Providing peer support can benefit youth peer support workers (peers)et by supporting self-determination, recovery and resilience to self-stigma. There is a need to clarify the role of the organisation in providing benefits for peers. We aimed to identify the organisational contexts and mechanisms that result in the creation of healthy workplaces for peers.
Rapid realist review guided by the Realist and Meta-Narrative Evidence Syntheses–Evolving Standards guidelines and Pawson’s iterative approach.
MEDLINE, CINAHL, PsycINFO, ERIC, SocINDEX, Google Scholar and Embase were searched from 1979 to 2025.
We included qualitative and quantitative peer-reviewed studies and grey literature that captured characteristics of organisational practices and employment considerations in youth peer support programmes.
Articles were screened independently by multiple reviewers. Inclusion criteria were adjusted to capture literature on organisational practices, and employment considerations for youth peer support programmes. Data were extracted and analysed retroductively to develop Context-Mechanism-Outcome Configurations (CMOCs).
Five employment-related risks to peer well-being were identified: (1) difficulty entering the job market, (2) lack of role clarity, (3) pressure to live up to ideals, (4) retraumatisation and (5) stigma. Six CMOCs were developed; all focused on the creation of equitable employment and supporting peer development and empowerment were developed.
Community-based mental health organisations can facilitate equitable peer employment through strategies that reduce professional stigma, enhance peer resilience and promote professional and personal development. Policy reform that addresses precarious work conditions is needed to support healthy work environments.
This scoping review protocol aims to examine the role of the Internal Regulation Core (IRC) as an intra-hospital governance structure that coordinates capacity and patient flow and may function as a strategic hub for disruptive innovation in hospital management. By integrating organisational routines, rules and, when available, enabling technologies, IRCs may strengthen operational efficiency and contribute to higher-quality care delivery. As hospitals face increasing operational complexity and constrained resources, clarifying what IRCs are, how they are implemented across settings, and what innovations and impacts are reported has become a priority.
This scoping review will follow the Joanna Briggs Institute guidance and Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. A comprehensive search will be conducted across five databases (MEDLINE/PubMed, Embase, Scopus, Web of Science and LILACS) and grey literature sources, without language or date restrictions. The searches were conducted up to 6 July 2025. Two reviewers will independently screen studies and extract data using a standardised form; disagreements will be resolved by consensus or a third reviewer. Findings will be synthesised descriptively and thematically, with results presented in tables and narrative summaries, including innovation streams.

To optimize fitness when facing predation, animals perform threat-sensitive predator avoidance whereby they match the magnitude of the antipredator response to the severity of the perceived threat. Injury-released chemical alarm cues are a reliable indicator of predation risk in aquatic organisms, triggering overt antipredator responses upon detection by conspecifics. Animals with threat sensitivity typically have graded responses to increasing concentrations of these cues which plateau when a maximal response is reached, however, this is undocumented in crayfish. Furthermore, most research currently uses alarm cue exposures consisting of one crushed crayfish diluted in 100–400 mL of water, while it could be ecologically relevant for them to respond to lower concentrations, especially given that predation events can consist of bites or lacerations which would release less alarm cues. The quantity of cue administered into the tank (exposure concentration) is also highly variable, making experimental comparisons difficult. In our study, we collected crayfish alarm cues by rinsing five cut sites (to mimic laceration wounds) and diluting the cues in 100 mL to 100 L of water. Over two experiments, we determined the antipredator response of crayfish exposed to one of five alarm cue concentrations or a water control. During these trials, 20 mL of the cues were administered into 10 L of water, thereby standardizing the test subject’s exposure to the cues. While we failed to find evidence of graded responses, we discovered that alarm cues elicited overt antipredator behaviour when diluted in up to 10 L of water, but this response was lost when cues were diluted in 100 L. Furthermore, this study is the first to successfully use frozen-thawed alarm cues in crayfish. These findings can help direct future research, providing information on the ecologically relevant range of chemical cues and improving welfare by reducing lab-animal sacrifice.by Martina Ferrari-Díaz, Ashuin Kammar-García, Juan Silva-Pereyra, Carmen García-Peña
Cognitive reserve (CR) refers to the adaptation of cognitive performance to endure brain pathology or the aging process. CR can be categorized into static (education and occupation) or dynamic (leisure and physical activities) proxies. Typically, longitudinal studies assess CR as a composite score at baseline and cognitive performance as a global score. This study aimed to compare the relationship between different CR proxies (static and dynamic) with 9-year domain-specific cognitive trajectories, and the risk of cognitive impairment in older adults. Data from the latest four waves of the Mexican Health and Aging Study (MHAS; n = 3102, baseline mean age = 66.62 years) were used. Mixed effects models were performed with CR as independent variables and cognitive trajectories (verbal memory encoding and retrieval, verbal fluency, constructional praxis, visual attention, and memory) as outcomes. Education and leisure activities were significant positive predictors of all cognitive domains. Physical activities were a positive predictor of verbal fluency and verbal memory encoding only. Occupation was a positive predictor of verbal fluency and visual attention. Logistic regression analysis was performed to assess the relationship between CR and the risk of cognitive impairment, where education (OR: 0.79, 95% CI: 0.76, 0.83), occupational complexity (OR: 0.85, 95% CI: 0.77, 0.95), and leisure activities (OR: 0.96, 95% CI: 0.95, 0.97) were significant protective factors. Increasing the years of education can serve as a preventive strategy to delay the clinical manifestation of cognitive impairment while implementing leisure activities can act as an intervention to promote cognition even in later years.Digital media practices have varied implications for the mental health of youth, notably as a function of sociocultural and environmental factors. However, there are limited tools available to guide the assessment of digital culture in clinical practice. This study will aim to design and pilot test an interview tool for the assessment of youth digital culture, as a companion to the Cultural Formulation Interview which broadly assesses cultural factors in mental healthcare.
We will recruit youth aged 16–35 years and receiving mental healthcare in Montreal, Canada, to codesign (n=10) and evaluate (n=20) the interview tool. We will also recruit clinician participants (n=10) to provide feedback on the interview. The tool will be developed with codesign participants using the nominal group technique and subsequently tested with the evaluation participants. We will provide the evaluation participants and clinicians with a written summary of the interview and will assess their perspectives on the feasibility, acceptability and utility of the interview method through surveys and debriefing interviews. We will conduct reflexive thematic analysis of the interview transcripts and descriptive quantitative analyses of the feasibility, acceptability and utility scores.
The study received ethical approval from the Research Ethics Board of the CIUSSS de l’Ouest-de-l’Île-de-Montréal (MP-18-2025-1164). The results will be interpreted in consultation with codesign participants and will be disseminated through peer-reviewed publications, workshops for clinicians and academic conferences.
Photobiomodulation (PBM) has shown promising effects in managing postoperative pain following conventional periapical surgery, although current evidence remains limited. This study aims to assess the effect of PBM on postoperative pain 24 hours after periapical surgery.
A randomised, controlled, double-blind trial will include 34 patients undergoing periapical surgery in the maxillary region, randomly assigned to an experimental group (n=17) or control group (n=17). The experimental group will receive PBM (GaAlAs diode laser, 808 nm, 100 mW, 4 J/cm², applied at five vestibular points) and placebo ibuprofen immediately and 24 hours postoperatively. The control group will receive simulated PBM and active ibuprofen. The primary outcome is postoperative pain assessed by the visual analogue scale at 24 hours. Secondary outcomes include pain at the seventh day, paracetamol intake, oedema, ecchymosis, soft tissue status and temperature at 24 hours and 7 days. Radiographic evaluation of healing will be performed at 1 and 3 months. Statistical analysis will be conducted based on data distribution, using repeated measures ANOVA (Analysis of Variance) or non-parametric equivalents for longitudinal outcomes, and appropriate tests for categorical variables. Significance will be set at p
The study was approved by the Human Research Ethics Committee of Universidad Católica del Uruguay (process no. 220914). Results will be disseminated to participants, healthcare professionals, the public and scientific communities.
The main objective was to explore the impact of personal protective equipment and social distancing on nurses, caregivers and children's communication and relationship in a maternal and child health hospital.
The spread of COVID-19 pandemic made it necessary to apply infection prevention and control measures, including interpersonal distancing and the use of personal protective equipment. These measures may impact communication and relationship between nurses, patients and caregivers especially in a complex environment, such as a paediatric setting.
A qualitative descriptive study design was adopted. Reporting followed the COREQ guidelines.
Semi-structured interviews were conducted in two wards of a maternal and child health hospital in north-east Italy. Data were collected between September and November 2020. Transcripts were analysed using inductive content analysis.
Seventeen caregivers and 17 nurses were recruited using convenience sampling.
Three themes were identified, namely: “Impact on a trustworthy relationship”; “Impact on common communication resources”; and “Strategies to overcome barriers”. Participants agreed Covid-19 infection prevention and control measures impacted key elements of family-centred and compassionate care. Communication strategies and play were critical to overcoming the barriers encountered.
COVID-19 containment measures impact communication and family-centred care in paediatric hospital settings. There is a need for stakeholders to consider family needs in interventions aimed at controlling pandemics’ impact.
While COVID-19 pandemic urgency intensified the use of PPE and social distancing, strategies to overcome issues related to family-centred care should be considered in those wards such as oncology or infectious disease paediatric departments where these measures are continuously adopted. Beyond a greater communication awareness, strategies may comprise the implementation of virtual care to guarantee support, continuity of care and information between the child, the healthcare team and the family members that are not admitted to the hospital for safety reasons.
Only symptomatic treatments are available for patients with Parkinson’s disease (PD), the second most common chronic neurodegenerative disease worldwide, and it is therefore imperative to identify disease-modifying interventions that can alter the course of the disease. Epidemiological studies in PD patients suggest that a Mediterranean diet is associated with better motor and non-motor symptoms, slower progression and reduced mortality. Few interventional studies, however, investigated the relationship between diet and PD severity and progression. This study aims to determine whether a Mediterranean nutritional intervention can benefit motor and non-motor symptoms experienced by PD patients. As a secondary aim, the effects of a modified Mediterranean diet on the immune system, metabolomics and microbiome will also be assessed.
This is an interventional, non-pharmacological, superiority, randomised, controlled, single-centre, masked study with two parallel groups to evaluate the efficacy and safety of a modified Mediterranean diet on motor and non-motor patient-reported symptoms. PD patients meeting inclusion criteria will be enrolled (44 participants, aged between 40 years and 85 years), block-randomised and split into two parallel arms to either maintain their usual diet (control) or follow a modified Mediterranean diet for 6 months (intervention).
Patient-reported symptomatology is the primary outcome, measured through the Movement Disorders Society Unified PD Rating Scale (MDS-UPDRS) I+II score. Secondary outcomes include the immunophenotype of circulating cells of the adaptive immune system, the nasal and faecal microbiome composition, faecal and urinary metabolites and the measurement of inflammatory and metabolic markers. Disease severity (MDS-UPDRS III), non-motor symptomatology (Non-Motor Symptoms Scale), participant’s well-being (36-Item Short Form Health Survey), gastrointestinal symptomatology (Gastrointestinal Symptom Rating Scale and the Patient Assessment of Constipation Quality of Life) and intensity of dopaminergic replacement therapy (levodopa equivalents) will also be assessed. Evaluations will be conducted before the start and at the end of the intervention.
The Ethical Committee ‘Comitato Etico Territoriale Lombardia 5’ first approved this study on 17 September 2024 Prot. Nr. 420/24. Findings will be disseminated via peer-reviewed research papers and conference presentations.
Video games have been linked to a range of positive and negative effects on the mental health of adolescents and young adults. However, to better understand how games affect the mental health of young people, their use and experiences must be situated in the sociocultural and personal life contexts of individuals. Drawing from a cultural-ecosocial approach, this study combines cross-sectional and digital phenotyping measures to examine the effects of video games on the mental health of youth.
Participants will be young people aged 16–25 years from the community and living in the province of Quebec, Canada. An initial sample of 1000 youth will complete a cross-sectional survey online, including measures of socio-demographic context, gaming practices and experiences, streaming practices and experiences, as well as personality and well-being. Qualitative questions will explore personal views on games and mental health. A subsample of 100 participants will be selected for digital phenotyping, including daily surveys of well-being, gaming, streaming and social experiences, combined with passive mobile sensing (eg, geolocation). Analyses will include regression and mixed models for quantitative data, reflexive thematic analysis for qualitative data, and an integration of quantitative and qualitative results using participatory methods.
The study received ethical approval from the Institutional Review Board of McGill University (24-02-015). The dissemination of results will be conducted in partnership with a multi-stakeholder advisory committee, including youth who play video games, and will involve peer-reviewed publications, presentations to policymakers in Quebec, and workshops for clinicians and researchers.
