BackgroundZika virus (ZIKV) infection has been inconsistently associated with neurodevelopmental delay (ND). We aimed to compare the incidence of ND between ZIKV-exposed and ZIKV-unexposed children within the ZIKAlliance (ZA) cohort, in Colombia, assessed 2 years after birth (2018–2021).
MethodsWe performed a neurodevelopmental evaluation on normocephalic children (aged 40–72 months) from the ZIKAlliance cohort. Children were classified as ZIKV-exposed (maternal positive RT-qPCR or virus neutralization test – VNT) or unexposed (maternal negative IgG ELISA or VNT in paired antenatal samples). A trained psychologist, blinded to exposure status, administered the Denver Developmental Screening Test II (DDST-II). Children were considered at ND risk if they presented ≥1 delay or ≥2 cautions in one or more areas, within their age range in the DDST-II scale. Inconclusive initial tests were re-evaluated. Adjusted odds ratios were estimated using logistic regression.
ResultsWe analyzed conclusive DDST-II results from 153 children (mean age: 4.7 years; 53.8% male). Overall, 57.2% (n = 83) were classified as cases of ND. Children with ND were more likely to be male (61.4% versus 43.5%) and less likely to attend daycare or school (42.2% versus 11.3%) than children with normal development. After adjusting for child age, sex, household size, and education, the association between in utero ZIKV exposure and ND was not statistically significant (OR = 0.71; 95% CI: 0.32–1.59, p = 0.320). However, children attending daycare or school had a significantly lower risk of ND compared to those who stayed at home.
ConclusionsPrenatal ZIKV exposure was not associated with ND in this cohort of normocephalic preschool children. Instead, attending a community daycare or school emerged as a significant protective factor against developmental delays.

Mosquito-borne arboviruses pose a growing public health concern in Canada, particularly in the context of climate change and increased global travel. This study aimed to quantify the burden of endemic and non-endemic mosquito-transmitted arboviral diseases in Canada by examining hospitalization trends from 2002 to 2023. Using administrative hospital data from the Canadian Institute for Health Information (CIHI) and national West Nile virus (WNV) surveillance data, we analyzed patient demographics, temporal and spatial patterns, and disease classification. Hospitalizations were classified as endemic (e.g., WNV) or non-endemic (e.g., dengue, chikungunya, Zika, yellow fever) based on historical presence and vector establishment in Canada. A total of 2,470 unique hospitalizations were identified, with 56.4% attributed to endemic diseases and 39.7% to non-endemic diseases. WNV accounted for over 99% of endemic-related hospitalizations, with peaks in 2003, 2007, and 2012 aligning with national surveillance data. Hospitalizations were highest among males aged 75–79 years, particularly in the southern regions of Saskatchewan, Manitoba, and Ontario. Non-endemic disease hospitalizations, primarily due to dengue and chikungunya, increased after 2010 and were more evenly distributed throughout the year, reflecting travel patterns. Younger adults (20–49 years) were most affected. The study highlights limitations in diagnostic coding and surveillance coverage, particularly the exclusion of Quebec data and underreporting of emerging arboviruses. These findings underscore the utility of hospital administrative data in complementing traditional surveillance systems and identifying populations at risk for severe outcomes. As climate change and travel continue to influence arboviral disease dynamics, integrated data sources are essential for guiding public health planning and response.

This study evaluated the effects of increasing narasin doses on ruminal fermentation, nutrient digestibility, ruminal pH stability, papillae histology, and microbial composition in Angus cattle fed feedlot diets. Three rumen-cannulated Angus steers (average body weight: 680 kg) were assigned to a 3 × 3 Latin square design and received diets containing 13, 20, or 27-ppm of narasin. Each experimental period consisted of 14 days of adaptation followed by seven days of sampling. Ruminal degradability was assessed on days 15–17, apparent digestibility on days 15–19, continuous ruminal pH on days 19–20, and samples for short-chain fatty acids (SCFA), microbiota, and ruminal histology were collected on days 20 and 21. Ruminal degradability was not affected by narasin dose. Digestibility of acid detergent fiber (ADF) was significantly influenced, with the greatest values observed at 27-ppm (P = 0.01). Increasing narasin doses improved ruminal pH stability, as indicated by a linear increase in minimum pH (P = 0.01) and a reduction in the duration of pH below 5.6 (P = 0.10). At 13 ppm, SCFA production, particularly acetate and propionate, increased (P P P = 0.02), and butyrate (P P P = 0.03). Narasin supplementation altered ruminal microbial composition, increasing the relative abundance of Lachnospiraceae and Isotricha while reducing lactic acid–producing bacteria. In terms of ruminal morphology, supplementation with 20-ppm of narasin increased the keratin layer thickness of ruminal papillae (P = 0.02), suggesting enhanced epithelial development. Overall, narasin supplementation modulated ruminal function and microbial ecology, with doses between 13 and 20-ppm providing the most favorable balance between fermentative efficiency and ruminal health in feedlot cattle.

Cadmium (Cd), a toxic heavy metal found in agricultural landscapes worldwide, has been pointed out in cropped soils with Theobroma cacao L., as one of the main contaminants that translocate into plant tissues. Among the factors linked to cadmium translocation into plants, the role of soil bacterial communities in chemical transformation in soils has been poorly investigated. Overall, soil bacterial communities are shaped by diverse environmental and anthropogenic factors that influence crop yield and health. Cadmium alters soil microbial communities and increases the risk to human health through plant uptake. Although the impacts of cadmium on soil bacteria have been studied in other crops, there is limited information on cacao. Thus, this study aimed to assess the responses of soil bacterial communities in cacao farms to cadmium exposure, both natural and spiked. A total of 225 rhizosphere soil samples were collected from 16 plots across five cacao farms in two Colombian departments. The complementary approaches used were: (i) 16S rDNA amplicon sequencing to assess the composition of the bacterial community in soils with natural Cd concentrations, and (ii) isothermal microcalorimetry (IMC) to measure the temporal metabolic responses of bacteria to Cd in closed systems for 80 hours at 25 °C. The findings suggest that nearly 28% of the bacterial community responds to high cadmium concentrations in soils, both in natural and experimental conditions. Field-based observations revealed that Cd-responsive taxa detected under natural soil conditions included several unculturable bacterial groups, whereas laboratory experiments with Cd spiking predominantly selected for previously characterized cadmium-tolerant bacteria (CdtB). Significant variation in natural Cd-bacterial community composition and Cd-related metabolic activity was observed across the farms. Moreover, Cd-responsive bacterial taxa exhibited increased abundance during Cd spikes. As expected, contrasting patterns were revealed by the activity-response measured by IMC and taxonomic analyses of 16S rRNA gene sequences.

IntroductionGlobally, the COVID-19 pandemic significantly impacted the provision of maternal health services, especially facility-based delivery. However, there is little evidence on the proportion of women who delivered at the health facility in various locations and the factors that influenced women’s decision-making in choosing a place of delivery during and amid the COVID-19 restrictions. Therefore, this study assessed the prevalence and factors associated with health facility delivery during the COVID-19 pandemic in the Tamale Metropolis of Ghana.
MethodsAn analytical cross-sectional study design was conducted. A multistage sampling technique was used in selecting the study communities. At the individual level, random sampling technique was applied, and 461 women were recruited from 21st February 2021–21st March 2021. Using a questionnaire, a face-to-face approach was used to conduct the interviews. The questionnaire included questions on socio-demographic characteristics, place of childbirth and factors that led to the choice of delivery place. Using Statistical Package for Social Sciences version 25, descriptive and binary logistic regression analysis were conducted.
ResultsThe results revealed that 64.0% of the women delivered in health facilities during the pandemic. Health facility delivery was more likely to occur among women with higher educational status (AOR: 5.2; 95% CI: 1.40–19.40), married women (AOR:6.3; 95% C.I:1.10–35.80), active National Health Insurance Scheme holders during delivery (AOR: 13.8; 95% C.I: 4.60–41.90), women who received education on birth preparedness and complication readiness (AOR: 7.6; 95% C.I:3.30–17.50) and women with underlying conditions before pregnancy (AOR:3.3; 95% C.I:1.20–9.20). There were reduced odds of health facility delivery among women with a history of home delivery (AOR:0.2; 95% C.I:0.10–0.50), when the mother-in-law decides on the place of delivery (AOR:0.1; 95% C.I:0.03–0.50), longer distance to the place of delivery (AOR:0.3; 95% C.I:0.01–1.00) and when women perceived COVID-19 as a barrier to facility delivery (AOR:0.1; 95% C.I:0.03–0.20).
ConclusionOur findings show that health facility delivery declined during COVID-19. Factors that affected health facility delivery were educational status, marriage, having an active National Health Insurance Scheme, education on birth preparedness and complication readiness, underlying conditions before pregnancy, history of home delivery, mother-in-law decision on place of delivery, distance to place of delivery and perceiving COVID-19 as a barrier to facility delivery. These contributed to low facility delivery. Thus, maternal health services need to be brought to the doorsteps of communities, including proper implementation of the Focused Antenatal Care and community-based pregnancy school programmes, especially during future pandemics.

Reprogramming of energy metabolism is one of the hallmarks of cancer cells and mutations that modify wild type intestinal cells to colon carcinomas increases cellular energy expenditure. Mitochondria are the main site for ATP production in (cancer) cells and disrupting their function results in impaired tumor forming efficacy. The mitochondrial ribosomal proteins (MRPs) constitute the ribosome specifically in mitochondria, and as such are crucial for the translation process of the electron transport chain complex subunits. We hence aimed to explore the consequence of reduced MRP expression on adenomagensis and investigate this in a genetic mouse model with bodywide heterozygosity for Mrpl54. We show that Mrpl54 heterozygosity does not alter adenoma formation, intestinal proliferation or apoptosis in a heterozygous Apc model. Furthermore, diminished Mrpl54 expression did not decrease stemness or global parameters of metabolism in colorectal cancer cell lines.

Coffee is the most common drink in the world, second only to water. This makes caffeine, the ingredient of coffee known for its wakefulness-promoting effects, one of the most used psychoactive substances. The psychoactive property of caffeine is well-characterized, and entails its interaction with the adenosine receptors, involved in sleep regulation. While studies have shown a deleterious immediate effect of caffeine on sleep, less is known about the effects of chronic caffeine exposure. In the present cross-sectional study, we investigated this relationship across a large cohort of 30,154 individuals participating in the Swedish Cardiopulmonary Bioimage Study (SCAPIS), which allowed us to compare habitual coffee intake with sleep habits, subjective estimate of daytime sleepiness, and underlying genetic variants. According to our analyses, different degrees of coffee consumption, confirmed by statistical association with previously reported genetic variants, showed very low association with estimated patterns of sleep habits or perceived daytime sleepiness. These results indicate that coffee may be less impactful on sleep habits than previously thought, or that other mechanisms, such as the adaptive capabilities of the adenosine system in adult coffee users, may dampen its psychoactive potency.

BackgroundChronic pain affects up to 60% of people with chronic kidney disease (CKD), yet remains under-recognised and under-treated. Pain management in this population is complicated by altered drug pharmacokinetics, polypharmacy, and the potential nephrotoxicity of conventional analgesics. Despite the high prevalence and significant impact on quality of life, evidence-based guidance specific to pain management in CKD remains limited.
ObjectivesThis systematic review aims to evaluate the effectiveness and safety of both pharmacological and non-pharmacological interventions in reducing chronic pain intensity among people with CKD on dialysis, not on dialysis, and kidney transplant recipients, across all stages of CKD.
MethodsThe primary outcome is the effectiveness of interventions in reducing chronic pain intensity as assessed by pain assessment tools. We will conduct a comprehensive search of MEDLINE, Embase, CINAHL, Web of Science, and ClinicalTrials.gov from their inception to the present date to identify studies for chronic pain management in people living with CKD. Study screening will be conducted independently by two reviewers. One reviewer will extract data from each study, with a second reviewer cross-checking for accuracy and completeness. Data will be extracted on study characteristics, participant demographics, intervention components, pain outcomes, and adverse events. The certainty of evidence will be evaluated independently by two reviewers using the GRADE approach. Where applicable, data will be combined in meta-analyses using random-effects models. Additionally, a network meta-analysis will be performed if enough studies are available.
Expected resultsThis review will synthesise the current evidence for pain management strategies in CKD, by evaluating effectiveness of interventions among people receiving different renal replacement therapy modalities with varying pain and disease phenotypes. Findings will highlight the comparative effectiveness of various interventions while considering their safety profiles specific to the CKD context. The review will identify gaps in the literature and provide recommendations for clinical practice and future research.
SignificanceThis review seeks to deliver a thorough evaluation of pain management strategies for people living with CKD. This systematic review is supported by the UK Kidney Association (UKKA), and findings will inform the upcoming UKKA guideline on symptoms management in people with CKD, alongside the other symptoms including itch, fatigue, and gastrointestinal symptoms. This review will aid clinicians in making well-informed decisions regarding pain management strategies, ensuring a balance between effectiveness and the specific risks associated with CKD.

Urban soundscapes, particularly those experienced in green spaces, have been increasingly recognized as factors that influence human mental health. This scoping review explores the existing literature on soundscapes within urban green spaces and their associated mental health outcomes. It aims to classify the methodologies used in this domain, identify mental health outcomes related to urban green space soundscapes, and examine specific soundscape elements and their correlations with mental health. A systematic search of peer-reviewed studies was conducted. After screening titles, abstracts, and full texts, 22 studies met the inclusion criteria. Diverse methodological approaches were identified, with an emphasis on quantitative multi-method designs. Commonly studied mental health outcomes include stress reduction, mood enhancement, perceived restorativeness, and cognitive restoration. Standardized psychometric tools, such as the Perceived Stress Scale (PSS-14), Positive and Negative Affect Schedule (PANAS) and Perceived Restorativeness Soundscape Scale (PRSS) are frequently used as outcome measures. Natural soundscape elements such as birdsong, water sounds, and rustling leaves had a positive association with relaxation and perceived mental restoration throughout all studies, while mechanical sounds, such as traffic noise were linked to adverse mental health outcomes. These findings highlight that natural soundscapes in urban green spaces have a potential positive relationship with mental health by reducing stress and enhancing mood. However, the cross-sectional design and methodological heterogeneity of the included studies limit causal interpretation. Future research should explore multi-sensory experiences and examine soundscapes in diverse urban contexts to provide more robust insights into their relationship with mental health. The practical implications suggest that urban planners should prioritize integrating natural sound elements into urban areas to improve mental health. The study protocol of this scoping review had been registered at OSF (osf.io/4r7gd).

BackgroundThe National Institute for Health and Care Research accepts applications for pilot and feasibility studies to their Research for Patient Benefit (RfPB) programme. There has been limited work describing the design practices of these applications and funding status. Knowing some of the qualities which may contribute towards a pilot or feasibility study application successfully gaining funding could help researchers improve the quality of their applications. Therefore, this study describes the protocol for a review looking at the characteristics of funded and non-funded external pilot trial applications. In particular, the primary objective is to describe the planned sample size and sample size justifications.
MethodsThe study will be conducted on 100 applications from Competition 31–37 with a randomised feasibility design, identified and given access to us by RfPB where the lead applicant has consented. We will screen these applications to identify the external pilot trials, first looking through the titles and then the full text. Following this, we will extract data on information such as medical area, study design, objective(s), sample size, sample size justification, and funding outcome stage one and two. Validation will be performed on 20% of the data extracted; discrepancies will be resolved by discussion or a third reviewer will decide if there is no consensus. We will use descriptive statistics to summarise quantitative data, and will analyse qualitative data using thematic analysis. Findings will be summarised through discussion with the project contributors to produce a reader-friendly guidance document.
DiscussionThis work will provide a more complete picture of RfPB external randomised pilot and feasibility trials. The findings will assist researchers when planning their pilot trials, and could help improve the quality of submitted applications.

BackgroundThe demographic landscape of Western countries has shifted to a more diverse one. Along with the trend of an aging population, a new problem has emerged, which is the increased linguistic diversity in the aging population in these countries. As people age and their care needs increase, they may not receive optimal care if they don’t speak the same language as their caregivers in long-term care facilities. Culturally and linguistically responsive long-term care services are important to ensure the best care for an aging population, but there is limited evidence in the literature on the scope and practice of these services. The objective of this scoping review is to map out the types of CLR programs in LTC settings and examine their core components and target populations.
MethodsThe Arksey and O’Malley framework, further developed by Levac and colleagues, will be employed in this scoping review. The research question was framed using the PCC framework. A comprehensive systematic search was developed with an experienced librarian and will be conducted in Scopus, CINAHL, Embase, Medline, PsycINFO, and Academic Search Complete. All primary study designs, including quantitative, qualitative, and mixed methods, will be included. Studies must focus on culturally and linguistically responsive care programs used or implemented in long-term care services. There will be no date or language limitations. Findings will be thematically synthesized to answer the research question.
ConclusionThis review protocol provides a transparent process for how it will be conducted. We aim to contribute to a better understanding of what culturally and linguistically responsive care programs exist, how cultural and linguistic responsiveness is currently addressed across diverse care environments, and what gaps remain in long-term care.

High-intensity interval training (HIIT) is an effective intervention for improving metabolic health and mitigating metabolic dysfunction-associated steatotic liver disease (MASLD). Nonetheless, the stability of these benefits throughout detraining periods and upon weight regain remains inadequately characterized. This study aimed to evaluate whether hepatic improvements induced by HIIT are sustained during detraining, even after body weight regain. Eighty male C57BL/6 mice were fed either a control (10% fat) or a high-fat (HF) diet (50% fat) for 12 weeks. Following this period, the animals were allocated to groups subjected to continuous HIIT or intermittent training cycles (each lasting 3 weeks). The outcomes assessed included body mass (BM), glucose tolerance, lipid profiles, liver enzyme levels (aspartate aminotransferase and alanine aminotransferase), hepatic steatosis, and the expression profiles of genes associated with lipogenesis (Srebf1, Mlxpl, and Fas), β-oxidation (Ppara and Cpt1a), and endoplasmic reticulum (ER) stress (Atf4, Ddit3, and Gadd45). Compared with the sedentary HF-NT condition, continuous HIIT reduced BM and improved glucose tolerance. Intermittent training (HF-TNT, HF-NTN) preserved metabolic benefits and reduced triglyceride and cholesterol levels. Notably, hepatic steatosis was significantly alleviated in all training groups but persisted even after detraining. Additionally, HIIT downregulated the expression of lipogenic genes and upregulated the expression of genes involved in β-oxidation. The levels of markers indicating ER stress were attenuated by HIIT, with a sustained reduction during periods of detraining. HIIT-induced metabolic and hepatic improvements persist partially during detraining, despite weight regain. These findings underscore the therapeutic value of continued or periodically repeated physical training in mitigating the adverse effects of an HF diet and preventing the progression of metabolic disorders such as MASLD.

BackgroundParenting responsibilities can be particularly challenging for patients receiving mental health services, often resulting in a range of negative impacts on children. Incorporating a family-focused approach into the usual care of parents with mental illness has been recommended to promote patient recovery while supporting the well-being of children and the entire family unit. This study aimed to document the family-focused practices undertaken by psychiatrists working with parents who have a mental illness and to explore potential facilitators and barriers to these practices.
MethodsA sequential explanatory mixed-method design was used, combining an online survey and individual interviews. Family-focused practices were reported by 27 psychiatrists through the French version of the Family-Focused Mental Health Practice Questionnaire. Follow-up qualitative individual interviews were conducted with 5 psychiatrists. Item-by-item analysis of the quantitative data was performed, followed by a thematic analysis of the qualitative data, integrating findings from both sources.
ResultsAlthough psychiatrists acknowledge their patients’ parenting role, most are reluctant to provide further support. Key barriers to family-focused practice include the predominantly individual-focused nature of psychiatric care, stigma, consent issues, and limited collaboration between adult and child services. Facilitators include psychiatrists’ professional autonomy, personal experience, and confidence in conducting family meetings.
ConclusionPsychiatrists can play a pivotal role in identifying, acknowledging, and providing appropriate support to parents with mental illness and their families, including children. Developing comprehensive guidelines and targeted training is essential to equip psychiatrists with effective strategies for addressing parenting challenges in patients with complex mental health issues. Additionally, psychoeducational resources for children should be incorporated. Implementing these initiatives may lead to more compassionate, targeted care and improved outcomes for parents and their families.

The San Clemente Island fox (Urocyon littoralis clementae) is classified as a focal species for conservation management by the US Navy. They are considered vulnerable to a variety of vector-borne diseases due to their relatively high population density and low genetic diversity. During the dry (July–November) and wet (December–February) seasons of 2017–2018 we live-trapped 95 foxes and collected ectoparasites to test for the presence of pathogens. We found a significant difference in ectoparasite abundance on foxes between seasons, but no differences associated with sex or age. We found that foxes carried two species of flea (Echidnophaga gallinacea and Orchopeas howardi) and two tick species (Ixodes pacificus and Ixodes jellisoni). No evidence of Borrelia burgdorferi, Anaplasma phagocytophilum, or Borrelia miyamotoi bacteria were found. This paper is the first account of ectoparasite species identification, quantification, and pathogen testing for the San Clemente Island fox subspecies.

As cancer survival rates increase in Canada, a growing number of working-age individuals face challenges returning to work after treatment. This study examines the experiences of Canadian cancer survivors who remained in or returned to the workforce during the COVID-19 pandemic. Participants were cancer survivors aged 25−62 who had been employed prior to their diagnosis. They completed a brief online survey about their return-to-work (RTW) experiences and were invited to participate in a semi-structured interview. Seven participants took part in the interviews, which were transcribed and analyzed through inductive thematic analysis. Four overarching themes emerged: (1) The Perfect Storm of Systemic Challenges, highlighting healthcare barriers exacerbated by the pandemic; (2) You Are Not Alone, emphasizing the importance of social support in mitigating isolation; (3) One Size Does Not Fit All – Individual Journeys, reflecting the need for flexible workplace accommodations and patient self-advocacy; and (4) Creating a “New Normal,” illustrating how survivors reassessed priorities, work identities, and personal well-being. Participants described delayed treatments, lack of fertility options, and limited support during appointments due to pandemic restrictions. Workplace accommodations varied, with some survivors feeling supported while others faced inflexibility. Findings emphasized the need for improved healthcare responsiveness, personalized RTW accommodations, and improved employer training to support cancer survivors. The study also reveals how the COVID-19 pandemic exacerbated existing systemic gaps, underscoring the importance of preparing healthcare and employment systems to better support vulnerable populations during times of crisis.

The growing popularity of virtual reality (VR) applications has been reflected in numerous studies, particularly those examining the effects of VR on the human body, physical activity, and sports training. Comparative research suggests that simulated environments can influence physiological and psychological responses in distinct ways. The integration of VR with electromyographic (EMG) systems opens new opportunities to study biofeedback and muscle activation during exercise in real-time. However, only a limited number of studies have provided quantitative data on muscle fatigue. In the present research eight healthy male participants from previously described studies were examined using a VR environment to explore muscle fatigue. EMG signals were recorded from three muscle groups, and knee flexion angles were monitored. A VR simulation developed in Unreal Engine 5 was designed to reproduce a natural river scene for rowing training. The Discrete Wavelet Transform (DWT) was applied to both previously collected and VR-based data, calculating median frequency (MDF) distributions and linear regression for lower extremity muscles. Wilcoxon signed-rank tests comparing VR and non-VR conditions for the measured muscles: the Rectus Femoris, Biceps Femoris, and Gastrocnemius Lateralis, did not reveal statistically significant differences (all p > 0.05). Although no significant differences were observed, the proposed methodology introduces a valuable framework for quantitative fatigue assessment. By integrating VR with EMG analysis, this approach provides new perspectives for investigating muscle fatigue and its modulation in immersive environments.

BackgroundAccess to primary care is an important component of health systems. Given the barriers experienced by unattached patients to accessing primary care in Quebec (Canada), the Ministry of Health mandated the province-wide implementation of Primary care access points for unattached patients (Guichet d’accès première ligne; GAP), an organizational innovation designed to orient patients to the most appropriate professional or service. This study aims to 1) document the factors associated with unmet healthcare needs after receiving GAP services and 2) assess whether those factors vary by GAP orientation.
MethodsThis cross-sectional study builds on data collected between April and July 2024 using an online patient questionnaire. All patients with a valid email address registered on the centralized waiting list for unattached patients in three local health territories (LHTs) received an email invitation to participate in the survey. The total sample included 20,282 participants who responded to the questionnaire and used the GAP.
ResultsThe findings showed that younger age, self-reporting poor/fair physical and mental health, receiving services in LHT 3 and reporting an emergency room visit were associated with increased likelihood of reporting unmet needs. Stratified analyses suggested that some characteristics (age, use of emergency room) were associated with unmet needs across orientations, while others (self-reported physical and mental health) were associated with specific orientations.
ConclusionThis study serves as a first step in deepening our understanding from a patient perspective of how to better plan primary care services and improve unattached patients’ experiences using the GAP. The findings showed that patients oriented to other professionals than a medical appointment with a family physician had the highest percentage of unmet needs. The next step involves an in-depth exploration of the reasons for patients’ unmet needs, enabling the development of more precise and effective strategies to address them.

The attentional system tends to prioritize negative stimuli in the early stages of processing, favoring threat detection. However, it is unclear whether this bias is maintained or reversed toward positive stimuli at later stages. In this study, we used a free-viewing paradigm with eye tracking to examine early and late attentional biases toward negative, positive, and neutral stimuli (humans in emotionally unloaded activities) versus control stimuli (inanimate objects) in 122 participants without affective disorders (64 men, 58 women). We fitted generalized linear mixed models with random intercepts for stimuli and random intercepts and slopes for participants, and used non-parametric bootstrap resampling to obtain robust estimates and confidence intervals. Additionally, the number of first fixations was analyzed with a COM-Poisson. Results showed that participants fixated faster (χ2(3) = 97.55, p 2(3) = 337.45, p χ2(3) = 200.24, p χ2(3) = 207.02, p

IntroductionMental health problems constitute a significant global health challenge due to their rising prevalence and substantial treatment gap. Digital Mental Health Interventions (DMHIs) including mental health chatbots have emerged as promising solutions due to their effectiveness and scalability. Recent advances in Generative Artificial Intelligence (GenAI) have improved the conversational abilities of these chatbots, further amplifying their potential. However, despite instances of inadvertent harm stemming from the unpredictable nature of GenAI, little attention has been paid to user experience and safety of these chatbots.
ObjectiveThis proposed review will explore existing research on GenAI-based mental health chatbots. Specifically, it aims to identify and describe current chatbots, focusing on user experience, safety and risk mitigation strategies.
MethodsThe review will follow the Joanna Briggs Institute (JBI) guidelines for conducting scoping reviews. It will also adhere to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Review (PRISMA-ScR). A systematic database search of Medline (PubMed), Scopus, PsycINFO, ACM Digital Library, and IEEE Xplore will be conducted. The database search will be complimented by research-based search engines (Google Scholar and Consensus). Studies focusing on the development, evaluation or implementation of GenAI-based mental health chatbots will be included without limitations to specific disorders or population groups. Two independent reviewers will perform screening and data extraction. The analysis will include descriptive summary and thematic analysis, with results presented in tabular, graphical, and narrative formats.
ConclusionThis review will provide a comprehensive overview of GenAI-based mental health chatbots while identifying innovative practices and knowledge gaps relating to user experience and safety. Findings will inform the ethical development, evaluation and implementation of GenAI-based mental health interventions.

BackgroundPlacebo and nocebo effects significantly influence health outcomes, yet healthcare professionals receive limited training and guidance on their mechanisms and clinical application, creating a gap in education and practical understanding. Conducted within the European PANACEA Consortium, this study evaluated healthcare professionals’ knowledge, attitudes, and practices regarding placebo and nocebo effects, and assessed their needs in further education.
MethodsAn online cross-sectional survey among a European multi-country convenience sample of healthcare professionals collected data assessing participants’ knowledge, perceptions, and experiences regarding placebo and nocebo effects; their application and ethical considerations in clinical practice; and investigated educational needs and interest in further training. Quantitative data were analyzed using descriptive statistics, and thematic analysis was applied to the free-text responses.
ResultsAmongst 807 participants, 71.7% reported taking advantage of placebo effects in their practice, and over half of participants (55.8%) observing nocebo effects. Participants reported feeling somewhat confident (53.3%) in harnessing placebo effects with 47.5% feeling confident in preventing nocebo effects. The majority of respondents had not received formal training on placebo and nocebo effects, with most expressing an interest in further training in areas such as healthcare education, emphasizing communication skills to enhance placebo effects, and knowledge to recognize and reduce nocebo effects.
ConclusionsThere is a significant need for more comprehensive training on placebo and nocebo effects, particularly in early health professional education. These findings informed the development of educational resources and best practice recommendations developed as part of the outcomes from the PANACEA Consortium, improving the understanding and application of these effects among healthcare professionals across Europe.
