Climate change is causing a global climate emergency, which is increasingly seen as a major problem for global health concern.1 Climate change has far-reaching consequences for society and can impact our mental health.2 Eco-anxiety is the fear of an environmental catastrophe and is associated with symptoms of stress, anxiety, depression, insomnia and trauma.3 Nurses are exposed to the negative impact of climate change through...

Gram negative bloodstream infections (GN BSI) are a leading cause of mortality worldwide, and antibiotic treatment approaches remain understudied. BALANCE+ is a perpetual Bayesian adaptive platform trial to test multiple treatment questions for hospitalised patients with GN BSI. The vanguard phase objective was to test the feasibility of the main trial.

Adaptive platform trial with five initial domains of investigation, each with open label 1:1 randomisation.

Ten hospitals across four Canadian provinces.

Individuals admitted to hospital with blood cultures yielding Gram negative bacteria.

The five initial domains of investigation included: antibiotic de-escalation versus no de-escalation; oral transition to beta-lactam versus non-beta-lactam treatment; routine versus no routine follow-up blood cultures (FUBCs); central vascular catheter replacement versus retention; and, ceftriaxone versus carbapenem treatment for low risk AmpC organisms.

Domain-specific recruitment rates and protocol adherence.

During the vanguard phase, 719 patients were screened, of whom 563 (78.3%) were eligible, with 179 (31.8%) enrolled into the platform. The platform recruitment rate was 1.37 patients/site-week. Recruitment varied by domain: routine versus no FUBC domain 1.23 patients/site-week; oral beta-lactam versus non-beta-lactam domain 0.48; de-escalation versus no de-escalation domain 0.28; low risk AmpC domain 0.02; catheter replacement versus retention domain 0.01. Domain specific protocol adherence rates were 145/158 (91.8%) for routine versus no routine FUBC, 53/60 (88.3%) for oral beta-lactam versus non-beta-lactam, 26/33 (78.8%) for de-escalation versus no de-escalation, 3/3 (100%) for low risk AmpC, and 0/1 (0%) for line replacement versus retention. There was complete ascertainment of all study outcomes in hospital 170/170 (100%) and near complete ascertainment at 90 days 162/170 (95.3%).

The vanguard phase demonstrated overall trial feasibility by recruitment rate and protocol adherence, with differences across interventions, leading to a transition to the main BALANCE+ platform trial with minimal protocol modifications.

Dysregulated immunity may account for an increased risk of infection and other adverse outcomes among frail hospitalised persons. The primary objective of this study is to examine whether baseline frailty is associated with the risk of developing ventilator-associated pneumonia (VAP) or other intensive care unit (ICU)-acquired infections among invasively ventilated adults. Additional objectives are to examine the relationship between frailty and hospital length of stay, discharge to a long-term care facility and vital status. We hypothesise that persons with frailty compared with others would have an increased risk of VAP and other infections, a longer hospital stay, higher probability of discharge to a long-term care facility and higher mortality.

This is a preplanned secondary analysis of the PROSPECT trial (Probiotics to Prevent Severe Pneumonia and Endotracheal Colonization Trial) which enrolled patients across 44 ICUs in three countries. We will use Cox proportional hazards regression analysis to assess the association of frailty with the clinical outcomes of interest, adjusting for other baseline variables. Baseline demographic and descriptive outcome data will be reported using descriptive statistics. Regression results will be presented as adjusted HRs or ORs with 95% CIs for the associations of each independent variable with the primary, secondary and tertiary outcomes.

Participating hospital research ethics board approved the PROSPECT trial and data collection. The protocol for this study was approved by the Hamilton Integrated Research Ethics Board on 20 August 2015 (Project ID:19128). This study will identify whether frailty is associated with risk of VAP and other healthcare-associated infections in invasively ventilated patients, adjusted for other baseline factors. Results may be useful to patients, their caregivers, clinicians and the design of future research. Findings will be disseminated to investigators at a meeting of the Canadian Critical Care Trials Group. We will present study results at an international conference in the fields of critical care and infectious diseases, to coincide with or precede open-access peer-review publication. To aid knowledge dissemination, we will use a variety of formats. For example, for traditional and social media, we will create two different visual abstracts and infographics of our results suitable to share on clinician-facing and public-facing platforms.

Excessive opioid prescribing after surgery can lead to adverse events and exacerbate the opioid crisis. Patients undergoing outpatient breast surgery are often prescribed opioids to manage pain at home; however, the value of this approach is uncertain. The Postoperative Analgesia Intervention with Non-opioid Alternatives (PAIN Alt) trial will address the following research question: among patients undergoing outpatient breast surgery, does opioid-free analgesia (OFA) result in non-inferior 7-day pain intensity and pain interference in comparison to opioid analgesia (OA)?

This is a parallel, assessor-blind, open-label randomised trial conducted at seven university-affiliated hospitals in Canada. A sample of 540 adult patients (>18 years) undergoing outpatient mastectomy or lumpectomy will be included. Participants are allocated 1:1 to receive OA (around-the-clock non-opioids and opioids for breakthrough pain) or OFA (around-the-clock non-opioids, with adjustment of non-opioid drugs and/or non-pharmacological interventions for breakthrough pain). The co-primary outcomes are 7-day pain intensity and pain interference (measured using the Brief Pain Inventory). Secondary outcomes include adverse drug events, physical and mental health status, satisfaction with pain management, postoperative complications, chronic pain, opioid misuse, persistent opioid use, healthcare utilisation and costs. The primary statistical analyses will follow the intention-to-treat principle and be conducted using mixed-effects modelling.

This trial is coordinated by the McGill University Health Centre (ethics approval MP-37-2024-102530), with ethics approval being sought at all participating sites. Our results will be published in an open-access, peer-reviewed journal, presented at relevant conferences and disseminated to the public through press releases.

Despite increasing palliative care capabilities in the USA, utilisation rates remain low for patients with advanced cancer, particularly among African American patients. To address this gap, a theory-driven, stakeholder-informed community health worker (CHW) palliative care intervention for African American patients with advanced cancer and their informal caregivers is currently being assessed through a hybrid type 1 effectiveness-implementation trial at four cancer centres across the USA. To improve the quality and efficiency of palliative care delivery, inform resource allocation and guide broad-scale implementation, it is essential to generate evidence on the economic value of palliative care programmes. The objectives of this study are to evaluate the cost-effectiveness and estimate the social value of a CHW palliative care intervention for African American patients with advanced cancer and their caregivers.

We will conduct cost-effectiveness analyses (CEAs) and a social return-on-investment (SROI) analysis to assess the value of the CHW palliative care intervention compared with enhanced standard of care. Standard, extended and distributional CEAs will be performed from the perspectives of an adopting organisation or payer (eg, Medicaid), the US healthcare sector and society. An SROI analysis will also be conducted to assess the social value of the intervention. These analyses will focus on estimating the costs, health and distributional impacts of the intervention.

This study protocol was approved by the Johns Hopkins Medicine Institutional Review Board (IRB00372476). All methods will be carried out in accordance with relevant guidelines and regulations. Written informed consent will be obtained from all subjects prior to study participation. This manuscript does not contain participant-level data. The full protocol will be available from the corresponding author on reasonable request. The dissemination of findings from the clinical trial and accompanying economic evaluation outlined in this manuscript will be multifaceted to maximise reach and impact. Research findings will be presented at relevant scientific conferences, submitted for publication in peer-reviewed journals and shared with community stakeholders, including hospital leaders and administrators, providers, CHWs and patient advocacy groups.

Tuberculosis (TB) is a major global cause of morbidity and mortality. Emerging evidence in high-burden settings suggests significant long-term sequelae among people surviving TB; however, evidence from high-income, low-TB burden settings like Canada is lacking. In a person with TB infection, provision of TB preventive treatment (TPT) can prevent TB disease and its sequelae, but remains underused. We propose the Functional Outcomes, Lung health and Livelihood Outcomes among people With Tuberculosis study, a multicentre, prospective cohort study in Canada to help improve our understanding of the impacts of TPT and TB disease on individuals.

This is a prospective cohort study taking place in Montreal and Vancouver, Canada. We aim to recruit and retain at least 120 people with microbiologically confirmed TB disease, 340 people treated for TB infection and 120 without TB disease or infection who will be considered our unexposed group. All participants must be ≥6 years of age. Participants with TB disease or infection will be recruited within 2 weeks of treatment initiation. We will follow-up unexposed participants and participants with TB disease for 24 months, and participants with TB infection for 12 months. Throughout follow-up, participants will complete assessments measuring lung health and function, quality of life, disability, dyspnoea, psychological distress, as well as changes in employment and direct and indirect costs incurred because of treatment. Among participants with TB disease, our primary outcome is the difference in quality-adjusted life years between participants with TB disease and those unexposed at 24 months. For participants with TB infection, our primary outcome is the identification of non-patient characteristics (eg, patient cost, quality of life) associated with participant decision to discontinue treatment. Patient partners have contributed to the design of the study and will be involved with the study through to its dissemination.

This study has been approved by institutional ethics review boards at The Research Institute of the McGill University Health Centre (2025–10344) and The University of British Columbia (H24-02071). All participants will provide informed consent (and assent, if required) prior to participating in the study. We will disseminate study results to participants, national and international organisations, and through open-access peer-reviewed academic journals and conferences.

Documenting evidence on global health strategies and programmes that provide safeguards for vulnerable populations and strengthen overall pandemic preparedness is essential. This study aimed to identify factors associated with adherence to COVID-19 mitigation measures, COVID-19-related symptoms and testing, as well as pandemic-related income loss among internally displaced persons (IDPs) in urban and remote areas of Burkina Faso, Niger and Mali.

This cross-sectional study used fixed-site respondent-driven sampling (RDS).

Primary care settings across six urban and remote locations in Burkina Faso, Mali and Niger.

4144 internally displaced adults, who had been forced from their homes within 5 years of the survey, participated in the study. The survey was conducted between August and October 2021 in two selected locations in three countries: Kaya (n=700) and Ouahigouya (n=715) in Burkina Faso; Bamako (n=707) and Ménaka (n=700) in Mali; and Niamey (n=733), and Diffa (n=589) in Niger. Participants were included if they were born in the study countries, displaced due to conflict, violence or disaster, aged 18 years or older, and living or working in the study site for at least 1 month.

The primary outcomes measured were adherence to COVID-19 mitigation measures, presence of COVID-19 symptoms, COVID-19 testing and vaccination rates and pandemic-related income loss.

Among 4144 IDPs surveyed across 6 sites in Burkina Faso, Mali and Niger, over half (52%) reported experiencing at least one COVID-19 symptom in the preceding 2 weeks. However, 8% had ever been tested for COVID-19, and fewer than 5% had received a vaccine in all sites except Diffa, where 54% reported vaccination. While willingness to be vaccinated was high (ranging from 56.6% in Bamako to 89.5% in Niamey), access remained limited. Compliance with public health measures varied; for example, 41.7% of IDPs were able to maintain physical distance from non-household members, and just 60.2% reported wearing a mask. Chronic health conditions were consistently associated with higher odds of COVID-19 symptoms (Ménaka OR: 14.65; 95% CI: 7.36 to 29.17). Economic vulnerability was widespread, with more than half of IDPs in Bamako (58.1%) and Niamey (66.4%) reporting income loss due to the pandemic, and average monthly income declining by over 50% in most sites. IDPs in urban areas generally reported greater exposure to COVID-19 risk factors, while those in remote settings reported lower adherence and poorer access to basic preventive measures.

This is the first known RDS study to explore the impact of the COVID-19 pandemic on IDPs. Findings suggest that IDPs in urban areas may face heightened risks of exposure and infection, underscoring the need to prioritise them in public health efforts. Low testing and vaccination rates and significant income loss call for advocacy and economic relief to address these vulnerabilities. Future pandemic responses should integrate health interventions with targeted support, especially mitigating income loss to bolster IDPs’ resilience.

The TRAjectory of knee heaLth in runners (TRAIL) study is a prospective cohort study investigating the long-term knee health trajectories of runners with and without a heightened osteoarthritis risk. This study aims to describe the recruitment results and baseline characteristics of the TRAIL cohort.

Runners aged 18–50 years and running ≥3 times and ≥10 km per week on average in the past 6 months were eligible. Participants were recruited via running podcasts, running clubs and social media between July 2020 and August 2023. Data were collected at study enrolment and at a face-to-face baseline testing session, which occurred a median of 33 weeks (IQR 18 to 86 weeks) after enrolment. Follow-up data collection is ongoing.

Out of 462 runners who completed an online registration form, 268 runners enrolled, of which 135 had a history of knee surgery (46% females) and 133 were non-surgical controls (50% females). 60% of the surgery group had undergone anterior cruciate ligament reconstruction, 33% meniscus and/or cartilage surgery, and 7% other knee surgery. 54 participants previously enrolled were unable to continue in the study before attending baseline data collection. Of the 214 runners who remained in the study and attended baseline data collection, 108 had a history of knee surgery (49% females) and 106 did not have a history of knee surgery (51% females).

Participants will be followed for 10 years through ongoing patient-reported outcomes and continuous monitoring of training loads using wearable devices. At baseline, 4- and 10-year follow-up, knee MRI and knee-health patient-reported outcomes will be collected to evaluate structural and symptomatic knee osteoarthritis progression. Data will inform guidelines for safe running practices and rehabilitation post-knee surgery.

Amyotrophic lateral sclerosis (ALS) is a rapidly progressive, fatal motor neuron disease. Diagnostic delay severely impairs patient access to ALS multidisciplinary clinics, available disease-modifying medications and therapies that may prolong survival.

To investigate how patient and physician perspectives might be leveraged to promote timely ALS diagnosis, and how system-level barriers might be addressed to promote appropriate referral to ALS multidisciplinary care.

A qualitative study in Alberta, Canada, used human-centred design and interviews to map the diagnostic journeys of ALS patients and identify individual-level and system-level diagnostic barriers and opportunities.

30 semistructured interviews (10 patients; 20 physicians) were conducted. Data were inductively analysed with the aid of Miro board software. Patient and physician data were triangulated to identify key phases of the journey from symptom onset to confirmed ALS diagnosis and themes related to the diagnostic barriers and opportunities. Journey maps were created to visualise the diagnostic journey.

Patient journeys were comprised of five phases and commonly involved iterative cycles of referral and testing before an ALS diagnosis was confirmed. Four primary themes related to diagnostic barriers: difficulty recognising and responding effectively to early-stage ALS symptoms, absence of a single definitive diagnostic test, long wait times between referrals and clinical visits, and physician reluctance to pronounce an ALS diagnosis. Analysis indicated three approaches for improving diagnostic processes: increase ALS awareness; improve communication between referring physicians and physicians receiving referrals (consultants); and develop physician, diagnostic testing and multidisciplinary clinic referral forms that will guide symptom assessment and accurate referral.

Timely ALS diagnosis is challenging for patients navigating the frequently prolonged, circuitous diagnostic journey and physicians who struggle with referral pathways and the efficient diagnosis of this rare disease. Findings demonstrate the importance of increased ALS awareness and effective communication and response within referral pathways. Recommendations include strengthening the clinical approach of community-based physicians and supporting access and referral pathways. Current initiatives arising from this investigation seek to achieve meaningful change in timely referrals for progressive neurological diseases like ALS.

To investigate discrepancies in perceptions regarding the accessibility and availability of rest and relaxation (R&R) spaces between hospital doctors in Scotland and NHS Scotland regional health boards (HBs), with the intention of informing best practices for organisational policy on the provision of R&R spaces both now and in the future.

A qualitative study, through an inhabited institutionalism (II) lens, of semi-structured interviews of hospital doctors across the career continuum in Scotland and all NHS regional HBs in Scotland providing written information relating to R&R space provision.

NHS Scotland during the COVID-19 pandemic and beyond.

Hospital doctors (n=30) who had participated in a larger qualitative study and provided specific insights on R&R spaces. All NHS Scotland regional HBs (n=14).

Although HBs reported the provision of R&R spaces, numerous doctors reported R&R spaces had been removed, relocated or were inaccessible. Furthermore, limited awareness of their availability attributed to inadequate communication, compounded the issue. This divergence between institutional reporting and front-line experience can be interpreted through the lens of II, which posits that institutional polices are often interpreted and implemented differently.

This study emphasises how crucial R&R spaces are to promoting doctors’ well-being especially during the time of high stress. HBs must not only guarantee the accessibility and physical availability of R&R spaces but also enhance their communication regarding the provision.
