To explore aspects of interpersonal relationships in palliative care nursing, focusing on confidential conversations between patients and registered nurses (RN).
A qualitative study employing focused ethnography.
Data were collected through unstructured participant observations, field notes and interviews with patients and RN in specialist palliative care. Data were analysed using reflective thematic analysis.
Confidential conversations in palliative care are founded on trust that is fragile and develops dynamically through consistent interactions. Small talk, presence and silence are essential for initiating and maintaining trust and the interpersonal relationship. The environment, patient condition and RN emotional presence and competence shape these conversations. As the relationship evolves, conversations adapt to the patient's changing needs. Missed signals or interruptions can disrupt flow, but the potential for repair remains, allowing for restoration and strengthening of trust and connection.
Confidential conversations in palliative care are grounded in fragile, dynamic trust, necessitating ongoing presence, sensitivity and adaptability from RN. To support these interactions, healthcare environments must prioritise privacy, relational continuity and communication training. Future research should investigate how organisational structures and clinical settings influence confidential conversations.
Healthcare environments should facilitate confidential conversations by ensuring relational continuity and minimising distractions. Communication training that emphasises presence and management of silence can strengthen nurse–patient relationships, enhancing patient care and emotional support.
This study explores key aspects of confidential conversations in palliative care, emphasising trust and emotional sensitivity. It addresses a research gap in palliative care using rare observational methods to deepen understanding of nursing relational aspects. The findings offer practical guidance for enhancing communication and relational skills, informing training and policy development and ultimately, improving emotional support and care.
Findings are reported in accordance with the Consolidated Criteria for Reporting Qualitative Research guidelines.

To analyse current Glasgow Coma Scale practice among emergency nurses in China and identify factors influencing assessment quality.
A quantitative, multicenter cross-sectional design.
A convenience sample of 1740 emergency nurses from secondary and tertiary hospitals across 21 provinces completed a validated structured questionnaire between March and April 2025. Participants had at least 6 months of emergency nursing experience. Data analysis included descriptive statistics, chi-square tests, and multiple logistic regression to examine factors influencing correct Glasgow Coma Scale application.
Participants had a mean age of 29.8 years (SD = 6.2). Only 52.5% of nurses demonstrated correct Glasgow Coma Scale application despite 97.0% having theoretical knowledge of scoring criteria. While 56.8% had received Glasgow Coma Scale training, significant standardisation deficiencies emerged. Notably, 41.8% of departments lacked operational guidelines, and 53.7% of nurses experienced scoring disagreements with colleagues. Clinical utilisation varied substantially by patient population: traumatic brain injury (97.8%), neurological diseases (96.9%), and systemic critical illness (85.8%). Multivariate analysis identified six significant factors influencing correct application: standardised training (OR = 2.252, 95% CI: 1.789–2.825), manageable workload ≤ 4 patients/shift (OR = 1.652, 95% CI: 1.327–2.057), departmental guidelines (OR = 1.523, 95% CI: 1.233–1.881), extensive work experience ≥ 9 years (OR = 1.534, 95% CI: 1.182–1.992), while multidisciplinary collaboration issues (OR = 0.559, 95% CI: 0.439–0.712) and special patient experience (OR = 0.520, 95% CI: 0.406–0.666) were associated with reduced accuracy.
Substantial standardisation challenges exist in Glasgow Coma Scale practice among Chinese emergency nurses, characterised by significant gaps between theoretical knowledge and clinical application. Major barriers include insufficient standardised guidelines, inconsistent training approaches, and inadequate interdisciplinary collaboration.
Healthcare administrators should develop national standardised guidelines, implement simulation-based training programs, optimise emergency workflows, and integrate alternative assessment tools to enhance consciousness assessment accuracy and improve patient safety.

To critically synthesise current literature on the nurses' experiences in providing care for people presenting with mental health issues to the emergency department (ED).
Mental health-related presentations to EDs are increasing. Understanding nurses' experiences of providing care for this patient group will inform future strategies to enhance the care delivered in the ED.
CINAHL, MEDLINE, APA PsycInfo and Psychology and Behavioural Sciences Collection were searched from 2009 to 2024 for peer-reviewed qualitative papers exploring emergency nurses' perspectives of providing care for people with mental health issues, published in the English language. Quality was appraised using the JBI Critical Appraisal tool. This review follows the PRISMA checklist for reporting.
Nine papers, reporting eight studies, were included in the review. Three themes emerged: attitudes towards mental illness, education limitations impacting confidence and structural barriers impacting care quality. The review reveals a disconnect between nurses' compassionate intentions and barriers such as unconscious stigma and prioritising physical illness over mental health concerns. The findings highlight the need for targeted mental health education to enhance ED nurses' confidence and competence. Inadequate local mental health policies also impact care delivery, contributing to suboptimal patient outcomes.
This review provides a deeper understanding of ED nurses' experiences of caring for people with mental health issues. A need to implement a multifaceted approach to mental health education, clear policies to guide care delivery and systems that promote prioritisation of patients presenting with mental health concerns was identified.
Insights into nurses' experiences can shape future ED practices and enhance outcomes for patients. Building ED nurses' capacity to deliver high-quality mental health care is critical.
As a review paper, no patient or public consultation took place.
To identify distinct social network types among young-old adults based on the characteristics of social network structure and to explore the relationship between different types, socio-demographic characteristics and subjective cognitive decline.
A cross-sectional study was conducted from July 2022 to October 2023.
A total of 652 young-old adults aged 60–74 years completed the sociodemographic questionnaire, the subjective cognitive decline questionnaire-9 and the self-designed egocentric social network questionnaire. The types of social networks were identified by latent profile analysis. Univariate analysis and binary logistic regression were used to analyse the influencing factors of subjective cognitive decline.
The incidence of subjective cognitive decline was 38%. Social networks of young-old adults tended to be large, predominantly family-centred and characterised by strong contact strength, high density and significant demographic heterogeneity among network members. Four social network types were identified: diverse-moderate, family-dense, family-strong and friend-loose. Young-old adults embedded in the family-dense and family-strong types were more likely to develop subjective cognitive decline than those in the diverse-moderate type. Additionally, age, education level, previous occupation, daily sleep duration and exercise were related to the incidence of subjective cognitive decline.
The findings highlight the relatively high incidence of subjective cognitive decline in young-old adults that is notably influenced by the type of social network they are embedded in. More attention needs to be paid to identifying and supporting young-old adults at high risk of subjective cognitive decline, especially to promote their social integration and friend network building, to improve their subjective cognitive function.
The findings emphasise the importance of considering the structure and composition of social networks when addressing subjective cognitive decline among young-old adults. A diversified social network incorporating both familial and friendship ties may provide enhanced cognitive protection. Therefore, interventions targeting subjective cognitive decline should promote the expansion of friendship-based relationships and foster the development of more heterogeneous and multi-source networks.

Interprofessional socialisation can contribute to collaborative patient care. Although there is research regarding interprofessional socialisation of healthcare students and frontline staff, there is limited literature regarding healthcare educators in practice settings. Our aim was to examine interprofessional socialisation of healthcare educators in the practice setting following an interprofessional simulation facilitator training programme.
Explanatory sequential mixed methods study.
Quantitative provincial simulation programme evaluation data from 2022 and 2023 (n = 87) were analysed and used to inform qualitative interviews (n = 17). Qualitative and quantitative data were integrated following independent analysis.
There was a statistically significant increase in attitudes toward interprofessional socialisation following the simulation facilitator training programme. Qualitative findings revealed themes regarding interprofessional socialisation: (a) benefits gained through interprofessional socialisation, (b) interprofessional, uniprofessional or both, (c) facilitators to interprofessional socialisation, (d) barriers to interprofessional socialisation and (e) opportunities to strengthen interprofessional socialisation.
Despite positive views of interprofessional socialisation, socialisation behaviours may not be consistent in a variety of contexts. Interprofessional education may increase interprofessional socialisation among educators.
It is important to provide interprofessional socialisation opportunities for educators to promote more interprofessional education initiatives.
The findings of this study provided insights into how to foster interprofessional socialisation in existing structures and how new pathways might be built to connect educators.
This study is reported in congruence with the Journal Article Reporting Standards—Mixed Methods, Quantitative, and Qualitative Standards provided on the Equator Network.

To identify research gaps by mapping what is known about the barriers and enablers to pre-registration nursing students identifying signs of suicidal distress in healthcare consumers and providing clear pathways of support.
Scoping review.
This scoping review was conducted using Arksey and O'Malley's (2005) five stage framework and the Levec et al. (2010) extensions of this framework.
The Cumulative Index of Nursing and Allied Health Literature (CINAHL) Complete and Ovid MEDLINE databases were searched to identify relevant articles, keywords and search terms to inform the full search strategy for CINAHL. This search strategy was then adapted for Scopus, PsychInfo, Emcare, Medline and ERIC, searched in November 2024.
Studies eligible for inclusion (N = 28) represented research from 14 countries; most (53.5%, n = 15) used a quantitative design, 11 (39.3%) were qualitative and two (7.1%) used a mixed-methods design. Barriers found from the scoping review included a low level of knowledge of suicidality, stigma preventing students from assessing and acting on suicidal ideation, and a lack of confidence in providing care to healthcare consumers expressing suicidality. Enablers included lived experience, exposure to individuals expressing suicidal ideation and education, simulation and role play. This review also contributes to the existing literature about the relationship of nursing to existing suicide prevention frameworks and suggests revision of these frameworks to address staff attitudes and beliefs, as well as lived and living experience.
Nurses are ideally placed to assess and respond to suicidality among healthcare consumers, and preparation should begin during pre-registration studies. Our scoping review indicates that further research work is needed to address the barriers to working with healthcare consumers expressing suicidality and to enhance the enablers to provide safe care.
Addressing the barriers and enablers to pre-registration nursing students providing safe care for healthcare consumers expressing suicidality is essential. Further research is required to address the barriers and enhance the enablers identified in this scoping review.
What problem did the study address? This scoping review summarised the literature on pre-registration student ability to work with healthcare consumers expressing suicidality, identifying barriers and enablers. What were the main findings? Barriers include poor knowledge of suicidality, stigma, fear and a lack of confidence in working with healthcare consumers expressing suicidality. Enablers include lived experience, exposure to clinical settings where healthcare consumers express suicidality and simulation and education. Where and on whom will the research have an impact? The research will have an impact on providers of pre-registration nursing degrees, where the inclusion of content addressing suicidality and exposure to settings where individuals express suicidal ideation is shown to improve attitudes and knowledge of suicidality assessment.

Although healthcare infrastructure has improved in recent years, the preoperative journey of patients is often accompanied by anxiety. Allowing patients to walk to the operating theatre is a simple, yet underexplored strategy that may enhance their sense of autonomy and reduce anxiety. As patient-centred care gains importance, evaluating the effects of this approach on patient-reported outcomes may be more relevant than widely assumed.
In this scoping review, we aim to analyse the published literature on preoperative walking into the operating theatre and patient-reported outcomes, such as anxiety and satisfaction.
This study was a scoping review that followed the Joanna Briggs Institute methodology and Preferred Reporting Items for Systematic Reviews and Meta-Analyses, Scoping Review extension guidelines.
Inclusion criteria were adult patients undergoing elective surgery and walking to the operating theatre. Data were extracted using a standardised form, and critical appraisal was performed by using ROBINS-I V2.0, RoB2 and ROB-E tools.
Embase, MEDLINE, Cochrane databases (OVID) and CINAHL (EBSCOhost) were searched up to 31st January 2025.
Our search identified 958 articles, with seven trials included in the final analysis. The studies, published between 1994 and 2022, involved 3001 patients from North America, Asia and Europe. The interventions varied, but most patients reported improved satisfaction and reduced anxiety when walking to the operating theatre. No adverse events were reported, although patient preferences varied, with younger patients more likely to prefer walking.
Walking to the theatre positively impacts patient satisfaction and autonomy. However, patient selection is key, as not all individuals are physically or mentally prepared for walking. Future research could explore unaccompanied walking and its effects on hospital resource utilisation. Preoperative walking is a beneficial intervention that enhances patient satisfaction and reduces anxiety, providing a feasible alternative to bed transport for many elective surgical patients.

To assess the supply, demand, and utilisation of master's degree nurses in China's top-tier hospitals and identify recruitment and retention challenges.
A convergent parallel mixed-methods design.
From January and September 2022, eight top-tier hospitals in mainland China were selected using convenience sampling. The proportion of master's degree nurses, turnover rates, and recruitment outcomes were investigated and analysed using descriptive statistics. Concurrently, seven nursing administrators from these eight hospitals were interviewed using semi-structured interviews, and transcribed data were thematically analysed through inductive content analysis.
Among the eight hospitals surveyed, the average proportion of master's degree nurses was 3.58% (range: 0.58%–9.43%). The average ratio of planned to actual recruitment was 3.28, with four hospitals showing near parity (approximately 1:1) and three institutions failing to recruit any master's degree nurses. The annual turnover rate of master's degree nurses was 1.18%. Three themes emerged from the qualitative analysis: (1) shortages coexisting with oversupply; (2) nursing leaders' retention efforts versus limited institutional policy support; and (3) prioritisation of research and management over advanced clinical roles.
In China, even among top-tier hospitals, the proportion of master's degree nurses remains relatively low. There is an overall shortage of these nurses, juxtaposed with localised oversupply in specific institutions. Promotion to nursing supervisor or administrative roles is the only developmental pathway, while structured career progression pathways for advanced nursing practice remain conspicuously absent.
The study highlights the need to develop targeted policies that support the career advancement of master's degree nurses, particularly by expanding career options in Advanced Practice Nurses (APNs) rather than limiting roles to nursing management or education. This shift would better leverage their clinical expertise and strengthen healthcare systems through specialised practice and innovation.
What problem did the study address?: This study maps the supply–demand dynamics of master's degree nurses in leading hospitals and identifies retention, utilisation, and motivation policies and strategies from the perspective of nursing administrators. What were the main findings?: The proportion of master's degree nurses is low in China's top hospitals. There is both an oversupply and a shortage of master's degree nurses. Neither the government nor hospitals have policies in place to encourage the clinical involvement of master's degree nurses, and their career progression is limited to managerial roles. Where and on whom will the research have an impact?: Nursing administrators and other health policy makers in China and comparable global health systems will be affected. It will also influence nursing associations, nursing educators, and general nurses.

To explore healthcare professionals', patients', and family members' experiences of managing regular medications across the perioperative pathway in a specialist cancer hospital in Melbourne.
An exploratory qualitative study using a descriptive-interpretive approach.
Interviews were conducted with 11 patients and seven family members, and focus groups with 10 anaesthetists, seven surgeons, four nurses, and 10 pharmacists (N = 49) between October 2024 and April 2025. Transcripts were analysed using Braun and Clarke's reflexive thematic approach and mapped into the Systems Engineering Initiative for Patient Safety (SEIPS) 2.0 human factors framework.
Three interrelated themes were constructed: (1) Work system elements shaping perioperative medication management, encompassing medication and surgical contexts, documentation gaps, reliable medication information, communication infrastructures, roles and responsibilities, and perioperative area resources; (2) Processes influencing medication management practice, characterised by continuity of care at transition points and flagging processes, interdisciplinary collaboration and role interpretation in medication management, patient involvement, family member involvement, and healthcare professional perspectives; and (3) Outcomes of medication management, including patient and organisational outcomes, such as workflow inefficiencies, procedure cancellations, and unplanned readmissions.
Findings indicated that addressing the complexity of perioperative medication safety demands coordinated contributions across multiple professional disciplines. Strengthening interdisciplinary collaboration, clarifying shared responsibilities, embedding structured reconciliation processes at transitions of care, standardizing communication protocols, and involving patients and families are all critical strategies.
This study highlights the need for interdisciplinary coordination and clear role definitions, with nurses as the key contributor, to support collaborative medication decisions in perioperative cancer care.
This study explored challenges in managing regular medications during cancer surgery, offering insights to guide safer practices for perioperative teams, patients, and families in cancer care settings.

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

This study aimed to examine the level of vicarious posttraumatic growth among intensive care unit nurses in China and explore the mediating role of death coping ability in the relationship between moral resilience and vicarious posttraumatic growth.
A multicentre, cross-sectional study was conducted in accordance with the STROBE guidelines.
Between January and March 2025, a questionnaire survey was conducted among 666 intensive care unit nurses from nine tertiary Grade A hospitals across five provinces in China. Participants completed three standardised instruments: the Rushton Moral Resilience Scale, the Coping with Death Scale–Short Version, and the Vicarious Posttraumatic Growth Inventory. We used IBM SPSS 27.0 for descriptive statistics, univariate analyses, and correlation analyses, and employed AMOS 27.0 to perform structural equation modelling for testing mediation effects.
Intensive care unit nurses demonstrated a moderate level of vicarious posttraumatic growth. Moral resilience was positively associated with both death coping ability and vicarious posttraumatic growth. Death coping ability was found to play a partial mediating role in the relationship between moral resilience and vicarious posttraumatic growth.
Moral resilience and death coping ability are key factors associated with vicarious posttraumatic growth among intensive care unit nurses. Nurses with stronger moral resilience are more likely to cope constructively with death-related stress, which may support psychological growth in trauma-intensive environments.
This study highlights the need to enhance intensive care unit nurses' moral and emotional capacities through ethics education, emotional coping training, and institutional support strategies. Strengthening these competencies may foster professional development and mental wellbeing in critical care settings.

Vascular dementia (VaD), a neurodegenerative disease driven by vascular pathology, requires multi-targeted therapeutic strategies. This study employs an integrated in silico approach to evaluate the neuroprotective potential of natural ligands against key proteins implicated in VaD pathogenesis. Using molecular docking and normal mode analysis (NMA), four natural compounds (Galangin, Resveratrol, Curcumin, and Licocumarone) were assessed for their binding affinity and structural influence on six target proteins: APLP1, APOE, CLDN5, SOD1, MMP9, and MTHFR. Docking analysis revealed that galangin exhibited the highest binding affinity to APLP1 (−8.5 kcal/mol), resveratrol to MTHFR (−8.1 kcal/mol), and curcumin showed dual efficacy toward APOE (−7.2 kcal/mol) and MMP9 (−8.0 kcal/mol). Licocumarone demonstrated notable stabilization of CLDN5 and SOD1. The NMA results indicated ligand-induced stabilization of protein cores and enhanced flexibility in loop regions, which may impact amyloid aggregation, oxidative stress, and blood-brain barrier integrity. Pathway enrichment using the KEGG and Reactome databases identified significant involvement of the IL-17 and TNF signaling pathways, along with leukocyte transendothelial migration, linking inflammation with vascular dysfunction. APOE emerged as a central node within the protein-protein interaction network, highlighting its regulatory importance. This study highlights the therapeutic relevance of natural ligands as cost-effective modulators of multiple VaD-associated pathways. The combined use of molecular docking, protein dynamics, and enrichment analyses provides a comprehensive computational framework for early-stage drug discovery. These findings warrant further experimental validation to advance the development of targeted, mechanism-driven interventions for vascular dementia.by Andrea C. Aplasca, Peter B.

Amphibian skin is integral to promoting normal physiological processes in the body and promotes both innate and adaptive immunity against pathogens. The amphibian skin microbiota is comprised of a complex assemblage of microbes and is shaped by internal host characteristics and external influences. Skin disease is a significant source of morbidity and mortality in amphibians, and increasing research has shown that the amphibian skin microbiota is an important component in host health. The Eastern hellbender (Cryptobranchus alleganiensis alleganiensis) is a giant salamander declining in many parts of its range, and captive-rearing programs are important to hellbender recovery efforts. Survival rates of juvenile hellbenders in captive-rearing programs are highly variable, and mortality rates are overall poorly understood. Deceased juvenile hellbenders often present with low body condition and skin abnormalities. To investigate potential links between the skin microbiota and body condition, we collected skin swab samples from 116 juvenile hellbenders and water samples from two holding tanks in a captive-rearing program. We used 16s rRNA gene sequencing to characterize the skin and water microbiota and observed significant differences in the skin microbiota by weight class and tank. The skin microbiota of hellbenders that were housed in tanks in close proximity were generally more similar than those housed physically distant. A single taxa, Parcubacteria, was differentially abundant by weight class only and observed in higher abundance in low weight hellbenders. These results suggest a specific association between this taxa and Low weight hellbenders. Additional research is needed to investigate how husbandry factors and potential pathogenic organisms, such as Parcubacteria, impact the skin microbiota of hellbenders and ultimately morbidity and mortality in the species.by Tanya N.

Sarcoptes scabiei causes a fatal disease (mange) in bare-nosed wombats (BNWs) (Vombatus ursinus) across their range and can threaten isolated populations with extinction. Repeated dosing of moxidectin (Cydectin®) at a dosage rate of 0.5 mg/kg is effective at treating individual BNWs but is difficult to administer on a population basis where treatment success has varied. This paper documents the temporary (~20 month) eradication of mange from a semi-isolated population of BNWs using repeated dosing of Cydectin® administered by burrow flaps. Treated BNWs were marked with nontoxic paint and selected burrows were monitored with camera traps demonstrating that 64–96% of wombats in the population were treated with each dosage. Treatment success was attributed to the installation of burrow flaps on all burrows in the treated area. This treatment program shows that isolated high-density populations can be successfully treated for S. scabiei infection with repeated dosages of Cydectin® (0.5 mg/kg) and questions the need for higher dosages that have been advocated. Mange returned to the population of BNWs after 20 months possibly as the result of migration of an infected BNW from a nearby population, suggesting mange affected populations may require periodic retreatment. Monitoring of burrow entrances confirmed that burrows provide habitat used by many species of birds, reptiles, and mammals, and suggest burrows could be occasional sites of mange spillover among species. Camera trap monitoring also showed when BNWs in this population leave and return to their burrows; how many BNWs enter a burrow and explore the burrow entrances each night; and how these parameters are impacted by season and mange status; variables that are valuable to know when treating populations of BNW for mange.by Jinghui Xie, Haofang Guan, Maohui Liu, Weijun Ding
BackgroundCurrent obesity treatments include behavioral interventions, pharmacotherapy and surgery. Recently, the combination of ‘medicinal food’ products such as the plant Crataegus pinnatifida and its interaction with the gut microbiota has shown promise as an alternative therapeutic strategy to treat obesity.
MethodsWe obtained secondary metabolites (SMs) of obesity-related gut microbiota and Crataegus pinnatifida from gutMGene database and NAPSS database. bioinformatics analysis was used to elucidate key target and signaling pathways, whereas molecular docking (MD), molecular dynamics simulation and quantum chemical calculations identified crucial SMs involved in these pathways. The toxicity and physicochemical properties of these SMs were also assessed.
ResultsPhosphoinositide-3-kinase regulatory subunit 1 (PIK3R1), a key mediator in the phosphoinositide 3-kinase (PI3K)/ Protein Kinase B (Akt) pathway that is crucial for regulating insulin signaling and adipogenesis, emerged as the central hub within the PPI network. Strong binders to PIK3R1 were predicted to be quercetin, kaempferol and naringenin chalcone, suggesting their potential as therapeutic agents to treat obesity.
ConclusionThe synergistic combination of Crataegus pinnatifida and the obesity-related gut microbiota holds promise as a novel therapeutic strategy for obesity by targeting PIK3R1 and modulating the PI3K/Akt signaling pathway. Further experimental validation is necessary to confirm these findings.

Recent wildfires near vineyards in the Pacific United States have caused devastating financial losses due to smoke taint in wine. When wine grapes (Vitis vinifera) are exposed to wildfire smoke, their berries absorb volatile phenols derived from the lignin of burning plant material. Volatile phenols are released during the winemaking process giving the finished wine an unpleasant, smokey, and ashy taste known as smoke taint. Bacteria are capable of undergoing a wide variety of metabolic processes and therefore present great potential for bioremediation applications in many industries. In this study, we identify two strains of the same species that colonize the grape phyllosphere and are able to degrade guaiacol, a main volatile phenol responsible for smoke taint in wine. We identify the suite of genes that enable guaiacol degradation in Gordonia alkanivorans via RNAseq of cells growing on guaiacol as a sole carbon source. Additionally, we knockout guaA, a cytochrome P450 gene involved in the conversion of guaiacol to catechol; ΔguaA cells cannot catabolize guaiacol in vitro, providing evidence that GuaA is necessary for this process. Furthermore, we analyze the microbiome of berries and leaves exposed to smoke in the vineyard to investigate the impact of smoke on the grape microbial community. We found smoke has a significant but small effect on the microbial community, leading to an enrichment of several genera belonging to the Bacilli class. Collectively, this research shows that studying microbes and their enzymes has the potential to identify novel tools for alleviating smoke taint.by Carol Kotliar, Lisandro Olmos, Martín Koretzky, Ricardo Jauregui, Tomás Delía, Oscar Cingolani
ObjectiveTo evaluate the effectiveness of the Mental Training Tech 24.5 (MTT24.5) cognitive stimulation program, designed to enhance cognitive performance and neuroplasticity in healthy adults.
BackgroundCognitive decline is a significant concern in aging populations, with research suggesting that neuroplasticity and cognitive reserve can be enhanced through targeted cognitive training. The MTT24.5 program aims to stimulate brain function through a combination of new knowledge acquisition (DATA) and learning techniques (TECHS), organized into a systematic algorithm. This approach may offer a novel way to prevent or mitigate age-related cognitive decline.
DesignPilot clinical study, active-controlled, open randomization.
SettingAdults from the general population with no clinical cognitive deterioration, recruited from three sites within the Autonomous City of Buenos Aires and its metropolitan area.
Participants120 volunteers were enrolled, of which 76 participants (56 in the intervention group, 20 in the control group) met the study requirements and selected a site closest to their residence.
MethodsThe MTT24.5 program consists of 12 weekly in-person sessions (totaling 24.5 hours), during which participants learned 40 knowledge units (DATA) and 100 learning techniques (TECHS). These were organized into binomials, where each unit of DATA was paired with 3–4 TECHS. Pre- and post-intervention assessments included medical history, lifestyle factors, cognitive reserve scale, Addenbrooke’s Cognitive Examination-Revised (ACE-R), and Mini-Mental State Examination (MMSE).
ResultsThe mean age was 59 years for both groups. Baseline ACE-R scores were comparable (91.3). The global cognitive score increased by 4.6 points (5%) in the intervention group compared to a decrease of 0.5 points in the control group (p Conclusions
The MTT24.5 program, based on a systematic algorithm for acquiring new knowledge and skills, significantly enhances cognitive reserve and overall cognitive performance, particularly in individuals with lower baseline cognitive scores. These findings suggest that structured cognitive stimulation could play a critical role in preventing cognitive decline and promoting cognitive health in healthy adults. Given the promising results, future studies involving larger populations and long-term follow-up are essential to validate these effects and explore the potential for mitigating age-related cognitive decline and enhancing quality of life.
RegistrationThe study was registered in accordance with local regulations at the National Council for Scientific and Technological Research (CONICET) – Institute of Biomedical Research (BIOMED), and also in the National Ethics Committee, and at clinicaltrials.gov (NCT06549517).

Hair follicle stem cells (HFSCs) play critical roles in adult hair regeneration, owing to its self-renewal and multipotent differentiation properties. Emerging evidence has shown that long noncoding RNAs (LncRNAs) are implicated in biological processes such as proliferation, differentiation and apoptosis. However, the specific role of LncRNA RP11-818O24.3 in regulating HFSCs remains unclear. To explore the effect of LncRNA RP11-818O24.3 on HFSCs, stable LncRNA RP11-818O24.3 overexpression and knockdown HFSCs were established using a lentivirus vector system. The effect of LncRNA RP11-818O24.3 on proliferation was evaluated by Cell Counting Kit-8 (CCK8) and EdU incorporation experiments. The differentiation of HFSCs into neurons and keratinocyte stem cells was detected by immunofluorescence staining. We showed that LncRNA RP11-818O24.3 overexpression promoted the proliferation and inhibited cell apoptosis in HFSCs. High levels of LncRNA RP11-818O24.3 promoted the differentiation of HFSCs into CD34+K15+ keratinocyte progenitors and CD34+Nestin+neuron-specific enolase (NSE)+ neural stem cells. Additionally, LncRNA RP11-818O24.3 increased fibroblast growth factor 2 (FGF2) expression and the subsequent activation of the PI3K/AKT signaling pathway. These data demonstrated that LncRNA RP11-818O24.3 promotes self-renewal, differentiation, and the capability to inhibit apoptosis of HFSCs via FGF2 mediated PI3K/AKT signaling pathway, highlighting its potential role as a therapeutic strategy for treating hair loss diseases.
