Abstract
BACKGROUND Clinical trials are essential to evidence-based medicine. Their success relies on recruitment and retention of participants: problems with either can affect validity of results. Past research on improving trials has focused on recruitment, with less on retention, and even less considering retention at the point of recruitment, i.e., what retention-relevant information is shared during consent processes. The behaviour of trial staff communicating this information during consent is likely to contribute to retention. So, developing approaches to mitigate issues in retention at the point of consent is necessary. In this study, we describe the development of a behavioural intervention targeting the communication of information important to retention during the consent process. METHODS We applied the Theoretical Domains Framework and Behaviour Change Wheel to develop an intervention aimed at changing the retention communication behaviours of trial staff. Building on findings from an interview study to understand the barriers/facilitators to retention communication during consent, we identified behaviour change techniques that could moderate them. These techniques were grouped into potential intervention categories and presented to a co-design group of trial staff and public partners to discuss how they might be packaged into an intervention. An intervention was presented to these same stakeholders and assessed for acceptability through a survey based on the Theoretical Framework of Acceptability. RESULTS Twenty-six behaviour change techniques were identified with potential to change communication of retention-information at consent. Six trial stakeholders in the co-design group discussed means for implementing these techniques and agreed the available techniques could be most effective within a series of meetings focussed on best practices for communicating retention at consent. The proposed intervention was deemed acceptable through survey results. CONCLUSION We have developed an intervention aimed at facilitating the communication of retention at informed consent through a behavioural approach. This intervention will be delivered to trial staff and will add to the available strategies for trials to improve retention.

How European Fans in Training (EuroFIT), a lifestyle change program for men delivered in football clubs, achieved its effect: a mixed methods process evaluation embedded in a randomised controlled trial. BMC Public Health 2023; 23:526.

Abstract
BACKGROUND A randomised trial of European Fans in Training (EuroFIT), a 12-week healthy lifestyle program delivered in 15 professional football clubs in the Netherlands, Norway, Portugal, and the United Kingdom, successfully increased physical activity and improved diet but did not reduce sedentary time. To guide future implementation, this paper investigates how those effects were achieved. We ask: 1) how was EuroFIT implemented? 2) what were the processes through which outcomes were achieved? METHODS We analysed qualitative data implementation notes, observations of 29 of 180 weekly EuroFIT deliveries, semi-structured interviews with 16 coaches and 15 club representatives, and 30 focus group discussions with participants (15 post-program and 15 after 12 months). We descriptively analysed quantitative data on recruitment, attendance at sessions and logs of use of the technologies and survey data on the views of participants at baseline, post program and after 12 months. We used a triangulation protocol to investigate agreement between data from difference sources, organised around meeting 15 objectives within the two research questions. RESULTS We successfully recruited clubs, coaches and men to EuroFIT though the draw of the football club seemed stronger in the UK and Portugal. Advertising that emphasized getting fitter, club-based deliveries, and not 'standing out' worked and attendance and fidelity were good, so that coaches in all countries were able to deliver EuroFIT flexibly as intended. Coaches in all 15 clubs facilitated the use of behaviour change techniques and interaction between men, which together enhanced motivation. Participants found it harder to change sedentary time than physical activity and diet. Fitting changes into daily routines, planning for setbacks and recognising the personal benefit of behaviour change were important to maintain changes. Bespoke technologies were valued, but technological hitches frustrated participants. CONCLUSION EuroFIT was delivered as planned by trained club coaches working flexibly in all countries. It worked as expected to attract men and support initiation and maintenance of changes in physical activity and diet but the use of bespoke, unstable, technologies was frustrating. Future deliveries should eliminate the focus on sedentary time and should use only proven technologies to support self-monitoring and social interaction.

Abstract
This paper investigated facilitators and barriers to implementing the European Football Fans in Training program (EuroFIT) in professional sports clubs in England, the Netherlands, Norway, and Portugal. We analyzed qualitative data collected at clubs that delivered EuroFIT, based on semi-structured interviews with coordinating staff (n = 15), coaches (n = 16), and focus group interviews with participants (n = 108), as well as data from clubs that considered delivering EuroFIT in the future, based on interviews with staff (n = 7) and stakeholders (n = 8). Facilitators for implementation related to the content and structure of the program, its evidence-base, and the context for delivery in the football stadia. Financial and human resources were both facilitators and barriers. Further barriers were mostly practical, relating to human resources and infrastructure. Major differences between countries related to experience and commitment to running community projects, and differences in infrastructure, financing, and human resources. Professional football clubs' ability to support health promotion efforts depended on their ethos and the financial and human resources available to them. Overall, the EuroFIT program was well received by clubs, coaches, participants, and stakeholders, which was reflected by the many facilitators supporting sustained implementation. For sustainable implementation, it is crucial that clubs and their stakeholders engage fully with the EuroFIT program and understand that for an adequate program delivery their views (ethos) and ways of working influence the implementation and thereby the effectiveness of EuroFIT. An important prerequisite for future roll out of EuroFIT would be a strong EuroFIT delivery partner organization to ensure financial and human resources while overseeing and guiding the quality of delivery in clubs.

Abstract
Neutrophil extracellular traps contribute to lung injury in cystic fibrosis and asthma, but the mechanisms are poorly understood. We sought to understand the impact of human NETs on barrier function in primary human bronchial epithelial and a human airway epithelial cell line. We demonstrate that NETs disrupt airway epithelial barrier function by decreasing transepithelial electrical resistance and increasing paracellular flux, partially by NET-induced airway cell apoptosis. NETs selectively impact the expression of tight junction genes claudins 4, 8 and 11. Bronchial epithelia exposed to NETs demonstrate visible gaps in E-cadherin staining, a decrease in full-length E-cadherin protein and the appearance of cleaved E-cadherin peptides. Pretreatment of NETs with alpha-1 antitrypsin (A1AT) inhibits NET serine protease activity, limits E-cadherin cleavage, decreases bronchial cell apoptosis and preserves epithelial integrity. In conclusion, NETs disrupt human airway epithelial barrier function through bronchial cell death and degradation of E-cadherin, which are limited by exogenous A1AT.

Abstract
Abstract
Background
Invasive coronary angiography and non-invasive viability testing are the cornerstones of diagnosing and managing ischemic left ventricular dysfunction. At present there is no single test which serves both needs but, if developed, could revolutionise investigation of this condition. Coronary wave intensity analysis (cWIA) interrogates both contractility and microvascular physiology of the subtended myocardium [1,2] and therefore has the potential to fulfil this goal.
Objectives
We hypothesized that cWIA measured during coronary angiography would predict functional recovery with a similar accuracy to late gadolinium enhanced cardiac magnetic resonance imaging (LGE-CMR).
Methods
Patients with a left ventricular ejection fraction ≤40% and extensive coronary disease were enrolled. cWIA, fractional flow reserve and microvascular resistance were assessed with a simultaneous coronary Doppler and pressure-sensing guidewire during cardiac catheterization at rest, during hyperaemia and during low-dose dobutamine stress. Viability was assessed using LGE-CMR. Regional left ventricular function was assessed at baseline and 6-month follow up after optimization of medical therapy +/− revascularization, using transthoracic echocardiography. The primary outcome was regional functional recovery.
Results
Forty participants underwent baseline physiology, LGE-CMR and thirty had echocardiography at baseline and 6 months; 21/42 territories demonstrated functional recovery. Resting backward compression wave energy was significantly greater in recovering than non-recovering territories (−5240±3772 vs. −1873±1605 W m–2 s–1, p=0.099, Figure 1), and had comparable diagnostic accuracy to CMR (area under the curve 0.812 vs. 0.757, p=0.649, Figure 2); a threshold of −2500 W mm–2 s–1 had 86% sensitivity and 76% specificity at predicting recovery. Backward expansion wave energy did not predict recovery. FFR was numerically higher in recovering territories (0.81±0.17 vs. 0.71±0.16, p=0.058), whilst hyperaemic microvascular resistance did not differentiate recovering from non-recovering territories (1.97±0.73 vs. 2.29±1.00, p=0.287). The likelihood of functional recovery was similar in revascularised and non-revascularised territories (15/29 vs. 6/13 respectively, p=0.739). Low-dose dobutamine stress increased the energy of all waves, but did not improve the accuracy of cWIA in predicting recovery. In a regression model, resting backward compression wave energy and optimization of medical therapy predicted functional recovery; fractional flow reserve and hyperemic microvascular resistance did not.
Conclusions
Backward compression wave energy has similar accuracy to LGE-CMR in the prediction of functional recovery. cWIA has the potential to revolutionise the management of ischaemic left ventricular dysfunction, in a manner analogous to the effect of fractional flow reserve on the management of stable angina.

Abstract
Abstract
Background
Left ventricular thrombus (LVT) complicates around one in six cases of acute and chronic left ventricular systolic dysfunction and is associated with an increased risk of stroke, major systemic embolism and death, believed to be ameliorated by anticoagulation. Off-label use of direct oral anticoagulants (DOACs) for LVT has steadily increased, largely based on favourable outcomes in atrial fibrillation and venous thromboembolism, but the safety and efficacy of DOACs versus vitamin K antagonists (VKA) for LVT remains uncertain.
Purpose
The main aim of our study was to compare treatment of LVT with VKA to DOAC, focusing on all-cause mortality, stroke, major systemic emboli and major bleeding.
Methods
We conducted a retrospective observational longitudinal study of patients presenting to two large quaternary centres between 2011 and 2021 with a diagnosis of LVT. Patients were eligible if they had a documented LVT and received anticoagulation with either VKA or DOAC. Baseline data, thrombus characteristics, treatment type and duration, follow up imaging and clinical events were recorded using electronic health care records. Outcome measures included thrombus resolution, stroke and systemic embolism (SSE), major bleeding and mortality.
Results
A total of 955 patients were identified, of whom 901 received treatment with either a VKA (567 pts, 62.9%) or a DOAC (334 pts, 37.1%) and were included in the analysis. Underlying aetiologies included acute myocardial infarction (AMI) (38.3%), chronic ischaemic cardiomyopathy (38.0%) and non-ischaemic cardiomyopathy (23.7%). Rivaroxaban (43.4%) was the most frequently prescribed DOAC followed by apixaban (35.9%), and the remaining on edoxaban (20.7%). AMI related LVT was more commonly treated with DOAC (53.0%) and chronic ischaemic cardiomyopathy with VKA (72.9%).
There was a lower baseline LVEF in the VKA cohort (29.5±13.2 vs 33.1±14.2, p<0.0001). Other demographic features were comparable. Median follow up was 2.5 years (IQR: 1–3.5). There were no differences in follow up duration between the two treatments (p=0.17). Greater rates of thrombus resolution were seen in the DOAC group compared to VKA (1 year: 78.4% vs 51.4%, p<0.0001), with higher rates of persistent thrombus over the follow-up period seen in the VKA group (25.1% vs 12.9%, p<0.0001). Rates of stroke and systemic embolization were similar between the groups (VKA 9.3% vs 9.6% DOAC, p=0.93). Higher rates of bleeding (BARC >3, 8.1% VKA, 3.6% DOAC, p=0.031) (Figure 1A) and mortality (VKA 18.5%, DOAC 10.2%, p=0.001) (Figure 1B) were seen in the VKA group over the follow-up period.
Conclusions
In a large multi-centre registry of LVT of mixed aetiology, anticoagulation with DOAC was associated with earlier and greater rates of thrombus resolution and consequential reduced adverse events (major bleeding and mortality) during follow up. A funding application to support a multi-centre randomised control trial is underway.

Abstract
BACKGROUND Retention (participants completing a trial) is a persistent, and often under-studied, challenge within clinical trials. Research on retention has focussed on understanding the actions of participants who decide to remain or withdraw from trial participation and developing interventions to target improvements. To better understand how trial staff may influence participants to remain or withdraw from trials, it is important to explore the experiences of staff that recruit and retain said participants and how the process of recruitment impacts retention. METHODS Two qualitative interview studies informed by the Theoretical Domains Framework (TDF) were conducted with staff involved in various stages of clinical trials. The first set of interviews were focussed on staff perceptions about why participants failed to be retained and what helped to keep others engaged in trials, but also explored more generally what strategies or factors contributed to retention in trials. The second set of interviews were focussed on staff perceptions specifically about the recruitment and informed consent process and how that may influence trial retention. All interviews were analysed using the TDF and assigned to relevant behavioural domains according to perceived barriers/facilitators of the target behaviour. Belief statements were generated, summarising the narrative content of related responses within these behavioural domains. These belief statements were further analysed for themes that captured higher order relationships between separate beliefs within and between behavioural domains. RESULTS Twenty-five participants (9 retention staff and 16 recruitment staff) were interviewed. Themes describing the barriers/facilitators to retention broadly, and to communication of retention information at consent, were generated. Four themes on retention broadly and six themes on communication of retention information at consent were identified. Overall, beliefs within all fourteen TDF domains populated these themes. CONCLUSIONS This study explored staff perspectives on retention and how they interpret their behaviour as contributing to retention success. Perspectives varied considerably but several key themes regarding communication were seen consistently. Specific barriers and facilitators within these findings will serve to guide the design of a behavioural intervention aimed at addressing issues within retention. Findings contribute to a notable gap in the literature on staff behaviour in trials and on retention generally.

Abstract
BACKGROUND The benefit of fractional exhaled nitric oxide (FeNO) in guiding asthma treatment is uncertain. We evaluated the efficacy of adding FeNO to symptom-guided treatment in children with asthma versus only symptom-guided treatment. METHODS RAACENO was a multicentre, parallel, randomised, controlled, phase 3 trial done in 35 secondary care centres and 17 primary care recruitment sites (only seven primary care sites managed to recruit patients) in the UK. Patients with a confirmed asthma diagnosis, aged 6-15 years, prescribed inhaled corticosteroids, and who received a course of oral corticosteroids for at least one asthma exacerbation during the 12 months before recruitment were included. Participants were randomly assigned to either FeNO plus symptom-guided treatment (intervention) or symptom-guided treatment alone (standard care) using a 24 h in-house, web-based randomisation system. Participants and the clinical and research teams were not masked to the group allocation. A web-based algorithm gave treatment recommendations based on the Asthma Control Test (ACT) or Childhood ACT (CACT) score; current asthma treatment; adherence to study treatment in the past 3 months; and use of FeNO (in the intervention group). Follow-up occurred at 3-month intervals for 12 months. The primary outcome was any asthma exacerbation treated with oral corticosteroids in the 12 months after randomisation, assessed in the intention-to-treat population. This study is registered with the International Standard Randomised Controlled Trial Registry, ISRCTN67875351. FINDINGS Between June 22, 2017, and Aug 8, 2019, 535 children were assessed for eligibility, 20 were ineligible and six were excluded post-randomisation. 509 children were recruited and at baseline, the mean age of participants was 10·1 years (SD 2·6), and 308 (60·5%) were male. The median FeNO was 21 ppb (IQR 10-48), mean predicted FEV1 was 89·6% (SD 18·0), and median daily dose of inhaled corticosteroids was 400 μg budesonide equivalent (IQR 400-1000). Asthma was partly or fully controlled in 256 (50·3%) of 509 participants. The primary outcome, which was available for 506 (99%) of 509 participants, occurred in 123 (48·2%) of 255 participants in the intervention group and 129 (51·4%) of 251 in the standard care group, the intention-to-treat adjusted odds ratio (OR) was 0·88 (95% CI 0·61 to 1·27; p=0·49). The adjusted difference in the percentage of participants who received the intervention in whom the primary outcome occurred compared with those who received standard care was -3·1% (-11·9% to 5·6%). In 377 (21·3%) of 1771 assessments, the algorithm recommendation was not followed. Adverse events were reported by 27 (5·3%) of 509 participants (15 in the standard care group and 12 in the intervention group). The most common adverse event was itch after skin prick testing (reported by eight participants in each group). INTERPRETATION We found that the addition of FeNO to symptom-guided asthma treatment did not lead to reduced exacerbations among children prone to asthma exacerbation. Asthma symptoms remain the only tool for guiding treatment decisions. FUNDING National Institute for Health Research.

Abstract
OBJECTIVES To identify studies that applied behavioural approaches to issues of recruitment and/or retention to trials; to describe these approaches; and to identify gaps for future research. DESIGN Systematic mapping review of research undertaken in clinical trials within peer-reviewed sources. Review participants were individuals involved in clinical trials, including trial staff, participants, potential participants and former participants. DATA SOURCES MEDLINE, EMBASE, CINAHL, ERIC, PsycINFO, Web of Science and ASSIA from inception to 15 January 2020 with no date or language restrictions. ELIGIBILITY CRITERIA Studies within the context of clinical trials reporting the barriers/facilitators to recruitment and retention, or developing/evaluating solutions to said barriers/facilitators, using a behavioural approach. RESULTS 31 articles were included. Recruitment-focused studies (n=22, 71%) represented the majority. Studies tended to focus on participant behaviours (n=22, 71%). Underserved populations (n=11, 35%) were a notable subset of studies. Most studies (n=23, 74%) were exploratory but those that evaluated interventions (n=8, 26%) often did so within underserved populations (n=6). A majority of studies (n=30, 97%) did not specify their behaviours consistent with guidelines from behavioural scientists. The most used approaches were social cognitive theory (n=8, 26%), the theory of planned behaviour (n=6, 19%) and the theoretical domains framework (n=5, 16%). CONCLUSIONS A range of behavioural approaches have been applied to recruitment and retention to trials. The multitude of recruitment research here is consistent with trials research generally and emphasises the need for research into retention. Authors report target behaviours minimally, which is not conducive to replication. Further research should build on lessons here, such as clearly specifying behaviours. Increased methodological rigour and transparency will lead to robust evidence bases and less research waste in poor recruitment and retention. Overall, trials informed by behavioural approaches promises to be efficient and more participant focused.

Abstract
INTRODUCTION Since its detection in the early 1980s, HIV and AIDS have claimed 32.7 million lives. The HIV epidemic continues to plague the world with its most devastating effects felt in Eastern and Southern Africa. The exposure, vulnerability, and impact of HIV have been prominent among military personnel due to environmental, demographic, and socioeconomic characteristics. Policies have been developed to mitigate its exposure, vulnerability, and impact on the military. However, there are disparities across these policies, especially on recruitment, enlistment, and deployment. These contentions inspired this evaluation, which was designed to provide vital information and insights for militaries developing new HIV policies, for example, the Ghana Armed Forces (GAF). MATERIALS AND METHODS Content analyses of key documents and secondary resources from South Africa (SA), the USA, and the United Nations and International Labour Organizations were undertaken. The key documents evaluated included HIV and AIDS policies of the SA National Defence Force (SANDF), the U.S. DoD, UN Department of Peacekeeping Operations, and International Labour Organization (ILO); national HIV and AIDS policies; and legislations of SA and the USA. RESULTS The SANDF policy permits the recruitment of HIV-positive applicants while the U.S. DoD policy does not. Mandatory pre-employment health assessments including HIV testing is conducted for prospective applicants. Again, discrimination against persons living with HIV (PLHIV) is discouraged by national policies and legislations of both countries and the ILO policy. At the same time, the SA national policy permits discrimination based on requirement of the job.On deployment, the SANDF policy explicitly permits deployment of HIV-positive service members, while the U.S. DoD policy cautiously does so. Both policies support mandatory pre-deployment health assessments in line with the UN peacekeeping policy and medical standards even though voluntary confidential HIV counseling and testing is recommended by the UN. All HIV-positive service members are retained and offered treatment and care services; however, the U.S. DoD policy retires unfit service members after 12 months of consecutive non-deployment. Further, the UN policy repatriates service members with pre-existing medical conditions and pays no compensation for death, injury, or illness, which is due to pre-existing medical conditions or not mission-related. CONCLUSIONS First, the contents of the military policies are not very diverse since most militaries do not enlist or deploy PLHIV except few countries including SA. Implementation and interpretation is however inconsistent. Some militaries continue to exclude PLHIV despite the existence of policies that permit their inclusion. Second, discrepancies exist among the military policies, national legislations, and international policies. The UN policy is not coherent and empowers the military to exclude PLHIV. Also, potential costs to be incurred, in the form of compensation and repatriation, seem to be a major factor in the decision to deploy HIV-positive service members. Harmonization of military HIV policies to ensure uniform standards, interpretation, and implementation and the coherence of the UN policy are essential to guide countries developing new policies, for example, GAF.

Background
Coronary artery bypass grafting (CABG) is an established treatment for patients with advanced coronary artery disease (CAD). A subsequent recurrence of symptoms can cause the need for re-assessment of the coronary circulation. The accuracy of visually assessed stress perfusion cardiovascular magnetic resonance (CMR) for the detection of obstructive CAD is reduced in patients with prior CABG. In patients with complex multi-vessel CAD, myocardial perfusion quantification by CMR is superior to visual assessment (VA) for detection of obstructive disease however patients with CABG have been absent from previous studies.
Purpose
This study sought to assess the performance of myocardial perfusion quantification by CMR against invasive coronary angiography (ICA) for detecting obstructive CAD in patients with previous CABG.
Methods
Twenty-nine patients with a history of previous CABG and subsequent clinically indicated perfusion CMR study and invasive coronary angiography were recruited. Patients underwent a dual bolus stress perfusion CMR with late gadolinium enhancement (LGE) imaging at 3 Tesla. Stress myocardial blood flow (MBF) was estimated at the coronary territory level according to the AHA 16 segment model using Fermi function-constrained deconvolution. Segments with transmural LGE were excluded from MBF analysis. Stress perfusion images were analysed visually alongside LGE images and matched perfusion-LGE defects were considered negative. On ICA, coronary territories with lumen stenosis >70% without an unobstructed bypass graft (<70% stenosis) were considered positive.
Results
86/87 coronary territories were suitable for analysis. Sixty-five territories had at least one bypass graft including 32 territories with arterial grafts. 28/86 territories (33%) had obstructive disease on angiography. Territories with obstructive CAD had significantly lower stress MBF than unobstructed territories (1.21 [IQR: 0.96–1.45] vs 1.58 [1.40–1.84] ml/g/min, p < 0.001, Figure 1). Stress MBF had good accuracy to detect coronary territories with obstructive CAD (sensitivity 71%, specificity 84%, area under the curve (AUC) 0.83, p < 0.001, Figure 2A). For visual assessment, sensitivity was 79%, specificity 78% and diagnostic accuracy 78%. When analysis was confined to only territories with bypass grafts, stress MBF had 78% sensitivity, 81% specificity and AUC of 0.85, p < 0.001 (Figure 2B).. In this subgroup, VA had a sensitivity of 78%, specificity of 76% and a 77% diagnostic accuracy.
Conclusions
In patients with previous surgical revascularisation, quantification of stress myocardial blood flow by CMR offers good diagnostic accuracy for the detection and localisation of anatomically significant stenoses. Accuracy is reduced compared with published data in patients without coronary grafts but remains comparable to expert visual assessment.

Abstract
Background
Ambulance services have a vital role in the shift towards the delivery of health care outside hospitals, when this is better for patients, by offering alternatives to transfer to the emergency department. The introduction of information technology in ambulance services to electronically capture, interpret, store and transfer patient data can support out-of-hospital care.
Objective
We aimed to understand how electronic health records can be most effectively implemented in a pre-hospital context in order to support a safe and effective shift from acute to community-based care, and how their potential benefits can be maximised.
Design and setting
We carried out a study using multiple methods and with four work packages: (1) a rapid literature review; (2) a telephone survey of all 13 freestanding UK ambulance services; (3) detailed case studies examining electronic health record use through qualitative methods and analysis of routine data in four selected sites consisting of UK ambulance services and their associated health economies; and (4) a knowledge-sharing workshop.
Results
We found limited literature on electronic health records. Only half of the UK ambulance services had electronic health records in use at the time of data collection, with considerable variation in hardware and software and some reversion to use of paper records as services transitioned between systems. The case studies found that the ambulance services’ electronic health records were in a state of change. Not all patient contacts resulted in the generation of electronic health records. Ambulance clinicians were dealing with partial or unclear information, which may not fit comfortably with the electronic health records. Ambulance clinicians continued to use indirect data input approaches (such as first writing on a glove) even when using electronic health records. The primary function of electronic health records in all services seemed to be as a store for patient data. There was, as yet, limited evidence of electronic health records’ full potential being realised to transfer information, support decision-making or change patient care.
Limitations
Limitations included the difficulty of obtaining sets of matching routine data for analysis, difficulties of attributing any change in practice to electronic health records within a complex system and the rapidly changing environment, which means that some of our observations may no longer reflect reality.
Conclusions
Realising all the benefits of electronic health records requires engagement with other parts of the local health economy and dealing with variations between providers and the challenges of interoperability. Clinicians and data managers, and those working in different parts of the health economy, are likely to want very different things from a data set and need to be presented with only the information that they need.
Future work
There is scope for future work analysing ambulance service routine data sets, qualitative work to examine transfer of information at the emergency department and patients’ perspectives on record-keeping, and to develop and evaluate feedback to clinicians based on patient records.

Abstract
Background Childhood asthma is a common condition. Currently there is no validated objective test which can be used to guide asthma treatment in children. This study tests the hypothesis that the addition of fractional exhaled nitric oxide (FENO) monitoring in addition to standard care reduces the number of exacerbations (or attacks) in children with asthma. Methods This is a multi-centre, randomised controlled study. Children will be included of age 6–16 years who have a diagnosis of asthma, currently use inhaled corticosteroids (ICSs) and have had an exacerbation in the previous 12 months. Exclusion criteria include being unable to provide FENO measurement at baseline assessment, having another chronic respiratory condition and being currently treated with maintenance oral steroids. Participants will be recruited in both primary and secondary care settings and will be randomised to either receive asthma treatment guided by FENO plus symptoms (FENO group) or asthma treatment guided by symptoms only (standard care group). Within the FENO group, different treatment decisions will be made dependent on changes in FENO. Participants will attend assessments 3, 6, 9 and 12 months post randomisation. The primary outcome is asthma exacerbation requiring prescription and/or use of an oral corticosteroid over 12 months as recorded by the participant/parent or in general practitioner records. Secondary outcomes include time to first attack, number of attacks, asthma control score and quality of life. Adherence to ICS treatment is objectively measured by an electronic logging device. Participants are invited to participate in a “phenotyping” assessment where skin prick reactivity and bronchodilator response are determined and a saliva sample is collected for DNA extraction. Qualitative interviews will be held with participants and research nurses. A health economic evaluation will take place. Discussion This study will evaluate whether FENO can provide an objective index to guide and stratify asthma treatment in children. Trial registration ISRCTN, ISRCTN67875351.

Abstract
PURPOSE The National Cancer Institute has acknowledged that for children, adolescents and young adults (AYAs), cancer is a leading cause of disability and death. This population has unique needs and until we fully understand those needs, we will not be able to provide optimal care. The purpose of this study was to understand the self-reported experience of cancer according to children and AYAs. DESIGN AND METHODS A qualitative descriptive design was used. After obtaining IRB approval, participants were interviewed in Spanish or English. Thirty interviews were conducted with children and AYAs ages 10-22. Questions were asked about the patient's treatment journey and the impact on their lifestyle. The interviews were recorded directly in digital audio files, then transcribed using Verbal Ink®. Themes were derived after the data were organized using Dedoose® and then coded. RESULTS Children and AYAs described the cancer experience as difficult due to activity challenges and disconnection from school. Patients noted that their physical inactivity led to deconditioning. Children and AYAs reported storytelling as a way to cope with newfound disabilities. Patients reported that their illness allowed them to build closer relationships to family. Feelings on other issues arose, such as communication challenges experienced with transition from adult to pediatric hospitals. The value of altruism emerged as a way to provide purpose in their journey. CONCLUSIONS Children and AYAs have particular concerns that the healthcare community needs to address. These qualitative findings have specific recommendations for practice.

Abstract
BackgroundThe roll-out of electronic Patient Clinical Records (ePCR) across UK ambulance services has been an important aspect of modernisation. Electronic Records in Ambulances (ERA) is a two-year study which aims to describe the opportunities and challenges of implementing ePCR and associated technology in emergency ambulances.Our study includes a baseline survey of progress implementing ePCR in all UK ambulance services providing a snapshot of current usage.MethodsWe carried out semi-structured telephone interviews with information managers in each ambulance service in the UK. We asked them about the systems in use, the process and current stage of implementation and explored the perceived value of using ePCR. If services did not use ePCR we asked about plans for future introduction.The interviews were transcribed and thematically analysed, by three members of the research team.ResultsWe completed interviews with 22 managers from 13 services. Implementation varied across the UK. Seven services were using electronic records. Four services had adopted electronic records but, at the time of interview, had reverted to paper with the intention of implementing a new ePCR. Two services still used paper but hoped to move to ePCR in the future. Those who had fully implemented ePCR reported mixed success in terms of staff compliance, and in realising the potential benefits offered by ePCR to link with primary and secondary care.Reported benefits of ePCR were largely associated with improved data management for audit and record keeping. Potential improvements to patient care were discussed, but tended to be associated with future planned developments.ImplicationsImplementation of ePCR has proved challenging with wide variation in use between ambulance services. Progress has been erratic, rather than linear, demonstrated by difficulties that services experienced putting ePCR into practice. There is potential for ambulance services in the earlier stages of implementation to learn from the experiences of others.

Abstract
Although malaria is the world's most life-threatening parasitic disease, there is no clear understanding of how certain biophysical properties of infected cells change during the malaria infection cycle. In this article, we use microfluidic impedance cytometry to measure the dielectric properties of Plasmodium falciparum-infected red blood cells (i-RBCs) at specific time points during the infection cycle. Individual parasites were identified within i-RBCs using green fluorescent protein (GFP) emission. The dielectric properties of cell sub-populations were determined using the multi-shell model. Analysis showed that the membrane capacitance and cytoplasmic conductivity of i-RBCs increased along the infection time course, due to membrane alterations caused by parasite infection. The volume ratio occupied by the parasite was estimated to vary from less than 10% at earlier stages, to approximately 90% at later stages. This knowledge could be used to develop new label-free cell sorting techniques for sample pre-enrichment, improving diagnosis.
