Abstract
OBJECTIVES Attenuated symptoms of psychosis are a core feature of At-Risk Mental States. However, subthreshold levels of paranoia are also common among nonpsychosis populations. At present, little is known about whether the processes underpinning the experience of paranoid ideation in high-risk youth differ as a consequence of meeting At-Risk Mental States (ARMS) for psychosis criteria. METHODS This study utilized path analysis techniques to examine the relationships between schematic beliefs, negative affect and the experience of paranoia for two groups: a group meeting criteria for ARMS (n = 133) and a group presenting with emerging complex mental health difficulties who did not meet the criteria for ARMS (n = 137). RESULTS While the ARMS group displayed significantly greater maladaptive schematic beliefs and more severe symptomatology, the associations between schematic beliefs, symptoms of negative affect and paranoia did not differ as a consequence of ARMS status. CONCLUSIONS While meeting the ARMS criteria is associated with experiencing more maladaptive cognitions and more negative symptomatology among at-risk youth, the associations between these cognitive beliefs and symptoms may be similar for youth who do not meet ARMS. These findings have implications for broadening the scope of at-risk/high-risk and for developing effective interventions for young people presenting with emerging difficulties.

Abstract
Introduction Recognition of the essential role of nature-based activities for general wellbeing is expanding. Currently, there is limited evidence of the benefits of green care for those with severe and enduring mental illness, including psychosis. Objectives We aim to establish benefits and difficulties encountered during a 10-session green care programme for 18-30 year olds who have experienced first episode of psychosis (FEP) using a mixed methods approach. Methods This was a service evaluation of a ’Woodland Group’ of 10 half-day sessions for participants with FEP. Sessions consisted of a welcome and agenda setting, ice-breaking activity, core nature-based activity. Quantitative data for this evaluation was collected through the 15-item Questionnaire on the Process of Recovery (QPR), and a semi-structured intervention experience questionnaire. Qualitative data was collected via a focus group. Thematic analysis was performed by the three co-authors. Results 4/8 patients showed reliable improvement on QPR outcome measures, 1 showed deterioration and 3 showed no change. Mean QPR scores showed modest increase from average 3.4 (week 1) to 3.8 (week 10). 100% of respondents would recommend this group to others. Thematic analysis identified themes of connection with nature and others, development of a sense of wellbeing and ‘peacefulness’ and new perspectives on psychotic experience. Conclusions This small, retrospective evaluation is the first to investigate green care interventions for young people experiencing FEP. Our results reflect the positive informal feedback from participants and supporting staff. Limitations include small sample size, incomplete data, and reliance on patient-reported outcomes. These findings show promise for nature-based activities within EIS. Disclosure No significant relationships.

Abstract
BACKGROUND Suicidal ideation is an increasingly common presentation to the paediatric emergency department. The presence of suicidal ideation is linked to acute psychiatric hospital admission and increased risk of suicide. The paediatric emergency department plays a critical role in reducing risk of suicide, strengthening protective factors and encouraging patient engagement with ongoing care. AIMS This rapid review aims to synthesise evidence on interventions that can be implemented in the paediatric emergency department for children and adolescents presenting with suicidal ideation. METHOD Six electronic databases were searched for studies published since January 2010: PubMed, Web of Science, Medline, PsycINFO, CINAHL and Cochrane. Outcomes of interest included suicidal ideation, engagement with out-patient services, incidence of depressive symptoms, hopelessness, family empowerment, hospital admission and feasibility of interventions. The Cochrane risk-of-bias tool was used to evaluate the quality of studies. RESULTS Six studies of paediatric emergency department-initiated family-based (n = 4) and motivational interviewing interventions (n = 2) were narratively reviewed. The studies were mainly small and of varying quality. The evidence synthesis suggests that both types of intervention, when initiated by the paediatric emergency department, reduce suicidal ideation and improve patient engagement with out-patient services. Family-based interventions also showed a reduction in suicidality and improvement in family empowerment, hopelessness and depressive symptoms. CONCLUSIONS Paediatric emergency department-initiated interventions are crucial to reduce suicidal ideation and risk of suicide, and to enhance ongoing engagement with out-patient services. Further research is needed; however, family-based and motivational interviewing interventions could be feasibly and effectively implemented in the paediatric emergency department setting.

Abstract
BACKGROUND Young people with social disability and severe and complex mental health problems have poor outcomes, frequently struggling with treatment access and engagement. Outcomes may be improved by enhancing care and providing targeted psychological or psychosocial intervention. AIMS We aimed to test the hypothesis that adding social recovery therapy (SRT) to enhanced standard care (ESC) would improve social recovery compared with ESC alone. METHOD A pragmatic, assessor-masked, randomised controlled trial (PRODIGY: ISRCTN47998710) was conducted in three UK centres. Participants (n = 270) were aged 16-25 years, with persistent social disability, defined as under 30 hours of structured activity per week, social impairment for at least 6 months and severe and complex mental health problems. Participants were randomised to ESC alone or SRT plus ESC. SRT was an individual psychosocial therapy delivered over 9 months. The primary outcome was time spent in structured activity 15 months post-randomisation. RESULTS We randomised 132 participants to SRT plus ESC and 138 to ESC alone. Mean weekly hours in structured activity at 15 months increased by 11.1 h for SRT plus ESC (mean 22.4, s.d. = 21.4) and 16.6 h for ESC alone (mean 27.7, s.d. = 26.5). There was no significant difference between arms; treatment effect was -4.44 (95% CI -10.19 to 1.31, P = 0.13). Missingness was consistently greater in the ESC alone arm. CONCLUSIONS We found no evidence for the superiority of SRT as an adjunct to ESC. Participants in both arms made large, clinically significant improvements on all outcomes. When providing comprehensive evidence-based standard care, there are no additional gains by providing specialised SRT. Optimising standard care to ensure targeted delivery of existing interventions may further improve outcomes.

Abstract
BACKGROUND Young people with social disability and non-psychotic severe and complex mental health problems are an important group. Without intervention, their social problems can persist and have large economic and personal costs. Thus, more effective evidence-based interventions are needed. Social recovery therapy is an individual therapy incorporating cognitive-behavioural techniques to increase structured activity as guided by the participant's goals. OBJECTIVE This trial aimed to test whether or not social recovery therapy provided as an adjunct to enhanced standard care over 9 months is superior to enhanced standard care alone. Enhanced standard care aimed to provide an optimal combination of existing evidence-based interventions. DESIGN A pragmatic, single-blind, superiority randomised controlled trial was conducted in three UK centres: Sussex, Manchester and East Anglia. Participants were aged 16-25 years with persistent social disability, defined as < 30 hours per week of structured activity with social impairment for at least 6 months. Additionally, participants had severe and complex mental health problems, defined as at-risk mental states for psychosis or non-psychotic severe and complex mental health problems indicated by a Global Assessment of Functioning score ≤ 50 persisting for ≥ 6 months. Two hundred and seventy participants were randomised 1 : 1 to either enhanced standard care plus social recovery therapy or enhanced standard care alone. The primary outcome was weekly hours spent in structured activity at 15 months post randomisation. Secondary outcomes included subthreshold psychotic, negative and mood symptoms. Outcomes were collected at 9 and 15 months post randomisation, with maintenance assessed at 24 months. RESULTS The addition of social recovery therapy did not significantly increase weekly hours in structured activity at 15 months (primary outcome treatment effect -4.44, 95% confidence interval -10.19 to 1.31). We found no evidence of significant differences between conditions in secondary outcomes at 15 months: Social Anxiety Interaction Scale treatment effect -0.45, 95% confidence interval -4.84 to 3.95; Beck Depression Inventory-II treatment effect -0.32, 95% confidence interval -4.06 to 3.42; Comprehensive Assessment of At-Risk Mental States symptom severity 0.29, 95% confidence interval -4.35 to 4.94; or distress treatment effect 4.09, 95% confidence interval -3.52 to 11.70. Greater Comprehensive Assessment of At-Risk Mental States for psychosis scores reflect greater symptom severity. We found no evidence of significant differences at 9 or 24 months. Social recovery therapy was not estimated to be cost-effective. The key limitation was that missingness of data was consistently greater in the enhanced standard care-alone arm (9% primary outcome and 15% secondary outcome missingness of data) than in the social recovery therapy plus enhanced standard care arm (4% primary outcome and 9% secondary outcome missingness of data) at 15 months. CONCLUSIONS We found no evidence for the clinical superiority or cost-effectiveness of social recovery therapy as an adjunct to enhanced standard care. Both arms made large improvements in primary and secondary outcomes. Enhanced standard care included a comprehensive combination of evidence-based pharmacological, psychotherapeutic and psychosocial interventions. Some results favoured enhanced standard care but the majority were not statistically significant. Future work should identify factors associated with the optimal delivery of the combinations of interventions that underpin better outcomes in this often-neglected clinical group.

Abstract
Abstract
Introduction
Ischaemic heart disease (IHD) remains the leading cause of mortality globally1. The presence and extent of coronary artery calcification (CAC) is a strong predictor of cardiovascular events, and CAC scoring has been shown to be more predictive of cardiovascular events than other traditional risk assessment scores2.
Incidental coronary calcification can be detected and quantified on non-gated CT chest scans covering the heart in the field of view3. This finding is typically not reported4 and hence an opportunity to optimise cardiovascular risk assessment and treatment is missed.
Purpose
We sought to investigate whether patients presenting to our centre with an acute coronary syndrome (ACS) event had historical CT imaging demonstrating coronary artery calcification.
Methods
We retrospectively reviewed case records for all patients referred to our centre for an invasive coronary angiogram following their first known admission with an ACS event. ACS were defined according to contemporary guidelines from the European Society of Cardiology. We reviewed a 3 month period prior to the COVID-19 pandemic (01/01/2019–31/03/2019). The national imaging database was interrogated to identify previous CT imaging that includes the heart in the field of view. The presence of coronary calcification was confirmed and quantified using an ordinal scoring method previously described3. The clinical radiology reports for the scans were reviewed to determine the frequency of CAC being reported.
Demographic information was collected from our electronic patient record including the presence of risk factors for IHD. Prescribed medication prior to admission was also recorded using the on-admission medicines reconciliation documented in the electronic patient record.
Results
385 patients with first presentation of ACS were identified. 75 (19%) had a prior non-gated CT chest imaging. The most common indication for CT was for investigation of possible malignancy. The mean interval from CT imaging to ACS admission was 36 months.
CAC was present on 67 (89%) scans. The mean ordinal score was 4.04, corresponding to moderate CAC. The distribution of CAC by coronary artery revealed the majority of disease to involve the left anterior descending artery (Table 1). Only 12/67 (18%) of clinical radiology reports mentioned coronary calcification (Figure 1).
Patients with CAC frequently had additional risk factors for IHD. Despite this only 42% were prescribed antiplatelet therapy, and only 45% prescribed a statin.
Conclusions
A significant proportion of ACS admissions have evidence of CAC on historical CT scans. This finding is often not reported and the majority of patients with demonstrated coronary artery disease are not prescribed appropriate preventative therapies. Systematic reporting of this finding may have a significant impact on the prevention of acute cardiovascular events.

Abstract
Abstract
Background
Microvascular obstruction affects half of patients with ST-segment elevation myocardial infarction (STEMI) and confers an adverse prognosis. Feature-tracking (FT) cardiac magnetic resonance (CMR) allows myocardial strain assessment from standard cine images without the need for specialist sequences. Myocardial strain reflects both systolic and diastolic function allowing the assessment of both global and regional myocardial deformation. Strain recovery is impaired in patients with microvascular obstruction. There is growing evidence to suggest that global circumferential strain may offer incremental value beyond traditional CMR endpoints.
Purpose
We aimed to determine whether a therapeutic strategy involving low-dose intracoronary alteplase improves global circumferential strain in STEMI.
Methods
Between March 17, 2016, and December 21, 2017, 440 patients presenting at 11 hospitals in the United Kingdom within 6 hours of STEMI were randomised in a 1:1:1 dose-ranging trial design. Participants were randomly assigned to treatment with placebo (n=151), alteplase 10mg (n=144), or alteplase 20mg (n=145). The primary outcome was the amount of microvascular obstruction (%left ventricular mass) quantified by CMR at 2–7 days. Global circumferential strain was a prespecified secondary endpoint measured at 2–7 days and 3 months. Troponin T AUC was measured at 0, 2, and 24 hours post reperfusion. Patients were followed up to 1 year with all events adjudicated by an independent committee.
Results
Among the 440 patients who were randomised (mean age 60.5 years; 85% male), the primary endpoint was achieved in 396 (90%), all patients were followed up to 1 year for clinical events. The amount (mean, standard deviation) of microvascular obstruction was not different between the groups (2.3% vs. 2.6% vs. 3.5% left ventricular mass); p=0.28. Global circumferential strain was worse in patients receiving alteplase. −23.1% (placebo) vs −20.6 (10mg alteplase) vs −22.0% (20mg alteplase); mean difference for both doses combined vs placebo: 1.8% (95% CI 0.5, 3.2), p=0.009. There were no differences between groups in the other CMR endpoints including LV ejection fraction (LVEF). The area-under-the-curve for troponin T measured in 317 (72%) patients was increased in both treatment groups compared to placebo, mean difference 1.53 (95% CI: 1.16, 2.01), p=0.002. There were no differences in MACE at 1 year; placebo n=16 (10.6%), 10mg alteplase n=22 (15.3%), 20mg alteplase group n=15 (10.3%).
Conclusion
In patients presenting within 6 hours of STEMI, low-dose intracoronary alteplase compared with placebo did not reduce microvascular obstruction. There was a reduction in global circumferential strain and an increase in Troponin T AUC supporting an increase in myocardial injury early after reperfusion in patients receiving alteplase. There was no differences in MACE at one year suggesting no long-term clinical sequelae.

Abstract
AIMS AND METHOD In the context of increasing recognition of the role of nature in well-being, but limited evidence for specific patient groups, we describe a mixed-methods evaluation of a 10-week green care intervention (a woodland group) for 18- to 30-year-olds who had experienced a first episode of psychosis. Data were collected using the Questionnaire on the Process of Recovery (QPR), semi-structured service evaluation questionnaires, the NHS Friends and Family Test (FFT), and focus group analysis. RESULTS All participants present at week 10 (n = 5) would recommend this group to others; 4/8 participants showed reliable improvement on QPR outcome measures. Thematic analysis identified themes of connection with nature and others, development of a sense of well-being and 'peacefulness' and new perspectives on psychotic experience. CLINICAL IMPLICATIONS This small retrospective evaluation describes patient-reported benefits, feasibility and acceptability of green care interventions within early intervention in psychosis services (EIS).

Background
The COVID-19 pandemic has had a profound effect on healthcare delivery. Here we describe the effect of repurposing of a research Computed Tomography scanner on clinical care of cardiology patients in an urban academic medical centre which did not have routine access to CCTA prior to the pandemic.
Patients requiring invasive coronary angiography require transfer to a regional cardiac centre (no ICA available on site).
Purpose
We investigated the effect of CCTA on i) diagnostic certainty ii) avoidance of clinician defined unnecessary invasive angiography in hospitalised patients.
Methods
This was a prospective, longitudinal cohort study involving hospitalized patients admitted to an urban academic medical centre (catchment population 650 000) between March 29 and September 21, 2020. Routinely collected (usual care) data were gathered by clinicians who were members of the usual care medical team and ethics approval or explicit patient consent was not required. High-sensitivity Troponin-I was measured on admission and 3- and 6– hours after if mandated (Abbott Architect TnI assay).
A 320-detector scanner (Aquilon ONE, Canon) was used. Intravenous metoprolol was used where required to control the heart rate (target 60 b.p.m.) and sublingual glyceryl trinitrate will be given to all patients immediately before the scan acquisition.
Results
Forty-three patients underwent inpatient CCTA, mean age: 61 ± 13 years (range 30-88y), 54% female. The presenting complaint was typical chest pain in 28 (65%), atypical chest pain in 10 (23%), and a variety of symptoms in 5 (12%) including palpitations, syncope, breathlessness.
Thirty-six (84%) of patients had a detectable TnI above the 99% centile. Median(IQR) peak TnI was 127 (33-635)ng/L.
CCTA was carried out on average 1 day post request.
CCTA resulted in an improvement in clinician diagnostic certainty (Initial review: 21% yes, 79% probable, post-CCTA review: 84% yes, 16% probable) in providing a diagnosis.
21 (49%) of invasive coronary angiograms were avoided due to CCTA, whilst an inpatient invasive coronary angiogram (ICA) was performed in 4(9%) due to CCTA demonstrating significant disease, and in 2(%) the ICA was changed from out-patient to in-patient. Three ICA tests were requested as OP due to CCTA findings. CCTA did not overestimate disease severity in this cohort.
We saved 21 inter hospital transfers for ICA during this time period.
Using NHS England cost tariffs, a cost saving of >£36,000 was made for using CCTA instead of ICA in these 21 patients who would have required ICA.
Conclusion
Inpatient CCTA resulted in greater clinician diagnostic confidence, avoidance of unnecessary invasive angiograms and a significant cost saving. This also reduced the duration of patient stay, reducing the potential exposure of patients to COVID-19.

Abstract
Aims Fractional flow reserve (FFRCT) using computed tomography coronary angiography (CTCA) determines both the presence of coronary artery disease and vessel-specific ischaemia. We tested whether an evaluation strategy based on FFRCT would improve economic and clinical outcomes compared with standard care. Methods and results Overall, 1400 patients with stable chest pain in 11 centres were randomized to initial testing with CTCA with selective FFRCT (experimental group) or standard clinical care pathways (standard group). The primary endpoint was total cardiac costs at 9 months. Secondary endpoints were angina status, quality of life, major adverse cardiac and cerebrovascular events, and use of invasive coronary angiography. Randomized groups were similar at baseline. Most patients had an initial CTCA: 439 (63%) in the standard group vs. 674 (96%) in the experimental group, 254 of whom (38%) underwent FFRCT. Mean total cardiac costs were higher by £114 (+8%) in the experimental group, with a 95% confidence interval from −£112 (−8%) to +£337 (+23%), though the difference was not significant (P = 0.10). Major adverse cardiac and cerebrovascular events did not differ significantly (10.2% in the experimental group vs. 10.6% in the standard group) and angina and quality of life improved to a similar degree over follow-up in both randomized groups. Invasive angiography was reduced significantly in the experimental group (19% vs. 25%, P = 0.01). Conclusion A strategy of CTCA with selective FFRCT in patients with stable angina did not differ significantly from standard clinical care pathways in cost or clinical outcomes, but did reduce the use of invasive coronary angiography.

Abstract
Hopefulness is arguably of central importance to the recovery of youth with major or complex youth depression, yet it is unclear how hopefulness can best be enhanced in treatment. A narrative synthesis of published and grey literature was combined with new insights from a youth lived-experience panel (N = 15), focusing on to what extent and how specific psychological therapies and standard mental health care scaffold hopefulness as applied to depression among 14-25-year-olds. Thirty-one studies of variable quality were included in this review; thirteen were qualitative, thirteen quantitative, and five used mixed methods. Hopefulness is an important active ingredient of psychotherapies and standard mental health care in youth depression. Evidence suggests talking and activity therapies have moderate to large effects on hopefulness and that hopefulness can be enhanced in standard mental health care. However, varying intervention effects suggest a marked degree of uncertainty. Hopefulness is best scaffolded by a positive relational environment in which there is support for identifying and pursuing personally valued goals and engaging in meaningful activity.

Abstract
BACKGROUND Voice-hearing is a transdiagnostic experience with evident negative effects on patients. Good quality measurement is needed to further elucidate the nature, impact and treatment of voice-hearing experiences across patient groups. The Hamilton Program for Schizophrenia Voices Questionnaire (HPSVQ) is a brief self-report measure which requires further psychometric evaluation. METHODS Using data from a transdiagnostic sample of 401 adult UK patients, the fit of a conceptual HPSVQ measurement model, proposing a separation between physical and emotional voice-hearing characteristics, was tested. A structural model was examined to test associations between voice-hearing, general emotional distress (depression, anxiety, stress) and wellbeing. The invariance of model parameters was examined across diagnosis and sex. RESULTS The final measurement model comprised two factors named 'voice severity' and 'voice-related distress'. The former comprised mainly physical voice characteristics and the latter mainly distress and other negative impacts. Structural model results supported voice-related distress as mediating the associations between voice severity and emotional distress and wellbeing. Model parameters were invariant across psychosis versus non-psychosis diagnosis and partially invariant across sex. Females experienced more severe and distressing voices and a more direct association between voice severity and general anxiety was evident. CONCLUSIONS The HPSVQ is a useful self-report measure of voice-hearing with some scope for further exploration and refinement. Voice-related distress appears a key mechanism by which voice severity predicts general distress and wellbeing. Whilst our data broadly support interventions targeting voice-related distress for all patients, females may benefit especially from interventions targeting voice severity and strategies for responding.

Abstract
Abstract
Background
CMR is an imaging modality recommended for multiple indications. Access to CMR is a key issue for its clinical use. We surveyed all CMR units in the UK.
Methods
An online survey of CMR units in the UK, with responses analysed by region and compared with population data.
Results
Response rate was 100% (Table). The UK performed a total of 102,886 scans in 2017, and 117,967 in 2018 representing a 1-year 14.7% increase and a 10-year increase of 573% compared to 2008 data (20,597).By head of population in 2018 there were 1,776 CMR scans per million people, with significant variation nationally and regionally, e.g. 4,256 per million in London vs. 396 per million in Wales (Figure). Mean number of scans per unit was 1,404, (range 98–10,000) with wide variation in referral to diagnostic times (mean 45.7 days, range 5–180) (Figure).
Clinical indications for CMR were: heart failure 21%, cardiomyopathy 27%, function and viability 22%, stress 24%, vascular disease 5%, valvular 5%, myocarditis/pericardial 10%, paediatric /congenital 10%, others e.g. transplant/masses 4%, with overlap. There were 358 consultants reporting CMR in 2018 (234 (65%) cardiologists and 124 (35%) radiologists). 81% of units had a CMR service for patients with pacemakers and defibrillators.
Conclusion
The survey shows the state of CMR in the UK. The 10-year growth has been remarkable, but there are wide disparities in terms of use, access and wait times with potential implications for clinical care. Action is needed to make access equitable across the UK.

Abstract
Abstract
Background
Angina is associated with impaired quality of life and an adverse prognosis.
Purpose
Prospectively evaluate quality of life and clinical outcomes in patients with angina undergoing invasive coronary angiography according to endotype: symptoms and/or signs of ischaemia and no obstructive coronary artery disease (INOCA) compared to obstructive coronary artery disease subjects managed by medical therapy, revascularization with percutaneous coronary intervention (PCI) and coronary artery bypass graft (CABG) surgery, respectively.
Methods
We conducted a prospective clinical evaluation of patients with angina undergoing clinically indicated invasive management (NCT03193294). Symptom severity and quality of life were assessed at baseline and repeated after 6 months. Comparisons between treatment groups were based on analysis of covariance general linear models adjusting for baseline score, sex, and cardiovascular risk. INOCA subjects were considered as one diagnostic group and not all subjects had invasive vasoreactivity testing.
Results
391 patients (mean age 62±10 years, 52% female) were enrolled over 12 months and classified into one of four groups: INOCA (N=185; 47%), obstructive CAD treated by PCI (N=126; 32%), obstructive CAD treated by CABG (N=48; 12%) and obstructive CAD managed with medical therapy (N=32; 8%). After adjusting for between group differences and overall risk, INOCA subjects had worse angina and worse treatment response at follow up (21% and 27% reduction in angina score compared to CAD patients revascularized with PCI and CABG respectively). INOCA subjects had numerically lower treatment response than CAD patients managed with medications (6.4 units, −12%; P=0.181). Population baseline mean Seattle Angina Questionnaire (SAQ) frequency score (60±26) and SAQ summary score (52.5±19) were similar between groups. The absolute difference was 6.4 units versus medically managed CAD (95% CI: −3.0 to 15.9; P=0.181), 11.3 units versus the CAD group undergoing PCI (6.1 to 16.5; P<0.001) and 14.3 units versus CABG (6.2 to 22.3; P=0.001). INOCA subjects had overall reduced quality of life (EQ5D index) and increased psychological distress scores versus all CAD groups at 6 months. During longer-term follow-up (median 18 months), 23 (6%) MACE events occurred with no differences between the groups (Kaplan Meier log-rank P=0.890).
Conclusion(s)
Patients with INOCA had more severe angina symptoms reflecting worse quality of life and treatment response at 6 months with similar MACE as CAD subjects even after adjustment for confounding factors. This study highlights the need for evidence-based antianginal therapies and disease-modifying treatments for angina patients regardless of the presence of obstructive coronary disease.

Abstract
Abstract
Background/Introduction
Experimental and clinical evidence supports the role of inflammation in atherosclerosis and its complications. Colchicine is an orally administered, potent anti-inflammatory medication that was shown to significantly lower the risk of ischemic cardiovascular events compared to placebo among subjects with a recent myocardial infarction (MI) in the main COLCOT trial. Patients treated with percutaneous coronary intervention (PCI) after MI represent an important subpopulation that may derive particularly important benefits from colchicine.
Purpose
To assess the impact of low-dose colchicine on cardiovascular events in subjects treated with PCI for an index MI.
Methods
We performed an international, randomized, double-blind trial involving patients recruited within 30 days after a MI (main COLCOT trial; n=4745). In this trial, patients were eligible if they had a confirmed myocardial infarction within 30 days before enrollment, had completed any planned percutaneous revascularization procedures and were treated medically according to national guidelines that included the intensive use of statins. Subjects were randomly assigned to receive oral colchicine 0.5 mg once daily or matching placebo. Among the entire COLCOT study population, 4408 subjects were treated with PCI for the index MI and form the COLCOT-PCI study population. We analyzed the time to the first positively adjudicated event of the composite of CV death, resuscitated cardiac arrest, acute MI, stroke or urgent hospitalization for angina requiring coronary revascularization (primary endpoint).
Results
In the main COLCOT trial, low-dose colchicine led to a significantly lower risk of the primary endpoint (hazard ratio, 0.77; 95% confidence interval [CI], 0.61 to 0.96; p=0.02). In the COLCOT-PCI subpopulation, low-dose colchicine was associated with a large reduction in the risk of a primary endpoint event (hazard ratio, 0.72; 95% confidence interval [CI], 0.57 to 0.92; p=0.008). The hazard ratios for individual components of the composite primary endpoint were 0.71 (95% CI, 0.37 to 1.33) for death from cardiovascular causes, 0.84 (95% CI, 0.26 to 2.75) for resuscitated cardiac arrest, 0.90 (95% CI, 0.66 to 1.21) for myocardial infarction, 0.25 (95% CI, 0.08 to 0.76) for stroke, and 0.42 (95% CI, 0.25 to 0.71) for urgent hospitalization for angina requiring coronary revascularization.
Conclusion
Low-dose colchicine markedly reduces the risk of ischemic cardiovascular events in patients treated with PCI for their index MI.

Abstract
BACKGROUND Data from studies with undergraduate and postgraduate taught students suggest that they are at an increased risk of having mental health problems, compared to the general population. By contrast, the literature on doctoral researchers (DRs) is far more disparate and unclear. There is a need to bring together current findings and identify what questions still need to be answered. METHODS We conducted a mixed methods systematic review to summarise the research on doctoral researchers' (DRs) mental health. Our search revealed 52 articles that were included in this review. RESULTS The results of our meta-analysis found that DRs reported significantly higher stress levels compared with population norm data. Using meta-analyses and meta-synthesis techniques, we found the risk factors with the strongest evidence base were isolation and identifying as female. Social support, viewing the PhD as a process, a positive student-supervisor relationship and engaging in self-care were the most well-established protective factors. CONCLUSIONS We have identified a critical need for researchers to better coordinate data collection to aid future reviews and allow for clinically meaningful conclusions to be drawn.

Abstract
AIMS This study explores the opinions and experiences of Irish Defences Forces' (IDF) graduates from University College Dublin's Diploma in Military Medicine Care (DMMC). It aims to identify which aspects of medical education are relevant for the development of military graduates in the role of Combat Medical Technician (CMT) in future. METHODS A validated Clinical Learning Environment Score tool was adapted and incorporated into an online survey. This was sent electronically to 71 graduates. Responses were anonymous. RESULTS 38 (54%) graduates responded. Student feedback was positive regarding teaching and clinical placements in the DMMC. In total 16 (42%) students reported use of their new skills in their daily work. Of the 9 (24%) deployed overseas, all used their new skills. Emergency and occupational health skills were used more frequently, while advanced skills were used rarely. CONCLUSION An increased emphasis on frequently used skills should be considered. Links to healthcare services would be of benefit to graduates in skills maintenance. Key advanced skills, such as intravenous cannulation and advanced airway management are rarely used but mechanisms to maintain them will improve the relevance of the programme to the CMT role. A change in how the IDF acknowledges qualifications may support more graduates in advancing and maintaining their career in the military medical workforce.

Abstract
AIM Mental health problems are prevalent among young people in Malaysia yet access to specialist mental health care is extremely limited. More context-specific research is needed to understand the factors affecting help-seeking in youth, when mental health problems typically have first onset. We aimed to explore the attitudes of vulnerable young Malaysians regarding mental health problems including unusual psychological experiences, help-seeking and mental health treatment. METHODS In the present study, nine young people (aged 16-23 years) from low-income backgrounds participated in a semi-structured interview about their perspectives on mental health problems, unusual psychological experiences and help-seeking. RESULTS Four themes were developed using thematic analysis. "Is it that they [have] family problems?" reflected participants' explanatory models of mental health problems. "Maybe in Malaysia" was concerned with perceptions of Malaysian culture as both encouraging of open sharing of problems and experiences, but also potentially stigmatizing. "You have to ask for help" emphasized the importance of mental health help-seeking despite potential stigma. "It depends on the person" addressed the challenges of engaging with psychological therapy. CONCLUSIONS We conclude that young people in Malaysia may hold compassionate, non-stigmatizing views towards people experiencing mental health problems and a desire to increase their knowledge and understandings. Yet societal stigma is a perceived reputational risk that may affect mental health problem disclosure and help-seeking. We suggest that efforts to improve mental health literacy would be valued by young Malaysians and could support reduced stigma and earlier help-seeking.

Abstract
AIMS Young people Not in Employment, Education and Training (NEET) are at increased risk of depression, yet mechanisms of this association are poorly understood. We hypothesised that being NEET has both behavioural and social identity consequences and that reductions in structured activity and multiple group memberships underlie increased depression in this group. Our purpose was to assess first whether depression was greater for NEET compared to non-NEET young people from the same geographical locality, and secondly, whether a loss of structured activity leading to a reduction in multiple group memberships explains the NEET-depression association. METHODS The present study was a cross-sectional between-groups design using convenience sampling. Measures of depression, structured activity and multiple group memberships were obtained from 45 NEET young people and 190 university students (non-NEET). RESULTS The NEET group reported significantly more depression symptoms compared to the non-NEET student control group. A path model specifying NEET status as a predictor of depression, with this association mediated by a reduction in structured activity and fewer multiple group memberships (standardised indirect = 0.03, unstandardised indirect = 0.62, P = 0.052, 95% bias corrected confidence intervals [0.21,1.44]), provided excellent fit to our data: χ2 (3) = 0.26, P = 0.968, comparative fit index (CFI) = 1.00, root mean square error of approximation (RMSEA)<0.01, standardized root mean square residual (SRMR) = 0.01). CONCLUSIONS Our findings suggest that depression is elevated amongst NEET young people compared to non-NEET students from the same locality. The association between NEET status and depression was partially mediated by reduced structured activity and its association with reduced multiple group memberships. Although using cross-sectional data, our findings suggest social interventions may be a key resource in ameliorating depression amongst NEET young people; through preserving engagement in structured activity and the wellbeing benefits derived from arising multiple group memberships.

Abstract
Abstract
Background
Impaired microcirculatory reperfusion worsens prognosis post-primary percutaneous coronary intervention (PCI) for ST-elevation myocardial infarction (STEMI). Intracoronary (IC) alteplase targets persisting thrombus post-reperfusion & distal embolisation. In the T-TIME trial microvascular obstruction on cardiac magnetic resonance (CMR) did not differ with IC alteplase vs placebo.
Purpose
To prospectively determine if index of microcirculatory resistance (IMR) is lower & coronary flow reserve (CFR) or resistive reserve ratio (RRR) are higher (improved) with IC alteplase, & to provide mechanistic insights.
Methods
A pre-planned substudy of the main protocol. From 2016–2017, STEMI patients from 3 UK hospitals ≤6 hrs ischaemic time were randomised in a 1:1:1 dose-ranging, double-blind design. Following standard care reperfusion, alteplase (10 or 20mg) or placebo was infused over 5–10 mins proximal to the culprit lesion pre-stenting. IMR (primary outcome), CFR & RRR (secondary outcomes) were measured in the culprit artery post-PCI. Physiology results were obscured from clinicians acquiring the data, to maintain blinding. CMR was performed 2 days & 3 months post-STEMI. Subgroup analyses were prespecified including by ischaemic time (<2 hours, 2–4 hrs, >4 hrs) & IMR threshold >32.
Results
In 144 patients (mean age 59 yrs, 80% male), IMR, CFR or RRR post-PCI did not differ with alteplase vs placebo (Table). Patients with ischaemic time <2 hrs had a dose related increase in CFR (placebo 1.2 [IQR 1.1–1.7], alteplase 10mg 1.4 [IQR 1.0–1.8], alteplase 20mg 2.0 [IQR 1.8–2.3] p=0.01 for interaction) & RRR (placebo 1.5 [IQR 1.3–1.9], alteplase 10mg 1.6 [1.1–2.2], alteplase 20mg 2.2 [2.0–2.6], p=0.03 for interaction). In subjects with post-PCI IMR>32, % ST-resolution at 60 mins was worse with alteplase 10mg vs placebo (23.1±53.9 vs 50.9±31.5) & in those with IMR≤32% ST-resolution at 60 mins was better with alteplase 20mg vs placebo (68.0±30.7 vs 39.1±43.2), p=0.002 for interaction. The CMR findings in the substudy & overall trial populations were consistent.
Main results Placebo Alteplase 10mg Alteplase 20mg (n=53) (n=41) (n=50) IMR, median (IQR) 33.0 (17.0–57.0) 22.0 (17.0–42.0) 37.0 (20.0–57.8) p=0.15 p=0.78 CFR, median (IQR) 1.3 (1.1–1.8) 1.4 (1.1–1.9) 1.5 (1.1–2.0) p=0.92 p=0.74 RRR, median (IQR) 1.6 (1.3–2.2) 1.6 (1.4–2.6) 1.8 (1.3–2.4) p=0.69 p=0.81 P-values for comparison of alteplase with placebo.
Conclusions
In acute STEMI with ischaemic time ≤6 hrs, IMR, CFR or RRR post-PCI did not differ with alteplase vs placebo. In those with shorter ischaemic times (<2 hrs) CFR & RRR, but not IMR, were improved with alteplase. We observed interactions between alteplase dose, ischaemic time & mechanisms of effect.

Abstract
Abstract
Background/Introduction
The prevalence of epicardial coronary artery disease (CAD) and coronary microvascular dysfunction (CMD) have not been studied systematically in an unselected cohort of patients with heart failure and preserved ejection fraction (HFpEF). Both types of coronary disease may play an important role in the pathophysiology and prognosis of HFpEF.
Methods
This prospective multi-centre observational study enrolled near-consecutive patients hospitalized with HFpEF. Patients underwent invasive coronary angiography. Where possible, patients also had guidewire-based assessment of fractional flow reserve, coronary flow reserve (CFR) and index of microcirculatory resistance (IMR) performed, followed by vasoreactivity testing with intracoronary acetylcholine.
Results
A total of 75 patients underwent invasive coronary angiography. Guidewire-based assessment of FFR/CFR/IMR was performed in 62 patients, and vasoreactivity testing was possible in 41 patients. Obstructive epicardial CAD was identified in 38 patients (51%). CMD (defined as a CFR <2.0 and/or IMR ≥25) was present in 66% of patients assessed and was similarly prevalent in those with and without obstructive epicardial disease (62% vs. 69%, p 0.52). During vasoreactivity testing, 24% of those assessed had evidence of coronary microvascular endothelial dysfunction. Patients with obstructive CAD were more often male (63% vs. 38%, p 0.028), and had a history of CAD (50% vs. 19%, p 0.005), diabetes mellitus (63% vs. 41%, p 0.05), and a higher E/e' on echocardiography (median 14.4 vs. 12.3, p 0.044) than those without obstructive coronary disease. Patients with CMD had higher B-type natriuretic peptide levels (median 569 vs. 197 pg/ml, p 0.036) than those without microvascular dysfunction.
Selected baseline characteristics No obstructive CAD (n=37) Obstructive CAD (n=38) p-value No CMD (n=21) CMD (n=41) p-value Age (mean, years) 72 73 0.4 74 72 0.41 Female, n (%) 23 (62%) 14 (37%) 0.028 11 (52%) 22 (54%) 0.92 CAD history, n (%) 7 (19%) 19 (50%) 0.005 7 (33%) 12 (29%) 0.74 Diabetes mellitus, n (%) 15 (41%) 24 (63%) 0.05 11 (52%) 22 (54%) 0.92 BNP (median, pg/ml) 323 315 0.9 197 569 0.036 Ejection fraction (median, %) 59 58 0.35 60 56 0.064 E/e' (median) 12.3 14.4 0.044 14.2 12.4 0.74
Study flow diagram
Conclusion
Both epicardial CAD and CMD are common in HFpEF and each may be a therapeutic target in this condition. Although it has been hypothesized that CMD may be due to endothelial dysfunction, our findings suggest that CMD is predominantly due to structural abnormalities in HFpEF.

Abstract
Abstract
Background
Microvascular obstruction affects half of patients with acute ST-segment elevation myocardial infarction and confers an adverse prognosis.
Purpose
We aimed to determine whether the efficacy and safety of a therapeutic strategy involving low-dose intra-coronary alteplase infused early after coronary reperfusion associates with ischaemic time.
Methods
We conducted a prospective, multicentre, parallel group, 1:1:1 randomised, dose-ranging trial in patients undergoing primary percutaneous coronary intervention. Ischaemic time, defined as the time from symptom onset to coronary reperfusion, was a pre-specified sub-group of interest. Between March 17, 2016, and December 21, 2017, 440 patients presenting at 11 hospitals in the UK were enrolled with follow up to 3 months. Patients with acute myocardial infarction due to occlusion of a major coronary artery presenting ≤6 hours from symptom onset were randomly assigned to treatment with placebo, alteplase 10mg or alteplase 20mg. The primary outcome was the amount of microvascular obstruction disclosed by cardiac magnetic resonance imaging at 2–7 days. Secondary outcomes included infarct size, myocardial haemorrhage, left ventricular ejection fraction, and troponin T area-under-the curve.
Results
440 patients were randomized (figure), the primary endpoint was achieved in 396 (90%), seventeen (3.9%) withdrew and all other patients were followed up to 3 months. In the primary analysis, the amount of microvascular obstruction did not differ between the groups. Their ischaemic times were: ≤2 hours, n=98; ≥2–<4 hours, n=215; and ≥4–6 hours, n=83.
In patients with an ischaemic time ≥4 hours, treatment with alteplase (10 mg, n=26; 20 mg, n=30) was associated with a dose dependent increase in the amount (mean) of microvascular obstruction (% left ventricular mass) compared to placebo (n=27) 1.14 vs. 3.11 vs. 5.20; mean difference on square root scale 0.81 (95% CI 0.21, 1.42), p=0.009. The interaction test between ischaemic time and treatment (active vs. placebo) was not statistically significant p=0.06, however when the interaction was assessed for a trend across treatment groups this did reach statistical significance, p=0.018.
Furthermore, a higher proportion of patients presenting ≥4–6 hours treated with 20 mg of alteplase had myocardial haemorrhage (59.3%) compared to the placebo group (28.0%), odds ratio 3.81 (95% CI 1.19, 12.25), p=0.025. The amount of haemorrhage was also greater; estimated mean difference 3.49 (95% CI 1.22, 5.75), p=0.0026. No between-treatment group differences for myocardial haemorrhage were observed in patients presenting with shorter ischaemic times.

Conclusions
In patients presenting with an ischaemic time ≥4 hours, adjunctive treatment with low-dose intra-coronary alteplase during primary PCI was associated with increases in microvascular obstruction and myocardial haemorrhage. The mechanism may involve haemorrhagic transformation within the infarct core.

Abstract
Abstract
Background
The Universal Definition of Myocardial Infarction recommends the 99th centile diagnostic threshold using a high-sensitivity cardiac troponin (hs-cTn) assay and the classification of patients by the etiology of myocardial injury. Whether implementation of this definition improves risk stratification, treatment or outcomes is unknown.
Methods
In a stepped-wedge cluster randomized controlled trial, we implemented a high-sensitivity troponin assay and the recommendations of the Universal Definition in 48,282 consecutive patients with suspected acute coronary syndrome across ten hospitals. In a pre-specified secondary analysis, we compared the primary outcome of myocardial infarction or cardiovascular death, and secondary outcome of non-cardiovascular death at one year across diagnostic categories as per the Fourth Universal Definition. We applied competing risks methodology in all analyses, using a cumulative incidence function and determining the cause-specific hazard ratio (csHR) for competing outcomes.
Results
Cardiac troponin concentrations were elevated in 21.5% (10,360/48,282) of all trial participants. Implementation increased the diagnosis of type 1 myocardial infarction by 11% (510/4,471), type 2 myocardial infarction by 22% (205/916), acute myocardial injury by 36% (443/1,233) and chronic myocardial injury by 43% (389/898). The risk and rate of the primary outcome was highest in those with type 1 myocardial infarction, whereas the risk and rate of non-cardiovascular death was highest in those with acute myocardial injury (Table, Figure). Despite increases in anti-platelet therapy and coronary revascularization after implementation, the primary outcome was unchanged in patients with type 1 myocardial infarction (csHR 1.00, 95% CI 0.82 to 1.21), or in any other category.
Adjusted csHR for competing outcomes Myocardial infarction or cardiovascular death Non-cardiovascular death Adjusted csHR (95% CI) Adjusted csHR (95% CI) Type 1 myocardial infarction 5.64 (5.12 to 6.22) 0.83 (0.72 to 0.96) Type 2 myocardial infarction 3.50 (2.94 to 4.15) 1.72 (1.44 to 2.06) Acute myocardial injury 4.38 (3.80 to 5.05) 2.65 (2.33 to 3.00) Chronic myocardial injury 3.88 (3.31 to 4.55) 2.06 (1.77 to 2.40) Cox regression models adjusted for age, sex, diabetes, ischaemic heart disease, season, days since trial onset and site of recruitment (as a random effect).
Cumulative incidence and number at risk
Conclusions
Implementation of the recommendations of the Universal Definition identified patients with different risks of future cardiovascular and non-cardiovascular events, but did not improve outcomes. Greater understanding of the underlying mechanisms and effective strategies for the investigation and treatment of patients with myocardial injury and infarction are required if we are to improve outcomes.
