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.

This prospective longitudinal study of a general population sample investigates whether maternal experience of out-of-home care (OHC) constitutes an independent risk factor for the development of externalising and internalising symptoms in offspring, after adjusting for other commonly associated aetiologic risks.
18 810 families in the UK Millennium Cohort Study with complete information provided by the birth mother regarding her OHC experience and ethnicity.
Offspring externalising and internalising symptoms assessed by the Strengths and Difficulties Questionnaire as reported by the birth mother.
Latent profile analysis of offspring behavioural adjustment trajectories to identify distinct patterns of co-occurring internalising and externalising problem trajectories from age 3 to 17 years. The role of maternal OHC experience and other risk factors as predictors of adjustment patterns were examined descriptively and using multinomial regression.
Five groups of symptom trajectories were identified: two normative groups with very low (33%) and low symptom levels (40%) and three problem behaviour groups including high externalising/moderate internalising (10%), high internalising/high externalising (5%) and moderate internalising/high externalising (12%). Compared with the normative group, higher symptoms were predicted by family socioeconomic status (SES), housing conditions, maternal health, parent–child relationship and child characteristics. Maternal OHC experience was a significant risk factor for all three problem groups, with the highest relative risk (RRR 4.82) observed for children showing high internalising/externalising symptoms. However, after controlling for the other risk factors, maternal OHC experience was no longer significantly associated with higher symptoms.
Maternal OHC experience is associated with an elevated risk of offspring presenting adjustment problems, characterised by co-occurring internalising and externalising symptom trajectories. However, the impact of maternal OHC experience on their children’s adjustment was fully attenuated by other common etiological risks, suggesting that these factors play a critical role in mediating the risk.

This study aimed to optimize microencapsulation conditions for Phy-Blica-O (PBO), a traditional Thai polyherbal tonic, and to assess the safety of its consumer-accepted herbal tea formulation, Phy-Blica-D (PBD). PBO decoction and its phenolic-rich extract were spray-dried at different inlet temperatures (140°C, 180°C) and maltodextrin-gum Arabic ratios. Encapsulation efficiency was highest at 140°C with maltodextrin alone, while antioxidant activity was greatest in microcapsules prepared at 180°C with a 6:4 maltodextrin to gum Arabic ratio, as shown by DPPH, ABTS, and FRAP assays. PBD demonstrated strong in vitro antioxidant activities and was subsequently assessed in a 90-day subchronic toxicity study in Wistar rats. No treatment-related mortality, clinical abnormalities, organ toxicity, or hematological or biochemical disruptions were seen at doses up to 300 mg/kg/day, indicating a NOAEL above this level. These findings suggest that optimized PBO microcapsules and the PBD tea blend are safe, antioxidant-rich functional ingredients with strong potential for commercialization in complementary and integrative medicine.The 2013–2016 Western African outbreak of the Ebola virus disease (EVD), the largest recorded outbreak since the discovery of Ebola virus (EBOV) in 1976, destabilised local health systems and left thousands of survivors at risk for postacute sequelae, including vision-threatening uveitis. In an EVD survivor with severe panuveitis, the detection of persistent EBOV in the aqueous humour, long after clearance of acute viremia, focused clinical and research attention on the host-EBOV interaction in the unique terrain of ocular immune privilege. Despite the recognition that uveitis is common and consequential in EVD survivors, our understanding of pathogenesis is extremely limited, including the contributions of viral persistence and ocular-specific and systemic immune responses to disease expression. In this study protocol, we outline a multifaceted approach to characterise EVD-associated intraocular inflammation, including the clinical phenotype and complications; the presence of EBOV (or EBOV RNA/antigen) in ocular fluids and tissues; and associated local ocular-specific and peripheral immune responses.
We use an observational cohort design, which includes EVD survivors and close contacts of EVD survivors (ie, no documented history of EVD), and we propose disease (clinical examination and imaging), as well as molecular, virologic and immunologic characterisation, to meet research objectives.
This study has received Institutional Review Board approval from University of Nebraska Medical Centre, Emory University and Sierra Leone Ministry of Health. Findings will be disseminated through peer-reviewed publications.

Zambia has achieved improvements in life expectancy among persons living with HIV (PLHIV) because of high antiretroviral therapy (ART) coverage, which should improve survival due to reductions in AIDS-defining conditions. However, recent estimates of the most common causes of death are not widely available. We utilized mortality surveillance data to report on common causes of death among persons with HIV who died in community settings in Zambia. The Zambian Ministry of Health conducted sentinel mortality surveillance of community deaths in 45 hospitals in 33 of 116 districts from January 2020 through December 2023. Verbal autopsies (VA) were conducted through interviews with relatives or close associates of deceased persons using the 2016 World Health Organization tool. HIV status was reported. A probable cause of death was assigned by a validated computer algorithm (InterVA5). We describe the top assigned causes of death stratified by HIV status. Verbal autopsies were conducted for 67,079 community deaths, of which 11,475 (17.1%) were persons with HIV. The mean age at death was 45 years among persons with HIV and 48 years for persons without HIV (T-test pby Moe Thi Thi Han, Tay Zar Myo Oo, Busayamas Chewaskulyong, Sakorn Pornprasert, Kanyamas Choocheep, Khanittha Punturee, Warunee Kumsaiyai, Yupanun Wuttiin, Sawitree Chiampanichayakul, Ratchada Cressey
Non-smoking-related lung cancer is increasingly associated with environmental factors such as particulate matter (PM) exposure. Using deep small RNA sequencing, we identified distinct miRNA expression patterns in lung cancer patients compared to non-cancer controls, stratified by smoking status. Notably, hsa-miR-125b-5p and hsa-miR-100-5p were significantly downregulated in non-smoking lung cancer patients. Pathway enrichment analysis revealed smoking amplifies pathways related to glycan biosynthesis, signal transduction, and transcriptional regulation, while non-smoking lung cancer is characterized by immune dysfunction and metabolic alterations, including oxidative phosphorylation and natural killer cell cytotoxicity. Validation in a larger cohort using quantitative RT-PCR confirmed the suppression of miR-125b-5p and miR-100-5p in non-smoking lung cancer patients. Additionally, miR-203a and miR-199a-3p were identified as potential biomarkers for lung cancer, independent of smoking status. Chronic PM exposure in primary bronchial/tracheal epithelial cells initially elevated miR-125b-5p and miR-100-5p expression, but prolonged exposure suppressed these miRNAs while increasing their target genes, TXNRD1 and HOXA1, suggesting stress-induced dysregulation. Functional studies using miRNA mimics demonstrated that miR-125b-5p and miR-100-5p suppress PM-induced cancer cell mobility and colony formation, with miR-125b-5p exhibiting broader effects. These findings underscore the critical roles of miR-125b-5p and miR-100-5p in PM-associated lung cancer progression and their potential as biomarkers and therapeutic targets. This study highlights distinct mechanisms of lung carcinogenesis in smokers and non-smokers, providing a foundation for targeted interventions in PM-associated lung cancer.To explore peer volunteers' experiences of delivering online support through SMART to at-risk mothers during the perinatal period, to inform future improvements to mobile-health-application (mHealth app) based peer-support interventions.
Descriptive qualitative research.
The study was conducted between February 2024 and June 2025 in a tertiary public healthcare institution in Singapore. Twenty peer volunteers were recruited via convenience and snowball sampling and participated in individual semi-structured interviews. Interviews were audio-recorded, transcribed verbatim and analysed using thematic analysis.
Four themes were identified: (a) Giving and receiving: the inner world of peer volunteers; (b) Navigating relational complexity in digital peer support; (c) Facilitating connection and continuity in digital peer support; and (d) Building better connections through supportive ecosystems.
Peers reported experiencing reciprocal benefits, such as a sense of fulfilment and achievement, while supporting mothers. Shared experiences and psychosocial vulnerabilities enhanced relatability, reassurance and rapport, which sustained supportive relationships. Challenges encountered by peers highlighted the need for strengthening both intervention design and peer training.
Regular check-ins by programme facilitators, alongside clear information, flexible guidelines and reassurance, can improve peer volunteers' motivation and resilience, thereby ensuring consistent and sustainable support for at-risk mothers.
Examined peer volunteers' experiences in providing online perinatal support to mothers with diverse psychosocial vulnerabilities. Peers offered emotional, informational and practical support, while mothers benefited from learning how peers had coped with their psychosocial vulnerabilities. Shared experiences fostered confidence and reassurance among mothers that they, too could overcome similar adversities. Valuable in providing both medically accurate perinatal information and meaningful social support to perinatal mothers.
The reporting of the study adheres to the standards outlined in the Consolidated Criteria for Reporting Qualitative Research (COREQ) checklist.
Mothers and peer volunteers contributed valuable insights and suggestions that helped in the design of the intervention.

Gross anatomy dissection is an essential component of medical and health science education, yet it presents notable occupational hazards, particularly from formaldehyde (FA) exposure and microbial contamination. These risks may be intensified in anatomy dissection halls located in tropical monsoon (Am) climates, where elevated humidity and temperature promote both chemical volatility and microbial persistence. This study assessed the combined effects of such climatic conditions on FA concentrations and microbial ecology within a naturally ventilated dissection hall in southern Thailand. FA levels were measured through personal and area air sampling across seven anatomical regions, while microbial contamination on cadaver-contact surfaces was evaluated using culture-based methods and high-throughput sequencing. Functional prediction of microbial communities was performed using PICRUSt2 to assess their metabolic adaptation to environmental stressors. The results revealed that both personal and indoor FA concentrations (mean 1.17 ± 0.39 ppm and 1.09 ± 0.45 ppm, respectively) exceeded several international occupational exposure limits, with the highest levels observed during dissections involving deep or adipose-rich anatomical regions. Microbial analyses identified stress-tolerant and potentially pathogenic genera, including Bdellovibrio, Aequorivita, and Aspergillus spp., along with enriched pathways involved in aromatic compound degradation and environmental resilience. These findings highlight the limitations of natural ventilation in controlling occupational exposures and microbial contamination in Am climate anatomy laboratories. The study supports the implementation of climate-responsive engineering controls and laboratory management strategies that address chemical safety, thermal regulation, and biosafety to promote healthier and more sustainable dissection environments in similar high-risk settings.Research on the impact of smoking behaviour across generations has primarily focused on grandmaternal smoking during pregnancy. However, the broader multigenerational effects of smoking behaviour, notably through environmental and behavioural pathways, remain underexplored. This study evaluated previous studies on the possibility of transgenerational transmission, rather than in utero transmission, regarding the effects of grandparental smoking behaviour on offspring’s development outcomes.
This study is a systematic review with qualitative evidence synthesis.
A comprehensive search was conducted across multiple online databases, including PubMed, EBSCOhost, Web of Science and Scopus. To ensure a broad scope of relevant studies, publication dates, study locations and language were restricted to English only.
After duplicates were removed, 3916 articles remained from the 4133 identified articles. Based on the predefined eligibility criteria, 38 articles were selected for full-text assessment. The selection process involved multiple reviewers, with disagreements resolved through consensus.
Multiple reviewers independently extracted data using a standardised protocol. The Joanna Briggs Institute critical appraisal tool was used to assess the quality of the included studies, with inter-rater reliability tests indicating moderate-to-high agreement. Extracted data included study design, participant demographics, exposure details and measured outcomes.
This systematic review included seven studies because of heterogeneity in reported outcomes and effect measures. Three independent reviewers extracted data using a standardised coding sheet. The synthesis compared methodologies, identified gaps, key findings and conclusions across studies.
Seven included articles examined grandchildren’s behaviour, such as hyperactivity disorder, oppositional defiant disorder and conduct problems, body composition and IQ concerning grandparents’ smoking habits. Most studies used robust statistical methods; two included parental factors as mediators. The synthesis of results indicated that the associations were primarily indirect. Key findings revealed that grandparents’ smoking status was significantly associated with their grandchildren’s physical and cognitive outcomes. Furthermore, the reviewed studies demonstrated sex-specific transgenerational effects of ancestral smoking on grandchildren’s health, with stronger effects often observed in male descendants.
This review highlights the methods and findings of previous studies on the potential transgenerational transmissions through which grandparents’ smoking behaviour may influence grandchildren’s behavioural, physical and cognitive development. Although the findings emphasise the importance of environmental and behavioural factors, further research is needed to address existing gaps and clarify mechanisms.
This systematic review protocol was registered in the PROSPERO database under registration number CRD42024571725.
Preventable hospital patient harm events disproportionally affect certain patient populations. For some, harm extends beyond physical injury to include cultural, emotional or spiritual impacts. While these disparities are linked to socio-demographics (eg, race, education), they are driven by structural factors (eg, procedures and policies). Patient safety monitoring systems (eg, incident reporting, patient concerns) were not originally designed to identify equity-related harms and may inadvertently obscure or reinforce the injustices they should address. This study will examine how equity is currently considered within hospital incident reporting and patient concerns systems across Canada and will identify opportunities to strengthen these systems’ responsiveness to inequities in patient safety.
This 3-year exploratory sequential mixed-method study began in September 2024. Phase one involves qualitative interviews with patient safety and equity leads, patients/families/caregivers and leaders of innovative initiatives to explore current practices, gaps and innovations in how equity-related factors are identified and addressed within incident reporting and patient concerns systems. Findings will inform Phase 2, a modified Delphi process with patient safety and equity experts and persons with lived experience of equity-related harm events to refine and reach consensus on key equity-promoting features, considerations and recommendations for these systems. In Phase 3, consensus items will be used to develop a national cross-sectional survey assessing the extent to which equity is integrated into hospital incident reporting and patient concerns systems in Canada. A patient advisory committee will inform data collection, interpretation of findings and dissemination.
Ethics approval has been received for Phase 1, with subsequent approvals to be sought for later phases. Dissemination plans include peer-reviewed publications, presentations at international conferences and knowledge exchange activities to inform patient engagement, the design of incident reporting and patient concerns systems and policy development.
High-intensity statin therapy is recommended as a first-line strategy for lowering low-density lipoprotein cholesterol (LDL-C) levels in patients with acute myocardial infarction (AMI). A combination of moderate-intensity statin and ezetimibe at an equivalent dose to high-intensity statin may achieve similar LDL-C reduction with fewer side effects. This study evaluates the long-term efficacy and safety of this approach, initiated following AMI, compared with high-intensity statin monotherapy.
The ROSUZET-AMI trial is a multicentre, prospective, open-label, randomised, non-inferiority trial. Patients with AMI who underwent percutaneous coronary intervention were randomised 1:1 to receive either moderate-intensity statin with ezetimibe (rosuvastatin 5 mg with ezetimibe 10 mg) or high-intensity statin monotherapy (rosuvastatin 20 mg). The primary endpoint is the composite of cardiovascular death, major coronary events (non-fatal myocardial infarction, documented unstable angina requiring hospitalisation and all coronary revascularisation events occurring at least 30 days after randomisation), or non-fatal stroke.
Ethics approval for this study was obtained from the Institutional Review Board of Seoul St. Mary’s Hospital (No. 2020-0424-0003). Informed consent is obtained from every participant before randomisation. The results of this study will be submitted for publication in international peer-reviewed journals, and the key findings will be presented at international scientific conferences.
To examine the perinatal experiences of at-risk mothers and their engagement with mobile-health-based care.
A qualitative descriptive study.
One-to-one semi-structured interviews were conducted with 30 at-risk mothers, defined as those who were single, had low income, were at risk of depression, had adverse childhood experiences, gave birth to a baby with congenital disorders, or had a history of mental health conditions. Participants were purposively sampled at 6 months postpartum from a tertiary public hospital in Singapore between February and September 2024. Interviews continued until data saturation was achieved, were audio-recorded, transcribed verbatim and analysed using thematic analysis.
The study identified four overarching themes: (a) Me and my baby versus the world, (b) navigating vulnerability and strength in motherhood, (c) generational tensions in modern parenting and (d) reimagining perinatal care for every mother. Across the perinatal period, both intervention and control group mothers reported social isolation, emotional and physical strain and challenges balancing traditional family expectations with modern parenting practices. While mothers in the intervention group described receiving holistic support through the SMART program, those in the control group relied on ad hoc sources of support, such as social media platforms.
At-risk mothers experienced significant challenges during the perinatal period, and those who used a mobile-health-based perinatal intervention felt supported through its peer support and multimedia educational resources.
Mobile-health-based interventions can be integral aspects of standard nursing care. Future researchers must ensure that support rendered to at-risk mothers is culturally compatible and specific to the psychosocial vulnerabilities they experience. Increased contact and funding are vital, whereas artificial intelligence, multiple shared access and health monitoring trackers can shape future perinatal interventions.
A mobile-health-based perinatal intervention can have an enormous positive impact on the psychological well-being of vulnerable mothers worldwide.

To evaluate the acceptability and safety of a fluid volume assessment tool integrating clinical signs, patient-reported symptoms and bioimpedance analysis as a clinical decision aid in haemodialysis.
Single-centre, 6-month clinical implementation feasibility pilot study.
A convenience sample of 50 healthcare staff and 50 hospitalised haemodialysis patients was recruited. The intervention involved a fluid volume assessment tool combining clinical signs, patient-reported symptoms and bioimpedance analysis. We utilised the Template for Intervention Description and Replication (TIDieR) checklist to describe the intervention. Nurses used a decision algorithm to guide them in setting the ultrafiltration target. Staff acceptability was assessed using the NoMAD survey, and safety outcomes, including intradialytic hypotension, intradialytic events and fluid overload, were monitored. Trends between Charlson Comorbidity Index scores and safety risks were explored.
The tool achieved high acceptability among staff, with cognitive participation (100%) and collective action (92%) being the strongest domains. Safety analysis indicated minimal adverse events (intradialytic hypotension: 10%, intradialytic events: 12%). Participants with higher Charlson Comorbidity Index scores (> 6) were more likely to experience intradialytic hypotension or intradialytic events, highlighting the need for tailored approaches for these populations.
The tool was acceptable, safe and feasible, empowering dialysis nurses to deliver real-time, individualised fluid management, reducing dependency on nephrologists and addressing operational challenges in the acute setting.
The tool promotes nursing autonomy, enhances care efficiency and ensures safe, patient-centred fluid management in resource-limited settings.
Addresses fluid management challenges in haemodialysis care through introduction of an evidence-based fluid assessment tool. Support a scalable nurse-led protocol for ultrafiltration management, promoting patient safety and workflow efficiency in acute dialysis settings.
