To examine workplace experiences, perspectives on coming out at work, organisational climate and mental health status of lesbian, gay, bisexual, transgender, queer/questioning and other sexual, and gender minority healthcare providers (LGBTQ+ HCPs) within an East Asian cultural context.
Observational, cross-sectional study.
An online cross-sectional survey was conducted among 173 Taiwanese LGBTQ+ HCPs between May and August 2024.
Most of the 173 respondents did not disclose their LGBTQ+ identities to any colleagues, and approximately two-fifths met the clinically significant threshold for depressive symptoms. Furthermore, compared to LGBTQ+ HCPs who disclosed to all, most, about half or a few colleagues, those who had not disclosed to any colleagues reported higher levels of depressive symptoms, lower self-esteem, less comfort with disclosure, greater perceived necessity to conceal their LGBTQ+ identities, lower scores for job stability or security, poorer interpersonal relations and lower agreement that an LGBTQ+-inclusive workplace climate would influence their willingness to remain in their current jobs. Although approximately 80% of the LGBTQ+ HCPs reported that they were familiar with national workplace antidiscrimination laws and that their organisations had grievance mechanisms, nearly two-fifths did not trust the grievance systems or procedures within their organisations.
Results emphasise the urgent need to create an LGBTQ+-inclusive workplace environment with clear and enforceable antidiscrimination policies and inclusive organisational practices to improve both disclosure safety and mental health outcomes for LGBTQ+ HCPs.
The study results extend existing knowledge by identifying the relationship between different levels of disclosure and mental health status among LGBTQ+ HCPs. They also highlight the importance of establishing support groups, a comprehensive mental health referral system and enforcement mechanisms that safeguard legal rights without compromising the privacy or safety of LGBTQ+ HCPs.

ObjectivesTo monitor sleep patterns of elite swimmers and explore sleep as a potential risk factor for upper respiratory symptoms (URS) alongside salivary Immunoglobulin A (IgA) in elite swimmers, over an 8-month competitive season.
DesignSecondary analysis of an 8-month longitudinal study in elite international swimmers leading into either the Commonwealth Games 2018 or Swim Cup Eindhoven.
MethodsFourteen elite swimmers (age ± SD = 19.9 ± 0.8 years, height = 178.9 ± 6.3 cm, and mass = 75.0 ± 7.7 kg) were recruited. Self-reported sleep quality, URS data and salivary IgA was obtained weekly on a standardised day. Quantitative sleep parameters were measured using wrist-worn actigraphy four times for two-week bouts; during low, moderate, high training loads and once leading into competition.
ResultsSwimmers waking fatigued was positively associated with frequency (p Conclusions
Perceived fatigue on waking was significantly associated with both frequency and severity of URS, and inversely associated with mucosal immunity (salivary IgA), providing novel insight into the relationship between sleep, fatigue and illness in this cohort. Although causality cannot be established, the high prevalence of inadequate sleep shown in elite swimmers highlights the importance of individual sleep monitoring to support recovery and inform strategies aimed at illness prevention.

BackgroundAdolescent pregnancy is associated with several challenges, and partner support is crucial. However, the causal effect of partner support on the use of maternal health services among pregnant adolescents has not been rigorously examined. We assessed the causal effect of partner support on the frequency of antenatal care (ANC) visits among married adolescents in rural Uganda.
MethodsWe conducted a quasi-experimental study using observational data from a cross-sectional study that involved married adolescents aged 10–19 years in rural northwestern Uganda. The primary exposure was partner support, measured as a binary variable. Adolescents were considered to have received support if their spouse encouraged ANC attendance, accompanied them to visits, or provided financial or emotional support during ANC; otherwise, they were classified as having not received support. The primary outcome was the number of ANC visits, while the secondary outcome was attending four or more ANC visits. Propensity score weighting was used to ensure covariate comparability between the partner support groups (yes vs. no). Poisson regression was used to estimate the causal effect of partner support on the number of antenatal care (ANC) visits (primary outcome), while the modified Poisson regression was used to estimate the causal effect on attending four or more visits (secondary outcome).
ResultsOf 281 participants, 205 (72.9%) received partner support. Among participants with partner support compared to those without partner support, the frequency of ANC visits (Risk Ratio 1.15, 95% CI: 1.00–1.32) and four or more ANC visits (Risk Ratio 1.25, 95% CI: 1.01–1.52) improved.
ConclusionThe study showed that partner support was associated with improvements in ANC visit frequency and attendance of four or more ANC visits, among married adolescents in northwestern Uganda. Interventions aimed at improving ANC utilization should consider engaging and educating partners, as their support positively influences ANC utilization.

As populations age, long-term care policies must balance individual preferences with financial constraints. The prevailing “aging in place” policy in France assumes that citizens overwhelmingly prefer home care over nursing homes. However, little is known about people’s preferences towards long-term care options before disability occurs. We elicit preferences among community-dwelling adults over 60 using a mixed-method approach: qualitative interviews and a two-stage D-efficient discrete choice experiment. In each task, respondents chose between two hypothetical nursing homes varying in professional care quality, living environment, out-of-pocket (OOP) cost, and proximity, then decided whether to receive care in this nursing home or remain at home. A sample of 2,886 French adults over 60 completed the survey in 2024. We used random-effect conditional logit and latent class logit models to investigate trade-offs and preference heterogeneity. While a majority (54%) consistently favored home-care, 37% shifted their decision in response to improved nursing home characteristics. Professional care quality and living environment influenced choices as strongly as OOP cost, while proximity plays a secondary role. Strengthening staffing and training, upgrading equipment and the conviviality of shared spaces, and containing OOP costs are direct levers to raise the acceptability of nursing home care.To shed new light on the management practice and needs for support, mentoring and continuous education of nurse managers (head nurses and assistant head nurses) during and since the COVID-19 pandemic to identify the innovative strategies they put in place to mobilise teams and foster a healthy work environment.
A multi-centre exploratory descriptive study with a qualitative descriptive exploratory design was used.
10 focus groups held between December 2021 and July 2022, five from a Canadian healthcare centre and five from a Swiss healthcare centre, were conducted with 35 nurse managers. The data were analysed using thematic analysis.
Six central themes emerged: (1) A difficult context to navigate: Continuous adaptation necessary to navigate through difficulties and a rapidly changing context, (2) Maintaining a visible presence and engaging in active listening with team members to promote commitment, motivation and mobilisation, (3) Frequent short meetings, instant and transparent communication, (4) Role legitimacy and recognition, along with continuous professional development, (5) Integration and cohesion among team members, and the quality of care and (6) Shared leadership: A key strategy to prioritise.
The present study offers unique insights into the innovative strategies nurse managers have put in place to ensure the optimal functioning of their care team, to foster a positive work climate, and to ensure the commitment, motivation and mobilisation of their teams. A shared leadership approach appears to be a key lever of action to optimally tackle the present and future needs and challenges of nurse managers.
This study highlights key managerial strategies that can be beneficial in all contexts or during future crises, ultimately helping healthcare organisations and nurse managers have a better understanding of their role and influence.

Patient falls in hospitals lead to patient harm, staff distress and economic burden on health systems. There are few strategies with robust evidence demonstrating benefit for the prevention of falls, especially in acute hospital settings. Education and multicomponent fall prevention approaches are promising. Rigorous systematic measurement of implementation has been lacking in most hospital fall prevention trials. This paper describes the protocol for a trial that will evaluate the impact of supported implementation of tailored multicomponent fall prevention interventions on patient falls in hospital.
A stepped-wedge hybrid type I effectiveness implementation cluster randomised trial will be conducted. Twelve inpatient wards across four metropolitan hospitals will be enrolled in the trial, clustered into groups of four and randomised to commence the intervention at one of three time periods. Patients and ward staff will be recruited to complete pre-implementation surveys, which, combined with analysis of routinely collected local falls data and staff brainstorming, will inform tailored multicomponent fall prevention interventions for each ward. Wards will receive quality improvement training, clinical facilitation and staff education for at least 4 months to support implementation of their fall prevention interventions. The primary outcome—rate of falls—will be measured using routinely collected hospital falls data from the incident management system and medical records. Pre-implementation and post-implementation patient and staff surveys, qualitative interviews and bedside audits will measure secondary effectiveness and implementation outcomes. Healthcare utilisation from hospital data will inform the cost-effectiveness analysis.

To discuss the dyadic and triadic interviewing techniques as distinct approaches to data collection in qualitative research.
Methodological/methodical discussion.
Underpinned by a layered theoretical basis involving interpretivism, social constructivism and symbolic interactionism, dyadic and triadic interviewing approaches represent a tapestry that seeks to illuminate not only what participants think at the individual level, but also how they think together to generate shared, nuanced meanings. Key methodical considerations include participant recruitment and selection to form the dyads or triads, ethical issues, navigating power dynamics, determining saturation at the dyad or triad level and shifting the unit of analysis from the individual level to the dyad or triad level. Notable challenges to using these approaches include logistical complexity, ethical risks and the great need for skilled moderation.
Dyadic and triadic interviewing techniques occupy a vital methodological niche in qualitative studies, particularly within the contexts of health and social care research where relational dynamics and collaborative decision-making are central. By foregrounding co-constructed narratives and real-time interactions, dyadic and triadic interviewing techniques illuminate the interplay of individual agency, power asymmetries and cultural norms, offering insights that transcend the limitations of individual interviews or focus groups.
The increasing complexity of care, treatment pathways, recovery and family-centered decision making warrants engagement beyond individual interviews. Dyadic and triadic interview techniques facilitate this by combining the in-depth benefit of individual interviews and shared interpretations of focus group discussions to capture meanings and experiences.
This methodological/methodical discussion offers clarity to employing dyadic or triadic interviewing approaches to improve their uptake in health and social care research.

Cognitive impairment is associated with people with diabetes-related foot ulcers (DFU). However, it is unclear if cognitive impairment is associated with the ulcer itself or other co-existing diabetes-related complications such as peripheral neuropathy. We aimed to investigate cognition in people with diabetes-related peripheral neuropathy and compare those with DFUs to those without DFUs. In this age- and sex-matched, multicentre, case-control, observational study of 89 participants with Type 2 diabetes and peripheral neuropathy, we compared 49 participants with DFUs (cases) to 40 without DFUs (controls). Global cognition scores were assessed using the Montreal Cognitive Assessment tool. Participants with DFUs had similar characteristics to those without DFUs (all, p > 0.05), except for lower body mass index (p = 0.028). Participants with active DFUs had significantly lower global cognition scores compared to those without DFUs (median [IQR] 24.0 [21.0–25.0], 26.0 [24.0–28.0]; p < 0.001). After adjusting for other diabetes-related complications, lower global cognition was independently associated with a DFU, peripheral artery disease, lower physical activity and no family history of diabetes (all, p ≤ 0.019). People with DFUs had lower cognitive scores than those without DFUs, suggesting that the DFU itself is independently associated with cognitive impairment. Future studies should explore causal pathways and targeted management strategies.
Hospital falls and associated injuries are a global issue associated with harm and significant costs to individuals and society, especially for older adults. Hospital standards specify the minimum level of care required to optimise patient safety, quality and outcomes. Standards are often used during hospital accreditation. This investigation analysed the content and quality of hospital falls standards across the globe.
Hospital standards were located by searching online databases (PubMed, CINAHL, Google Scholar, MEDLINE), ChatGPT, the grey literature via internet search engines, and websites of accreditation agencies, government agencies, and other relevant organisations. We searched for standards from the 60 largest countries by population plus the 60 countries with the highest gross domestic product (n = 82 after accounting for duplicates). For inclusion, hospital standards had to mention ‘fall/s’. Data were analysed using a deductive framework synthesis and content analysis to identify emergent themes.
Forty-one standards used by at least 72 countries were identified from our search. Sixteen were excluded from detailed analysis because they did not mention falls and 3 could not be retrieved. A total of 22 standards were included in the final detailed analysis. Included standards showed wide variations in content and quality. Seven were assessed as high quality, 12 medium quality, and 3 were deemed to be of low quality. Some lacked details on hospital falls screening, assessment, prevention, and management. Consumer engagement in development, implementation, or evaluation was not mentioned in all standards. Procedures for falls data collection and reporting were seldom documented. Hospital standards infrequently referred readers to contemporary research or clinical practice guidelines.
There are variations in the quality and content of standards on hospital falls. International collaboration is recommended to increase the consistency and validity of hospital falls standards across nations, in order to optimise healthcare outcomes.
The findings of this global analysis of hospital falls standards have the potential to impact falls rates and fall-related injuries in hospital patients by providing data to inform the content, evidence base and use of hospital standards to optimise the safety and quality of care delivery. The findings inform the review, design and implementation of hospital accreditation procedures to improve patient outcomes, patient experiences, and service quality.
To assess anaesthesia capacity and practice in Sierra Leone by enumerating the anaesthesia workforce by volume, training level and distribution across urban and rural areas and facility ownership; estimating the prevalence of anaesthesia methods used for common surgical procedures by provider category; and evaluating hospital infrastructure and the availability of essential anaesthesia-related medications and equipment.
A nationwide, cross-sectional, facility-based study combining structured questionnaires administered through face-to-face interviews with facility leads and retrospective review of surgical and anaesthesia logbooks.
Public and private hospitals and clinics in Sierra Leone providing surgical care with general, regional or local anaesthesia within an operating theatre.
69 of 78 eligible surgical facilities nationwide were included. Facilities providing surgical services between September 2022 and August 2023 were eligible; facilities without registries or declining participation were excluded.
Across participating facilities, the anaesthesia workforce comprised 198 full-time positions, predominantly non-physician providers, with only 40.4% (80/198) trained to administer anaesthesia independently. Ketamine-based and spinal anaesthesia were most common, while general anaesthesia with a protected airway accounted for just 5.0% (415/8339) of procedures. Anaesthesia practices varied by provider training level. Essential infrastructure, equipment and medications fell below international minimum standards, with shortages most pronounced in rural facilities.
Severe shortages of certified anaesthesia providers, limited anaesthesia techniques and inadequate material resources remain major barriers to safe anaesthesia and surgical care in Sierra Leone. Targeted investments in workforce development, infrastructure and resource allocation—particularly in rural areas—are required to improve the safety, quality and equity of anaesthesia care nationwide.

The San Clemente Island fox (Urocyon littoralis clementae) is classified as a focal species for conservation management by the US Navy. They are considered vulnerable to a variety of vector-borne diseases due to their relatively high population density and low genetic diversity. During the dry (July–November) and wet (December–February) seasons of 2017–2018 we live-trapped 95 foxes and collected ectoparasites to test for the presence of pathogens. We found a significant difference in ectoparasite abundance on foxes between seasons, but no differences associated with sex or age. We found that foxes carried two species of flea (Echidnophaga gallinacea and Orchopeas howardi) and two tick species (Ixodes pacificus and Ixodes jellisoni). No evidence of Borrelia burgdorferi, Anaplasma phagocytophilum, or Borrelia miyamotoi bacteria were found. This paper is the first account of ectoparasite species identification, quantification, and pathogen testing for the San Clemente Island fox subspecies.Suboptimal feeding practices in children under five remain a critical concern, particularly in low- and middle-income countries. Integrated Supplementary Feeding programmes (SFPs) combined with Social and Behaviour Change Communication (SBCC) interventions have shown potential, yet global evidence on their design and effectiveness remains scattered across diverse settings and varies widely in scope and quality. This review aims to map global evidence on integrated SFP and SBCC interventions for children aged 6–59 months, assessing their impact on anthropometric, biochemical, nutritional, health, developmental, functional, microbiological and infant and young child feeding (IYCF) outcomes, and to identify contextual factors, evidence gaps and successful strategies. The review will also aim to document cost effectiveness and economic outcomes of this integrated intervention.
The review will follow Joanna Briggs Institute (JBI) methodology, applying the Population–Concept–Context framework and the review title has been registered in Open Science Framework (OSF) (https://doi.org/10.17605/OSF.IO/ZJ5BG). Eligible studies published between 2000 and 2025 will include community-based interventions for children under five that combine SFP and SBCC. The review will focus on SFP interventions delivered through community-based or public health platforms, including but not limited to take home ration, hot cooked meal, micronutrient powders, coupled with SBCC modalities such as home visits, mobile health and mass media campaigns. Comprehensive searches will be conducted in MEDLINE (PubMed), Cochrane CENTRAL, Google Scholar and organisational websites. Two independent reviewers will screen, extract and appraise studies using Covidence and JBI tools. Data will be analysed using descriptive statistics to summarise study characteristics, intervention types and reported outcomes, helping understand patterns across time and settings. Qualitative findings will be synthesised through descriptive content analysis involving coding and theme development. Expected outcomes include a range of study designs from different settings across the globe, covering diverse delivery models of integrated SFP and SBCC with reported outcomes including dietary indicators, anthropometry, nutritional biomarkers, caregiver practices and cost-effectiveness.
This review is part of a larger cluster randomised controlled trial (NECCTAR) which has received ethical approval from the independent institutional ethics committee of all the participating institutes. The current review will involve only publicly available literature and does not have a separate institutional ethics committee approval. Findings will be disseminated through academic conferences and publications in peer-reviewed journals.
The review title has been registered in OSF (https://doi.org/10.17605/OSF.IO/ZJ5BG).
Case reports (CRs) are essential in physiotherapy, yet reporting remains heterogeneous and insufficiently standardised. The 2013 CAse REport (CARE) guideline improves transparency but lacks physiotherapy-specific detail. This study aimed to develop a consensus-driven extension of the CARE reporting guideline to support structured reporting of physiotherapy CRs, encompassing physiotherapy-specific assessments and interventions.
An e-Delphi consensus process study following the ACcurate COnsensus Reporting Document (ACCORD) guidelines.
Online.
Forty-four international experts in physiotherapy practice, research and education, along with six core committee members.
Experts objectively scored items for relevance (5-point Likert scale) and provided open-ended responses for each item of the drafts. Scores and responses were analysed to facilitate iterative refinement of the Physiotherapy CAse REport (PhyCARE) reporting guidelines. Consensus was predetermined at over 70% agreement.
Round 1 had the majority of items achieving ≥70% agreement, except two items that did not meet the threshold were revised and replaced with an alternative. Five new items addressing physiotherapy-specific reporting needs were added, and 10 items were relocated. In round 2, all 35 items across 13 domains achieved 84%–100% agreement. The nomenclature of one domain was revised to ‘Outcomes and Follow-up’. Following two e-Delphi rounds, consensus was achieved, and suggestions from online meeting, piloting led to item rephrasing, after which the PhyCARE guidelines were finalised.
The PhyCARE guidelines have the potential to provide a physiotherapy-specific extension of CARE to support structured, transparent and reproducible reporting of physiotherapy CRs.
To describe obstacles and ideas for improvement for the delivery of cardiopulmonary resuscitation and basic life support to wheelchair users.
A descriptive qualitative study underpinned by constructivism was conducted.
Semi structured interviews were completed with 26 participants from three cohorts: formal and informal carers, wheelchair users and healthcare professionals. Data were collected via online and in person interviews between February and June 2024. All participants were located in Australia, with the exception of one who was located in the United Kingdom. Data were analysed using thematic analysis.
Two major themes were identified: (1) obstacles to providing cardiopulmonary resuscitation and basic life support to a wheelchair user and (2) aspirations for improving cardiopulmonary resuscitation and basic life support for wheelchair users.
Participants shared ideas for how to improve emergency care for wheelchair users, highlighting a need for further research, testing and development of an education intervention.
Improving knowledge about providing emergency care to a wheelchair user could improve outcomes, save lives and reduce the life expectancy gap experienced by people with disability.
Approximately 2% of the global population use a wheelchair. Wheelchair use complicates the delivery of cardiopulmonary resuscitation and basic life support. There are currently no guidelines informing emergency care for wheelchair users available globally. Recognition of common symptoms of distress exhibited by wheelchair users, and options for the delivery of practical emergency care are required for wheelchair users.
The paper adheres to the EQUATOR reporting guidelines utilising the SRQR checklist.
Patients and the public were the driving force in recognising the gap in knowledge regarding the delivery of CPR to wheelchair users. Questions from patients and the public shaped the aims and methodological choices for this study.
To determine the prevalence of burnout and back pain in homecare workers in Switzerland and assess their associations with psychosocial work environment factors.
National multicentre cross-sectional study.
Using paper-pencil questionnaires, data were collected from January 2021 to September 2021 from employees of 88 homecare agencies across Switzerland. Respondents who identified themselves as administrators, apprentices, or trainees, who were in leadership positions, or who were not involved in the provision of care or housekeeping were excluded from this analysis. Burnout was assessed with the Copenhagen Burnout Inventory Scale (possible score range 0–100) and back pain with a single item from the Federal Statistical Office's Swiss Health Survey. Multilevel regression analyses were used to assess burnout and back pain's associations with psychosocial work environment factors.
We included 2514 homecare workers. More than two-thirds (68.6%) reported back pain in the past 4 weeks. The overall mean burnout score was 36.0 (SD 18.3). Poorer work-life balance, higher perceived workload and verbal aggression from clients were positively associated with both outcomes. Better leadership and social support from colleagues were negatively associated with burnout. Higher role conflict levels correlated with higher burnout levels.
Our findings indicate that the psychosocial work environment should be considered when designing interventions to reduce the prevalence of burnout and back pain among homecare workers.
The high reported burnout and back pain prevalences among homecare workers highlight an urgent need to design and implement psychosocial work environment-improving interventions. In addition to contributing to homecare employees' long-term attraction and retention, protecting and promoting their health and well-being will likely not only benefit them, but also contribute to patient safety, quality of care and homecare sustainability.
The study reports the prevalence of burnout and back pain among homecare workers and their associations with psychosocial work environment factors. The results indicate that six psychosocial work environment factors—work-life balance, perceived workload, leadership quality, levels of social support from colleagues, role conflict levels, and verbal aggression from clients—all correlate with burnout and/or back pain in homecare workers. For policy makers, researchers, healthcare managers, and homecare agencies, this study's findings will inform the development of interventions to enhance homecare work environments, leading to improvements both in workers' health and in the quality of their care.
We have adhered to the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting checklist for cross-sectional studies.
Our stakeholder group included patient representatives, policy makers, researchers, clinicians and representatives of professional associations. Throughout the study, all provided support and input on topics including questionnaire development, result interpretation and the design of strategies to improve response rates.
The substantial case detection gap in the field of child tuberculosis (TB) disease is largely driven by inadequate diagnostic tools and approaches. Chest radiographs (CXRs) remain a key component in the evaluation of children and young adolescents (0–15 years) with presumptive TB, aiding clinicians in making the diagnosis and discriminating children with TB from those with other diseases. Widespread use and optimal interpretation of CXR is hampered by a lack of access to well-trained specialists to interpret images. Artificial intelligence CXR interpretation software, termed computer-aided detection (CAD), is now well developed for adults, yet few products have been evaluated in children. The CXR features of child TB are different from those of adults, and as a result, the performance of these CAD algorithms, largely developed for use in adults, will be suboptimal when used in children. Adapting, or fine-tuning adult CAD algorithms, using CXR images from children with presumptive TB, could allow optimisation of these products for use in children. We, therefore, set out to develop a large image and data repository collected from children evaluated for TB (called Catalysing Artificial Intelligence for Paediatric Tuberculosis Research, CAPTURE) with the purpose of evaluating current CAD products and then working with developers and other partners to optimise CAD algorithms for use in children.
We identified approximately 20 studies, from which potentially up to 11 000 CXRs could be used for the proposed project. CXRs and data were eligible for inclusion in the CAPTURE repository if collected from high-quality child TB diagnostic studies that enrolled children with presumptive TB and if CXRs were obtained as part of the baseline assessment. All lead investigators of these studies are members of the CAPTURE consortium. The images and metadata contributed are centrally collated and the key variable of TB case classification as confirmed, unconfirmed or unlikely TB, using an established consensus case definition, is available. All CXRs included in the CAPTURE repository have a consensus radiological interpretation allocated by a panel of independent expert child TB CXR readers who have classified them as ‘unreadable’, ‘normal’, ‘abnormal typical of TB’ or ‘abnormal not typical of TB’. To determine diagnostic performance of existing CAD products, we will evaluate these against a primary composite clinical reference standard (confirmed TB and unconfirmed TB vs unlikely TB), as well as other secondary microbiological and radiological reference standards. A subset of images will be subsequently allocated to a ‘training set’ and made available to developers, academic groups or other parties to either develop novel paediatric CAD products or fine-tune existing adult ones, which will then be re-evaluated by the CAPTURE team using an image subset (‘validation set’) that is independent of the training set.
The CAPTURE study has been approved by Stellenbosch University Health Research Ethics Committee (N22/09/113), with additional ethics approval or waivers by relevant local authorities obtained by consortium members contributing data if required. The final pooled, harmonised and cleaned dataset, as well as the deidentified, renamed CXR images, is stored on a secure cloud-based server. All analyses of existing CAD products, as well as the paediatric-optimised products, will be published in peer-reviewed publications and shared with other stakeholders like the WHO and donor and procurement organisations to guide policy updates and procurement pathways to ensure widespread uptake.

BackgroundHigh-risk (HR) human papillomavirus (HPV) infection remains a great concern in sub-Saharan Africa in men who have sex with men (MSM). The prevalence of anal shedding of HPV and associated risk factors was estimated for the first time in a cross-sectional observational study covering MSM living in N’Djamena, the capital city of Chad.
MethodsMSM were recruited from the community in 21 sites in neighborhoods of 5 districts randomly selected in N’Djamena by respondent-driven sampling (RDS) method. Anal Collector V-Veil UP2™ device was used for anal canal self-sampling. Manual silica-extracted DNA was subjected for HPV detection and genotyping using BMRT Human Papillomavirus Genotyping Real Time PCR assay (Jiangsu Bioperfectus Technologies Co., Ltd., Taizhou, China). HIV serostatus was assessed using two rapid tests in series.
ResultsA total of 70 MSM (mean age: 29.9 years; range, 18–50) were included. The overall acceptability to practice veil-based anal self-sampling was 95.9%. The usability of the veil collector device was high (92.3%), with easy understandable instructions for use and correct placement in the anal canal. Satisfaction questionnaire reported high overall feeling, intimacy respect and lack of shame. The majority of MSM (44/70, 62.8%) showed anal shedding of HPV DNA, with HR-HPV frequently detected (38,70, 54.3%), including HPV-33 (30/70, 42.9%) HPV-68 (16/70, 22.9%), HPV-18 (4/70, 5.7%), HPV-35 (3/70, 4.3%), HPV-58 (2/70, 2.9%), and HPV-45 (1/70, 1.4%). The distribution of genotypes in HR-HPV DNA-positive MSM revealed that HPV-33 (30/70; 42.9%) was the predominant genotype, followed by the HPV-68 (16/70; 22.9%), HPV-18 (4/70; 5.7%), HPV-35 (3/70; 4.3%), HPV-58 (2/70; 2.9%), and HPV-45, HPV-51 and HPV-56 (each type, 1/70;1.4%).Among all HPV detected, only 42 HPV (36.8%) were covered by Gardasil-9® vaccine, including the HR-HPV-33, −18, −58 and −45, and the low risk-HPV-6 (5.7%) and HPV-11 (1.4%). The majority of detected HPV were non-covered by Gardasil-9® vaccine (63.1%). Overall HIV prevalence was 5.7%.
ConclusionsTaken together, these observations point the MSM population in N’Djamena as a very particular core group of HIV and HPV transmission. HIV prevalence was higher than that of general adult population, but limited to only one MSM of twenty. The RDS method of recruitment allowed to include MSM likely belonging to the same sexual network of HPV transmission leading to the selection of an atypical and specific profile of anal HPV distribution. The potential efficacy of HPV prophylactic vaccination in this population can be estimated at relatively weak.
