentially expressed genes were identified through bioinformatics methods and the binding sites of resveratrol were also identified. The cell survival rate was detected by the CCK8 method to calculate the concentrations of Res for 30% inhibition and for 50% inhibition. Then, flow cytometry was used to detect the cell cycle and apoptosis after treatment with different concentrations of Res. Immunofluorescence staining was used to detect the effects of Res and MLN8237 on the expression of STAT3. Western blot and qPCR analyses were used to verify the reliability of the effects of Res and MLN8237 on target proteins.
ResultsAURKA was identified as the potential target of Res by computational analysis. Further validation through CCK8 assays and flow cytometry demonstrated that Res could inhibit BCa cells and their cell cycle in a time- and dose-dependent manner. Immunofluorescence staining revealed both Res and MLN8237 suppressed STAT3 expression in BCa cells. Additionally, western blot and qPCR analysis confirmed that Res and MLN8237 inhibited the expression of AURKA and known target genes (VEGF, Bcl-2, and Cyclin D1).
ConclusionOur findings suggest that Res may regulate BCa cell expression through the AURKA/STAT3 axis, providing a theoretical foundation for the structural optimization of Res and the development of multi-target drugs for clinical application.
To assess the effectiveness, process, and economic outcomes of integrated care for community-dwelling frail older adults.
A systematic review and meta-analysis.
We searched nine databases, including PubMed, Web of Science, CINAHL, Embase, the Cochrane Library, CNKI, SinoMed, Wanfang, and VIP, three trial registers, grey literature, and reference lists up to April 2024, with an updated search in March 2025.
Randomised controlled trials and non-randomised studies of interventions involving integrated care for community-dwelling frail older adults were included. Data analysis was conducted using the Comprehensive Meta-Analysis software.
This review included 12 studies involving 6819 community-dwelling frail older adults from high-income regions. The results indicated that integrated care had significantly positive effects on frailty and functional ability, but not on social function, hospitalisation, nursing home admission, quality of life, and mortality. Outcomes of caregivers and professionals were rarely reported. The cost-effectiveness of integrated care has not been confirmed by limited evidence. Few studies have adopted a systematic approach to designing and conducting comprehensive process evaluations guided by scientific frameworks.
Integrated care improves frailty and functional ability in community-dwelling frail older adults but lacks consistent benefits for other outcomes. The lack of evidence on cost-effectiveness and the caregiver and professional outcomes highlight critical gaps in current research. The absence of systematic process evaluations underscores the need for future studies to adopt rigorous frameworks to assess them.
This implicates that more research, particularly in underserved regions that lack a high standard of usual medical services, should emphasise the outcomes of caregivers and healthcare professionals, process evaluation, and health economics. Policymakers and practitioners must consider these gaps when implementing integrated care programmes to ensure equitable and sustainable healthcare solutions.
