Objectives

To identify enablers and barriers for scaling up non-communicable disease (NCD) interventions across diverse global contexts and to map these factors to the WHO’s health system building blocks.

Design

A multi-method qualitative study applying the Consolidated Framework for Implementation Research to analyse data from multiple projects nearing or completing scale-up.

Setting

Global Alliance for Chronic Diseases-funded implementation research projects conducted across 18 low- and middle-income countries and high-income settings.

Participants

Data was derived from documents (n=77) including peer-reviewed publications, policy briefs, and reports and interviews with stakeholders (n=18) (eg, principal investigators, medical professionals, public health workers).

Interventions

Various context-specific interventions targeting sustainable scale-up of NCD (eg, diabetes, hypertension, cardiovascular disease) interventions at the community, primary care or policy levels.

Primary and secondary outcome measures

The primary outcome was identifying contextual enablers and barriers to intervention scale-up. Secondary outcomes included exploring how these factors aligned with health system building blocks (eg, leadership/governance, healthcare workforce).

Results

Twenty enablers (eg, intervention adaptability, strong stakeholder engagement, local empowerment) and 25 barriers (eg, resource limitations, intervention complexity, stakeholder burnout) were identified. Contextual alignment, supportive governance and capacity building were critical for sustainability, while cultural misalignment and socio-political instability frequently hampered scaling efforts.

Conclusions

Tailoring interventions to local health systems, ensuring stakeholder co-ownership and incorporating strategies to mitigate stakeholder burn-out are essential to achieving sustainable, scalable NCD solutions. Future research should focus on integrating systematic cultural adaptation, sustainable financing and workforce capacity building into scale-up planning.

Triadic relationships between pasture exposure, gastrointestinal parasites, and hindgut microbiomes in grazing lambs

by Jack Jefferson, Claire Reigate, Alessandra Giacomini, M. Jordana Rivero, Matthew Hitchings, Tamsyn Uren Webster, Konstans Wells

Livestock grazing in confined pastures often means grazing on a less diverse diet than under more natural conditions and increased exposure to gastrointestinal parasites prevailing in these pastures. However, how sward composition influences gut microbiome (GM) diversity and its relationship with parasite burden remains poorly understood. In this study, we analysed the faecal GM of weaned lambs grazing on two distinct sward types (perennial ryegrass and a mixed-species sward) over three consecutive months using 16S rRNA sequencing, in order to assess how microbial diversity and composition are related to environmental conditions and the gastrointestinal nematode (GIN) burden in naturally infected lambs. Sward type and sampling time explained some of the variation in GM alpha diversity and community composition (beta diversity), whereas individual lamb identity accounted for considerably more variation in microbial assemblages. Shifts in the relative abundance of bacterial genera such as Saccharofermentans, Anaerosporobacter, Butyrivibrio in relation to sward type and sampling time suggest mostly adaptive fluctuations in response to diet and pasture condition. Abundance shifts of Negativibacillus, and Candidatus Saccharimonas were also associated with GIN burden, which, in turn, was higher in lambs grazing on mixed swards compared to ryegrass. Our findings add to the growing understanding of how sheep microbiomes vary with pasture management and changes in parasite burden. We highlight that individual identity may shape gut microbiota, and that potential triadic interactions among gastrointestinal parasites, sward exposure, and the gut microbiome underscore the importance of considering host, parasite, and environmental factors collectively when evaluating microbiome dynamics in grazing livestock.

Introduction

The incidence of anal carcinoma is increasing, with the current gold standard treatment being chemoradiotherapy. There is currently a wide range in the radiotherapy dose used internationally which may lead to overtreatment of early-stage disease and potential undertreatment of locally advanced disease.

PLATO is an integrated umbrella trial protocol which consists of three trials focused on assessing risk-adapted use of adjuvant low-dose chemoradiotherapy in anal margin tumours (ACT3), reduced-dose chemoradiotherapy in early anal carcinoma (ACT4) and dose-escalated chemoradiotherapy in locally advanced anal carcinoma (ACT5), given with standard concurrent chemotherapy.

Methods and analysis

The primary endpoints of PLATO are locoregional failure (LRF)-free rate for ACT3 and ACT4 and LRF-free survival for ACT5. Secondary objectives include acute and late toxicities, colostomy-free survival and patient-reported outcome measures. ACT3 will recruit 90 participants: participants with removed anal tumours with margins ≤1 mm will receive lower dose chemoradiotherapy, while participants with anal tumours with margins >1 mm will be observed. ACT4 will recruit 162 participants, randomised on a 1:2 basis to receive either standard-dose intensity modulated radiotherapy (IMRT) in combination with chemotherapy or reduced-dose IMRT in combination with chemotherapy. ACT5 will recruit 459 participants, randomised on a 1:1:1 basis to receive either standard-dose IMRT in combination with chemotherapy, or one of two increased-dose experimental arms of IMRT with synchronous integrated boost in combination with chemotherapy.

Ethics and dissemination

This study has been approved by Yorkshire & The Humber – Bradford Leeds Research Ethics Committee (ref: 16/YH/0157, IRAS: 204585), July 2016. Results will be disseminated via national and international conferences, peer-reviewed journal articles and social media. A plain English report will be shared with the study participants, patients’ organisations and media.

Bereavement in haemodialysis units: a scoping review of the perspectives and experiences of patients and nursing staff and support strategies

Por: Massey · C. C. · Conway · J. · Webster · E.
Objectives

Frequent haemodialysis creates close-knit communities within treatment units, where high patient mortality contributes to significant grief among patients and staff. Despite the emotional toll, support for grief and bereavement in these settings remains limited, and recent data are lacking. This scoping review aims to explore how patients and nursing staff within haemodialysis units experience and cope with bereavement, and to identify support strategies currently used or desired to inform future, culturally sensitive approaches, particularly in Australia.

Design

Scoping review conducted in accordance with the Joanna Briggs Institute methodology.

Data sources

A comprehensive search was conducted using the Clinical Information Access Portal, supplemented by grey literature and the Elicit AI Research Assistant tool.

Eligibility criteria

We included literature exploring patient and nurse perspectives on grief and bereavement in haemodialysis units. Studies outside the haemodialysis setting and non-English studies were excluded. There were no geographical or publication year limitations.

Data extraction and synthesis

Two reviewers independently screened titles, abstracts and full texts, with discrepancies resolved by consensus. A data extraction table was used to collect study characteristics and key findings. Thematic analysis was applied to synthesise data across studies.

Results

17 publications from 1998 to 2021 were identified across five countries. Grief and bereavement following patient death profoundly shape haemodialysis unit dynamics. Patients form familial bonds and experience deep grief when peers die, while nurses face emotional stress and burnout. Reported support strategies include memorial services, peer and staff support, counselling and debriefing and spiritual care.

Conclusions

This study describes grief experiences, support strategies and cultural implications in haemodialysis units, which serve a culturally diverse group of people. By consolidating available knowledge, this review provides a critical platform for future empirical work and calls for culturally sensitive support and larger, diverse samples in future research.

Objective

To assess the impact of opening a large community-based asynchronous review ophthalmic clinic on attendance delays among patients with stable chronic eye disease attending a London teaching eye hospital network.

Design

Interrupted time-series analysis of routine electronic health records of appointment attendances.

Setting

A large eye hospital network with facilities across London, UK, between June 2018 and April 2023.

Participants

We analysed 69 257 attendances from 39 357 patients, with glaucoma and medical retina accounting for 62% (n=42 982) and 38% (n=26 275) of visits, respectively. Patients over 65 made up 54% (n=37 824) of attendances, while 53% (n=37 014) were from the more deprived half of the population, and 51% (n=35 048) were males.

Intervention

An asynchronous review clinic opened in a shopping centre in London, in autumn 2021, following the COVID-19 lockdown in spring 2020.

Main outcome measures

Average attendance delays (days), calculated as the difference between follow-up attendance date and the latest clinically appropriate date determined at the preceding attendance.

Results

Pre-COVID-19, attendance delays for chronic eye disease monitoring were increasing by 0.9 days per week (95% CI, 0.8 to 0.9) on average, worsening to 2.0 days per week (95% CI, 2.0 to 2.0) after the first COVID-19 national lockdown, mid-March 2020. Opening the asynchronous review clinic increased appointment capacity, with delays decreasing on average by 8.1 days per week (95% CI, 8.1 to 8.2) shortly after opening. The rate of decrease slowed to 0.3 days per week (95% CI, 0.3 to 0.3) after 5 months. We found no significant differences in average attendance delays by age, gender or level of deprivation.

Conclusion

The asynchronous review clinic significantly reduced attendance delays across the hospital network, addressing pre-existing backlog for stable chronic eye diseases. The reduction appeared to be maintained after the initial backlog had been cleared.
