Acute kidney injury (AKI) is a significant challenge in hospital settings, and accurately differentiating between intrinsic and prerenal AKI is crucial for effective management. The fractional excretion of urea (FEUN) has been proposed as a potential biomarker for this purpose, offering an alternative to traditional markers such as fractional excretion of sodium. This study aimed to assess the diagnostic accuracy of FEUN for differentiating intrinsic from prerenal AKI in hospitalised patients.
We conducted a systematic review and bivariate random effects meta-analysis of diagnostic accuracy studies. The study followed the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach.
PubMed, Embase and Cochrane databases were searched from inception to 1 November 2023.
We included observational studies that focused on patient with AKI and reported FEUN data sufficient to reconstruct a complete 2x2 contingency table (true positives, true negatives, false positives and false negatives) for evaluating its diagnostic accuracy.
Two reviewers extracted data, assessed risk of bias with Quality Assessment of Diagnostic Accuracy Studies-2 and graded certainty of evidence using the GRADE approach. Pooled sensitivity, specificity, positive and negative likelihood ratios, and the area under the summary receiver operating characteristic curve (SROC) were calculated; heterogeneity was measured with I². A prespecified subgroup restricted to patients receiving diuretics served as a sensitivity analysis.
12 studies involving 1240 patients were included, with an overall occurrence rate of intrinsic AKI of 38.8%. FEUN had a pooled sensitivity of 0.74 (95% CI 0.60 to 0.84) and specificity of 0.78 (95% CI 0.66 to 0.87), with positive predictive value and negative predictive value of 0.76 (95% CI 0.68 to 0.83) and 0.74 (95% CI 0.66 to 0.81), respectively. The SROC curve showed a pooled diagnostic accuracy of 0.83. Heterogeneity was substantial (I²>90%) for sensitivity and specificity. In a diuretic-only subgroup (six studies) specificity rose to0.87 and heterogeneity declined (I²=56%). Overall certainty of evidence was low owing to inconsistency.
FEUN is a biomarker with moderate diagnostic accuracy for differentiating between intrinsic and prerenal AKI in hospitalised patients. Its application could enhance AKI management; however, the high heterogeneity observed in our study highlights the need for further research to evaluate its utility across diverse patient populations and clinical settings.

Diabetes is highly prevalent in older women worldwide. This study explores the associations of psychosocial factors with both health service utilisation and self-management in older women aged 68 to 73 years with type 2 diabetes (T2D) or pre-diabetes.
This cross-sectional study used data from the Australian Longitudinal Study on Women’s Health (ALSWH), which is a national population-based cohort study that has collected information on factors related to women’s health and well-being over 20 years.
Women aged 68–73, born between 1946 and 1951, participated in ALSWH and self-reported their diagnosis of T2D or pre-diabetes.
Resilience, dispositional optimism and perceived control were the measures of psychosocial factors. The associations between these factors and diabetes self-management behaviours, healthcare visits and preventive service use were examined by numerous regression models.
There were 939 women aged 68–73 years with T2D or pre-diabetes. Women with T2D who exhibited higher dispositional optimism had significantly higher odds of participating in moderate/vigorous physical activity (OR: 1.06), visiting a dentist (OR: 1.07) and a lower rate of general practitioner (GP) visits (rate ratio (RR): 0.99). Women with T2D with greater resilience were likely to have a lower rate of consulting with mental health professionals (RR: 0.63) and higher odds of blood sugar level checks (OR: 1.68). The rate of GP visits within a year decreased by 16% for women with pre-diabetes who had a higher resilience score (RR: 0.84), and women with pre-diabetes with greater resilience had a 13% lower rate of visits to a nurse (RR: 0.87).
Psychosocial aspects of diabetes care may be important for supporting the physical and mental well-being of older women with T2D or pre-diabetes. Healthcare providers may consider whether integrating assessments of resilience and optimism into routine diabetes management might help identify older women who could benefit from targeted psychosocial support.
This study assessed the global burden of glaucoma using data from the Global Burden of Disease (GBD) 2021 study. The analysis of epidemiological trends aimed to inform future public health prevention strategies.
Retrospective cross-sectional study.
None.
Analysis of 1990–2021 GBD data on glaucoma prevalence, disability-adjusted life years (DALYs), age-standardised prevalence rates (ASPR), and age-standardised DALY rates (ASDR). Estimated annual percentage changes (EAPC) were calculated, Joinpoint regression identified trend changes, and Autoregressive Integrated Moving Average (ARIMA) modelling projected the burden for the year 2050.
Globally, the number of prevalent glaucoma cases increased from 4 072 106.59 (95% uncertainty interval (UI) 3 489 888.7 to 4 752 867.3) in 1990 to 7 587 672.9 (95% UI 6 522 906 to 8 917 725.4) in 2021. Concurrently, DALYs increased from 467 600.4 (95% UI 323 490.5 to 648 641.6) in 1990 to 759 900.2 (95% UI 530 942.9 to 1 049 127.2) in 2021. In contrast, the ASPR and ASDR declined to 90.1 per 100 000 population (95% UI 77.8 to 105.5) and 9.1 per 100 000 population (95% UI 6.3 to 12.5) in 2021, respectively. During the COVID-19 pandemic period (2019–2021), the slowest growth rates in crude case numbers and overall disease burden were observed, accompanied by the most pronounced decline in annual percentage change of ASPR. The highest estimates for both case counts and DALYs were identified in the 70–74 age group, with males demonstrating higher prevalence rates than females. Furthermore, regions with lower Sociodemographic Index (SDI) values bore a disproportionately higher burden of glaucoma.
These findings underscore the need to strengthen early screening and treatment of glaucoma, particularly in ageing populations, male groups and low SDI regions. We urge cautious interpretation of COVID-19 related data and vigilance against potential post-pandemic surges in burden. Critical strategies include enhanced screening and intervention for high-risk groups, targeted prevention measures and integration of ophthalmic care into public health emergency frameworks to alleviate the disease burden.
Investigate the epidemiological characteristics of outpatients initially diagnosed with skin ulcers who were ultimately confirmed to have cutaneous malignant tumours, and provide a diagnostic and therapeutic basis for the occurrence of secondary diseases in chronic wounds. We conducted a retrospective study analysing clinical data from patients initially diagnosed with skin ulcers at our hospital between July 2021 and February 2025, and analysed the epidemiological characteristics of malignant transformation in these ulcer cases. Among 128 patients initially diagnosed with skin ulcers, 16 cases (12.5%) were confirmed with cutaneous malignancies. The malignant group had a significantly higher mean age (69.44 ± 11.30 years) compared to the non-malignant group (58.39 ± 17.88 years; t = 5.752, p = 0.01). The distribution of lesion sites differed significantly between the malignant and non-malignant groups (χ2 = 30.498, p < 0.01). In the malignant group, the head and neck (41.2%) and trunk & extremities (41.2%) were the predominant sites. The most common malignancy was squamous cell carcinoma (SCC). The trunk & extremities was the most frequent site (62.5%). The second was basal cell carcinoma, which mainly occurs in the head and neck (80.0%). The mean duration of ulceration was 4.5 years. The primary treatment modality was surgical excision (11 cases, 68.8%). Approximately one-seventh of skin ulcer cases were confirmed as cutaneous malignancies. This finding underscores the significance of skin ulcers as potential malignant lesions, highlighting the need for clinicians to maintain a high index of suspicion and promptly perform histopathological examinations to improve early detection rates of skin cancers.

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 develop a comprehensive decision-making checklist for paediatric advance care planning tailored to the needs of terminally ill children and their families.
A Delphi Study.
Underpinned by Delphi methodology, a four-phase procedure was adopted: (1) drafting items by the working group, (2) refining items based on an experts' survey, (3) further refining based on the same experts, and (4) final adaptations and approval. This study was initiated by the Paediatric Palliative Care Subspecialty Group of the Paediatrics Society of the Chinese Medical Association. The process involved 60 healthcare providers (physicians, nurses, and social workers) from 14 paediatric palliative care teams.
The developed checklist included 5 topics, 24 subtopics, and 45 items. Five topics were (1) medical and nursing decision-making, (2) social support planning, (3) psychological support planning, (4) spiritual support planning, and (5) posthumous affairs planning. This checklist addresses symptom management for terminally ill children, integrating support for their psychological, social, and spiritual well-being, and addresses the care needs of their family members.
The study provided a paediatric advance care planning checklist derived from the expert consensus that includes key elements and items.
This checklist provides healthcare providers with a structured framework to set paediatric advance care planning and ensure that all aspects of children's well-being and their families' needs are considered. This study also lays an evidence-based foundation for the design of related documents.
This study developed a comprehensive paediatric advance care planning checklist with 5 topics, 24 subtopics, and 45 items. This study provides a comprehensive decision-making checklist for healthcare providers and families, ensuring that critical decisions are addressed timely.

This study aims to determine the mediating effect of emotional exhaustion on the relationship between lateral violence in nursing and turnover intentions.
A cross-sectional survey.
This research project involved the enrollment of 314 nursing professionals from two tertiary medical facilities associated with academic institutions in Changsha, Hunan Province, China. To measure the variables, a series of self-administered questionnaires was used. The data were analysed using SPSS 25.
Lateral violence and emotional exhaustion were positively correlated with turnover intention. Emotional exhaustion partially mediated the relationship between lateral violence and turnover intention.
Emotional exhaustion serves as a partial mediator in the relationship between lateral violence and turnover intention. Reducing lateral violence and avoiding emotional exhaustion can help to reduce the turnover intention of nurses.
When developing targeted programs or policies aimed at decreasing nurses' turnover intention, it is important to consider the issue of lateral violence among nurses, as well as their negative emotions.
The study provides us with a more fine-grained understanding of the relationship between lateral violence among nurses and turnover intention. Insights to enhance nurse retention are also provided, which can support the development of future relevant policies and guidelines.
The study adhered to the STROBE guidelines.

To summarise peer support in digital use and digital health interventions for older adults.
The following databases were searched (from 2010 to 2024): PubMed, Embase, Web of Science, the Cochrane Library and EBSCOhost.
This review is based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. All articles selected and extracted were double-checked. The data were analysed using the inductive descriptive approach and presented in table and narrative form.
This review included 21 studies involving adults aged 60 or older, primarily from developed countries, and focused on the post-21st century. Peer support included peer digital support through face-to-face or online, peer-led or coached in digital intervention, peer motivation and companionship in digital health interventions, group-based mutual support through social media and online health platforms through websites or apps. The social cognitive theory was the common theoretical framework. Most studies indicate high feasibility, acceptability and effectiveness in six health domains. It facilitated information and behaviour exchange, improved mental health, enhanced social support, increased cost-effectiveness and adherence. However, some studies have shown ineffectiveness, influenced by peer support design issues, negative social norms, technological issues, network size and study design limitations. Besides, qualitative results indicated positive experiences enhanced personal worth and social connection, while negative experiences involved technological barriers, emotional burdens, privacy issues and lack of recognition.
Peer support represents a valuable complement to existing digital use and digital health interventions for older adults, with important implications for practices in healthcare and outcomes.
Further research should optimise peer support, maintain bi-directional relationships, explore mechanisms of influence, analyse cost-effectiveness, utilise machine-learning algorithms, apply digital peer support to more health domains and call for healthcare providers to develop relevant policies or strategies.

Percutaneous Bunnell repair and open modified Kessler repair remain debated options for acute Achilles tendon rupture (AATR). We retrospectively compared a minimally invasive percutaneous Bunnell technique (Group A) with an open modified Kessler repair (Group B) within a standardized early functional rehabilitation (EFR) protocol at a single center. Fifty-five adults with closed AATR treated between January 2021 and December 2022 were analyzed (Group A, n = 25; Group B, n = 30). Between-group comparisons used Welch t tests for continuous variables and χ² or Fisher exact tests for categorical variables; American Orthopaedic Foot & Ankle Society (AOFAS) and Achilles Tendon Total Rupture Score (ATRS) were assessed at 12 and 24 weeks, with Holm adjustment applied within each scale. Compared with Group B, Group A had shorter operative time (56.6 ± 15.1 vs 68.2 ± 23.2 minutes; mean difference −11.6; 95% CI −22.05 to −1.15; P = 0.030), less intraoperative blood loss (28.4 ± 8.4 vs 74.7 ± 19.4 mL; −46.3; 95% CI −54.22 to −38.38; PThis study aimed to identify potential categories of rotation stress among nurses undergoing standardised training and to explore the relevant factors associated with each profile.
Cross-sectional study.
Data were collected in November 2024 from three hospitals in Zunyi City, Guizhou Province, China.
Nurses undergoing standardised training were recruited for this study.
Convenience sampling method was used to recruit standardised training nurses in November 2024 from three hospitals in Zunyi City, Guizhou Province. The survey instruments used included demographic characteristics questionnaire, the Nursing Job Rotation Stress Scale and the Maslach Burnout Inventory. Latent profile analysis method was used to analyse rotation stress characteristics of nurses during standardised training. Additionally, logistic regression was performed to identify the factors influencing different characteristics.
A total of 493 nurses completed the questionnaires, of which 453 were valid, resulting in a validity rate of 91.88%. Rotation stress was classified into two profiles: ‘Low Emotional Response–Stress Adaptation Group’ (21.5%) and ‘High Emotional Response–Stress Distress Group’ (78.5%). Univariate analysis showed that highest degree (2=11.389, p=0.001), monthly night shifts (2=33.913, p2=20.858, p2=12.319, p2=35.754, p2=15.357, p=0.002) significantly influenced the two subgroups. Multivariable regression analysis revealed significant associations of monthly night shifts, pretraining work experience, training duration and burnout level (p
Nurses undergoing standardised training exhibit two distinct rotation stress profiles. Monthly night shifts, pretraining work experience, training duration and burnout are significant factors. Nursing managers should implement targeted interventions such as mindfulness, laughter therapy and emotional freedom techniques to mitigate stress and thereby enhance the quality of standardised training.
First-degree relatives of colorectal cancer (CRC) patients have a twofold to fourfold increased risk of CRC. Tailored communication interventions have shown efficacy in improving their risk awareness and screening participation. While computer-based tailoring systems offer convenience, they often overlook the integration of healthcare professionals’ verbal input, potentially limiting effectiveness and long-term impact. To address this gap, we developed ScreenTalk, an intelligent voice-interactive tailored communication system that employs intelligent speech interaction to automate the tailoring process, enhance message credibility and improve scalability within CRC screening workflows.
This study is a two-arm, cluster-randomised controlled trial with a hybrid type I design involving 314 participants across three tertiary general hospitals in Guangzhou, China. Participants in both groups will receive usual care. Additionally, the intervention group will receive a 1-month tailored intelligent voice-interactive intervention, whereas the control group will receive unrelated health education to control for attention. Screening uptake (primary outcomes) and health beliefs (secondary outcomes) are measured at baseline and at 3 months, 6 months, 9 months and 12 month post the intervention. Implementation outcomes including reach, implementation, adoption and maintenance will be assessed through questionnaire, qualitative interviews and tailored system record.
The trial has been approved by the Ethics Committee of the Sun Yat-sen University (IRB No. L2024SYSU-HL-054). Information on the purpose and process of this study will be provided to the participants before recruitment, and written signatures will be collected from all participants to ensure their voluntary participation and protection of their rights and privacy.

Ternary complex of curcuminoid-rich extract (CRE-Ter) is a developed water-soluble Curcuma longa extract containing 14% w/w curcuminoids, hydroxypropyl-β-cyclodextrin, and polyvinylpyrrolidone K30. This study aimed to investigate the biomolecular effects of CRE-Ter on differentiation of bone cells (murine MC3T3-E1 preosteoblasts), muscle cells (murine dexamethasone-treated C2C12 myotubes) atrophy and irisin expression. In MC3T3-E1 preosteoblasts, CRE-Ter treatment increased alkaline phosphatase activity, calcium deposition, and expression of Bmp-2, Runx2, and collagen 1a significantly and dose-dependently. 5, 10, and 20 µg/mL CRE-Ter upregulated β-catenin expression significantly. CRE-Ter improved the atrophy of dexamethasone-treated C2C12 myotubes. CRE-Ter decreased proinflammatory cytokine (TNF-α and IL-6) expression but increased FNDC5 and irisin expression and nitric oxide production in dexamethasone-treated C2C12 myotubes significantly and dose-dependently. Dexamethasone promoted β-catenin and total p38 expression in C2C12 myotubes. CRE-Ter at 2.5–20 µg/mL reversed the increase in β-catenin expression, whereas 2.5 µg/mL reversed total p38 expression. Crosstalk experiments further revealed that conditioned medium from C2C12 myotubes enhanced osteocalcin expression in MC3T3-E1 osteoblasts. Molecular docking simulations using CB-Dock2 showed strong interactions between each curcuminoid molecule and irisin. Therefore, CRE-Ter may stimulate osteoblast differentiation, ameliorate myotube atrophy, and increase irisin expression, indicating its therapeutic potential in osteoporosis, sarcopenia, and osteosarcopenia.by Bing Wu, Pengli Wei, Jiaxiang Deng, Yuanyuan Rui
BackgroundThe atherogenic index of plasma (AIP) is a recognized marker of atherosclerosis and cardiovascular disease (CVD). However, the association between AIP and the risk of acute kidney injury (AKI) in critically ill patients with sepsis has not yet been investigated.
MethodsThe data used in this study were derived from the Medical Information Mart for Intensive Care (MIMIC-IV) database. The clinical outcome was the occurrence of AKI. Logistic regression was used to assess the association between AIP and the risk of AKI in sepsis patients. Restricted cubic spline (RCS) analysis was applied to explore potential non-linear relationships. Threshold analysis confirmed a turning point at this value. Subgroup analyses evaluated the consistency of the association across different strata. Mediation analysis was performed to explore potential intermediate variables.
ResultsAmong 1,874 sepsis patients, higher AIP levels were associated with increased AKI incidence. Logistic regression showed a significant association between AIP and AKI in unadjusted and partially adjusted models, but the association was no longer significant after full adjustment. RCS analysis revealed a nonlinear relationship with a peak AKI risk at AIP = 1.333. Threshold analysis confirmed a turning point at this value. Subgroup analyses showed consistent associations, while nonlinear effects were more evident in specific groups. Mediation analysis suggested that SOFA score, creatinine, WBC count, and respiratory rate partially mediated the AIP-AKI relationship.
ConclusionAIP was nonlinearly associated with AKI in sepsis, with a clear threshold effect. This relationship was partially mediated by SOFA score, creatinine, WBC, and respiratory rate. AIP may serve as a useful marker for AKI risk assessment.
Coronary artery involvement remains the primary focus in the long-term management of Kawasaki disease (KD). However, previous studies suggest that myocardial abnormalities frequently persist beyond coronary artery involvement in KD patients. Yet, their temporal evolution and clinical implications remain poorly characterised. To address this gap, we established the Kawasaki disease cardiac imaging (KDCI) cohort, integrating cardiac magnetic resonance (CMR) with echocardiography, coronary CT angiography (CCTA) and invasive angiography. These multimodal imaging approaches enable comprehensive assessment of cardiac abnormalities and elucidate the role of cardiac imaging in optimising long-term KD management.
The KDCI cohort is a prospective study aiming to enrol 400–500 KD patients diagnosed at West China Second University Hospital from September 2018 to September 2035. To date, 207 participants have been recruited. Participants will perform the multimodal cardiac imaging including echocardiography, CMR, CCTA, invasive angiography and comprehensive laboratory testing under a scheduled protocol in the follow-up.
The KDCI cohort has established baseline characteristics for 207 KD patients. Of those included to date, 72.0% (149/207) received intravenous immunoglobulin (IVIG) treatment, with 26.1% (54/207) demonstrating IVIG resistance, and 37.7% (78/207) exhibiting coronary artery dilatation. Longitudinal follow-up data are available for 80.7% (167/207) of participants, with a median follow-up duration of 2.7 years and a follow-up patient-years of 594 patient-years. Of the 207 patients, 16.9% (35/207) patients experienced endpoint events, encompassing coronary artery thrombosis (8.2%, 17/207), coronary stenosis/obstruction (5.3% 11/207) and clinical myocardial infarction (1.9%, 4/207). Based on the data collected, we have demonstrated the cardiac abnormalities beyond coronary artery involvement in KD by CMR and CCTA.
The KDCI cohort will maintain ongoing recruitment and longitudinal follow-up, with a projected enrolment exceeding 400 participants by 2035. This expansion will yield a median follow-up duration of 10 years, providing robust long-term outcome data. We have implemented standardised protocols for scheduled follow-up assessments and data collection in newly enrolled patients. Furthermore, planned genomic analyses will be incorporated to investigate the molecular pathogenesis and prognostic determinants of KD.
Physical activity (PA) has considerable benefits for older adults, yet they often face various barriers that hinder participation. Peer-led or peer-supported PA interventions represent a promising strategy to address barriers, such as cost and lack of motivation. Although existing reviews suggest that these interventions improve PA adherence, combining randomised controlled trials (RCTs) with other study designs may weaken their validity. Furthermore, their effects on PA levels and physical function are inconsistent, and their impacts on cognitive abilities, psychosocial well-being and social support, as well as the influence of peer characteristics and programme design, remain unexamined. This review aims to synthesise evidence regarding the effectiveness of peer-led or peer-supported PA interventions across multiple health outcomes and identify possible influencing factors.
The search will encompass six English and three Chinese databases, namely, PubMed, Web of Science, Embase, Cumulative Index to Nursing and Allied Literature, PsycINFO, CENTRAL, China National Knowledge Infrastructure, Wanfang Data and the Chinese Biomedical Literature Database. It will cover literature from inception to December 2025. Trial registries will be searched, and a manual search of relevant studies will also be conducted. RCTs that focus on community-dwelling older adults participating in peer-led or peer-supported PA interventions will be included. Outcomes include PA levels, physical function, cognitive function, psychosocial well-being, self-efficacy, social support, health-related quality of life (HRQoL) and programme adherence. Two reviewers will independently screen the literature, extract data and evaluate the risk of bias by using the Cochrane Risk of Bias Tool 2.0. Meta-analyses will be conducted for outcomes reported in at least two studies, and narrative analyses will be performed for others. Subgroup analyses, metaregression, sensitivity analyses and assessments of publication bias will be conducted as appropriate. The Grading of Recommendations, Assessment, Development and Evaluations approach will be used to assess the certainty of evidence.
Ethical approval is not required because only published data will be used. Results will be disseminated through peer-reviewed publications and conference presentations.

BackgroundAlthough metformin is the first-line medicine for type 2 diabetes (T2D), its safety profile in adolescents remains poorly understood. This study seeks to investigate the adverse events linked to metformin use in adolescents diagnosed with T2D.
MethodsData from the Food and Drug Administration Adverse Event Reporting System (FAERS), spanning Q1 2004 to Q2 2024, were retrospectively analyzed in this study. Adverse reactions were standardized using the Medical Dictionary for Regulatory Activities, then significant adverse drug reaction signals were identified through disproportionality analysis employing reporting odds ratio (ROR) and information component (IC) methods.
ResultsOf 17,956,653 FAERS reports, 80,187 involved metformin, including 973 in adolescents (10–19 years), with 174 cases were identified with a T2D indication. Analysis at the system organ class level revealed that congenital, familial, and genetic disorders [ROR: 8.8 (4.0, 19.3); IC: 2.2 (1.1, 2.9)] and pregnancy conditions [ROR: 4.9 (2.5, 9.5); IC: 1.8 (0.8, 2.5)] showed the most significant signals. At the preferred term (PT) level, three signals were identified across all sexes and subgroups: treatment noncompliance [ROR: overall 4.14 (2.44, 7.02), male 4.27 (2.00, 9.12), and female 4.65 (2.22, 9.74); IC: overall 1.67 (0.88, 2.22), male 1.60 (0.46, 2.36), and female 1.74 (0.60, 2.50)], lactic acidosis [IC: overall 2.99 (1.91, 3.72), male 2.53 (0.76, 3.61), and female 2.76 (1.34, 3.67)], and gastrointestinal disorder [ROR: overall 13.09 (4.73, 36.23), male 54.33 (6.05, 487.96), female 5.34 (1.10, 25.84)]. Neurological disorders were observed only in males, while pregnancy-related adverse effects and renal disorders occurred exclusively in females. Additionally, the study identified potential new signals not documented in metformin labeling, including areflexia, muscle weakness, ataxia, decreased vibratory sense, rhabdomyolysis, substance use, and axillary pain.
ConclusionThe study reveals a complex safety profile of metformin in adolescents with T2D, warranting further research to confirm risks.
Post-induction hypotension (PIH) is a critical concern in elderly surgical patients and is associated with adverse postoperative outcomes. This trial aims to compare the effects of propofol, etomidate and remimazolam on the incidence of PIH in older adults undergoing non-cardiac surgery.
In this single-centre, triple-arm, randomised controlled trial, 210 patients aged ≥80 years with American Society of Anaesthesiologists physical status I–III undergoing elective non-cardiac surgery will be recruited. All patients will receive general anaesthesia with endotracheal intubation. Patients will be randomised (1:1:1) to receive propofol, remimazolam or etomidate for anaesthesia induction (n=70 per group). The primary outcome is the incidence of PIH (mean arterial pressure (MAP) 30% from baseline, vasopressor requirements, bradycardia, injection pain, myoclonus, postoperative delirium, and cardiac, cerebral and renal complications during hospitalisation.
This trial was approved by the Ethics Committee of the First Affiliated Hospital of Soochow University (Approval No. 2024-380). The results will be peer-reviewed for publication in a scientific journal.

BackgroundMyocardial infarction (MI) and cancer are major global public health challenges. Research indicates that they share common risk factors and that physiological changes following MI may affect cancer incidence and progression. However, evidence defining the independent relationship between these conditions is still limited.
MethodsWe analyzed data from the National Health and Nutrition Examination Survey (NHANES) (2011–2018) using multivariable weighted logistic regression to examine the association between myocardial infarction (MI) and cancer. Additionally, we utilized genome-wide association study (GWAS) summary statistics and conducted Mendelian randomization (MR) to assess potential causal relationships and explore underlying mechanisms. Sensitivity analyses were performed to ensure the robustness of our findings.
ResultsA total of 20,859 participants were included in our observational study using NHANES data. Multivariable weighted logistic regression revealed no direct association between MI and cancer (OR=1.161, 95% CI [0.895–1.507], P = 0.261). Interestingly, MR analysis indicated that MI occurrence was associated with a reduced incidence of cancer (OR=0.9497, 95% CI [0.9223–0.9778], P = 0.0005). Furthermore, two-stage MR results suggested this reduction might be mediated by increased blood levels of metabolites that inhibit cancer development, such as dihomo-linoleate (20:2n6) (beta = −0.0050, 95% CI [−0.0027–0.0004], P Conclusion
Our integrative analysis suggests that myocardial infarction may be associated with a reduced cancer incidence through potential alterations in blood metabolite profiles, including dihomo-γ-linolenic acid, alpha-tocopherol, and inosine. These findings provide preliminary evidence that warrants further large-scale studies to validate the observed associations and to elucidate the underlying mechanisms.
