Medication administration errors are high-risk patient safety issues that could potentially cause harm to patients, thereby delaying recovery and increasing length of hospital stay with additional healthcare costs. Nurses are pivotal to the medication administration process and are considered to be in the position to recognize and prevent these errors. However, the effectiveness of interventions implemented by nurses to reduce medication administration errors in acute hospital settings is less reported.
To identify and quantify the effectiveness of interventions by nurses in reducing medication administration errors in adults' inpatient acute hospital.
A systematic review and meta-analysis was conducted up to 03/24. Six databases were searched. Study methodology quality assessment was conducted using the Joanna Briggs Institute (JBI) critical appraisal tools, and data extraction was conducted. Meta-analysis was performed to combine effect sizes from the studies, and synthesis without meta-analysis was adopted for studies that were not included in the meta-analysis to aggregate and re-examine results from studies.
Searches identified 878 articles with 26 studies meeting the inclusion criteria. Five types of interventions were identified: (1) educational program, (2) workflow smart technologies, (3) protocolised improvement strategy, (4) low resource ward-based interventions, and (5) electronic medication management. The overall results from 14 studies included in meta-analysis showed interventions implemented by nurses are effective in reducing medication administration errors (Z = 2.15 (p = 0.03); odds ratio = 95% CI 0.70 [0.51, 0.97], I 2 = 94%). Sub-group analysis showed workflow smart technologies to be the most effective intervention compared to usual care. Findings demonstrate that nurse-led interventions can significantly reduce medication administration errors compared to usual care. The effectiveness of individual interventions varied, suggesting a bundle approach may be more beneficial. This provides valuable insights for clinical practice, emphasizing the importance of tailored, evidence-based approaches to improving medication safety.
PRISMA guided the review and JBI critical appraisal tools were used for quality appraisal of included studies.
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 examine the personal characteristics, promoting factors and organisational barriers to the professional realisation of diabetes nurse practitioners in Israel.
A descriptive study using quantitative and qualitative data.
The participants self-completed an electronic questionnaire, which included questions on demographic and professional characteristics and a self-realisation questionnaire constructed by the authors. Researcher-led focus groups were conducted, guided by a semi-structured guide. The discussions were recorded, transcribed and analysed by qualitative methods.
Forty-one diabetes nurse practitioners (median age 50 years, 98% females) participated in the study. On average, the participants reported a relatively high self-realisation of their professional role, especially those who have been working in this role for many years. While some of them work independently and are supported by their organisation, their managers and other healthcare team members, specifically physicians, many feel that there are barriers to the full implementation of the role and achieving professional realisation. These include multitasking challenges and insufficient remuneration. Self-realisation was viewed by the participants as an opportunity to provide excellent care to patients as well as being professional beyond caring for patients. They wanted to expand their knowledge as well as guide and teach. Furthermore, they also associated self-realisation with the autonomy to carry out procedures and make decisions independently of physicians. Internal motivation was perceived as an important factor for personal self-realisation, which stems from personal creativity, aspiration for excellence, a subjective sense of freedom, self-guidance, desire for self-development and aspiration for personal growth at the highest levels.
Recognition and fostering of diabetes nurse practitioners' role contribute to nurses' self-realisation and professional growth.
Personal and organisational factors should be aligned to support diabetes nurse practitioners in delivering high-quality care to patients with diabetes.

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.

This study aimed to describe the types of psychological and physical symptoms experienced by healthcare professionals who became second victims after a patient safety incident and the impact of the incident on their social and professional lives.
Scoping review.
JBI methodology for scoping reviews and PRISMA-ScR for reporting were followed.
The search was conducted on June 13, 2024, using the CINAHL (EBSCO), Scopus, PubMed (Medline), Medic and PsycInfo (EBSCO) databases. A grey literature search was also conducted.
A total of 96 papers were included. Healthcare professionals experienced psychological symptoms such as anger, sadness and guilt after a safety incident. Physical symptoms were reported, including symptoms related to sleep and gastrointestinal symptoms. At the professional and social levels, the incident affected their work, relationships and well-being. Positive impacts were also noted.
This study provides a comprehensive overview of healthcare professionals' experiences after safety incidents. In addition, this study also captured the positive impacts of safety incidents, such as learning from mistakes.
By recognising the symptoms and impacts associated with the second victim syndrome, appropriate support can be provided for healthcare professionals.
The findings of this study can be used to identify the relevant harm to professionals after a safety incident, which could help to improve the well-being of these workers.

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.

This review explores the roles, competencies, and scope of practice of APNs in critical care based on international literature. It also derives implications for the development of advanced nursing roles in Austria.
Integrative review.
The research team conducted a systematic search of PubMed, CINAHL, and Web of Science to identify relevant peer-reviewed publications from 2007 to 2023.
A systematic search of electronic databases was undertaken, following Whittemore and Knafl's five-step methodology. The included publications met the defined inclusion criteria and were appraised for quality using the Joanna Briggs Institute critical appraisal checklists. Relevant data were extracted and thematically analysed.
The analysis of 14 international studies revealed recurring themes related to APN core competencies and scope of practice in critical care. These were structured according to Hamric's model. However, Austria faces several challenges, including limited legal frameworks, missing educational structures, and a lack of role clarity. These factors hinder the implementation of APN roles.
Internationally, APNs demonstrate advanced clinical skills, provide leadership in team-based care, and integrate evidence-based practice. These attributes enhance patient outcomes and system efficiency. In Austria, restrictive regulations, limited education, and unclear roles hinder these competencies. Reform is needed to align with international standards, and further research should explore their implementation in Austria.
A gap exists between internationally demonstrated APN competencies and the current state of advanced nursing practice in Austria. This highlights the need for clearer role definitions, regulatory frameworks, and educational strategies. Addressing this gap would strengthen APN roles and improve healthcare quality. This study highlights the need to bridge this disparity.
This review follows the PRISMA 2020 guidelines for systematic reviews Page et al. (2021).

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.

To examine the decision-making processes underlying missed nursing care.
A qualitative study using Critical Incident Debriefing interviews.
Fifteen nurses from inpatient wards in a general hospital participated in semi-structured interviews following their morning shifts. Interviews focused on care prioritisation incidents leading to missed nursing care. Data were analysed using thematic analysis.
Analysis revealed a central theme of emotions as crucial determinants in care prioritisation decisions. Two subthemes emerged: emotions as drivers of care prioritisation decisions and emotions as responses to these decisions. Positive emotions motivated nurses to prioritise care for specific patients, while negative emotions sometimes led to care delays. Successful care completion generated professional satisfaction, while care omissions produced complex emotional responses, including guilt, frustration and helplessness.
The dual emotional processes identified in this study—emotions functioning as both drivers and responses in care decisions—challenge purely structural explanations of missed nursing care. This perspective reframes nurses as emotionally engaged decision-makers who actively navigate care priorities rather than passively react to contextual constraints, offering a more comprehensive framework for understanding the complexity of clinical judgement in real-world settings.
This study positions emotions as legitimate components of clinical decision-making rather than cognitive biases. For nursing practice, this necessitates integrating emotional awareness into professional development. For patient care, recognising emotional underpinnings may promote equitable care distribution through interventions that engage with the emotional realities of nursing work.
This study addressed limited understanding of decision-making in missed nursing care, particularly emotions' role. Findings reveal how emotions influence nurses' prioritisation decisions and wellbeing, with implications for nurses, educators and administrators seeking interventions addressing structural and emotional dimensions.
This study adhered to the Standards for Reporting Qualitative Research (SRQR) guidelines (Appendix S1).

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.

BackgroundDuring public health crises such as the COVID-19 pandemic, decision-makers relied on infectious disease models to evaluate policy options. Often, there is a high degree of uncertainty in the evidence base underpinning these models. When there is increased uncertainty, the risk of selecting a policy option that does not align with the intended policy objective also increases; we term this decision risk. Even when models adequately capture uncertainty, the tools used to communicate their outcomes, underlying uncertainty, and associated decision risk have often been insufficient. Our aim is to support infectious disease modellers and decision-makers in interpreting and communicating decision risk when evaluating multiple policy options.
MethodsWe developed the Decision Uncertainty Toolkit by adapting methods from health economics and infectious disease modelling to improve the interpretation and communication of uncertainty. Specifically, we developed a quantitative measure of decision risk as well as a suite of risk visualizations. We refined the toolkit contents based on feedback from early dissemination through conferences and workshops.
ResultsThe Decision Uncertainty Toolkit: (i) adapts and extends existing health economics methods for characterization, estimation, and communication of uncertainty to infectious disease modelling, (ii) introduces a novel risk measure that quantitatively captures the downside risk of policy alternatives, (iii) provides visual outputs for dissemination and communication of uncertainty and decision risk, and (iv) includes instructions on how to use the toolkit, standard text descriptions and examples for each component. The use of the toolkit is demonstrated through a hypothetical example.
ConclusionThe Decision Uncertainty Toolkit improves existing methods for communicating infectious disease model results by providing additional information regarding uncertainty and decision risk associated with policy alternatives. This empowers decision-makers to consider and evaluate decision risk more effectively when making policy decisions. Improved understanding of decision risk can improve outcomes in future public health crises.

While mental health literacy is an important component to successful help-seeking, rural populations often face gaps in both knowledge and service provision. Informed by the Theory of Planned Behaviour and Self-Efficacy Theory, we designed the ‘Skills for Resilience’ as a brief, once-off, community-based educational intervention to increase Irish farmers’ mental health literacy and help-seeking intentions. We adopted a quasi-experimental between (group: intervention and control) and within-group design (time: baseline [T1], immediately post-intervention [T2], and ≥ 1 month post-intervention [T3]). A total of 72 participants (intervention n = 37; control n = 35) were recruited from knowledge-sharing discussion groups. Although recruitment was also open to women, all discussion groups consisted of men. A trained facilitator delivered a discussion lasting between 30 and 90 minutes. Five intervention participants also participated in a qualitative interview after T3. Our results identified intervention participants’ mental health literacy increased significantly at T2 and T3 compared to T1, but did not increase between T2 and T3. Mental health literacy was also significantly greater in the intervention group compared to the control group at T2 and T3. Help-seeking intentions and self-efficacy in seeking mental healthcare also increased significantly at T2 compared to T1, but did not increase between T1 and T3 or T2 and T3. There were no significant changes in outcome measures for the control group at any time point. Through reflexive thematic analysis we identified that the intervention also addressed stigma against mental health (Theme 1) and provided important resources for participants and their community’s present and future coping (Theme 2). At T3, 100% of participants enjoyed the discussion and would recommend the intervention to other farmers. This intervention provides a successful example of integrating the Theory of Planned Behaviour and Self-Efficacy Theory to improve mental health literacy in farmers using a brief, educational intervention.by Andrea C.

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 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).

We examined the associations of midlife and old-age cardiovascular risk factors, education, and midlife dementia risk scores with cognition at 90 + years, using data from a population-based study with 48 years of follow-up. Participants were 96 individuals aged 90–97 from the older Finnish Twin Cohort study. Individual cardiovascular risk factors assessed via questionnaires in 1975, 1981, 1990, and 2021–2023 included blood pressure, body mass index, physical activity, and cholesterol, and self-reported educational attainment. The Cardiovascular Risk Factors, Aging, and Dementia (CAIDE) score and an educational-occupational attainment score were used as midlife dementia risk scores. Cognitive assessments included semantic fluency, immediate and delayed recall from a 10-word list learning task, and a composite cognitive score. Regression analyses were conducted with dementia risk factors predicting cognition at 90 + years, adjusting for age, sex, education, follow-up time, and apolipoprotein E genotype (ε4-carrier vs non-carriers). Results showed that higher education and higher educational-occupational score were associated with better cognitive performance in all cognitive measures. Those with high midlife blood pressure scored significantly higher in all cognitive tests than those with normal blood pressure. Conversely, those with high old-age blood pressure scored lower in semantic fluency and composite cognitive score, but not in immediate or delayed recall. Other cardiovascular risk factors and the CAIDE score did not show consistent associations with cognition. Education appears to have a long-lasting protective effect in cognitive aging, whereas midlife and old-age cardiovascular risk factors were not significantly associated with cognition at 90 + years.by Mireia Solé Pi, Luz A.

A long-standing question in the study of quantity discrimination is what stimulus properties are controlling choice. While some species have been found to do it based on the total amount of stimuli and without using numerical information, others prefer numeric rather than any continuous magnitude. Here, we tested cats, dogs, and humans using a simple two-way spontaneous choice paradigm (involving food for the first two, images for the latter) to see whether numerosity or total surface area has a greater influence on their decision. We found that cats showed preference for the larger amount of food when the ratio between the stimuli was 0.5, but not when it was 0.67; dogs did not differentiate between stimuli presenting the two options (smaller vs. larger amount of food) regardless of the ratio between them, but humans did so almost perfectly. When faced with two stimuli of the same area but different shapes, dogs and humans exhibited a preference for certain shapes, particularly the circle, while cats’ choices seemed to be at chance level. Furthermore, cats’ and dogs’ reaction times were equal across conditions, while humans were quicker when choosing between stimuli in trials where the shape was the same, but the surface area was different, and even more so when asked to choose between two differently sized circle shapes. Results suggest that there is no universal rule regarding how to process quantity, but rather that quantity estimation seems to be tied to the ecological context of each species. Future work should focus on testing quantity estimation in different contexts and different sources of motivation.by Rahil Mahmoudi, Maral Nabaee, Akram Kooshki, Saba Shourideh Yazdi, Mahboubeh Neamatshahi, Elaheh Foroumandi
BackgroundWith the high prevalence of diabetes worldwide and the known benefits of functional foods in controlling diabetes, this study aimed to explore the connection between prebiotic food intake and biochemical indices in diabetic patients.
MethodsThis cross-sectional study was conducted on 504 participants with type 2 diabetes who were part of the Sabzevar Persian Cohort study that was initiated in February 2018. A 148-items food frequency questionnaire was utilized to assess the daily amount of prebiotic food consumption. Blood serum samples were collected from participants to measure fasting blood sugar levels, lipid profile, and kidney function indicators. Additionally, anthropometric measurements were taken following standard protocols. Statistical analyses were performed using SPSS version 20, with correlation tests adjusted for confounders, and significance set at p Results
This study involved 44.9% male and 55.1% female participants, with an average age of 54.81 ± 7.65 years. A significant correlation was observed between soybean consumption and serum low density lipoprotein (LDL) status (R = −0.110, P = 0.014). Moreover, a higher intake of banana was linked to lower blood urea nitrogen (BUN) levels (R = −0.109, P = 0.015). Furthermore, the consumption of honey exhibited a negative association with both systolic blood pressure (BP) (R = −0.106, P = 0.018) and diastolic BP (R = −0.132, P = 0.003). Green peas intake was also inversely associated with DBP (R = −0.092, P = 0.039).
ConclusionThis study found a positive correlation between the regular intake of prebiotic foods and improved management of BUN, LDL, and BP in individuals with type 2 diabetes. However, further mechanistic studies are necessary to better understand the potential causal effects of prebiotic foods on metabolic health in this population.
