The roles of pharmacy staff have expanded to include public health functions, such as delivering harm reduction services for people who use drugs (PWUD), particularly unregulated substances and non-medical drug use, in response to an ongoing drug overdose crisis. Nonetheless, their involvement across the full spectrum of harm reduction services remains underexplored. This study mapped existing research describing or evaluating the implementation of harm reduction services for PWUD provided by pharmacy staff.

Studies reporting on the description or evaluation of harm reduction services for PWUD provided by pharmacy staff.
Two team members screened studies for eligibility and extracted the data. The data were analysed primarily to describe harm reduction services and the role of pharmacy staff.
43 articles were included. The most frequently reported harm reduction services were sexually transmitted and blood-borne infection care (33%), needle and syringe programmes (21%), naloxone distribution (19%) and medication treatment for opioid use disorder (19%). Pharmacy staff were integrated into multidisciplinary teams (79%), with their roles varying from education to medication prescribing. Included studies reported harm reduction services for PWUD delivered by pharmacy staff as effective, feasible and safe. However, implementations were not tailored to equity-deserving populations. Services primarily addressed opioid-related harms, while strategies focusing on the use of non-opioid substances were limited.
This scoping review highlights the diverse roles pharmacy staff play in delivering harm reduction services for PWUD. Positioned at the intersection of accessibility and healthcare delivery, pharmacy staff are ideally situated to expand access to equitable care. To fully harness this potential, future research and practice should embed harm reduction as a core philosophy, extending beyond individual interventions to support the creation of person-centred, non-judgmental and low-barrier services.
To determine the prevalence and factors associated with pain-related disabilities among First Nations people living off-reserve in Canada in 2017.
Secondary analysis of the 2017 Aboriginal Peoples Survey, a cross-sectional survey of individuals living in private dwellings throughout Canada.
First Nations people living off-reserve aged 15 years and older (n=9115; weighted n=482 066).
Pain-related disabilities, defined as pain-related activity limitations lasting ≥6 months.
Overall, 22.1% (95% CI 20.9% to 23.4%) of First Nations people living off-reserve reported pain-related disabilities. Prevalence was higher among females (26.1%; 95% CI (24.3% to 28.0%)), increased with age (34.3%; 95% CI (30.3% to 38.5%) among those 45 to 54 years) and was similar across geographic areas (ranging from 21.0%; 95% CI (18.3% to 23.9%) to 22.5%; 95% CI (20.8% to 24.2%)). Pain-related disabilities increased with the number of coexisting disabilities (96.2%; 95% CI (94.3% to 97.5%) among those with >3 disabilities) and was highest among those reporting physical disabilities (ranging from 88.2%; 95% CI (85.6% to 90.4%) for those with mobility disabilities to 91.0%; 95% CI (88.6% to 92.9%) for those with disability related to flexibility). Regression models suggested that individuals with unmet basic needs, housing dissatisfaction, unmet healthcare needs, a history of mental health consultations, part-time or no employment, chronic conditions, residential school attendance or a low sense of belonging were more likely to report pain-related disabilities.
Pain-related disabilities are common among First Nations people living off-reserve, and their aetiology may be multifactorial. Continued collaboration with Indigenous partners is required to contextualise findings and to inform culturally responsive clinical and rehabilitation strategies.
Human papillomavirus (HPV) is a major contributor to several preventable cancers. Although the HPV vaccine is recognized by the Centers for Disease Control and Prevention (CDC) as safe and effective, uptake among U.S. adolescents remains below optimal levels. Disparities in vaccination rates are shaped by both individual characteristics and social determinants of health (SDOH).
To systematically review and synthesize the literature examining individual factors and social determinants of health associated with HPV vaccine initiation and completion among adolescents aged 9–18 years in the U.S.
A systematic search was conducted in accordance with PRISMA guidelines, yielding 37 eligible studies from an initial pool of 2092 articles. The STROBE checklist was used to assess methodological quality, and the Levels of Evidence framework by Melnyk and Fineout-Overholt guided appraisal of study strength.
Across included studies, initiation and completion rates averaged 47% and 40%, respectively. Key predictors of higher vaccine uptake included provider recommendation, health insurance coverage, urban residence, older age, and higher parental education. Disparities were most evident among adolescents living in rural areas and those from minority or low-income backgrounds. Barriers reported in several studies included parental safety concerns and logistical challenges. Evidence regarding parental knowledge and attitudes was mixed: smaller studies suggested an influence, whereas the largest population-based study reported no significant effect.
Addressing HPV vaccination disparities requires a multifaceted approach, including improving healthcare access in underserved regions, strengthening provider–parent communication, and implementing policy interventions such as school-based vaccination programs and state mandates. Normalizing HPV vaccination as part of routine adolescent care is essential for reducing HPV-related cancer morbidity and mortality. These findings also have implications for catch-up vaccination in young adults aged 15–26 and shared clinical decision-making up to age 45, which remain important strategies for increasing protection across the lifespan.
The Windrush Generation describes a group of individuals who migrated, primarily from the Caribbean to the UK between 1948 and 1971, many of whom are now entering older age. Now entering later life, many face ongoing health inequalities shaped by systemic racism and cultural marginalisation. Despite a growing number of ethnic minority residents in UK care homes, little is known about the lived experiences of Black African Caribbean people in these settings, particularly at the end of life.
This qualitative study explores the experiences of Black African Caribbean care home residents and their families, focusing on how race, identity and marginalisation shape care. Guided by the Silences Framework, semistructured interviews will be conducted with up to 16 participants across diverse care home settings. Data will be analysed thematically, with attention to under-represented narratives. A Patient and Public Involvement group of African Caribbean community members has codeveloped the study and will support analysis and dissemination to ensure cultural relevance.
Ethical approval has been secured (REC: 24/WM/0151; protocol number: RG_21087; IRAS project ID: 302629), and the study will follow rigorous consent and capacity procedures, including caregiver affirmation and UBACC assessment where needed. Given the sensitive, potentially distressing focus on racism, marginalisation and end-of-life experiences, the research will be conducted by an experienced clinician-researcher using a reflexive, ethically grounded approach that safeguards both participants and researcher. Interviews will be held in private, accessible settings with appropriate advocacy, safeguarding concerns will follow care home and national protocols, and all data will be securely stored, anonymised and managed under General Data Protection Regulation and university governance, with the University of Birmingham as sponsor and data controller.
To translate, culturally adapt and validate the first Spanish version of the Person-centred Practice Inventory-Care (PCPI-C) instrument.
Cross-cultural adaptation and psychometric validation.
Two-phase research design: (1) the PCPI-C's translation and cultural adaptation from English to Spanish following the ‘Translation and Cultural Adaptation of Patient-Reported Outcomes Measures-Principles Guide of Good Practice’ tool; and (2) a cross-sectional quantitative survey to assess the Spanish version's psychometric properties.
A sample of 200 patients participated to obtain the PCPI-C's Spanish version. No significant issues arose during the translation process or the consulting sessions. No item exhibited an inadequate value following adjustment via the weighted kappa index (−scale-level content validity average of 0.95 for clarity and 0.97 for relevance). Psychometric evaluation revealed acceptable internal consistency (Cronbach's alpha from 0.67 to 0.84) and strong construct validity. Exploratory and confirmatory factor analyses supported a five-dimensional structure consistent with the domain Person-Centred Processes. Fit indices improved after model refinements, achieving CFI = 0.92, SRMR = 0.05 and RMSEA = 0.07. This study's observed psychometric properties confirm that the PCPI-C's Spanish version retains the original instrument's theoretical integrity, while showing strong reliability and validity in the new context.
The PCPI-C's Spanish translation was psychometrically valid when tested with Spanish patients, thus providing a culturally appropriate, psychometrically sound tool to evaluate Spanish-speaking patients' perception of person-centred care.
This study provides a validated instrument that allows for the assessment of person-centred practice in Spanish-speaking clinical environments. It enables healthcare professionals to measure patients' perceptions, track the implementation of person-centred principles and supports international comparative studies, contributing to the development of more ethical and responsive models of care.
Patients participated in cognitive consultations and completed the survey for psychometric testing, ensuring that the translated items were understandable, culturally appropriate and reflective of their experiences of person-centred care.

Methotrexate (MTX) is used in treating several malignancies. However, MTX neurotoxicity remains a significant clinical side effect, leading to cell division malformation, and neurogenesis impairment. Chrysin, a flavonoid compound found in natural products, demonstrates various biological characteristics, including neuroprotective and antioxidant properties. The purpose of this study was to investigate the ameliorative effect of chrysin on oxidative damage and neurogenesis impairment caused by MTX. Male Sprague-Dawley rats were randomly divided into four groups, including the vehicle, MTX (75 mg/kg), chrysin (10 mg/kg), and chrysin+MTX groups. Chrysin was orally administered for 15 days. MTX was administered intravenously on days 8 and 15. The hippocampal neural stem cells were evaluated using sex determining region Y-box 2 (sox2) and nestin immunofluorescence staining. Antioxidant enzyme expression and the levels of oxidative stress marker were assessed. Additionally, the expressions of nuclear factor erythroid 2-related factor 2 (Nrf2), brain-derived neurotrophic factor (BDNF), cAMP-response element binding (CREB), and phosphorylated CREB (pCREB) were evaluated using Western blotting. Results showed that MTX significantly decreased the activity of antioxidant enzymes and produced oxidative stress. MTX also impaired neurogenesis, evidenced by decreased sox2 and nestin-positive cells and decreased expression of Nrf2, BDNF, CREB, and pCREB in the hippocampus and prefrontal cortex. However, chrysin significantly reversed the effects of MTX on these parameters. In conclusion, chrysin exhibits neuroprotective effects against MTX-induced neurogenesis impairment by upregulating antioxidant enzyme activity, reducing oxidative stress, and improving protein expression related to neurogenesis.The experiences of people from ethnic minority backgrounds living in care homes—A qualitative systematic review.
Despite the increasing need for older people from ethnic minority backgrounds to be able to access good quality, culturally competent care home provision, globally, there is an absence of literature exploring care home residents' perspectives. This study conducted a systematic review, identifying and synthesising qualitative evidence, which explored the experiences of residents', and their families, from ethnic minority backgrounds, who live in care home settings.
A qualitative systematic review.
Nine electronic databases, MEDLINE, Nursing and Allied Health, CINAHL, ASSIA, AMED, Sociological Abstracts, PsycINFO, Web of Science, SCOPUS, were systematically searched for research published after 2005 until 2025.
This systematic review of qualitative studies was conducted in accordance with The PRISMA 2020 (Preferred Reporting Items for Systematic Reviews and Meta-analyses) statement. Studies were appraised for quality based upon validated critical appraisal tools from the Joanna Briggs Institute. Qualitative data were extracted and synthesised using reflexive thematic analysis.
Sixteen studies were identified from the international literature that explored care home experiences from the resident's and families' perspectives. Three key themes were extrapolated: Patter, which includes how cross-cultural communication skills and language affect care experiences; Place, which includes the care home environment, the multi-ethnic environment, and quality of care; and Person, which encompasses the individual's culture, values, beliefs, food, and family.
There is limited literature from the UK and low-to-middle income countries exploring care home residents' perspectives on care provision. Key components of culturally competent care include culturally sensitive communication, adaptable environments that support residents' chosen lifestyles, and inclusive, family-centred approaches to living well.
For nurses within the adult social care sector, to recognise the need for further research, education, and policy initiatives aimed at enhancing the care home provision for people from ethnic minority groups.

A significant proportion of adults in England and Wales report experiencing childhood trauma, which is often associated with poor health and negative social outcomes including a significant increase in the risk of poor mental health outcomes in adulthood. This proposed scoping review adopts a broad definition of childhood trauma and applies both a salutogenic framework and ecological systems theory to explore how protective factors at five ecological levels can support mental well-being. The review will also examine how protective factors vary across different population groups and contexts.
The scoping review will follow the Joanna Briggs Institute (JBI) protocol for scoping reviews. The databases that will be searched are Embase, PubMed, Web of Science, PsycINFO, CINAHL and Medline. Studies will be included if they include protective factors and involve adults aged 18 and over who have experienced childhood trauma, whether self-identified, retrospectively self-reported or measured using a validated instrument. Studies will be excluded if they focus on participants under the age of 18.
All search results will be uploaded to Covidence, duplicates removed, and titles/abstracts screened by at least two reviewers based on inclusion criteria. Full texts of potentially relevant sources will be imported into EndNote 21. Reasons for exclusions will be documented and disagreements resolved through discussion or a third reviewer. The full process will be reported using a Preferred Reporting Items for Systematic Reviews and Meta-Analyses flow diagram. Data will be extracted by at least two reviewers using a tool developed by the team based on the JBI guidance. A best-fit framework analysis will be used, using a matrix developed by the researchers including the four salutogenic domains and the five levels of the ecological framework.
Formal ethical approval is not necessary for this scoping review as it does not involve the collection of primary data. The outcomes of this study will be disseminated through peer-reviewed journal articles, conference/seminar presentations, and developed into resources for stakeholders and collaborators.

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

AimThe underlying mechanisms contributing to cholestatic liver injury remain unclear. The pro-inflammatory leukocyte-restricted cytokine interleukin-17A (IL-17A) has been implicated in human cholestatic liver injury. However, mechanistic insights are lacking and require further exploration in preclinical models. Herein, we examined the effect of IL-17A genetic ablation in a mouse model of cholestatic liver injury.
MethodAge and gender-matched littermate wild type (WT) and Il-17a-/- C57BL/6 mice were fed an intermittent 0.1% 3,5-diethoxycarbonyl-1,4-dihydrocollidine (DDC) diet for 21 days to induce cholestatic liver injury or a control diet.
ResultsAs compared to WT littermates, Il-17a-/- mice displayed more abundant desmin-positive myofibroblasts and increased fibrosis. NanoString analysis of intrahepatic leukocyte populations using a fibrosis-related gene panel identified upregulation of Tnfsf14 (encoding the protein LIGHT) in the DDC-fed Il-17a-/- mice. Although mass cytometry identified an increase in myeloid cells in both genotypes of the DDC-fed mice, we could not identify LIGHT expression in this cell lineage. Instead, the upregulation of LIGHT expression was largely restricted to a CD4+ T cell population as assessed by flow cytometry. Enhanced LIGHT expression was observed in a Th1+ CD4+ T cell population. LIGHT activated primary human hepatic stellate cells in vitro, suggesting that LIGHT stimulation of hepatic fibrogenesis may be direct.
ConclusionTaken together, these data suggest that IL-17A restrains expression of the profibrogenic cytokine, LIGHT, by Th1-polarized CD4+ T cells, and implicate a role for LIGHT in cholestatic fibrogenesis in DDC-fed mice; a finding which requires validation in additional models.
The objective of this study is to co-produce a care bundle for women with multiple long-term health conditions (MLTC) that could be pilot tested and implemented in UK maternity services.
Online co-production workshops each attended by 20–30 key interest holders.
United Kingdom, October 2023-February 2024.
Women with experience of pregnancy with MLTC, healthcare professionals and other interest holders involved in commissioning, planning and delivering care for pregnant women with MLTC.
This study followed a three-step process: (1) a consolidated list of key components of care for pregnant women with MLTC was created through secondary analysis of prior collected qualitative data; (2) the list of care components was explored during four co-production workshops; and (3) findings from (1) and (2) were synthesised to develop a maternity care bundle of 4–5 key care components for pregnant women with MLTC.
A maternity care bundle of five key care components for pregnant women with MLTC.
A list of 25 care components was refined to develop a proposed care bundle of five components. These were provisions of early and reliable medication advice and decision support; creation of a ‘goals of care summary’ accessible to women and the care team; provision of continuity of midwifery care throughout pregnancy and postnatal care; provision of a named care coordinator; and a formal postnatal handover of care from the multidisciplinary care team to the General Practitioner (GP) and secondary care team involving the woman.
This study coproduced an evidence-based care bundle for pregnant women with MLTC to enhance communication and ensure individualised care and support. Further collaborative work with women and professionals is required to refine, implement and evaluate its impact on outcomes.
Inadequate production of the essential stress hormone, cortisol, results in adrenal insufficiency (AI), which is associated with significant morbidity and mortality. The current standard diagnostic test for AI is the Short Synacthen Test (SST), but this is both invasive and resource-intensive, involving cannulation and blood sampling. A novel formulation, Nasacthin, has been developed in which the same Active Pharmaceutical Ingredient can be delivered intranasally, with the resultant glucocorticoid levels either measured in serum, or in saliva samples to render the test non-invasive, thus creating a potentially more cost-effective test. The Salivary Test of Adrenal Response to Liquid Intranasal Tetracosactide (STARLIT-3) study aims to determine the diagnostic utility of the test in patients with AI.
STARLIT-3 is a randomised 2-way crossover trial which aims to collect data from 32 AI patients allocated to receive both Synacthen and Nasacthin in a random order across two study visits. Paired blood and saliva samples will be collected from participants at baseline, and then at 30 and 60 min after drug administration. Glucocorticoid levels in study samples will be quantified with the aim to determine whether the Nasacthin test is able to correctly diagnose patients with AI by estimating the positive percent agreement with the standard SST using serum cortisol at 30 and 60 min. Data on any reported harms and on the acceptability, usability and tolerability of the Nasacthin test will also be collected.
The study and subsequent amendments have been reviewed and approved by South Central—Hampshire A Research Ethics Committee. Results will be published in peer-reviewed journals and presented at national and international conferences. Plans for dissemination of results to trial participants will be developed in collaboration with patient and public involvement and engagement groups.
Poor sleep is common among patients with heart failure (HF) and is associated with adverse cardiovascular outcomes. The utility of actigraphy in sleep assessment, especially among older adults, remains underexplored. This study aimed to assess sleep health among older adults with HF using actigraphy and explore associations between sleep parameters and cardiac biomarkers, functional performance and quality of life (QoL).
A cross-sectional study.
The study was conducted at an outpatient HF clinic within a tertiary cardiology service in a National Health Service hospital in the UK between March and October 2023.
A total of 150 older adults aged ≥65 years with a diagnosis of HF were enrolled.
Participants were given a wrist-accelerometer to wear for 7 days. On Day 0, patients completed a 4-metre walk test (4MWT), handgrip strength test (HGST), Timed Up and Go test (TUGT), Barthel Index (BI), Kansas City Cardiomyopathy Questionnaire (KCCQ-12) and frailty assessment (Clinical Frailty Scale, CFS). Subsequently, they were fitted with an accelerometer, with the device configured to start recording the following day (Day 1). Sleep outcomes were calculated after a 7-day wear period and averaged across valid nights (minimum 3 nights of recording, noon-to-noon with ≥16 hours wear-time). Sleep parameters studied include average sleep efficiency, sleep period time window, sleep duration, sleep onset and wake up time, wake after sleep onset (WASO), sleep interruptions and Sleep Regularity Index (SRI). Inefficient sleep was defined as sleep efficiency
The primary outcome measure was sleep efficiency; all other sleep parameters were classified as secondary or exploratory outcomes.
Accelerometry data from 145 participants were analysed; 42% had inefficient sleep based on average sleep efficiency across valid nights. These patients had significantly higher plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels (p=0.044). No statistically significant difference was noted in 4MWT, HGST, TUGT, BI, KCCQ-12 and CFS between patients with sleep efficiency
Older adults with HF who had inefficient sleep had significantly higher NT-proBNP levels. Lower sleep efficiency was associated with higher functional dependence and frailty. Sleep irregularity was linked to HF symptom load, frailty, functional performance and QoL, while sleep fragmentation was associated with impaired gait speed.
To synthesise literature on hospital-based geriatric models of care for older adults undergoing surgery, examining structures, team composition, governance and nursing contributions.
Scoping review.
Following JBI methodology, two reviewers independently screened articles against eligibility criteria (Population: adults ≥ 65 years, Concept: multidisciplinary geriatric surgical care model; Context: acute hospital settings), with conflicts resolved by a third reviewer. Data were extracted and charted for descriptive synthesis.
Six databases (CINAHL, MEDLINE, Embase, Scopus, AgeLine, Cochrane Library) searched for studies published between January 2015 and February 2025.
Of 2753 records identified, 81 studies were included. Models were commonly co-managed between surgical and geriatric teams, implemented at varying surgical pathway points. Orthopaedics represented 57% of studies. Geriatricians were involved in 90% of models; 38% included advanced practice nurses or specialist gerontological nurses. Comprehensive Geriatric Assessment was used in nearly half the studies, typically preoperatively. Considerable heterogeneity existed in model design, professional roles and care settings.
Integrated geriatric perioperative care is expanding globally but remains limited outside orthopaedics. Research should shift from improvement projects to rigorous implementation for sustainable transformation, including nurse-led models. Critical examination is needed of whether current outcomes address comprehensive needs of older surgical patients or primarily optimise hospital flow.
Findings highlight opportunities to expand geriatric models beyond orthopaedics and enhance nursing roles, particularly advanced practice nurses, in delivering comprehensive perioperative care for older adults.
Addressed the gap in understanding how geriatric models of surgical care are operationalised. Identified underutilisation of nursing expertise and limited expansion beyond orthopaedics. Will impact service design, policy development and clinical implementation for older surgical patients.

To (1) examine the attitudes of community-dwelling adults towards death and their ability to cope with death, as well as (2) understand the influence of advance care planning on community-dwelling adults' death attitudes and coping with death.
A sequential explanatory mixed-methods study was conducted in Singapore.
In Phase I, a case–control study was conducted to examine the differences in death attitudes and coping with death ability between community-dwelling adults who have completed advance care planning and those who have not. A univariate general linear model was used to compute the mean difference in death attitudes and coping with death scores. In Phase II, a descriptive qualitative study was conducted to provide an in-depth understanding of the influence of advance care planning among community-dwelling adults. Thematic analysis was used for qualitative analysis. Mixed-methods analysis was conducted to integrate the quantitative and qualitative data.
In Phase I, 80 community-dwelling adults who had completed advance care planning and 81 community-dwelling adults who did not have advance care planning were included. Adults who had completed advance care planning had significantly higher coping with death scores (t = 4.14, p < 0.01). In Phase II, a purposive sample of 24 adults who had completed advance care planning was selected for individual semi-structured interviews. From the thematic analysis, three themes were developed: (1) Advance care planning enables coping with death, (2) overcoming fear of death with advance care planning and (3) confronting death with advance care planning.
Advance care planning may influence death attitudes and coping with death. Further work on longitudinal designs and among individuals from different age groups should be used to gain further in-depth understanding of the impacts of advance care planning.
Strategies to enhance one's coping abilities with death and death attitudes should be developed to stimulate the uptake of advance care planning.

BackgroundCtenocephalides felis is a common ectoparasite of dogs and cats and can transmit a variety of pathogens including Bartonella and Rickettsia species. These bacteria, along with the known endosymbiont Wolbachia, are well-documented members of the C. felis microbiome, but species-level information is limited. Additionally, little is known about the variation in the C. felis microbiome in fleas from different sources and when different sequencing methods are applied to the same samples.
ObjectiveThis study aimed to characterize the flea microbiome using both short-read (V3/V4) and long-read (full-length) 16S rRNA gene sequencing, determine whether long-read sequencing improves species-level identification especially in known pathogenic genera, and evaluate differences in microbial composition between fleas collected from cats, dogs, and environmental traps.
MethodsFleas were collected from cats, dogs, and traps in flea-infested homes in Florida, pooled by source, and sequenced using short- (V3/V4) and long-read (full-length) 16S rRNA gene sequencing. Microbial prevalence and abundance were compared across sequencing approaches. Community composition was evaluated for differences between sources and houses. Candidate members of the flea microbiome were identified based on a combination of prevalence, abundance, and statistical signatures of potential contaminant origin. For Rickettsia and Bartonella, species-level taxonomic assignments were refined using a phylogenetic approach.
ResultsWolbachia, Rickettsia, and Bartonella were the most prevalent and abundant taxa. Spiroplasma was identified as a fourth core member of the flea microbiome. Long-read sequencing enabled better, but not perfect, species-level classification of Bartonella and Rickettsia compared to short-read sequencing. Important relationships between specific ASVs and flea sources were identified, for example fleas from cats harbored higher abundances of B. clarridgeiae and B. henselae than fleas from traps.
Group A Streptococcus (Strep A) causes a wide spectrum of diseases, ranging from pharyngitis and impetigo to severe invasive infections and immune-mediated conditions such as acute rheumatic fever, rheumatic heart disease and acute post-streptococcal glomerulonephritis. Contemporary data on the global burden of Strep A diseases are lacking. The proposed study aims to use administrative data from numerous jurisdictions to estimate age-specific incidence or prevalence of Strep A diseases, with an emphasis on severe clinical endpoints. Depending on the availability of data, a secondary objective will be to estimate the economic burden of Strep A diseases.
This population-based descriptive study will use routine health data obtained from different low-income and middle-income and high-income countries through international research collaborations to estimate the country-level and global burden of Strep A diseases. Data will be primarily obtained and collated from hospital or national health laboratory databases for individuals across all age groups, along with emergency department, primary care and microbiological datasets where available. Strep A disease endpoints will be identified using International Classification of Diseases 10th Revision or other relevant coding systems and microbiological diagnosis. Age-specific incidence and prevalence rates will be computed using population denominators, and country-level age-adjusted rates will be applied to standard global reference populations to estimate the number of cases globally.
Ethical approval to conduct this study was obtained from the Human Research Ethics Committee at the University of Western Australia (reference: #2024/ET000401) and governance approval was obtained from The Kids Research Institute Australia. The findings from this study will be published in peer-reviewed journals and presented at Strep A Vaccine Global Consortium collaborative meetings.
This study aimed to assess the effect of distance from the nearest health facility on zero-dose children in Ethiopia by using a generalised structural equation modelling.
A cross-sectional secondary analysis of longitudinal data.
Community-based study in five regions of Ethiopia (Tigray, Oromia, Amhara, Southern Nation Nationalities and Peoples (SNNP) regions, and Addis Ababa city).
The final analysis included a weighted sample of 1973 mother–child pairs.
The primary outcome was the direct effect of distance to the nearest health facility on zero-dose children. The secondary outcome was the mediating effect of maternal reproductive health service utilisation on this relationship.
The prevalence of zero-dose children was 15.7%, with significant urban (2.2%) and rural (19.7%) disparities. The median distance to the nearest health facility was 1.93 km, with median distances of 2.10 km for rural and 1.26 km for urban residents. Similarly, the mean distance to the nearest public health facility was 2.09 km (SD = ±1.72). Each additional kilometre from the nearest public health facility was associated with 14.2% higher odds of a child being zero-dose (aOR: 1.14 (95% CI 1.02 to 1.28)). This effect was predominantly direct, accounting for 89.4% of the total effect (aOR: 1.13 (95% CI 1.01 to 1.26)), while the indirect effect mediated through maternal reproductive health service utilisation was minimal and not statistically significant (aOR: 1.01 (95% CI 0.97 to 1.05)).
This study suggests that greater distance to the nearest health facility increases the likelihood of children being zero-dose. Therefore, improving physical access to health services through expanded outreach programmes and mobile vaccination services, and strengthening maternal health services, particularly antenatal care and facility delivery, is essential for reducing the burden of zero-dose children.
To examine how patients and family members decide whether to accept a highly invasive intervention (aortic valve replacement (AVR)) when their condition (aortic stenosis (AS)) is asymptomatic and its course uncertain.
Nested, longitudinal, qualitative substudy of an ongoing randomised controlled trial (RCT) (NCT04204915) testing early intervention (EI) versus watchful waiting (WW) in patients with asymptomatic severe AS.
Six select UK sites of the RCT.
Select participants of the RCT, their next-of-kin and some who declined RCT participation.
73 interviews were conducted, with 41 participants.
Few knew much about AS before diagnosis. Uncertainty and the need for reliable information regarding symptoms and progress was a significant problem.
While some expressed unease at a major intervention for an asymptomatic condition, there were no outright objections to the idea.
Those who declined participation in the RCT did so for personal reasons, for example, their home circumstances did not permit the required period of recovery or they felt too old to risk intervention.
Reasons for accepting early intervention included the belief that the condition was serious and likely to deteriorate, and so better to have the intervention before such deterioration, as well as avoiding long waiting lists. Trusting clinicians’ judgement played a part in some decisions. Patients also wanted choice in the type of intervention received.
The longitudinal interviews (n=32) showed satisfaction in the early intervention group despite some problems in the the early recovery phase, especially for those undergoing surgical AVR.
Where evidence supports major intervention for an asymptomatic condition, patients are likely to accept the offer, although personal circumstances play an important role in decision-making. Where a condition is not well known to the public, such as AS, patients rely on clinicians and other resources to help decide. Liaison with patient groups in developing shared decision-making resources may help with complex decisions.
Earlier heart failure (HF) diagnosis in the community could allow timely treatment initiation and prevent unnecessary hospitalisation, but identifying those at risk remains challenging. We aimed to summarise the performance of risk prediction models for a new diagnosis of HF.
Systematic review of multivariable incident HF risk prediction models in the community setting.
MEDLINE and Embase were searched from inception to 9 November 2023.
Observational, community-based studies reporting prediction model performance for incident HF within a 5-year time horizon.
Two reviewers independently screened and extracted data. Where possible, C-statistics (or area under the receiver operating characteristic curve) with 95% CIs were extracted. Risk of bias was assessed using the Prediction model Risk Of Bias ASsessment Tool and certainty of evidence by the Grading of Recommendations, Assessment, Development and Evaluation.
Eighteen studies described 45 prediction models, 27 used traditional statistical methods and 18 applied machine learning. Most (39/45) demonstrated acceptable discrimination (C-statistic >0.70). Overall, C-statistics ranged from 0.675 to 0.954, typically with narrow 95% CIs. External validation was performed for 31 models, but only two—the modified PCP-HF models for white men and women—were validated in three cohorts, the highest among all the models. Exploratory random-effects meta-analysis of these models showed pooled C-statistics of 0.82 (95% CI 0.82 to 0.82) for men and 0.85 (95% CI 0.82 to 0.88) for women, indicating excellent discrimination but more heterogenous performance among women. Model performance was at high risk of bias due to unreported or inappropriate handling of missing data, and the certainty of evidence was very low.
Risk prediction models for a new diagnosis of HF in the community performed well, but were at high risk of bias and lacked external validation. Future model development requires appropriate data sources, robust handling of missing data, external validation and clinical testing to assess their impact on earlier HF diagnosis and outcomes.
