Genome-wide bioinformatics analysis of the <i>MATE</i> gene family for abiotic stress tolerance in sunflower (<i>Helianthus annuus</i> L.)

by Mohammad Nazmol Hasan, Md. Robin Islam, Rafee Shahrier, Md. Bayazid Hossen

Abiotic stressors, such as drought, salinity, and heavy metals, induce physiological changes, nutritional imbalances, molecular alterations, and oxidative stress in plants, which significantly reduce productivity. However, the secondary transporters, multidrug and toxic compound extrusion (MATE) proteins, transport substrates and metabolites. Accordingly, in response to abiotic stressors, these proteins strengthen plants’ immune systems, detoxify toxins, and enhance growth and development. Although the roles of MATE proteins responding to abiotic stresses have been investigated in several plants, their functions in sunflower have not yet been discovered. Therefore, this study identified 74 MATE proteins in sunflower (HanMATE) based on phylogenetic analysis, which were distributed into four subgroups. Their MATE-like properties were then validated using the domain, motif, gene structure, gene duplication, and physicochemical analysis. The HanMATE proteins in various cell organelles play a crucial role in abiotic stress tolerance, scavenging reactive oxygen species (ROS), and regulating transcription. Subsequently, Most HanMATE genes are enriched with biological processes and molecular functions that transport micro- and macro-molecules, drugs, negatively charged ions, organic anions, and citrate. The important Cis-regulatory elements (CREs), abscisic acid-, light-, and MeJA-responsive elements in HanMATE genes regulate plants’ growth and development in stress conditions. The synteny analysis indicated that 41 HanMATE proteins exhibit over 75% sequence similarity with 40 established stress-responsive (SR) MATE proteins from various plant species, suggesting their potential SR characteristics. Furthermore, this study identified 136 microRNAs linked to 58 HanMATE proteins, including 19 major hub microRNAs and 31 hub HanMATE proteins, which may enhance sunflower agronomic traits and abiotic stress resistance. The HanMATE proteins are conserved in other species that contribute to detoxification and have stable binding affinity with flavonoids and citric acid, validated from 3D structural modeling, molecular docking (MD), dynamic simulation, and functional prediction. These findings demonstrate that HanMATE genes are essential for sunflower abiotic stress tolerance (AST), and genetic engineering can be applied to develop more robust sunflower.

Por: Saberian · S. · Gallagher · N. · Maden · M. · Maudsley · G. · Esan · O. B. · Djoumessi Tonle · S. · Madden · M. · Gale · C. · Subhedar · N. · Sinha · I. · Schlüter · D. K. · Taylor-Robinson · D.
Introduction

Socioeconomic inequalities in neonatal mortality are observed globally but gaps remain in the evidence from current reviews, specifically: a wider range of socioeconomic indicators at the individual, household and area level than previous reviews, and alternative time frames to define neonatal mortality. Thus, a comprehensive updated review of the literature is required, focusing on multiple measures of socioeconomic status and alternative time frames, to assess the relationship between maternal socioeconomic status and neonatal mortality in high-income countries.

Methods and analysis

Three different search approaches will be used: electronic searching of three databases, grey literature searching and reference list checking. First, the three databases Medline, Scopus and Web of Science will be searched using relevant synonyms and adapted terms from medical subject heading terms (MeSH) in Medline for maternal socioeconomic status and neonatal mortality identified from previous systematic reviews on inequalities in adverse pregnancy outcomes. Second, grey literature will be searched by entering the relevant terms into Google. Title, abstract and full text screening will be conducted by the review team against the inclusion and exclusion criteria, with at least 10% checked by a second reviewer to assess for any bias and errors. We will also conduct the kappa statistic for inter-rater reliability. Third, the reference lists of included studies will be reviewed for any additional studies that meet the criteria. Data will be extracted using a data extraction form and extracted studies will be assessed using the Liverpool Quality Assessment Tool. A narrative synthesis will be conducted and, where appropriate, meta-analysis will be performed. If the data allow, subgroup analysis by neonatal care population and specific gestational ages will be performed.

Ethics and dissemination

Ethical approval is not required as all studies in this systematic review will be publicly available. The findings of this review will be presented at conferences and disseminated in peer-reviewed publications.

‘Fend for yourself’: Nurses’ experiences transitioning to Family Care Team practice settings in Newfoundland and Labrador

by Robin Devey-Burry, Julia Lukewich, Dana Ryan, Myuri Sivanthan, Maria Mathews, Marie-Eve Poitras, Cheryl Etchegary, Shabnam Asghari, Margot Antle

Background

Family Care Teams were introduced in Newfoundland and Labrador (NL) as a strategy to strengthen primary care through team-based models that optimize interprofessional collaboration. Nurses, including nurse practitioners (NPs), registered nurses (RNs), and licensed practical nurses (LPNs), play critical roles in these models; however, little is known about nurses’ transition to these settings or the supports shaping their integration and effectiveness. To address this gap, we explored nurses’ experiences transitioning into Family Care Teams, including supports for integration and the barriers and facilitators influencing this process.

Methods

As part of a qualitative descriptive study, we conducted semi-structured interviews with 25 nurses (6 NPs, 13 RNs, 6 LPNs) employed in Family Care Teams across five NL health zones. During the interviews, nurses described their experiences working in Family Care Teams, available practice supports, current roles, and barriers and facilitators to maximizing scope of practice. Interviews were transcribed and analyzed using qualitative content analysis and constant comparison.

Results

Participants described their transition to Family Care Teams in two stages: 1) orientation and 2) supportive learning relationships. Orientation was highly variable, ranging in length and structure. Learning in this area was often self-directed, technology-focused, and asynchronous, with limited emphasis on clinical preparation or role expectations. Mentorship and shadowing opportunities were inconsistently available, with many nurses lacking access to experienced role models within the newly established teams. These gaps contributed to role ambiguity, underutilization of nursing scope of practice, and prolonged adjustment periods.

Conclusions

Our findings reveal gaps in orientation and mentorship during nurses’ transition into Family Care Teams in NL. A common yet adaptable transition framework, expanded student placements, and structured mentorship are critical to optimizing nursing roles in team-based care. Strengthening practice supports and clarifying nursing contributions can improve access and care quality while informing broader initiatives to support nurses’ transition into primary care.

Key Features of Successful Research‐Related Roles for Nurses and Midwives in out of Hospital Settings: A Mixed Methods Approach

ABSTRACT

Aim

To explore the views of health care professionals involved in initiatives that have led to successful research-related roles for nurses and midwives working in community settings.

Design

A sequential mixed-methods study.

Methods

Between December 2022 and January 2023 a survey was completed by health care professionals with relevant experience of successful research-related initiatives for nurses and midwives in community settings. Survey responses were categorised into low, medium or high-priority examples of productive practice. Nineteen of the twenty responders who provided high-priority examples were interviewed between May and July 2023. The research capacity development for impact framework underpinned data collection and analysis. Data were thematically analysed using the framework method.

Results

The seven themes of the research capacity development for impact framework: leadership and sustainability, skills and confidence building, infrastructures, linkages and collaborations, ownership and responsibilities, actionable dissemination and co-production were identified as important features of successful research-related roles in community settings. A new cross-cutting theme of trust and relationships was generated. The initiation, continued growth and ambition continuum guided the development of the planning change and features of success template.

Conclusion

This study highlighted the key features that matter when planning change and developing research-related roles for nurses and midwives in community settings.

Impact

Study findings have the potential to inform policy and practice for organisations focused on developing research capacity and capability in community settings.

Reporting Method

This study adhered to the COREQ reporting guidelines.

Methodological review of the design, objectives and sample size of Research for Patient Benefit (RfPB) applications that use an external randomised controlled pilot trial design: A protocol

by Claire L. Chan, Saskia Eddy, Jennie Hejdenberg, Ben Morgan, Heather M. Morgan, Gillian Lancaster, Clare Robinson, Sandra M. Eldridge

Background

The 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.

Methods

The 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.

Discussion

This 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.

Protocol of the RADIO-STAR trial: a phase 1 safety and dose finding study of hypofractionated radiotherapy to the stellate ganglia for the treatment of ventricular arrhythmia

Por: Bussmann · B. M. · George · B. · Robinson · M. · Grist · J. · Sukumar · P. · Chinherende · E. · Sheerin · F. · Enzhil · V. · Rider · O. · Jones · B. · Sabharwal · A. · Herring · N.
Introduction

Sympathetic activation is the hallmark of cardiac disease, driving disease progression and triggering ventricular arrhythmia (VA). Despite optimal medical therapy, many patients experience recurrent VAs refractory to medical therapy, leading to repetitive implantable cardioverter defibrillator (ICD) therapy, worse quality of life and adverse outcomes. Cardiac sympathetic denervation (CSD) through surgical removal of the stellate ganglia is an effective treatment for refractory VAs but carries a high complication rate. We hypothesise that high precision image guided radiotherapy can be used to target the stellate ganglia to achieve CSD non-invasively.

Methods and analysis

RADIO-STAR (hypofractionated radiotherapy to the stellate ganglia for ventricular arrhythmia) is a first-in-human, phase 1 safety and dose finding study of radiotherapy to the stellate ganglia in patients with recurrent VAs. Patients with structural heart disease requiring recurrent ICD therapy for VAs are invited to undergo radiotherapy bilaterally to their stellate ganglia with a predetermined sample size of n=13. Radiotherapy dose will be determined by a prespecified dose escalation protocol. The primary outcome is safety defined as any treatment-related grade 3–5 toxicity occurring within 6 months of radiotherapy treatment, as defined by the Common Terminology Criteria for Adverse Events or any treatment-related side effects detected on patient symptom questionnaires and clinical examination during study visits. Secondary outcome measures to evaluate feasibility and efficacy include ability to safely deliver radiotherapy and consequent changes in circulating catecholamines and neuropeptide-Y, heart rate variability, structural changes in the stellate ganglia on MRI imaging and ICD therapy burden.

Ethics and dissemination

This study has received ethical approval by the South Central—Oxford B Research Ethics Committee (REC/SC/0005). Study findings will be submitted for publication in peer-reviewed scientific journals and presented at national and/or international scientific conferences.

Patiromer utility as an adjunct treatment in patients needing urgent hyperkalaemia management (PLATINUM): a randomised controlled trial in the emergency department

Por: Rafique · Z. · Safdar · B. · Duanmu · Y. · Boone · S. · Meltzer · A. · Bischof · J. J. · Robinson · D. · Budden · J. · Budd · J. · Quinn · C. M. · Milliet · C. · Singer · A. J. · Soto · K. · Peacock · F.
Objectives

Hyperkalaemia (HK) is common in the emergency department (ED) and can cause life-threatening arrhythmias. Patiromer is a potassium binder whose role in acute HK management is uncertain; therefore, we investigated the efficacy and safety of patiromer as an adjunct to the standard of care treatment of HK in the ED.

Design

A prospective, randomised, double-blind, placebo-controlled study.

Setting

16 ED sites across the USA.

Participants

Patients aged ≥18 years treated at a participating ED who were found to have serum potassium ≥5.8 mEq/L.

Interventions

Participants were randomised 1:1 to standard combination therapy (25 g intravenous dextrose, 5 units intravenous insulin and 10 mg albuterol) with either patiromer or placebo. The initial dose was given within 1 hour of the potassium result, and the second dose 24 hours later.

Primary and secondary outcome measures

The primary endpoint was net clinical benefit (NCB) at 6 hours, defined as the change in number of potassium-lowering interventions minus change in serum potassium. Adverse events (AEs) were also recorded.

Results

The study was terminated early and did not reach the prespecified sample size. Overall, 111 patients (53 patiromer and 58 placebo) were analysed. Mean (SD) age was 61.34 (15.21) years, 34% were female, 48% white and 22.5% received chronic haemodialysis. Mean baseline potassium was 6.5 mmol/L. NCB at 6 hours was similar between patiromer and placebo (–0.6 vs –0.4; p=0.44). Potassium levels at 2, 4 and 6 hours were similar between the groups (5.50 vs 5.70, 5.45 vs 5.65, 5.50 vs 5.60; patiromer and placebo (all p>0.05)). The number of interventions per patient was similar (p>0.05) between groups at each time point. The proportion of patients experiencing AEs was not significant between the patiromer and placebo groups (16.98% vs 32.76%; p=0.08).

Conclusions

No differences in efficacy were reported in this study, which was underpowered to detect statistical efficacy of patiromer over placebo.

Por: Hudson · B. F. · Ashcroft · P. · Bedford · J. · Bush · J. · Bowers · B. · Dawson · A. · Hussain · J. · Holmes · S. · Kumar · R. · Minton · O. · McCullagh · A. · Nicoll · L. · Penny · A. · Rabbitte · M. · Reece · A. · Robinson · D. · Simpson-Greene · C. · Taylor · M. · Best · S. L.
Background

Palliative care supports the physical, emotional, social and spiritual needs of people with serious life-limiting illness. Future research must align with the priorities of people approaching the end of their lives, and those close to them.

Aims

To undertake a refresh of the James Lind Alliance Palliative and End of Life Care Priority Setting Partnership, to identify and prioritise areas for future research.

Design

The James Lind Alliance process was applied, between May 2023 and February 2025. An initial online survey collected areas for future research from participants. These were synthesised into a long list of questions and shortlisted through a second online survey. Final ranking of priorities was achieved using an adapted Nominal Group Technique within a prioritisation workshop.

Participants

People living with serious life-limiting illnesses, carers, friends and family members supporting them, bereaved people, health and social care professionals, volunteers working in palliative and end-of-life care and members of the public.

Results

1032 and 626 responses were received to survey 1 and 2, respectively. 20 people with lived and professional experience attended the prioritisation workshop. An updated list of 24 priorities for palliative and end-of-life care research was produced.

Conclusion

The priorities reflect the range of issues shaping end-of-life experiences and serve as a call to action for researchers and funders.

Dementia and Mild Cognitive Impairment in Prison (DECISION) care pathway and training package: protocol for a realist-informed mixed-methods feasibility study

Por: Forsyth · K. · Buck · D. · Stalker · K. · Allgar · V. · Shaw · J. · Cowley-Sharp · R. · Hunter · R. · Lennox · C. · ONeill · A. · Robinson · C. · Ware · S. · Robinson · L.
Introduction

Recent research indicates that around 8% of older people living in prison have signs or symptoms of dementia or mild cognitive impairment (MCI), yet the care they receive is not equivalent to care in the community and this means their needs may not be met. We co-developed an intervention specifically for older people living in prison with dementia/MCI (Dementia and Mild Cognitive Impairment in prison care pathway and training package–DECISION). To date, this has not been implemented or evaluated. This paper presents our protocol for a study to assess the feasibility and acceptability of DECISION.

Methods

This is a non-randomised, realist-informed mixed-methods feasibility study with integrated process evaluation, which will take place in two prisons in England. The intervention was codeveloped with experts with lived experience. Participants will include older people living in prison, staff working in prison and peer supporters. We will assess the feasibility and acceptability of the intervention (eg, numbers eligible; rates of recruitment and retention), and the evaluation design (eg, completion rates of standardised outcome measures). Methods will include semistructured, realist-informed interviews; an audit to assess implementation fidelity; focused ethnography; training questionnaires; and collection of resource use data. We will refine the DECISION programme theory using realist-informed methods to examine and refine how contexts and mechanisms interact to produce the intervention’s outcomes.

Ethics and dissemination

This study received a favourable ethical opinion from the Wales REC 3 Research Ethics Committee in January 2025 (reference number 24/WA/0323). HMPPS National Research Committee approval was also granted in January 2025 (reference number 2024-1451). Findings will be disseminated through a range of avenues, including stakeholder engagement events, open-access papers, conference presentations, evidence briefings for commissioners, providers and practitioners, and newsletters for service users.

Adjunctive Tongxinluo capsule for patients with acute coronary syndromes undergoing percutaneous coronary intervention: a GRADE-assessed systematic review and meta-analysis of randomised controlled trials

Por: Liang · S.-B. · Wang · Y.-F. · Li · Y.-F. · Chen · W.-J. · Zhu · Y.-S. · Hua · Z. · Zheng · H.-M. · Niu · Z.-C. · Robinson · N. · Liu · J.-P. · Li · Y.-L.
Background

Tongxinluo capsule (TXL) is widely used in China as an adjunctive therapy for patients with acute coronary syndromes (ACS) who underwent percutaneous coronary intervention (PCI), collectively referred to as ACS-PCI. However, current evidence on its therapeutic effects and safety remains limited and insufficiently synthesised. This review aims to evaluate the therapeutic effects and safety of adding TXL to Western medical therapy (WM) in this population.

Methods

A systematic literature search was performed in PubMed, the Cochrane Library, CNKI, VIP and Wanfang from inception to August 2024; a rapid supplemental search was conducted up to November 2025, without language restrictions, to identify randomised controlled trials (RCTs) evaluating the therapeutic effects and safety of adding TXL to WM in patients with ACS-PCI. Dichotomous outcomes were summarised using risk ratios (RRs) with 95% CIs; absolute risk reductions (ARRs) were estimated as risk differences, and corresponding numbers needed to treat (NNTs) were calculated. Continuous outcomes were summarised using mean differences (MDs) with 95% CIs. All meta-analyses were performed using a random-effects model. The included studies generally had limitations in methodological quality, heterogeneity across analyses was low to moderate and the potential for publication bias could not be excluded. The evidence certainty for each outcome was assessed using the Grading of Recommendations Assessment, Development and Evaluation approach.

Results

Eighteen RCTs involving 1800 participants were included. Low-certainty evidence indicated that adding TXL to WM may reduce the risks of restenosis (RR=0.30, 95% CI 0.10 to 0.91; ARR=0.056, NNT=18), revascularisation (RR=0.28, 95% CI 0.10 to 0.80; ARR=0.069, NNT=15), myocardial infarction (RR=0.44, 95% CI 0.20 to 0.98; ARR=0.033, NNT=31), angina (RR=0.32, 95% CI 0.17 to 0.61; ARR=0.076, NNT=14) and other cardiovascular events (RR=0.41, 95% CI 0.24 to 0.71; ARR=0.075, NNT=14). It also improved Seattle Angina Questionnaire scores (MD=8.82, 95% CI 6.58 to 11.05) and quality of life (qualitative synthesis). However, no statistically significant reductions were observed for sudden cardiac death (RR=0.39, 95% CI 0.12 to 1.27; ARR=0.022, NNT=45), or non-cardiovascular adverse events (RR=0.67, 95% CI 0.32 to 1.40; ARR=0.043, NNT=24) when TXL was added to WM.

Conclusion

Current evidence suggests that adjunctive TXL may reduce key cardiovascular events and improve symptoms and quality of life in patients with ACS-PCI, without increasing the risk of non-cardiovascular adverse events. However, all findings are based on low-certainty evidence. These results provide preliminary support for the use of TXL as an adjunctive therapy, but high-quality, multicentre RCTs are needed to confirm these effects and inform clinical guidelines.

Qualitative exploration of consumers experiences and perceptions of telehealth for allied health services in Australia

Por: Senyel · D. · Frith · M. · Burnard · K. · Coughlan · A. · Savira · F. · Norman · R. · Robinson · S. · Boyd · J.
Introduction

The COVID-19 pandemic accelerated telehealth adoption, offering remote consultations via phone and video. Allied health services are one part of the healthcare system where telehealth, in specific teleconsultations, has been applied and has shown promising results in improving healthcare access by breaking down financial, logistical and geographic barriers. However, more insight is needed into the consumer’s perspective. A consumer is anyone who has used, currently uses or will use telehealth for allied health services. Therefore, this study explores consumer experiences and preferences, identifying barriers and facilitators to telehealth for allied health services.

Methods

This qualitative study used focus group discussions to evaluate consumers’ experiences with telehealth for allied health services. Allied health was defined as healthcare professionals distinct from medical, dental and nursing fields. Eight focus groups with 57 participants were conducted. The participants were recruited from the general public as well as seldom represented communities such as a support service focused on improving and maintaining members’ mental health, the deaf and hard-of-hearing community, young disabled people and the Pacific Islander community. An inductive thematic analysis was used to analyse the data.

Results

Five main themes were identified. First, the consumer with their individual characteristics and context played a major role in the suitability of telehealth. Second, the allied health practitioner and their skills influenced the quality and therefore the success of remote consultations. Further, the relationship between consumer and practitioner contributed to the success of telehealth. The appointment itself was equally often discussed. While telehealth improved access to care, remote appointments were seen as more suitable for questions and verbal exchanges. Lastly, the technology was an important factor with the availability of necessary technology and the accessibility of it playing a central role.

Conclusions

The findings reinforce existing research while highlighting new insights from often under-represented groups, emphasising the importance of telehealth choice, accessible technology and quality standards.

Inequitably harmed: a scoping review protocol on patient safety and diverse population groups

Por: Ocloo · J. · Surendran · S. · Robin · B. · Noel · L. · Gibson · J. · Dawson · S.
Introduction

Patient safety is a central pillar of healthcare quality. However, with repeated examples of failure emerging across healthcare, there is an ongoing need to better understand how the safety of care can be improved for patients. Evidence suggests that some population groups are more likely to inequitably experience healthcare harm. This review will look at what evidence exists on understanding patient safety harm and its causes and impact on different population groups and particularly those from marginalised backgrounds. It will also focus on what actions can be taken to address patient safety disparities and service improvements, including with patient and public involvement.

Methods and analysis

A scoping review of empirical and grey literature will be conducted following the Joanna Briggs Institute guidance. Medical databases such as Medline, EMBASE, PsycINFO will be searched for peer-reviewed articles and grey literature sources such as BASE, institutional and government repositories will be searched for reports, independent reviews, confidential enquiries, etc. These will be searched from 2001 to present for publications in English. Title and abstract and full text screening will be undertaken by one or more people acting as first reviewers and validated by a second reviewer. A data extraction form will be used to extract data including equity considerations following the PRO EDI framework. Data will be grouped thematically and analysed using a narrative approach.

Ethics and dissemination

Ethics approval is not required for this work as the information used is publicly available. The findings of the review will be disseminated through stakeholder meetings, a peer-reviewed publication and conference presentations.

'This level of racism has always been there: clinicians views on supporting racially minoritised university students - a qualitative study in student support services in North East England

Por: Yeebo · M. F. · Kunorubwe · T. · Robinson · L. · Thwaites · S.
Objectives

To explore the experiences of clinicians providing pastoral and mental health services to racially and ethnically minoritised students (REMS) at UK universities, aiming to understand the challenges REMS face in accessing support and to identify ways to improve service inclusivity.

Design

Qualitative study using semi-structured interviews.

Setting

Student health and well-being services at five universities in the North East of England, a region with comparatively low racial diversity.

Participants

Ten clinicians (nine female, one male; nine White British, one other ethnic background; mean age 42.8 years) working in therapeutic roles with experience supporting REMS. Participants were recruited via opportunity sampling.

Methods

Semi-structured interviews, averaging 44 min, were video-recorded, transcribed verbatim and analysed using thematic analysis to identify key themes.

Results

Six overarching themes were identified: (1) the chokehold of layered systemic challenges, (2) dynamics of power, (3) lack of safety for REMS, (4) "Am I really getting it?", (5) psychological therapies for white people by white people and (6) the thirst for expertise. Clinicians were enthusiastic about providing culturally responsive care but reported limited access to reflective spaces and training. Contextual factors—including racism, Brexit and the marketisation of higher education—were perceived to affect service delivery and REMS’ engagement with mental health support. Business-model approaches to service provision were sources of frustration.

Conclusions

Clinicians face structural and systemic challenges in providing culturally sensitive mental health support to REMS. Enhancing staff training, reflective practice and service adaptation may improve access and efficacy. Findings offer practical insights for universities aiming to strengthen equity in student mental health services, and future work could evaluate interventions to increase clinician preparedness and REMS engagement.

Drug-related stigma among people who inject drugs – development and validation of the drug use stigma scale (DUSS)

by Robin A. Pollini, Catherine E. Paquette, Brandon Irvin, Jennifer L. Syvertsen, Christa L. Lilly

Drug use is a highly stigmatized behavior, and drug-related stigma is a key driver of behavioral risk, lower health care utilization, and associated adverse health outcomes among people who inject drugs (PWID). While instruments exist for measuring drug-related stigma, their applicability to community-based PWID across multiple stigma types (enacted, anticipated, internalized) and settings (health care, society, family) is limited, as most were developed using treatment-based samples and all were developed in urban populations. This study sought to develop a Drug Use Stigma Scale (DUSS) that addresses these limitations. We developed an initial list of 39 items based on literature review and qualitative interviews (N = 27) and three focus groups (N = 28) with PWID recruited from syringe services programs and via peer referral in two predominantly rural West Virginia counties. The scale items were administered in a survey to 336 PWID recruited from the same two counties divided into development and validation samples. Responses to the 39-item scale went through a multidimensional refinement process, including examination of internal consistency, Confirmatory Factor Analysis (CFA), and a three-factor CFA based on stigma setting. Next, a set of final measurement CFAs were conducted. Finally, the resulting scale was examined for criterion-related concurrent validation. The final DUSS consisted of 16 items with excellent fit statistics for the development sample: SRMR: 0.03, RMSEA: 0.09, GFI: 0.92, CFI: 0.96, NFI: 0.94. Fit attenuated but remained satisfactory for the validation sample. DUSS scores were significantly associated with increased odds of not seeking healthcare when needed (OR: 1.47, p = 0.001; OR: 1.61, p 

Economic evaluation of a hospital-initiated tobacco dependence treatment service

Objectives

The treatment of tobacco dependence in patients admitted to hospital is a priority for the National Health Service in England. We aimed to conduct an economic analysis of a pilot ‘opt-out’ tobacco dependence treatment intervention adapted from the Ottawa Model of Smoking Cessation.

Design

Observational cost analysis of an inpatient tobacco dependence treatment intervention, and matched cohort study comparing readmission costs between patients who received the intervention and benchmarked equivalents who did not.

Setting

11 acute inpatient wards in a major teaching hospital in London, England.

Participants

673 patients who smoked, admitted between 1 July 2020 and 30 June 2021.

Interventions

The intervention consisted of the systematic identification of smoking status, automatic referral to tobacco dependence advisors, provision of pharmacotherapy and behavioural support throughout the hospital stay and telephone support for 6 months after discharge.

Primary and secondary outcome measures

The primary outcomes were cost-per-patient, cost-per-quit and incremental cost effectiveness ratio among patients who received the intervention. The secondary outcomes were patient-level readmission costs and bed-days from 6 months after discharge, compared between the intervention group and a group of matched benchmark patients who smoked but did not receive the intervention.

Results

The total cost of the intervention was £178 105. On the basis of 104 patients who reported not smoking at 6 months, the cost-per-quit was £1712.55, equating to an estimated age-adjusted incremental cost per life year gained of £3325. Among 611 patients who were successfully matched to a benchmark cohort, readmissions for patients in the intervention group cost £492 k less than their benchmark equivalents over 21 months from 1 January 2021 to 30 September 2022 (£266 k vs £758 k), incurred 414 fewer bed days (303 vs 717) and readmitted at a lower rate (5% vs 11%). There were reduced readmission rates and costs among all patients who received the intervention compared with their benchmarked equivalents, regardless of smoking status at 6 months, except among those who opted out.

Conclusions

A pilot ‘opt-out’ tobacco dependence treatment intervention implemented in an acute hospital setting in London demonstrated value for money through reduced readmission rates and costs among all patients who received it.

Objective

To determine age-specific and age-standardised incidence trends of acute rheumatic fever (ARF) or rheumatic heart disease (RHD) among Indigenous Western Australians aged less than 35 years of age.

Design

A population-based retrospective cohort study with linked data analysis.

Setting

Western Australian hospital admissions (1996–2022) and RHD notifications to the state-based register (2011–2015).

Participants

Patients, both Indigenous and non-Indigenous aged

Results

Of 1746 incident ARF/RHD cases, 1526 (87%) were Indigenous peoples, with the highest rates observed in patients aged 5–14 years, with an annual estimated increase of 4.3% (95% CI 3.2% to 5.2%). The 0–4 years age group experienced an annual increase in incidence rates of 4.8% (95% CI 1.4% to 8.2%). Overall, Indigenous patients experienced an annual increase of 1.9% (95% CI 1.3% to 2.6%) from 1996 to 2022. However, most cases (n=894) were identified after multiple significant policy developments (2011–2022) with an annual increase of 5.7% (95% CI 3.7% to 7.5%) for this period.

Conclusion

Increasing trends of incident ARF/RHD were observed in Indigenous patients aged under 15 years, with the greatest annual increments observed after policy implementation for disease reporting and awareness in the period from 2011 to 2022. Improvement in case ascertainment of ARF/RHD may be contributing towards increasing trends with improved reporting and monitoring of incident cases in very young Indigenous Australians more recently.

Introduction

Streptococcus pneumoniae serotype 3 (SPN3) remains a significant contributor to invasive pneumococcal disease globally, despite its inclusion in widely administered vaccines. The next generation of pneumococcal vaccines may confer better protection against this serotype, reducing disease burden. We describe an ethically approved protocol for a double-blind randomised controlled trial assessing the impact of VAXNEUVANCE (15-valent pneumococcal conjugated vaccine (PCV15)) and 0.9% saline (placebo) on the acquisition, density and duration of SPN3 carriage using a controlled human infection model.

Methods and analysis

Healthy adults aged 18–50 years will be randomised 1:1 to receive PCV15 or placebo. Participants will be considered enrolled on the trial at vaccination. One month following vaccination, all participants will be intranasally inoculated with SPN3. Following inoculation, participants will be followed up on days 2, 7, 14 and 28 to monitor safety, SPN3 colonisation status, density and duration, as well as immune responses. The primary endpoint of the study is to assess the rate of SPN3 acquisition between vaccinated and unvaccinated participants defined by classical microbiological methods. Secondary endpoints will determine the density and duration of SPN3 colonisation and compare the immune responses between study groups. An exploratory cohort of 5 participants will be asked to consent to a nasal biopsy procedure during a screening visit and a second nasal biopsy 28 days after PCV15 vaccination. This cohort will only receive PCV15 and will not be challenged. Through this exploratory cohort, we will explore gene expression changes induced by PCV15 vaccination and their visualisation (spatial location) within the nasal tissue.

Ethics and dissemination

This protocol has been reviewed by the sponsor, funder and external peer reviewers. The study is approved by the NHS Research and Ethics Committee (Reference: 24/SC/0388) and by the Medicines and Healthcare Products Regulatory Agency (Reference: CTA 21584/0485/001-0001).

Sociodemographic and geographical variation in prescribing psychotropic drugs to children and young people with common mental disorders and Attention Deficit Hyperactive Disorders in North West London: population-based study

Objectives

To estimate the sociodemographic and geographical variation in prescribing selective serotonin reuptake inhibitors (SSRIs) and medications for attention-deficit/hyperactivity disorder (ADHD) to children and young people (CYP) in North West London, UK.

Design

Cross-sectional population-based study.

Setting

General practices in North West London, UK, with data for the period 2020–2022 obtained from the Discover Now platform, which covers approximately 95% of the local population.

Participants

762 390 CYP aged 5–24 years in the year 2022.

Primary and secondary outcome measures

Primary outcome: Prescription rates of SSRIs and ADHD medications. Secondary outcomes: Associations between prescription rates and sociodemographic factors, including age, gender, geographical area (local authority), ethnicity and socioeconomic deprivation (measured using the Index of Multiple Deprivation).

Results

The total sample comprised 762 390 CYP. 2.20% of the sample were prescribed an SSRI (95% CI 2.17% to 2.24%) and 0.50% an ADHD medication (95% CI 0.49% to 0.52%) in years 2020–2022. High deprivation was associated with the highest rates of an SSRI prescription (2.5%). In contrast, low deprivation was associated with the highest rates of an ADHD medication prescription (0.70%). This divergent pattern was evident in some London boroughs and not in others. The relationship between level of area deprivation and prescription rates also differed by borough. Overall, the sociodemographic factors could not explain most of the variation in prescription rates (Pseudo R2 0.18 for SSRI and 0.06 for an ADHD medication).

Conclusions

Prescriptions for common mental disorders and ADHD for CYP from North West London varied by sociodemographic characteristics and London borough of residence, potentially exacerbating mental health inequalities. To monitor and address these inequalities, more extensive use of linked electronic health records should be undertaken; for example, data on mental health diagnosis and service utilisation are needed to investigate the relationship between diagnosis and treatment over time.

'Small Steps towards improving 24-hour time-use behaviours to decrease the risk of dementia: protocol for a personalised, web-based randomised controlled trial in community-dwelling older adults

Introduction

Addressing physical inactivity is a promising dementia risk reduction strategy due to its direct benefits for brain health, and indirect benefits for other modifiable dementia risk factors. A potential limitation of previous interventions is that they often overlook how increasing physical activity affects other behaviours throughout the 24-hour day, such as sleep and sedentary behaviour, which are also important for brain health. Further, interventions are rarely tailored to the individual, considering their needs, preferences and constraints that may serve as barriers or facilitators to behaviour change. The current phase I randomised controlled trial, Small Steps, aims to investigate feasibility, acceptability and preliminary effectiveness of a personalised 24-hour time-use intervention to improve lifestyle and cognitive health in older adults.

Methods and analysis

Participants aged ≥65 years from Adelaide, South Australia will be recruited and randomised to either the Extended or Condensed programme. During the first 12 weeks, participants in the Extended programme will use a tailored website to set personalised weekly goals to move towards their ‘optimal’ 24-hour day for brain health, facilitated by weekly website ‘check-ins’ and weekly phone calls with a research staff member. Participants randomised to the Condensed programme will have access to the website educational resources only but will not undergo personalised goal setting or telephone calls. Following the introductory phase (first 12 weeks), phone calls will be gradually withdrawn for the Extended programme. Primary (feasibility and acceptability) and secondary outcomes (changes in time use, cognitive function and behaviour change metrics) will be assessed 12, 24 and 36 weeks after the beginning of the intervention.

Ethics and dissemination

Ethics approval has been obtained from the University of South Australia’s Human Research Ethics Committee (205989). Study findings will be disseminated through peer-reviewed journal articles, conference presentations, media releases and community engagement.
