Environment and weight class linked to skin microbiome structure of juvenile Eastern hellbenders (<i>Cryptobranchus alleganiensis alleganiensis</i>) in human care

by Andrea C. Aplasca, Peter B. Johantgen, Christopher Madden, Kilmer Soares, Randall E. Junge, Vanessa L. Hale, Mark Flint

Amphibian skin is integral to promoting normal physiological processes in the body and promotes both innate and adaptive immunity against pathogens. The amphibian skin microbiota is comprised of a complex assemblage of microbes and is shaped by internal host characteristics and external influences. Skin disease is a significant source of morbidity and mortality in amphibians, and increasing research has shown that the amphibian skin microbiota is an important component in host health. The Eastern hellbender (Cryptobranchus alleganiensis alleganiensis) is a giant salamander declining in many parts of its range, and captive-rearing programs are important to hellbender recovery efforts. Survival rates of juvenile hellbenders in captive-rearing programs are highly variable, and mortality rates are overall poorly understood. Deceased juvenile hellbenders often present with low body condition and skin abnormalities. To investigate potential links between the skin microbiota and body condition, we collected skin swab samples from 116 juvenile hellbenders and water samples from two holding tanks in a captive-rearing program. We used 16s rRNA gene sequencing to characterize the skin and water microbiota and observed significant differences in the skin microbiota by weight class and tank. The skin microbiota of hellbenders that were housed in tanks in close proximity were generally more similar than those housed physically distant. A single taxa, Parcubacteria, was differentially abundant by weight class only and observed in higher abundance in low weight hellbenders. These results suggest a specific association between this taxa and Low weight hellbenders. Additional research is needed to investigate how husbandry factors and potential pathogenic organisms, such as Parcubacteria, impact the skin microbiota of hellbenders and ultimately morbidity and mortality in the species.

Occurrence of advance care planning for persons with dementia, cancer and other chronic-progressive diseases in general practice: longitudinal analysis of data from health records linked with administrative data

Por: Hommel · D. · Azizi · B. · Visser · M. · Bolt · S. R. · Blom · J. W. · Janssen · D. J. A. · van Hout · H. P. J. · Francke · A. L. · Verheij · R. A. · Joling · K. J. · van der Steen · J. T.
Objectives

There are substantial barriers to initiate advance care planning (ACP) for persons with chronic-progressive disease in primary care settings. Some challenges may be disease-specific, such as communicating in case of cognitive impairment. This study assessed and compared the initiation of ACP in primary care with persons with dementia, Parkinson’s disease, cancer, organ failure and stroke.

Design

Longitudinal study linking data from a database of Dutch general practices’ electronic health records with national administrative databases managed by Statistics Netherlands.

Setting and participants

Data from general practice records of 199 034 community-dwelling persons with chronic-progressive disease diagnosed between 2008 and 2016.

Outcome measure

Incidence rate ratio (IRR) of recorded ACP planning conversations per 1000 person-years in persons with a diagnosis of dementia, Parkinson’s disease, organ failure, cancer or stroke, compared with persons without the particular diagnosis. Poisson regression and competing risk analysis were performed, adjusted for age, gender, migration background, living situation, frailty index and income, also for disease subsamples.

Results

In adjusted analyses, the rate of first ACP conversation for persons with organ failure was the lowest (IRR 0.70 (95% CI 0.68 to 0.73)). Persons with cancer had the highest rate (IRR 1.75 (95% CI 1.68 to 1.83)). Within the subsample of persons with organ failure, the subsample of persons with dementia and the subsample of stroke, a comorbid diagnosis of cancer increased the probability of ACP. Further, for those with organ failure or cancer, comorbid dementia decreased the probability of ACP.

Conclusions

Considering the complexity of initiating ACP for persons with organ failure or dementia, general practitioners should prioritise offering it to them and their family caregivers. Policy initiatives should stimulate the implementation of ACP for people with chronic-progressive disease.

Patients sense of gain experience and its influencing factors: a cross-sectional study in Foshan, China

Por: Xia · P. · Liang · B. · Zeng · Q. · Wang · L. · Zhai · L. · Li · M. · Chen · L. · Yang · H. · He · H. · Xu · X. · Gong · W.
Objectives

Patients’ sense of gain experience (PSGE) is the comprehensive feeling throughout the treatment process, which is a critical benchmark for evaluating comprehensive medical and health system reform in China. This study aims to assess the current status of PSGE in public hospitals and identify important associated factors, providing evidence-based recommendations for improving healthcare services.

Design

This was a cross-sectional study conducted from October to November 2023.

Setting

A total of 14 public hospitals in Foshan, Guangdong Province, China.

Participants

There were 3223 responses, including 1592 from outpatients and 1631 from inpatients.

Primary outcome measure

PSGE was assessed across five domains: time accessibility, service accessibility, cost affordability, patient participation and efficacy predictability. Participants were also asked to provide an overall rating of the PSGE.

Results

The overall score for PSGE was 4.47±0.53 (mean±SD), with service accessibility receiving the highest score (4.68±0.50) and affordability the lowest (4.17±0.86). Secondary hospitals scored an overall PSGE of 4.55±0.50, while tertiary hospitals scored 4.42±0.54. Key factors associated with PSGE were overall satisfaction (β=0.164, p

Conclusions

This study found that patients reported a positive PSGE with service accessibility but reported a less positive PSGE with cost affordability. A tier-based disparity was evident, with secondary hospitals outperforming tertiary hospitals in overall PSGE outcome. Stronger PSGE was positively associated with higher scores in overall satisfaction, treatment satisfaction, satisfaction with medical reforms, patient loyalty and hospital reputation. Demographic and institutional factors, such as hospital level, patient type and household registration, were associated with the PSGE. Efforts can be focused on enhancing clinicians’ willingness and competence in discussing treatment costs during clinical encounters. It is essential for policymakers to address disparities in healthcare experiences among patient groups across hospital tiers to advance equitable, patient-centred systems.

Investigating the use and impact of community Care (Education) and Treatment Reviews (C(E)TRs) in people with intellectual disability and autistic people: protocol for a cohort study using electronic health records

Por: McCoy · B. · Bell · L. · Wang · K. · Jin · H. · Hassiotis · A. · Strydom · A. · Downs · J. · Carter · B. · Shetty · H. · Stewart · R. · Ali · A. · Sheehan · R.
Introduction

Care (Education) and Treatment Reviews (C(E)TRs) are intended to reduce unnecessary psychiatric hospital admission and length of stay for people with intellectual disability and autistic people. The use and impact of C(E)TRs have not been systematically evaluated since their introduction in England in 2015. The aims of this study are to describe the demographic and clinical profiles of people who receive a community C(E)TR and to investigate their effects on admission, length of hospital stay and clinical and functional change.

Methods and analysis

We will conduct a retrospective cohort study using de-identified data from electronic health records derived from two large National Health Service mental health providers in London, England, including one replication site. Data will be extracted using the Clinical Record Interactive Search (CRIS) tool for all people with recorded intellectual disability and/or autism who received mental healthcare from 2015. We will identify community C(E)TR events using keyword searches. Community C(E)TRs will be examined in two ways: (1) In a community cohort, we will capture data in the 6-month periods before and after a community C(E)TR and compare this to a matched control group and (2) In a hospital cohort, we will compare groups who did and did not receive a community C(E)TR prior to their admission. We will describe the socio-demographic and clinical profiles of each group and their health service use, and compare C(E)TR and no C(E)TR groups using t-tests (or a non-parametric equivalent). The primary outcomes are admission to a psychiatric hospital (community cohort) and length of psychiatric hospital admission and clinical change (hospital cohort). Admission to psychiatric hospital will be estimated using propensity score weighting and difference-in-differences methods. Cox’s proportional hazard model will be used for length of hospital admission and repeated-measures analysis of variance (ANOVA) will be used to assess clinical change.

Ethics and dissemination

Use of CRIS to examine de-identified clinical data for research purposes has overarching ethical approval. This study has been granted local approval by the South London and Maudsley CRIS Oversight Committee. Findings will be disseminated in an open-access peer-reviewed academic publication, at conference presentations, and to service users and carers in accessible formats.

Patient navigation programmes in cancer care in Africa: protocol for a scoping review

Por: Igibah · C. O. · Asogun · D. O. · Okoduwa · B. · Uzoma · V. I. · Agbabi · O. M. · Osinaike · T. · Shittabey · M.-S. K. · Oigiangbe · M. E. · Lawal · Q. O.
Introduction

Cancer remains a major public health concern worldwide. Patient navigation, developed in the 1990s to address disparities in cancer outcomes, aims to guide patients through the complex healthcare system and improve access to timely, quality care. Despite its proven benefits, little is known about the implementation or impact of patient navigation programmes in African settings.

This scoping review aims to map the current evidence on components, procedures, outcomes and impact, as well as barriers and challenges to implementation of patient navigation programmes in cancer care across Africa.

Methods and analysis

This scoping review will follow Arksey and O’Malley’s scoping review framework, as further developed by Levac et al. A systematic search will be conducted across PubMed, African Journals Online and Google Scholar to identify relevant studies published from database inception to the date of the final search, using a combination of relevant keywords and MeSH terms. Eligible studies must be reported in English, have been carried out in Africa, involved patients diagnosed with cancer or navigating the cancer care continuum, and report on the description, implementation or evaluation of patient navigation programmes. Screening will be managed with Rayyan and carried out through a two-stage process: screening by titles and abstracts, then by full-text screening based on the prespecified inclusion and exclusion criteria. Data will be extracted into a structured Excel spreadsheet and synthesised using qualitative content analysis to identify programme characteristics, outcomes, barriers and implementation challenges.

Ethics and dissemination

This scoping review does not require ethical approval. Our findings will be published in a peer-reviewed, open-access journal on completion.

Shift work sleep disorder and associated factors among healthcare professionals working at Jimma University Medical Center, Southwest Ethiopia, 2022: a cross-sectional study

Por: Dassale · C. · Alemu · B. · Dawud · B.
Objectives

Shift work sleep disorder is a circadian rhythm sleep-wake disorder characterised by insomnia and/or excessive sleepiness associated with a shift work schedule that overlaps with habitual sleep time. This study aimed to assess the prevalence of shift work sleep disorders and associated factors among healthcare professionals working at Jimma University Medical Center, Southwest Ethiopia.

Design

Institutional-based cross-sectional study.

Setting

Tertiary hospital in Southwest Ethiopia.

Participants

The data were collected using a self-administered questionnaire from health professionals recruited using a simple random sampling technique.

Outcome

Shift work-sleep disorder was assessed by the International Classification of Sleep Disorders, the Insomnia Severity Index and/or the Epworth Sleepiness Scale. A logistic regression analysis was conducted to determine the association between the predictor and the outcome variable. The ORs and 95% CIs were determined. Variables with a p value

Result

370 participants were involved in the study, yielding a response rate of 97.6%. The prevalence of shift work sleep disorder was 35.9% (n=133). Working in three shifts (Adjusted OR (AOR) 3.25, 95% CI=1.92 to 5.57), more than 11-night shifts per month (AOR 2.83, 95% CI=1.49 to 5.37), absence of nap (AOR 2, 95% CI=1.14 to 3.52), stress (AOR 4.4, 95% CI=2.36 to 8.2), fatigue (AOR 2.7, 95% CI=1.26 to 3.73), alcohol (AOR 3.9, 95% CI=1.79 to 8.47) and khat (AOR 4.40, 95% CI=1.76 to 10.96) use in the last 3 months was significantly associated with shift work sleep disorder.

Conclusion

One in three healthcare professionals working at Jimma University Medical Center had a sleep disorder related to shift work. Working in three shifts per day, having more than 11-night shifts per month, lack of naps, presence of stress, fatigue and substance use were found to be associated with shift work sleep disorder.

Time to first optimal glycaemic control and associated factors among adult patients with diabetes at the University of Gondar Comprehensive Specialized Hospital, northwest Ethiopia: a retrospective cohort study

Por: Getahun · A. D. · Ayele · E. M. · Tsega · T. D. · Anberbr · S. S. · Geremew · G. W. · Biyazin · A. A. · Taye · B. M. · Mekonnen · G. A.
Objective

To assess the time to first optimal glycaemic control and its predictors among adult patients with type 1 and type 2 diabetes at the University of Gondar Comprehensive Specialized Hospital in Ethiopia.

Design

A retrospective cohort study.

Setting

University of Gondar Comprehensive Specialized Hospital, northwest, Ethiopia.

Participants

We recruited 423 adult diabetic patients who were diagnosed between 1 January 2018 and 30 December 2022 at the University of Gondar Comprehensive Specialized Hospital.

Outcome measures

The primary outcome was the time from diagnosis to the achievement of the first optimal glycaemic control, measured in months. A Cox proportional hazards regression model was fitted to identify predictors of time to first optimal glycaemic control. Data were collected with KoboToolbox from patient medical charts and exported to Stata V.17. The log-rank test was used to determine the survival difference between subgroups of participants.

Results

Median time to first optimal glycaemic control was 10.6 months. Among 423 adult diabetic patients, 301 (71.16%) achieved the first optimal glycaemic control during the study period. Age category (middle age (adjusted HR (AHR)=0.56, 95% CI 0.41 to 0.76), older age (AHR=0.52, 95% CI 0.33 to 0.82)), comorbidity (AHR=0.52, 95% CI 0.35 to 0.76), therapeutic inertia (AHR=0.20, 95% CI 0.13 to 0.30) and medication non-compliance (AHR=0.49, 95% CI 0.27 to 0.89) were significant predictors of time to optimal glycaemic control.

Conclusion

The median time to first optimal glycaemic control was prolonged. Diabetic care should focus on controlling the identified predictors to achieve optimal glycaemic control early after diagnosis.

New regimens of benznidazole for the treatment of chronic Chagas disease in adult participants in indeterminate form or with mild cardiac progression (NuestroBen study): protocol for a phase III randomised, multicentre non-inferiority clinical trial

Por: Marques · T. · Forsyth · C. · Barreira · F. · Lombas · C. · Blum de Oliveira · B. · Laserna · M. · Molina · I. · Bangher · M. d. C. · Javier Fernandez · R. · Lloveras · S. · Fernandez · M. L. · Scapellato · P. · Patterson · P. · Garcia · W. · Ortiz · L. · Schijman · A. · Moreira · O. C.
Introduction

Chagas disease (CD) is one of the most neglected diseases in the world. In Latin America, CD is endemic in 21 countries, with an estimated 70 million people at risk of infection. Current treatments are limited to two nitroheterocyclic compounds: nifurtimox and benznidazole (BZN). Each has significant limitations, including long duration and safety concerns. However, data from recently completed studies suggest that reduced-duration regimens may be equally effective while enhancing safety.

Methods and analysis

NuestroBen is a phase III, randomised, multicentre clinical trial designed to assess whether shorter (2- and 4-week) regimens of BZN are non-inferior to the standard 8-week treatment. A total of 540 adult participants with no evidence of organ damage (the indeterminate form) or with mild cardiac progression (mild electrocardiographic alterations and without systolic dysfunction or symptoms), all in the chronic phase of CD, will be recruited at six study sites in Argentina and two study sites in Bolivia. Participants will be randomised to receive one of the two shortened regimens of BZN (300 mg per day for 2 or 4 weeks) or standard treatment (300 mg per day for 8 weeks). The primary endpoint is sustained elimination of parasitaemia from the end of treatment through 12 months of follow-up. Secondary endpoints will assess sustained clearance of parasitaemia at 1, 4, 6 and 8 months of follow-up from the end of treatment, drug tolerability and adherence to treatment. NuestroBen will also evaluate whether two shortened regimens of BZN improve drug tolerability and treatment adherence compared with the current standard treatment while maintaining efficacy in participants with the indeterminate form of CD or with mild cardiac involvement.

Ethics and dissemination

Adherence to the recommended diabetic retinopathy screening guidelines in pregnant women with pregestational diabetes: a cross-sectional survey study

Por: Widyaputri · F. · Rogers · S. L. · Nankervis · A. J. · Conn · J. J. · Shub · A. · Staffieri · S. E. · Sasongko · M. B. · Fagan · X. J. · Symons · R. C. A. · Lim · L. L.
Objective

Diabetic retinopathy (DR) in pregnancy can cause blindness. National guidelines recommend at least one eye examination in early pregnancy, then ideally 3-monthly, through to the postpartum for pregnant women with pregestational diabetes. Here we examined adherence rates, barriers and enablers to recommended DR screening guidelines.

Design

Cross-sectional survey study, as part of a larger prospective cohort study.

Setting

Participants were recruited from two tertiary maternity hospitals in Melbourne, Australia.

Participants

Of the 173 pregnant women with type 1 (T1D) or type 2 diabetes (T2D) in the main cohort study, with an additional four who participated solely in this survey study, 130 (74.3%) completed the survey.

Primary and secondary outcome measures

This study calculated rates of adherence to guideline-recommended DR screening schedules and collected data on the enablers and barriers to attendance using a modified Compliance with Annual Diabetic Eye Exams Survey. Each of the 5-point Likert-scale survey items was compared between adherent and non-adherent participants using the Wilcoxon rank-sum test and logistic regression models were constructed to quantify associations as ORs.

Results

A retinal assessment was undertaken at least once during pregnancy in 86.3% of participants, but only 40.9% attended during their first trimester and only 21.2% attended the recommended number of examinations. Competing priorities were the main barriers to adherence, with eye examinations ranked as the fourth priority (IQR 4th–5th) among other health appointments during pregnancy. Meanwhile, knowledge of the benefits of eye screening examinations, eye-check reminders and support from relatives was identified as enablers.

Conclusions

Despite the risk of worsening DR during pregnancy, less than half of the participants adhered to recommended screening guidelines, suggesting that eye health is not a priority. Proactive measures to integrate care are needed to prevent visual loss in this growing population.

Mindsets and menses: decoding young womens attitudes towards menstrual leave - an observational study from South India

Por: George · N. · Mahendran · P. · Kulothungan · K. · Dharmaraj · R. B. · Muniyapillai · T. · Subramanian · T. · Muthu Ranga Babu · A. · Arumugam · A. · Subramanian · S. · Shabash Khan · S. · Selvam · S. · Veeraragavan Suresh Babu · A.
Objective

The primary objective of this study is to investigate the perceived need and attitudinal perspectives regarding menstrual leave policies among young women in rural South India. The secondary objective was to determine the socio-demographic, menstrual and workplace-related factors associated with attitudes towards menstrual leave among young women.

Design

An analytical cross-sectional study was performed from May 2023 to August 2023.

Setting

In a rural district of Tamil Nadu, South India.

Participants

The study encompassed 955 young female students above 18 years of age enrolled in educational institutions in a rural district of Tamil Nadu, India. Participants were pursuing diverse professional programmes including medical, dental, allied health sciences, pharmacy and engineering courses.

Outcome measures

The primary outcomes included assessment of basic menstrual characteristics (age of menarche, regularity, product usage and pain experiences), pain evaluation using the WaLIDD scale (which measured working ability, anatomical pain location, pain intensity via Wong Baker scale and pain duration) and attitude assessment through a 10-dimension Likert scale. The attitude assessment explored both supportive factors (pain management, environmental considerations, medical leave allocation, menstruation normalisation and performance impact) and potential concerns (medicalisation, perceptions of fragility, stigma, disclosure issues and abnormal leave usage). Secondary outcome measures encompassed the analysis of factors influencing these attitudes, followed by a multivariable linear regression model to identify significant predictors.

Results

Among 955 female students (mean age 19.56±1.33 years), the majority supported menstrual leave for maintaining hygiene (82.3%) and managing dysmenorrhoea (75.8%). A substantial proportion (64.4%) viewed it as a means of normalising menstruation discourse, while 61.6% believed it could enhance workplace performance. However, concerns existed about medicalising menstruation (47.9%) and reinforcing gender stereotypes (43.4%). Multivariate analysis revealed that medical students (B=0.67, 95% CI: 1.34 to 2.00), those with graduate-educated fathers (B=1.64, 95% CI: 0.31 to 2.97), earlier age at menarche (B=–0.23, 95% CI: –0.45 to –0.01) and participants reporting menstrual interference with daily activities (B=0.96, 95% CI: 0.02 to 0.89) held significantly more positive attitudes.

Conclusion

While young women generally support menstrual leave policies, particularly for hygiene and pain management, there are significant concerns about workplace stigmatisation and gender stereotyping. Educational background, parental education and personal menstrual experiences significantly influence attitudes toward menstrual leave. These findings suggest the need for carefully structured menstrual leave policies that balance biological needs with workplace/student place equality concerns.

Feasibility of respondent-driven sampling to recruit participants with recent abortion experiences in humanitarian contexts: a mixed-methods community-engaged research study

Por: Jayaweera · R. T. · Odhoch · L. · Nabunje · J. · Oduor · C. · Zuniga · C. · Powell · B. · Barasa · W. · Aber · F. · Nyalwal · B. · Kakesa · J. · Wado · Y. D. · Ouedraogo · R. · Fetters · T.
Objective

This study aims to assess the feasibility of respondent-driven sampling (RDS) to recruit participants with recent abortion experiences in humanitarian contexts, and describe the composition of the study sample generated with this sampling method.

Design

This was a three-phase mixed-methods community-engaged research study employing an exploratory and explanatory sequential approach. We conducted in-depth interviews, focus group discussions, an interviewer-administered questionnaire on abortion experiences and a health facility assessment.

Setting

Bidibidi Refugee Settlement, Uganda and Kakuma Refugee Camp, Kenya from November 2021 to December 2022.

Participants

Using RDS, we recruited 600 participants in Kakuma and 601 participants in Bidibidi with recent abortion experiences. In Kakuma, participants were primarily from Burundi, the Democratic Republic of the Congo and South Sudan; participants in Bidibidi were primarily from South Sudan. Most participants in both sites had completed at least some primary school and were not employed.

Outcome measures

RDS recruitment dynamics: convergence and bottlenecks on key sociodemographic variables, recruitment and population homophily, reciprocity of social ties, success and experiences recruiting.

Results

There were minor violations of RDS assumptions, particularly regarding assumptions of reciprocity of ties and seed composition independent of sample. In addition, there was a strong tendency of participants to recruit those from the same home country and living within the same camp zone. However, sample proportions for age, home country, marital status, zone of residence and student status reached equilibrium (stabilised) by around 500 participants at each site, and we were able to quickly attain the study sample size.

Conclusions

While the true representativeness of our sample remains unknown, RDS is a practical and effective recruitment method in humanitarian contexts for sensitive topics, particularly for research questions in which no data or sampling frames exist. However, attention to representativeness and community engagement is essential to optimising its application and ensuring success.

The impact of working conditions on breast cancer outcomes: a study protocol for a population-based cohort study using UK Biobank data

Por: van der Linden · B. W. A. · Carmeli · C. · Duijts · S. F. A. · Guseva Canu · I. · Rohrmann · S. · Chiolero · A.
Introduction

Breast cancer is the most common cancer among women globally. While the impact of lifestyle factors like smoking and obesity on breast cancer risk and survival is well documented, the effect of working conditions is not fully understood. Moreover, breast cancer can reduce employability, making it crucial to identify factors that facilitate return to work and improve life satisfaction. Since breast cancer is affected by sleep and lifestyle, which are related to working conditions, understanding how they affect breast cancer outcomes is key. This study aims to explore the relationship between working conditions and breast cancer outcomes, including incidence, mortality and survival within a causal framework. Our specific aims are to understand the relationship between (1) working conditions and occupational groups and breast cancer outcomes, including the extent to which sleep, lifestyle and breast cancer screening uptake explain these relationships and (2) prediagnosis working conditions, sleep and lifestyle and their effect on return to work and life satisfaction among breast cancer survivors.

Methods and analysis

We will use data from the UK Biobank, a large-scale cohort study with data on 273 825 women between 40 and 69 years old at baseline, followed from 2006 to 2022. The data has been linked with death and cancer registries and includes 8309 incident breast cancer cases. To quantify the effect of working conditions on breast cancer outcomes (aim 1) and their effect on return to work and life satisfaction (aim 2), we will implement g-methods to estimate the average causal effect and employ counterfactual-based mediation analysis to quantify how much mediating factors, such as sleep and lifestyle, explain this effect.

Ethics and dissemination

UK Biobank received ethical approval from the North West Multi-Centre Research Ethics Committee. No further ethical approval was required for the proposed research project. In line with the two aims, four original research manuscripts will be published in open-access peer-reviewed journals to disseminate the findings. In addition, findings will be disseminated at international conferences and scientific meetings.

Introduction

The Quadrivalent human papillomavirus (HPV) Vaccine Evaluation Study with Addition of the Nonavalent Vaccine Study (QUEST-ADVANCE) aims to provide insight into the long-term immunogenicity and effectiveness of one, two and three HPV vaccine doses. Here, we describe the protocol for QUEST-ADVANCE.

Methods and analysis

QUEST-ADVANCE is an observational cohort study including males and females who are unvaccinated or vaccinated with the quadrivalent or nonavalent HPV vaccine in British Columbia, Canada. Female participants who are unvaccinated or vaccinated with 1–3 doses of the quadrivalent or nonavalent HPV vaccine at 9–14 years of age will be recruited approximately 5 or 12 years postvaccination eligibility. Male participants who are unvaccinated or vaccinated with 1 or 2 doses of the nonavalent HPV vaccine at 9–14 years of age will be recruited at approximately 5 years postvaccination eligibility. The study involves a maximum of four visits over a period of 4–5 years for female participants, and two visits over a 12-month period for male participants. At each visit, self-collected swabs (cervico-vaginal or penile) and questionnaire data will be collected. In each study group, a subset of participants will be invited to participate in a substudy evaluating the long-term humoral immunogenicity of the HPV vaccine. Additional blood samples will be collected from participants who are part of the immunogenicity substudy. The total required sample size is 7180 individuals. The primary objectives are (1) to examine vaccine effectiveness in males and females against prevalent genital HPV infections for one, two and three doses of the HPV vaccine compared with unvaccinated participants and (2) to evaluate if there is non-inferior immunogenicity as indicated by type-specific antibody response of one dose of the HPV vaccine in 20–27-year-old females vaccinated at 9–14 years of age compared with historical data of three doses of the HPV vaccine females vaccinated at 16–26 years of age up to 12 years postvaccination.

Ethics and dissemination

QUEST-ADVANCE was approved by the Research Ethics Board of the University of British Columbia/Children’s and Women’s Health Centre of British Columbia (H20-02111). Individual electronic informed consent or assent will be obtained from each participant before any study-specific procedures are undertaken. Results will be published in an international peer-reviewed journal and on the study website.

Until now, there has still been a lack of sufficient evidence on patient-reported outcomes (PROs) measured by the EuroQol-5 Dimension (EQ-5D) in patients with systemic lupus erythematosus (SLE) in China. This study aims to comprehensively assess EQ-5D outcomes and influencing factors in Chinese patients with SLE.

Design

A multicentre, cross-sectional study based on the Chinese Systemic Lupus Erythematosus Treatment and Research Group registry.

Setting

101 hospitals across 27 provinces of China.

Participants

1336 patients with SLE.

Outcome measures

The information on EQ-5D was collected via an online questionnaire. Medical records were obtained from the Chinese Rheumatology Data Centre (CRDC). Clinical influencing factors related to the reported health problems were identified using multivariate logistic regression. Then, each health state was converted into a health utility score based on the Chinese 2014 tariff. Given the ceiling effects, Tobit regression models were used to analyse the factors influencing health utility scores.

Results

A total of 1336 patients with SLE were included. Of them, 626 patients (46.9%) reported health problems using EQ-5D. The proportions of patients reporting problems in mobility, self-care, usual activities, pain/discomfort and anxiety/depression were 12.80%, 5.24%, 14.90%, 27.47% and 30.46%, respectively. The mean utility score was 0.89 (SD: 0.15), and the mean Visual Analogue Scale (VAS) score was 76.80 (SD: 16.54). There was a statistically significant correlation (r=0.503, p

Conclusions

EQ-5D may be a useful, preference-based PRO measure for SLE and could potentially be integrated into routine clinical monitoring of patients with SLE and applied in economic evaluations in the future.

Ambulatory foetal ECG monitoring in low and high-risk pregnancies (AMBER2): a prospective cohort study protocol

Por: Pegorie · C. · Liu · B. · Thilaganathan · B. · Bhide · A.
Introduction

Measuring foetal heart rate (FHR) is critical for assessing foetal well-being, and traditional cardiotocography (CTG), though effective, has limitations such as cost, accessibility and observer bias. Newer non-invasive foetal ECG (NIFECG) devices offer more precise, reliable metrics for FHR variability and could enable remote monitoring, potentially improving early detection of foetal complications like hypoxia and stillbirth.

Methods and analysis

This is a single-centre prospective cohort study taking place in a tertiary maternity unit in the UK. Women with a singleton pregnancy over 26+0 weeks will be approached for participation in the control, foetal growth restriction (FGR) or diabetic groups. The NIFECG home monitoring schedule is 60 min daily for 7 days in the control group, daily from diagnosis until delivery for the FGR group, and daily from 36 weeks until delivery in the Insulin-dependent diabetic group. Longitudinal FHR raw ECG signals will be collected from participants across different gestational age ranges. Reference standards for FHR variability using metrics such as short-term variation, phase-rectified signal averaging acceleration and deceleration capacity will be established. The study will also aim to explore differences in FHR variability in FGR cases against controls and propose safety thresholds to guide decision-making for delivery.

Ethics and dissemination

Approvals have been obtained from the London Stanmore Research Ethics Committee and from the Medicines and Healthcare Regulatory Agency. The results will be published in peer-reviewed journals, presented at conferences and used by the commercial sponsor to pursue European Conformity regulatory compliance marking and future clinical studies.

Objectives

To explore how pre-existing conditions affect the diagnostic process for potential cancer in primary care patients.

Design

Qualitative interview study using thematic analysis underpinned by a critical realist approach.

Setting

Primary care practices recruited through four Clinical Research Networks and UK health charities across England.

Participants

Interviews were conducted with 75 patients with one or more pre-existing conditions (anxiety/depression, diabetes, obesity, chronic obstructive pulmonary disease, Parkinson’s disease or multiple long-term conditions (four or more)) and 28 primary care professionals (general practitioners and nurses).

Results

The study identified legitimacy as a central theme influencing patient trajectories in the health system while trying to receive a diagnosis for symptoms with which they presented to primary care. Patients engaged in self-triage to determine whether symptoms were ‘legitimate’ enough to seek care. Subsequent triaging steps (by receptionists, nurses and online systems) acted as gatekeepers, with decisions influenced by effectiveness of describing the symptom and subjective impressions. During consultations, clinicians relied on a mix of symptom narrative clarity, medical history and objective ‘metrics’ (eg, blood results, family history) to determine legitimacy for further investigations. Pre-existing conditions could either lower the threshold for referrals or obscure potential cancer symptoms. The stigma associated with mental health diagnoses often undermined perceived legitimacy and contributed to delays.

Conclusions

Legitimacy is continuously negotiated throughout the diagnostic pathway. It is shaped by social, moral and biomedical judgements. To promote early cancer diagnosis for patients with pre-existing conditions, clinicians must make legitimacy assessments explicit, reduce stigma especially around mental health and standardise triage processes.

Minimum effective dose of betamethasone for incisional local infiltration for the prevention of postoperative pain after spine surgery: study protocol for a randomised controlled trial

Por: Wang · Y. · Han · B. · Zhao · C. · Ren · H. · Jia · W. · Luo · F.
Introduction

Postoperative pain is particularly pronounced in spinal surgery. Inadequate management of acute postoperative pain not only reduces patient satisfaction and delays recovery but also increases the risk of developing chronic pain. Local infiltration analgesia (LIA) is a widely used technique for perioperative pain management. However, even with the use of long-acting local anaesthetics, such as ropivacaine, postoperative analgesia often remains insufficient. Preliminary evidence suggests that combining diprospan, a mixture of betamethasone disodium phosphate and betamethasone dipropionate, with ropivacaine can significantly reduce analgesic requirements in the immediate postoperative period. However, concerns about steroid-related complications, including hyperglycaemia and surgical site infections, highlight the need to identify the minimum diprospan concentration to achieve a balance between efficacy and safety. This randomised, controlled, evaluator-blinded trial aims to investigate the dose-response relationship of diprospan as an adjunct to ropivacaine for LIA in spinal surgery to determine the minimum effective dose for effective and safe pain management.

Methods and analysis

This is a single-centre, randomised, evaluator-blinded, controlled, dose-mapping study in which subjects will be randomised in a 1:1:1:1:1 ratio to the control group or to receive diprospan at concentrations of 0.003%, 0.006%, 0.009% or 0.012%. Patients will receive either 0.5% ropivacaine alone or a corresponding dose of diprospan combined with 0.5% ropivacaine for LIA. All participants will be followed for a duration of 3 months. The primary outcome measure will be cumulative sufentanil consumption within the first 48 hours postsurgery. Secondary outcomes will include additional assessments of analgesia, steroid-related adverse events and other complications within the 3-month follow-up period.

Ethics and dissemination

This study protocol was approved by the Institutional Review Board of Beijing Tiantan Hospital (KY2024-365-02-1). Written informed consent will be obtained from all participants. The results will be submitted for publication in a peer-reviewed journal.

Use of ambulatory pathways in emergency general surgery: a systematic review

Por: Fox · B. · Walters · M. · Pathak · S. · Peckham-Cooper · A. · Blencowe · N. S.
Objectives

Ambulatory care is defined as the provision of medical treatment by healthcare professionals outside an inpatient hospital setting. While well-established in acute medicine, uptake of ambulatory pathways in emergency general surgery (EGS) is variable and optimal design and delivery is unclear in this context. This systematic review sought to (1) appraise current EGS ambulatory pathway literature and (2) ascertain the constituent components across the identified pathways, guiding the development of comprehensive templates for future EGS ambulatory pathways.

Design

Systematic review.

Data sources

PubMed, Embase, Medline and Cochrane Library, from 5 December 2018 to 5 December 2023 inclusive.

Eligibility criteria

All primary observational studies (ie, case–control, cohort studies and randomised controlled trials (RCTs)) were included. Case series and conference abstracts were excluded due to the high likelihood of incomplete data. Studies reporting paediatric or non-surgical populations, or ambulatory surgical care within a primary care setting, were also excluded.

Data extraction and synthesis

General study characteristics (year and journal of publication, country of origin, study design, disease area, number of patients receiving ambulatory management and use of control groups) were recorded. To identify the constituent components of EGS ambulatory pathways, an initial subset of five papers was reviewed, from which four categories were identified (decision-making processes, scoring/classification systems, investigations and care escalation and discharge criteria). An additional fifth component (‘follow-up’) was identified during data extraction. Reporting of the constituent components of ambulatory pathways was also extracted, as well as outcomes including readmission, complications and mortality.

Results

Of 43 included studies, there were 8 RCTs, 31 cohort studies and 4 studies using other methods. Reporting of all aspects of EGS ambulatory pathways was heterogeneous. 24 (56%) papers reported the specialty and grade of clinician acting as senior decision-maker. 17 different scoring/classification systems were used. 32 (74%) papers described using investigations to select ambulatory patients, including blood tests (n=12) and imaging (n=16). Eight studies (19%) specified both care escalation and discharge criteria. Information about follow-up was described in 29 papers, with location (n=29), time points (n=26), personnel (n=16) and the form of the follow-up (n=23) all reported variably. Readmission rates were recorded in 34 studies and ranged from 0% to 13%. Most studies (n=32) reported 30-day readmission, although 48 hours (n=1) and 90 days (n=1) were also used. Mortality was recorded in 24 papers, with 21 reporting a mortality rate of 0 and the remaining 3 reporting rates of

Conclusions

Key components of published EGS ambulatory pathways include decision-making processes, scoring/classification systems, investigations, care escalation and discharge criteria, and follow-up. However, this information is currently inconsistently reported. Future work to identify and agree on guidelines for the ‘core’ components of ambulatory EGS pathways is needed, to facilitate cross-study comparisons, and crucially, provide a ‘gold-standard’ framework for developing future ambulatory pathways.

Introduction

Although lung cancer remains the leading cause of cancer deaths in the US, recent advances in early detection and treatment have led to improvements in survival. However, there is a considerable risk of recurrence or second primary lung cancer (SPLC) following curative-intent treatment in patients with early-stage non-small cell lung cancer (NSCLC). Professional societies recommend routine surveillance with CT to optimise the detection of potential recurrence and SPLC at a localised stage. However, no definitive evidence demonstrates the effect of imaging surveillance on survival in patients with NSCLC. To close these research gaps, the Advancing Precision Lung Cancer Surveillance and Outcomes in Diverse Populations (PLuS2) study will leverage real-world electronic health records (EHRs) data to evaluate surveillance outcomes among patients with and without guideline-adherent surveillance. The overarching goal of the PLuS2 study is to assess the long-term effectiveness of surveillance strategies in real-world settings.

Methods and analysis

PLuS2 is an observational study designed to assemble a cohort of patients with incident pathologically confirmed stage I/II/IIIA NSCLC who have completed curative-intent therapy. Patients undergoing imaging surveillance will be followed from 2012 to 2026 by linking EHRs with tumour registry data in the OneFlorida+ Clinical Research Consortium. Data will be consolidated into a unified repository to achieve three primary aims: (1) Examine the utilisation and determinants of CT imaging surveillance by race/ethnicity and socioeconomic status, (2) Compare clinical endpoints, including recurrence, SPLCs and survival of patients who undergo semiannual versus annual CT imaging and (3) Use the observational data in conjunction with validated microsimulation models to simulate imaging surveillance outcomes within the US population. To our knowledge, this study represents the first attempt to integrate real-world data and microsimulation models to assess the long-term impact and effectiveness of imaging surveillance strategies.

Ethics and dissemination

This study involves human participants and was approved by the University of Florida Institutional Review Board (IRB), University of Florida IRB 01, under approval number IRB202300782. The results will be disseminated through publications and presentations at national and international conferences. Safety considerations encompass ensuring the confidentiality of patient information. All disseminated data will be de-identified and summarised.

Cohort profile: trajectory of knee health in runners with and without heightened osteoarthritis risk (TRAIL) in Australia--prospective cohort study

Por: De Oliveira Silva · D. · Mentiplay · B. F. · Girdwood · M. · Haberfield · M. J. · Bruder · A. M. · Culvenor · A. G. · West · T. J. · Hill · J. P. · Carey · D. L. · Johnston · R. T. R. · Crossley · K. M.
Purpose

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

Participants

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

Findings to date

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

Future plans

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