Implementation science (IS) is increasingly recognised as vital in cancer control planning and integrating evidence-based interventions across the cancer care continuum. Contextual differences often cause variability in delivering optimised healthcare, which IS approaches could mitigate. While IS improves planning effectiveness, many programme and policy planners remain unaware of its benefits. To address this, we examined IS theories applied to national cancer control plans (NCCPs)/strategies across five domains: stakeholder engagement, situational analysis, capacity assessment, economic evaluation and impact assessment.

We conducted a scoping review using the Arksey and O’Malley framework to analyse NCCPs and strategies from 16 and 17 countries belonging to low and medium categories of Human Development Index (HDI), focusing on resource-constrained settings. We identified plans through the International Cancer Control Partnership portal, categorised them by WHO region and included only those available in English or French. We extracted data into a Microsoft Excel database and performed thematic analysis across five IS domains. Multiple IS experts, selected purposively based on their familiarity with resource-constrained settings, validated the findings, assessed policy relevance and helped develop a pathway for integrating IS into national cancer control planning. They reviewed structured questions in advance and provided feedback on analyses, practical utility, dissemination and simplifying IS application, which was used to refine the pathway and reach consensus.

While many NCCPs incorporated key IS elements such as stakeholder engagement, situational analysis and impact measurement, these often needed to be more explicit and consistently applied. None of the plans assessed health system capacity to determine readiness for implementing new interventions. Although most plans described stakeholder engagement, it was typically unstructured and incomplete. Four low HDI and nine medium HDI countries included costed plans, generally using an activity-based approach. All plans included impact measures (eg, key performance indicators), but five lacked mechanisms for engaging stakeholders or responsible entities to achieve the targets. These findings informed a proposed pathway to integrate IS principles into cancer control planning.

Integrating IS into national cancer control planning offers a structured framework for achieving equitable and feasible cancer control policies, particularly in resource-constrained settings, by enabling realistic goal setting and benchmarking against regional and global standards.

The predisposition to food allergy development and the induction of allergen-specific immune responses appears to be initiated early in infancy. Early exposure to food allergens, such as peanut and cashew nut, via human milk is likely important in initiating oral tolerance and reducing risk of food allergy development. This trial aims to determine if the risk of developing peanut and cashew nut allergy during infancy can be reduced by a high peanut and cashew nut maternal diet during lactation.

This is a multisite, parallel, two-arm (1:1 allocation), single-blinded (outcome assessors, statistical analyst and investigators), randomised controlled trial. Target sample size is 4412 participants (2206 per group). Women (aged 18–50 years) with a singleton pregnancy, who are planning to breastfeed and do not have peanut and/or cashew nut allergies are eligible to participate. After obtaining written informed consent, participants are randomised to either a high peanut and cashew nut diet (at least 60 peanuts and 40 cashew nuts per week) or a low peanut and cashew nut diet (no more than 20 peanuts and 12 cashew nuts per week). Participants are asked to follow their allocated diet from birth to 6 months postnatal. Individual lactation consultant advice and support is provided as required. The study’s primary outcome is food challenge proven IgE-mediated peanut and/or cashew nut allergy during infancy (0–18 months). Key secondary outcomes include infant sensitisation to peanut and/or cashew nut. Analyses will be performed on an intention-to-treat basis according to a prespecified statistical analysis plan.

Ethical approval has been granted from the Western Australian Child and Adolescent Health Service Human Research Ethics Committee (approval number RGS0000006685). Trial results will be presented at scientific conferences and published in peer-reviewed journals.

Most clinical practice guidelines (CPGs) for assessing and managing people’s chronic pain focus on specific pain conditions, body sites or life course stages. This creates complexity for clinicians making care choices in the absence of a diagnosis and/or where a person experiences more than one pain condition. Specific to this context is the ICD-11 classification of chronic primary pain where an experience of pain cannot be better accounted for by another condition. CPGs for chronic primary pain, agnostic to condition or body part, may support clinicians towards best pain care since many of the principles of person-centred chronic pain care are transdiagnostic. The two aims of this systematic review are to (1) identify and appraise CPGs for chronic primary pain, relevant across the life course and (2) map the CPG content against a pain care priority framework to evaluate the extent to which the CPG content aligns with the priorities of people with lived chronic pain experience.

We will systematically search nine scholarly databases, the Epistemonikos database and international and national guidelines clearinghouses. CPGs published within 2015–2025, in any language, that offer recommendations about assessment and/or management of chronic primary pain for people of any age, excluding hospitalised inpatients or institutionalised populations, will be included. Pairs of reviewers will independently screen citations for eligibility and appraise CPG quality and implementation potential using the Appraisal of Guidelines for Research and Evaluation (AGREE)-II and the AGREE-Recommendations Excellence tools, respectively. Data extraction will include the citation and scope characteristics of each CPG, methods used to develop recommendations, verbatim recommendations, guiding principles or practice information and narrative excerpts related to the GRADE Evidence-to-Decision (EtD) considerations (or equivalent). We will use the PROGRESS-PLUS framework as a checklist to identify whether determinants of health equity were considered by guideline developers. CPG recommendations will be organised according to common topics and categorised in a matrix according to strength and direction. Qualitative content analysis will be used to synthesise excerpts relating to GRADE EtD considerations (or equivalent), and we will map extracted data against an established chronic pain care priority framework to determine the extent to which the CPGs align with values and preferences of people with lived experience. Interpretation will be informed by an interdisciplinary Advisory Group, including lived experience partners.

Ethical approval is not required for this systematic review. Results will be disseminated through publication in an open-access peer-reviewed journal, through professional societies, and integrated into education curricula and public-facing resources. Reporting will be consistent with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement.

To identify views and establish agreements of key stakeholders on the features of an effective system for declaring and managing conflicts of interest in healthcare.

A modified Delphi study consisting of two surveys and semi-structured interviews. Surveys included closed and free-text questions.

UK, purposefully and generally invited participants including academics, researchers, healthcare professionals, regulators, patients and citizens from 10 countries, during 25 August 2024 and 20 January 2025.

Quantitative and qualitative analysis of two surveys and 21 interviews. Descriptive statistics were used to describe the sample and analyse closed survey questions. Thematic analysis was used to analyse free-text survey responses and interview data. Results were synthesised to describe the perceived importance and purposes of declaration of interest systems.

In the first survey round, 616 invitations were sent, along with social media advertisements. 237 questionnaires were returned and 200 full responses were analysable. 129 respondents consented to recontact on the online form. In the interview round, 37 invitations were sent and 21 interviews completed (response rate 59.5%). Invitations for the second survey were sent to all 129 participants who consented to recontact. 91 responses were received and 89 questionnaires were analysable (response rate 82%). Features of ideal systems to declare and manage the interests of healthcare professionals identified by participants were categorised under seven themes: regulatory issues, the healthcare environment, human vices, professional virtues, the use of judgement, features of a better system and patients and public. There was broad agreement on the need for transparency and clarity in declaration systems. The most agreed features were: clarity on what information was needed; it should be a centralised ‘deposit’ for all declarations; it should be publicly accessible, educating and informing people accessing and using the register. Having a lifelong personal identifier, some flexibility in declarations and some privacy features were also rated highly. Respondents were less concerned about scrutiny or a loss of trust. Small numbers of participants raised concerns about serious adverse effects, including loss of privacy, personal safety and the potential of information to contribute to conspiracy theories. There were also major disagreements between participants concerning whether or not healthcare professionals should work with industry, and whether conflicts of interest from working with industry can be safely managed. Individuals with each perspective felt they were acting ethically.

While many agreements were identified, disagreements were also found. If improved declaration systems are to be accepted by professionals and useful to regulators, patients and citizens, the potential for benefit and harm from new declaration systems must be addressed.

Canadian guidelines recommend HIV testing for individuals being evaluated for syphilis. Our objective was to examine three aspects of HIV testing (ie, if an HIV test occurred, the timing of the HIV test in relation to the syphilis test and the proportion with a positive HIV test result) among syphilis tests between 2017 and 2022 from individuals with no evidence of a previous HIV diagnosis.

This study is a retrospective analysis of comprehensive laboratory testing data from Ontario’s provincial public health laboratory.

Direct fluorescent antibody (DFA) and serological non-prenatal syphilis tests were conducted from 1 January 2017 to 31 December 2022, from individuals aged ≥15 years with no evidence of a previous HIV diagnosis (n=3 001 058 total tests). Positive syphilis tests were categorised using the rapid plasma reagin (RPR) titre as ‘current’ (DFA+/RPR≥1:8) or ‘historical’ (RPR

The number and proportion of syphilis tests with a corresponding HIV test on the same day or within 7, 28, 90 or 180 days, and, among those with an HIV test within 28 days, the number and proportion with an HIV-positive test result.

From 2017 to 2022, 1 516 726 and 1 484 332 syphilis tests among males and females, respectively, were included in the analysis. Individuals with a positive syphilis result were less likely to be tested for HIV within 28 days of their syphilis test compared with those with a negative syphilis test result (74.7% vs 91.1% in males, 97.5% CI (–0.17 to –0.16); 65.2% vs 92.4% in females, 97.5% CI (–0.28 to –0.26)). Males with ‘current’ positive syphilis test results were less likely than males with ‘historical’ positive syphilis results to be tested for HIV within 28 days (69.1% vs 76.6%, 97.5% CI (–0.084 to –0.066)); this was not true in females (67.1% vs 64.4%, 97.5% CI (0.0062 to 0.049)). Males overall and males with ‘current’ syphilis were more likely to be diagnosed as HIV-positive (p

Most individuals who tested for syphilis at Public Health Ontario were also tested for HIV; however, those who tested positive for syphilis were less likely to be tested, representing an opportunity for enhanced HIV testing. Ensuring that individuals with syphilis are tested for HIV may help identify previously undiagnosed individuals living with HIV.

To describe: (1) the most visible information (from individuals or organisations) on UK social media regarding hormone replacement therapy (HRT)/menopause hormone treatment for menopause; (2) claims made by these sources for HRT and testosterone outwith the indications specified by the British National Formulary (BNF) and the National Institute of Health and Care Excellence (NICE) (ie, vasomotor instability, vaginal dryness, low mood associated with the menopause and, for testosterone, low libido after treatment with HRT) and for use for the prevention of future ill health and (3) conflicts of interest of commentators.

Cross-sectional study.

Online references to HRT, for use in menopause, in UK online media, comprising Facebook, Google, Instagram, TikTok and YouTube, 30 top ranked hits between 1 January 2022 and 1 June 2023 and Twitter (X) up to 1 May 2024.

Identification of the most visible information was performed via online searching with the term ‘HRT’ using incognito searches within each modality. Statements making claims were identified and analysed as to whether they were congruent with BNF and NICE advice on indications for use. Declarations of interest were extracted from the source or searched for if not apparent using a standardised search strategy. Data were entered into an Excel spreadsheet. Summary and descriptive statistics were used to summarise the results, including description of origin and types of claims, percentage of claims in agreement with NICE/BNF indications, relationship to financial interests and readership data, where available.

180 recommendations and/or claims for HRT were examined (30 from each of six platforms), made by professional individuals (53.4%), laypeople (41.7%) and patient, media and professional organisations (4.9%) completing the total. Overall, 67.2% of claims were outside of BNF/NICE recommendations. 139 (77.2%) were associated with a conflict of interest. In 117 cases, this was a conflict either directly or indirectly related to menopause, through provision of private practice, pharmaceutical industry funding or retail products marketed at the menopause.

Social media commonly contains claims for HRT outside BNF/NICE guidance. Conflicts of interest by commentators are also common, directly or indirectly related to menopause. Less than a quarter of media contained no commercial conflict. Policymakers should consider means to ensure that non-conflicted, evidence-based information is visible to professionals, patients and the public.
