The angiotensin converting enzyme 2/angiotensin-(1–7)/Mas receptor axis plays an important role in the regulation of blood pressure. G protein-coupled receptor kinase 4 (GRK4) has attracted more attentions by modulating G protein-coupled receptors and blood pressure. However, it remains unknown whether renal Mas receptor is regulated by GRK4 and its role in the pathogenesis of hypertension. Compared with Wistar-Kyoto (WKY) rats, spontaneously hypertensive rats (SHRs) exhibited impaired Mas receptor-mediated diuresis and natriuresis, which was accompanied with increased phosphorylation levels of Mas receptors. Similarly, the phosphorylation of renal Mas receptor was increased and its-induced renal effects were decreased in human (h) GRK4γ 142V transgenic mice relative to wild-type littermates. There was a colocalization and a direct interaction of renal Mas receptor and GRK4, which were increased in SHRs and confirmed by rigid protein–protein docking. In vitro studies found that treatment with the Mas receptor agonist AVE0991 inhibited Na+-K+-ATPase activity in WKY renal proximal tubule (RPT) cells, which was failed in SHR cells. GRK4 silencing decreased the phosphorylation of Mas receptor and improved the impaired Mas receptor-mediated inhibition of Na+-K+-ATPase activity in SHR RPT cells. Further study showed that ultrasound-targeted microbubble destruction-targeted renal GRK4 depletion decreased Mas receptor phosphorylation and improved its-induced diuresis and natriuresis in SHRs. These suggest that GRK4 contributes to increased renal Mas receptor phosphorylation and dysfunction in hypertension, indicating that targeting GRK4 may be a viable therapeutic approach for hypertension.Medication errors, particularly during administration, are a major threat to patient safety, with interruptions being a key contributor. Nurses are the most affected by these disruptions, and various interventions have been proposed to reduce interruptions.
This review evaluates the effectiveness of preventive and responsive interventions aimed at reducing interruptions during medication administration.
A systematic search of multiple databases identified 14 eligible studies on interventions targeting nurse interruptions. The review includes randomized controlled trials and quasi-experimental studies, focusing on interruption and medication error rates. Significant heterogeneity prevented meta-analysis.
Preventive strategies, like no-interruption vests and awareness campaigns, may reduce interruptions from external sources, but nurse-to-nurse interruptions remained common. Responsive strategies showed limited success in reducing interruptions but improved nurses' ability to manage them. The impact on medication errors was inconclusive.
Preventive strategies help reduce interruptions, but more targeted interventions are needed for nurse-to-nurse disruptions. A combined approach of preventive and responsive strategies can enhance medication safety.
This study aimed to systematically review Clinical Practice Guidelines (CPGs) for nutritional management of dementia and use evidence mapping to highlight research trends and identify gaps to inform future research.
A systematic review of guidelines using the PRISMA statement.
Systematically collect literature on dementia management CPGs from PubMed, Embase, Web of Science and guideline databases. Extract basic information, recommendations, methodological quality and reporting quality of the CPGs. Four researchers independently evaluated eligible CPGs using the AGREE II instrument and the RIGHT checklist. All recommendations from the CPGs were summarised and analysed, and evidence mapping bubble charts were created in Excel.
After excluding 5541 records, 10 CPGs were eventually proved eligible, 5 of which were of high quality and 5 of high quality. With 10 CPGs that combined 18 recommendations. The nutrition screening and assessment were summarised on the basis of the dementia recommendations for 4 major items, 7 items on nutritional interventions, 5 items on caring and 2 on education.
This review provides an evidence map and offers new perspectives on CPGs for nutritional management in dementia. However, there are improvements to the included CPGs, but most CPGs have a number of key recommendations that can help guide clinical practice.
The currently available guidelines on dementia nutritional management have room for methodological improvement.
To identify the principal factors influencing the implementation of high-value healthcare performance evaluation and to examine the interrelationships among these factors.
Value-based health care (VBHC) is gaining momentum as a model that focuses on improving patient outcomes. However, there is still a lack of understanding of the multifaceted factors that contribute to its successful implementation.
Theoretical modelling and mixed research methods.
First, this study constructed a framework of influencing factors on the implementation of VBHC performance evaluation based on the Technology-Organization-Environment model. Second, a representative set of influencing factors for healthcare performance evaluation was identified. The implementation of performance evaluation was identified based on a literature analysis and a case study in China. Finally, experts were invited to assess the relevance of the aforementioned influencing factors, and the collected data were analysed using Interpretative Structural Model. The PRISMA-ScR checklist guided the reporting of this study.
We initially constructed the theory framework with the objective of categorising and summarising the influential factors and potential problems revealed in the implementation of patient VBHC performance evaluation in general hospitals. Subsequently, 15 key factors were identified through interviews with 10 experts. Then, a six-level hierarchy was developed to construct a visual structure diagram, the purpose of which was to clarify the hierarchy of roles of each influencing factor. Finally, we categorise the influencing factors into four clusters based on their driving power and dependency within the system.
The insights from this research will assist hospital managers in identifying and prioritising the key factors that influence high-value healthcare performance.
This study provides a reliable pathway reference for clinical and nursing performance value enhancement and provides important insights into resource allocation and decision-making for clinical practitioners.

Pregnancy is a special time for women that involves substantial emotional, physical, social, and family changes, which can lead to physical and psychological harm. The rapid development of e-health has provided a favourable platform for managing health-related outcomes in pregnant women, and nurses are the professional group that is most likely to provide e-health services. Nurse-led e-health interventions have attracted increasing attention, but their effects are uncertain.
To identify the effectiveness of nurse-led e-health interventions in improving health-related outcomes in pregnant women.
A systematic review.
The PubMed, PsycINFO, EMBASE, CINAHL, ProQuest, MEDLINE, Scopus, Web of Science and Cochrane Library databases were searched from inception to March 2023.
Two reviewers independently assessed study eligibility and extracted data. The Cochrane risk of bias tool was used for quality assessment. The findings of this review are presented using a narrative synthesis.
This review included 14 studies involving 2016 participants. Three out of five studies reported that nurse-led e-health interventions significantly reduced depressive symptoms. Four studies reported significant improvements in stress and self-efficacy after the intervention. Two studies reported significant improvements in anxiety symptoms, self-management ability, and quality of life after the intervention. One study showed that weight gain and physical activity significantly improved after the intervention. Due to the heterogeneity in the included studies, no meta-analysis was conducted.
Nurse-led e-health interventions may be beneficial for improving anxiety symptoms, depressive symptoms, stress, self-efficacy, weight gain, self-management ability, physical activity, and quality of life in pregnant women.
Nurse-led e-health interventions could provide individualised, economic, interactive, and convenient nursing modes for pregnant women. Rigorous and high-quality evidence confirming the long-term effects of these interventions on pregnant women is necessary.
The patients had no direct involvement in the present study.

Cancer is a global public health concern that causes psychosocial and spiritual challenges in those who suffer from it and their family caregivers. Meaning-centered interventions have a positive impact on improving anxiety and depression in patients with advanced cancer. However, the impact of meaning-centered interventions on existential distress of patients with cancer and family caregivers' mental health is still unclear.
To examine the efficacy of meaning-centered interventions in alleviating existential distress, enhancing quality of life, and fostering a sense of meaning among cancer survivors and their family caregivers.
This systematic review and meta-analysis were conducted according to the Preferred Reporting Item for Systematic Reviews and Meta-analysis 2020 statement. A comprehensive search was conducted from inception until September 2023 across nine databases: PubMed, Embase, Web of Science, PsycINFO, The Cochrane Library, CINAHL, Scopus, WANFANG, and CNKI. Heterogeneity testing and meta-analyses were conducted using Review Manger 5.3. We calculated standard mean deviations and 95% confidence intervals and presented forest plots for assessing intervention effects. Two reviewers independently evaluated the risk of bias of all included articles. STATA 17.0 was used for publication bias analysis.
The review included 25 studies with 2399 participants, and 22 were included in the meta-analysis. Meaning-centered interventions enhanced quality of life, alleviated existential distress, and reduced depressive symptoms and cancer-related fatigue. They did not affect spiritual well-being. The subgroup analysis showed that the individual form and long-term intervention (≥3 months) enhanced the quality of life in cancer survivors. Meaning-centered interventions reduce depression in advanced cancer survivors more than in mixed-stage cancer survivors. Meaning-centered interventions significantly enhanced benefit finding for family caregivers.
Meaning-centered interventions may improve mental health for patients with cancer and their family caregivers. Future research must include diverse cultural perspectives to understand the impact of meaning-centered interventions on various groups.
Conduct a systematic review of existing studies on intrinsic capacity (IC) and a meta-analysis of studies to assess the overall effectiveness of ICOPE in improving IC in older adults.
Ten databases were systematically searched from inception to November 8, 2023, and the search was last updated on January 2, 2024. Randomised controlled trials (RCTs) were included. The main outcomes were IC (cognition, psychological, sensory, vitality and locomotion).
The results showed ICOPE had a significant effect in improving cognitive function (SMD = 0.36; 95% CI, 0.17 to 0.56, p < 0.001, 12 RCTs, 7926 participants) and depressive symptoms (SMD = −0.70; 95% CI, −0.96 to −0.43, p < 0.001, 26 RCTs, 11,034 participants), but there was no statistically significant difference in improving locomotion (SMD = 0.16; 95% CI, −0.03 to 0.34, p = 0.098, 3 RCTs, 1580 participants). Meta-regression analysis shows that intervention duration should be paid attention to when the source of heterogeneity is discussed on the cognition.
The results suggest that ICOPE may be a potentially effective approach to help improve the IC in older adults, showing significant potential for improving cognitive function and reducing depressive symptoms in particular.
ICOPE is expected to provide effective strategies to enhance issues such as IC and may be an innovative way to improve the overall health of older adults. This result provides strong support for geriatric nursing practice and encourages the adoption of ICOPE as a viable nursing approach to promote healthy ageing.

This paper focuses on the cooperative driving challenges of connected and automated vehicles (CAVs) at single-lane roundabouts. First, a geometric path planning method is proposed for CAVs navigating a single-lane roundabout. Based on this method, a vehicle roundabout model is established. Four potential traffic scenarios for CAVs are established, and the optimal arrival times at conflict points are analyzed. By correlating the optimal arrival times at conflict points with the optimal entry times into the roundabout, the multi-vehicle coordination problem in complex intersections is simplified to a speed control issue during entry. Utilizing the principles of optimal control and Pontryagin minimization, two speed optimization strategies are proposed. Finally, MATLAB is employed for simulation analysis. The results indicate that the control strategy proposed in this paper enables the system to clearly identify potential conflicts between vehicles and implement an optimal control strategy, ensuring that vehicles can navigate the roundabout efficiently in terms of time and fuel without collisions. Additionally, the minimum time interval is established at 0.2 seconds to completely prevent vehicle collisions. In this study, the fusion problem involving two vehicles at a single conflict point is further expanded to encompass multiple vehicles at multiple conflict points. Thus, the efficient scheduling of multiple vehicles in single-lane roundabouts is realized.To establish and validate a set of best nursing practice indicators for medical groups in Chinese general hospitals based on value-based healthcare (VBHC) theory.
A modified Delphi method.
This study engaged experienced clinical nurses from public hospitals and multidisciplinary experts in operations management. Through a literature review and structured brainstorming, a comprehensive framework for assessing best nursing practices in Chinese general hospital medical groups was developed. A modified Delphi method was then employed to establish an indicator framework, followed by the Combined Empowerment-MABAC method to weight and validate the indicators using empirical data collected between June 2023 and October 2023. The CREDES checklist guided the reporting of this study.
Sixteen experts, each with at least 10 years of experience in nurse management from nine healthcare organizations, participated in two rounds of consultation. The experts' responses and suggestions for rewording, deleting and adding items were incorporated into each round. Of the 34 proposed indicators, 25 were approved, covering healthcare service capacity, efficiency, quality and safety, patient experience and cost.
The Delphi survey reached a consensus on necessary actions to improve nursing performance. The developed indicator system provides a foundational framework for standardizing the monitoring of care quality and performance assessment in Chinese clinical healthcare groups, with broad applicability.
This study provides a reliable basis for developing a nursing performance assessment database, offering crucial insights for measuring quality of care and improving patient value.

To examine the effectiveness of family-centred interventions among family caregivers.
Family-centred interventions are an emerging form of intervention that can be effective at improving physical and mental health outcomes for patients and family caregivers. To date, no reviews have examined the effectiveness of family-centred interventions for family caregivers.
A systematic review, including a meta-analysis, was conducted according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA 2020) checklist.
Seven English and two Chinese electronic databases were compressively searched from the outset to March 2023. Two researchers independently reviewed the abstracts and full texts, extracted the data and assessed the risk of bias independently by using the Cochrane ‘Risk of bias assessment tool’.
This systematic review and meta-analysis included 20 articles. The results of the meta-analysis showed that family-centred interventions could significantly improve caregiver burden (p=0.003), quality of life (p = 0.007), depression (p = 0.0002), and stress (p < 0.0001) but not anxiety or family functioning. According to our subgroup analysis, the family-centred empowerment model (p = 0.009) was superior to the other family intervention (p=0.004) in reducing caregiver burden. Family-centred interventions are more effective at reducing the burden of caregiving on family caregivers of adolescent patients (SMD=−0.79, 95% CI[−1.22,−0.36], p = 0.0003) than on adult patients (SMD=−0.37, 95% CI [−0.61,−0.12], p = 0.004).
Family-centred interventions could enhance family caregivers’ burden, quality of life, stress and depression but had no significant impact on anxiety or family functioning.
Family-centred interventions have the potential to improve the health status and caregiving burden of family caregivers. Rigorous and high-quality evidence is needed to confirm the long-term effects of these interventions on family caregivers.

Keloids, pathological scars resulting from skin trauma, have traditionally posed significant clinical management challenges due to their persistence and high recurrence rates. Our research elucidates the pivotal roles of lipids and their derivatives in keloid development, driven by underlying mechanisms of abnormal cell proliferation, apoptosis, and extracellular matrix deposition. Key findings suggest that abnormalities in arachidonic acid (AA) synthesis and non-essential fatty acid synthesis are integral to keloid formation. Further, a complex interplay exists between lipid derivatives, notably butyric acid (BA), prostaglandin E2 (PGE2), prostaglandin D2 (PGD2), and the regulation of hyperfibrosis. Additionally, combinations of docosahexaenoic acid (DHA) with BA and 15-deoxy-Δ12,14-Prostaglandin J2 have exhibited pronounced cytotoxic effects. Among sphingolipids, ceramide (Cer) displayed limited pro-apoptotic effects in keloid fibroblasts (KFBs), whereas sphingosine 1-phosphate (S1P) was found to promote keloid hyperfibrosis, with its analogue, FTY720, demonstrating contrasting benefits. Both Vitamin D and hexadecylphosphorylcholine (HePC) showed potential antifibrotic and antiproliferative properties, suggesting their utility in keloid management. While keloids remain a prevalent concern in clinical practice, this study underscores the promising potential of targeting specific lipid molecules for the advancement of keloid therapeutic strategies.
Various factors contribute to different types of surgical site infections (SSI) in gastric cancer patients undergoing surgery, and the risk factors remain uncertain. This meta-analysis aims to clarify the relationship between various factors and SSI, resolving existing controversies. Thirty-four eligible articles with 66 066 patients were included in the meta-analysis. Significant risk factors for SSI included age ≥65 years, male gender, BMI ≥25 kg/m2, diabetes, hypertension, advanced TNM stage ≥III, pathologic T stage ≥T3, pathologic N stage ≥N1, ASA ≥3, open surgery, blood transfusion, extensive resection, combined resection, splenectomy, D2 or more lymph node dissection, and operative time ≥240 min. Operative time showed a nonlinear relationship with SSI risk. Subgroup analysis revealed significant differences in the effects of risk factors among different infection types. These findings inform the development of targeted preventive measures to reduce SSI rates.
A meta-analysis was implemented to appraise the effect of hydrocolloid dressings (HCDs) in the management of different grades of pressure wound ulcers (PWUs) in critically ill adult subjects (CIUSs). Inclusive literature research until April 2023 was done, and 969 interconnected researches were revised. The 8 picked researches, enclosed 679 critically ill adult persons at the utilized researchers' starting point; 355 of them were utilizing HCDs, and 324 were controls. Odds ratio (OR) and 95% confidence intervals (CIs) were utilized to appraise the consequences of HCDs in treating CIUSs by the dichotomous approach and a fixed or random model. HCDs had significantly higher PWU complete healing (OR, 2.15; 95% CI, 1.54–3.02, p < 0.001), PWU stage II ulcers complete healing (OR, 2.82; 95% CI, 1.40–5.69, p = 0.004), and PWU stage III ulcers complete healing (OR, 3.73; 95% CI, 1.23–11.35, p = 0.02) compared to control in critically ill adult persons. HCDs had significantly higher PWU complete healing, PWU stage II ulcers complete healing, and PWU stage III ulcers complete healing compared with control in critically ill adult persons. However, caution needs to be taken when interacting with its values since there was a low sample size of most of the chosen research found for the comparisons in the meta-analysis.
Increased intraocular pressure (IOP) is a risk factor for glaucoma. One treatment option is trabeculectomy. Antimetabolic agents are used in the operation to decrease the post-operative scarring of the wound. The two most common medicines are Mitomycin C (MMC) and 5-Fluorouracil (5-FU). The aim of this research is to assess the effect of MMC on post-operation wound healing in comparison with 5-FU in addition to trabeculectomy. Well, we went through four common databases. Our language was limited to English during the study. The last time we looked at the e-databases was August 2023. Case control studies were performed where MMC resulted in better wound healing than 5-FU. Researchers selected a total of 1023 trials and eventually selected six trials for data analysis. Four hundred and ninety one cases of glaucoma were treated with trabeculectomy. Among them, 246 were given MMC and 245 were given 5-FU during operation. Six trials showed that there was no statistical difference between MMC and 5-FU in the incidence of post-operative wound leak in glaucoma patients who received trabeculectomy (OR, 1.21; 95% CI, 0.63–2.30 p = 0.57); Five trials demonstrated that MMC was associated with a reduced risk of post-operative corneal damage compared to 5-FU injection (OR, 0.18; 95% CI, 0.06–0.56 p = 0.003); In both trials, the incidence of post-operative bleeding was not significantly different from that of 5-FU injected in the MMC group (OR, 0.33; 95% CI, 0.05–2.16 p = 0.25). Our results indicate that MMC is superior to 5-FU in the reduction of post-operative corneal injury. Additional comparisons between MMC and 5-FU are required in order to increase the reliability and effectiveness of these findings.
