BackgroundDiabetic peripheral neuropathy (DPN) is a common complication of type 2 diabetes mellitus (T2DM) and is closely linked to immune and inflammatory dysregulation. Multi-component pharmacological interventions have been explored as complementary approaches for metabolic and immune modulation; however, their effects on DPN and related mechanisms remain incompletely understood.
MethodsA rat model of T2DM-associated peripheral neuropathy was established, and a multi-component pharmacological intervention (MPCI) was administered for 8 weeks. Peripheral nerve dysfunction was evaluated by motor and sensory nerve conduction velocities (MNCV and SNCV), behavioral outcomes, and histological/ultrastructural assessments. In parallel, spleen tissues were collected for transcriptomic profiling. RNA sequencing was performed to identify differentially expressed genes and immune-related pathways, and representative molecules involved in inflammatory regulation were further validated using western blotting and quantitative real-time PCR in sciatic nerve tissue.
ResultsMPCI administration significantly ameliorated peripheral nerve dysfunction in T2DM rats, as evidenced by improved nerve conduction velocities and pathological features. Transcriptomic analysis of spleen tissue revealed that MPCI was associated with broad remodeling of diabetes-related immune and inflammatory gene programs. In parallel, sciatic nerve analyses showed attenuation of NF-κB/c-Jun–associated inflammatory signaling and modulation of inhibitory regulators at both the protein and mRNA levels.
ConclusionThese findings indicate that MPCI improves T2DM-associated DPN and is associated with splenic immune remodeling and attenuation of peripheral nerve inflammatory signaling, providing exploratory evidence for associations between splenic immune transcriptomic remodeling and peripheral nerve inflammatory signaling.
To assess caregiver burden and its relationship with health literacy, self-efficacy, stigma, and social support among caregivers of children with tuberculosis in Shanghai, China.
Explanatory sequential mixed-methods design.
In the quantitative phase, 132 caregivers were recruited from a Shanghai Hospital, and 21 participated in the qualitative interviews. Data were collected (April 2023–April 2025) using the Zarit Burden Interview scale, Chinese Health Literacy Scale for Tuberculosis, General Self-Efficacy Scale, Tuberculosis-related Stigma Scale, Multidimensional Scale of Perceived Social Support, and semi-structured interviews. Quantitative data were analysed using descriptive statistics and multiple regression analyses, and qualitative data were analysed using content analysis.
Most caregivers were mothers (72.7%). Burden levels were classified as mild (58.3%), moderate (27.3%), or severe (2.3%). The quantitative analysis identified lower health literacy, limited social support, reduced self-efficacy, and being a female caregiver as significant predictors. Social support partially mediated and self-efficacy mediated the effect of perceived stigma and health literacy on caregiver burden, respectively. Qualitative themes revealed psychological and physical effects, impact on social life, and coping strategies.
Caregiver burden in paediatric tuberculosis is multidimensional and influenced by complex mechanisms. Interventions should address health literacy gaps, enhance self-efficacy, strengthen social support systems, and implement targeted stigma-reduction strategies while considering developmental-stage-specific needs.
Healthcare systems should routinely assess caregiver burden, and multidisciplinary teams should be trained to provide integrated targeted support.
This study demonstrates distinct stigma pathways and comprehensively shows that caregiver burden is significantly associated with modifiable psychosocial factors. Consequently, healthcare providers should develop targeted support interventions that address both psychological and practical caregiving challenges, ultimately contributing to improved patient care outcomes and caregiver well-being in tuberculosis management.

BackgroundResidual mother-to-child transmission (MTCT) of hepatitis B virus (HBV) remains a significant clinical challenge despite standard immunoprophylaxis. Identifying molecular markers is crucial for improved prevention and diagnosis.
MethodsWe conducted a case-control study using the Guangxi Liuzhou HBV MTCT registry. Peripheral blood RNA sequencing (Illumina HiSeq) was performed on infants from HBsAg-positive mothers: cases (HBsAg-positive, n = 6) and controls (HBsAg-negative, n = 10). All infants receive HBIG and the first dose of hepatitis B vaccine within 24 hours after birth, followed by completion of the three-dose vaccination series. Differentially expressed miRNAs (DEMs; adj-p 1) were identified. Target genes were predicted (miRanda/RNAhybrid) and functionally analyzed (GO/KEGG enrichment, PPI network). HBV-associated target genes were identified by cross-referencing GeneCards/NCBI.
ResultsRNA-seq identified 62 DEMs (19 upregulated, 43 downregulated). Target prediction yielded 5,014 genes. Functional enrichment highlighted key pathways and processes. PPI analysis pinpointed highly connected genes. Integration with HBV databases revealed 3 key target genes potentially modulated by 4 specific DEMs (hsa-miR-6747-3p, hsa-miR-4772-3p upregulated; hsa-miR-4676-5p, hsa-miR-485-5p downregulated).
ConclusionThis study identifies dysregulation of 4 key miRNAs and their association with 3 HBV-linked target genes as potential contributors to residual HBV MTCT. These findings provide novel insights into the molecular mechanisms underlying HBV MTCT and suggest potential targets for intervention.

The purpose of this study was to examine whether short-duration phase-change material cooling (PCM) applied at different temperatures influences acute recovery following fatigue induced by stretch–shortening cycle exercise (SSC). Sixty-four physically active participants were randomly assigned to 5°C, 10°C, or 15°C PCM cryotherapy group or a passive recovery control group. After completing a SSC fatigue protocol, participants underwent a 15-minute PCM intervention, and peak torque (PT), mean power, rate of force development (RFD), countermovement jump (CMJ) performance, Rating of perceived exertion (RPE), modified endurance ratio (MER), vastus lateralis (VL) and Rectus Femoris (RF) stiffness were assessed immediately after fatigue (Imm-fatigue), immediately after PCM cryotherapy (Imm-PCM), and 60 minutes post PCM cryotherapy (Post60-PCM). Mean power and RFD were significantly greater in PCM groups compared with the control group at Imm-PCM (P ≤ 0.01), with mean power remaining elevated in the 15°C PCM group at post-60-PCM (P ≤ 0.05). RPE was significantly lower in all PCM groups at Imm-PCM and post60-PCM compared with control (P ≤ 0.01). No between-group differences were observed for PT, CMJ, MER, or muscle stiffness, and no temperature-dependent effects were detected within the 5–15 °C. These findings indicate that 15-minute PCM cryotherapy selectively accelerates early-phase neuromuscular and perceptual recovery without affecting maximal strength, endurance capacity, or passive muscle mechanical properties. From an applied perspective, PCM cryotherapy may be an effective strategy to enhance explosive performance and perceived readiness during short recovery intervals in training or competition settings.To explore emergency nurses' experiences and perceptions of violence from patients and visitors in China, focusing on its nature, contributing factors, and consequences.
A qualitative descriptive design was employed.
Thirteen emergency nurses from eight tertiary public hospitals in a provincial capital city in northern China were recruited using purposive and snowball sampling; most were female and had several years of emergency nursing experience. Data were collected through semi-structured, face-to-face interviews conducted in Mandarin and analysed using latent content analysis.
Two overarching themes were identified. The first theme, Nurses as Healers or Targets: Confronting Misplaced Anger, described how violence from patients and visitors emerged in high-pressure emergency environments, often involving verbal abuse, threats, or physical aggression, and was shaped by situational stressors and perceived power imbalances. The second theme, Healing in Shackles: Maintaining Professional Composure and Emotional Desensitization, captured nurses' efforts to remain professional while experiencing fear, exhaustion, and emotional distancing following repeated exposure to violence.
Violence from patients and visitors represents a persistent occupational challenge for emergency nurses, with cumulative effects on their emotional wellbeing and professional functioning. The findings highlight the need to shift responsibility for managing violence from individual nurses to organizational and systemic levels.
Strengthening organizational responses, such as emotional support mechanisms, clear visitor management policies, and accountability for violence prevention, may help create safer and more sustainable emergency care environments.
This study adhered to the COREQ reporting guidelines.
1. What problem did the study address? This study addressed the persistent problem of violence against emergency nurses in urban tertiary hospital emergency departments in northern China, particularly incidents perpetrated by patients and visitors. It explored how nurses perceive the nature of such violence, the factors contributing to its occurrence, and its consequences for their professional and personal well-being.
2. What were the main findings? Violence against nurses by patients and visitors in the ED was often driven by enabling factors, such as high-pressure environments, nurses' visibility, and perceived power imbalances, as well as by reward-based motivations. Nurses responded with professional composure but reported limited peer and managerial support. Over time, cumulative exposure led to physical harm, lingering emotional distress, heightened vigilance, and emotional detachment.
3. Where and on whom will the research have an impact? The findings will inform nurse leaders, policymakers, and hospital administrators by reframing resilience as an organizational responsibility. Embedding structured emotional support, transparent visitor management, and violence-prevention accountability within hospital governance can foster safer and more sustainable work environments.

To synthesise evidence from qualitative studies on community-dwelling older adults' experiences of social interactions in group interaction programmes.
A systematic review and meta-synthesis based on the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines.
Two independent researchers screened the titles and abstracts of all retrieved studies based on eligibility criteria. Quality appraisal was conducted based on the comprehensive Critical Appraisal Skills Programme checklist. Data were extracted through an adapted Data Extraction Tool from the Joanna Briggs Institute Qualitative Assessment and Instrument. Findings were synthesised through the JBI meta-aggregation approach.
A literature search for peer-reviewed studies was conducted across seven databases from inception to September 2023.
Our review included the experiences of 395 community-dwelling older adults across 25 studies, yielding the overarching theme of ‘Navigating relationships and facilitating growth in a supportive community’. Five themes were identified: feeling safe in a familiar environment, bringing people together, establishing meaningful relationships, improving personal well-being and facing socialising challenges.
Our findings provided not just theoretical insights but also practical implications. They can serve as a solid foundation for formulating or enhancing similar programmes, directly addressing the pervasive issues of loneliness and social isolation among the ageing population worldwide.
This review improves our understanding of the social, emotional and personal benefits for older adults upon engaging in group interaction programmes. The insights into the elements of successful group interaction programmes for older adults, include providing a safe and familiar setting and bringing people together for socialisation. Future interventions should incorporate these elements to promote social interactions and community engagement more effectively to mitigate loneliness among older adults. Finally, the diverse range of programmes explored in this review demonstrates that future programmes can be flexibly formulated to suit different interests.

Digital Creative Art Interventions (DCAIs) are innovative approaches to art interventions using digital technology, which can improve older adults' health. However, a comprehensive summary of the implementation of this intervention among older adults is lacking.
To summarise the deliveries and categories of DCAIs, review their feasibility and roles in older adults' healthcare, and explore the barriers and facilitators to implementing DCAIs in older adults.
Scoping review.
This scoping review followed Arksey and O'Malley's framework, and PRISMA-ScR was used to guide the report.
PubMed, Embase, EBSCOhost, Web of Science and Cochrane Library on 26 February 2024.
Thirty-one studies were selected in this review. We summarised the deliveries and categories of DCAIs in older adults. Besides, we cleared DCAIs to offer music, dance, museum, photo collage, drama, visual art interaction and mixed art intervention to older adults, primarily through videoconferencing or mobile applications. The five health promotion roles were physiological health enhancer, psychological caregiver, socialisation supporter, cognitive promoter and life optimiser. Most older adults believed DCAIs were not only feasible and acceptable, but they also met some barriers such as technological problems, problems brought about by older adults' decline in functioning, experience and privacy.
Despite the unique advantages of DCAIs, continuous improvements are needed. In the future, researchers and healthcare workers should focus on platform improvements, increasing interactivity, diversifying formats and ensuring security and privacy.
This review found that DCAIs offered new approaches to treatment options for older adults' physical and mental health. Therefore, it is recommended that they be continuously optimised and put into clinical practice.
No patient or public contribution.
This study summarised the DCAIs and provides the new approach for health promotion in older adults.

Virtual reality-reminiscence therapy (VR-RT) has increasingly been applied to older adults to improve psychological well-being and cognition.
This review aims to identify (1) the design characteristics of conducting a VR-RT and (2) the effects of VR-RT on the user experience, cognitive outcomes and psychological well-being.
Systematic review.
Eligible studies were sourced across nine electronic databases, trial registries, grey literature and hand-searching of the reference list. A narrative synthesis was conducted. Twenty-two studies were included, and most were appraised as high quality. Most of the VR-RTs were highly immersive and personalised, with participants having the autonomy of control. VR-RT has the potential to improve anxiety and depression, and cognitive outcomes for older adults. Overall, VR-RT was reported to be an enjoyable experience for older adults.
VR-RT is a promising innovation that can improve older adults' psychological well-being and cognition without significant side effects, including cybersickness and with the potential for scalability across various settings. More randomised controlled studies are needed to evaluate the effectiveness of VR-RT and its features and treatment dosage. These studies could also examine the effectiveness of VR-RT as an intervention to promote independence in activities of daily living and physical rehabilitation.
VR-RT is a promising intervention for older adults in community settings to enhance psychological well-being and cognition. VR's versatility enables personalised experiences within dynamic virtual environments, possibly enhancing engagement and therapeutic outcomes.

Chronic wounds, including Diabetic Foot Ulcers (DFUs), Venous Leg Ulcers (VLUs) and Pressure Ulcers (PUs), present significant challenges for the patients, clinicians and healthcare systems. There remains a strong need for novel and effective technologies to accelerate the healing of these wounds. The objective of this prospective, single-arm pilot study was to evaluate the clinical performance of a novel nanofiber wound matrix for the treatment of chronic lower extremity wounds refractory to standard-of-care treatment at a single centre. A total of 15 patients with 15 chronic wounds (5 DFUs, 8 VLUs and 2 PUs) were included in this study. These wounds were non-healing to previous standard-of-care treatments for an average of 4 weeks. They were all treated with the novel nanofiber wound matrix with weekly clinical evaluation and re-application for a total duration of four (4) weeks, per the study protocol. The average wound area reduction (WAR) was 83.6% upon 4 weeks of treatment with the application of the subject wound matrix, as an adjunctive measure to the standard of care. Additionally, seven (7) of the 15 wounds (46.7%) completely healed starting from Week 3, and the average complete healing time was 13.9 days. These results demonstrated accelerated healing effects of the subject wound matrix, when compared to the standard of care reported in literature, where the average WAR was at 62.9% at Week 12, six (6) of the 18 wounds (33.3%) were completely healed within 12 weeks, and the average complete healing time was 49.0 days. These results demonstrated that the subject wound matrix is a safe and effective novel technology in treating chronic wounds, providing significant clinical and economic benefits for patients with various chronic wounds.

Multimorbidity, the presence of multiple chronic health conditions, is a leading cause of death globally. In Malawi, chronic noncommunicable and communicable diseases such as HIV frequently co-exist, putting pressure on an under-resourced system. However, the health system is primarily structured around disease-specific [vertical] programs, which hinders person-centred care approaches to multimorbidity. Our study focuses on multimorbidity care and explores the perceptions of healthcare workers on the patient pathways and service organisation throughout the patient’s interaction with the health facilities. This cross-sectional qualitative study took an interpretivist approach. We conducted 13 days of clinical observations at Queen Elizabeth Central Hospital and Chiradzulu District Hospital. We also conducted 13 days of clinical observations and semi-structured in-depth interviews with different cadres of purposively sampled healthcare workers (n = 22) at Queen Elizabeth Central Hospital and Chiradzulu District Hospital. Through thematic analysis, we identified an understanding of the organisation of care and healthcare workers’ perspectives on the delivery of services. Findings showed both hospitals provided services for inpatients and outpatients with multimorbidity, including screening, management, prevention of secondary conditions and rehabilitation. Patient diagnosis and management for multimorbidity were often delayed due to frequent stockouts of medication and consumables necessary for diagnostic testing for NCDs at the hospital level. Some healthcare workers were not equipped with the knowledge, skills, or guidelines to manage multimorbidity. As HIV care is currently better resourced than other chronic conditions, healthcare facilities may strengthen the supply chain, healthcare workers’ training sessions and monitoring and evaluation tools to ensure NCDs are well managed, learning from HIV programmes.by Metha Yaikwawong, Khanittha Kamdee, Kasarnchon Mek-yong, Somlak Chuengsamarn
This work aimed to clarify how polymorphisms in the TNF gene relate to metabolic syndrome (MetS), type 2 diabetes mellitus (T2DM), and a broad spectrum of cardiometabolic characteristics, while also determining their impact on circulating TNF‑α concentrations. A total of 765 participants were genotyped for rs1800629 and rs361525, and serum TNF-α was also measured. To assess these relationships, multivariable logistic regression models—incorporating age, sex, and body mass index (BMI)—were applied to estimate adjusted odds ratios (aORs) and their corresponding 95% confidence intervals (CIs). Both variants were significantly associated with MetS: rs1800629 (crude OR = 2.22, 95% CI: 1.45–3.44, P P P = 0.035; adjusted OR = 2.84, 95% CI: 1.17–7.31, P = 0.025). The rs1800629 variant was also linked to T2DM risk (adjusted OR = 2.61, 95% CI: 1.35–5.24, P = 0.006), whereas rs361525 showed no such association. Carriers of rs1800629 had higher mean TNF-α levels (PHyperbaric oxygen therapy (HBOT) enhances wound healing by promoting angiogenesis and reducing hypoxia. However, the role of air-breaks—intermittent exposures to ambient air during HBOT—remains unclear. We investigated the effects of air-breaks on HBOT-mediated wound healing, particularly in combination with adipose-derived stromal cells (ASCs). Full-thickness wounds were created in C57BL/6 mice (n = 36) and assigned to control, HBOT (1 h/day, 2 ATA for 11 days), or HBOT with a 10-min air-break groups. In a second experiment, we evaluated ASC treatment combined with HBOT and air-breaks. Wound healing was assessed via gross examination, histology and gene expression analysis of collagen type 1 alpha 1 (Col1a1), hypoxia-inducible factor 1 alpha (Hif1a) and tumour necrosis factor (Tnf-α). Compared with HBOT alone, air-breaks significantly improved wound closure, epithelial regeneration and collagen deposition (p < 0.05). Gene analysis showed higher Col1a1 expression and lower Hif1a and Tnf-α levels in the air-break group. In ASC-treated wounds, air-breaks further accelerated healing, enhancing collagen synthesis and reducing hypoxia and inflammation. These findings suggest that incorporating air-breaks into HBOT protocols improves wound healing outcomes, both generally and in ASC-based therapies, by modulating collagen production, hypoxia and inflammation, and could optimise HBOT efficacy, particularly in cell-based regenerative therapies.

Epilepsy is a prevalent neurological condition that impacts a significant number of individuals worldwide. Patients’ physical and mental health, as well as their daily activities, are significantly affected by seizures, necessitating prompt diagnosis and treatment. The automatic detection of epilepsy using electroencephalogram (EEG) signals has been a significant area of research. Nevertheless, the majority of current methods are based on intricate feature engineering processes that require the extraction and selection of a large number of features to identify the most discriminative feature sets. This results in a high level of algorithmic complexity, inadequate robustness, and inadequate interpretability, which complicates the provision of theoretical support to clinicians. This paper proposes a pathophysiology-driven, interpretable machine learning algorithm to address the limitations of current EEG-based epilepsy detection methods, which include poor interpretability and complex feature engineering. We developed a low-dimensional, interpretable feature combination consisting of only five features and systematically validated its discriminative capability across various epilepsy phases by innovatively integrating electrophysiological markers of epileptic seizures with nonlinear dynamical properties. In the binary classification of seizure versus non-seizure EEG segments, the XGB classifier achieved the highest accuracy of 98.73% and an F1 score of 98.57%. Classification accuracy for interictal versus ictal periods reached 95.33%, with an F1 score of 95.27%. In the challenging ternary classification task encompassing preictal, interictal, and ictal periods, the model achieved a respectable accuracy of 86.3% and an F1 score of 85.79%. Cross-database validation yielded a maximum accuracy of 82.17% and an F1 score of 81.99%, confirming the proposed features’ robust generalization capability and transformative potential. This feature set exhibits outstanding and stable performance across all models, as demonstrated by evaluations across two public datasets using five machine learning classifiers. In addition, SHAP values quantified the contribution of each feature to predictions, thereby providing a transparent decision-making rationale that substantially improves the algorithm’s interpretability and clinical utility.Mortal distress encompasses emotional, cognitive, physical and behavioural responses to death and dying among healthcare staff who frequently encounter mortality in hospital settings. Healthcare workers often experience heightened levels of mortal distress due to their regular exposure to patient deaths, which can negatively impact both their personal and professional lives, leading to burnout and high turnover rates.
To identify and quantitatively synthesise correlates of mortal distress among hospital healthcare staff and examine moderating factors affecting these relationships.
Systematic review and meta-analysis following PRISMA 2020 guidelines
Two independent reviewers screened and extracted data from studies published between January 1990 and December 2024 across eight databases (five English: CINAHL, MEDLINE, ProQuest, PubMed, Scopus; three Chinese: Airiti, CNKI, Wanfang). Quality assessment was conducted using the Mixed Methods Appraisal Tool. Meta-analysis was performed using Comprehensive Meta-Analysis 3.0.
Analysis of 94 studies identified three factor domains: personal, job-related and situational. Four job-related factors demonstrated the strongest correlations with mortal distress: competence in coping with death in healthcare contexts, needs for death-related or hospice care training, quality of end-of-life communication, and working in departments with high patient mortality rates. Four significant moderators influenced correlation strength: publication language, geographic region, study quality, and measurement tools used for assessing mortal distress.
This synthesis provides evidence regarding the magnitude and strength of factors associated with mortal distress among healthcare staff. The identification of main and moderator effects emphasises the critical need for developing culturally sensitive, tailored interventions to help healthcare workers navigate mortality-related challenges.
The results can guide healthcare organisations in developing targeted interventions and training programs, inform medical and nursing education curricula by encouraging the inclusion of life and death education, and ultimately enhance staff well-being while improving the quality of patient and family care, especially in palliative care contexts.

Understanding the patient perspective is crucial for enhancing healthcare delivery and outcomes for chronic conditions like diabetic foot ulcers. This qualitative study examined the perspectives of patients with diabetic foot ulcers to inform clinical strategies for both physicians and current patients to enhance care and prevent lower extremity amputations. Fifteen patients with a history of diabetes and diabetic foot ulcers and/or amputations participated in semi-structured interviews which explored their lived experiences and advice for both physicians and fellow patients to improve diabetic foot ulcer related care. Interview transcriptions were analysed to identify recurring themes. Advice for physicians emphasised increasing patient education, initiating preventive foot care at the time of diabetes diagnosis, providing instructions for managing diabetic ulcers early and demonstrating empathetic bedside manner. Advice for fellow patients focused on adopting healthy lifestyle practices, regular foot self-examinations, consistent blood glucose monitoring, medication adherence and seeking prompt medical attention for new or worsening foot lesions. Participants also stressed the importance of routine check-ups with providers to support prevention and management efforts. This qualitative study highlights the value of incorporating patient perspectives to improve our understanding of diabetic foot ulcer onset, care and outcomes and thereby reduce the risk of lower extremity complications.

To enhance the efficiency, safety, and data accuracy of drilling engineering, this study developed an integrated business management platform for drilling engineering grassroots units based on the Business Model Driven (BMD) approach. The platform is built on a “five horizontal, three vertical” cloud computing architecture, establishing a five-layer system from the infrastructure layer to the user layer horizontally, and supported by standard specifications, safety, and maintenance systems vertically, enabling collaboration across multiple business scenarios and data integration. Currently, four major modules with over 20 functionalities have been developed, supporting applications such as task coordination, engineering supervision, data analysis, and accident handling. Operational results demonstrate that the platform effectively promotes integrated management of drilling engineering through real-time data sharing, full-process quality control, and intelligent decision-making, thereby enhancing operational quality and safety, reducing accident risks, and providing critical technological support for the digital transformation and upgrading of the drilling industry.At-risk mothers experience disproportionately higher rates of antenatal depression and anxiety, which can hinder mother–infant bonding and adversely affect infant socioemotional development. Despite growing evidence on postpartum mental health, antenatal risk factors among psychosocially vulnerable mothers remain underexplored, particularly in multi-ethnic Asian settings.
To identify factors associated with antenatal depression, anxiety, and maternal–fetal bonding among at-risk mothers.
This cross-sectional observational study was nested within an ongoing randomised controlled trial. Two hundred at-risk mothers, defined as single, of low socioeconomic status, referred for psychosocial support, at risk of depression, with adverse childhood experiences, or with a fetus with a congenital malformation, were recruited from outpatient obstetric clinics between February and September 2024. Participants completed online self-administered questionnaires assessing antenatal depression, anxiety, perceived stress, social support, parenting self-efficacy, and maternal–fetal bonding. General Linear Models were used to analyse data and identify factors associated with depression, anxiety, and bonding.
Higher perceived stress was associated with increased depression (β = 0.28, p < 0.001) and anxiety (β = 1.28, p < 0.001) and poorer bonding (β = 0.08, p = 0.02), while greater social support predicted lower anxiety (β = −0.31, p < 0.001). Higher parenting self-efficacy was linked to stronger bonding (β = −0.09, p = 0.06). Younger mothers (β = −2.68, p = 0.025) and Indian mothers (β = 7.46, p = 0.017) were particularly vulnerable to anxiety, whereas post-secondary education was protective against depression (β = −1.44, p = 0.02). Model fit ranged from 0.14 to 0.65.
Perceived stress, social support, and parenting self-efficacy significantly influenced antenatal mental health and bonding in at-risk mothers. These findings underscore the need for culturally sensitive, nurse/midwife-led interventions that integrate early screening, stress reduction, and empowerment strategies within routine antenatal care to strengthen maternal mental health and early bonding outcomes.
(1) Nurses and midwives play a critical role in screening for antenatal depression and anxiety in mothers with risk profiles highlighted in this study. (2) Culturally responsive nursing practice that demonstrates sensitivity towards sociocultural pressures is needed to provide individualised care. (3) Integration of digital and community-based antenatal education programs could provide more equitable access to care for at-risk mothers who may face barriers to in-person care.
(1) Despite having a higher susceptibility for antenatal mental health conditions, risk factors for antenatal depression, anxiety, and maternal–infant bonding have been underexplored in at-risk mothers. (2) Antenatal stress and anxiety are universally associated with depression across risk groups, while maternal self-efficacy and perceived social support serve as key protective factors. (3) The findings from this study suggest the need for early screening and nurse-led interventions that support maternal parenting self-efficacy and stress management to improve maternal mental health outcomes among at-risk mothers.

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.

BackgroundDiabetic kidney disease (DKD) poses a significant health burden with inadequate diagnostic sensitivity. This study develops non-invasive biomarkers by integrating urinary and renal single-cell sequencing with machine learning.
MethodsThis study analyzed DKD single-cell and bulk transcriptomic data from public repositories. We established a computational pipeline to distinguish kidney-originating cells in urinary sediments, enabling the identification of injury-associated gene signatures. These signatures were refined using machine learning to develop a diagnostic model, which was validated in independent cohorts. The biomarkers were further verified in DKD renal tissues at single-cell resolution and across multiple nephropathies. Functional and spatial analyses confirmed biological relevance using transcriptomic and histological validation.
ResultsSingle-cell analysis of 2,089 urine-derived cells identified eight renal cell types, including injured proximal tubule cells (Inj-PTC) showing upregulated injury markers (HAVCR1, VCAM1) and enriched apoptotic/TGF-β pathways. A machine learning-selected biomarker panel (PDK4, RHCG, FBP1) demonstrated strong diagnostic value (area under the curve, AUC > 0.9), with consistent downregulation across multiple chronic kidney diseases. PDK4 and FBP1 were specifically suppressed in DKD renal Inj-PTC (p Conclusions
This study identifies a three-gene biomarker panel (PDK4, RHCG, FBP1) as a promising non-invasive diagnostic tool for DKD. While demonstrating excellent diagnostic performance. It represents a tubular injury-associated gene signature that is detectable in urinary cells and shows strong association with DKD in transcriptomic datasets, presenting a promising candidate for a non-invasive diagnostic assay.
