The study aims to investigate patients' perceptions of recurrence risk associated with atrial fibrillation, with the goal of establishing a theoretical foundation for developing future measurement scale and intervention strategies.
A qualitative interview study.
Seventeen patients diagnosed with atrial fibrillation at a Grade-A tertiary hospital participated in semi-structured, in-depth interviews conducted between October and December 2024. Participants were selected via purposive sampling. The data were analysed employing thematic analysis in accordance with Colaizzi's method. The study adhered to the Consolidated Criteria for Reporting Qualitative Research checklist.
The perceptions of recurrence risk among patients with atrial fibrillation can be summarised into five themes: (1) perceived likelihood of recurrence, (2) perceived severity of recurrence, (3) perceived triggers of recurrence, (4) emotional reaction to recurrence, and (5) efficacy perception of managing recurrence risk.
Perceptions of recurrence risk among patients with atrial fibrillation are diverse and often underestimated due to limited knowledge and subjective symptom interpretation, affecting health behaviours. Understanding patients' subjective appraisals, emotions, and perceived efficacy is essential. Validated assessment tools and tailored risk communication may enhance self-management and support targeted interventions.
This study provides critical insights into how atrial fibrillation patients perceive their risk of recurrence. It also provides a theoretical foundation for creating validated assessment tools and tailoring individualised health education and intervention programmes.
Patients were involved in the study design, data collection, and interpretation of findings. Their contributions included providing feedback on the initial interview guide to ensure relevance and clarity, participating in in-depth interviews to share their lived experiences with atrial fibrillation recurrence, and offering reflections on key themes emerging from the data.
To assess career satisfaction among Chinese nurses, explore influencing factors, and examine the mediating role of role breadth self-efficacy (RBSE) in the relationship between subjective age and career satisfaction.
A multi-centre, cross-sectional study.
Between June and October 2024, 2033 questionnaires were distributed to nurses across seven geographic regions in China, collecting data on demographics, subjective age, RBSE, and career satisfaction. Descriptive statistics, Pearson correlation analysis, multiple linear stepwise regression, and path analysis were used to identify determinants of career satisfaction and test the mediating effect of RBSE.
The effective response rate was 97%. Chinese nurses reported moderate-to-high career satisfaction, younger subjective age relative to chronological age, and moderate RBSE levels. Multivariate linear regression analysis identified education level, work institution, salary, weekly working hours, subjective age, and RBSE as significant predictors of career satisfaction. Path analysis revealed a significant negative association between subjective age and career satisfaction (β = −0.23, p < 0.001), which was partially mediated by RBSE (indirect effect = −0.11, 95% CI: −0.18 to −0.05).
The career satisfaction of Chinese nurses is at a moderately high level; the influencing factors include the intensity of nursing work and salary levels. There is a certain difference between the subjective age and the chronological age of Chinese nurses. RBSE partly mediates the relationship between subjective age and career satisfaction.
Valuing the breadth of nurses' roles, self-efficacy, and subjective age may help improve job satisfaction.
What problem did the study address?: This study elucidates the present level of career satisfaction among nurses in China and the variables affecting it. What were the main findings?: The subjective age of Chinese nurses influences career satisfaction, with RBSE partly mediating the connection between subjective age and career satisfaction. Where and on whom will the research have an impact?: This study presents novel variables of subjective age and RBSE in the investigation of factors influencing career satisfaction among Chinese nurses, offering new avenues for enhancing career satisfaction in this demographic in the future.

BackgroundCurrent obesity treatments include behavioral interventions, pharmacotherapy and surgery. Recently, the combination of ‘medicinal food’ products such as the plant Crataegus pinnatifida and its interaction with the gut microbiota has shown promise as an alternative therapeutic strategy to treat obesity.
MethodsWe obtained secondary metabolites (SMs) of obesity-related gut microbiota and Crataegus pinnatifida from gutMGene database and NAPSS database. bioinformatics analysis was used to elucidate key target and signaling pathways, whereas molecular docking (MD), molecular dynamics simulation and quantum chemical calculations identified crucial SMs involved in these pathways. The toxicity and physicochemical properties of these SMs were also assessed.
ResultsPhosphoinositide-3-kinase regulatory subunit 1 (PIK3R1), a key mediator in the phosphoinositide 3-kinase (PI3K)/ Protein Kinase B (Akt) pathway that is crucial for regulating insulin signaling and adipogenesis, emerged as the central hub within the PPI network. Strong binders to PIK3R1 were predicted to be quercetin, kaempferol and naringenin chalcone, suggesting their potential as therapeutic agents to treat obesity.
ConclusionThe synergistic combination of Crataegus pinnatifida and the obesity-related gut microbiota holds promise as a novel therapeutic strategy for obesity by targeting PIK3R1 and modulating the PI3K/Akt signaling pathway. Further experimental validation is necessary to confirm these findings.
Care (Education) and Treatment Reviews (C(E)TRs) are intended to reduce unnecessary psychiatric hospital admission and length of stay for people with intellectual disability and autistic people. The use and impact of C(E)TRs have not been systematically evaluated since their introduction in England in 2015. The aims of this study are to describe the demographic and clinical profiles of people who receive a community C(E)TR and to investigate their effects on admission, length of hospital stay and clinical and functional change.
We will conduct a retrospective cohort study using de-identified data from electronic health records derived from two large National Health Service mental health providers in London, England, including one replication site. Data will be extracted using the Clinical Record Interactive Search (CRIS) tool for all people with recorded intellectual disability and/or autism who received mental healthcare from 2015. We will identify community C(E)TR events using keyword searches. Community C(E)TRs will be examined in two ways: (1) In a community cohort, we will capture data in the 6-month periods before and after a community C(E)TR and compare this to a matched control group and (2) In a hospital cohort, we will compare groups who did and did not receive a community C(E)TR prior to their admission. We will describe the socio-demographic and clinical profiles of each group and their health service use, and compare C(E)TR and no C(E)TR groups using t-tests (or a non-parametric equivalent). The primary outcomes are admission to a psychiatric hospital (community cohort) and length of psychiatric hospital admission and clinical change (hospital cohort). Admission to psychiatric hospital will be estimated using propensity score weighting and difference-in-differences methods. Cox’s proportional hazard model will be used for length of hospital admission and repeated-measures analysis of variance (ANOVA) will be used to assess clinical change.
Use of CRIS to examine de-identified clinical data for research purposes has overarching ethical approval. This study has been granted local approval by the South London and Maudsley CRIS Oversight Committee. Findings will be disseminated in an open-access peer-reviewed academic publication, at conference presentations, and to service users and carers in accessible formats.

BackgroundSarcopenia is an age-associated disorder characterized by a progressive decline in skeletal muscle mass, strength, and physical function. The condition is linked to low levels of anabolic hormones such as insulin-like growth factor 1 (IGF-1), with its downstream phosphatidylinositol 3 kinase (PI3K)/ protein kinase B (AKT)/ forkhead box protein O3 (FOXO3) signaling pathway. There is growing evidence that resistance training (RT) or vibration training (VT) could improve physical functioning in individuals with sarcopenia. However, the related physiological influence of exercise on sarcopenia remains elusive.
MethodThis prospective randomized controlled trial will be conducted among 96 participants, aged between 65 and 80 years. In participants, sarcopenia diagnosis will be confirmed based on the Asian Working Group for Sarcopenia criteria, and participants will be randomized into either control, RT, VT, or RVT (combined RT and VT) groups. The intervention will last 12 weeks, with assessments performed at baseline, 12 weeks (after intervention), and 24 weeks (follow-up). The primary outcomes will include skeletal muscle mass, handgrip strength, and gait speed. Secondary outcomes comprise IGF-1 concentrations, PI3K/AKT and FOXO3 protein activity, quality of life, and timed-up-and-go test performance assessments.
DiscussionThis clinical study aims to elucidate the potential modulation of molecular mechanisms in vivo for combined RT and VT in sarcopenia patients and to identify the effects of the intervention on physical function.

To systematically identify and appraise existing risk prediction models for EN aspiration in adult inpatients.
A systematic search was conducted across PubMed, Web of Science Core Collection, Embase, Cochrane Library, CINAHL, China National Knowledge Infrastructure (CNKI), Wanfang Database, China Biomedical Literature Database (CBM) and VIP Database from inception to 1 March 2025.
Systematic review of observational studies.
Two researchers independently performed literature screening and data extraction using the Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies (CHARMS). The Prediction Model Risk of Bias Assessment Tool (PROBAST) was employed to evaluate both the risk of bias and the clinical applicability of the included models.
A total of 17 articles, encompassing 29 prediction models, were included. The incidence of aspiration was 9.45%–57.00%. Meta-analysis of high-frequency predictors identified the following significant predictors of aspiration: history of aspiration, depth of endotracheal intubation, impaired consciousness, sedation use, nutritional risk, mechanical ventilation and gastric residual volume (GRV). The area under the curve (AUC) was 0.771–0.992. Internal validation was performed in 12 studies, while both internal and external validation were conducted in 5 studies. All studies demonstrated a high risk of bias, primarily attributed to retrospective design, geographic bias (all from different parts of China), inadequate data analysis, insufficient validation strategies and lack of transparency in the research process.
Current risk prediction models for enteral nutrition-associated aspiration show moderate to high discriminative accuracy but suffer from critical methodological limitations, including retrospective design, geographic bias (all models derived from Chinese cohorts, limiting global generalisability) and inconsistent outcome definitions.
Recognising the high bias of existing models, prospective multicentre data and standardised diagnostics are needed to develop more accurate and clinically applicable predictive models for enteral nutrition malabsorption.

To evaluate the research capability of clinical nurses in China and identify the determinants associated with their capability.
As nursing evolves into an increasingly independent discipline, the research capability of clinical nurses has become critical for the development of the profession, advancing evidence-based practice and improving patient care quality.
A multicentre cross-sectional survey was conducted using convenience sampling from September 2023 to February 2024, among clinical nurses in tertiary hospitals across three provinces in China. The Nursing Research Capability Self-Assessment Scale was used to assess the research capability of the nurses. Chi-square tests, one-way analysis of variance and multiple linear regression were used to examine factors associated with research capability. The Strengthening the Reporting of Observational Studies in Epidemiology was followed.
A total of 1074 clinical nurses participated. The mean research capability score was 89.11 ± 27.69, reflecting a moderate level of research capability. However, two dimensions of research questions and literature review received lower scores. Multiple linear regression analysis identified that education level, professional title, administrative position and nursing job title (all p < 0.05) were independent predictors of research capability.
Clinical nurses exhibit moderate research capability, with notable deficiencies in formulating research questions and conducting literature reviews. Key factors influencing research capability include education, professional title, administrative position, and job title. Targeted training and development programmes should address these factors to enhance nurses' research competence and advance nursing science.
To describe the perspectives of individuals receiving haemodialysis regarding health literacy in fluid management.
A qualitative descriptive approach using directed content analysis of interviews from an explanatory mixed methods study.
Semi-structured individual interviews were conducted from September 2020 to February 2021 with 28 individuals receiving haemodialysis who had attended a prior quantitative study. A directed qualitative content analysis approach was used to identify categories and subcategories emerging from the data.
Six categories of health literacy were identified: (1) active health management, (2) engagement with healthcare providers, (3) understanding and support from healthcare providers, (4) social support, (5) health information literacy and (6) navigation of the healthcare system.
Based on their real-life experience, individuals receiving haemodialysis have unique health literacy needs regarding fluid management. A comprehensive understanding of these unique needs is crucial in creating person-centered interventions to address inadequate fluid restriction.
Interventions to address inadequate fluid restriction should be person-centered, considering each individual's unique health literacy needs. This involves conducting a comprehensive assessment of individuals' health literacy needs, empowering individuals to actively engage in health, engaging the entire support network and facilitating health information literacy in line with individuals' preferences.
This study offers detailed insights into the health literacy needs related to fluid management in individuals undergoing haemodialysis. The findings could inform the development of person-centered fluid management strategies for these individuals.

To quantitatively analyze the coupling relationships between railway safety risk factors, identify key factors contributing to railway accidents, and develop scientific strategies for accident prevention, this study introduces a complex network-based N-K model to investigate the coupling relationships of railway safety risk factors. First, we identified 18 railway safety risk factors by analyzing case data from railway accidents. The occurrence probabilities and coupling values of these risk factors were then calculated using the N-K model. Subsequently, based on the constructed railway safety risk complex network, reachability and centrality analyses were performed to determine the key factors of railway safety risk. Results indicate that the occurrence of railway accidents is directly proportional to the risk coupling value; the greater the number of coupling factors, the higher the risk value. The coupling of personnel factors and equipment factors is particularly prone to leading to railway accidents. Conversely, effective management of the coupling between personnel and equipment factors can significantly reduce the likelihood of accidents. Inadequate maintenance and unsafe human behavior were identified as critical factors contributing to railway accidents and should be prioritized in prevention efforts.by Jingwei Song, Alexander A.

Hemolymph is vital for bivalves, contributing to their innate immune system, nutrient transport, waste elimination, and hormone regulation. Yet, traditional sampling methods are often invasive or fatal to the organisms. In this study, we evaluated the effects of repeated, non-lethal hemolymph sampling on adult Pacific oysters (Magallana gigas). Five- year-old oysters were relaxed with magnesium sulphate, and hemolymph was extracted from half of the individuals, while the other half with relaxation served as controls. Sampling took place during gonad maturation in two groups: one laboratory conditioned (approximately three months in indoor tanks with controlled environment), and one naturally conditioned (approximately seven months at the bay in Yaquina Bay, Oregon, USA). Total mortalities ranged from 10% in the laboratory groups (after four samplings) and 22% (after seven samplings) in the natural groups; most of the mortalities took place after the last sampling. Sex ratio was similar between the sampled (66%) and control groups (63%) in the laboratory setting. In the natural setting, the final sex ratio was male biased in the group that was repeatedly sampled for hemolymph (58%) compared to the non-sampled controls (28%). Our findings highlight that repeated hemolymph sampling can be performed with minimal mortality, allowing non-lethal monitoring of hemolymph physiology over time.by Mengqi Yuan, Yajing Yuan, Xiangqun Zhang, Zhenghao Zhu, Chenxi Zhao, Xiangqian Gao, Genyuan Du
Millimeter-wave (mmWave) radar has become an important research direction in the field of object detection because of its characteristics of all-time, low cost, strong privacy and not affected by harsh weather conditions. Therefore, the research on millimeter wave radar object detection is of great practical significance for applications in the field of intelligent security and transportation. However, in the multi-target detection scene, millimeter wave radar still faces some problems, such as unable to effectively distinguish multiple objects and poor performance of detection algorithm. Focusing on the above problems, a new target detection and classification framework of S2DB-mmWave YOLOv8n, based on deep learning, is proposed to realize more accuracy. There are three main improvements. First, a novel backbone network was designed by incorporating new convolutional layers and the Simplified Spatial Pyramid Pooling - Fast (SimSPPF) module to strengthen feature extraction. Second, a dynamic up-sampling technique was introduced to improve the model’s ability to recover fine details. Finally, a bidirectional feature pyramid network (BiFPN) was integrated to optimize feature fusion, leveraging a bidirectional information transfer mechanism and an adaptive feature selection strategy. A publicly available 5-class object mmWave radar heatmap dataset, including 2,500 annotated images, were selected for data modeling and method evaluation. The results show that the mean average precision (mAP), precision and recall of the S2DB-mmWave YOLOv8n model were 93.1% mAP@0.5, 55.8% mAP@0.5:0.95, 89.4% and 90.6%, respectively, which is 3.3, 1.6, 4.5 and 7.7 percentage points higher than the baseline YOLOv8n network without increasing the parameter count.To explore how the mentor-student relationship affects nursing graduate students' satisfaction with mentors, as well as how mentoring mode and learning motivation work together.
A multi-centre cross-sectional study.
Thirty universities and colleges in eastern, central and western China.
A total of 826 nursing graduate students from thirty universities and colleges participated in this study in April 2024.
Data were collected using the general information questionnaire, mentor-student relationship entry, mentoring mode questionnaire, graduate students' satisfaction item and learning motivation scale. Data were analysed using SPSS 25.0 software. The PROCESS macro-plugin and the bootstrap method were utilised to examine the mediating and moderating effects of learning motivation and mentoring mode.
There was a positive correlation between nursing graduate students' satisfaction with mentors and the mentor-student relationship (r = 0.377, p < 0.001), learning motivation (r = 0.600, p < 0.001), and mentoring mode (r = 0.292, p 0.001). Learning motivation exerted a partial mediation effect between the mentor-student relationship and graduate students' satisfaction with mentors (mediation effect value = 0.182, 95% CI = 0.148–0.218). Mentoring mode moderated the path of learning motivation in the mentor-student relationship (interaction term coefficient = 0.031, 95% CI = 0.005–0.056).
Mentor-student relationship positively predicted nursing graduate students' satisfaction with mentors significantly. Learning motivation played a partial mediating effect between mentor-student relationship and graduate students' satisfaction with mentors and mentoring mode moderated between mentor-student relationship and learning motivation pathways. Therefore, cultivating positive teacher/helpful friend relationship, boosting students' learning motivation and improving mentoring mode techniques can all increase nursing graduate students' satisfaction with mentors.

To systematically analyse international empirical literature and establish a comprehensive understanding of the push and pull factors influencing retention and turnover among mid-career nurses.
An integrative review.
PubMed, Web of Science, Scopus, EMBASE (Ovid), and CINAHL (EBSCO) were searched for studies published between January 2001 and November 2024.
An integrative literature review was conducted following the five-step process outlined by Whittemore and Knafl. Articles were screened by title, abstract, and full text based on predefined inclusion and exclusion criteria. The quality of eligible studies was assessed using the Mixed Methods Appraisal Tool (MMAT). Data were extracted and synthesised narratively, and the findings were presented according to the socio-ecological framework.
A total of 1930 studies were identified, with 14 included for analysis: 10 qualitative, 3 quantitative, and 1 mixed-methods study. Guided by the socio-ecological framework, four themes and 10 subthemes emerged: (1) Intrapersonal (professional knowledge/skills, health issues, work-family balance); (2) Interpersonal (professional collaborative relationships, supervisor support); (3) Organisational (organisational characteristics, work characteristics, career development); and (4) Societal (salary/benefits, Social/governmental recognition).
This review reveals the heterogeneity of research on this topic and confirms previous findings. It identifies certain push-and-pull factors common to nurses across all stages of their careers. However, mid-career nurses face unique challenges, including more complex healthcare demands, declining health status, growing family caregiving responsibilities, unclear organisational roles, underutilisation of professional skills, career stagnation, and limitations on salary growth. These findings highlight the need for tailored retention strategies for mid-career nurses.
A “one-size-fits-all” retention strategy does not meet the needs of all nurses. To improve nurse retention rates, it is essential to address the shifting demands and priorities that arise as nurses reassess and transition through different career stages. For mid-career nurses, acknowledging and valuing their expertise and capabilities, providing sufficient resources, and fostering a supportive work environment that promotes career development may be effective strategies for retaining these experienced professionals.

To explore the perceptions and experiences of parents caring for children with paediatric feeding disorders requiring feeding tubes (PFD-T).
A descriptive qualitative approach was adopted in this study.
Using purposive sampling, 12 parents were recruited from paediatric inpatient wards and the outpatient paediatric feeding clinic at a tertiary public hospital in Singapore. Data collection was done from July to December 2024. Semi-structured one-on-one interviews were conducted with the parents (fathers or mothers) until data saturation. Thematic analysis was used to identify themes from the interview content.
A total of three themes and six subthemes were identified, encapsulating the challenges experienced by parents with caregiving and feeding tube management, as well as the sources of support they had. The themes are: (1) A sense of community, (2) Grieving over the loss of normalcy and (3) Facing the unknown.
Parents in this study felt supported being in a community of other parents with children who have PFD-T. It enabled them to gain valuable information and offered them a space where they felt understood. At the same time, they expressed feelings of guilt and isolation, as the caregiving demands led to limited capacity to cater to or interact with other loved ones. Additional challenges parents faced included transitioning between types of feeding tubes and insufficient support from healthcare professionals.
Ethical approval was obtained from the National Health Group Domain Specific Review Board (DSRB 2024/00064) on 8 May 2024.

To develop and validate a machine learning-based risk prediction model for delirium in older inpatients.
A prospective cohort study.
A prospective cohort study was conducted. Eighteen clinical features were prospectively collected from electronic medical records during hospitalisation to inform the model. Four machine learning algorithms were employed to develop and validate risk prediction models. The performance of all models in the training and test sets was evaluated using a combination of the area under the receiver operating characteristic curve (AUC), accuracy, sensitivity, Brier score, and other metrics before selecting the best model for SHAP interpretation.
A total of 973 older inpatient data were utilised for model construction and validation. The AUC of four machine learning models in the training and test sets ranged from 0.869 to 0.992; the accuracy ranged from 0.931 to 0.962; and the sensitivity ranged from 0.564 to 0.997. Compared to other models, the Random Forest model exhibited the best overall performance with an AUC of 0.908 (95% CI, 0.848, 0.968), an accuracy of 0.935, a sensitivity of 0.992, and a Brier score of 0.053.
The machine learning model we developed and validated for predicting delirium in older inpatients demonstrated excellent predictive performance. This model has the potential to assist healthcare professionals in early diagnosis and support informed clinical decision-making.
By identifying patients at risk of delirium early, healthcare professionals can implement preventive measures and timely interventions, potentially reducing the incidence and severity of delirium. The model's ability to support informed clinical decision-making can lead to more personalised and effective care strategies, ultimately benefiting both patients and healthcare providers.

Volumetric modulated arc therapy (VMAT) for lung cancer involves complex multileaf collimator (MLC) motion, which increases sensitivity to interplay effects with tumour motion. Current dynamic conformal arc methods address this issue but may limit the achievable dose distribution optimisation compared with standard VMAT. This study examined the clinical utility of a VMAT technique with monitor unit limits (VMATliMU) to mimic conformal arc delivery and reduce interplay effects while maintaining plan quality. VMATliMU was implemented by applying monitor unit limitations during VMAT reoptimisation to minimise MLC encroachment into target volumes. Using mesh-type reference computational phantom CT images, treatment plans were generated for a simulated stage I lung cancer case prescribed to 45 Gy in three fractions. VMATliMU, conventional VMAT, VMAT with leaf speed limitations, dynamic conformal arc therapy, and constant dynamic conformal arc therapy were compared. Plans were optimised for multiple isodose line prescriptions (50%, 60%, 70%, 80%, and 90%) to investigate the impact of dose distribution. Evaluation parameters included MLC positional accuracy using area difference ratios, dosimetric indices, gradient metrics, and organ-at-risk doses. VMATliMU prevented MLC encroachment into the internal target volume across 60%–90% isodose lines, showing superior MLC accuracy compared with other methods. At the challenging 50% isodose line, VMATliMU had 4.5 times less intrusion than VMAT with leaf speed limits. VMAT plans had better dosimetric indices than dynamic conformal arc plans. VMATliMU reduced monitor units by 5.1%–19.2% across prescriptions. All plans met the clinical dose constraints, with the aortic arch below tolerance and acceptable lung doses. VMATliMU combines VMAT’s dosimetric benefits with the dynamic conformal arcs’s simplicity, minimising MLC encroachment while maintaining plan quality. Reduced monitor units lower low-dose exposure, treatment time, and interplay effects. VMATliMU is usable in existing planners with monitor unit limits, offering a practical solution for lung stereotactic body radiation therapy.Physiological, psychological, and social changes may make older adults more vulnerable to stressors and lead to adverse health outcomes. It remains unclear whether interventions targeting coping strategies in older adults are effective.
This study aimed to systematically review and summarize existing interventions aimed at improving coping strategies in older adults and analyze intervention effectiveness.
A systematic search was conducted using PubMed, EMBASE, Web of Science, Cochrane, CINAHL, PsycINFO, CNKI, SinoMed, VIP, and WanFang databases for randomized controlled trials (RCTs) and quasi-experimental studies. Two researchers independently performed literature screening, quality assessment, and data extraction.
A total of 9 studies were included, comprising 7 RCTs and 2 quasi-experimental studies. Meta-analysis revealed that the interventions significantly enhanced the use of problem-focused coping strategies among older adults (SMD = 0.37, 95% CI: 0.12 ~ 0.63, p = 0.005, I 2 = 39%). However, there was no significant effect on emotion-focused coping strategies (SMD = −0.07, 95% CI [−0.62, 0.48], p = 0.80, I 2 = 76%). Moreover, no significant statistical differences were observed between the intervention group and the control group in terms of positive (SMD = 1.49, 95% CI [−0.23, 3.21], p = 0.09, I 2 = 98%) or negative coping strategies (SMD = −0.76, 95% CI [−1.79, 0.28], p = 0.15, I 2 = 96%).
Interventions targeting coping strategies can significantly improve the problem-focused coping strategies of older adults. It is crucial to help older adults accurately recognize daily stressors, acquire emotional regulation strategies, and enhance coping skills. More large-scale RCTs are needed to draw more robust conclusions.
