The treatment of chronic wounds in the Aged is often difficult. Masquelet technique is used for the treatment of infected large segmental bone defects as it provides an adequate blood supply for bone and soft tissue reconstruction. In this study, a two-stage wound management strategy was used, consisting of covering the initial wound with bone cement and skin grafting under induced membranes. From September 2020 to September 2022, 20 Aged patients with chronic refractory wounds of the lower extremities with exposed bone or tendons were recruited in the Department of Wound Repair Surgery of the Second Affiliated Hospital of Wenzhou Medical University. Each patient was reconstructed according to a two-stage process. In the first stage, while treating the patient's underlying disease, several debridements were first performed on the wound; subsequently, the Masquelet technique was applied to seal the wound with antibiotic bone cement. Four to 6 weeks later, the second stage was initiated—after confirming the sufficient formation of wound induced membranes, the bone cement was removed, and free skin grafts were finally used to cover the chronic refractory wounds on the extremities. The area of the defects ranged from 4.5 × 3.0 cm to 15.0 × 6.0 cm, and all soft tissue defects were associated with tendon or bone exposure. After the surgery, patients attended regular outpatient visits and were followed up by telephone and video to observe the healing of the wounds and whether there were any complications in the donor site. The Lower Extremity Function Scale (LEFS) score was used to evaluate the functional recovery of the lower extremities. We found that all implants survived without necrosis or infection. All 20 cases were followed up regularly after surgery for 3 to 12 months, with a mean of 7.6 months. In the first stage, Induced Membranes induction was performed 1–4 times, with an average of (1.3 ± 0.7) times, and in the second stage, free skin grafting was performed on the induction membrane, and all 20 cases of skin grafting survived without necrosis or infection; the appearance and texture of the skin in the grafted area were satisfactory, and the postoperative LEFS score was (69.83 ± 10.82). Finally, our strategy for the management of chronic refractory wounds in the Aged can achieve satisfactory clinical results, reduce surgical risk, be simple and reliable, and be an effective addition to the repair modality.
Non-communicable diseases (NCDs) currently contribute to over 50% of the global disease burden. Digital tools bear the potential to mitigate the risk of NCDs by facilitating personalised, preventive healthcare. It is therefore pertinent to examine the specific components that contribute to the success or constrain the impact of digital health interventions (DHIs), with particular attention to the sustainability of their long-term effects. Additionally, it is important to provide an up-to-date perspective on emerging interventions and technologies that have not yet been comprehensively addressed in the literature. This protocol defines the methodology for an umbrella review to synthesise the available high-quality evidence from systematic reviews and meta-analyses regarding effectiveness of DHIs in influencing the primary prevention of NCDs.
Using a rigorous search strategy, the subsequent databases will be searched in December 2025: MEDLINE, Web of Science, CINAHL, Embase, Scopus and Epistemonikos. Following the Joanna Briggs Institute (JBI) methodology, the selected literature will be screened based on predefined inclusion criteria. This includes systematic reviews and meta-analyses published within the last 5 years, without restrictions on country or language, that evaluate the effectiveness of any DHI aimed at the primary prevention of NCDs. Suitable full-text articles will be extracted by four researchers and independently assessed for methodological quality by two researchers using the AMSTAR-2 (A Measurement Tool to Assess Systematic Reviews) tool. The results will be presented in a summary table aligned with the review question and subquestions, accompanied by a narrative synthesis that explores the findings and their relevance to the research aims.
Ethical approval is not required as no primary data will be collected. The findings of this umbrella review will be published in a peer-reviewed journal and presented at academic conferences.

Due to the diversification of media functions of mobile phones, users can make calls and access the internet simultaneously, which has significantly increased the usage time of mobile phones. The exposure dose of the users in the combined electromagnetic fields (EMF) should be further quantified to better evaluate the public exposure safety. Different from most conventional EMF safety studies that only focus on a single frequency, this work not only discusses the mobile phone simultaneously operated in fourth-generation (4G) and fifth-generation (5G) mobile communications radiation impact on users, but also verifies that the miniaturized mobile phone multiple-input multiple-output (MIMO) antenna array can significantly reduce the specific absorption rate (SAR) absorbed by users. In this article, a miniaturized mobile phone MIMO antenna array is employed as the radiation source, and multi-pose human models are established to simulate the practical utilization of a smartphone. A systematic analysis of the SAR absorbed by the human model is conducted in both single and combined EMF scenarios. The results indicate that the peak SAR in various tissues under multi-frequency exposure is 1.02 to 15.85 times higher than that under single-frequency exposure.by Lauren Riehm, Keean Nanji, Moiz Lakhani, Evelina Pankiv, Dean Hasanee, Wesla Pfeifer
PurposeLarge language models (LLMs) have the potential to change medical education. Whether LLMs can generate multiple-choice questions (MCQs) that are of similar quality to those created by humans is unclear. This investigation assessed the quality of MCQs generated by LLMs compared to humans.
MethodsThis review was registered with PROSPERO (CRD42025608775). A systematic review and frequentist random-effects network meta-analysis (NMA) or pairwise meta-analysis was performed. Ovid MEDLINE, Ovid EMBASE, and Scopus were searched from inception to November 1, 2024. The quality of MCQs was assessed with seven pre-defined outcomes: question relevance, clarity, accuracy/correctness; distractor quality; item difficulty analysis; and item discrimination analysis (point biserial correlation and item discrimination index). Continuous data were transformed to a 10-point scale to facilitate statistical analysis and reported as mean differences (MD). The MERSQI and the Grade of Recommendations, Assessment, Development and Evaluation (GRADE) NMA guidelines were used to assess risk of bias and certainty of evidence assessments.
ResultsFive LLMs were included. NMA demonstrated that ChatGPT 4 generated similar quality MCQs to humans with regards to question relevance (MD −0.13; 95% CI: −0.44,0.18; GRADE: VERY LOW), question clarity (MD −0.03; 95% CI: −0.15,0.10; GRADE: VERY LOW), and distractor quality (MD −0.10; 95% CI: −0.24,0.04; GRADE: VERY LOW); however, MCQs generated by Llama 2 performed worse than humans with regards to question clarity (MD −1.21; 95% CI: −1.60,-0.82; GRADE: VERY LOW) and distractor quality (MD −1.50; 95% CI: −2.03,-0.97; GRADE: VERY LOW). Exploratory post-hoc t-tests demonstrated that ChatGPT 3.5 performed worse than Llama 2 and ChatGPT 4 with regards to question clarity and distractor quality (p Conclusion
ChatGPT 4 may create similar quality MCQs to humans, whereas ChatGPT 3.5 and Llama 2 may be of worse quality. Further studies that directly compare these LLMs to human-generated questions and administer MCQs to students are required.

PurposeThe aim of this study is to evaluate the changes of white matter microstructure in breast cancer patients before and after chemotherapy based on automated fiber quantification (AFQ),as well as determine if these dispersion indexes are significantly correlated with clinical data.
Materials and MethodsTwenty-four breast cancer patients scheduled for chemotherapy were enrolled. Diffusion tensor imaging (DTI), neuropsychological tests and self-report measures, and hematological tests were conducted before chemotherapy(time 0,T0) and within one week after chemotherapy(time 1,T1). AFQ was used to track 20 fiber tracts in the brain. The correlation between average abnormal tracts and changes in neuropsychological tests and self-report measures and blood indicators was analyzed.
ResultsCompared to T0, subjects at T1 showed decreased scores on the verbal fluency test; increased scores on the self-rating anxiety scale(SAS)and self-rating depression scale (SDS). Estrogen concentration was lower while luteinizing hormone(LH), follicle-stimulating hormone, and triglyceride levels were higher. Mean fractional anisotropy (FA) value decreased in the right cingulum cingulate(CGC)while mean radial diffusivity (RD) increased in the right CGC; mean axial diffusivity (AD) value decreased in callosum forceps major and callosum forceps minor. Changes in FA with in the right CGC were positively correlated with changes in SDS and LH, while changes in RD with in the right CGC were negatively correlated with changes in SDS and LH.
ConclusionEarly changes observed in brain white matter fiber tracts, along with persistent hormone and triglyceride metabolism disorders, could potentially serve as neurobiological markers for monitoring chemotherapy-induced cognitive impairment.
Mobilisation and mobility in clinical settings are essential to the recovery process after surgery and trauma-related hospital admission. In addition to personal support from physiotherapists and nursing staff, aids such as walkers are applied. Walkers equipped with smart features have the potential to benefit geriatric patients by facilitating routine clinical workflows and, where appropriate, by providing health professionals with information on gait patterns and vital parameters.
The overarching goal of this project is to develop an innovative smart walker for clinical use, guided by three objectives: (a) Identify the feature requirements of the smart walker from the perspectives of patients and health professionals, (b) Co-design the smart walker using a user-centred approach involving older patients, health professionals and clinical engineers and (c) Pilot-test the smart walker in real time with older patients admitted to German clinics.
We will employ a three-phased exploratory sequential mixed-methods approach in this project. Phase I explores potentially useful characteristics of a smart walker via a scoping literature review (part 1 of phase I) and a qualitative interview and observational study, including questionnaires on sociodemographic data and technology readiness, involving four to six patients and four to eight nurses and physiotherapists (part 2 of phase I). Phase II focuses on developing and validating a smart walker through a user experience design, with at least three iterative test cycles involving a minimum of three asymptomatic participants and three to seven potential users in each cycle. Phase III comprises a pilot study conducted at a University Hospital in Germany involving at least twelve patients. Data integration takes a data-building approach, combining qualitative and quantitative results in the final analysis to generate a comprehensive understanding and to create and refine insights into the feature needs and use of a smart walker by patients.
The study was approved by the Ethics Committee of University Medicine Halle, Germany (Approval No. 2025-032; date of approval: 03/04/2025). Study results will be disseminated through peer-reviewed journals and conferences.
The study protocol was registered at the Open Science Framework Platform (OSF, register number: 10.17605/OSF.IO/CTPF4).
Obesity is a key risk factor for kidney stones (KS). The body roundness index (BRI) is a newer measure for assessing body fat distribution. Studies in Western populations have linked BRI to KS risk, but no such research has been conducted in Asian populations. This study aimed to examine the association between BRI and KS in Chinese adults.
This cross-sectional study included 78 386 Chinese adults who underwent abdominal ultrasound examination. Data on demographic characteristics, clinical history and laboratory parameters were collected. The diagnosis of KS was based on the ultrasound findings. Multivariable logistic regression examined the association between the BRI and KS risk. The analysis incorporated subgroup analyses, dose-response relationship assessment and mediation analysis.
Multivariable-adjusted logistic regression analyses revealed that the BRI was significantly positively correlated with KS risks in both genders, with a more pronounced effect observed in males (OR 1.16, 95% CI 1.12 to 1.20) compared with females (OR 1.11, 95% CI 1.04 to 1.20). Participants in the highest BRI tertile had a 47% and 23% higher KS risk in males and a 23% higher KS risk in females, respectively, compared with the lowest tertile. Dose-response analysis showed a non-linear relationship between BRI and KS risk in both males and females. Mediation analysis indicated that low-density lipoprotein cholesterol accounted for 7.2% of the association in females, whereas hypertension (14.8%) and uric acid (12.5%) were the primary mediating factors in males. Subgroup analyses confirmed that the association was modified by age and diabetes in females and by diabetes in males.
The findings demonstrate a significant association between elevated BRI and increased KS risk, underscoring the necessity of implementing gender-specific strategies and considering mediating factors in KS prevention.

IntroductionSurgical staplers are essential tools in minimally invasive surgery (MIS), enabling tissue division, hemostasis, and secure anastomoses. With the growth of robotic-assisted surgery, robotic staplers such as SureForm have recently become available. These staplers offer precise articulation and real-time tissue compression monitoring. However, the clinical advantages of robotic staplers over bedside staplers remain uncertain. Studies show mixed results across specialties, mainly due to small sample sizes, outdated data, and data heterogeneity. This study protocol proposes a series of future analyses that will evaluate the clinical outcomes and resource utilization of robotic versus bedside staplers in robotic-assisted surgeries across multiple specialties using recent real-world data.
Methods and analysisThis retrospective cohort study will use data from the Premier Healthcare Database (PHD), a large hospital-based database covering patients with varied payers across the United States. Adult patients (≥18 years) who underwent elective, fully robotic-assisted lung, colorectal, gastric, or bariatric surgeries from 2019 to 2023 will be included. Each surgical specialty will be analyzed in a separate paper. Patients will be categorized into two groups based on the type of surgical stapler used: robotic staplers (SureForm) and bedside staplers (manual or powered). The primary outcome will be postoperative leak (air leak for lung resection; anastomotic leak for colorectal, gastrectomy, and bariatric). Key secondary outcomes are other complications, conversion to open surgery, operative time, transfusion requirements, length of stay (LOS), and cost. Overlap weighting will be applied to minimize bias.
DisseminationResults will be disseminated through peer-reviewed surgical journals and presentations at relevant surgical meetings.
To summarise the incidence rate and identify the risk factors for oral endotracheal tube-related mucous membrane pressure injury (OETMMPI) in critically ill patients.
This systematic review and meta-analysis followed the PRISMA 2020 requirements. We searched the databases PubMed, Embase, Web of Science, the Cochrane Library, WanFang, China Science and Technology Journal Database (VIP), China National Knowledge Infrastructure (CNKI) and China Biomedical Literature Database (SinoMed) from conception to July 3, 2025. Two independent researchers read the publications, assessed them and extracted data. Stata 18.0 software was used to conduct the analyses.
This meta-analysis comprised 16 observational studies. Two studies recorded the number of days of tracheal intubation rather than the number of patients who required it, which totaled 274 days. The remaining 14 trials included a total of 6768 adult patients. The incidence rate of OETMMPI was 28.9% (95% CI = 0.177–0.417). Risk factors include tracheal catheter indwelling time (OR = 1.13), APACHE II score (OR = 1.39), use of hard bite blocks (OR = 1.88), prone ventilation (OR = 3.95), diabetes history (OR = 4.86), vasoconstrictor medication use (OR = 2.11) and albumin level (OR = 0.50).
The incidence rate of OETMMPI is relatively high in critically ill patients, and there are many influencing factors. Nursing staff should enhance their awareness of OETMMPI, accurately identify high-risk groups and risk factors, and formulate early, full-course, meticulous and personalised intervention measures for critically ill patients to prevent OETMMPI.
OETMMPI in critically ill patients brings pain to the patients, increases the risk of infection and affects the prognosis of the disease. Therefore, medical staff should regularly assess and address it. This study also identified specific related factors, and these results provided valuable insights for the ICU medical team to identify high-risk patients and offer personalised intervention measures to reduce their occurrence.
Smoking cessation is a pressing public health concern. Behavioral therapy has been widely promoted as a means to aid smoking cessation. Acceptance and commitment therapy (ACT), based on the principles of cognitive behavioral therapy, can help participants accept, rather than suppress, the physical and emotional experiences and thoughts associated with not smoking, identify experiential avoidance behaviors, strengthen the determination to quit, and ultimately commit to adaptive behavioral changes guided by smoking-cessation-related values, thereby achieving the goal of quitting smoking.
To assess the effects of ACT compared with other smoking cessation interventions by examining three key outcomes: cessation rates, smoking behaviors, and psychological outcomes.
We searched 8 databases and 2 registration platforms, covering the period from inception to March 26, 2025. We included only randomized controlled trials that recruited adult smokers and implemented ACT for smoking cessation, with the comparison group receiving either active treatment, no treatment, or any other intervention.
A total of 23 studies involving 8951 participants were included. The findings indicated that, compared with all types of control interventions, ACT significantly increased smoking cessation rates both immediately postintervention (RR = 1.48, 95% CI [1.03, 2.14], p = 0.04, I 2 = 81%) and at short-term follow-up (RR = 1.63, 95% CI = 1.31 to 2.01, p < 0.01, I 2 = 0%). Subgroup analyses showed that ACT significantly improved short-term cessation rates compared with behavioral support (RR = 1.60, 95% CI [1.27, 2.02], p < 0.01, I 2 = 0%), while, compared with the blank control, ACT significantly increased smoking cessation rates across three different time points (postintervention: RR = 3.11, 95% CI [2.13, 4.54], p < 0.01, I 2 = 0%; medium-term follow-up: RR = 2.55, 95% CI [1.32, 4.93], p < 0.01; long-term follow-up: RR = 3.33, 95% CI [1.66, 6.68], p < 0.01). Narrative synthesis suggested that compared with behavioral therapy, ACT may confer benefits in improving psychological outcomes, while compared with the blank control, it may also reduce daily cigarette consumption and nicotine dependence, and enhance psychological outcomes.
Acceptance and commitment therapy may be a beneficial approach for improving cessation rates, enhancing smoking cessation behaviors, and promoting psychological well-being among adult smokers. However, the quality of the included evidence was limited, thereby weakening the strength of these findings. Future rigorously designed trials with larger sample sizes, particularly those comparing ACT against other smoking cessation interventions, are warranted to further confirm its effects.

The acidic leachate injected during the mining process of ion-type rare earth ores can damage the environmental characteristics of the soil, thereby triggering the activation and release of associated heavy metals. Severe Zn contamination has been found in the environment of ion-type rare earth mining areas, but the activation and release of Zn in the soil during the leaching process have not been fully understood. This study investigated the activation and release patterns and mechanisms of Zn in soil under different leaching agents ((NH4)2SO4, MgSO4, Al2(SO4)3) and varying concentrations of Al2(SO4)3 (1%, 3%, 5%, 7%) using a simulated leaching experimental system. The results show that the activation and release patterns of Zn in the soil vary significantly under the influence of the three leaching agents. During the entire leaching cycle, the peak Zn concentration in the leachate was highest under MgSO4 leaching, while the residual Zn content in the soil under Al2(SO4)3 leaching approached the high-risk environmental threshold. The high-concentration systems (5%, 7%) of Al2(SO4)3 significantly enhanced the activation and release efficiency of Zn in the soil compared to the low-concentration systems (1%, 3%) of Al2(SO4)3. (NH4)2SO4 mainly promotes the activation and release of Zn through ion exchange between NH4+ and Zn2+ and the acidification effect; Al2(SO4)3, on the other hand, dominates the activation and release of Zn by providing a strongly acidic environment and dissolving and damaging the mineral lattice; while MgSO4 not only exchanges ions between Mg2+ and Zn2+, but also alters the soil colloidal structure, facilitating Zn activation and release. The promoting effects of the three leaching agents on the transformation of Zn in soil follow the order of Al2(SO4)3> (NH4)2SO4 > MgSO4, with the environmental risk assessment index (RAC) being highest after Al2(SO4)3 leaching, indicating the greatest potential environmental risk. Compared to the other three concentrations (1%, 5%, 7%) of Al₂(SO4)3, the 3% concentration of Al2(SO4)3 had the most significant promoting effect on the transformation of Zn in soil. This study provides a theoretical basis for optimizing the green mining process of ion-type rare earth ores and preventing heavy metal pollution, and offers scientific support for revealing pollution mechanisms and formulating remediation and risk assessment strategies.by Xiaoliang Wan, Feiyao Deng, Xue Bai, Chenxi Xiang, Chuan Xu, Linxiao Qiu
Dysregulated serum chloride levels are prevalent in critically ill patients. However, their clinical impact remains unclear. This first systematic review and meta-analysis quantified the prevalence of hypochloremia and hyperchloremia, and their associations with mortality and acute kidney injury (AKI) in critically ill populations. We searched PubMed, Embase, Web of Science, and the Cochrane Library for studies reporting hyperchloremia prevalence or outcomes in adult ICU patients until August 2025. Statistical analyses were conducted using Stata v16.0, and study quality was assessed using the Newcastle-Ottawa Scale. 34 studies (n = 175,021 patients) were included. The aggregated prevalence of hyperchloremia was 34% (95% CI [26%−43%]) and hypochloremia was 14% (95% CI [1%−28%]). Meta-analysis demonstrated that both hyperchloremia and hypochloremia were significantly associated with increased mortality, conferring a 28% (OR = 1.28, 95% CI [1.08–1.52]) and 55% (OR = 1.55%, 95% CI [1.33–1.81]) elevated risk for mortality, respectively. Crucially, a dose-response analysis revealed a non-linear relationship between serum chloride levels and mortality, confirming that the risk is independently elevated at both extremes. Furthermore, hyperchloremia was linked to an increased risk of AKI (OR = 1.40, 95% CI [1.07–1.85]). These findings establish dysregulated serum chloride as a common and clinically significant biomarker, underscoring the necessity of monitoring and managing both high and low chloride levels in critically ill patients. Future large-scale studies are warranted to validate these results and elucidate the mechanistic pathways linking chloride dysregulation to such adverse outcomes.The best evidence on programmed weaning from mechanical ventilation in neurocritical care patients should be gathered, evaluated, and integrated to provide an evidence basis for determining the optimal weaning program for these patients.
According to the ‘6S’ pyramid model of evidence-based practice resources, Chinese and international guideline websites, websites of relevant professional societies, and Chinese and English databases were systematically searched. The databases were searched from the time of establishment to October 2024. Literature screening was subsequently performed according to the inclusion and exclusion criteria. Two researchers independently evaluated the literature quality and extracted and summarised the evidence.
A total of 21 publications were included, including 3 guidelines, 5 expert consensus papers, 1 evidence summary, and 12 systematic reviews. A total of 29 pieces of best evidence in the following 5 aspects were summarised: preweaning preparation and screening, a weaning protocol, extubation assessment, extubation preparation and procedure, and postextubation management.
This study summarises the best evidence for the programmed weaning of neurocritical care patients from mechanical ventilation and provides a basis for clinical medical personnel to standardise this weaning process. Evidence-based application of these strategies should be implemented to verify their clinical efficacy and safety in practice.
Successful weaning is key in the management of neurocritical care patients receiving mechanical ventilation. The establishment of a localised extubation protocol guided by a multidisciplinary team can significantly reduce the extubation failure rate, the duration of mechanical ventilation and the incidence of related complications. However, evidence-based application is needed to verify the efficacy and safety of these strategies in clinical practice.
This evidence review adhered to the evidence review report guidelines formulated by the Evidence-Based Nursing Center of Fudan University. These guidelines cover aspects such as problem establishment, literature search, literature screening, literature evaluation, evidence summary and classification, as well as the formulation of practical suggestions. This evidence summary followed the evidence summary reporting specifications of the Fudan University Center for Evidence-Based Nursing (http://ebn.nursing.fudan.edu.cn) with registration number ES20244849.
This study was based on the evidence summary reporting specifications of the Fudan University Center for Evidence-based Nursing; the registered name is ‘Summary of the best evidence for weaning from mechanical ventilation in neurocritical care patients’; the registration number is ES20231823
To evaluate the effectiveness of the recommendation improvement matrix (RIM) methodology for improving the quality of recommendations resulting from sentinel event analysis, where we hypothesise that the use of the RIM methodology leads to better quality recommendations.
A before-and-after analysis of the quality of the formulated recommendations after sentinel event analysis.
The study was carried out during the 2023 Saudi Patient Safety Centre International Patient Safety Conference.
36 conference participants, including nurses, medical doctors, pharmacists, dentists, general practitioners and quality officers.
RIM methodology training during a structured 3-hour workshop.
The primary outcome was the proportion of recommendations that using the 2 test, passed the RIM filter criteria before and after training. Secondary outcomes included changes in recommendation categorisation within the matrix and participant ratings of feasibility and usability on a five-point Likert scale using a t-test for comparison.
Prior to training, 49 recommendations were generated, of which 63.3% met the filter criteria. Post-training, the proportion of recommendations passing the filter increased significantly to 83% (p=0.00543). Adjustments to recommendations primarily improved alignment with the filter criteria, though limited improvements were observed in matrix categorisation. Participants rated the methodology’s feasibility and usability highly, with average scores of 4.39/5 and 4.43/5, respectively. However, 46% expressed a need for additional training, particularly on the matrix application.
The RIM methodology significantly improves the quality of recommendations following sentinel event analyses. To enhance its impact, further training focusing on matrix application is necessary. Incorporating the methodology into healthcare education and professional development could strengthen patient safety practices.
This study aims to investigate whether higher levels of depression predict increased physical frailty over time and whether worsening physical frailty predicts higher levels of depression over time, at both the between-person and within-person levels.
A longitudinal study.
A total of 269 patients who underwent cardiac surgery were included in this study at T1 (admission). We followed up depression and physical frailty at T2 (the seventh day after surgery), T3 (the day before discharge), and T4 (the three-month follow-up). To determine the temporal order of the association between depression and physical frailty at both between-person or within-person levels, we employed the cross-lagged panel model (between-person effects), and random intercept cross-lagged panel model (within-person effects).
The cross-lagged panel model findings revealed a time-dependent shift in directionality: physical frailty initially predicted depression between T1 and T2, whereas depression subsequently emerged as a significant predictor of physical frailty from T2 to T4. These between-person effects suggest that the dominant direction of influence may vary across different perioperative stages. Notably, the random intercept cross-lagged panel model results identified a robust unidirectional within-person effect, indicating that increases in depression consistently predicted subsequent increases in physical frailty over time, while the reverse pathway was not statistically significant. This finding underscores the potential causal role of depression in driving physical frailty progression, beyond the influence of stable between-person characteristics.
This study advances understanding of the depression-physical frailty relationship in middle-aged and older cardiac surgery patients by delineating temporal precedence and disentangling within- and between-person effects. Depression emerges as a key driver of physical frailty, underscoring the need to prioritize its management in postoperative care protocols. Future research should explore mechanisms linking intraindividual depression to physical frailty progression and evaluate integrated psychosomatic interventions to optimize recovery outcomes.
We have adhered to the STROBE guideline.
This study did not include patient or public involvement in its design, conduct, or reporting.
Evidence-based practice (EBP) is essential for improving the quality of care and health outcomes in healthcare organizations. This study aimed to analyze the association between the nursing work environment and EBP elements, including attitude, training, implementation and quality of care.
A multicenter, cross-sectional study was conducted with 1022 registered nurses from 57 primary care centers and four public hospitals in northern Spain. The Practice Environment Scale of the Nursing Work Index (PES-NWI) was used to assess the nursing work environment. Data collection also included the Health Sciences Evidence-Based Practice (HS-EBP) questionnaire to evaluate attitudes toward EBP, and self-reported measures of EBP training, EBP implementation, and overall quality of care. Odds ratios (OR) and 95% confidence intervals for the association between the nursing work environment and EBP elements were calculated using logistic regression adjusted for sociodemographic and occupational characteristics.
Compared to nurses who reported working in unfavorable environments (n = 220; 21.5%), those working in favorable environments (n = 437; 42.8%) exhibited a positive attitude toward EBP (OR = 2.89; 95% CI [2.00, 4.18]), EBP implementation (OR = 2.30; 95% CI [1.52, 3.39]) and higher quality of care (OR = 2.35; 95% CI [1.61, 3.44]). Using a composite measure that considered all EBP elements, favorable environments were associated with overall EBP engagement (OR = 3.47; 95% CI [2.38, 5.07]). The most influential environmental dimensions were adequate staffing and strong nursing foundations.
A favorable nursing work environment was strongly associated with a positive attitude toward EBP, the implementation of EBP, and a commitment to providing high-quality care. Key strategies to promote EBP should involve healthcare and academic institutions working together to establish a healthy work environment with appropriate staffing and care foundations rooted in nursing theory.

BackgroundHypertension (HTN) progression is linked to insulin resistance (IR), yet the association between Metabolic Score for Insulin Resistance (METS-IR) and HTN remains underexplored.
MethodsThis study included 4,051 individuals without a history of HTN from the China Health and Retirement Longitudinal Study (CHARLS). Participants were stratified into four groups according to their baseline METS-IR values. It was the development of incident HTN that was the primary outcome. We used Cox regression to assess this association, conducted subgroup and sensitivity analyses, and evaluated METS-IR’s incremental predictive value over conventional risk factors (age, sex, systolic blood pressure) using C-statistic, net reclassification improvement (NRI), integrated discrimination improvement (IDI), and decision curve analysis (DCA).
ResultsOver the 9-year follow-up, 1,572 participants (38.81%) experienced their first incident of HTN. Participants were categorized into quartiles (Q1-Q4) based on their METS-IR levels. After full adjustment for confounders, the hazard ratio (HR) with a 95% confidence interval (CI) for incident HTN demonstrated a progressive increase across ascending METS-IR quartiles, with Q1 as reference: Q2, 0.99 (0.85–1.15); Q3, 1.17 (1.01–1.36); Q4, 1.31 (1.13–1.52). The restricted cubic spline (RCS) model revealed a linear dose-response relationship between METS-IR and the incidence of HTN (P for overall trend P for nonlinear = 0.310). Adding METS-IR to a base model (age/sex/systolic blood pressure) improved HTN prediction (C-statistic Δ= + 0.004; NRI = 16.58%, IDI = 0.75%; all P Conclusion
Elevated METS-IR independently predicts HTN risk in Chinese adults, suggesting METS-IR as a potential indicator.
