Chronic heart failure (CHF) is a progressive life-limiting condition that necessitates early implementation of advance care planning (ACP). However, patients and caregivers encounter emotional, informational, and cultural barriers to effective ACP engagement. This meta-synthesis consolidates qualitative evidence to deepen our understanding of ACP practices in CHF care.
This study aimed to explore experiences of CHF patients and their caregivers in ACP, which is defined as a proactive decision-making process to establish future treatment plans based on patients' values. The study also aimed to identify barriers and facilitators influencing ACP decisions and assess the impact of flexible, personalized ACP approaches on care quality.
Using qualitative meta-synthesis, we analyzed 10 qualitative studies on CHF patients' and caregivers' ACP experiences. Data were thematically synthesized to identify emotional, relational, and practical factors that influence engagement in ACP.
Three themes emerged: (1) heart failure patients and caregivers face difficulties in ACP (difficulties from patients, difficulties from the family, and difficulties from the society), (2) multidimensional drivers and impacts of ACP (advance care planning drivers, acceptance and implementation of ACP, emotions and effects of ACP), (3) flexible, personalized ACP delivers tangible benefits (timing and effectiveness of ACP discussions, patients and caregivers have personalized needs for ACP, and patients and caregivers affirm ACP benefits).
ACP plays a critical role in improving end-of-life care quality and reducing emotional and decision-making burdens on caregivers. Flexible and personalized ACP strategies supported by trained healthcare professionals more effectively meet the unique needs of patients and families. To overcome persistent barriers and promote broader ACP adoption, healthcare systems should prioritize provider communication training, ACP education, and support systems tailored to diverse cultural contexts.

PurposeThis study aims to develop a fully automated VMAT planning program for short-course radiotherapy (SCRT) in Locally Advanced Rectal Cancer (LARC) and assess its plan quality, feasibility, and efficiency.
Materials and methodsThirty LARC patients who underwent short-course VMAT treatment were retrospectively selected from our institution for this study. An auto-planning program for neoadjuvant short-course radiotherapy (SCRT) in LARC was developed using the RayStation scripting platform integrated with the Python environment. The patients were re-planned using this auto-planning program. Subsequently, the differences between the automatic plans (APs) and existing manual plans (MPs) were compared in terms of plan quality, monitor units (MU), plan complexity, and other dosimetric parameters. Plan quality assurance (QA) was performed using the ArcCHECK dosimetric verification system.
ResultsCompared to MPs, the APs achieved similar target coverage and conformity, while providing more rapid dose fall-off. Except for the V5Gy dose level, other dosimetric metrics (V25 Gy, V23 Gy, V15 Gy, Dmean, etc.) for the small bowel were significantly lower in the AP compared to the MP (p Conclusion
We developed a fully automated, feasible SCRT VMAT planning program for LARC. This program significantly enhanced plan quality and efficiency while substantially reducing the dose to OARs.

ObjectiveEvidence suggests that nephrolithiasis and hyperlipidemia are linked. The study is designed to identify diagnostic biomarkers for nephrolithiasis in conjunction with hyperlipidemia using bioinformatics analysis, while exploring the potential common denominator pathogenesis.
MethodsThe NCBI Gene Expression Omnibus (GEO) database provided separate datasets for nephrolithiasis and hyperlipidemia. We employed the R limma package to detect differentially expressed genes (DEGs), which were subsequently analyzed for enrichment using Gene Set Enrichment Analysis (GSEA), Gene Ontology (GO), and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. Immune cell infiltration was analyzed by the CIBERSORT method. The WGCNA-R package clustered genes with similar expression profiles, followed by an analysis of the associations between the modules and specific traits or phenotypes. The STRING database was utilized to establish a protein-protein interaction (PPI) network and key functional modules, which were then analyzed using Cytoscape software. Diagnostic genes for both diseases were screened from core hub genes using least absolute shrinkage and selection operator (Lasso) regression. Subsequently, we generated receiver operating characteristic (ROC) curves to validate the predictive ability of these diagnostic genes for diagnosing nephrolithiasis in combination with hyperlipidemia. Lastly, the Network Analyst platform facilitated the construction of transcription factor-gene (TF-gene) and TF-miRNA regulatory networks.
ResultsBased on datasets of nephrolithiasis and hyperlipidemia, we identified 167 DEGs and 74 hub genes through WGCNA. Using PPI networks and machine learning techniques, we recognized three frequently diagnostic genes (HSP90AB1, HSPA5, and STUB1), which demonstrated high diagnostic validity. The functional enrichment of these three diagnostic genes primarily involved pathways related to cellular metabolism.
ConclusionsOur study identified three candidate diagnostic genes that can predict nephrolithiasis in conjunction with hyperlipidemia, providing a solid foundation for further exploration into the pathogenesis of nephrolithiasis and hyperlipidemia.
To construct and validate a prediction model for enteral feeding intolerance in critically ill patients during the first 7 days of enteral feeding.
A retrospective cohort study.
We reviewed the medical records of two intensive care units from January 2015 to August 2023, to develop a prediction model by univariate analysis and logistic regression analysis. Model's performance was evaluated through discrimination, calibration and decision curve analysis.
This study involved a total of 471 patients, with an enteral feeding intolerance incidence rate of 35.7%. The prediction model comprised six variables, namely neurological disease, chronic gastrointestinal disease, Acute Physiological and Chronic Health Assessment II score, sedatives, acid suppressants and serum albumin. The model showed robust discrimination, calibration and clinical net benefit, indicating significant potential for practical application with readily available variables.
The model demonstrated strong predictive performance in assessing the risk of enteral feeding intolerance during the early stage of nutrition initiation.
Enhancing clinicians' capacity to reduce the incidence of enteral feeding intolerance and improve patient outcomes.
The prediction model shows a good capacity to discriminate critically ill patients at risk of enteral feeding intolerance, is helpful to provide personalised care.

BackgroundGastric cancer (GC) is a highly malignant gastrointestinal tumor characterized by difficult early diagnosis and poor prognosis. Therefore, it is imperative to explore potential therapeutic targets for gastric cancer. PARP9 is abnormally expressed in a variety of tumors and is associated with tumor cell apoptosis and DNA damage. However, its relationship with GC has not been fully studied.
MethodsThe expression and prognostic significance of PARP9 in gastric cancer (GC) were examined using bioinformatics approaches. Cell lines with either knockdown or overexpression of PARP9 were established through lentiviral transduction, and the role of PARP9 in the malignant phenotypes of GC cells was validated via CCK8 assays, wound healing assays, clonogenic assays, and Transwell migration experiments. Finally, alterations in downstream targets and signaling pathways following changes in PARP9 expression were analyzed through RNA sequencing.
ResultsPARP9 is highly expressed in GC tissues and is associated with poor prognosis. PARP9 knockdown can significantly inhibit the proliferation, invasion and migration of GC cells, and increase the apoptosis and DNA damage of GC cells. The therapeutic process of PARP9 in GC may be realized by synergistic interaction with SOX6 through MAPK signaling pathway.
ConclusionsOur study reveals a potential link between PARP9 and GC, providing a new target for the treatment of GC.

Obesity is associated with abnormal repolarization manifested by QT interval prolongation, and oxidative stress is an important link between obesity and arrhythmias. However, the underlying electrophysiological and molecular mechanisms remain unclear. The aim of this study is to evaluate the role of obesity in potassium current in ventricular myocytes and the potential mechanism of NADPH oxidase 2 (Nox2). We investigated the effect of Nox2 on cardiac repolarization without compromising its expression and function in other systems using mice with conditional cardiac-specific deletions of Nox2 (knockout [KO]). Wild-type, KO, and Flox littermate mice were randomized to either the control or high-fat diet (HFD) groups. Surface electrocardiograms were recorded to analyze repolarization in vivo. Whole-cell patch-clamp techniques were used to evaluate the electrophysiological phenotype of isolated myocytes in vitro. Western blotting was performed to assess protein expression levels. Compared with the control mice, the HFD group had a prolonged QTc. The consequences of an HFD were not attributed to delayed rectifier K+ and inward-rectifier K+ currents but were associated with reduced peak outward KV and fast transient outward K+ currents. Downregulated expression of KV4.2 and KChIP2, comprising functional Ito channel pore-forming (α) and accessory (β) subunits, was detected in HFD mice. Nox2-KO reversed the effect of obesity on Ipeak and Ito amplitude. Our data demonstrate that obesity mediates impaired cardiac repolarization in mice, manifested by QTc at the whole organism level and action potential duration at the cellular level, and correlated with Nox2. The electrophysiological and molecular aspects of this phenomenon were mediated by repolarizing outward K+ currents.To investigate the risk factors associated with frailty in older patients with ischaemic stroke, develop a nomogram and apply it clinically.
A cross-sectional study.
Altogether, 567 patients who experienced ischaemic strokes between March and December 2023 were temporally divided into training (n = 452) and validation (n = 115) sets and dichotomised into frail and non-frail groups using the Tilburg Frailty Indicator scale. In the training set, feature selection was performed using least absolute shrinkage and selection operator regression and random forest recursive feature elimination, followed by nomogram construction using binary logistic regression. Internal validation was performed through bootstrap re-sampling and the validation set was used to assess model generalisability. The receiver operating characteristic curve, Hosmer–Lemeshow test, Brier score, calibration curve, decision curve analysis and clinical impact curve were used to evaluate nomogram performance.
The prevalence of frailty was 58.6%. Marital status, smoking, history of falls (in the preceding year), physical exercise, polypharmacy, albumin levels, activities of daily living, dysphagia and cognitive impairment were predictors in the nomogram. Receiver operating characteristic curve analysis indicated outstanding discrimination of the nomogram. The Hosmer–Lemeshow test, calibration curve and Brier score results confirmed good model consistency and predictive accuracy. The clinical decision and impact curve demonstrated notable clinical utility. This free, dynamic nomogram, created for interactive use and promotion, is available at: https://dongdongshen.shinyapps.io/DynNomapp/.
This nomogram may serve as an effective tool for assessing frailty risk in older patients with ischaemic stroke.
The nomogram in this study may assist healthcare professionals in identifying high-risk patients with frailty and understanding related factors, thereby providing more personalised risk management.

In order to study the optimal use of Lactobacillus plantarum in sea cucumber (Apostichopus japonicus), 49 days feeding trial was conducted to determine the influence of immersion bathing in different concentrations of Lactobacillus plantarum CLY-05 on body weight gain rate and non-specific immune activities. The potential effect of CLY-05 on gut microbiota was also analyzed during the immersion bathing at the optimum concentration. The results showed that the body weight growth rate of all bathing groups was higher than that of control. The highest specific growth rate (4.58%) and weight gain rate (25.35%) was achieved at the bacterial concentration of 1×103 CFU/mL. The activities of non-specific immune enzymes (ACP, AKP, SOD and LZM) of all bathing groups increased after immersion bathing, and the enzyme activities of groups bathed with the bacterium at 1×103 and 1×104 CFU/mL reached the highest. Therefore, 1×103 CFU/mL was considered as the optimum concentration of L. plantarum CLY-05 for A. japonicus pond culture. The results of gut microbiota analysis showed that the gut microbiota changed with the addition of L. plantarum CLY-05, and the richness and diversity of the gut microbiota peaked on day 14 and day 21, respectively. The correlation analysis revealed that the non-specific immune enzyme activities were significantly correlated to some gut bacteria (in the phyla Proteobacteria, Firmicutes) after immersion bathing in L. plantarum CLY-05. These findings provide the theoretical foundation for probiotic application in sea cucumber farming.by Wenli Cao, Xiaofeng Pan, Liming Jin, Jie Liu, Jie Cao, Lei Jin, Fangqiang Wei
Complex liver cancer is often difficult to expose or dissect, and the surgery is often challenging. 3D-printed models may realistically present 3D anatomical structure, which has certain value in planning and training of liver surgery. However, the existing 3D-printed models are all monolithic models, which are difficult to reuse and limited in clinical application. It is also rare to carry fluorescence to accurately present tumor lesions. Here we report reusable fluorescent assembled 3D-printed models to mimic minimally invasive resection of complex liver cancer. Based on the models, multiple copies of liver lesion structure assembled accessories can be printed for the same patient or different patients, ensuring the quantity and quality of simulated surgical training, and greatly reducing the cost of simulated surgical training. The addition of fluorescence is helpful in accurately presenting tumor lesions. The reusable fluorescent assembled 3D-printed models may mimic minimally invasive resection of complex liver cancer, demonstrating potential value in simulated surgery.by Hao-nan He, Hong Xiao, Rui-jie Yao, Shi-jie Liao, Jun-hang Zheng, Hui-liang Zhou
Cryptorchidism is a common cause of male infertility, often necessitating microdissection testicular sperm extraction (m-TESE) for sperm retrieval post-surgery. However, uncertainties persist regarding m-TESE outcomes and influencing factors following cryptorchidism surgery. A systematic review and meta-analysis were conducted to evaluate sperm retrieval rates (SRR) among patients undergoing m-TESE after cryptorchidism surgery. Factors including age at orchidopexy, age at m-TESE, type of cryptorchidism, serum hormone levels, testicular volume, and interval from surgery to m-TESE were analyzed for their impact on SRR.Nine studies encompassing 935 patients were included. The overall SRR was 57% (95% confidence interval [CI] 51% to 63%). Compared to patients with negative sperm retrieval (SR-), patients with positive sperm retrieval (SR+) underwent m-TESE at an older age (1.81 years; 95% CI 1.17 to 2.45) and orchidopexy at a younger age (-3.35 years; 95% CI -6.34 to -0.36). Different types of cryptorchidism (including high scrotal, inguinal canal, intra-abdominal) significantly influenced SRR (P0.05). Furthermore, SR- patients typically experienced shorter intervals from orchidopexy to m-TESE compared to SR+ patients (34.09 months; 95% CI 0.40 to 67.77). Earlier orchidopexy and much later m-TESE procedures, as well as undescended testis closer to the scrotum, increase the likelihood of successful sperm retrieval. Orchidopexy for cryptorchidism should be done as early as possible, whether it is performed before 18 months of age or detected at a much older age. In patients with undetected cryptorchidism and azoospermia after puberty, m-TESE should not be performed immediately after orchidopexy, the optimal interval from orchidopexy to m-TESE still requires further study.Home parenteral nutrition (HPN) can improve the nutritional status of patients with gastrointestinal dysfunction. However, some patients face a series of challenges during its implementation, which significantly affect their quality of life.
To explore the experience and needs of living with home parenteral nutrition in adult patients.
A systematic review and meta-synthesis.
A search was conducted across multiple databases, including PubMed, Embase, Cochrane Library, Web of Science, Chinese Biomedical Literature Service System, China National Knowledge Infrastructure, Wanfang Database and Wipu Database, to explore the real-life experiences and needs of adult patients receiving HPN. The search covered the period up to March 2024. Qualitative research quality was evaluated using the Joanna Briggs Institute's Australian Centre for Evidence-Based Health Care Quality Assessment Criteria for Qualitative Research. Data synthesis was performed using Thomas and Harden's method of thematic and content analysis.
Twelve studies, each offering qualitative data, were analysed, resulting in the identification of four themes: positive experiences of HPN; the interplay of dynamic changes across physical, mental and social levels; self-adjustment to the new normal; and multidimensional needs of patients receiving HPN.
Patients receiving HPN face multiple challenges physically, psychologically and socially. This paper also reveals the supportive needs of patients in adapting to a new lifestyle with HPN. This indicates that healthcare professionals should provide comprehensive, continuous and dynamic supportive medical services to facilitate patients' reintegration and return to normal social life.
As this study constitutes a meta-synthesis, patient or public contribution is not applicable.
Adhering to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) reporting guidelines, this meta-synthesis was conducted.

PurposeGiven the unique features of the liver, it is necessary to combine immunotherapy with other therapies to improve its efficacy in patients of advanced cancer with liver metastases (LM). High-intensity focused ultrasound (HIFU) ablation is now widely used in clinical practice and can enhanced immune benefits. The study is intended to prospectively evaluate the safety and clinical feasibility of HIFU ablation in combination with systemic immunotherapy for patients with liver metastases.
MethodsThe study enrolled 14 patients with LM who received ultrasound-guided HIFU ablation combined with immune checkpoint inhibitors (ICIs) such as anti-programmed cell death protein 1 (anti-PD-1 agents manufactured in China) at Mianyang Central Hospital. Patients were followed up for adverse events (AEs) during the trial, using the CommonTerminology Criteria for Adverse Events v5.0(CTCAE v5.0) as the standard. Tumour response after treatment was assessed using computerized tomography.
ResultsThe 14 patients (age range, 35–84 years) underwent HIFU ablation at 19 metastatic sites and systemic immunotherapy. The mean lesion volume was 179.9 cm3 (maximum: 733.1 cm3). Median follow-up for this trial was 9 months (range: 3–21) months. The study is clinically feasible and acceptable to patients.
ConclusionThis prospective study confirmed that HIFU combined with immunotherapy is clinically feasible and safe for treating liver metastases.
To identify and appraise the quality of evidence of transitional care interventions on quality of life in lung cancer patients.
Quality of life is a strong predictor of survival. The transition from hospital to home is a high-risk period for patients' readmission and death, which seriously affect their quality of life.
Systematic review and meta-analysis.
The PubMed, Embase, Cochrane Library, Web of Science and CINAHL databases were searched from inception to 22 October 2022. The primary outcome was quality of life. Statistical analysis was conducted using Review Manager 5.4, results were expressed as standard mean difference (SMD) with a 95% confidence interval (CI). The risk of bias of the included studies was assessed using the Cochrane risk of bias assessment tool. This study was complied with PRISMA guidelines and previously registered in PROSPERO (CRD42023429464).
Fourteen randomized controlled trials were included consisting of a total of 1700 participants, and 12 studies were included in the meta-analysis. It was found that transitional care interventions significantly improved quality of life (SMD = 0.21, 95% CI: 0.02 to 0.40, p = .03) and helped reduce symptoms (SMD = −0.65, 95% CI: −1.13 to −0.18, p = .007) in lung cancer patients, but did not significantly reduce anxiety and depression, and the effect on self-efficacy was unclear.
This study shows that transitional care interventions can improve quality of life and reduce symptoms in patients, and that primarily educational interventions based on symptom management theory appeared to be more effective. But, there was no statistically significant effect on anxiety and depression.
This study provides references for the application of transitional care interventions in the field of lung cancer care, and encourages nurses and physicians to apply transitional care plans to facilitate patients' safe transition from hospital to home.

We conducted this study aimed to examine the impact of evidence-based nursing interventions on postoperative wound pain and complications after surgery for finger tendon injury. A total of 86 patients treated for finger tendon injuries at our hospital from January 2021 to October 2023 were selected and randomly divided into an experimental group and a control group. The control group received conventional nursing care, while the experimental group received evidence-based nursing interventions. The study compared the postoperative wound pain intensity, incidence of complications and patient satisfaction with nursing care between the two groups. The analysis revealed that compared with conventional care, evidence-based nursing interventions significantly reduced the level of wound pain (p = 0.034) and the incidence of complications (4.65% vs. 18.60%, p = 0.043). It also increased patient satisfaction with the nursing care (97.67% vs. 83.72%, p = 0.026). The study indicates that the application of evidence-based nursing interventions for patients with finger tendon injuries can reduce postoperative wound pain, decrease the incidence of complications and enhance patient satisfaction with nursing care.
The clinical significance of cancer-related stigma on patients' well-being has been widely established. Stigma can be perceived and internalised by cancer patients or implemented by the general population and healthcare workers. Various interventions have been carried out to reduce cancer-related stigma, but their effectiveness is not well-understood. This review aims to synthesise evidence on the effectiveness of interventions to reduce cancer-related stigma.
An integrative review.
This integrative review combined both qualitative and quantitative studies and followed five steps to identify problems, search for the literature, appraise the literature quality, analyse data, and present data. Mixed Methods Appraisal Tool (version 2018) was applied to evaluate the quality of the included studies.
Databases included Web of Science, MEDLINE, SpringerLink, Wiley Online Journals, Cochrane Library, ScienceDirect, OVID, and China National Knowledge Infrastructure (from the inception of each database to 30 April 2021).
Eighteen quantitative, six qualitative, and five mixed-methods studies were included in this review. Cultural factors should be considered when conducting interventions to reduce cancer-related stigma. For cancer patients, multi-component interventions have demonstrated a positive effect on their perceived stigma. For general population, interactive interventions show promise to reduce their implemented stigma towards cancer patients. For healthcare workers, there is a paucity of studies to reduce their implemented stigma. Existing studies reported inconclusive evidence, partially due to the lack of a robust study design with an adequate sample size.
Multi-component and interactive interventions show promise to relieve cancer-related stigma. More methodologically robust studies should be conducted in different cultures to elucidate the most appropriate interventions for different populations to reduce cancer-related stigma.
These findings will facilitate healthcare workers to design and implement interventions to reduce cancer-related stigma, thus improving the quality of life for cancer patients.

The purpose of this study was to compare the reconstructive outcomes of soft-tissue defects around foot and ankle with vaccum sealing drainage (VSD) or induction membrane (IM) of cement formation and attempt to provide an optimal strategy for elderly patients. A retrospective review of all continuous patients with foot and ankle reconstruction using different flaps from October of 2016 and October of 2020 was performed. Based on the different way, the patients were divided into two groups: VSD group (n = 26) and IM group (n = 27). Outcomes were assessed according to the size of the defect, frequency of debridement procedures, hospitalization time, duration of healing, the healing rate, major amputation rate, functional outcomes and complications. Immunohistochemistry (IHC) detection of vascular endothelial growth factor (VEGF) was also be completed. We found that there was no difference in demographic characteristics, size of the defect, debridement times and functional outcomes between the two groups (p > 0.05); however, a significant difference in the wound healing time, hospitalization time and complications were noted between them(p < 0.05). The fresh granulation tissue of both groups showed abundant positive expression of VEGF. Thus, the VSD and IM are both available for foot and ankle reconstruction in elderly patients. However, the IM group offers short hospitalization time, duration of healing and lower frequency of postoperative complications. Thus, we advocate the IM for reconstruction of defects of the foot and ankle region in the elderly patients.
A meta-analysis study was executed to measure the effect of minimally invasive surgery (MIS) and open surgical management (OSM) on wound infection (WI) in female's cervical cancer (CC). A comprehensive literature study till February 2023 was applied and 1675 interrelated investigations were reviewed. The 41 chosen investigations enclosed 10 204 females with CC and were in the chosen investigations' starting point, 4294 of them were utilizing MIS, and 5910 were utilizing OSM. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were utilized to compute the value of the effect of MIS and OSM on WI in female's CC and by the dichotomous approaches and a fixed or random model. The MIS had significantly lower WI (OR, 0.23; 95% CI, 0.15–0.35, p < 0.001) with no heterogeneity (I 2 = 0%) and postoperative aggregate complications (PACs) (OR, 0.49; 95% CI, 0.37–0.64, p < 0.001) in females with CC and compared OSM. However, MIS compared with OSM in females with CC and had no significant difference in pelvic infection and abscess (PIA) (OR, 0.59; 95% CI, 0.31–1.16, p = 0.13). The MIS had significantly lower WI, and PACs, though, had no significant difference in PIA in females with CC and compared with OSM. However, care must be exercised when dealing with its values because of the low sample size of some of the nominated investigations for the meta-analysis.
