Primary cilia play a crucial role in the development and mechanosensation of various tissue types, including bone. In this study, we investigated their role in bone growth and adaptation by targeting two cilia specific genes, IFT88 and MKS5. Conditional knockout (cKO) of IFT88 in osteoblasts significantly reduced body weight and femur length in mice compared to the littermate controls. Additionally, female IFT88 cKO mice exhibited a significant suppression of bone formation rate compared to the littermate controls. To further explore the role of primary cilia in osteocytes, osteocytes specific MKS5 cKO mice underwent axial ulnar loading at a peak force of 2.9N for females and 3.2N for males with 120 cycles per day for three consecutive days. Load induced bone formation rate was significantly decreased by 48% in males and 42% in females compared to the littermate control mice. These findings underscore the critical role of primary cilia in bone development and mechano-adaptation. They suggest that functional primary cilia in osteoblasts are essential for skeletal development, while those in osteocytes mediates mechanically induced bone formation, highlighting its potential as therapeutic targets for bone loss prevention.This prospective community-based cohort study (Acute Respiratory Infection Epidemiological Characteristics Assessment Study (ARI-ECAS)) aims to systematically monitor acute respiratory infection (ARI) incidence, characterise multiple pathogen coinfection patterns and explore microbial landscape dynamics in Shanghai’s general population. By integrating syndromic surveillance, molecular diagnostics and metagenomic sequencing, the study seeks to enhance understanding of ARI epidemiology, seasonal variation and host–pathogen interactions to inform predictive modelling and optimise public health interventions in high-density urban environments.
The study enrolled 15 199 permanent residents from all 16 districts of Shanghai, with baseline oropharyngeal swab samples across five representative districts (Xuhui, Jing’an, Jiading, Songjiang and Fengxian). Inclusion criteria required residency ≥6 months and consent for weekly follow-ups. Exclusion criteria addressed mobility limitations (planned relocation >6 months) and recent ARI history. Participants provided demographic, behavioural and clinical data via the Shanghai Health Cloud platform, with baseline and symptomatic-phase biological samples collected for analysis.
During the initial 8-month surveillance period (May 2024–January 2025), the ARI-ECAS cohort demonstrated critical insights into the epidemiology of acute respiratory infections in Shanghai’s urban communities. Among 15 199 participants, 10.96% reported symptomatic episodes, of whom 21.43% experienced recurrent infections. Pathogen detection using targeted next-generation sequencing (tNGS) identified microbial aetiologies in 53.52% of symptomatic cases, revealing a high prevalence of coinfections: 27.96% involved dual pathogens, while 33.01% showed polymicrobial interactions (≥3 pathogens). Notably, 85.09% of symptomatic episodes were self-managed, underscoring a low healthcare-seeking rate (14.91%) consistent with patterns observed in urban China during postpandemic transitions.
The current phase of data collection will conclude in June 2025; however, syndromic surveillance and tNGS protocols will be sustained to capture multiyear seasonal transmission patterns. To enhance comparative rigour, future protocols will aim to collect samples from participants during asymptomatic periods in the subsequent year to serve as seasonal baseline controls. Building on this foundation, the study will integrate contact behaviour and mobility surveys to quantify parameters critical for understanding pathogen transmission dynamics (eg, household contacts and public transportation usage). Furthermore, pathogen detection and metagenomic data will be combined with transcriptomic and metabolomic profiling in selected cases to model multipathogen interaction networks and delineate host immune response pathways, thereby advancing mechanistic insights into polymicrobial cocirculation.
Preoperative anxiety is prevalent among neurosurgical patients and is associated with adverse clinical outcomes. Virtual reality (VR) technology offers an innovative approach to delivering immersive preoperative education, particularly in familiarising patients with the intensive care unit (ICU) environment. This study aims to evaluate whether a VR-based ICU orientation can reduce perioperative anxiety and improve psychological preparedness in adult neurosurgical patients.
This single-centre randomised controlled trial plans to enrol 108 patients at Xuanwu Hospital. Using a computer-generated random sequence, participants will be randomly assigned in a 1:1 ratio to two groups: a control group receiving standard preoperative guidance, and an experimental group receiving standard guidance plus a VR-based ICU experience tour conducted 1 day before surgery. The primary outcome measure is the incidence of anxiety within 24 hours before discharge from the ICU. Secondary outcome measures include the incidence of depression, cognitive impairment and delirium, duration of delirium, safety events and other clinical outcomes. Data collection points include baseline (T0), 24 hours before surgery (T1), during ICU stay (T2) and 30 days after discharge (T3). All data analyses will be performed using SPSS V.26.0 software and will follow the intention-to-treat principle. This study seeks to determine the effectiveness of a VR-based ICU experience tour in reducing perioperative psychological stress and improving postoperative clinical outcomes.
This study was approved by the Ethics Committee of Xuanwu Hospital, Capital Medical University (Approval ID: (2024) NO.152-002). The initial approval was obtained on 4 July 2024, and remains valid through 4 July 2026. All participants will provide written informed consent before any data collection takes place. The research findings are intended to be disseminated through publication in peer-reviewed scientific journals.

To consolidate and synthesise the literature reporting perceptions of nurses and nursing students regarding evidence-based nursing.
Qualitative systematic review.
Seven electronic databases (Cumulative Index to Nursing and Allied Health Literature, Embase, ProQuest Dissertations & Theses Global, PsycInfo, PubMed, Scopus and Web of Science) were searched from their respective inception dates to January 2025.
The Preferred Reporting Items for Systematic reviews and Meta-Analysis guidelines guided this review. The quality of included studies was assessed using the Critical Appraisal Skills Programme tool, and data were synthesised thematically using Sandelowski and Barroso's two-step approach.
Thematic analysis of the 19 included studies, published from 2007 to 2025, identified three key themes: (1) Advancing nursing through evidence, (2) Personal, structural and systemic challenges and (3) Promoting a new evidence-based nursing culture.
Evidence-based nursing can elevate nursing care standards and enhance patient outcomes. Numerous factors that encourage and hinder the implementation of evidence-based nursing among nurses and nursing students were reported.
This review suggests the need to incentivise nurses to champion evidence-based nursing initiatives, provide nurses and nursing students with continuing education, and develop updated evidence-based nursing guidelines. These strategies could help in cultivating a supportive evidence-based nursing workplace culture and improving the implementation of evidence-based nursing.
Valuable insights into the facilitators and barriers associated with the implementation of evidence-based nursing were reported by nurses and nursing students—the key personnel responsible for practising evidence-based nursing. Future research could be undertaken to explore the perceptions of nurses and nursing students across varied cultural settings and in underrepresented regions.

To evaluate the feasibility, effectiveness, and acceptability of a spherical video-based virtual reality training programme aimed at helping nurses manage workplace violence.
A convergent mixed-methods study.
This study included nurses from a tertiary medical centre in Taiwan. The training programme involved four interactive 360° scenarios focused on recognising, de-escalating, and responding to workplace violence. Quantitative measures included risk perception, confidence in coping with aggression, and technology acceptance. Qualitative measures included the participants' learning experiences. Quantitative and qualitative findings were integrated through joint displays.
The programme was feasible, with all participants completing the training. Nurses reported high levels of perceived usefulness and ease of use. Quantitative data revealed considerable improvements in risk awareness and confidence in responding to incidents of violence. Qualitative data revealed that immersion and emotional resonance enhanced engagement, fostered self-reflection, and reinforced learning. Technical challenges included subtitle placement and speech recognition accuracy.
Spherical video-based virtual reality is a feasible, acceptable, and effective training approach that improves nurses' preparedness for managing workplace violence by enhancing situational awareness and confidence in addressing high-risk situations.
Integrating spherical video-based virtual reality into continual education may strengthen nurses' workplace safety competencies, prevent harm from incidents of violence, and improve patient care in stressful environments.
Workplace violence undermines nurse safety and patient care. Current training modules often lack contextual realism. Our programme improved nurses' awareness, confidence, and reflective learning and was feasible and well accepted. The findings are relevant to nursing educators, hospital administrators, and policymakers seeking sustainable strategies for addressing workplace violence.

Hypertension represents a major public health challenge globally, with a rising prevalence in China. This study aims to explore the factors shaping blood pressure (BP) control among hypertensive patients managed in community health centres (CHCs), with a particular emphasis on the association with age.
This was a population-based, observational study that used healthcare records from CHC in Shenzhen, covering the period from 1 January 2000 to 8 October 2024. Univariate and multivariate logistic regression analyses were employed to assess the independent associations of various factors with BP control rate. Additionally, the study evaluated the relationship between age and BP control across six distinct age subgroups.
The study included 1 073 914 participants who met the eligibility criteria, with 955 415 (88.97%) patients achieving BP control. The median baseline age was 55.9 (IQR 18–109) years. Individuals aged 45 years and above demonstrated better BP control rates (46–55, OR 1.053, 95% CI 1.020 to 1.087; 56–65, OR 1.246, 95% CI 1.205 to 1.289; 66–75, OR 2.183, 95% CI 2.103 to 2.265; >75, OR 2.159, 95% CI 2.060 to 2.262). Among young adults aged 18–35 years, increasing age was consistently associated with poorer BP control across most subgroups. For the middle-aged groups (36–45 and 46–65 years), age had little impact on BP control. In the 66–75 years age range, older age was linked to better BP control in some groups.
The association between age and BP control varied across age groups. Hypertension management strategies should be tailored to address the unique needs of different age groups, geographical regions and targeted populations.
As a framework to conceptualise well-being, the capability approach (CA) combines structural drivers with personal freedoms, making it a compelling approach for understanding women’s health and well-being (WHW). The WHW Project of the Exemplars in Global Health initiative chose the CA for its conceptual framing, while emphasising the influential role of gender and other intersecting inequalities (intersectional gender inequality) in shaping health and well-being over the life course. We discuss the Exemplars in Global Health – Women’s Health and Well-being (EGH-WHW) Framework and a scoping review that supports it.
To identify well-established and/or validated CA-based frameworks and measures attuned to intersectional gender inequality that analyse women’s well-being over the life course and across multiple geographies. If needed, to develop a new conceptual framework to analyse WHW over the life course through an intersectional gender inequality lens.
The scoping review, which was carried out between January and May 2024 and re-run in May 2025, adhered to the methodology by Arksey and O’Malley, Levac et al and Daudt et al, and the PRISMA-ScR (Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews) checklist. The EGH-WHW Framework was developed by a multidisciplinary Working Group comprising representatives of organisations in the WHW Project consortium.
The review drew upon database searches (Scopus, PubMed) and targeted online hand searches for CA-based frameworks and measures.
All CA-based frameworks and measures of multidimensional well-being were included. CA-based empirical research was considered if it applied a framework or measure; or if it analysed multidimensional well-being across multiple geographies.
Information about each type of CA-based application—its choice of well-being dimensions, methods, focus on inequality, intersectionality and the life course—was recorded in a data charting form. Thematic summative syntheses of publications about each CA-based framework or measure led up to an overall evaluative synthesis of the fit between existing work and our requirements.
The review culminated in 94 publications, including six frameworks and 14 measures that met only some of the WHW Project’s requirements: multidimensionality of well-being; attention to intersectional gender inequality and the life course; as well as demonstrated and intended measurements across multiple geographies.
The review reaffirms the need for the EGH-WHW Framework, which recognises that WHW depend on their freedom ‘to be’ and ‘to do’, and proposes three interconnected clusters of dimensions depicting key capabilities, agency and functionings that are sensitive to intersectional gender inequality and the life course. Each dimension is mapped to specific indicators to support comparative assessments of country performance and drivers of progress across low-income and middle-income countries.
The EGH-WHW Framework distinguishes itself from other CA-based frameworks by incorporating both an intersectional gender lens and a life course perspective. The framework’s conceptualisation of multidimensional well-being allows for a rich and nuanced foundation on which to build policies and programmes that address the complex determinants of health, well-being and human rights of different groups of girls and women.
Atrial fibrillation (AF), with a prevalence of 1–2%, is the most common cardiac arrhythmia. AF is associated with a fivefold increased risk of cardioembolic events; approximately 20% of all strokes are caused by AF. Pulmonary vein isolation (PVI) has become the first-line treatment for AF. However, PVI cannot eliminate the residual stroke risk. Current guidelines recommend that anticoagulation be continued in this specific group of patients, regardless of the presence or absence of AF. In this large AF population post-PVI, who are considered to be in an earlier stage of AF, it is unknown whether left atrial appendage closure (LAAC) offers an alternative to direct oral anticoagulant (DOAC) therapy.
The trial will be a prospective, randomised, multicentre non-inferiority study comparing two treatment strategies in AF patients after atrial ablation. Patients will be randomly assigned to either percutaneous LAAC (group A) or DOAC treatment (group B) in a 1:1 ratio; both sequential and concomitant planned ablation with or without LAAC are accepted. Randomisation will be conducted using web-based randomisation software. A total of 1012 participants (506 patients per group) will be enrolled. The primary effectiveness measure will be the occurrence of any of the specified events within 24 months after randomisation: stroke/transient ischaemic attack/systemic thromboembolism, cerebral haemorrhage, other major haemorrhages (Bleeding Academic Research Consortium ≥2), cardiovascular mortality and all-cause mortality.
The study was approved by the Ethical Review Board of Shanghai Chest Hospital, China (KS(Y)20287). Written informed consent will be obtained from all participants. The trial will follow the Declaration of Helsinki and Good Clinical Practice. Confidentiality will be maintained with anonymised, securely stored data. Findings will be disseminated through peer-reviewed publications and conferences.

Dementia contributes to the disease burden worldwide, and people with hypertension or type 2 diabetes are at an elevated risk of developing dementia. It is essential to prevent or delay cognitive decline in people at high risk within the community. Our trials aim to evaluate the effects of adaptive cognitive training on community-dwelling older adults with hypertension or type 2 diabetes but no dementia.
Two multicentre, double-blind, randomised, placebo-controlled trials, named COgNitive Training in community-dwelling older adults at high risk for demENTia and with Hypertension (CONTENT-Hypertension) and COgNitive Training in community-dwelling older adults at high risk for demENTia and with Diabetes (CONTENT-Diabetes), will be conducted to investigate the effects of adaptive cognitive training on participants aged 60 years or above who have been diagnosed with hypertension or type 2 diabetes but no dementia. Each trial will enrol 120 participants. Participants will be recruited from the local community in Shijingshan and Haidian Districts, Beijing, and allocated to either the intervention or control group using a 1:1 ratio. The intervention group will engage in 12 weeks of adaptive cognitive training, while the control group will receive 12 weeks of placebo cognitive training. A 24-week follow-up assessment will be conducted for all participants to evaluate the persistence of the effects. The primary outcome is the 12-week change in Montreal Cognitive Assessment (MoCA) Basic scores from baseline to the end of the intervention (12 weeks). Secondary outcomes include 6-week and 24-week changes in the MoCA from baseline; 6-week, 12-week and 24-week changes in Trail Making Test-A&B (TMT-A, TMT-B), Digit Symbol Substitution Test, the WHO/University of California at Los Angeles Auditory Verbal Learning Test and Boston Naming Test scores of cognitive functions; 6-week and 12-week changes in Geriatric Depression Scale, Generalised Anxiety Disorder-7 (GAD-7), Pittsburgh Sleep Quality Index and 12-week change in blood pressure (CONTENT-Hypertension) or fasting blood glucose and glycated haemoglobin (CONTENT-Diabetes) from baseline.
This study will adhere to the ethical principles outlined in the Declaration of Helsinki and comply with international standards for Good Clinical Practice. All participants will sign the informed consent at baseline. This study has been approved by the Ethics Committee of Plastic Surgery Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College (approval numbers: 2023-139 and 2024-162). The findings of the trials will be disseminated through publications in peer-reviewed scientific journals and presented at academic conferences.
To describe self-care behaviours and explore factors associated with self-care behaviours in older adults with multiple chronic conditions (MCCs).
The prevalence of MCCs is increasing in a rising trend. MCCs complicate the self-care behaviours of older adults. There is limited evidence regarding the factors associated with self-care behaviours in older adults with MCCs.
A cross-sectional design was adopted using the convenience sampling method.
Participants were recruited from a community health service centre. Measurements included the Self-Care of Chronic Illness Inventory, a single item for loneliness, the 6-item Lubben Social Network Scale, the 4-item Patient Health Questionnaire, the 15-item Tilburg Frailty Indicator, and a self-developed questionnaire for sociodemographic and disease-related characteristics. Descriptive statistics were used as appropriate. Multiple linear regression and multivariate logistic regression were adopted to examine the influencing factors.
A total of 223 participants were enrolled in this study. Among the 223 participants, 49.3%, 32.7% and 28.7% achieved a cut-off score of ≥ 70 in self-care maintenance, monitoring and management, respectively. The linear regression models indicated that smoking status, frailty and self-care confidence were significantly associated with self-care maintenance; education level, per capita monthly household income and self-care confidence were significantly associated with self-care monitoring; and employment status and self-care confidence were significantly associated with self-care management. In addition, multivariate logistic regression showed that living in cities or towns was significantly associated with higher odds of adequate self-care management.
Three domains of self-care behaviours were influenced by distinct factors, and self-care confidence demonstrated consistent associations with all three domains of self-care behaviours. Self-efficacy-focused interventions may have the potential to promote self-care behaviours in older adults with MCCs.
Healthcare providers need to take into account the pivotal factors influencing self-care behaviours of this cohort to deliver structured and effective education and support. Clinicians should consider adopting confidence-building strategies in routine education for this cohort.
We adhered to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines.

Thirst is the most common self-reported symptom in intensive care unit (ICU) patients. There is evidence that oral cooling interventions may alleviate thirst symptoms in ICU patients. However, the evidence needs to be critically evaluated.
To investigate the effect of oral cooling interventions on alleviating thirst symptoms of ICU patients and explore the effectiveness of different types of oral cooling by subgroup analysis.
The PubMed, Ovid Embase, the Cochrane Library, Wanfang Data and China National Knowledge Infrastructure databases were searched from inception to 29 October 2023. Randomised controlled trials (RCTs) that reported thirst intensity or thirst distress as outcomes were included. The certainty of the evidence was evaluated by the GRADE approach.
The meta-analysis comprised eight RCTs that included 813 ICU patients. The pooled analysis from eight RCTs showed that oral cooling interventions had significant beneficial effects on thirst intensity (weighted mean difference [WMD] = −2.73, 95% confidence interval [CI] = −3.62 to −1.85, p < 0.01; moderate certainty). The pooled analysis from four RCTs showed that oral cooling interventions could significantly lower the thirst distress scores (standardised mean difference = −0.80, 95% CI = −1.13 to −0.47, p < 0.01; low certainty). Subgroup analysis indicated that cold stimulation (WMD = −3.12) and cold combined with menthol stimulation (WMD = −1.72) could significantly lower the thirst intensity scores.
Oral cooling interventions including cold and menthol had beneficial effects on thirst intensity and thirst distress in ICU patients. The high heterogeneity in methods should be considered when interpreting the results.
This study provides references for the application of oral care strategy in the ICU care field, and encourages nurses to apply the oral cooling plan to improve patients' comfort.
This was a meta-analysis based on data from previous studies.

At-risk mothers experience disproportionately higher rates of antenatal depression and anxiety, which can hinder mother–infant bonding and adversely affect infant socioemotional development. Despite growing evidence on postpartum mental health, antenatal risk factors among psychosocially vulnerable mothers remain underexplored, particularly in multi-ethnic Asian settings.
To identify factors associated with antenatal depression, anxiety, and maternal–fetal bonding among at-risk mothers.
This cross-sectional observational study was nested within an ongoing randomised controlled trial. Two hundred at-risk mothers, defined as single, of low socioeconomic status, referred for psychosocial support, at risk of depression, with adverse childhood experiences, or with a fetus with a congenital malformation, were recruited from outpatient obstetric clinics between February and September 2024. Participants completed online self-administered questionnaires assessing antenatal depression, anxiety, perceived stress, social support, parenting self-efficacy, and maternal–fetal bonding. General Linear Models were used to analyse data and identify factors associated with depression, anxiety, and bonding.
Higher perceived stress was associated with increased depression (β = 0.28, p < 0.001) and anxiety (β = 1.28, p < 0.001) and poorer bonding (β = 0.08, p = 0.02), while greater social support predicted lower anxiety (β = −0.31, p < 0.001). Higher parenting self-efficacy was linked to stronger bonding (β = −0.09, p = 0.06). Younger mothers (β = −2.68, p = 0.025) and Indian mothers (β = 7.46, p = 0.017) were particularly vulnerable to anxiety, whereas post-secondary education was protective against depression (β = −1.44, p = 0.02). Model fit ranged from 0.14 to 0.65.
Perceived stress, social support, and parenting self-efficacy significantly influenced antenatal mental health and bonding in at-risk mothers. These findings underscore the need for culturally sensitive, nurse/midwife-led interventions that integrate early screening, stress reduction, and empowerment strategies within routine antenatal care to strengthen maternal mental health and early bonding outcomes.
(1) Nurses and midwives play a critical role in screening for antenatal depression and anxiety in mothers with risk profiles highlighted in this study. (2) Culturally responsive nursing practice that demonstrates sensitivity towards sociocultural pressures is needed to provide individualised care. (3) Integration of digital and community-based antenatal education programs could provide more equitable access to care for at-risk mothers who may face barriers to in-person care.
(1) Despite having a higher susceptibility for antenatal mental health conditions, risk factors for antenatal depression, anxiety, and maternal–infant bonding have been underexplored in at-risk mothers. (2) Antenatal stress and anxiety are universally associated with depression across risk groups, while maternal self-efficacy and perceived social support serve as key protective factors. (3) The findings from this study suggest the need for early screening and nurse-led interventions that support maternal parenting self-efficacy and stress management to improve maternal mental health outcomes among at-risk mothers.

Background and aimsChronic hepatitis B virus (HBV) infection remains a major global health burden and a leading cause of hepatocellular carcinoma (HCC). While cirrhosis is a well-established risk factor, the contributions of metabolic dysfunction-associated steatotic liver disease (MASLD) and cardiometabolic risk factors (CMRFs) are less clearly defined. This study aimed to evaluate the impact of MASLD and CMRFs on HCC risk in patients with chronic hepatitis B (CHB).
MethodsWe conducted a retrospective cohort study of CHB patients at Songklanagarind Hospital between 2011 and 2021, excluding those diagnosed with HCC within six months of follow-up. Clinical and imaging data were analyzed. Cumulative HCC incidence was estimated using Nelson-Aalen plots. Multivariable Cox regression was used to identify independent predictors. The aMAP score was evaluated in subgroups with obesity, CMRFs, and MASLD.
ResultsAmong 4,944 patients, 151 (3.1%) developed HCC. Cirrhosis (adjusted hazard ratio [aHR] 7.22), obesity (aHR 1.85), and male sex (aHR 1.78) were independent risk factors. Statin use (aHR 0.43), higher platelet count (aHR 0.62), and higher albumin (aHR 0.64) were protective. Diabetes and hypertension showed nonsignificant trends, and steatosis and dyslipidemia without statins were not significantly associated with HCC. Risk increased with the number of CMRFs. The aMAP score showed good discrimination in patients with obesity (C-index 0.82), CMRFs (0.79), MASLD (0.74), and in the non-cirrhotic MASLD and non-MASLD (0.69 and 0.71, respectively).
ConclusionsCirrhosis, male sex, and obesity were key HCC risk factors. The aMAP score effectively stratified HCC risk among metabolically at-risk CHB patients.
To explore community dwelling adults' lived experiences of participating in death café in Singapore.
A descriptive phenomenological study with Photovoice.
A purposive sample of community dwelling adults who participated in a community-based death café was recruited for this study. Data was collected through online individual semi-structured interviews. The Colaizzi's six-step descriptive phenomenological analysis was conducted for data analysis.
Twenty community dwelling adults who participated in a death café were recruited. Participants' experiences of the death café were expounded in four themes: appeals of attending death cafés, enabling features of death café, engaging in die-logues, and perceived impacts of death café on everyday lives. The participants were attracted to death cafés for various reasons including curiosity and grief. A comfortable environment, accompanied by open dialogues and refreshments, was credited as enablers for death conversations. Through these ‘die-logues’, the participants had a deeper understanding of death and began engaging in advance planning.
Death cafés provide a supportive environment for individuals to engage in death-related conversations that may not easily occur in daily life. By engaging in conversations about mortality within death cafés, participants are encouraged to take proactive steps towards advance planning.
Findings from this study can guide the development of community-based interventions by highlighting the essential components required for a death café tailored to the Asian context.
This study describes the community dwelling adults' lived experiences of participating in a death café. The findings from this study underscore the role of informal conversations about death as a tool to promote population health based palliative care initiatives such as overcoming death taboos and stimulating advance care planning among community dwelling adults.
The Consolidated Criteria for Reporting Qualitative Studies was used.

BackgroundTriggering receptor expressed on myeloid cells-1 (TREM-1) is a potent amplifier of inflammatory responses and plays a critical role in the pathogenesis of various infectious diseases. Notably, emerging evidence suggests that TREM-1 is also involved in the development and progression of cardiovascular diseases, such as atherosclerosis and atrial fibrillation. However, its role in myocardial ischemia/reperfusion (I/R) injury remains unclear. This study aimed to investigate the role of TREM-1 in myocardial I/R injury and to explore the potential underlying molecular mechanisms.
MethodsA hypoxia/reoxygenation (H/R) model was established using HL-1 cardiomyocytes subjected to 6 hours of hypoxia followed by 6 hours of reoxygenation. Pyroptosis levels were assessed by Hoechst-PI staining, lactate dehydrogenase (LDH) release assay, CCK-8 assay, and Western blot analysis. In vivo, a myocardial I/R injury model was established in C57BL/6 mice by subjecting them to 30 minutes of ischemia followed by 24 hours or 7 days of reperfusion. Evaluation was performed using TTC staining, Western blotting, echocardiography, histochemical staining, and immunohistochemistry.
ResultsIn this study, we found that TREM-1 expression was significantly upregulated in both in vitro and in vivo models of myocardial ischemia-reperfusion injury (MIRI). Pharmacological inhibition of TREM-1 by LR12 effectively reduced the levels of cardiomyocyte pyroptosis and suppressed activation of the NF-κB signaling pathway. In addition, LR12 treatment alleviated myocardial inflammation and fibrosis and improved left ventricular function in mice.Intervention experiments with MCC950, a specific NLRP3 inhibitor, confirmed that NLRP3 inhibition could mimic the anti-pyroptotic effect of LR12 and reduce the expression of pyroptosis-related proteins. Immunofluorescence experiments further verified that inhibition of NF-κB decreased NLRP3 expression, clarifying the association between TREM-1 downstream signals and NLRP3. Long-term follow-up experiments showed that LR12 treatment significantly reduced the area of myocardial fibrosis at 7 days after reperfusion.
ConclusionOur findings indicate that inhibition of TREM-1 alleviates cardiomyocyte pyroptosis during MIRI by suppressing activation of the NF-κB signaling pathway. Therefore, TREM-1 may represent a promising therapeutic target for the treatment of myocardial ischemia-reperfusion injury.
