Abstract
High-flow nasal oxygen can be administered at induction of anaesthesia for the purposes of pre-oxygenation and apnoeic oxygenation. This intervention is claimed to enhance carbon dioxide elimination during apnoea, but the extent to which this occurs remains poorly quantified. The optimal nasal oxygen flow rate for gas exchange is also unknown. In this study, 114 patients received pre-oxygenation with high-flow nasal oxygen at 50 l.min-1. At the onset of apnoea, patients were allocated randomly to receive one of three nasal oxygen flow rates: 0 l.min-1; 70 l.min-1; or 120 l.min-1. After 4 minutes of apnoea, all oxygen delivery was ceased, tracheal intubation was performed, and oxygen delivery was recommenced when SpO2 was 92%. Mean (SD) PaCO2 rise during the first minute of apnoea was 1.39 (0.39) kPa, 1.41 (0.29) kPa, and 1.26 (0.38) kPa in the 0 l.min-1, 70 l.min-1 and 120 l.min-1 groups, respectively; p = 0.16. During the second, third and fourth minutes of apnoea, mean (SD) rates of rise in PaCO2 were 0.34 (0.08) kPa.min-1, 0.36 (0.06) kPa.min-1 and 0.37 (0.07) kPa.min-1 in the 0 l.min-1, 70 l.min-1 and 120 l.min-1 groups, respectively; p = 0.17. After 4 minutes of apnoea, median (IQR [range]) arterial oxygen partial pressures in the 0 l.min-1, 70 l.min-1 and 120 l.min-1 groups were 24.5 (18.6-31.4 [12.3-48.3]) kPa; 36.6 (28.1-43.8 [9.8-56.9]) kPa; and 37.6 (26.5-45.4 [11.0-56.6]) kPa, respectively; p < 0.001. Median (IQR [range]) times to desaturate to 92% after the onset of apnoea in the 0 l.min-1, 70 l.min-1 and 120 l.min-1 groups, were 412 (347-509 [190-796]) s; 533 (467-641 [192-958]) s; and 531 (462-681 [326-1007]) s, respectively; p < 0.001. In conclusion, the rate of carbon dioxide accumulation in arterial blood did not differ significantly between apnoeic patients who received high-flow nasal oxygen and those who did not.

Abstract
BACKGROUND AND PURPOSES To assess osteoradionecrosis (ORN) incidence in a population of Irish Head and Neck cancer (HNC) patients, and assess precipitating factors that may contribute to ORN development to aid prevention. MATERIALS AND METHODS Review of 1050 HNC patients attending the Dental Oncology Clinic, CUDSH between 2010 and 2021 identified 47 cases of ORN. Medical, dental and radiotherapy records of these forty-seven patients were retrospectively reviewed. Patient-, tumour-, and treatment-related variables were investigated in association with osteoradionecrosis development. Analysis conducted using SPSS, Pearson's Chi-square test (p < 0.05), and ordinal regression model. RESULTS ORN incidence was 4.4 %. Median time from radiotherapy (RT) to ORN development was 9.5 months (range 1-98.5 months). ORN development within the mandibular surgical site was significant (p <.001), presenting at a higher Notani grade (p =.002), in mid-mandibular body region (p =.028), at radiation doses ≥ 60 Gy (p =.035), due to induced causes (p =.029), and without resolution (p =.019). CONCLUSION This is the first retrospective study of ORN in HNC patients in Ireland over 10-year period. ORN incidence was extremely low (4.4%). As patients reported high smoking/alcohol use and poor dental attendance pre-diagnosis, this suggests intensive dental intervention pre/post-diagnosis contributed to low ORN rates. Mandibular surgery pre-RT increased risk of developing ORN at the surgical site. Therefore, we recommend future treatment planning should contour the surgical site, designating it an organ at risk (OAR), assigning a dose constraint, where oncologically possible, with emphasis on reducing the hot-spot to this region; findings reinforce importance of life-long expert dental care to reduce ORN incidence.

Abstract
Background Despite an increase in the professionalism and participation of female cricket, the coaching of female pace bowling is still reliant on male-derived knowledge. Objectives To investigate the association between key male-derived kinematic and anthropometric parameters and ball release speed (BRS) in female pace bowlers. Methods Eleven female pace bowlers participated in this study. BRS, and four anthropometric and five kinematic parameters were determined. Stepwise linear regression and Pearson Product Moment correlations were used to identify anthropometric and kinematic parameters linked to BRS. Results The best predictor of BRS explaining 89% of the observed variance was the bowling shoulder angle at ball release. The best anthropometric predictor of BRS was height explaining 53% of the observed variance. Other parameters correlated with BRS included: run-up speed (r = 0.75, p = 0.013) and arm length (r = 0.61, p = 0.046). When height was controlled for, the front knee angle at front foot contact was also correlated to BRS (r = 0.68, p = 0.044). No relationship was found between trunk flexion and BRS. Conclusion Faster BRS were characterised by faster run-up speeds, straighter front knees, and delayed arm circumduction similar to male pace bowlers. The lack of relationship between trunk flexion and BRS may highlight female pace bowlers adopting a bowling technique where BRS is contributed to by trunk rotation as well as trunk flexion. This knowledge is likely to be useful in the talent identification and coaching of female pace bowlers.

Abstract
To evaluate the role of sexual behavior stigma as a determinant of depressive symptoms among men who have sex with men (MSM) and transgender women (TGW) in Kigali, Rwanda. MSM/TGW aged ≥18 years were recruited using respondent-driven sampling (RDS) between March-August, 2018. Mental health was assessed using the Patient Health Questionnaire (PHQ-9). Sexual behavior stigma from friends and family, healthcare workers, and community members was assessed using a validated instrument. Multinomial logistic regression models were used to determine the association between sexual behavior stigma and depressive symptoms and depression. Secondary analyses further compared depression and depressive symptoms among MSM and TGW. Among the 736 participants included, 14% (106/736) identified as TGW. Depression 8.9% (RDS-adjusted, 7.6%; 95% CI, 4.6-10.6) and mild/moderate symptoms of depression 26.4% (RDS-adjusted, 24.1%; 95% CI, 19.4-28.7) were common and higher among TGW compared to MSM (p < 0.001). Anticipated (41%), perceived (36%), and enacted (45%) stigmas were highly prevalent, and were also significantly higher among TGW (p < 0.001). In multivariable RDS-adjusted analysis, anticipated (relative risk ratio (RRR), 1.88; 95% CI, 1.11-3.19) and perceived (RRR, 2.06; 95% CI, 1.12-3.79) stigmas were associated with a higher prevalence of depressive symptoms. Anticipated (RRR, 4.78; 95% CI, 1.74-13.13) and enacted (RRR, 3.09; 95% CI, 1.61-5.93) stigmas were also associated with a higher prevalence of depression. In secondary analyses, the significant differences between MSM and TGW were lost after adjusting for stigma. These data demonstrate a high burden of depressive symptoms and depression among MSM/TGW in Kigali. Conceptually, stigma is a likely antecedent of mental health stress among MSM and TGW suggesting the potential utility of scaling up stigma mitigation interventions to improve the quality of life and mental health outcomes among sexual and gender minority communities in Rwanda.

Abstract
Abstract
Background
Sending copies of clinic letters to patients involves additional work for medical staff in formatting letters, administrative staff in printing and posting and is an added cost to the healthcare service. Though seen largely as good practice in some specialities, it is not done routinely in Geriatric medical services. We introduced this practice as standard in our service and wished to evaluate whether from the patient perspective, it is worthwhile.
Methods
We sent a questionnaire to n=80 older patients who were evaluated in the home setting (by the Integrated Care Team for Older People – ICTOP) or recently attended CGA (Comprehensive Geriatric Assessment) clinic or FLS (Fracture Liaison Service) clinic. We asked their opinion on the detailed medical letter sent to their General Practitioner (GP), which they received a copy of. The questionnaire could be completed by patient/carer/relative, and returned anonymously.
Results
N=30/80 were returned. Two said they found the letter difficult to understand; 1/30 said the letter caused them to worry but all said they still preferred that they had received it. N= 2 said they would like to have contributed to the letter for accuracy. All said they felt they should receive copies of all their medical correspondence. Free text comments showed overwhelming support for the process, in allowing them to self-manage their health, enhance communication with other healthcare professionals and was a useful document to refer back to when they are trying to process information during short consultations.
Conclusion
Though a small survey and limited by low response rate, older people expressed high levels of satisfaction in receiving copies of medical letters about their health. It supports the ongoing practice and should be adopted widely.

Abstract
Abstract
Background
In recent years we have seen increased awareness of the terms ‘frailty’ and ‘GEM’ in many of our Emergency Departments (ED). A clear understanding of these terms within the context of ED is essential to provide a holistic care and to best meet the needs of older adults. It has been highlighted internationally that current training programmes do not sufficiently address learning needs of trainees to optimise care of this cohort of patients. The European Geriatric Medicine Society and the European Society for Emergency Medicine has attempted to address this gap through the introduction of a core GEM curriculum in 2016, however, at a local level many EDs are not utilising this resource for a number of reasons including lack of awareness and prioritisation of other local learning needs as determined by specialist training. To address the GEM learning needs at a local level an initiative idea was trialled in the form of a GEM teaching wall with dedicated monthly topics chosen from the above curriculum.
Methods
The initiative was led by a Senior Physiotherapist working on the Frailty Intervention Therapy Team and a Senior House Officer (SHO) working in ED with collaboration from other ED members as identified. A brainstorming session took place to identify potential topics. A poster was created by the project leads each month focusing on a core topic including an overview on the subject, national/international guidelines and top tips how to best manage in ED. Relevant team members contributed to different topics. Monthly posters were displayed in the ED.
Results
The project has been successfully running for 4 months with topics including Abdominal pain, Silver trauma Delirium and Falls.
Conclusion
GEM teaching is a cornerstone of successful management of older adults presenting to our EDs. Novel MDT teaching approaches can address the identified learning gap in this area and highlight international recommendations with minimum cost.

Abstract
Background Radium 223 (Ra-223) has been successfully utilised for the treatment of men with metastatic castrate resistant prostate cancer (mCRPC). To date, no real world outcomes from its use in the Irish population have been described. Methods All men referred to our institution for Ra-223 from September 2016 to March 2019 were included. Patient demographics, treatments received, toxicities and outcomes were recorded. Overall survival (OS) and progression free survival (PFS) were analysed using the Kaplan-Meier method. Results Complete data was available for 54 men. Median age was 75 years (range 61-86 years). The median number of prior systemic treatments for mCRPC was 2 (range 0-4). Median ECOG performance status was 1 at the start of treatment and 2 at completion. The median number of Ra-223 cycles received was 4 with 37%(n=20) completing all 6 planned cycles. The most common treatment-related toxicity was fatigue seen in 52% of patients ( n=28). Improved pain scores were documented in 76% of men requiring opioid analgesia at the start of treatment. The median OS was 7 months. A good ECOG performance status, fewer than 6 bone metastases, normal alkaline phosphatase level at start of treatment and chemotherapy naivety were associated with improved OS. Conclusions Ra-223 is a moderately well tolerated palliative treatment amongst Irish men with mCRPC.

Abstract
OBJECTIVES Radiotherapy is a key cancer treatment modality but is poorly understood by doctors. We sought to evaluate radiation oncology (RO) teaching in medical schools within the United Kingdom (UK) and Republic of Ireland (RoI), as well as any impacts on RO teaching delivery from the coronavirus disease 2019 (COVID-19) pandemic. METHODS A bespoke online survey instrument was developed, piloted and distributed to oncology teaching leads at all UK and RoI medical schools. Questions were designed to capture information on the structure, format, content and faculty for RO teaching, as well as both the actual and the predicted short- and long-term impacts of COVID-19. RESULTS Responses were received from 29/41 (71%) UK and 5/6 (83%) RoI medical schools. Pre-clinical and clinical oncology teaching was delivered over a median of 2 weeks (IQR 1-6), although only 9 (27%) of 34 responding medical schools had a standalone RO module. RO teaching was most commonly delivered in clinics or wards (n = 26 and 25 respectively). Few medical schools provided teaching on the biological basis for radiotherapy (n = 11) or the RO career pathway (n = 8), and few provide teaching delivered by non-medical RO multidisciplinary team members. There was evidence of short- and long-term disruption to RO teaching from COVID-19. CONCLUSIONS RO teaching in the UK and RoI is limited with minimal coverage of relevant theoretical principles and little exposure to radiotherapy departments and their non-medical team members. The COVID-19 pandemic risks exacerbating trainee doctors' already constrained exposure to radiotherapy. ADVANCES IN KNOWLEDGE This study provides the first analysis of radiotherapy-related teaching in the UK and RoI, and the first to explore the impact of the COVID-19 pandemic on radiationoncology teaching.

Following a previous audit we delivered an education program to Emergency Department (ED) staff, on assessment of fallers and syncope. This was a repeat cycle audit on consecutive patients aged who presented with a fall/faint/collapse/blackout/syncope, to assess impact of education sessions. We also conducted a survey of n = 23 ED staff members, on role of orthostatic blood pressures and ECGs in falls assessments.
Results
Of 80 consecutive attendees with a fall, n = 41 (51%) had possible syncope as documented in the history. ECG was done within the ED in 88% vs. 51% on baseline audit however only 14% (11/80) had lying and standing blood pressure checked vs. 15% on baseline audit. This is despite our survey showing that 17/23 (74%) of ED staff felt that orthostatic BP checks were essential in all fallers, and 44% stating they measure it themselves. Brain imaging was conducted in 44% vs. 40% in baseline audit, rationale for which was unclear in some. 31% (n = 25) were admitted compared to 42% previously. Of the n = 23 admitted, 24% (n = 6) had telemetry or Holter monitor, 20% had an echocardiogram.
Conclusion
Despite an education program on assessment of older fallers, embedding it to alter practice is challenging. While the education program resulted in some improvements, it supports a dedicated team for assessing fallers in the ED. Given the low rate of further investigations into causes for those admitted, a rapid access out patient pathway is warranted. Brain imaging is carried out relatively frequently though we cannot conclude on appropriateness in this limited audit.

Abstract
Abstract
Background
Falls are a leading cause of presentation to the Emergency Department for older adults. They often are at higher risk of admission to hospital which can lead to other complications of frailty such as development of delirium or deconditioning. The risks of admission were further complicated in the past year due to COVID and its adverse outcomes on our older frail population which further highlighted the need to manage their needs at home where possible.
These above changes have led to FITT reviewing the scope of our outreach service with a focus not just on facilitating discharge but preventing further presentation or deconditioning.
Methods
The aim of the project was to identify appropriate FITT patients to provide an Outreach visit from ED within 72 hours of discharge pending needs. This service was in conjunction with the existing Integrated Care Teams/community services but an outreach visit direct from ED may have been indicated due to; staffing levels, response time, catchment area or existing rapport with the individual patient. This was pending staffing levels with reconfiguration of existing staff to support the outreach therapist.
Appropriate patients included.
-Recurrent falls.
-Unresolved delirium/advanced dementia with ongoing therapy needs.—Bridging gap while awaiting community teams.
-Equipment provision.
Results
Over 10 months 34 outreach visits completed.
Average CFS: 6.
Reasons for:
12 for safety checks.
15 equipment provision/fitting.
6 mobility reviews.
Onward referrals:
22 (PCCC OT, Physio, PHN & day hospital & ICT).
Represent within 7 days = 0.
Represent within 30 day = 14 (41%).
Conclusion
The provision of an outreach services allowed a swift therapy review in the patient’s own home & onwards referrals as indicated. Often these patients were likely to be admitted however the outreach provided a safety net to facilitate direct discharge from the ED with no representations within the first 7 days.

Abstract
Abstract
Background
Increased awareness has been given to the value of identifying frail for risk stratification and to assist in providing frailty attuned care rather than disease specific input.
This increased awareness both nationally and internationally has led to many ED’s introducing the Clinical Frailty Scale (CFS) to triage however as a service we wanted to evaluate which tool would best meet our needs to screen appropriate patients and highlight the current level of frailty within the Emergency Department.
Methods
Over a 3 day period all patients over 75 who present during core hours were screened by a senior FITT member using a number of frailty tools (CFS, THINK frail, InterRai, PRIMSA 7 & compared against our own clinical reasoning if a FITT assessment was indicated).
Results
Total Patient’s over 75 screened by screener & FITT—48.
Average age: 82.
Sex: 51.62% male.
Discharges: 57% d/c’d.
Average CFS (Screener) = 5.
Average CFS (FITT) = 5.
28/48 CFS same = 58.33%.
15/48 CFS differ by 1 point = 31.25%.
Average THINK Frail (Screener): 3.
Average THINK Frail (FITT): 2.
17/47 THINK Frail same =36%.
21/47 THINK Frail differ by 1 point = 44%.
80.85% same or within 1 point difference.
Conclusion
The CFS score provided the most consistent when comparing scores by multiple disciplines/grades.
Although the majority of older adults who scored a CFS of 1–3 or deemed non frail at triage were unlikely to benefit from a CGA, those who presented with a new fall often did require FITT input.
This research has led us to move away from our current triage tool of THINK FRAIL to the CFS, whilst continuing to assess any new falls irrespective of score.

Abstract
High-flow nasal oxygen used before and during apnoea prolongs time to desaturation at induction of anaesthesia. It is unclear how much oxygenation before apnoea prolongs this time. We randomly allocated 84 participants to 3 minutes of pre-oxygenation by one of three methods: 15 l.min-1 by facemask; 50 l.min-1 by high-flow nasal cannulae only; or 50 l.min-1 by high-flow nasal cannulae plus 15 l.min-1 by mouthpiece. We then anaesthetised and intubated the trachea of 79 participants and waited for oxygen saturation to fall to 92%. Median (IQR [range]) times to desaturate to 92% after pre-oxygenation with facemask oxygen, high-flow nasal oxygen only and high-flow nasal oxygen with mouthpiece, were: 309 (208-417 [107-544]) s; 344 (250-393 [194-585]) s; and 386 (328-498 [182-852]) s, respectively, p = 0.014. Time to desaturation after facemask pre-oxygenation was shorter than after combined nasal and mouthpiece pre-oxygenation, p = 0.006. We could not statistically distinguish high-flow nasal oxygen without mouthpiece from the other two groups for this outcome. Median (IQR [range]) arterial oxygen partial pressure after 3 minutes of pre-oxygenation by facemask, nasal cannulae and nasal cannulae plus mouthpiece, was: 49 (36-61 [24-66]) kPa; 57 (48-62 [30-69]) kPa; and 61 (55-64 [36-72]) kPa, respectively, p = 0.003. Oxygen partial pressure after 3 minutes of pre-oxygenation with nasal and mouthpiece combination was greater than after facemask pre-oxygenation, p = 0.002, and after high-flow nasal oxygen alone, p = 0.016. We did not reject the null hypothesis for the pairwise comparison of facemask pre-oxygenation and high-flow nasal pre-oxygenation, p = 0.14.

Abstract
Apnoeic oxygenation refers to oxygenation in the absence of any patient or ventilator effort to move the lungs. This phenomenon was first described in humans in the mid-20th century but has seen renewed interest in the last decade following the demonstration of apnoeic oxygenation with low-flow, and subsequently high-flow, nasal oxygen. This narrative review summarises our understanding of apnoeic oxygenation in the paediatric population. We examine the evidence supporting oxygenation via tracheal tube, modified laryngoscopes and nasal cannulae. The evidence for prolongation of safe apnoea time at induction of anaesthesia is also appraised. We explore the capacity for carbon dioxide clearance, flow rate selection with high-flow nasal oxygen and complications associated with the technique. It remains uncertain whether apnoeic oxygenation in paediatric patients results in a meaningful clinical benefit compared with standard care for outcomes such as the number of tracheal intubation attempts or the incidence of hypoxaemia. In particular, the role of apnoeic oxygenation in paediatric difficult airway management is unclear as this has not been the targeted focus of any published research to date.

Abstract
73 Background: Plasma levels of citrulline, an amino acid, are derived mainly from small bowel enterocytes. Decreased levels occur in a range of bowel conditions and citrulline has been proposed as a biomarker of bowel toxicity in pelvic radiotherapy. In a prospective study, we identify no correlation between plasma citrulline and toxicity in men receiving prostate stereotactic radiotherapy randomized to receive either pelvic nodal irradiation or not. Furthermore, citrulline levels were not significantly different between these two groups. Methods: As part of an approved clinical trial, men with intermediate to high risk prostate cancer were randomised 1:1 to prostate only or prostate + pelvic nodal radiotherapy, delivered with a rectal spacer gel in situ. The prostate and proximal seminal vesicles received 40 Gy in 5 fractions. Those randomised to the pelvic nodal arm also received 25 Gy in 5 fractions to pelvic nodes. Citrulline was measured at 10 points during treatment – consent, before fraction 1, 1 and 24 hours following fraction 1, prior to each fraction 2 – 5 and at 6 weeks’ and 3 months’ follow up. Bowel toxicity was measured by EPIC patient reported scores. Results: 16 men with follow up of at least 3 months (median 9, maximum 18 months) were analysed. Reported toxicity was significantly higher in the prostate and pelvis arm: 5 of 9 men showed a decrease in EPIC bowel domain summary score of 10 points or more compared to 0 of 7 in the prostate-only arm (p = 0.0337, two tailed Fisher’s exact test). No significant correlation between toxicity and citrulline levels was seen, nor did citrulline vary significantly between arms or fall as treatment progressed. Data analysis for a further 8 men already recruited to the study is ongoing. Conclusions: Toxicity was more commonly reported by men randomised to receive pelvic radiotherapy, suggesting that the small bowel irradiated in pelvic fields plays a role in bowel toxicity experienced during stereotactic radiotherapy. Citrulline levels showed no significant correlation with toxicity or radiation dose to small bowel. We propose that citrulline is not a useful biomarker of small bowel toxicity in this setting. Clinical trial information: NCT03253978.

Abstract
The exact physiological role for the monoamine serotonin (5-HT) in modulation of insulin secretion is yet to be fully understood. Although the presence of this monoamine in islets of Langerhans is well established, it is only with recent advances that the complex signalling network in islets involving 5-HT is being unravelled. With more than fourteen different 5-HT receptors expressed in human islets and receptor-independent mechanisms in insulin-producing β-cells, our understanding of 5-HT's regulation of insulin secretion is increasing. It is now widely accepted that failure of the pancreatic β-cell to release sufficient amounts of insulin is the main cause of type 2 diabetes (T2D), an ongoing global epidemic. In this context, 5-HT signalling may be of importance. In fact, 5-HT may serve an essential role in regulating the release of insulin and glucagon, the two main hormones that control glucose and lipid homoeostasis. In this review, we will discuss past and current understanding of 5-HT's role in the endocrine pancreas.

Abstract
The effect of celebrity diagnosis on public awareness of health conditions has already been well documented. In October 2014, Bono, the lead singer with U2, revealed publicly for the first time that he has glaucoma. This study aimed to analyze the impact of Bono's announcement on public awareness of glaucoma using Google Search trends as an indicator of public interest in the disease. Google Trends was used to examine Google Search activity for the term 'Glaucoma' between 2009 and 2015 in both Ireland and the United Kingdom. Trend analyses were performed using Microsoft Excel Version 14.3.5. Increased Google Search activity for 'Glaucoma' in October 2014 was found in both Ireland and the United Kingdom. A five-fold increase from the mean Google Search activity for this term was found in Ireland and a two-fold increase from the mean Google Search activity for this term was found in the United Kingdom. No such increase in Google Search activity occurred during each country's 2014 Glaucoma Awareness week. Google Trends is useful in medical research as a means of assessing public awareness of, and/or interest in, health related topics. Current approaches to glaucoma related health promotion in both Ireland and the United Kingdom have failed to yield an increase in on-line Google Search activity. While there was an increase in interest in glaucoma it is unclear whether this led to an increase in health seeking behaviour.

Abstract
11 Background: Approximately 20% of patients with organ confined prostate cancer (PCa) will develop disease recurrence following radical treatment (surgery or external beam radiotherapy (EBRT)). We hypothesized that a molecular subgroup of early PCa may have metastatic potential at presentation, resulting in disease recurrence. Methods: Using unsupervised hierarchical clustering of gene expression from a PCa dataset we identified a novel molecular subgroup with a transcriptional profile similar to metastatic disease. We developed a 70 gene expression assay to prospectively identify patients within the subgroup from formalin fixed and paraffin embedded tissue (FFPE). Initial assessment found the assay to be prognostic in three independent publicly available prostatectomy datasets. We therefore assessed the prognostic value of the assay in FFPE clinical samples collected from multiple international sites. FFPE tumor resections and tumor biopsy specimens were obtained from 322 surgical patients and 248 patients treated with EBRT. Regions of highest Gleason grade were identified for macrodissection, RNA extraction and gene expression analysis. Samples were dichotomized as metastatic biology assay positive or negative using a pre-specified cut-off. The association of assay results with biochemical failure (BF) and distant metastases (DM) was tested on multivariate (MVA). Results: The assay was significantly associated with BF on MVA (HR 1.67 [1.16-2.38]; p = 0.0059), (HR 2.26 [1.26-4.04]; p = 0.0062) and DM on MVA (HR 3.39 [1.88-6.12]; p = 0.0001), (HR 3.26 [1.27-8.30]; p = 0.0137) for surgery and EBRT cohorts respectively. Importantly, in a combined model, the assay demonstrated additional information to the commonly used CAPRA clinical tool for prediction of DM, HR 2.72 [2.10-3.51]; p < 0.0001, and HR 2.72 [1.42-5.20]; p = 0.0026 (Prostate Metastatic Assay combined with CAPRA-S and CAPRA respectively). Conclusions: The metastatic biology assay predicts BF and DM in PCa patients treated with surgery or EBRT. The assay may help to select patients at risk of metastatic disease for additional treatment aimed at preventing disease recurrence.

Abstract
AIM To identify whether the location of refractory patella tendinopathy (PT) has an effect on treatment modality (radial extracorporeal shock wave therapy (rESWT) or arthroscopic debridement). METHODS Between 2012 and 2014, 40 patients with PT underwent a magnetic resonance imaging (MRI) scan. This confirmed the diagnosis as either involving the tendon itself (group A, 20) or with retropatella fat pad extension (group B, 20). All patients underwent rESWT. If there was no improvement patients proceeded with surgery in the form of arthroscopic debridement (by senior authors CW and AG). Outcomes were assessed before and after treatment using the Victorian Institute of Sports Assessment-Patella (VISA-P) score. RESULTS There were 18 males and 2 females in group A and 15 males and 5 females in group B. The mean age was 41.4 years in group A (23-59) and 34.7 in group B (19-52). Seventeen of 20 in group A reported good or excellent outcomes and did not require surgical intervention (remaining three improved after second course of ESWT). All patients in group B failed to improve with rESWT, resulting in arthroscopic debridement and reported good or excellent outcomes. After 6 months, group A mean VISA-P score increased from 50.2 to 65.0 ( p = 0.01) and group B from 39.6 to 78.4 ( p = <0.001). CONCLUSION An MRI should be performed to determine the precise location of tendinosis in patients with refractory PT who fail standard conservative management. If the MRI scan shows intratendon changes only, ESWT should be performed and those with extension into the fat pad should proceed to arthroscopic debridement without rESWT.

Abstract
97 Background: Multiple randomized controlled trials (RCTs) have demonstrated the benefit of the addition of androgen deprivation therapy (ADT) to external beam radiotherapy (EBRT) in the treatment of men with localized prostate cancer (PC). Anti-androgens (AA) may have a better toxicity profile than luteinizing hormone-releasing hormone agonists (LHRHa). However, no RCT has directly compared these agents in combination with radical EBRT. We evaluated outcomes for men with localized PC treated with EBRT in conjunction with either LHRHa or AA therapy. Methods: Data from 409 consecutive patients treated in NI with radical EBRT (70-74 Gy/2Gy #) between 2005 and 2009 were reviewed. Baseline and treatment characteristics analysed comprised age at diagnosis, T stage, initial PSA (iPSA), Gleason score, age-adjusted Charlson comorbidity index (aCCI), ADT type and radiation dose. Outcomes included biochemical progression-free survival (bPFS; Phoenix), prostate cancer-specific survival (PCSS) and overall survival (OS). Cox Proportional Hazards model was used for multivariate analysis (MVA). Results: Men receiving LHRHa were significantly more likely to be older and have a higher iPSA. On MVA, factors independently associated with biochemical failure were T stage ≥ 3 and use of AA (p < 0.004 and p < 0.02 respectively). On MVA, the single independent factor for poorer OS was higher aCCI (p < 0.000015). There was a trend towards poorer OS in the LHRHa group (p = 0.087). Conclusions: An aCCI > 4 was the only independent factor for poorer OS. While there was a significantly increased rate of biochemical failure in the AA group, there was a trend towards poorer OS in the LHRHa group. This study suggests that AA may be a reasonable alternative to LHRHa therapy in men with localized PC treated with radical EBRT and ADT. [Table: see text]

Abstract
151 Background: There is a shortage of novel biomarkers in clinical use for the diagnosis and management of prostate cancer. The neutrophil-lymphocyte ratio (NLR) is a potentially useful biomarker derived from a standard full blood count from peripheral blood sampling, which is readily available and relatively inexpensive. An elevated NLR has been shown to be a poor prognostic biomarker in many advanced solid cancers, including prostate cancer (PC); however, data on NLR in non-metastatic PC have been inconsistent. The objective of this study was to evaluate baseline NLR as an independent predictor of outcome following radical radiotherapy for non-metastatic PC. Methods: Data from 477 consecutive PC patients treated with radical EBRT between 2005 and 2009 in Northern Ireland were reviewed. Outcomes included biochemical progression-free survival (bPFS; Phoenix definiton), prostate cancer-specific survival (PCSS) and overall survival (OS). A two-tailed Mann-Whitney test (significance level 5%) was used to compare NLR in each group. Results: Complete data for 409 patients were available. At a median follow-up of 75 months (range 12 – 138), 74 men (16%) had biochemical failure (BF), 12 men (3%) had died of PC, and 65 men (14%) had died of all causes. Actuarial 5-year bPFS was 91%, PCSS was 97% and OS was 89%. Median NLR was 2.42 in both the BF and non-BF groups (p = 0.78), 2.21 and 2.42 in men who died from PC and those who did not (p = 0.39) and 2.40 and 2.42 in those men who died from all causes and those men who remained alive (p = 0.83). See Table for additional data. Conclusions: In this cohort with medium- to long-term follow-up, NLR was not predictive for bPFS, PCSS or OS. Multivariate analysis of this cohort is planned. Additional prognostic biomarkers are required in PC. [Table: see text]
