Abstract
BACKGROUND Diabetes mellitus (DM) is associated with a high rate of major adverse cardiac events (MACE) after de novo coronary artery percutaneous coronary intervention (PCI). Whether patients with DM undergoing PCI for in-stent restenosis (ISR) experience a similar heightened risk of MACE is not known. Hence, we sought to compare the clinical outcomes of patients with and without DM undergoing PCI for ISR. METHODS Patients undergoing first episode ISR PCI between January 2015 and December 2021 were included. The primary outcome of interest was MACE (all-cause death, myocardial infarction [MI], and target lesion revascularization [TVR]) at 1-year. RESULTS A total of 3156 patients (56.7% with DM) underwent PCI for ISR during the study period. Patients with DM were younger, more likely to be female, and had a higher prevalence of comorbidities. At 1-year follow-up, DM was associated with a higher rate of MACE (22.4% vs. 18.7%, unadjusted HR 2.03, 95%CI(1.27-3.25), p = 0.003). All-cause mortality and MI were significantly more frequent among people with DM at 1-year follow-up. The rate of TVR was similar in both groups (17.9% vs. 16.0%, unadjusted HR 1.14, 95%CI (0.94-1.37), p = 0.180). On adjusted analysis, there was no significant difference in the rate of MACE (AHR 1.07, 95%CI(0.90 - -1.29), p = 0.444), all-cause death (AHR 1.54, 95%CI(0.93-2.54), p = 0.095) or MI (AHR 1.10, 95%CI(0.74-1.63), p = 0.652). CONCLUSION ISR PCI in patients with DM was associated with a higher rate of MACE at 1-year follow-up. However, this increased risk was no longer significant after adjusting for baseline characteristics.

Abstract
OBJECTIVE A paucity of data exists on how transcatheter aortic valve implantation (TAVI) practice has evolved in Ireland. This study sought to analyse temporal trends in patient demographics, procedural characteristics, and clinical outcomes at an Irish tertiary referral centre. METHODS The prospective Mater TAVI database was divided into time tertiles based on when TAVI was performed: Group A, November 2008-April 2013; Group B, April 2013-September 2017; and Group C, September 2017-February 2022. Patient and procedural characteristics and clinical outcomes were compared across groups. RESULTS A total of 1063 (Group A, 59; Group B, 268; and Group C:, 736) patients were treated with TAVI during the study period (mean age 81.1±7.4, mean Society of Thoracic Surgeons score 5.9±5.1).Conscious sedation (Group A, 0%; Group B, 59.9%; and Group C, 90.2%, p<0.001) and femoral artery access (Group A, 76.3%; Group B, 90.7%; and Group C, 96.6%, p<0.001) were used more frequently over time. The median length of hospital stay reduced from 9 days (IQR 7, 18) in Group A to 2 days (IQR 2, 3) in Group C. In-hospital death was numerically higher in Group A compared with Group C (6.8% vs 1.9%, p=0.078). At 1-year follow-up, the rate of death and/or stroke was similar in Group A and Group C (20.3% vs 12.0%, adjusted HR 1.49, 95% CI (0.59 to 3.74)). CONCLUSION There was exponential growth in TAVI procedural volume during the study period. A minimalist approach to TAVI emerged, and this was associated with significantly shorter procedure duration and hospital stay. Clinical outcomes at 1-year follow-up did not change significantly over time.

Abstract
BACKGROUND Markers of systemic inflammation, such as high-sensitivity C-reactive protein (hsCRP), have been associated with the occurrence of major adverse cardiovascular and cerebrovascular events (MACCE) in patients undergoing percutaneous coronary intervention (PCI). Whether this risk varies according to the presence of high bleeding risk (HBR) conditions is unclear. OBJECTIVES The aim of this study was to evaluate the impact of systemic inflammation, as measured by hsCRP levels and cardiovascular outcomes in patients stratified by HBR status following PCI. METHODS Consecutive patients undergoing PCI between 2012 and 2019 with baseline hsCRP levels were included. High hsCRP was defined as >3 mg/L, and HBR was defined per the Academic Research Consortium HBR criteria. The primary outcome was MACCE, including all-cause death, myocardial infarction, or stroke at 1 year. All bleeding was assessed as a secondary outcome. RESULTS A total of 15,150 patients were included, and 40.4% (n = 6,125) qualified as HBR. The adjusted risk for MACCE was consistently higher in patients with high hsCRP in both HBR (adjusted HR [aHR]: 1.49; 95% CI: 1.18-1.87) and non-HBR (aHR: 1.87; 95% CI: 1.31-2.66) subgroups, with no interaction between HBR status and hsCRP level (Pinteraction = 0.26). Conversely, although bleeding risk was higher in the HBR cohort, hsCRP did not predict the occurrence of bleeding in either the HBR (aHR: 1.04; 95% CI: 0.82-1.31) or the non-HBR (aHR: 0.99; 95% CI: 0.71-1.39) subgroup (Pinteraction = 0.539). CONCLUSIONS Elevated hsCRP at the time of PCI is associated with a higher risk for ischemic but not bleeding events, irrespective of HBR status.

Abstract
In the past two decades, transcatheter aortic valve replacement (TAVR) has transformed the management of aortic stenosis and has become the standard of care regardless of surgical risk levels. Advances in transcatheter valve design across newer generations, improved imaging, greater operator expertise, and technical enhancements have collectively contributed to increased safety and a decline in procedural complications over this timeframe. The application of TAVR has progressively expanded to include younger patients with lower risks, who have longer life expectancies. This article offers an up-to-date review of the latest innovations in transcatheter delivery systems, devices, and its possible future indications.

Abstract
The European Radiation Dosimetry Group has carried out several different types of intercomparison (IC) exercises in the past that qualify as proficiency tests for different dosimetry systems and types of radiation. The first neutron dosemeter IC was held in 2012 (IC2012n) and was followed by a second in 2017/2018 (IC2017n). In sum, 31 Individual Monitoring Services (IMSs) entered 34 dosimetry systems in IC2012n, and 32 IMSs entered 33 dosimetry systems for IC2017n. Such exercises provided a rare opportunity to see how neutron dosemeters perform. For the IC2012n exercise, there were no applicable performance standards for neutron personal dosemeters. ISO/TC85/SC2 updated the ISO Standard 14146 in 2018 (ISO 14146:2018. Radiation protection-Criteria and performance limits for the periodic evaluation of dosimetry services) to include neutron dosimetry. It was thus possible to analyse the IC2017n exercise in accordance with the requirements given by this new standard. It is now of interest to reanalyse the results of IC2012n to quantify any modifications to the conclusions.

Abstract
BACKGROUND A complex high-risk indicated percutaneous coronary intervention (CHIP) score was recently developed from the British Cardiovascular Intervention Society (BCIS) database to define CHIP cases and their risk of in-hospital major adverse cardiac or cerebrovascular events (MACCE). OBJECTIVES The authors sought to apply this score to a contemporary U.S. population for the prediction of adverse events at 1 year following percutaneous coronary intervention (PCI). METHODS Consecutive patients undergoing PCI at a large tertiary care center between 2011 and 2020 were considered for inclusion. Patients were categorized into 4 groups based on their BCIS-CHIP score (0, 1-2, 3-4, ≥5). In each category, we assessed the 1-year risk of MACCE, a composite of all-cause death, myocardial infarction, and stroke. Secondary outcomes were the individual components of MACCE, and major bleeding at 1 year. RESULTS Among 20,799 patients included, MACCE at 1 year occurred in 1.7% patients with score 0 (reference), 3.0% with score 1 or 2 (HR: 1.72; 95% CI: 1.32-2.24), 6.1% with score 3 or 4 (HR: 3.60; 95% CI: 2.78-4.66), and 12.0% with score ≥5 (HR: 7.40; 95% CI: 5.75-9.51). Each point increase of the BCIS-CHIP score conferred a 28.0% increase of MACCE risk. The BCIS-CHIP score demonstrated good discrimination for the prediction of 1-year MACCE (C-index 0.70). The risk of secondary outcomes also progressively increased with higher score values. CONCLUSIONS In a large PCI registry, the BCIS-CHIP score had a good predictive value for MACCE at 1 year. The utilization of this score can facilitate an accurate risk stratification of patients undergoing PCI.

Abstract
A 46-year-old female presented to the emergency room with complaints of right groin pain. A palpable mass was found inferior to the right inguinal ligament. Computed tomography showed evidence of a viscera-containing hernia sac within the femoral canal. The patient was taken to the operating room for exploration of the hernia where a well-perfused right fallopian tube and right ovary were identified within the sac. These contents were reduced, and the facial defect repaired primarily. The patient was discharged and has since been seen in clinic with no residual pain or recurrence of her hernia. Femoral hernias containing gynecological structures pose unique management and only anecdotal evidence exists to guide decision making. Prompt intervention with primary repair resulted in a favorable operative outcome in this case of a femoral hernia containing adnexal structures.

OBJECTIVES To assess the correlation between the aortic valve annular plane (AVAP) obtained by preprocedural computed tomography (CT) with on-table three-dimensional rotational angiography (3DRA), in patients undergoing transcatheter aortic valve replacement (TAVR). BACKGROUND Accurate assessment of the AVAP is critical during TAVR procedures to enable optimal positioning and minimize complications. Most commonly, preprocedural CT has been used to determine the AVAP. However, this can differ from the actual AVAP obtained during the TAVR procedure. METHODS Consecutive TAVR patients at a single center undergoing both preprocedural CT and 3DRA were included in the study. The AVAP assessment by CT was performed using 3mensio software (Pie Medical Imaging). 3DRA assessment was performed using DynaCT (Siemens). RESULTS A total of 100 patients were included in the analysis. A difference of ≥5° and ≥10° in both the LAO/RAO and cranial/caudal components of the AVAP projection angle as assessed by CT and 3DRA was recorded in 39% and 10% of patients, respectively. The concordance correlation coefficient for the LAO/RAO and cranial/caudal implantation angles was 0.519 (95% CI: 0.377-0.661) and 0.558 (95% CI: 0.432-0.684), respectively. CONCLUSION Correlation between preprocedural CT and on-table 3DRA in the prediction of the actual AVAP at the time of TAVR implantation is moderate.

Abstract
Solid organ transplant recipients have demonstrated a blunted immune response to standard 2-dose vaccination against SARS-CoV-2. This study sought to determine the humoral response to heterologous booster vaccination (viral vector vaccine dose 1 and 2 + mRNA booster). Heart transplant recipients, aged 18 to 70 years of age who initially received two doses of the viral vector ChAdOx1 nCoV-19 vaccine followed by a BNT162b2 mRNA booster were recruited. A detectable antibody response in the absence of prior SARS-CoV-2 was the primary outcome measured. This was defined as an anti-spike titre of ≥0.8 U/mL on the Elecsys anti-SARS-CoV-2 S immunoassay. A total of 80 heart transplant patients (mean age 49 ± 13 years, 28% female) were included. Blood samples were drawn at a median of 30 (IQR 28-33) days after the BNT162b2 mRNA booster. The frequency of a detectable antibody response increased from 37.5% (n = 30) after dose 2 to 56% (n = 45) post dose 3 (p < 0.001). A non-detectable antibody response was significantly more common in recipients with a shorter time interval from transplantation (p < 0.001), lower likelihood of cardiac allograft vasculopathy (p = 0.003) and in those prescribed a triple versus dual immunosuppressant regime (p = 0.009) and a tacrolimus versus cyclosporine basedregimen (p = 0.007). Despite heterologous prime-booster vaccination 44% of this vulnerable population ultimately continue to have no detectable antibodies.

Abstract
The PODIUM project aims to provide real-time assessments of occupationally exposed workers by tracking their motion and combining this with a simulation of the radiation field. The present work describes the approach that would be taken in mixed neutron-gamma fields, and details the methods for generating and applying an effective dose rate map; the required fluence to effective dose conversion coefficients at intercardinal angles are also presented. A proof-of-concept of the approach is demonstrated using a simple simulated workplace field within a calibration laboratory, with corroborative comparisons made against survey instrument measurements generally confirming good agreement. Simulated tracking of an individual within the facility was performed, recording a 1.25μSv total effective dose and accounting for dose rates as low as 0.5 nSv h-1, which is much lower than anything that could be accurately measured by physical neutron dosemeters in such a field.

Abstract
Since 2012, the European Radiation Dosimetry Group (EURADOS) has developed its Strategic Research Agenda (SRA), which contributes to the identification of future research needs in radiation dosimetry in Europe. Continued scientific developments in this field necessitate regular updates and, consequently, this paper summarises the latest revision of the SRA, with input regarding the state of the art and vision for the future contributed by EURADOS Working Groups and through a stakeholder workshop. Five visions define key issues in dosimetry research that are considered important over at least the next decade. They include scientific objectives and developments in (i) updated fundamental dose concepts and quantities, (ii) improved radiation risk estimates deduced from epidemiological cohorts, (iii) efficient dose assessment for radiological emergencies, (iv) integrated personalised dosimetry in medical applications and (v) improved radiation protection of workers and the public. This SRA will be used as a guideline for future activities of EURADOS Working Groups but can also be used as guidance for research in radiation dosimetry by the wider community. It will also be used as input for a general European research roadmap for radiation protection, following similar previous contributions to the European Joint Programme for the Integration of Radiation Protection Research, under the Horizon 2020 programme (CONCERT). The full version of the SRA is available as a EURADOS report (www.eurados.org).

Abstract
ABSTRACT Patients undergoing percutaneous coronary intervention (PCI) with a clinical indication for oral anticoagulation (OAC) in addition to antiplatelet therapy (APT) necessitate rigorous evaluation of bleeding and ischemic risk to guide therapy. The optimal OAC/APT drug combination and duration of treatment is not known. This study aimed to evaluate the incidence of patients undergoing PCI with an OAC indication and the rationale for post-PCI combined OAC/APT selection in clinical practice. Consecutive patients undergoing PCI with an indication for combined OAC/APT were included in a 12-month retrospective case series. Patient demographics, clinical characteristics, prescribed OAC/APT regimens, and rationale for drug selection were reviewed. PCI was performed in 1650 patients during the study period, with an indication for OAC/APT in 133 (8.1%). A combination of aspirin, P2Y12 inhibitor, and OAC was the most frequently prescribed regime on discharge (n = 103, 81%). Dual antiplatelet therapy (DAPT) in combination with OAC was continued for a mean duration of 6.4 ± 4.4 weeks (range 3-52 weeks) before one antiplatelet was discontinued. There was no significant difference between the mean CHA2DS2-VASc or HAS-BLED score of patients with atrial fibrillation discharged on OAC/DAPT compared with alternate combinations (DAPT alone or OAC/single APT), 3.6 ± 1.3 versus 3.8 ± 1, P = 0.37 and 2.04 ± 0.7 versus 2.05 ± 1.0, P = 0.98, respectively. This case series identifies high variability in OAC/APT treatment duration and limited application of risk scoring systems and high-risk PCI characteristics in the selection of OAC/APT regimens. A more systematic patient assessment is needed to help standardize OAC/APT prescribing for this important patient cohort.

Abstract
OBJECTIVES To compare the safety of performing transfemoral transcatheter aortic valve replacement (TAVR) under conscious sedation without an anesthetist present (TAVR-NA) vs TAVR performed with an anesthetist supervising sedation (TAVR-A). BACKGROUND In almost all United States and European centers, TAVR-A represents the standard of care. There are limited data on the safety of TAVR-NA. METHODS The prospective Mater TAVR database was analyzed. Patients undergoing transfemoral TAVR under conscious sedation were identified and divided into 2 groups, ie, TAVR-NA and TAVR-A. Demographics, procedural characteristics, and clinical outcomes for each group were assessed and compared. RESULTS From a cohort of 300 patients who underwent transfemoral TAVR under conscious sedation, TAVR-NA and TAVR-A were performed in 85 patients and 215 patients, respectively. Baseline variables were similar except for a higher median Society of Thoracic Surgeons score in the TAVR-NA group vs the TAVR-A group (5.1% vs 4.4% in the TAVR-A group; P=.05). TAVR-A patients had a higher rate of conversion to general anesthesia (4.2% vs 1.2% in the TAVR-NA group; P=.29), with 1 patient in each group requiring conversion to emergency surgery. In-lab and in-hospital complication rates were similar in the TAVR-NA and TAVR-A groups (7.1% vs 6.5% [P=.86] and 8.2% vs 12.1% [P=.34], respectively). The Kaplan-Meier estimate of freedom from mortality and/or stroke at 1 month was comparable between both groups (96.5% vs 97.7%; P=.57). CONCLUSIONS In this modest-sized transfemoral TAVR cohort with a low conversion rate to emergency surgery, TAVR-NA was associated with safety outcomes that were equivalent to TAVR-A. In healthcare systems where access to TAVR may be limited by anesthetic resources, TAVR-NA appears to be a reasonable option to enable the application of this therapy.

Abstract
Working Group (WG) 6 'Computational Dosimetry' of the European Radiation Dosimetry Group promotes good practice in the application of computational methods for radiation dosimetry in radiation protection and the medical use of ionising radiation. Its cross-sectional activities within the association cover a large range of current topics in radiation dosimetry, including more fundamental studies of radiation effects in complex systems. In addition, WG 6 also performs scientific research and development as well as knowledge transfer activities, such as training courses. Monte Carlo techniques, including the use of anthropomorphic and other numerical phantoms based on voxelised geometrical models, play a strong part in the activities pursued in WG 6. However, other aspects and techniques, such as neutron spectra unfolding, have an important role as well. A number of intercomparison exercises have been carried out in the past to provide information on the accuracy with which computational methods are applied and whether best practice is being followed. Within the exercises that are still ongoing, the focus has changed towards assessing the uncertainty that can be achieved with these computational methods. Furthermore, the future strategy of WG 6 also includes an extension of the scope toward experimental benchmark activities and evaluation of cross-sections and algorithms, with the vision of establishing a gold standard for Monte Carlo methods used in medical and radiobiological applications.

Abstract
A 75-year-old was treated for prostate adenocarcinoma with brachytherapy in September 2018. A routine follow-up chest radiograph 3 months later revealed a metallic object of the same dimensions as a brachytherapy pellet located in the right ventricle. Further imaging showed the brachtherapy pellet was located in the anterobasal right ventricular endocardium close to the tricuspid valve. Frequent asymptomatic premature ventricular contractions were observed with likely origin from the left ventricular outflow tract, an area remote from the site of the pellet. The patient remains asymptomatic and subsequent imaging shows that the position of the pellet has not changed.

Abstract
STUDY PURPOSE Out-of-hospital cardiac arrests (OHCA) in the young population have only been examined in a limited number of regional studies. Hence, we sought to describe OHCA characteristics and predictors of survival to hospital discharge for the young Irish population. STUDY DESIGN An observational analysis of the national Irish OHCA register for all OHCAs aged ≤35 years between January 2012 and December 2017 was performed. The young population was categorised into three age groups: ≤1 year, 1-15 years and 16-35 years. Multivariable logistic regression was used to determine the independent predictors of survival to hospital discharge. RESULTS A total of 1295 OHCAs aged ≤35 years (26.9% female, median age 25 (IQR 17-31)) had resuscitation attempted. OHCAs in those aged ≥16 years (n=1005) were more likely to happen outside the home (38.5% vs 22.8%, p<0.001) and be of non-medical aetiology (59% vs 27.6%, p<0.001) compared with those aged <16 years (n=290). Asphyxiation, trauma and drug overdoses accounted for over 90% of the non-medical OHCAs for those 16-35 years. Overall survival to hospital discharge for the cohort was 5.1%; survival was non-significantly higher for those aged 16-35 years compared with those aged 1-15 years (6.0%, vs 2.8% p=0.93). Independent predictors of survival to hospital discharge included bystander witnessed OHCA, a shockable initial rhythm and a bystander defibrillation attempt. CONCLUSIONS The high prevalence of non-medical OHCAs and the OHCA location need to be considered when developing OHCA care pathways and preventative strategies to reduce the burden of OHCAs in the young population.

Abstract
This paper provides a summary of the Education and Training (E&T) activities that have been developed and organised by the European Radiation Dosimetry Group (EURADOS) in recent years and in the case of Training Courses over the last decade. These E&T actions include short duration Training Courses on well-established topics organised within the activity of EURADOS Working Groups (WGs), or one-day events integrated in the EURADOS Annual Meeting (workshops, winter schools, the intercomparison participants' sessions and the learning network, among others). Moreover, EURADOS has recently established a Young Scientist Grant and a Young Scientist Award. The Grant supports young scientists by encouraging them to perform research projects at other laboratories of the EURADOS network. The Award is given in recognition of excellent work developed within the WGs' work programme. Additionally, EURADOS supports the dissemination of knowledge in radiation dosimetry by promoting and endorsing conferences such as the individual monitoring (IM) series, the neutron and ion dosimetry symposia (NEUDOS) and contributions to E&T sessions at specific events.

Abstract
INTRODUCTION There is a paucity of published data on the clinical experience with trans-catheter aortic valve implantation (TAVI) in the Republic of Ireland. We sought to examine the clinical outcomes of patients with medium-term follow-up treated with TAVI at our institution. METHODS A prospective TAVI registry was used to assess the baseline demographics, procedural variables and clinical outcomes of patients treated with TAVI between the inception of the programme in 2008 and November 2017. RESULTS A total of 354 patients (mean age 80.9 ± 8.1 years, 58% male, mean STS score 6.1 ± 4.3%) were treated during the study period. Major in-hospital outcomes included in-lab death (n = 2, 0.6%), stroke (n = 8, 2.2%), device embolisation (n = 4, 1.2%), permanent pacemaker implantation (n = 22, 6.2%) and major vascular complication (n = 2, 0.6%). The median length of hospital stay was 4 days (IQR 2-8 days). The Kaplan-Meier estimate of freedom from death at 30 days and 1 year for the entire cohort was 97 ± 1% and 85.4 ± 2.3%, respectively. Trans-femoral access was associated with a significantly lower rate of death and/or stroke at 1 year compared to trans-apical access (84.9 ± 2.4% versus 60 ± 8.9%, p = 0.0005). There was no significant difference in freedom from death and/or stroke at 1 year between balloon-expandable and self-expanding valves (81.6 ± 2.6% versus 84.4 ± 7.4%, p = 0.63). CONCLUSION This study documents low complication rates and favourable rates of survival following TAVI in a consecutive series of patients undergoing TAVI at a tertiary referral centre in the Republic of Ireland. These data support the application of this therapy in the Irish context.

Abstract
Since the early 1980s, the European Radiation Dosimetry Group (EURADOS) has been maintaining a network of institutions interested in the dosimetry of ionising radiation. As of 2017, this network includes more than 70 institutions (research centres, dosimetry services, university institutes, etc.), and the EURADOS database lists more than 500 scientists who contribute to the EURADOS mission, which is to promote research and technical development in dosimetry and its implementation into practice, and to contribute to harmonisation of dosimetry in Europe and its conformance with international practices. The EURADOS working programme is organised into eight working groups dealing with environmental, computational, internal, and retrospective dosimetry; dosimetry in medical imaging; dosimetry in radiotherapy; dosimetry in high-energy radiation fields; and harmonisation of individual monitoring. Results are published as freely available EURADOS reports and in the peer-reviewed scientific literature. Moreover, EURADOS organises winter schools and training courses on various aspects relevant for radiation dosimetry, and formulates the strategic research needs in dosimetry important for Europe. This paper gives an overview on the most important EURADOS activities. More details can be found at www.eurados.org .

Abstract
INTRODUCTION A significant paravalvular leak (PVL) is estimated in at least 1-3% of patients undergoing surgical aortic and/or mitral valve replacement. Surgical repair of a PVL is associated with a 30-day mortality of approximately 10%. Percutaneous closure of PVL has emerged as an alternative to surgical repair. AIM We sought to examine the clinical outcomes of patients treated with percutaneous closure of PVL at an Irish tertiary referral centre. METHODS A prospective registry was used to record patient and procedural characteristics at the time of the PVL procedure. Medical records were retrospectively reviewed to assess clinical outcomes during the index hospitalisation and at follow-up. RESULTS A total of 26 PVL procedures were performed in 21 patients (mean age 68 ± 13 years, 76% male). Heart failure (HF), haemolysis (HL) or a combination of both was the presenting symptoms in 62%, 24% and 14% of patients, respectively. In the entire cohort, clinical success was achieved in 18 patients (86%). Clinical success was achieved more frequently when HF was the clinical indication compared to HL (100% versus 66%). Among patients presenting with isolated HF (n = 13), the mean NYHA class at baseline and follow-up was 2.5± 0.7 and 1.4± 0.7, respectively. Thirty-day mortality was 0%. There was one (3.8%) major adverse procedural complication (stroke). A total of six deaths (28%) occurred during follow-up (22 ± 13.4 months). CONCLUSIONS Patients with PVL represent a high-risk patient cohort. Percutaneous PVL offers a safe alternative to surgical PVL repair and appears particularly effective in those patients who present primarily with HF.

Abstract
Background Coronary artery ectasia (CAE) is defined as a diffuse dilatation of the diameter of the ectatic segment of the coronary artery, 1.5 times greater than that of the adjacent segment. The Tp-Te interval, P-wave and QTc dispersions are relatively new electrocardiographic markers associated with an increased risk of developing arrhythmias. Despite CAE increasing in prevalence in recent years, there is a sparsity of data available about its arrhythmogenic effect. The aim of the study was to evaluate QTc, P-wave dispersion and Tp-Te and Tp-Te/QT ratio in patients with CAE. Methods A retrospective comparative study was designed for consecutive age- and sex-matched patients. Twenty patients with isolated CAE (group 1) and 20 control subjects (group 2), with normal coronary arteries, were included. All patients presented with chest pain and coronary angiogram was indicated. Outcome measures included Tp-Te interval, Tp-Te/QT ratio, QTc dispersion and P-wave dispersion. Measurement of electrocardiogram (ECG) parameters was conducted using standardized digital online software. Descriptive and inferential statistics were performed. Results Mean Tp-Te (95.5 ± 9.01 ms) and Tp-Te/QT ratio (0.22 ± 0.02) were significantly prolonged in CAE group (Tp-Te: 84 ± 5.62 ms, P = 0.00009; Tp-Te/QT ratio: 0.20 ± 0.01, P = 0.00004). In addition, QTc (31.2 ± 3.71 ms) and P-wave dispersion (31.9 ± 5.46 ms) were significantly increased in comparison to the control group (QTc: 27.6 ± 2.82 ms, P = 0.00532 and 20 ± 3.77 ms, P = 0.00003 respectively). However, there was no difference in ventricular activation time (VAT) between groups. Conclusions CAE ECGs were found to be associated with increased Tp-Te, Tp-Te/QT ratio, QTc intervals and P-wave dispersions. This may suggest that CAE existence has a pro-arrhythmogenic nature.

Abstract
In 2012, the European Radiation Dosimetry Group (EURADOS) performed an intercomparison for neutron dosemeters that are intended to measure personal dose equivalent, Hp(10). A total of 31 participants registered with 34 dosimetry systems. The irradiation tests were chosen to provide the participants with useful information on their dosimetry systems, i.e. linearity, reproducibility, responses for different energies and angles and to simulated workplace fields. This paper gives details of the extensive information derived from the exercise.

Abstract
Since autumn 2012, the European Radiation Dosimetry Group (EURADOS) has been developing its Strategic Research Agenda (SRA), which is intended to contribute to the identification of future research needs in radiation dosimetry in Europe. The present article summarises-based on input from EURADOS Working Groups (WGs) and Voting Members-five visions in dosimetry and defines key issues in dosimetry research that are considered important for the next decades. The five visions include scientific developments required towards (a) updated fundamental dose concepts and quantities, (b) improved radiation risk estimates deduced from epidemiological cohorts, (c) efficient dose assessment for radiological emergencies, (d) integrated personalised dosimetry in medical applications and (e) improved radiation protection of workers and the public. The SRA of EURADOS will be used as a guideline for future activities of the EURADOS WGs. A detailed version of the SRA can be downloaded as a EURADOS report from the EURADOS website (www.eurados.org).

Abstract
Testicular pain is a common presentation in the emergency department. The cause includes a wide array of differentials. This report highlights a case of thrombosis of the pampiniform plexus as a rare cause of testicular pain. Doppler ultrasound should be the first line investigation. Symptomatic relief with anti-inflammatory medication should be sufficient for management.

Abstract
Epistaxis affects up to 60% of people. The basic first aid management of epistaxis is clearly stated in the literature and guidelines. Anecdotal evidence would suggest that these principles are not understood by patients and are not being conveyed to patients by their doctors. The aim was to assess current knowledge of epistaxis first aid management and identify the principle source of education in epistaxis control. This was a single centre cross-sectional study. The study population included those presenting to otolaryngology outpatients with epistaxis. 20 patients participated in this study over a 7 month period. Five (25%) patients did not use compression during an episode of epistaxis. Nine (60%) patients that used the compression technique failed to compress the lower one-third of the nose. Only two (10%) of patients identified their GP as having taught them first aid for epistaxis. Knowledge of epistaxis management is poor. Education regarding the basic principles of first aid for epistaxis may reduce morbidity and unnecessary consultations from health professionals.

Abstract
Within the framework of the EURADOS Working Group 11, a comparison of passive neutron dosemeters in high-energy neutron fields was organised in 2011. The aim of the exercise was to evaluate the response of poly-allyl-glycol-carbonate neutron dosemeters from various European dosimetry laboratories to high-energy neutron fields. Irradiations were performed at the iThemba LABS facility in South Africa with neutrons having energies up to 66 and 100 MeV.

Abstract
The European Radiation Dosimetry Group (EURADOS) IC2012n intercomparison for neutron dosemeters intended to measure personal dose equivalent, Hp(10), was performed in 2012. A total of 31 participants (27 individual monitoring services from Europe, 2 from Japan, 1 from Israel and 1 from USA) registered with 34 dosimetry systems. Participation was restricted to passive or active neutron dosemeters routinely used in individual monitoring of radiation workers. The dosimetry systems were based on thermoluminescence, polyallyldiglycol carbonate, optically stimulated luminescence, fission track detection and silicon diodes (electronic devices). The irradiation tests were chosen to provide the participants with useful information on their dosimetry systems, i.e. linearity, reproducibility, responses for different energies and angles and to simulated workplace fields. The paper will report and discuss the first analysis of the results of the EURADOS IC2012n intercomparison.

Abstract
The new recommendation issued by the International Commission on Radiological Protection (ICRP) introducing a 20-mSv annual dose limit for the eye lens stimulated an interesting debate among the radiation protection community. In the present work the problem of estimating Hp(3) for neutron realistic workplace spectra is treated, employing the recently published Hp(3)/Φ conversion coefficients with the aim of establishing a workplace-dependent relationship between Hp(10) and Hp(3). The results demonstrate that, whilst the two quantities can differ by less than 10 %, in general, Hp(10) cannot be considered a conservative estimate of Hp(3).

Abstract
The recent statement on tissue reactions issued by the International Commission on Radiological Protection in April 2011 recommends a very significant reduction in the equivalent dose annual limit for the eye lens from 150 to 20 mSv y(-1); this has stimulated a lot of interest in eye lens dosimetry in the radiation protection community. Until now no conversion coefficients were available for the operational quantity Hp(3) for neutrons. The scope of the present work was to extend previous evaluations of H*(10) and Hp(10) performed at the PTB in 1995 to provide also Hp(3) data for neutrons. The present work is also intended to complete the studies carried out on photons during the last 4 y within the European Union-funded ORAMED (optimisation of radiation protection for medical staff) project.

Abstract
African American men (AAM) demonstrate increased prostate cancer incidence and mortality rates. We investigated known prostate cancer risk factors in AAM. Prostate specific antigen (PSA) and diagnosis of high grade prostatic intraepithelial neoplasia (PIN) were significant prostate cancer predictors. However, even including AAM with low PSA (<4ng/ml), those with PIN had significantly elevated risk, compared to men without PIN (83.3% vs. 6.9%, p<0.0001). In AAM diagnosed with PIN, PSA level was no longer significant (83.3% vs. 92.3%, p=0.593 respectively). Our results suggest that a history of PIN is highly predictive of prostate cancer in AAM, and help provide PSA-independent venues for screening.

Abstract
Abstract
Background: African American men in the US have the highest incidence and mortality from prostate cancer in the world. Five-year survival rates are almost 100% of African American men diagnosed with early stage prostate cancer but only 29% for men diagnosed in the late stages of the disease. Early detection is thus the key to improved mortality and morbidity. We are investigating nanotechnologies to enhance the detection of prostate cancer biomarkers at extremely low levels in blood serum. Our goal is to engineer a multi-biomarker panel that will provide sufficiently high sensitivity and specificity such that it can be applied as a screening test and decrease prostate cancer morbidity and mortality among African-American men.
Objectives: 1.To engineer quantum dot - antibody conjugates targeting established prostate cancer biomarkers (antigens): prostate specific antigen (PSA), Kallikrein 2 (KLK2), Kallikrein 14 (KLK14), Osteoprotegerin (OPG), Antip53Ab, Caveolin-1 (Cav-1) and Interleukin-6 (IL-6) 2. To define the photoluminescence signatures of bound versus unbound QDs, reflecting antigen-antibody complex formation. 3. To derive optimal cutpoints for the sensitivity and specificity of the novel QD-conjugated biomarkers individually, and in combination, for the early detection of prostate cancer in African-American men.
Results: We have established an African American prostate cancer case-control collection. We have successfully conjugated antibodies to the above biomarkers to quantum dots and these are undergoing characterization. We have observed that the bio-conjugated QD shows a spectral shift of the maximum position on average by 4 nm in comparison to non-conjugated QDs. The shift is towards a shorter wavelengths “blue” shift for conjugated quantum dots. Its existence was confirmed with repetition of the conjugation scheme with identical parameters and the “blue” shift was observed in all repeated experiments. The PL spectral shift observed on bio-conjugated QDs with antigens may be attributed to the existence of an external local electric field that is imposed by the surrounding biomolecules (Stark effect). The shift varied depending on the different antibodies attached and on QDs of different wavelengths.
Conclusions: We have observed a spectral shift of the bio-conjugated quantum dots compared to unconjugated quantum dots. The benefit of this observation may lie in the fact that the shift is different for each antibody, thus will show a peak at different wavelengths. This effect may provide a powerful tool for multiplexing proteins for early cancer detection. This study has enormous potential impact on improved detection of this disease in the early and more curable stage which in turn would lead to decreased morbidity and mortality.
