Music-based training programmes, such as learning how to play an instrument or sing in a choir, have been suggested as potential interventions for promoting healthy brain ageing in older adults at risk of cognitive decline because of their ability to enhance cognitive functions and potentially promote neuroplasticity. However, there is limited empirical evidence in older adults at risk of dementia, especially that evaluates both piano and singing interventions and their effects on cognition and neuroplasticity. In this protocol, we outline a study to assess the efficacy of keyboard and singing music training programmes on reducing cognitive decline and other outcomes in older adults with Mild Cognitive Impairment (MCI).

This randomised, single-blind, controlled, parallel-group trial aims to enrol 432 individuals with MCI from the community in Sydney, Australia. Participants are randomly allocated to participate in either keyboard lessons, singing lessons or a film discussion control group once a week for 3 months. The primary objective is to assess the effectiveness of two music training programmes (keyboard and choral singing) for enhancing verbal memory after 3 months compared with control. Additionally, we will examine how these music-based interventions affect other aspects of cognition, mood, sleep, overall well-being, markers of brain plasticity and blood biomarkers of Alzheimer’s disease and neurodegeneration. Tertiary objectives are to identify factors that impact the success of the interventions, such as participation rates, engagement levels and key demographic and clinical features. Outcomes are collected at baseline and at 3 and 9 months. The primary endpoint analysis will include all randomised participants to estimate the treatment effect using intention-to-treat principles. Primary and secondary outcomes will be analysed using linear mixed models and effect size measures will be calculated.

This study will be the first robust, randomised controlled trial to assess the potential and relative value of music engagement for cognitive decline in high-risk MCI individuals, as well as broader effects on other markers of mental health, well-being and neurodegeneration. Co-designed with implementation in mind, the music interventions can potentially be delivered within memory clinic or community settings.

Forming secure attachment relationships provides children with the best possible start to life. Children from families with high psychosocial vulnerability and complex mental health needs (eg, caregivers with lived experience of trauma, experiencing mental illness or substance abuse, current or past domestic violence, and/or current or a history of child protection issues) are at the greatest risk of experiencing attachment disturbances. Nurturing Connections is a new early intervention service launched by the New South Wales State Ministry of Health targeting both caregiver adversity and the caregiver-child attachment relationships in families with high psychosocial vulnerability and complex mental health needs. This paper outlines the evaluation protocol of the Nurturing Connections Programme.

A mixed-methods design will be used to undertake an implementation and outcomes evaluation. The study will draw on both qualitative and quantitative data, including routinely collected service data, surveys, participant observations, and semi-structured interview and yarning circle data. Appropriate descriptive and inferential techniques will be used to analyse quantitative data while thematic analysis will be drawn on to analyse qualitative data.

This research was approved by the South Eastern Sydney Local Health District Research Ethics Committee (2024/ETH01715). The Mid North Coast Local Health District also received ethics approval from the Aboriginal Health and Medical Research Council of New South Wales (2380/25). Evaluation findings will be shared via published manuscripts, conference presentations, as well as a final report to funding bodies.

Adolescent pregnancy is a global issue. Early childbearing is strongly linked to poverty and negative health outcomes, including increased neonatal death risk. This study explores spatial patterns of adolescent pregnancies and neonatal deaths and their association with socioeconomic characteristics.

This population-based study used spatial analysis techniques to investigate the geographical distribution of adolescent pregnancies, socioeconomic characteristics and neonatal mortality rate (NMR).

The 645 municipalities of State of Sao Paulo, Brazil.

All live births to mothers residing in the State of Sao Paulo, Brazil, between 2004 and 2020.

The socioeconomic indicators used were: municipal human development index and per capita income (PCI). Spatial patterns were assessed for spatial autocorrelation (Moran’s I, LISA), and smoothed using local Bayesian estimation. Spearman’s correlation was used to ascertain the relationship between the percentage of live births to adolescent mothers and socioeconomic indexes. This calculation was also undertaken between different maternal age groups of NMR.

The study analysed over 10 million live births, with 14.3% attributed to adolescent mothers. Spatial analysis revealed significant clustering of adolescent pregnancies, strongly associated with lower socioeconomic indicators. NMR also exhibited spatial clustering, particularly after smoothing. Statistically significant differences were observed in PCI medians between high–high and low–low clusters for adolescent births. High and low incidence areas of NMR, both in all maternal ages and stratified by adolescent and non-adolescent mothers, demonstrated considerable overlap.

The results indicated the existence of clustering areas of adolescent pregnancy and neonatal deaths and suggested that the prevalence of births to adolescent mothers is not distributed equally and is higher in lower socioeconomic developed areas.

Tobacco use accounts for approximately 1.35 million deaths annually in India, disproportionately affecting low-income individuals, men, rural residents, those without formal education and groups of low socioeconomic status (SES). Despite progress in tobacco control, scalable, low-cost solutions, such as brief advice interventions, are needed. This study explored priority implementation determinants for adapting an evidence-based brief advice/counselling intervention for high-reach, low-resource settings in Mumbai, India. The focal settings (health-focused and tuberculosis-focused non-governmental organisations (Health NGOs and TB NGOs) and dental clinics) served low-SES populations.

Mumbai-based and US-based team members conducted a qualitative study employing semistructured interviews to gather data from four groups connected to Health and TB NGOs and dental clinics: (1) 15 patients, (2) 33 practitioners, (3) nine practice leaders and (4) three policymakers. We used a team-based, critical, reflexive thematic analysis approach to analysis, grounded in the Exploration, Preparation, Implementation and Sustainment framework. We managed data with Nvivo software.

Participants were supportive but highlighted diverse challenges and supports required for implementing the intervention in these diverse settings. First, many noted that societal constraints such as economic insecurity and cultural factors were expected to limit tobacco control efforts for low-SES populations. Second, setting-specific intervention adaptations were identified as necessary to support integration and ensure access to support for all patients. Various participant groups highlighted different adaptation areas. For example, patients noted that tobacco was part of their routines and social lives, practitioners emphasised the need to design implementation plans that support integration alongside existing needs, and policymakers highlighted the need for uniform implementation strategies.

Adapting brief advice/counselling interventions for Health NGOs, TB NGOs and dental clinics in Mumbai will require strategic communication to support buy-in, thoughtful workflow integration and changes to funding and support mechanisms for organisations so meaningful reductions in tobacco use can be achieved among low-SES groups. In other words, there is a need to adapt both the intervention and the implementing system to allow for brief advice/counselling to contribute to broader tobacco control efforts.

Mobile diagnostic imaging services provided at home increase accessibility and convenience, particularly for older adults, people with disabilities and other vulnerable groups. These services can reduce the need for patient travel and support the routine monitoring of chronic conditions. However, current guidelines often overlook user acceptance and environmental considerations within the home setting.

To map studies that identify the models, barriers and facilitators for performing home-based diagnostic imaging/graph according to end users.

A scoping review was conducted following the methodological framework of the Joanna Briggs Institute and reported according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews checklist.

Studies that addressed mobile or portable diagnostic imaging or graph examinations conducted in the home for individuals of any age or health status were included. Studies were eligible if they reported on barriers, facilitators or user experiences. Studies that focused on wearable technologies were excluded.

The search strategy was developed using terms related to home-based diagnostic imaging/graph, portability, home setting and user perceptions. Searches were conducted in PubMed, Web of Science, Scopus, Embase, The ACM Guide to Computing Literature and LILACS, without restrictions on publication date or language. Additional grey literature was identified through Google Scholar.

Two reviewers independently extracted data using a standardised form that captured study characteristics, types of procedures, target populations and reported barriers and facilitators. Quantitative data were summarised using absolute and relative frequencies. Qualitative findings were synthesised through basic content analysis to identify and categorise recurring themes.

Data were charted in tables to organise and visually map study contexts, methodological features and thematic patterns related to implementation and user experience.

Twenty-six studies published between 1998 and 2023 across 15 countries were included. The diagnostic examinations included mostly polysomnography, X-ray imaging and ultrasonography. Seven categories of barriers were identified, such as physical discomfort, equipment-related challenges and procedural limitations. Seven facilitators were also reported, including perceived comfort, patient satisfaction and equipment usability.

This review identifies key factors affecting the delivery and user experience of mobile diagnostic imaging at home, including logistical, technical and environmental aspects. It reveals gaps in the literature and provides a basis for future research to inform more inclusive and effective public health policies and service design.

Hospitalisation is one of the most stressful life events for older adults, particularly for those who are pre-frail or frail. Multi-component community-based interventions have the potential to address the complex needs of older adults post-acute care admission. While some available interventions have been developed with end-user engagement, fully involving older people who are pre-frail or frail in the design of interventions has been less common. Multi-component community-based interventions that address the needs of older adults and their care partners with potential implementation barriers informed by healthcare providers, community partners and health system decision makers are needed. This protocol paper describes the planned process of co-designing for older patients discharged into the community, a Post-Acute Care Intervention for Frailty using Information and Communication technology.

The development of a complex multi-component frailty intervention which meets older people’s needs involves several concurrent tasks and methodologies, each informed by co-design and conducted with consideration to eventual implementation. These tasks include: (1) establishing a Research Advisory Board, (2) assessing the feasibility and validity of using hospital administrative data to identify frail or pre-frail older adults and their needs, (3) conducting a needs assessment of patients returning to the community, (4) mapping community assets to identify existing programmes and services to help tailor the intervention, (5) co-designing a multicomponent frailty intervention, (6) selecting study outcome measures and (7) selecting and tailoring a digital health patient portal to support intervention delivery, data capture and communication.

Each task requiring ethics approval will be submitted to the Hamilton Integrated Research Ethics Board at McMaster University. Results will be disseminated through peer-reviewed journal articles, conferences and networks of relevant knowledge users who have the capacity to promote dissemination of the results. A toolkit will be developed to help researchers and healthcare providers replicate the methodology for other populations.

Dyspnea is a common chief complaint leading to emergency department (ED) visits. Multiple conditions may cause or be associated with dyspnoea, including bacterial pneumonia, acute heart failure (AHF), exacerbation of chronic obstructive pulmonary disease (COPD) or asthma and pulmonary embolism. Each of these diagnoses has a specific treatment recommended by international guidelines. Inappropriate treatment in the ED is more frequent among elderly patients and is independently associated with in-hospital mortality. Point-of-care ultrasound is immediately available at the bedside. Lung and cardiac ultrasound (LuCUS) offers excellent diagnostic accuracy for bacterial pneumonia, AHF and COPD exacerbations, even in elderly patients. The primary objective of the LUC REED trial is to evaluate the impact of a LuCUS-guided strategy versus standard care on reducing inappropriate treatment of dyspnoea in elderly ED patients.

The LUC REED trial is a prospective, interventional, multicentre, stepped-wedge randomised controlled trial designed to assess the superiority of a LuCUS-guided strategy over standard care in ensuring treatment appropriateness for dyspnoea in elderly ED patients. The study will include 504 patients over 2 years. Patients aged >65 years presenting with acute dyspnoea and signs of severity (respiratory rate ≥22 or SpO₂

Acute abdominal pain is a chief complaint in emergency departments and represents 7%–10% of emergency room (ER) visits. Acute appendicitis represents 15% of the causes of abdominal pain and 62% of the causes that require surgical treatment. Opioid analgesia has been evaluated in clinical trials, and they have determined it does not impact diagnostic accuracy. Despite evidence, withholding analgesia is still a common practice. Pain severely impacts quality of life and analgesia has become essential in humanised medicine. We aim to determine the safety and effectiveness of different opioid regimens for adult patients that present to the ER with acute suspected appendicitis.

We will search MEDLINE and Embase via Ovid, and the Cochrane Central Register of Controlled Trials without restrictions on the study publication date. Screening, extraction and risk of bias assessment will be performed in duplicate. We will use the Cochrane Risk of Bias Assessment Tool. We will perform both pairwise meta-analysis and network meta-analysis (NMA) if transitivity and coherence principles are met. Heterogeneity will be evaluated using the I² and ² and using the thresholds recommended by Cochrane. We will perform sensitivity analysis based on the pre-established potential effect modifiers, risk of bias and data that required transformation or imputation. Publication bias will be addressed by using funnel plots on a pairwise level. We will assess the strength of the body of evidence using the Grading of Recommendations Assessment, Development and Evaluation approach (GRADE) per outcome, and evidence from the NMA will be assessed using the GRADE approach for NMA.

Approval by an ethics committee is not required for this study since no personal information will be handled. Information will be disseminated by publication on a peer-reviewed journal.

SARS-CoV-2 is now endemic and expected to remain a health threat, with new variants continuing to emerge and the potential for vaccines to become less effective. While effective vaccines and natural immunity have significantly reduced hospitalisations and the need for critical care, outpatient treatment options remain limited, and real-world evidence on their clinical and cost-effectiveness is lacking. In this paper, we present the design of the Canadian Adaptive Platform Trial of Treatments for COVID in Community Settings (CanTreatCOVID). By evaluating multiple treatment options in a pragmatic adaptive platform trial, this study will generate high-quality, generalisable evidence to inform clinical guidelines and healthcare decision-making.

CanTreatCOVID is an open-label, individually randomised, multicentre, national adaptive platform trial designed to evaluate the clinical and cost-effectiveness of therapeutics for non-hospitalised SARS-CoV-2 patients across Canada. Eligible participants must present with symptomatic SARS-CoV-2 infection, confirmed by PCR or rapid antigen testing (RAT), within 5 days of symptom onset. The trial targets two groups that are expected to be at higher risk of more severe disease: (1) individuals aged 50 years and older and (2) those aged 18–49 years with one or more comorbidities. CanTreatCOVID uses numerous approaches to recruit participants to the study, including a multifaceted public communication strategy and outreach through primary care, outpatient clinics and emergency departments. Participants are randomised to receive either usual care, including supportive and symptom-based management, or an investigational therapeutic selected by the Canadian COVID-19 Outpatient Therapeutics Committee. The first therapeutic arm evaluates nirmatrelvir/ritonavir (Paxlovid), administered two times per day for 5 days. The second therapeutic arm investigates a combination antioxidant therapy (selenium 300 µg, zinc 40 mg, lycopene 45 mg and vitamin C 1.5 g), administered for 10 days. The primary outcome is all-cause hospitalisation or death within 28 days of randomisation.

The CanTreatCOVID master protocol and subprotocols have been approved by Health Canada and local research ethics boards in the participating provinces across Canada. The results of the study will be disseminated to policy-makers, presented at conferences and published in peer-reviewed journals to ensure that findings are accessible to the broader scientific and medical communities. This study was approved by the Unity Health Toronto Research Ethics Board (#22-179) and Clinical Trials Ontario (Project ID 4133).

Non-communicable diseases (NCDs), such as diabetes, cardiovascular diseases and cancer, are major global public health concerns. Diet quality—particularly the consumption of ultra-processed foods—has been associated with increased risk of NCDs. Traditional cohort studies are often expensive and logistically complex. The NutriNet-Brasil cohort leverages a web-based approach, offering a cost-effective and practical solution for comprehensive data collection and long-term follow-up.

Recruitments began in January 2020 through mass media, social media campaigns and collaborations with health organisations. Eligible participants are adults (aged ≥18 years) living in Brazil with internet access. Participants complete self-administered online questionnaires covering dietary intake, health status and other health determinants. Dietary assessment is based on the Nova classification system, which categorises foods by their level of processing.

Over 88 000 participants have completed the initial questionnaire. The cohort is predominantly women (79.9%) and highly educated (67.9% had completed higher education). The web-based design enabled the development and application of innovative dietary assessment tools, including the Nova24h and the Nova24hScreener, specifically designed to evaluate food processing levels. These tools have shown good performance in capturing dietary patterns and are central to the cohort’s aim. The online platform facilitates efficient recruitment, data collection and participant retention.

NutriNet-Brasil is pioneering the development of web-based cohort methodologies and instruments tailored to food processing research. Future work includes leveraging collaborations with national and international research centres to conduct multidisciplinary analyses and inform public health policies.

Elder neglect by both informal and formal caregivers is common, particularly among persons with dementia, and has serious health consequences but is under-recognised and under-reported. Persons with dementia are often unable to report neglect due to memory and language impairments, increasing their vulnerability. Screening for elder mistreatment and initiation of intervention in primary care clinics may be helpful, but few evidence-based tools or strategies exist. We plan to: (1) develop a novel primary care screening tool to identify elder neglect in persons with dementia, (2) develop an innovative technology-driven intervention for caregivers and (3) pilot both for feasibility and acceptability in primary care.

We will use a multistep process to develop a screening tool, including a modified Delphi approach with experts, and multivariable analysis comparing confirmed cases of neglect in patients with dementia from the existing data registry to non-neglected controls. We will develop an evidence-based, technology-driven caregiving intervention for neglect with an expert panel and iterative beta testing. Following the development of the protocol for implementation of the tool and intervention with associated training, we will pilot test both the tool and intervention in older adult patients and caregivers. We will conduct provider focus groups and interviews with patients and caregivers to assess usability and will modify the tool and intervention. These studies are in preparation for a future randomised trial.

Initial phases of this project have been reviewed and approved by the Weill Cornell Medicine Institutional Review Board, protocol #22-06024967, with initial approval on 1 July 2022. We aim to disseminate our results in peer-reviewed journals, at national and international conferences and among interested patient groups and the public.
