Exercise therapy is the most recommended treatment for chronic low back pain (LBP), with evidence supporting modest effects, likely due to the heterogeneity of patient presentations. Evidence suggests that matching individuals to the most appropriate exercise type could improve outcomes. Systematic reviews also emphasise that effective exercise interventions should be patient centred, target paraspinal muscle health and be of sufficient duration. This study addresses these gaps using a targeted care approach to identify a homogenous sample that is more likely to respond to our interventions. The inclusion of a sample with predominant nociceptive pain profile will be performed with the integration of the Pain and Disability Drivers Management Model (PDDM) and the Lumbar Spine Instability Questionnaire (LSIQ). The primary aim of this two-arm randomised controlled trial is to compare the effectiveness of motor control plus isolated lumbar extension exercises (MC+ILEX, arm 1) to free-weight resistance training (arm 2) in reducing LBP-related disability. Secondary aims include examining whether changes in multifidus composition mediate disability improvements comparing intervention effects on muscle size and quality, strength, mobility, pain, quality of life, sleep, physical activity and satisfaction; exploring baseline LSIQ scores and sex/gender as moderators of treatment response; and investigating participants’ perceptions and experiences of exercise therapy.

A total of 106 participants will be recruited through primary and secondary care and randomised (1:1) to receive either MC+ILEX or free-weight resistance training. Both groups will complete 48 exercise sessions over 16 weeks. The primary outcome will be disability at 16 weeks, measured by the Oswestry Disability Index. Secondary outcomes include multifidus muscle composition and size, lumbar and gluteal muscle strength, hip range of motion, pain, physical and mental function, satisfaction and recovery, health-related quality of life, sleep quality and physical activity levels. Linear mixed-effects models will be used to assess primary and secondary outcomes. Regression analyses will explore whether baseline LSIQ scores moderate treatment effects on multifidus composition and other outcomes. A subsample of participants will undergo semistructured interviews before and after the intervention to explore their illness perceptions, illness mindsets, perceptions of exercise therapy, as well as their experiences and satisfaction with the two exercise interventions. Reflexive thematic analysis will be used to analyse qualitative data.

This study received ethics approval from the Central Ethics Research Committee of the Quebec Minister of Health and Social Services (CCER-25-26-14). Results will be submitted to peer-reviewed journals and scientific meetings.

The aims of this study were (1) to develop and validate the interactive CLAIM Test (iCLAIM Test) to measure children’s ability to assess claims about treatment effects and make informed health choices and (2) to measure this ability in Spanish primary school children using the developed test.

We followed a multistep process including (1) definition of the test scope, (2) selection of the questions, (3) translation process, (4) design and development of the online test, (5) external review with experts, (6) user-test with children and (7) cross-sectional validation study with Rasch analysis.

Spanish primary schools.

Twelve experts (75% women) participated in the review, 11 children (45% girls) participated in the user-test and 480 Spanish primary school children (46.5% girls) from fourth to sixth grades (9–12 years old) participated in the cross-sectional validation study.

The iCLAIM Test is an online, interactive and user-friendly test in Spanish that measures children’s ability to understand and apply key concepts of the informed health choices (IHC) Project when assessing claims about treatment effects and making IHCs. The test includes 30 questions: six demographic questions and 24 questions from the Claim Evaluation Tools item bank. Less than 40% of the students who participated in the cross-sectional validation study showed basic knowledge of the IHC Key Concepts and how to apply them, and less than 4% showed a clear knowledge. The test showed a good fit to the Rasch model and was acceptable to the target audience.

The iCLAIM Test is the first instrument validated for measuring children’s ability to assess treatment claims in Spain. In the future, we can tailor IHC education interventions and improve critical thinking skills about the health of Spanish children.

To understand the political, economic, social and technological facilitators and barriers in obtaining an HIV diagnosis to inform implementation strategies for HIV diagnostics in the Dominican Republic (DR).

In-depth, semi-structured qualitative interviews.

A high complexity public hospital in Santiago de los Caballeros, DR.

A convenience and purposive sample of 36 internal medicine physicians and laboratory personnel involved in sample collection, sample analysis or oversight of biological sample analysis.

Using the Social Ecological Model, our results highlighted several interrelated barriers and facilitators to sample analysis at the individual (patient), interpersonal (interactions between laboratory personnel, physicians and patients), organisational (the hospital), community (Santiago de Los Caballeros) and societal (the DR) levels. Some key findings include the importance of psychological support in receiving an HIV diagnosis, how spoken language can be a barrier to care, how inconsistent access to laboratory supplies is a barrier for patients, laboratory personnel and clinicians, and the importance of government public health investment.

Employing qualitative methods to investigate a bioengineering challenge yielded rich data on the sociotechnical implementation context of HIV diagnostics in the DR. Several context-relevant suggestions were developed for HIV diagnostic developers which include incorporating psychological support into the diagnosis workflow, delivering information in multiple languages (ie, Haitian Creole and Spanish) and with non-stigmatising phrasing, working with the public sector to develop and implement technologies, and reducing the supply chain reliance on high-income countries to lessen delays in care. These findings can apply to other types of health technologies and settings and demonstrate the importance of utilizing human-centered design to understand implementation context and promote global health equity in health technology development and adoption.

Childhood overweight and obesity pose a growing public health problem with increasing prevalence both in Europe and globally. Reasons can be found in behavioural factors such as a sedentary lifestyle, eating habits or low exercise levels and to a lesser extent in a genetic predisposition or a metabolic disorder. Preventing children with obesity and overweight to grow into obese teenagers is therefore of high importance. However, there are currently no established care and prevention programmes in Germany for the early reduction of overweight and prevention of obesity in children aged 3–6 years. fruehstArt aims to close this gap with a cross-sector outreach and family-centred personal counselling approach, where parents receive support from paediatricians and trained coaches who conduct consultations in the home of the family. The main research question is whether the fruehstArt programme reduces overweight and obesity in children aged 3–6 years within 12 months, as measured by the body mass index-standard deviation score (BMI-SDS).

fruehstArt has been developed as a new form of care, which includes a family intervention with motivational interviews provided by paediatricians and individual home-based counselling provided by a trained coach on eating behaviour, exercising, sleeping behaviour and age-appropriate use of electronic devices. fruehstArt will be accompanied by an efficacy study (summative evaluation of change in BMI-SDS). In addition to German, the project is also offered in Turkish in order to reach families with a migration background and language barriers. 812 children with overweight or obesity and their families in the region North Rhine will be included and observed over 12 months. Recruitment of children occurred from December 2023 to April 2025 with the final visits scheduled for April 2026. The study is conducted as a randomised controlled trial with a social-ecological intervention approach, considering children in their living environment and conditions. Moreover, a formative evaluation at the process level, and the system level will be carried out and complemented by a health economic analysis. Those are carried out to provide information about the intervention’s success and relevant costs. Thus, fruehstArt is realised in the form of an effectiveness–implementation hybrid design that combines the analysis of effectiveness with an evaluation of the implementation process.

The study received ethics approval in a coordinated procedure from the ethics committee of the Medical Faculty University hospital of Cologne and the ethics committee of the North Rhine Medical Association. For all collected data, the relevant national and European data protection regulations will be considered. All personal data (contact details) will be removed for the data analysis in order to ensure pseudonymisation. Dissemination strategies include reports and quality workshops for organisations, peer-reviewed publications and the presentation of results at conferences.

The aim of the unique form of care fruehstArt is to improve the care of preschool children with overweight or obesity through innovative home-based counselling, cross-sectoral service integration and to address the cultural needs of Turkish families.

In Indonesia, the second most natural disaster-prone country in the world, the tobacco industry exploits such crises via corporate social responsibility. The objective of this study was to map existing evidence on natural disasters and tobacco use in order to understand how tobacco control policies could be optimised in disaster-prone regions.

Scoping review.

ScienceDirect, PubMed and Google Scholar, with searches conducted twice: between January and April 2024 and again in August 2025.

All studies examining natural disasters, smoking behaviours and the tobacco industry.

Studies were assessed primarily on reports of tobacco use change, tobacco control policy enforcement, tobacco industry interference and mention of the role of stress. Data on country, disaster type, type of research study and sample details were also collated.

27 of the 611 identified studies were included in the final analysis. Two-thirds of studies reported an increase in smoking rates following disasters. No studies mentioned tobacco control policy enforcement or tobacco industry interference during disasters. Most of the studies (74%) which examined the relationship between disaster-related stress and smoking found a positive association. About half (51.9%) of the studies described disasters in the Americas.

Smoking rates often rise after stress-inducing disasters. More evidence is urgently required to assist countries like Indonesia in enforcing tobacco control and preventing tobacco industry interference.

The WHO Safe Childbirth Checklist (SCC) has been implemented in diverse settings to improve the quality and safety of intrapartum care, but implementation strategies and their relationship with adoption and fidelity remain heterogeneous and incompletely described.

To describe the landscape of SCC implementation, map the implementation strategies used and explore how these strategies were reported in relation to adoption and fidelity.

We included primary studies reporting SCC implementation in healthcare settings that described at least one implementation strategy, with no restrictions on country or language. Studies that did not report implementation strategies or did not involve SCC use in real-world care settings were excluded.

We searched PubMed, Embase, CINAHL, Global Health and Global Index Medicus (June 2024), screened reference lists and consulted grey literature for the period 2009–2024.

This scoping review followed JBI methodology (Peters et al) and was reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews. We extracted study characteristics and implementation findings, coded strategies using the Expert Recommendations for Implementing Change (ERIC) taxonomy and grouped them by clusters. Adoption (initial uptake) and fidelity (adherence to core components) were categorised following Proctor’s implementation outcomes. We created a descriptive implementation intensity score and conducted exploratory analyses (tertiles, boxplot).

34 studies described 19 SCC implementation projects across 16 countries. We identified 24 distinct ERIC strategies, with most projects using 5–11 strategies. Frequently reported strategies included educational meetings, audit and feedback, supervision, contextual adaptation and leadership or champions. Exploratory analyses did not show consistent associations between implementation intensity and adoption or fidelity. ‘Change infrastructure’ strategies (such as record system or equipment changes) were variably defined and warrant cautious interpretation. Adaptations (eg, translation and alignment with national guidelines) were common and aimed at improving local fit, but heterogeneous reporting limited cross-study comparability.

SCC implementation has relied on diverse, multicomponent strategies, yet reporting—especially of strategy content and adaptations—remains insufficient, constraining comparison and synthesis across settings. As a pragmatic bundle, implementers may prioritise brief team training, unit-level champions and leadership signals, point-of-care audit and feedback, light-touch SCC adaptation that preserves core content and structured supervision or peer coaching, combined with systematic inclusion of women and families through codesign and companion-mediated prompting. Using theory-informed frameworks (such as Exploration, Preparation, Implementation, and Sustainment and Consolidated Framework for Implementation Research [CFIR]) and standardised reporting tools (eg, Proctor’s outcomes; Template for Intervention Description and Replication / Standards for Reporting Implementation Studies [TIDieR/StaRI]) can make SCC implementation strategies more transparent, comparable and scalable.

Respiratory infections like influenza and SARS-CoV-2 pose significant global health risks due to their high transmissibility and severity. SARS-CoV-2 has caused over 7 million deaths worldwide, and the Lancet Commission estimates a >20% chance of a similar respiratory virus pandemic within a decade. Schools, often poorly ventilated, are high-risk settings for transmission. While COVID-19 school closures may have reduced transmission, they likely caused learning loss, mental health issues and increased burdens on parents and caregivers. Air purifiers with High Efficiency Particulate Air (HEPA) filters may offer a non-disruptive mitigation strategy, but the evidence to support their effectiveness in reducing viral transmission is weak. This protocol describes a cluster-randomised, parallel, two-arm, group sequential superiority trial with an interim analysis—to allow early stopping for efficacy or futility—to estimate the effect of portable air purifiers with HEPA filters in primary school classrooms on student absenteeism.

This group sequential trial will randomise schools (clusters) 1:1 to intervention or control arms in two stages: winter 2025/2026 (N=32 schools; ~736 students) and winter 2026/2027 (N=30 schools; ~690 students). The study setting is Norway. Eligible schools must have classrooms suitable for portable air purifiers, >10 students in grades 5–7 (typically aged 10–13 years) and principal consent. Intervention and control classrooms will each receive two portable air purifiers with HEPA filters operating at a performance equivalent to 3.0 and 0.3 air changes per hour, respectively, with control purifiers acting as shams. Outcomes will be measured during and at the end of a 12-week period. The primary outcome is student absenteeism, measured as full child days of absence aggregated at the class level. An interim analysis is planned at the end of the first stage, with error-spending O’Brien-Fleming stopping boundaries that are binding for efficacy and non-binding for futility. The primary estimand is the marginal incidence rate ratio of student absences, estimated using generalised estimating equations with a negative binomial model to account for overdispersion. Prespecified stopping boundaries will determine stopping, with efficacy boundaries being binding. Treatment effects will be estimated using cluster-bootstrapped CIs adjusted to provide strong control on overall type I and II error probabilities, and a bias correction will be applied if the trial is stopped early for efficacy. All analyses will follow the intention-to-treat principle. The primary question is whether installing and operating air purifiers with HEPA filters (intervention) reduces student absenteeism due to sickness (primary outcome) compared with sham air purifiers (control). Secondary questions examine whether the intervention reduces teacher absenteeism due to respiratory infections, rate and 12-week risk of self-reported respiratory infections among teachers, and teachers’ perceptions of air quality, compared with sham air purifiers. If the trial estimates a statistically significant effect for the primary outcome, a cost-consequence analysis will evaluate the direct and indirect costs associated with operating air purifiers against the potential benefits of reduced student and teacher absenteeism. A process evaluation will explore mechanisms of effect.

The trial has been approved by the Regional Committees for Medical and Health Research Ethics and the National Research Ethics Committee (ref. 737650). Absence data, routinely collected and fully anonymised at the class level, will serve as the primary outcome and does not require informed consent. Informed consent will be obtained from teachers participating in weekly surveys or interviews. Results will be disseminated to stakeholders, participants and the public through peer-reviewed journals, scientific meetings and social media.

NCT07119333.

The primary objective of this clinical trial is to determine the clinical and cost-effectiveness of psychoeducation and emotional stabilisation (PES), together with eye movement desensitisation and reprocessing (EMDR) plus treatment-as-usual (TAU) in reducing symptoms of post-traumatic stress disorder (PTSD) among adults with intellectual disabilities compared with TAU. Secondary objectives include: (1) determining whether PES/EMDR plus TAU is superior to TAU in improving mental health problems and quality of life (QoL) among adults with intellectual disabilities who had a diagnosis of PTSD and (2) completing a process evaluation to examine intervention implementation and acceptability.

This is a two-arm parallel single-blind randomised controlled trial comparing PES-EMDR+TAU to TAU including an internal pilot phase. Outcome data will be captured prior to randomisation, and at 4 (after PES), 8 (after EMDR) and 14 months postrandomisation by masked assessors. 144 adults with intellectual disabilities with a diagnosis of PTSD will be allocated (1:1) randomly using minimisation from National Health Service (NHS) community and inpatients services for adults with intellectual disabilities in England. Participants are eligible to take part in this trial if: (1) they are aged 18 or older, but younger than 66, (2) have a Full Scale IQ

The primary outcome will be assessed using an intention-to-treat analysis. Baseline characteristics will be compared between arms to determine whether any potentially influential imbalance occurred. The primary outcome will be analysed by analysis of covariance, adjusting for baseline values of the outcome and any variables used in the randomisation process. Secondary outcomes will be analysed using linear or logistic regression models as appropriate reflecting the distribution of the outcome variable. The treatment effect will be estimated as an adjusted difference between sample means, presented with 95% CIs and p values. A complier average causal effect analysis will be considered should the data availability be sufficient to estimate the impact of non-compliance. A series of subgroup analyses on the primary outcomes will be considered considering differences in the Impact of Event Scale–Intellectual Disabilities scores at 14 months for (1) differing levels of general intellectual functioning and (2) PTSD versus complex PTSD.

This clinical trial was designed to allow for conclusions about whether PES/EMDR+TAU is efficacious in reducing symptoms of PTSD, relative to TAU, for adults with intellectual disabilities. A favourable ethical opinion has been received from an NHS ethics committee in the UK. The findings from this trial will be published within peer-reviewed journals and shared at national and international conferences. We will also aim to record and distribute podcasts detailing our findings together with our partners.

There is limited research exploring the age-related difference in communication when describing pain experiences. This project aimed to identify key differences between adolescents’, young adults’ and adults’ (i) preferred communication method, (ii) language content and (iii) lexical amount and variety when discussing their persistent pain experience using chatbot technology.

An exploratory concurrent nested mixed-methods design using a comparative analysis.

Participants were recruited through a convenience sampling strategy from two tertiary multidisciplinary pain centres in Australia.

20 adolescents, 20 young adults and 20 adults completed a pain history assessment using the Dolores application. The inclusion criteria for this study were (i) persistent non-cancer pain for at least 3 months, (ii) 10 years of age and over and (iii) adequate expressive and receptive language skills to complete the required tasks in English, as determined by clinicians in the treating team.

Drawn, voice and typed responses provided by participants during the chatbot interaction were analysed using content analysis. Fisher’s exact tests and ² tests were used to examine differences between age groups. Strong effect size estimates generated from comparative analyses suggested that adolescents were the most likely age group to utilise drawing (p=0.153, Cramer’s V=0.268), preferred typing over speaking (p==0.007, Cramer’s V=0.433). Young adults used the greatest number and variety of words in response to chatbot questions including evaluative language (p=0.097, Cramer’s V=0.296). Adults tended to use more metaphors (p=0.085, Cramer’s V=0.305) and had a strong preference for speaking over typing (p=

The results of this study provide insights into age-related differences in communication and preferences when using technology to communicate about persistent pain. Future research exploring individualised age-related approaches to pain assessment, supported by the findings of this study, in comparison to current standardised assessments administered by clinicians are warranted.

This study aims to develop a robust, targeted measure of patient experiences of person-centred care (PCC), informed by the lived experiences of patients with chronic illness using the psychometric theory of Rasch measurement.

The Rasch measurement model was used to analyse the psychometric functioning of 57 candidate items and select appropriate items for a targeted measure.

Participants were recruited from Prolific.com, having experience of both chronic or long-term illness and first-hand experience of primary or secondary care in the UK healthcare setting and completed a survey containing PCC items and descriptors of healthcare experience.

Data from 501 adult persons (49.5% men and 49.7% women) with different types of long-term conditions recruited from the prolific web panel.

For an initial analysis of all 57 candidate items, there were several indicators of misfit, such as signs of local dependence and multidimensionality. The response options worked as intended according to threshold ordering. After removal of misfitting items and refinement for the best spread of locations, a 14-item solution showed good fit to the Rasch model in this UK sample.

The results support a unidimensional measurement of patients’ experiences of PCC, once the local dependency was accommodated. The present work thus offers a 14-item measure of PCC experience. The present work also contains a robust item bank for the further development of dynamic computerised adaptive testing.
