Abstract
BACKGROUND Most cases of hypertension can be effectively treated with lifestyle changes together with medications, but within this population lies a group with more difficult to treat hypertension-those with apparent treatment-resistant hypertension (aTRH). The American Heart Association and the UK National Institute for Health and Care Excellence have both highlighted the need for further research into the prognosis of patients with resistant hypertension, both apparent and true. METHODS In 16 practices affiliated to a university research network, 646 patients had been identified with apparent treatment-resistant hypertension. To inform a planned full cohort study of these patients, we conducted a feasibility study within three practices to determine participation of practices and patients, availability of outcome measures and data collection times. RESULTS All three practices fully participated and 205/210 (98%) patients were followed up for a median of 23 months. Thirty-five outcome events of interest occurred-the most common was the new onset of retinopathy (9 cases). Eight percent (17/210) had the main composite outcome of death or serious incident cardiovascular event. Of the six patients who died, identification of cause of death was possible from practice records in five; the national General Register Office was successfully used for the final patient. There were 123 admissions, both day and overnight, recorded in 94 individual patients. Average manual systolic blood pressure measurements improved from baseline by 5 mmHg to 138 (SD 19) mmHg; diastolic remained the same at 75 (SD 12) mmHg. Average eGFR increased from 58.8 (SD17.4) to 66 (SD19.7) mls/min/1.73m2. The average time for data collection per patient was 12 mins. CONCLUSIONS This study demonstrates that the proposed methodology for a full cohort study within general practice of patients with apparent treatment hypertension is both acceptable to practices and feasible. An adequately powered subsequent follow-up study of the entire cohort appears possible.

Abstract
Just a few days after the introduction of lithium therapy to treat a 35-year old man suffering from a bipolar disorder, complaints of constipation arose. The issue persisted despite numerous trials with first and second line laxatives at adequate dose and duration over a period of several weeks. After the singular administration of highly dosed macrogol laxatives with electrolytes, a lower dosage was established as maintenance treatment, yielding promising results. However, the potential interactions as well as the possible fluctuations in serum lithium levels when combining a maintenance treatment of both lithium and laxatives remains to be evaluated.

Abstract
INTRODUCTION The obesity paradox in chronic obstructive pulmonary disease (COPD), whereby patients with higher body mass index (BMI) fare better, is poorly understood. Higher BMIs are associated with lower lung volumes and greater lung elastic recoil, a key determinant of expiratory airflow. The forced expiratory flow (25-75) (FEF25-75)/forced vital capacity (FVC) ratio reflects effort-independent expiratory airflow in the context of lung volume and could be modulated by BMI. METHODS We analysed data from the COPDGene study, an observational study of 10 192 subjects, with at least a 10 pack-year smoking history. Data were limited to subjects with BMI 20-40 kg/m2 (n=9222). Subjects were stratified according to forced expiratory volume in 1 s (FEV1) (%predicted)-quintiles. In regression analyses and Cox proportional hazard models, we analysed the association between BMI, the FEF25-75/FVC ratio, the imaging phenotype, COPD exacerbations, hospitalisations and death. RESULTS There was no correlation between BMI and FEV1(%predicted). However, a higher BMI is correlated with a higher FEF25-75/FVC ratio. In CT scans, a higher BMI was associated with less emphysema and less air trapping. In risk-adjusted models, the quintile with the highest FEF25-75/FVC ratio was associated with a 46% lower risk of COPD exacerbations (OR 0.54, p<0.001) and a 40% lower risk of death (HR 0.60, p=0.02), compared with the lowest quintile. BMI was not independently associated with these outcomes. CONCLUSIONS A higher BMI is associated with lower lung volumes and higher expiratory airflows when normalised for lung volume, as quantified by the FEF25-75/FVC ratio. A higher FEF25-75/FVC ratio is associated with a lower risk of COPD exacerbations and death and might quantify functional aspects of the paradoxical effect of higher BMIs on COPD.

Abstract
OBJECTIVE To investigate feasibility of multiple sclerosis (MS) exercise guidelines for inactive people with MS (PwMS) and to examine preliminary efficacy for walking. To investigate effect of augmenting that intervention with education based on social cognitive theory (SCT). DESIGN Pilot multicentre, double-blind, randomised, parallel, controlled trial. SETTING Community-delivered programme. PARTICIPANTS Sixty-five physically inactive PwMS walked independently, scored 0-3 on the Patient Determined Disease Steps Scale, had no MS relapse or change in MS medication in 12 weeks. INTERVENTIONS 10-week exercise plus SCT education (SCT) compared with exercise plus attention control education (CON). OUTCOME MEASURES Six-Minute Walk Test (6MWT), Timed Up and Go (TUG) test and Multiple Sclerosis Walking Scale-12 (MSWS-12). RESULTS 174 expressed interest, 92 were eligible and 65 enrolled (SCT, n=32; CON, n=33). The intervention was feasible and delivered as intended. 68% of SCT group and 50% of control group met the exercise guidelines after intervention. Using linear mixed effects models, intention-to-treat basis, there was insufficient evidence for difference between the groups over the trial (6MWT, p=0.30; TUG, p=0.4; MSWS-12, p=0.8). Using secondary analysis of a cohort with data for≥3 assessments (SCT, n=21; CON, n=20), there was significant treatment effect favouring the intervention group (p=0.04) with mean effect for 6MWT 39.0 m (95% CI 2.26 to 75.73) at 12 weeks and 40.0 m (95% CI 2.3 to 77.8) at 36 weeks. Both groups improved significantly in 6MWT following 10-week intervention (SCT, mean ∆=83.02, SD=60.1, p≤0.01; CON, mean ∆=56.92, SD=73.5, p≤0.01), TUG (SCT, ∆=-0.70, SD=1.25, p≤0.01; CON, ∆=-0.54, SD=0.95, p≤0.01) and MSWS-12 (SCT, ∆=-8.03, SD=16.18, p=0.02; CON, ∆=-0.86, SD=18.74, p=0.81). CONCLUSIONS A 10-week exercise programme based on the MS exercise guidelines for improving walking in previously inactive PwMS was feasible. There is marginal evidence of a treatment effect in favour of the exercise plus SCT intervention at 12 and 36 weeks. TRIAL REGISTRATION NUMBER NCT02301442; Results.

Abstract
In evidence-based medicine, randomised trials are regarded as a gold standard in estimating relative treatment effects. Nevertheless, a potential gain in precision is forfeited by ignoring observational evidence. We describe a simple estimator that combines treatment estimates from randomised and observational data and investigate its properties by simulation. We show that a substantial gain in estimation accuracy, compared with the estimator based solely on the randomised trial, is possible when the observational evidence has low bias and standard error. In the contrasting scenario where the observational evidence is inaccurate, the estimator automatically discounts its contribution to the estimated treatment effect. Meta-analysis extensions, combining estimators from multiple observational studies and randomised trials, are also explored.

Abstract
BACKGROUND Recent exercise guidelines for people with multiple sclerosis (MS) recommend a minimum of 30 min moderate intensity aerobic exercise and resistance exercise twice per week. This trial compared the secondary outcomes of a combined 10-week guideline based intervention and a Social Cognitive Theory (SCT) education programme with the same exercise intervention involving an attention control education. METHODS Physically inactive people with MS, scoring 0-3 on Patient Determined Disease Steps Scale, with no MS relapse or change in MS medication, were randomised to 10-week exercise plus SCT education or exercise plus attention control education conditions. Outcomes included fatigue, depression, anxiety, strength, physical activity, SCT constructs and impact of MS and were measured by a blinded assessor pre and post-intervention and 3 and 6 month follow up. RESULTS One hundred and seventy-four expressed interest, 92 were eligible and 65 enrolled. Using linear mixed effects models, the differences between groups on all secondary measures post-intervention and at follow-up were not significant. Post-hoc, exploratory, within group analysis identified improvements in both groups post intervention in fatigue (mean ∆(95% CI) SCT -4.99(-9.87, -0.21), p = 0.04, Control -7.68(-12.13, -3.23), p = 0.00), strength (SCT -1.51(-2.41, -0.60), p < 0.01, Control -1.55(-2.30, -0.79), p < 0.01), physical activity (SCT 9.85(5.45, 14.23), p < 0.01, Control 12.92(4.69, 20.89), goal setting (SCT 7.30(4.19, 10.4), p < 0.01, Control 5.96(2.92, 9.01), p < 0.01) and exercise planning (SCT 5.88(3.37, 8.39), p < 0.01, Control 3.76(1.27, 6.25), p < 0.01) that were maintained above baseline at 3 and 6 month follow up (all p < 0.05). Only the SCT group improved at 3 and 6 month follow up in physical impact of MS(-4.45(-8.68, -0.22), -4.12(-8.25, 0.01), anxiety(-1.76(-3.20, -0.31), -1.99(-3.28, -0.71), depression(-1.51(-2.89, -0.13), -1.02(-2.05, 0.01)) and cognition(5.04(2.51, 7.57), 3.05(0.81, 5.28), with a medium effect for cognition and fitness (Hedges' g 0.75(0.24, 1.25), 0.51(0.01, 1.00) at 3 month follow up. CONCLUSIONS There were no statistically significant differences between groups for the secondary outcomes once age, gender, time since diagnosis and type of MS were accounted for. However, within the SCT group only there were improvements in anxiety, depression, cognition and physical impact of MS. Exercising at the minimum guideline amount has a positive effect on fatigue, strength and PA that is sustained at 3 and 6 months following the cessation of the program.

Abstract
AIM The use of computerized mental health programs with vulnerable youth, such as early school leavers, remains relatively unstudied. This pilot study examined the feasibility of delivering a computerized cognitive behavioral therapy (cCBT) gaming intervention (SPARX-R) for young people (age 15-20 years) who have left school early and are attending Youthreach, an alternative education (AE) program in Ireland. METHOD Students (n = 146) from twenty-one Youthreach Centers were randomized to SPARX-R and no-intervention control. All students within the group were included in the study whether or not they were exhibiting heightened levels of depression. Program impact was examined on both negative and positive indicators of mental health, including depression (primary outcome), generalized anxiety, general mental wellbeing, coping and emotion regulation. Assessments were conducted at baseline and post-intervention (7 weeks). Participants that provided data at post-assessment (n = 66) were included in the analysis. RESULTS The participants completed on average 5.3 modules of SPARX-R with 30% (n = 9) completing the entire program. A significant improvement in emotion regulation strategies was detected, with expressive suppression decreasing significantly in the SPARX-R group in comparison to the control (- 2.97, 95% CI - 5.48 to - 0.46, p = 0.03). CONCLUSIONS Findings suggest that SPARX-R has a positive impact on emotion regulation. The lack of significant findings on other outcome measures may be attributed to inadequate sample size, and therefore, further research with larger samples are required to establish the effectiveness of the program in reducing depression and anxiety and improving psychological wellbeing among young people attending AE.

Abstract
BACKGROUND Impaired sleep quality is common and associated with an increased risk of cardiovascular disease (CVD), thought to be mediated through adverse effects on established vascular risk factors, particularly hypertension. We determined if a web-delivered sleep intervention (sleep-hygiene education, stimulus control, and cognitive behavioral therapy) reduces blood pressure compared to vascular risk factor education (standard care) alone. METHODS Phase II randomized, blinded, controlled trial of 134 participants without CVD with mild sleep impairment and blood pressure 130-160/<110 mm Hg. The primary outcome was the difference in the mean change in 24-hour ambulatory systolic blood pressure (SBP) over 8 weeks between intervention and control groups. Secondary outcomes included measures of sleep quality and psychosocial health, namely Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory (BDI), and Beck Anxiety Inventory (BAI). RESULTS Participants in the sleep intervention group showed significantly greater improvements in sleep quality, including ISI [difference in mean improvement 2.8; 95% confidence interval (CI), 1.3-4.4], PSQI (1.1; 95% CI, 0.1-2.2), sleep condition indicator (0.8; 95% CI, 0.2-1.4), and psychosocial health, including BDI (2.0; 95% CI, 0.3-3.7) and BAI (1.4; 95% CI, 0.02-2.8). The mean improvement in 24-hour ambulatory SBP did not differ between the sleep intervention (0.9 mm Hg) and control (0.8 mm Hg) arms, (difference in mean improvement 0.1; 95% CI, -3.4 to 3.2). CONCLUSION A simple, low-cost, web-delivered sleep intervention is feasible and significantly improves sleep quality and measures of psychosocial health in individuals with mild sleep impairment but does not result in short-term improvements in blood pressure.

Abstract
AIMS To examine the clinical outcomes of screening for gestational diabetes mellitus (GDM) in primary care versus secondary care, in the Irish healthcare system. DESIGN AND METHODS A parallel group randomised controlled trial (RCT) of screening for GDM in primary versus secondary care was used to examine (i) prevalence, (ii) gestational week of screen, (iii) time to access specialist care, and (iv) maternal and neonatal outcomes. In total 781 women were recruited for screening in primary care (n=391) or secondary care (n=390). RESULTS The prevalence of GDM and gestational week of screen were similar in both locations. There was a trend towards a longer time to access diabetes care in primary care (24days) versus secondary care (19days), a difference of 5days (p=0.09). Women screened in primary care also showed a trend towards a higher rate of large for gestational age (LGA) infants (20%) than those screened in secondary care (14.7%), (p=0.09). There were no differences between groups in maternal outcomes. CONCLUSIONS This RCT suggests that screening for GDM in secondary care may be associated with potentially faster time to access specialist antenatal diabetes care and possibly lower LGA rates. Further research is needed to clarify these findings and to improve the delay in accessing specialist care requires an urgent focus. Further research is needed to test these findings in other health systems.

Abstract
INTRODUCTION Sexual problems are common with cardiovascular disease, and can negatively impact quality of life. To address sexual problems, guidelines have identified the importance of sexual counselling during cardiac rehabilitation, yet this is rarely provided. The Cardiac Health and Relationship Management and Sexuality (CHARMS) intervention aims to improve the provision of sexual counselling in cardiac rehabilitation in Ireland. METHODS AND ANALYSIS This is a multicentre pilot study for the CHARMS intervention, a complex, multilevel intervention delivered within hospital-based cardiac rehabilitation programmes. The intervention includes (1) training in sexual counselling for staff, (2) a staff-led patient education and support intervention embedded within the cardiac rehabilitation programme, (3) a patient information booklet and (4) an awareness raising poster. The intervention will be delivered in two randomly selected cardiac rehabilitation centres. In each centre 30 patients will be recruited, and partners will also be invited to participate. Data will be collected from staff and patients/partners at T1 (study entry), T2 (3-month follow-up) and T3 (6-month follow-up). The primary outcome for patients/partners will be scores on the Sexual Self-Perception and Adjustment Questionnaire. Secondary outcomes for patients/partners will include relationship satisfaction; satisfaction with and barriers to sexual counselling in services; sexual activity, functioning and knowledge; physical and psychological well-being. Secondary outcomes for staff will include sexuality-related practice; barriers to sexual counselling; self-ratings of capability, opportunity and motivation; sexual attitudes and beliefs; knowledge of cardiovascular disease and sex. Fidelity of intervention delivery will be assessed using trainer self-reports, researcher-coded audio recordings and exit interviews.

Abstract
Chronic diseases tend to depend on a large number of risk factors, both environmental and genetic. Average attributable fractions were introduced by Eide and Gefeller as a way of partitioning overall disease burden into contributions from individual risk factors; this may be useful in deciding which risk factors to target in disease interventions. Here, we introduce new estimation methods for average attributable fractions that are appropriate for both case–control designs and prospective studies. Confidence intervals, derived using Monte Carlo simulation, are also described. Finally, we introduce a novel approximation for the sample average attributable fraction that will ensure a computationally tractable approach when the number of risk factors is large. An R package, [Formula: see text], implementing the methods described in this manuscript can be downloaded from the CRAN repository.

Abstract
Rapid and uncontrolled urbanisation across low and middle-income countries is leading to ever expanding numbers of urban poor, defined here as slum dwellers and the homeless. It is estimated that 828 million people are currently living in slum conditions. If governments, donors and NGOs are to respond to these growing inequities they need data that adequately represents the needs of the urban poorest as well as others across the socio-economic spectrum.We report on the findings of a special session held at the International Conference on Urban Health, Dhaka 2015. We present an overview of the need for data on urban health for planning and allocating resources to address urban inequities. Such data needs to provide information on differences between urban and rural areas nationally, between and within urban communities. We discuss the limitations of data most commonly available to national and municipality level government, donor and NGO staff. In particular we assess, with reference to the WHO's Urban HEART tool, the challenges in the design of household surveys in understanding urban health inequities.We then present two novel approaches aimed at improving the information on the health of the urban poorest. The first uses gridded population sampling techniques within the design and implementation of household surveys and the second adapts Urban HEART into a participatory approach which enables slum residents to assess indicators whilst simultaneously planning the response. We argue that if progress is to be made towards inclusive, safe, resilient and sustainable cities, as articulated in Sustainable Development Goal 11, then understanding urban health inequities is a vital pre-requisite to an effective response by governments, donors, NGOs and communities.

Abstract
A pilot randomized controlled trial that evaluated the effect of remote ischemic preconditioning (RIPC) on clinical outcomes following major vascular surgery was performed. Eligible patients were those scheduled to undergo open abdominal aortic aneurysm repair, endovascular aortic aneurysm repair, carotid endarterectomy, and lower limb revascularization procedures. Patients were randomized to RIPC or to control groups. The primary outcome was a composite clinical end point comprising any of cardiovascular death, myocardial infarction, new-onset arrhythmia, cardiac arrest, congestive cardiac failure, cerebrovascular accident, renal failure requiring renal replacement therapy, mesenteric ischemia, and urgent cardiac revascularization. Secondary outcomes were components of the primary outcome and myocardial injury as assessed by serum troponin values. The primary outcome occurred in 19 (19.2%) of 99 controls and 14 (14.1%) of 99 RIPC group patients ( P = .446). There were no significant differences in secondary outcomes. Our trial generated data that will guide future trials. Further trials are urgently needed.

Abstract
OBJECTIVE To determine the long-term effectiveness of a complex intervention in primary care aimed at improving outcomes for patients with coronary heart disease. DESIGN A 6-year follow-up of a cluster randomised controlled trial, which found after 18 months that both total and cardiovascular hospital admissions were significantly reduced in intervention practices (8% absolute reduction). SETTING 48 general practices in the Republic of Ireland and Northern Ireland. PARTICIPANTS 903 patients with established coronary heart disease at baseline in the original trial. INTERVENTION The original intervention consisted of tailored practice and patient plans; training sessions for practitioners in medication prescribing and behavioural change; and regular patient recall system. Control practices provided usual care. Following the intervention period, all supports from the research team to intervention practices ceased. PRIMARY OUTCOME hospital admissions, all cause and cardiovascular; secondary outcomes: mortality; blood pressure and cholesterol control. RESULTS At 6-year follow-up, data were collected from practice records of 696 patients (77%). For those who had died, we censored their data at the point of death and cause of death was established. There were no significant differences between the intervention and control practices in either total (OR 0.83 (95% CI 0.54 to 1.28)) or cardiovascular hospital admissions (OR 0.91 (95% CI 0.49 to 1.65)). We confirmed mortality status of 886 of the original 903 patients (98%). There were no significant differences in mortality (15% in intervention and 16% in control) or in the proportions of patients above target control for systolic blood pressure or total cholesterol. CONCLUSIONS Initial significant differences in the numbers of total and cardiovascular hospital admissions were not maintained at 6 years and no differences were found in mortality or blood pressure and cholesterol control. Policymakers need to continue to assess the effectiveness of previously efficacious programmes. TRIAL REGISTRATION NUMBER Current Controlled Trials ISRCTN24081411.

Abstract
AIMS/HYPOTHESIS It is postulated that uptake rates for gestational diabetes mellitus (GDM) screening would be improved if offered in a setting more accessible to the patient. The aim of this study was to evaluate the proportion of uptake of GDM screening in the primary vs secondary care setting, and to qualitatively explore the providers' experiences of primary care screening provision. METHODS This mixed methods study was composed of a quantitative unblinded parallel group randomised controlled trial and qualitative interview trial. The primary outcome was the proportion of uptake of screening in both the primary and secondary care settings. All pregnant women aged 18 years or over, with sufficient English and without a diagnosis or diabetes or GDM, who attended for their first antenatal appointment at one of three hospital sites along the Irish Atlantic seaboard were eligible for inclusion in this study. Seven hundred and eighty-one pregnant women were randomised using random permutated blocks to receive a 2 h 75 g OGTT in either a primary (n = 391) or secondary care (n = 390) setting. Semi-structured interviews were conducted with 13 primary care providers. Primary care providers who provided care to the population covered by the three hospital sites involved were eligible for inclusion. RESULTS Statistically significant differences were found between the primary care (n = 391) and secondary care (n = 390) arms for uptake (52.7% vs 89.2%, respectively; effect size 36.5 percentage points, 95% CI 30.7, 42.4; p < 0.001), crossover (32.5% vs 2.3%, respectively; p < 0.001) and non-uptake (14.8% vs 8.5%, respectively; p = 0.005). There were no significant differences in uptake based on the presence of a practice nurse or the presence of multiple general practitioners in the primary care setting. There was evidence of significant relationship between probability of uptake of screening and age (p < 0.001). Primary care providers reported difficulties with the conduct of GDM screening, despite recognising that the community was the most appropriate location for screening. CONCLUSIONS/INTERPRETATION Currently, provision of GDM screening in primary care in Ireland, despite its acknowledged benefits, is unfeasible due to poor uptake rates, poor rates of primary care provider engagement and primary care provider concerns.

Abstract
OBJECTIVE To evaluate a 12-week group-based lifestyle intervention programme for women with prediabetes following gestational diabetes (GDM). DESIGN A two-group, mixed methods randomized controlled trial in which 50 women with a history of GDM and abnormal glucose tolerance postpartum were randomly assigned to intervention (n = 24) or wait control (n = 26) and postintervention qualitative interviews with participants. MAIN OUTCOME MEASURES Modifiable biochemical, anthropometric, behavioural, and psychosocial risk factors associated with the development of type 2 diabetes. The primary outcome variable was the change in fasting plasma glucose (FPG) from study entry to one-year follow-up. RESULTS At one-year follow-up, the intervention group showed significant improvements over the wait control group on stress, diet self-efficacy, and quality of life. There was no evidence of an effect of the intervention on measures of biochemistry or anthropometry; the effect on one health behaviour, diet adherence, was close to significance. CONCLUSIONS Prevention programmes must tackle the barriers to participation faced by this population; home-based interventions should be investigated. Strategies for promoting long-term health self-management need to be developed and tested.

Abstract
The mean residual life function provides a clear and simple summary of the effect of a treatment or a risk factor in units of time, avoiding hazard ratios or probability scales, which require careful interpretation. Estimation of the mean residual life is complicated by the upper tail of the survival distribution not being observed as, for example, patients may still be alive at the end of the follow-up period. Various approaches have been developed to estimate the mean residual life in the presence of such right censoring. In this work, a novel semi-parametric method that combines existing non-parametric methods and an extreme value tail model is presented, where the limited sample information in the tail (prior to study termination) is used to estimate the upper tail behaviour. This approach will be demonstrated with simulated and real-life examples.

Abstract
Background MicroRNAs (miRNAs) are short non-coding RNA molecules that play a critical role in mRNA cleavage and translational repression, and are known to be altered in many diseases including breast cancer. MicroRNA-10a (miR-10a) has been shown to be deregulated in various cancer types. The aim of this study was to investigate miR-10a expression in breast cancer and to further delineate the role of retinoids and thyroxine in regulation of miR-10a. Methods Following informed patient consent and ethical approval, tissue samples were obtained during surgery. miR-10a was quantified in malignant (n = 103), normal (n = 30) and fibroadenoma (n = 35) tissues by RQ-PCR. Gene expression of Retinoic Acid Receptor beta (RARβ) and Thyroid Hormone receptor alpha (THRα) was also quantified in the same patient samples (n = 168). The in vitro effects of all-trans Retinoic acid (ATRA) and L-Thyroxine (T4) both individually and in combination, on miR-10a expression was investigated in breast cancer cell lines, T47D and SK-BR-3. Results The level of miR-10a expression was significantly decreased in tissues harvested from breast cancer patients (Mean (SEM) 2.1(0.07)) Log10 Relative Quantity (RQ)) compared to both normal (3.0(0.16) Log10 RQ, p < 0.001) and benign tissues (2.6(0.17) Log10 RQ, p < 0.05). The levels of both RARβ and THRα gene expression were also found to be decreased in breast cancer patients compared to controls (p < 0.001). A significant positive correlation was determined between miR-10a and RARβ (r = 0.31, p < 0.001) and also with THRα (r = 0.32, p < 0.001). In vitro stimulation assays revealed miR-10a expression was increased in both T47D and SK-BR-3 cells following addition of ATRA (2 fold (0.7)). While T4 alone did not stimulate miR-10a expression, the combination of T4 and ATRA was found to have a positive synergistic effect. Conclusion The data presented supports a potential tumour suppressor role for miR-10a in breast cancer, and highlights retinoic acid as a positive regulator of the microRNA.

Abstract
BACKGROUND Patients undergoing vascular surgery procedures constitute a 'high-risk' group. Fatal and disabling perioperative complications are common. Complications arise via multiple aetiological pathways. This mechanistic redundancy limits techniques to reduce complications that target individual mechanisms, for example, anti-platelet agents. Remote ischaemic preconditioning (RIPC) induces a protective phenotype in at-risk tissue, conferring protection against ischaemia-reperfusion injury regardless of the trigger. RIPC is induced by repeated periods of upper limb ischaemia-reperfusion produced using a blood pressure cuff. RIPC confers some protection against cardiac and renal injury during major vascular surgery in proof-of-concept trials. Similar trials suggest benefit during cardiac surgery. Several uncertainties remain in advance of a full-scale trial to evaluate clinical efficacy. We propose a feasibility trial to fully evaluate arm-induced RIPC's ability to confer protection in major vascular surgery, assess the incidence of a proposed composite primary efficacy endpoint and evaluate the intervention's acceptability to patients and staff. METHODS/DESIGN Four hundred major vascular surgery patients in five Irish vascular centres will be randomised (stratified for centre and procedure) to undergo RIPC or not immediately before surgery. RIPC will be induced using a blood pressure cuff with four cycles of 5 minutes of ischaemia followed by 5 minutes of reperfusion immediately before the start of operations. There is no sham intervention. Participants will undergo serum troponin measurements pre-operatively and 1, 2, and 3 days post-operatively. Participants will undergo 12-lead electrocardiograms pre-operatively and on the second post-operative day. Predefined complications within one year of surgery will be recorded. Patient and staff experiences will be explored using qualitative techniques. The primary outcome measure is the proportion of patients who develop elevated serum troponin levels in the first 3 days post-operatively. Secondary outcome measures include length of hospital and critical care stay, unplanned critical care admissions, death, myocardial infarction, stroke, mesenteric ischaemia and need for renal replacement therapy (within 30 days of surgery). DISCUSSION RIPC is novel intervention with the potential to significantly improve perioperative outcomes. This trial will provide the first evaluation of RIPC's ability to reduce adverse clinical events following major vascular surgery.

Abstract
Background Exercise has consistently yielded short-term, positive effects on health outcomes in people with multiple sclerosis (MS). However, these effects have not been maintained in the long-term. Behaviour change interventions aim to promote long-term positive lifestyle change. This study, namely, “Step it Up” will compare the effect of an exercise plus Social Cognitive Theory (SCT)-based behaviour change intervention with an exercise plus control education intervention on walking mobility among people with MS. Methods/design People with a diagnosis of MS who walk independently, score of 0–3 on the Patient Determined Disease Steps, who have not experienced an MS relapse or change in their MS medication in the last 12 weeks and who are physically inactive will be randomised to one of two study conditions. The experimental group will undergo a 10-week exercise plus SCT-based behavioural change intervention. The control group will undergo a 10-week exercise plus education intervention to control for contact. Participants will be assessed at weeks 1, 12, 24 and 36. The primary outcome will be walking mobility. Secondary outcomes will include: aerobic capacity, lower extremity muscle strength, participant adherence to the exercise programme, self-report exercise intensity, self-report enjoyment of exercise, exercise self-efficacy, outcome expectations for exercise, goal-setting for exercise, perceived benefits and barriers to exercise, perceptions of social support, physical and psychological impact of MS and fatigue. A qualitative evaluation of Step it Up will be completed among participants post-intervention. Discussion This randomised controlled trial will examine the effectiveness of an exercise plus SCT-based behaviour change intervention on walking mobility among people with MS. To this end, Step it Up will serve to inform future directions of research and clinical practice with regard to sustainable exercise interventions for people with MS.

Abstract
BACKGROUND International medical students, those attending medical school outside of their country of citizenship, account for a growing proportion of medical undergraduates worldwide. This study aimed to establish the fairness, predictive validity and acceptability of Multiple Mini Interview (MMI) in an internationally diverse student population. METHODS This was an explanatory sequential, mixed methods study. All students in First Year Medicine, National University of Ireland Galway 2012 were eligible to sit a previously validated 10 station MMI. Quantitative data comprised: demographics, selection tool scores and First Year Assessment scores. Qualitative data comprised separate focus groups with MMI Assessors, EU and Non-EU students. RESULTS 109 students participated (45% of class). Of this 41.3% (n = 45) were Non-EU and 35.8% (n = 39) did not have English as first language. Age, gender and socioeconomic class did not impact on MMI scores. Non-EU students and those for whom English was not a first language achieved significantly lower scores on MMI than their EU and English speaking counterparts (difference in mean 11.9% and 12.2% respectively, P<0.001). MMI score was associated with English language proficiency (IELTS) (r = 0.5, P<0.01). Correlations emerged between First Year results and IELTS (r = 0.44; p = 0.006; n = 38) and EU school exit exam (r = 0.52; p<0.001; n = 56). MMI predicted EU student OSCE performance (r = 0.27; p = 0.03; n = 64). In the analysis of focus group data two overarching themes emerged: Authenticity and Cultural Awareness. MMI was considered a highly authentic assessment that offered a deeper understanding of the applicant than traditional tools, with an immediate relevance to clinical practice. Cultural specificity of some stations and English language proficiency were seen to disadvantage international students. Recommendations included cultural awareness training for MMI assessors, designing and piloting culturally neutral stations, lengthening station duration and providing high quality advance information to candidates. CONCLUSION MMI is a welcome addition to assessment armamentarium for selection, particularly with regard to stakeholder acceptability. Understanding the mediating and moderating influences for differences in performance of international candidates is essential to ensure that MMI complies with the metrics of good assessment practice and principles of both distributive and procedural justice for all applicants, irrespective of nationality and cultural background.

Previous studies have reported that poor quality sleep is associated with an increased risk of hypertension and cardiovascular disease. Hypertension is the most common and important risk factor for cardiovascular disease, and even modest reductions in blood pressure can result in significant reductions in the risk of stroke and myocardial infarction. In this trial, we will determine the efficacy of an online sleep intervention in improving blood pressure, in participants with hypertension and poor sleep quality. Methods Trial design: Randomized-controlled, two-group, parallel, blinded, single-center, Phase II trial of 134 participants. Population and recruitment: Primary prevention population of participants with hypertension (systolic blood pressure, 130 to 160 mm Hg; diastolic blood pressure, <110 mm Hg) and poor sleep quality in a community setting. Intervention: Multicomponent online sleep intervention consisting of sleep information, sleep hygiene education, and cognitive behavioral therapy. Comparator: Standardized cardiovascular risk factor and lifestyle-education session (usual care). Primary outcome: Change in mean 24-hour ambulatory systolic blood pressure between baseline and 8-week follow-up. Hypertension has been selected as the primary outcome measure because of its robust association with both poor sleep quality and cardiovascular disease. Statistical analyses: Intention-to-treat analysis by using a linear mixed model. Trial registration ClinicalTrials.gov: NCT01809821, registered March 8, 2013.

Abstract
BACKGROUND There is increasing recognition of the potential use of reminiscence in maintaining or improving the quality of life of people with dementia. Despite being used widely in dementia care, evidence on the effectiveness of reminiscence remains uncertain. AIMS This study aims to evaluate the effectiveness of a structured education-based reminiscence programme-the Dementia Education Programme Incorporating Reminiscence for Staff-for people with dementia residing in long-stay care settings in Ireland. METHODS Dementia Education Programme Incorporating Reminiscence for Staff is a two-group, single-blind, cluster randomised trial conducted in long-stay residential care settings in Ireland. The primary outcome was the self-rated quality of life of residents as measured by the Quality of Life-Alzheimer's Disease instrument. RESULTS Using an intention-to-treat analysis, we found that the estimated effect of the intervention on the quality of life of residents was a non-significant 3.54 (p = 0.1; 95% confidence interval -0.83, 7.90), expressed as the difference in mean improvement between the intervention and control groups. However, the per-protocol analysis yielded a significant effect for the intervention on the quality of life of residents of 5.22 (p = 0.04; 95% confidence interval 0.11, 10.34). CONCLUSIONS Reminiscence may, in certain circumstances, be an effective care option for people with dementia in long-stay settings with potential to impact positively on the quality of life of residents.

Abstract
INTRODUCTION Internet-delivered psychological interventions among people with chronic pain have the potential to overcome environmental and economic barriers to the provision of evidence-based psychological treatment in the Irish health service context. While the use of internet-delivered cognitive-behavioural therapy programmes has been consistently shown to have small-to-moderate effects in the management of chronic pain, there is a paucity in the research regarding the effectiveness of an internet-delivered Acceptance and Commitment Therapy (ACT) programme among people with chronic pain. The current study will compare the clinical-effectiveness and cost-effectiveness of an online ACT intervention with a waitlist control condition in terms of the management of pain-related functional interference among people with chronic pain. METHODS AND ANALYSIS Participants with non-malignant pain that persists for at least 3 months will be randomised to one of two study conditions. The experimental group will undergo an eight-session internet-delivered ACT programme over an 8-week period. The control group will be a waiting list group and will be offered the ACT intervention after the 3-month follow-up period. Participants will be assessed preintervention, postintervention and at a 3-month follow-up. The primary outcome will be pain-related functional interference. Secondary outcomes will include: pain intensity, depression, global impression of change, acceptance of chronic pain and quality of life. A qualitative evaluation of the perspectives of the participants regarding the ACT intervention will be completed after the trial. ETHICS AND DISSEMINATION The study will be performed in agreement with the Declaration of Helsinki and is approved by the National University of Ireland Galway Research Ethics Committee (12/05/05). The results of the trial will be published according to the CONSORT statement and will be presented at conferences and reported in peer-reviewed journals. TRIAL REGISTRATION NUMBER ISRCTN18166896.

Abstract
Multiple Mini Interview (MMI) is a new selection tool for medical school applicants. Developed at McMaster University in 2004 it comprises a series of interview stations designed to measure performance across a range of competencies including communication skills, team work, and ethical reasoning. In September 2012, 109 First Year Medical students underwent the MMI. It consisted of 10 stations. The median total score, out of 150, was 100 (min 63, max 129). Cronbach Alphas for the 10 individual stations range from 0.74 to 0.80. Overall Cronbach Alpha of MMI items was 0.78. Staff and student feedback was positive. The outline cost per student was estimated at Euro 145. This study demonstrates that it is feasible to hold a MMI with acceptable levels of reliability and stakeholder approval in an Irish setting. Further work is ongoing to establish the concurrent and predictive validity of MMI in this cohort of medica students.

Abstract
BACKGROUND Physical inactivity is a major, potentially modifiable, risk factor for cardiovascular disease, cancer, and other chronic diseases. Effective, simple, and generalisable interventions that will increase physical activity in populations are needed. AIM To evaluate the effectiveness of a smartphone application (app) to increase physical activity in primary care. DESIGN AND SETTING An 8-week, open-label, randomised controlled trial in rural, primary care in the west of Ireland. METHOD Android smartphone users >16 years of age were recruited. All participants were provided with similar physical activity goals and information on the benefits of exercise. The intervention group was provided with a smartphone app and detailed instructions on how to use it to achieve these goals. The primary outcome was change in physical activity, as measured by a daily step count between baseline and follow-up. RESULTS A total of 139 patients were referred by their primary care health professional or self-referred. In total, 37 (27%) were screened out and 12 (9%) declined to participate, leaving 90 (65%) patients who were randomised. Of these, 78 provided baseline data (intervention = 37; control = 41) and 77 provided outcome data (intervention = 37; control = 40). The mean daily step count at baseline for intervention and control groups was 4365 and 5138 steps per day respectively. After adjusting, there was evidence of a significant treatment effect (P = 0.009); the difference in mean improvement in daily step count from week 1 to week 8 inclusive was 1029 (95% confidence interval 214 to 1843) steps per day, favouring the intervention. Improvements in physical activity in the intervention group were sustained until the end of the trial. CONCLUSION A simple smartphone app significantly increased physical activity over 8 weeks in a primary care population.

Abstract
We examine the relationship of air pollution and climatic variables to asthma admission rates of children in Galway city over a 21 year period. Paediatric asthma admissions were recorded from 1985-2005, and admission rates per thousand calculated for pre-school (1-4 years), school aged (5-14 years) and all children (1-14 years) on a monthly and annual basis. These data were compared to average monthly and annual climatic variables (rainfall, humidity, sunshine, wind speed and temperature) and black smoke levels for the city. Simple correlation and Poisson Generalized Additive Models (GAM) were used. Admission rates each month are significantly correlated with smoke levels (p = 0.007). Poisson GAM also shows a relationship between admissions and pollution (p = 0.07). Annual smoke levels impact more on admission rates of preschoolers (p = 0.04) than school age children (p = 0.10). These data suggest that air pollution is an important factor in the epidemiology of acute childhood asthma.

Abstract
Background A germline, variant in the BRCA1 3’UTR (rs8176318) was previously shown to predict breast and ovarian cancer risk in women from high-risk families, as well as increased risk of triple negative breast cancer. Here, we tested the hypothesis that this variant predicts tumor biology, like other 3’UTR mutations in cancer. Methods The impact of the BRCA1-3’UTR-variant on BRCA1 gene expression, and altered response to external stimuli was tested in vitro using a luciferase reporter assay. Gene expression was further tested in vivo by immunoflourescence staining on breast tumor tissue, comparing triple negative patient samples with the variant (TG or TT) or non-variant (GG) BRCA1 3’UTR. To determine the significance of the variant on clinically relevant endpoints, a comprehensive collection of West-Irish breast cancer patients were tested for the variant. Finally, an association of the variant with breast screening clinical phenotypes was evaluated using a cohort of women from the High Risk Breast Program at the University of Vermont. Results Luciferase reporters with the BRCA1-3’UTR-variant (T allele) displayed significantly lower gene expression, as well as altered response to external hormonal stimuli, compared to the non-variant 3’UTR (G allele) in breast cancer cell lines. This was confirmed clinically by the finding of reduced BRCA1 gene expression in triple negative samples from patients carrying the homozygous TT variant, compared to non-variant patients. The BRCA1-3’UTR-variant (TG or TT) also associated with a modest increased risk for developing breast cancer in the West-Irish cohort (OR = 1.4, 95% CI 1.1-1.8, p = 0.033). More importantly, patients with the BRCA1-3’UTR-variant had a 4-fold increased risk of presenting with Stage IV disease (p = 0.018, OR = 3.37, 95% CI 1.3-11.0). Supporting that this finding is due to tumor biology, and not difficulty screening, obese women with the BRCA1-3’UTR-variant had significantly less dense breasts (p = 0.0398) in the Vermont cohort. Conclusion A variant in the 3’UTR of BRCA1 is functional, leading to decreased BRCA1 expression, modest increased breast cancer risk, and most importantly, presentation with stage IV breast cancer, likely due to aggressive tumor biology.

Abstract
BACKGROUND Gestational diabetes mellitus (GDM) is a risk factor for the development of type 2 diabetes. Lifestyle intervention can prevent progression to type 2 diabetes in high risk populations. We designed a randomised controlled trial (RCT) to evaluate the effectiveness of an established lifestyle intervention compared to standard care for delaying diabetes onset in European women with recent GDM. Recruitment into the RCT was more challenging than anticipated with only 89 of 410 (22%) women agreeing to participate. This paper identifies factors that could enhance participation of the target population in future interventions. METHODS We hypothesised that women who agreed to participate would have higher diabetes risk profiles than those who declined, and secondly that it would be possible to predict participation on the bases of those risk factors. To test our hypothesis, we identified the subset of women for whom we had comprehensive data on diabetes risks factors 3-5 years following GDM, reducing the sample to 43 participants and 73 decliners. We considered established diabetes risk factors: smoking, daily fruit and vegetable intake, participation in exercise, family history of diabetes, glucose values and BMI scores on post-partum re-screens, use of insulin during pregnancy, and age at delivery. We also analysed narrative data from 156 decliners to further understand barriers to and facilitators of participation. RESULTS Two factors differentiated participants and decliners: age at delivery (with women older than 34 years being more likely to participate) and insulin use during pregnancy (with women requiring the use of insulin in pregnancy less likely to participate). Binary logistic regression confirmed that insulin use negatively affected the odds of participation. The most significant barriers to participation included the accessibility, affordability and practicality of the intervention. CONCLUSIONS Women with recent GDM face multiple barriers to lifestyle change. Intervention designers should consider: (i) the practicalities of participation for this population, (ii) research designs that capitalise on motivational differences between participants, (iii) alleviating concerns about long-term diabetes management. We hope this work will support future researchers in developing interventions that are more relevant, effective and successful in recruiting the desired population.

Abstract
BACKGROUND The risks associated with gestational diabetes mellitus (GDM) are well recognized, and there is increasing evidence to support treatment of the condition. However, clear guidance on the ideal approach to screening for GDM is lacking. Professional groups continue to debate whether selective screening (based on risk factors) or universal screening is the most appropriate approach. Additionally, there is ongoing debate about what levels of glucose abnormalities during pregnancy respond best to treatment and which maternal and neonatal outcomes benefit most from treatment. Furthermore, the implications of possible screening options on health care costs are not well established. In response to this uncertainty there have been repeated calls for well-designed, randomised trials to determine the efficacy of screening, diagnosis, and management plans for GDM. We describe a randomised controlled trial to investigate screening uptake rates and the clinical and cost effectiveness of screening in primary versus secondary care settings. METHODS/DESIGN This will be an unblinded, two-group, parallel randomised controlled trial (RCT). The target population includes 784 women presenting for their first antenatal visit at 12 to 18 weeks gestation at two hospitals in the west of Ireland: Galway University Hospital and Mayo General Hospital. Participants will be offered universal screening for GDM at 24 to 28 weeks gestation in either primary care (n=392) or secondary care (n=392) locations. The primary outcome variable is the uptake rate of screening. Secondary outcomes include indicators of clinical effectiveness of screening at each screening site (primary and secondary) including gestational week at time of screening, time to access antenatal diabetes services for women diagnosed with GDM, and pregnancy and neonatal outcomes for women with GDM. In addition, parallel economic and qualitative evaluations will be conducted. The trial will cover the period from the woman's first hospital antenatal visit at 12 to 18 weeks gestation, until the completion of the pregnancy.

Abstract
Patients with rheumatoid arthritis (RA) are at increased risk of osteoporosis (OP) and cardiovascular disease (CVD). Dual-energy X-ray absorptiometry scans have been validated for identifying patients with RA at risk for fracture. Reliable CVD risk stratification remains an unmet need in this population. Vertebral fracture assessment (VFA)-detected abdominal aortic calcification (AAC) has been validated as a marker of CVD in other populations, but the prevalence among patients with RA is unknown. In this study, we determined the prevalence and severity of AAC on VFA scans in a cohort of patients with RA. AAC was detected in 211 of the 603 (35%) eligible subjects; 24% were graded as severe. In multivariable analyses, the presence of AAC was significantly associated with longer disease duration and higher disease activity (p<0.05). Further studies are needed on the relationship between AAC and CVD in patients with RA.
