Expedited transfer to a cardiac arrest centre for non-ST-elevation out-of-hospital cardiac arrest (ARREST): a UK prospective, multicentre, parallel, randomised clinical trial.

BACKGROUND: The International Liaison Committee on Resuscitation has called for a randomised trial of delivery to a cardiac arrest centre. We aimed to assess whether expedited delivery to a cardiac arrest centre compared with current standard of care following resuscitated cardiac arrest reduces deaths. METHODS: ARREST is a prospective, parallel, multicentre, open-label, randomised superiority trial. Patients (aged ≥18 years) with return of spontaneous circulation following out-of-hospital cardiac arrest without ST elevation were randomly assigned (1:1) at the scene of their cardiac arrest by London Ambulance Service staff using a secure online randomisation system to expedited delivery to the cardiac catheter laboratory at one of seven cardiac arrest centres or standard of care with delivery to the geographically closest emergency department at one of 32 hospitals in London, UK. Masking of the ambulance staff who delivered the interventions and those reporting treatment outcomes in hospital was not possible. The primary outcome was all-cause mortality at 30 days, analysed in the intention-to-treat (ITT) population excluding those with unknown mortality status. Safety outcomes were analysed in the ITT population. The trial was prospectively registered with the International Standard Randomised Controlled Trials Registry, 96585404. FINDINGS: Between Jan 15, 2018, and Dec 1, 2022, 862 patients were enrolled, of whom 431 (50%) were randomly assigned to a cardiac arrest centre and 431 (50%) to standard care. 20 participants withdrew from the cardiac arrest centre group and 19 from the standard care group, due to lack of consent or unknown mortality status, leaving 411 participants in the cardiac arrest centre group and 412 in the standard care group for the primary analysis. Of 822 participants for whom data were available, 560 (68%) were male and 262 (32%) were female. The primary endpoint of 30-day mortality occurred in 258 (63%) of 411 participants in the cardiac arrest centre group and in 258 (63%) of 412 in the standard care group (unadjusted risk ratio for survival 1·00, 95% CI 0·90-1·11; p=0·96). Eight (2%) of 414 patients in the cardiac arrest centre group and three (1%) of 413 in the standard care group had serious adverse events, none of which were deemed related to the trial intervention. INTERPRETATION: In adult patients without ST elevation, transfer to a cardiac arrest centre following resuscitated cardiac arrest in the community did not reduce deaths.

Understanding the value of a doctorate for allied health professionals in practice in the UK: a survey.

BACKGROUND: The need to transform the United Kingdom's (UK) delivery of health and care services to better meet population needs and expectations is well-established, as is the critical importance of research and innovation to drive those transformations. Allied health professionals (AHPs) represent a significant proportion of the healthcare workforce. Developing and expanding their skills and capabilities is fundamental to delivering new ways of working. However, career opportunities combining research and practice remain limited. This study explored the perceived utility and value of a doctorate to post-doctoral AHPs and how they experience bringing their research-related capabilities into practice environments. METHODS: With a broadly interpretivist design, a qualitatively oriented cross-sectional survey, with closed and open questions, was developed to enable frequency reporting while focusing on the significance and meaning participants attributed to the topic. Participants were recruited via professional networks and communities of practice. Descriptive statistics were used to analyse closed question responses, while combined framework and thematic analysis was applied to open question responses. RESULTS: Responses were received from 71 post-doctoral AHPs located across all four UK nations. Findings are discussed under four primary themes of utilisation of the doctorate; value of the doctorate; impact on career, and impact on self and support. Reference is also made at appropriate points to descriptive statistics summarising closed question responses. CONCLUSION: The findings clearly articulate variability of experiences amongst post-doctoral AHPs. Some were able to influence team and organisational research cultures, support the development of others and drive service improvement. The challenges, barriers and obstacles encountered by others reflect those that have been acknowledged for many years. Acknowledging them is important, but the conversation must move forward and generate positive action to ensure greater consistency in harnessing the benefits and value-added these practitioners bring. If system-wide transformation is the aim, it is inefficient to leave navigating challenges to individual creativity and tenacity or forward-thinking leaders and organisations. There is an urgent need for system-wide responses to more effectively, consistently and equitably enable career pathways combining research and practice for what is a substantial proportion of the UK healthcare workforce.

Nurses' contribution during pandemic conditions: A synthesis of qualitative literature.

OBJECTIVE: To synthesise the evidence relating to the contribution nurses make during respiratory infectious disease pandemics. BACKGROUND: Pandemics are known for their abrupt and contagious nature, as well as their impact on individuals and society. Nurses are more likely to work closely with patients experiencing illness and disease during pandemics, and studies on the role of the profession have mainly focused on the challenges, barriers and shortfalls in nursing care provision. The nursing role in service delivery and their contribution in improving patient well-being has received far less attention. METHODS: In May 2020, three review registers, grey literature and the following databases were searched: Medline via Ovid, Web of Science, CINAHL via EBSCO and Cochrane Library. The specific focus was on qualitative literature that considered the experiences and perceptions of nurses providing care during several respiratory pandemics. Selected papers were appraised using CASP checklist. ENTREQ checklist was used to inform stages associated with the synthesis of selected papers. RESULTS: From 5553 retrieved citations, the analysis of 24 eligible papers resulted in three key themes: the implications of working during pandemics on nurses' personal and family life, nursing contribution in challenging conditions, and working above and beyond. Considering nurses' role in healthcare system, research on their contribution found to have received little appreciation in peer-reviewed journals. CONCLUSIONS: This review pertains to nurses' work in global context and highlights the huge contribution made by the profession in the context of respiratory pandemics. It confirms that nurses' experiences outweighed economic, social and psychological implications of providing care during the pandemic crisis. Acknowledging nurses' resilience and professional motivations, we also argue that the nurse contribution during pandemics can be enhanced when resources, support and training are provided. Further research on contexts and conditions which mitigate nurses the potential for sustained contribution is needed.

Worldwide trends in the burden of asthma symptoms in school-aged children: Global Asthma Network Phase I cross-sectional study.

BACKGROUND: Asthma is the most common chronic disease in children globally. The Global Asthma Network (GAN) Phase I study aimed to determine if the worldwide burden of asthma symptoms is changing. METHODS: This updated cross-sectional study used the same methods as the International study of Asthma and Allergies in Childhood (ISAAC) Phase III. Asthma symptoms were assessed from centres that completed GAN Phase I and ISAAC Phase I (1993-95), ISAAC Phase III (2001-03), or both. We included individuals from two age groups (children aged 6-7 years and adolescents aged 13-14 years) who self-completed written questionnaires at school. We estimated the 10-year rate of change in prevalence of current wheeze, severe asthma symptoms, ever having asthma, exercise wheeze, and night cough (defined by core questions in the questionnaire) for each centre, and we estimated trends across world regions and income levels using mixed-effects linear regression models with region and country income level as confounders. FINDINGS: Overall, 119 795 participants from 27 centres in 14 countries were included: 74 361 adolescents (response rate 90%) and 45 434 children (response rate 79%). About one in ten individuals of both age groups had wheeze in the preceding year, of whom almost half had severe symptoms. Most centres showed a change in prevalence of 2 SE or more between ISAAC Phase III to GAN Phase I. Over the 27-year period (1993-2020), adolescents showed a significant decrease in percentage point prevalence per decade in severe asthma symptoms (-0·37, 95% CI -0·69 to -0·04) and an increase in ever having asthma (1·25, 0·67 to 1·83) and night cough (4·25, 3·06 to 5·44), which was also found in children (3·21, 1·80 to 4·62). The prevalence of current wheeze decreased in low-income countries (-1·37, -2·47 to -0·27], in children and -1·67, -2·70 to -0·64, in adolescents) and increased in lower-middle-income countries (1·99, 0·33 to 3·66, in children and 1·69, 0·13 to 3·25, in adolescents), but it was stable in upper-middle-income and high-income countries. INTERPRETATION: Trends in prevalence and severity of asthma symptoms over the past three decades varied by age group, country income, region, and centre. The high worldwide burden of severe asthma symptoms would be mitigated by enabling access to effective therapies for asthma.

The burden of asthma, hay fever and eczema in adults in 17 countries: GAN Phase I study.

AIMS: Asthma, hay fever and eczema are three common chronic conditions. There have been no recent multi-country data on the burden of these three conditions in adults; the aims of this study are to fill this evidence gap. METHODS: The Global Asthma Network Phase I is a multi-country cross-sectional population-based study using the same core methodology as the International Study of Asthma and Allergies in Childhood Phase III. It provides data on the burden of asthma, hay fever and eczema in children and adolescents, and, for the first time, in their parents/guardians. RESULTS: Data were available from 193 912 adults (104 061 female; mean±sd age 38±7.5 years) in 43 centres in 17 countries. The overall prevalence (range) of symptoms was 6.6% (0.9-32.7%) for current wheeze, 4.4% (0.9-29.0%) for asthma ever, 14.4% (2.8-45.7%) for hay fever ever and 9.9% (1.6-29.5%) for eczema ever. Centre prevalence varied considerably both between countries and within countries. There was a moderate correlation between hay fever ever and asthma ever, and between eczema ever and hay fever ever at the centre level. There were moderate to strong correlations between indicators of the burden of disease reported in adults and the two younger age groups. CONCLUSION: We found evidence for a substantial burden of asthma, hay fever ever and eczema ever in the countries examined, highlighting the major public health importance of these diseases. Prevention strategies and equitable access to effective and affordable treatments for these three conditions would help mitigate the avoidable morbidity they cause.

The burden of asthma, hay fever and eczema in children in 25 countries: GAN Phase I study.

AIMS: There have been no worldwide standardised surveys of prevalence and severity of asthma, rhinoconjunctivitis and eczema in school children for 15 years. The present study aims to provide this information. METHODS: Following the exact International Study of Asthma and Allergies in Childhood (ISAAC) methodology (cross-sectional questionnaire-based survey), Global Asthma Network (GAN) Phase I was carried out between 2015 and 2020 in many centres worldwide. RESULTS: The study included 157 784 adolescents (13-14 years of age) in 63 centres in 25 countries and 101 777 children (6-7 years of age) in 44 centres in 16 countries. The current prevalence of symptoms, respectively, was 11.0% and 9.1% for asthma, 13.3% and 7.7% for rhinoconjunctivitis and 6.4% and 5.9% for eczema. The prevalence of asthma ever was 10.5% and 7.6%, hay fever ever was 15.2% and 11.1% and eczema ever was 10.6% and 13.4%, respectively. Centres in low or lower middle gross national income countries (LICs or LMICs) had significantly lower prevalence of the three disease symptoms and diagnoses (except for hay fever). In children, the prevalence of asthma and rhinoconjunctivitis symptoms was higher in boys, while the reverse occurred among adolescents. For eczema, while the prevalence among female adolescents was double that of males, there was no sex difference among children. Centre accounted for non-negligible variability in all disease symptoms (10-20%). CONCLUSION: The burdens of asthma, rhinoconjunctivitis and eczema vary widely among the limited number of countries studied. Although symptom prevalence is lower in LICs and LMICs, it represents a considerable burden everywhere studied.

Worldwide time trends in prevalence of symptoms of rhinoconjunctivitis in children: Global Asthma Network Phase I.

BACKGROUND: The Global Asthma Network (GAN), by using the International Study of Asthma and Allergies in Childhood (ISAAC) methodology, has updated trends in prevalence of symptoms of childhood allergic diseases, including non-infective rhinitis and conjunctivitis ('rhinoconjunctivitis'), which is reported here. METHODS: Prevalence and severity of rhinoconjunctivitis were assessed by questionnaire among schoolchildren in GAN Phase I and ISAAC Phase I and III surveys 15-23 years apart. Absolute rates of change in prevalence were estimated for each centre and modelled by multi-level linear regression to compare trends by age group, time period and per capita national income. RESULTS: Twenty-seven GAN centres in 14 countries surveyed 74,361 13- to 14-year-olds ('adolescents') and 45,434 6- to 7-year-olds ('children'), with average response proportions of 90% and 79%, respectively. Many centres showed highly significant (p < .001) changes in prevalence of rhinoconjunctivitis in the past year ('current rhinoconjunctivitis') compared with ISAAC. The direction and magnitude of centre-level trends varied significantly (p < .001) both within and between countries. Overall, current rhinoconjunctivitis prevalence decreased slightly from ISAAC Phase III to GAN: -1.32% per 10 years, 95% CI [-2.93%, +0.30%] among adolescents; and -0.44% [-1.29%, +0.42%] among children. Together, these differed significantly (p < .001) from the upward trend within ISAAC. Among adolescents, centre-level trends in current rhinoconjunctivitis were highly correlated with those for eczema symptoms (rho = 0.72, p < .0001) but not with centre-level trends in asthma symptoms (rho = 0.15, p = .48). Among children, these correlations were positive but not significant. CONCLUSION: Symptoms of non-infective rhinoconjunctivitis among schoolchildren may no longer be on the increase globally, although trends vary substantially within and between countries.

Determinants of nurse job dissatisfaction - findings from a cross-sectional survey analysis in the UK.

BACKGROUND: A lower recruitment and high turnover rate of registered nurses have resulted in a global shortage of nurses. In the UK, prior to the COVID-19 epidemic, nurses' intention to leave rates were between 30 and 50% suggesting a high level of job dissatisfaction. METHODS: In this study, we analysed data from a cross-sectional mixed-methods survey developed by the Royal College of Nursing and administered to the nursing workforce across all four UK nations, to explore the levels of dissatisfaction and demoralisation- one of the predictors of nurses' intention to leave. We carried out logistic regression analysis on available data in order to determine what impacts job dissatisfaction. RESULTS: In total, 1742 nurses responded to questions about working conditions on their last shift. We found that nearly two-thirds of respondents were demoralised. Nurses were five times more likely (OR 5.08, 95% CI: 3.82-6.60) to feel demoralised if they reported missed care. A perceived lack of support had nearly the same impact on the level of demoralisation (OR 4.8, 95% CI: 3.67-6.38). These findings were reflected in the qualitative findings where RNs reported how staffing issues and failures in leadership, left them feeling disempowered and demoralised. CONCLUSION: A large proportion of nurses reported feeling dissatisfied and demoralised. In order to reduce the negative impact of dissatisfaction and improve retention, more research needs to investigate the relationship dynamics within healthcare teams and how the burden experienced by RNs when unsupported by managers impacts on their ability to provide safe, good-quality care. These findings predate the current Covid-19 pandemic outbreak which may have had a further detrimental effect on job satisfaction in the UK and other nation's nursing workforce.

Early remote ischaemic preconditioning leads to sustained improvement in allograft function after live donor kidney transplantation: long-term outcomes in the REnal Protection Against Ischaemia-Reperfusion in transplantation (REPAIR) randomised trial.

BACKGROUND: The REnal Protection Against Ischaemia-Reperfusion in transplantation (REPAIR) RCT examined whether remote ischaemic preconditioning (RIPC) improved renal function after living-donor kidney transplantation. The primary endpoint, glomerular filtration rate (GFR), quantified by iohexol at 12 months, suggested that RIPC may confer longer-term benefit. Here, we present yearly follow-up data of estimated GFR for up to 5 yr after transplantation. METHODS: In this double-blind, factorial RCT, we enrolled 406 adult live donor kidney transplant donor-recipient pairs in 15 European transplant centres. RIPC was performed before induction of anaesthesia. RIPC consisted of four 5 min inflations of a BP cuff on the upper arm to 40 mm Hg above systolic BP separated by 5 min periods of cuff deflation. For sham RIPC, cuff inflation to 40 mm Hg was undertaken. Pairs were randomised to sham RIPC, early RIPC only (immediately pre-surgery), late RIPC only (24 h pre-surgery), or dual RIPC (early and late RIPC). The pre-specified secondary outcome of estimated GFR (eGFR) was calculated from serum creatinine measurements, using the Chronic Kidney Disease Epidemiology Collaboration equation. Predefined safety outcomes were mortality and graft loss. RESULTS: There was a sustained improvement in eGFR after early RIPC, compared with control from 3 months to 5 yr (adjusted mean difference: 4.71 ml min-1 (1.73 m)-2 [95% confidence interval, CI: 1.54-7.89]; P=0.004). Mortality and graft loss were similar between groups (RIPC: 20/205 [9.8%] vs control 24/201 [11.9%]; hazard ratio: 0.79 [95% CI: 0.43-1.43]). CONCLUSIONS: RIPC safely improves long-term kidney function after living-donor renal transplantation when administered before induction of anaesthesia. CLINICAL TRIAL REGISTRATION: ISRCTN30083294.

Remote Ischemic Preconditioning and Outcomes of Cardiac Surgery.

BACKGROUND: Whether remote ischemic preconditioning (transient ischemia and reperfusion of the arm) can improve clinical outcomes in patients undergoing coronary-artery bypass graft (CABG) surgery is not known. We investigated this question in a randomized trial. METHODS: We conducted a multicenter, sham-controlled trial involving adults at increased surgical risk who were undergoing on-pump CABG (with or without valve surgery) with blood cardioplegia. After anesthesia induction and before surgical incision, patients were randomly assigned to remote ischemic preconditioning (four 5-minute inflations and deflations of a standard blood-pressure cuff on the upper arm) or sham conditioning (control group). Anesthetic management and perioperative care were not standardized. The combined primary end point was death from cardiovascular causes, nonfatal myocardial infarction, coronary revascularization, or stroke, assessed 12 months after randomization. RESULTS: We enrolled a total of 1612 patients (811 in the control group and 801 in the ischemic-preconditioning group) at 30 cardiac surgery centers in the United Kingdom. There was no significant difference in the cumulative incidence of the primary end point at 12 months between the patients in the remote ischemic preconditioning group and those in the control group (212 patients [26.5%] and 225 patients [27.7%], respectively; hazard ratio with ischemic preconditioning, 0.95; 95% confidence interval, 0.79 to 1.15; P=0.58). Furthermore, there were no significant between-group differences in either adverse events or the secondary end points of perioperative myocardial injury (assessed on the basis of the area under the curve for the high-sensitivity assay of serum troponin T at 72 hours), inotrope score (calculated from the maximum dose of the individual inotropic agents administered in the first 3 days after surgery), acute kidney injury, duration of stay in the intensive care unit and hospital, distance on the 6-minute walk test, and quality of life. CONCLUSIONS: Remote ischemic preconditioning did not improve clinical outcomes in patients undergoing elective on-pump CABG with or without valve surgery.

Gender relations and couple negotiations of British men's food practice changes after prostate cancer.

Nutrition plays an important role in the health of men diagnosed with prostate cancer and dietary interventions can therefore be a significant part of prostate cancer survivorship supportive care. Family food provision, however, involves complex social interactions, which shape how men engage with their diets and dietary interventions. The role that gender plays in shaping prostate cancer couples' food practices and men's diets after a prostate cancer diagnosis is thought to be important but is little understood. This study explored couples' accounts of nutrition information seeking and diet change to gain a better understanding of how gender relations shaped men's food practices after prostate cancer diagnosis. Qualitative health interviews with men and their partners were conducted and analysed using interpretive descriptive methods. Findings demonstrated how couples navigated food change journeys that involved seeking information, deciding what changes were warranted and implementing and regulating diet changes. Two overarching themes that illustrated couples' food negotiations were called 'Seeking information and deciding on food changes' and 'Monitoring food changes'. Additional sub-themes described who led food changes, women's filtering of information, and moderation or 'treats'. Throughout these food change journeys, interactions between men and women were at play, demonstrating how gender relations and dynamics acted to shape couples' food negotiations and men's food practices. Findings reveal that attention to gender relations and the men's family food dynamics should inform diet interventions for men with prostate cancer in order to improve uptake.

Attentional dynamics of infant visual foraging.

Young infants actively gather information about their world through visual foraging, but the dynamics of this important behavior is poorly understood, partly because developmental scientists have often equated its essential components, looking and attending. Here we describe a method for simultaneously tracking spatial attention to fixated and nonfixated locations during free looking in 12-week-old infants using steady-state visual evoked potentials (SSVEPs). Using this method, we found that the sequence of locations an infant inspects during free looking reflects a momentary bias away from locations that were recently the target of covert attention, quickly followed by the redirection of attention--in advance of gaze--to the next target of fixation. The result is a pattern of visual foraging that is likely to support efficient exploration of complex environments by facilitating the inspection of new locations in real time.

Health improvement for men and hard-to-engage-men delivered in English Premier League football clubs.

Unhealthy behaviours represent modifiable causes of non-communicable disease. In men, concern focuses on those (i) demonstrating the poorest health, exacerbated by a lack of awareness of the risks that their lifestyles pose and (ii) who neither consult their doctor nor use health services. Classed as 'hard-to-engage', distinctive strategies are needed to reach these men. Impact and process evaluations assessed the effect of a programme of men's health-delivered in/by English Premier League football clubs. Men attended match-day events and/or weekly classes involving physical activity and health education. Validated self-report measures for demographics and lifestyle behaviours were completed pre- and post-intervention. Intention-to-treat analysis was performed on pre-versus-post-intervention differences in lifestyle profiles, whereas interviews (n = 57) provided men's accounts of programme experience. Participants were predominantly white British (70.4%/n = 2669), 18-44 (80.2%/n = 3032) and employed (60.7%/n = 1907). One-third (n = 860) 'never' visited their doctor. Over 85% (n = 1428) presented with combinations of lifestyle risk factors. Intention-to-treat analysis showed improvements (P < 0.001) in lifestyle profiles. Interviews confirmed recruitment of men who were hard-to-engage and unhealthy. Men were attracted through football and/or the clubs, whereas specific design factors impacted on participation. Limitations include use of self-reports, narrow demographics, small effect sizes, lack of follow-up and the absence of non-completers in interviews.

Empty-headed dynamical model of infant visual foraging.

Visual foraging is one important way that very young infants explore and learn about their environment. We recently showed that a simple stochastic dynamical model acts quantitatively like free-looking 1-month-old infants, even though it does not include any components that directly represent the perceptual-cognitive processes that operate on the input from visual foraging. This suggested that early in development, generic low-level processes like noise and hysteresis in the mechanisms controlling gaze may drive visual foraging behavior and therefore regulate the input to higher-level perceptual-cognitive processes that later come to have more influence on free looking. Here we evaluate the model's ability to behave like 3-month-olds studied under the same experimental conditions as 1-month-olds. The results show that the empty-headed model can also behave like 3-month-old infants, although not as well as 1-month-olds. Its partial success at 3 months suggests that generic low-level processes controlling gaze remain important in visual foraging. Its pattern of failure suggests that by 3 months time-dependent processes like attention have become especially important.

Quantifying potential fluid transfused through pressure monitoring and circuit flushes in pediatric ECMO patients.

Pressure monitoring on pediatric Extracorporeal Membrane Oxygenation (ECMO) circuits is used to aid in the evaluation of patient hemodynamics and circuit health. Extracorporeal Life Support Organization (ELSO) recommends monitoring pressures on the venous line, pre-, and post-oxygenator. In order to keep pressure ports patent, crystalloid can be used as a flush. The fluid transfused to the patient through these lines can be challenging to quantify accurately due to variance in clinician practice. Currently, there is no published data or practice suggestions on this topic. In Vitro experiments using Edwards True Wave transducers and pressure bags were constructed, allowing for common negative and positive pressures to be simulated. Passive volume infused through the transducer as well as intermittent active flushing by pulling the snap tab were measured and the volumes were recorded. When the pressure transducer and associated tubing are kept patent by using a pressurized IV bag, per the instructions for use, the daily volume transfused was found to be 319.6 mL or close to a typical neonate's total blood volume. Rather than using passive or active flushing, the use of automated syringe pumps can reduce the transfused volume to 24 mL per day. Further study is recommended to develop and publish best practices.

Comparison between propofol and total inhalational anaesthesia on cardiovascular outcomes following on-pump cardiac surgery in higher-risk patients: a randomised controlled pilot and feasibility study.

OBJECTIVES: Myocardial revascularisation and cardiopulmonary bypass (CPB) can cause ischaemia-reperfusion injury, leading to myocardial and other end-organ damage. Volatile anaesthetics protect the myocardium in experimental studies. However, there is uncertainty about whether this translates into clinical benefits because of the coadministration of propofol and its detrimental effects, restricting myocardial protective processes. METHODS: In this single-blinded, parallel-group randomised controlled feasibility trial, higher-risk patients undergoing elective coronary artery bypass graft (CABG) surgery with an additive European System for Cardiac Operative Risk Evaluation ≥5 were randomised to receive either propofol or total inhalational anaesthesia as single agents for maintenance of anaesthesia. The primary outcome was the feasibility of recruiting and randomising 50 patients across two cardiac surgical centres, and secondary outcomes included the feasibility of collecting the planned perioperative data, clinically relevant outcomes and assessments of effective patient identification, screening and recruitment. RESULTS: All 50 patients were recruited within 11 months in two centres, allowing for a 13-month hiatus in recruitment due to the COVID-19 pandemic. Overall, 50/108 (46%) of eligible patients were recruited. One patient withdrew before surgery and one patient did not undergo surgery. All but one completed in-hospital and 30-day follow-up. CONCLUSIONS: It is feasible to recruit and randomise higher-risk patients undergoing CABG surgery to a study comparing total inhalational and propofol anaesthesia in a timely manner and with high acceptance and completion rates. TRIAL REGISTRATION NUMBER: NCT04039854.

Optimizing lifestyles for men regarded as 'hard-to-reach' through top-flight football/soccer clubs.

This study assessed the effect of a 12-week behavioural intervention delivered in and by English Premier League football/soccer clubs, and its influence on lifestyle behaviours, in men typically regarded as hard-to-reach. One hundred and thirty men aged 18 years or older engaging in the programme self-reported data on optimal lifestyle behaviours (OLBs) (physical activity, diet, smoking and alcohol consumption) at pre- and post-intervention. Logistic regression models were used to predict the likelihood of OLBs post-intervention. Healthy behaviours were uncommon at baseline, yet at 12 weeks, 19% (n = 24) of men displayed positive change in one behaviour and 67% (n = 87) had changed ≥2. A combination of improving diet (odds ratio [OR] = 2.76; 95% confidence interval [CI] = 1.65-4.63) and being employed (OR = 4.90, CI = 1.46-16.5) significantly increased the likelihood of reporting ≥150 min of physical activity per week. Increased physical activity significantly increased the likelihood of self-reporting a healthy diet (OR = 2.32, CI = 1.36-3.95). This study shows that a 12-week behavioural intervention can reach and engage a proportion of at risk men. Further, among such men, the intervention helped to stabilize and improve several of the most important lifestyle behaviours that impact mortality and morbidity.

Exposure assessment for repeated sub-concussive head impacts in soccer: The HEalth and Ageing Data IN the Game of football (HEADING) study.

The purpose of this paper was to develop exposure estimates for repetitive sub-concussive head impacts (RSHI) for use in epidemiological analyses. We used a questionnaire to collect lifetime history of heading and other head contacts associated with training and playing football from 159 former footballers all members of the English professional football association. We used linear mixed effect regression with player as the random effect, to model the number of headers, blows to the head and head-to-head impacts as a function of potential exposure affecting factors, which were treated as the fixed effects. Exposure affecting factors included playing position, league, context of play (game vs training) and decade of play. Age at time of response to the questionnaire was also included in the models. In model results, playing position was important, with RSHIs being highest among defenders and lowest among goalkeepers. Players headed the ball more during games than in training, and when playing in amateur or youth leagues compared with semi-professional or professional leagues. The average number of reported head impacts declined linearly throughout the observation period (1949-2015). The derived final model for headers explained 43%, 9% and 36% of the between player, within player and total variance in exposure, respectively with good precision and predictive performance. These findings are generally in agreement with previously published results pointing towards the models forming a valid method for estimating exposure to RSHI among former footballers although some further external validation is still warranted.

Training and development experiences of nursing associate trainees based in primary care across England: a qualitative study.

BACKGROUND: The nursing associate role was first deployed in England in 2019 to fill a perceived skills gap in the nursing workforce between healthcare assistants and registered nurses and to offer an alternative route into registered nursing. Initially, trainee nursing associates were predominantly based in hospital settings; however, more recently, there has been an increase in trainees based in primary care settings. Early research has focussed on experiences of the role across a range of settings, particularly secondary care; therefore, little is known about the experiences and unique support needs of trainees based in primary care. AIM: To explore the experiences and career development opportunities for trainee nursing associates based in primary care. METHODS: This study used a qualitative exploratory design. Semi-structured interviews were undertaken with 11 trainee nursing associates based in primary care from across England. Data were collected between October and November 2021, transcribed and analysed thematically. FINDINGS: Four key themes relating to primary care trainee experiences of training and development were identified. Firstly, nursing associate training provided a 'valuable opportunity for career progression'. Trainees were frustrated by the 'emphasis on secondary care' in both academic content and placement portfolio requirements. They also experienced 'inconsistency in support' from their managers and assessors and noted a number of 'constraints to their learning opportunities', including the opportunity to progress to become registered nurses. CONCLUSION: This study raises important issues for trainee nursing associates, which may influence the recruitment and retention of the nursing associate workforce in primary care. Educators should consider adjustments to how the curriculum is delivered, including primary care skills and relevant assessments. Employers need to recognise the resource requirements for the programme, in relation to time and support, to avoid undue stress for trainees. Protected learning time should enable trainees to meet the required proficiencies.

Asthma inflammatory phenotypes on four continents: most asthma is non-eosinophilic.

BACKGROUND: Most studies assessing pathophysiological heterogeneity in asthma have been conducted in high-income countries (HICs), with little known about the prevalence and characteristics of different asthma inflammatory phenotypes in low-and middle-income countries (LMICs). This study assessed sputum inflammatory phenotypes in five centres, in Brazil, Ecuador, Uganda, New Zealand (NZ) and the United Kingdom (UK). METHODS: We conducted a cross-sectional study of 998 asthmatics and 356 non-asthmatics in 2016-20. All centres studied children and adolescents (age range 8-20 years), except the UK centre which involved 26-27 year-olds. Information was collected using questionnaires, clinical characterization, blood and induced sputum. RESULTS: Of 623 asthmatics with sputum results, 39% (243) were classified as eosinophilic or mixed granulocytic, i.e. eosinophilic asthma (EA). Adjusted for age and sex, with NZ as baseline, the UK showed similar odds of EA (odds ratio 1.04, 95% confidence interval 0.37-2.94) with lower odds in the LMICs: Brazil (0.73, 0.42-1.27), Ecuador (0.40, 0.24-0.66) and Uganda (0.62, 0.37-1.04). Despite the low prevalence of neutrophilic asthma in most centres, sputum neutrophilia was increased in asthmatics and non-asthmatics in Uganda. CONCLUSIONS: This is the first time that sputum induction has been used to compare asthma inflammatory phenotypes in HICs and LMICs. Most cases were non-eosinophilic, including in settings where corticosteroid use was low. A lower prevalence of EA was observed in the LMICs than in the HICs. This has major implications for asthma prevention and management, and suggests that novel prevention strategies and therapies specifically targeting non-eosinophilic asthma are required globally.
