Introduction

Rates of mental health difficulties among girls and young women in the UK have risen sharply, and disproportionately so for those from marginalised groups. My Story and Me is a new digital public mental health intervention that uses storytelling to reduce stigma, increase awareness and support early help-seeking among girls and young women aged 14–18. The feasibility study aims to determine the acceptability of the intervention and future full trial, including assessing optimal settings and meaningful changes in the primary outcome measure (anxiety and depression).

Methods and analysis

This is an 18-month mixed-methods, uncontrolled feasibility study conducted in secondary schools, further education colleges and community organisations across the UK. We will recruit 120–180 participants. Quantitative data will be collected at baseline and 7-month follow-up. The primary outcomes are anxiety and depression, and secondary outcomes are social support, mentalising, stigma, quality of life, loneliness, empowerment, intervention acceptability, resource use and randomisation acceptability. Platform-level engagement data will assess adherence and fidelity. Qualitative interviews with young women and staff will explore acceptability, feasibility, mechanisms of change and views on trial procedures, including randomisation in a future full trial. Analysis will be descriptive and exploratory, including comparisons across settings and priority groups (LGBTQIA+, neurodivergent and those experiencing digital poverty). A framework and reflexive thematic analysis approach will be used for qualitative data. Prespecified progression criteria will inform decisions about advancing to a full cluster randomised trial.

Ethics and dissemination

The University College London Research Ethics Committee (0692) has approved the My Story and Me protocol. Interested participants will be required to complete an expression of interest and consent form to take part in the study, and young people under 16 years old will be required to obtain parent/carer informed consent. Results will be disseminated through peer-reviewed publications, lived experience summaries, a policy briefing and academic conference presentations.

Sucralose inhibited cell survival through the activation of ER stress in human endothelial progenitor cells

by Chia-Ying Li, Hung-Yu Lin, En-Pei Isabel Chiang, Hung-Chang Hung, Feng-Yao Tang

Sucralose, a widely utilized non-caloric sweetener, is frequently added to food and beverage products as a sugar substitute aimed at lowering energy consumption and reducing obesity-related health risks. However, epidemiological studies have indicated a possible association between high intake of sucralose and increased prevalence of coronary artery disease (CAD). Prior research has demonstrated that diminished levels of circulating human endothelial progenitor cells (hEPCs) are linked to a higher risk of CAD. Although sucralose is broadly consumed, its direct biological impact on hEPCs has not been comprehensively characterized. In this study, we investigated the cellular effects of sucralose on hEPCs using a variety of in vitro techniques, including assays for viability, migration, capillary-like tube formation, lactate dehydrogenase (LDH) release-cytotoxicity assay, and protein expression profiling by Western blotting. Our results revealed that increased concentrations of sucralose significantly impaired hEPCs viability, motility, and neovasculogenic function, accompanied by increased expression of markers associated with apoptosis, inflammasome activation, and pyroptosis. Mechanistic analysis further demonstrated that sucralose strongly activated endoplasmic reticulum (ER) stress/PERK pathways in these cells. Inhibition of ER stress via 4-phenylbutyric acid (4-PBA) substantially attenuated sucralose-induced cell death and reduced the expression of pyroptosis-related proteins and inflammasome markers. Taken together, these findings suggest that sucralose disrupts hEPCs function in part by triggering ER stress, which promotes both apoptotic and pyroptotic cell death programs.

The effects of increasing dosages of narasin on ruminal fermentation patterns, bacterial community composition, and nutrient digestibility in beef cattle receiving feedlot diets

by Ana Laura Januário Lelis, Leandro Aparecido Ferreira da Silva, Daniel Moretto Casali, Tiago Leiva, Murilo Chuba Rodrigues, José Paulo Roman Barroso, Pedro Veloso Facury Lasmar, Camila Lisboa Tomaz, Anabelle Jorge Barbosa, Camila Cesario Fernandes Sartini, Johnny Maciel de Souza, Danilo Domingues Millen

This study evaluated the effects of increasing narasin doses on ruminal fermentation, nutrient digestibility, ruminal pH stability, papillae histology, and microbial composition in Angus cattle fed feedlot diets. Three rumen-cannulated Angus steers (average body weight: 680 kg) were assigned to a 3 × 3 Latin square design and received diets containing 13, 20, or 27-ppm of narasin. Each experimental period consisted of 14 days of adaptation followed by seven days of sampling. Ruminal degradability was assessed on days 15–17, apparent digestibility on days 15–19, continuous ruminal pH on days 19–20, and samples for short-chain fatty acids (SCFA), microbiota, and ruminal histology were collected on days 20 and 21. Ruminal degradability was not affected by narasin dose. Digestibility of acid detergent fiber (ADF) was significantly influenced, with the greatest values observed at 27-ppm (P = 0.01). Increasing narasin doses improved ruminal pH stability, as indicated by a linear increase in minimum pH (P = 0.01) and a reduction in the duration of pH below 5.6 (P = 0.10). At 13 ppm, SCFA production, particularly acetate and propionate, increased (P P P = 0.02), and butyrate (P P P = 0.03). Narasin supplementation altered ruminal microbial composition, increasing the relative abundance of Lachnospiraceae and Isotricha while reducing lactic acid–producing bacteria. In terms of ruminal morphology, supplementation with 20-ppm of narasin increased the keratin layer thickness of ruminal papillae (P = 0.02), suggesting enhanced epithelial development. Overall, narasin supplementation modulated ruminal function and microbial ecology, with doses between 13 and 20-ppm providing the most favorable balance between fermentative efficiency and ruminal health in feedlot cattle.

Integrating sequence-based GWAS and comparative genomic analysis reveals conservation and species-specificity of putative functional variants influencing tail length and tail abnormalities in pigs and sheep

by Xuying Zhang, Johanna Mainzer, Isabella Giambra, Tong Yin, Petra Engel, Hannah Hümmelchen, Henrik Wagner, Axel Wehrend, Christiane Egerer, Katharina Gerhards, Gerald Reiner, Sven König

Long tails trigger tail biting in pigs and increase the risk of flystrike infections in sheep. Tail docking has been a common management practice in both species for decades, but increasingly conflicts with legal animal welfare guidelines. Sustainable solutions require breeding strategies targeting shorter tails. In consequence, the aims were to conduct whole-genome sequencing (WGS)-based genome-wide association studies (GWAS) and comparative genomic analyses (CGA) to explore functional elements influencing tail traits. Phenotypically divergent experimental populations of pigs and sheep were established through unified selection and mating experiments. Tail traits included tail length (TL) measured at birth, and tail abnormalities (TA) assessed radiographically at 14 weeks of age. WGS-based GWAS identified a significant locus on SSC18 in pigs and suggestive loci for TL in both species, which, together with previously reported loci for TA, were further analyzed by CGA. The genomic windows of the significant locus on SSC18 in pigs and the TL GWAS locus on OAR4 in sheep were found to be conserved, harboring six common genes with predicted functional variants. These variants were jointly associated with TL (Plm) in both species in linear regression models adjusted for sex, age of the dam, body length, and body weight. In other GWAS locus windows (±1 Mb), species-specific TL candidate genes were identified in sheep (HOXB13, MUC5B, EPB41L3, MTCL1, PIEZO2, MPPE1, and LOXHD1) and in pigs (KNL1, DISP2, SPRED1, TGFB2, and HAND1), each harboring associated putative functional variants. For TA, sheep-specific candidates (PGM2, LRRC66, CRACD, LOC105601916, and SH2D4B) and pig-specific candidates (MYOT, TMCO6, and PCDHAC2) were revealed using logistic regression models (Pglm). GO analyses of candidate genes predicted shared biological processes between sheep and pigs, whereas pathway analyses indicated that common carbohydrate metabolism pathways, along with species-specific immune and inflammatory signaling, and pig-specific TGF-β signaling and endochondral ossification, may contribute to tail length variation and abnormalities. These findings provided deeper insights into the genetic basis of differential embryonic tail morphogenesis and perinatal tail development across species.

Utility of Xpert MTB/RIF using bronchoalveolar lavage samples for the diagnosis of pulmonary tuberculosis in negative or sputum-scarce adults: a systematic review and meta-analysis protocol

Introduction

Tuberculosis is the leading cause of death globally from a single infectious agent. Early diagnosis is critical to reducing morbimortality. In cases of negative smear microscopy or limited sputum production, bronchoalveolar lavage (BAL) samples offer an alternative for diagnosis. Culture, the gold standard, requires a high bacterial load, extensive infrastructure and is time-consuming. Xpert MTB/RIF provides faster results with a higher cost. Previous systematic reviews present substantial limitations, including significant heterogeneity. Therefore, the diagnostic utility of Xpert MTB/RIF using BAL samples in adults with negative or scant sputum for pulmonary tuberculosis (PTB) needs to be reassessed.

Methods and analysis

A systematic search of MEDLINE, Embase, LILACS and Web of Science will be conducted without language or publication date restriction. Cross-sectional diagnostic studies of negative or sputum-scarce adults with presumptive PTB who underwent bronchoscopy to obtain samples for Xpert MTB/RIF and culture will be included. Screening and data extraction will be performed independently. Methodological quality will be assessed using the QUADAS-2 tool. A bivariate hierarchical random-effects model will synthesise sensitivity and specificity. Meta-analysis will be performed using Meta-DiSc 2.0. Heterogeneity will be assessed using I2 and Cochrane thresholds. Subgroup analyses will be performed based on study design, population differences, country, culture method and risk of bias. Publication bias will be investigated using a funnel plot. The certainty of evidence will be evaluated using the Grading of Recommendations Assessment, Development and Evaluation approach. There was no patient or public involvement in the development of the systematic review protocol.

Ethics and dissemination

Ethical approval is not required as this study will use publicly available data. Findings will be disseminated through peer-reviewed publication.

STRATUM-OS: first step in the development and validation of the STRATUM tool based on multimodal data processing to assist surgery in patients affected by intra-axial brain tumours - observational study protocol

Por: Fabelo · H. · Ramallo-Farina · Y. · Morera · J. · Pineiro · J. F. · Lagares · A. · Jimenez-Roldan · L. · Burström · G. · Garcia-Bello · M. A. · Garcia-Perez · L. · Falero · R. · Gonzalez · M. · Duque · S. · Rodriguez-Jimenez · C. · Hernandez · M. · Delgado-Sanchez · J. J. · Paredes
Introduction

Integrated digital diagnostics can support complex surgeries in many anatomic sites, and brain tumour surgery represents one of the most complex cases. Neurosurgeons face several challenges during brain tumour surgeries, such as differentiating critical tissue from brain tumour margins. To overcome these challenges, the STRATUM project will develop a 3D decision support tool for brain surgery guidance and diagnostics based on multimodal data processing, including hyperspectral imaging, integrated as a point-of-care computing tool in neurosurgical workflows. This paper reports the protocol for the development and technical validation of the STRATUM tool.

Methods and analysis

This international multicentre, prospective, open, observational cohort study, STRATUM-OS (study: 28 months, pre-recruitment: 2 months, recruitment: 20 months, follow-up: 6 months), with no control group, will collect data from 320 patients undergoing standard neurosurgical procedures to: (1) develop and technically validate the STRATUM tool and (2) collect the outcome measures for comparing the standard procedure versus the standard procedure plus the use of the STRATUM tool during surgery in a subsequent historically controlled non-randomised clinical trial.

Ethics and dissemination

The protocol was approved by the participant ethics committees. Results will be disseminated in scientific conferences and peer-reviewed journals.

Factors associated with unmet healthcare needs in patients using Primary Care Access Points for unattached patients in Quebec (Canada)

by Mylaine Breton, Catherine Lamoureux-Lamarche, Véronique Deslauriers, Djamal Berbiche, Maude Laberge, Annie Talbot, Aude Motulsky, Marie-Pascale Pomey, Isabelle Gaboury

Background

Access to primary care is an important component of health systems. Given the barriers experienced by unattached patients to accessing primary care in Quebec (Canada), the Ministry of Health mandated the province-wide implementation of Primary care access points for unattached patients (Guichet d’accès première ligne; GAP), an organizational innovation designed to orient patients to the most appropriate professional or service. This study aims to 1) document the factors associated with unmet healthcare needs after receiving GAP services and 2) assess whether those factors vary by GAP orientation.

Methods

This cross-sectional study builds on data collected between April and July 2024 using an online patient questionnaire. All patients with a valid email address registered on the centralized waiting list for unattached patients in three local health territories (LHTs) received an email invitation to participate in the survey. The total sample included 20,282 participants who responded to the questionnaire and used the GAP.

Results

The findings showed that younger age, self-reporting poor/fair physical and mental health, receiving services in LHT 3 and reporting an emergency room visit were associated with increased likelihood of reporting unmet needs. Stratified analyses suggested that some characteristics (age, use of emergency room) were associated with unmet needs across orientations, while others (self-reported physical and mental health) were associated with specific orientations.

Conclusion

This study serves as a first step in deepening our understanding from a patient perspective of how to better plan primary care services and improve unattached patients’ experiences using the GAP. The findings showed that patients oriented to other professionals than a medical appointment with a family physician had the highest percentage of unmet needs. The next step involves an in-depth exploration of the reasons for patients’ unmet needs, enabling the development of more precise and effective strategies to address them.

Extended-spectrum β-lactamase and carbapenemase-producing <i>Enterobacterales</i> among adult patients and their family members at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia

by Dessie Abera, Adane Mihret, Surafel Fentaw, Eyob Beyene, Abel Abera Negash, Woldaregay Erku Abegaz

Background

Extended-spectrum β-Lactamase and Carbapenemase-producing Enterobacterales cause severe infections and currently, they are spreading beyond hospitals and becoming a serious global health concern. They often colonize the gut silently, facilitating the transmission of resistant bacteria between patients and family members.

Objective

We sought investigate the prevalence and molecular characteristics of Extended-spectrum β-Lactamases-producing Enterobacterales (ESBL-PE), Carbapenem-resistant Enterobacterales (CRE), and factors associated there in among admitted adult patients and their family members at Tikur Anbessa Specialized Hospital, Addis Ababa, Ethiopia.

Methods

A case-control study was conducted among 100 patients and their respective 100 family members from February 2023 to October 2023. Stool specimens were collected and processed using standard microbiological techniques. Antimicrobial susceptibility testing and ESBL production were determined using VITEK 2 system. Carbapenemase production was tested using modified carbapenem Inactivation method, and detection of resistance genes was performed by PCR.

Result

Intestinal colonization with ESBL-PE was higher in patients (39.0%) than their respective family members (24.0%) (P = 0.028). Among patients, ESBL production was common in E. coli, 40.3% and K. pneumoniae, 34.7% than their family members 24.2% and 22.2%, respectively. Of the ESBL-PE isolates, 84.6% from patients and 100% from family members carried at least one ESBL encoding gene, with blaCTX-M being the predominant. Colonization with CRE and Carbapenemase-Producing Carbapenem-Resistant Enterobacterales was found to be 19.0% and 10.0%, respectively. These were identified only among patients, with blaNDM and blaOXA-48 are the most prevalent genes. Older age (>53 years) (P = 0.02) and previous ICU admission (P  Conclusion

ESBL-PE colonization was more prevalent in patients compared to their family members, with blaCTX-M identified as the most common gene. Exclusive detection of carbapenemase genes among patients, and the association of previous ICU admission with ESBL-PE colonization, highlights the need for targeted screening and strengthened infection prevention.

Trajectories of cigarette smoking and exposure to welding fumes and their impact on lung cancer risks: a latent class modelling approach

Por: Kendzia · B. · Taeger · D. · Pohabeln · H. · Ahrens · W. · Wichmann · H.-E. · Jöckel · K.-H. · Brüning · T. · Behrens · T.
Objectives

Traditional epidemiological approaches usually assume a constant relationship between cumulative exposure and disease, which implies that exposure duration and intensity contribute equally to the studied outcome. But individuals with the same cumulative exposure but different temporal exposure patterns may show different risks. Trajectory classification is a good way to assess exposure–risk associations and leads to a better understanding of lifetime variability in exposure levels. Therefore, this study aimed to estimate lung cancer risk according to the exposure trajectory classes on welding fumes and cigarette smoking.

Design

Two population-based German case–control studies.

Participants

3498 male lung cancer cases and 3539 male control subjects.

Methods

Separate latent class mixed models (LCMM) were determined to identify profiles of exposure trajectories of cigarette smoking and occupational exposure to welding fumes. To investigate the risk of lung cancer by class membership, ORs with 95% CI were estimated via multiple logistic regression analyses.

Results

LCMM each identified four latent classes of smoking and welding-fume exposure. Classes of smokers showed much higher risk of lung cancer compared with never smokers or subjects exposed to welding fumes. Smokers in one class characterised with the highest exposure over the past 10 years had the highest adjusted lung cancer risk (OR=39; 95% CI 29 to 53). For welding, the highest lung cancer risks were found for the class in which exposure to welding fumes in the past 10 years prior to the diagnosis of lung cancer was highest and the duration of welding was also quite high (OR=1.71; 95% CI 0.92 to 3.15).

Conclusions

In summary, LCMM opens a new perspective on dose–effect relationships and could be employed to complement established epidemiological methods.

Custom foot orthoses for chronic metatarsalgia: Study protocol for a participant- and assessor-blinded superiority randomized controlled trial

by Eléna Payen Schalkens, Maxime Acien, Andrée-Anne Marchand, Pier-Luc Isabelle, Jacques Abboud, Gabriel Moisan

Background

Chronic metatarsalgia (CM) causes significant pain and disability, affecting quality of life. Foot orthoses (FOs) including medially wedged designs with a metatarsal pad decrease excessive plantar pressure under the metatarsal heads, which is a suggested risk factor for developing CM. This FOs model may be effective in diminishing pain and improving function in these individuals. Thus, the objective of this trial will be to compare the effects of medially wedged FOs with a metatarsal pad and sham FOs on pain and foot function in individuals with CM.

Methods/design

This participant- and assessor-blinded superiority randomized controlled trial (RCT) with two parallel groups will be conducted in Trois-Rivières, Canada. Sixty-four participants with CM will be recruited from the Université du Québec à Trois-Rivières outpatient podiatry clinic and via social media invitations. They will be randomized into intervention (customized FOs) or control (sham FOs) groups and will be evaluated at baseline and after 6 and 12 weeks. The primary outcome will be: (1) mean pain during walking for the most painful foot during the past week. The secondary outcomes will be: (1) Foot Function Index, (2) Global rating of change and (3) the 5-level EQ-5D.

Discussion

Medially wedged FOs with a metatarsal pad are expected to provide a greater reduction in pain and improvement in foot function compared to sham FOs. This trial will help guide FOs prescription recommendations for managing foot pain in individuals with CM in the future.

Placebo and nocebo in clinical practice: An online cross-sectional survey of healthcare professionals from European countries on views, practices and training needs

by Mary O’Keeffe, Nathan Skidmore, Arianna Bagnis, Przemysław Bąbel, Elżbieta A. Bajcar, Alessandra De Palma, Andrea W.M. Evers, Eveliina Glogan, Julia W. Haas, Stefanie H. Meeuwis, Marek Oleszczyk, Antonio Portolés, Johan W.S. Vlaeyen, Katia Mattarozzi, on behalf of PANACEA Consortium

Background

Placebo and nocebo effects significantly influence health outcomes, yet healthcare professionals receive limited training and guidance on their mechanisms and clinical application, creating a gap in education and practical understanding. Conducted within the European PANACEA Consortium, this study evaluated healthcare professionals’ knowledge, attitudes, and practices regarding placebo and nocebo effects, and assessed their needs in further education.

Methods

An online cross-sectional survey among a European multi-country convenience sample of healthcare professionals collected data assessing participants’ knowledge, perceptions, and experiences regarding placebo and nocebo effects; their application and ethical considerations in clinical practice; and investigated educational needs and interest in further training. Quantitative data were analyzed using descriptive statistics, and thematic analysis was applied to the free-text responses.

Results

Amongst 807 participants, 71.7% reported taking advantage of placebo effects in their practice, and over half of participants (55.8%) observing nocebo effects. Participants reported feeling somewhat confident (53.3%) in harnessing placebo effects with 47.5% feeling confident in preventing nocebo effects. The majority of respondents had not received formal training on placebo and nocebo effects, with most expressing an interest in further training in areas such as healthcare education, emphasizing communication skills to enhance placebo effects, and knowledge to recognize and reduce nocebo effects.

Conclusions

There is a significant need for more comprehensive training on placebo and nocebo effects, particularly in early health professional education. These findings informed the development of educational resources and best practice recommendations developed as part of the outcomes from the PANACEA Consortium, improving the understanding and application of these effects among healthcare professionals across Europe.

Nurses' Perceptions of Fundamental Care in Preventing Venous Ulcer Recurrence: A Qualitative Focus Group Study

ABSTRACT

Venous ulcers are the most prevalent among those affecting the lower limbs, with high economic and quality of life impact. Due to the chronicity of venous disease, healing and recurrence cycles are common. Patient adherence to self-care activities to prevent recurrence is very low, so it is crucial to reflect on nurses' experiences with this phenomenon. A qualitative and descriptive study was developed to analyse nurses' perceptions about preventing venous ulcer recurrence. According to the inclusion criteria, focus groups with nurses were implemented. Three focus groups were conducted through the Colibri platform, ensuring all ethical assumptions. Content analysis was performed according to thematic criteria, using the WebQda software. Three main themes emerged: integration of care, context of care, and relationship. The participants emphasised the importance of holistic assessment and the establishment of common goals to promote adherence to fundamental recurrence prevention care. Understanding and respecting individual values, empathy and active listening, considering the established relationship, anticipating the person's needs, and trust are essential to overcoming barriers to implementing recurrence prevention care and to its continuity. Taking these aspects into consideration implies that the professional is part of the process of preventing the recurrence of venous ulcers.

Predictive effects of diabetes-related risk factors for falls in community-dwelling people with diabetic peripheral neuropathy based on a logistic regression model

by Eneida Yuri Suda, Cristina Dallemole Sartor, Anice de Campos Passaro, Ricky Watari, Eunice Young Docko, Isabel C. N. Sacco

Background

This study aimed to identify the predictive effects of different aspects of diabetic peripheral neuropathy (DPN) and other already known risk factors for falls through a comprehensive logistic model within community-dwelling older adults with diabetes and DPN. This paper also provides a model that estimates the probability of a fall occurring in a real-world clinical scenario.

Methods

This cross-sectional retrospective study analyzed data from subjects that had never fallen (non-fallers, n = 534) and that had fallen at least twice in the previous year (fallers, n = 101). The logistic regression analysis was performed on a training sample randomly extracted from the original sample (non-fallers: n = 85; fallers: n = 81). The model was validated by checking the performance parameters using a test sample comprised of 10% of fallers (n = 16) and a proportionate subsample of non-fallers (n = 85) from the original dataset.

Results

Three predictive models were developed. The best model (0.762 receiver operating characteristic[ROC] curve area, 60.4% accuracy, 68.8% sensitivity, 58.8% specificity) identified age (odds ratio[OR]=1.06[95%CI: 1.02, 1.10], P = 0.002), Michigan Neuropathy Screening Instrument score (OR=1.23[95%CI: 1.08, 1.40], P = 0.001), and self-reported balance problems (OR=2.65[95%CI: 1.29, 5.45], P = 0.008) as predictors of falls. A second model with good performance parameters (0.750 ROC curve area, 62.4% accuracy, 62.5% sensitivity, 62.4% specificity) showed that age (OR=1.04[95%CI: 1.01, 1.07], P = 0.015), balance problems (OR=3.29[95%CI: 1.64, 6.59], P = 0.001), and DPN severity (OR=1.18[95%CI: 1.03, 1.34], P = 0.018) were predictors of falls.

Conclusions

We showed the potential of a predictive model for recurrent falls based on commonly evaluated variables in community-dwelling individuals with diabetes for use in clinical practice. Even for individuals who are not at a high risk for falls, it is crucial to assess the combination of DPN signs, symptoms, and severity and the perception of balance problems, as these are more relevant in people with diabetes than the traditional physical impairments associated to aging.

Knowledge, attitudes, and barriers to HIV testing among youth in Kumba, Cameroon: A cross-sectional qualitative community-based focus group study

by Frederick Nchang Cho, Marie Clarie Fien Ndim, Diane Zinkeng Tongwa, Christabel Afor Tatah, Franklin Ngwesse Ngome, Eugine Mbuh Nyanjoh, Andrew N Tassang

Background

Human Immunodeficiency Virus (HIV) remains a major public health concern in sub-Saharan Africa. In Cameroon, young people are disproportionately affected but underrepresented in HIV testing statistics.

Objective

To explore knowledge, attitudes, and behaviours related to HIV testing among youth in Kumba, Cameroon, and to identify barriers to inform community-based interventions.

Methods

A cross-sectional qualitative study was conducted using nine focus group discussions (FGDs) with 75 youth (52 females and 23 males) aged 18 - 35 years across four quarters in the Kumba II municipality. Participants were purposively sampled to reflect diverse educational and occupational backgrounds. Data were thematically analysed using Braun and Clarke’s framework with NVivo Version 14.

Results

Participants demonstrated high awareness of HIV testing services (90.7%) and transmission via sexual contact (96.0%), though knowledge gaps remained regarding non-sexual transmission and testing procedures. While 93.3% had previously undergone HIV testing, 57.3% reported stigma and 46.7% raised confidentiality concerns as ongoing barriers. Female participants feared being labelled as promiscuous, while males cited social norms that discourage help-seeking. Most participants supported school-based or youth-centred community testing, emphasising the need for privacy and youth-friendly environments. Key motivators for testing included the desire to know one’s status (82.7%), symptom appearance (28.0%), and unprotected sex (17.3%).

Conclusions

Despite strong awareness and high testing uptake, stigma and confidentiality concerns persist among youth in Kumba. To enhance HIV testing rates, community-based strategies should prioritise mobile clinics, peer outreach, and confidential youth-centred services. Strengthening education about HIV transmission and demystifying the testing process may further reduce barriers.

Quantifying cross-sectional and longitudinal associations in mental health symptoms within families: network models applied to UK cohort data

Por: Bai · Y. · Rayner · A. · Abel · K. M. · Cartwright-Hatton · S. · Wan · M. W. · Pierce · M.
Objectives

Families offer promising targets for mental health interventions. Existing evidence investigates parent-child dyads or partners; we use an innovative approach to look at triads of parents and their children. This gives us more detail on mental health dimensions and individuals central to mental health transmission in families.

Design

Both cross-sectional and longitudinal network models

Setting

We identified triads of children (under age 16), mothers and fathers from the UK Household Longitudinal Study, between 2009 and 2022.

Participants and methods

Cross-sectional networks captured independent associations between family members’ mental health (n=8795 families). Longitudinal networks examined directional temporal associations among family members’ emotional symptoms (n=3757 families).

Primary outcome measures

Children’s and parents’ mental health dimensions were assessed using the Strengths and Difficulties Questionnaire and the General Health Questionnaire, respectively.

Results

Mothers’ mental health, particularly emotional symptoms, was linked to children’s mental health, while fathers’ symptoms showed no independent association. In the longitudinal network, maternal feelings of being overwhelmed were associated with children’s future worry, affecting symptoms of nervousness and unhappiness, which then fed back into worsening maternal emotional symptoms.

Conclusions

Investigating family mental health using network models highlights mothers’ central role. The longitudinal relationship between maternal feelings of being overwhelmed and children’s anxiety, and the subsequent feedback into maternal anxiety, indicates a promising target for intervention.

Development and validation of clinical vignettes to inform an educational intervention for physiotherapists to detect serious pathologies: a mixed-methods study

Objectives

To develop and validate educational clinical vignettes (CVs) based on real-life patients with serious pathology from the disciplines of oncology, internal medicine and orthopaedics that are relevant for physiotherapists (PTs) working in a non-direct access system.

Design

A mixed-methods study using an iterative design was employed to develop and validate CVs that focused on serious pathology.

Setting

Academic and clinical settings within health faculties at three universities in Austria and the UK.

Participants

Medical doctors (MD) (n=3) and PTs (n=4) developed CVs in the disciplines of internal medicine, oncology and orthopaedics. Validation of the CVs was undertaken in three stages: internal validation by the research team (n=7), external validation by MDs (n=3) and external validation by PTs (n=18).

Results

25 CVs focusing on internal medicine (9), oncology (8) and orthopaedics (8) were developed. Results of the consensus method of Haute Autorité de Santé ranged between 7 and 9 in the internal validation stage. In the external validation stage with MDs, one orthopaedic CV was excluded, resulting in a final total of 24 validated CVs.

Conclusions

This is the first time educational CVs have been developed and validated across such a broad range of pathologies for countries without direct access to physiotherapy, for use in the education of PTs. Furthermore, the approach described in the Methods section of this paper may serve as a template in similar future projects.

Adolescents and young adults (AYAs) in low- and middle-income countries (LMICs) are at high risk of harmful sexual and reproductive health (SRH) practices due to limited knowledge, low availability or acceptability of modern contraceptives, gender inequality and cultural practices like child marriage. Preventive and educational interventions by lay health workers or through technological means are a cost-effective and scalable solution. Unfortunately, too little is currently known about the scope, content and conditions of the effectiveness and sustainability of these approaches and synthetic evidence on this topic is scarce. To help fill this knowledge gap and to identify where further research is needed, we will conduct a scoping review of technology-based or lay health-worker delivered preventive and educational SRH interventions targeting AYAs in LMICs. This information is valuable to both policymakers and researchers as it provides a synthesis of existing interventions, highlights best practices for their implementation and identifies potential avenues for future research.

Methods

This review will include studies on SRH preventive and educational interventions targeting AYAs aged 10–24 years in LMICs. It encompasses interventions delivered by lay health workers or via technological means, assessing various outcomes including but not limited to SRH literacy, sexual risk behaviours, pregnancies, sexually transmitted infections and gender-based violence. Key databases, including PubMed via MEDLINE and Embase, will be searched from 1 January 2000 up to 23 January 2024, using a comprehensive search strategy. Screening will be conducted using Covidence software. Data extraction will cover study details, methods, intervention strategies, outcomes and findings. A narrative synthesis will be conducted following synthesis without meta-analysis guidelines.

Ethics and dissemination

The scope of this scoping review is limited to publicly accessible databases that do not require prior ethical approval for access. The findings will be disseminated through peer-reviewed journal publications, as well as presentations at national and international conferences and stakeholder meetings in LMICs.

Scoping review registration

The final protocol is prospectively registered with the Open Science Framework on 7 May 2024 (osf.io/vna2z).
