Abstract
Abstract
An interlaboratory study was performed on behalf of the Food Standards Agency to evaluate the effectiveness of an affinity column cleanup liquid chromatographic (LC) method for the determination of ochratoxin A in a variety of dried fruit at European regulatory limits. To ensure homogeneity before analysis, laboratory samples are normally slurried with water in the ratio of 5 parts fruit to 4 parts water, and test materials in this form were used in the study. The test portion was extracted with acidified methanol. The extract was filtered, diluted with phosphate-buffered saline, and applied to an affinity column. The column was washed and ochratoxin A was eluted with methanol. Ochratoxin A was quantified by reversed-phase LC. The use of post-column pH shift to enhance the fluorescence of ochratoxin A by the addition of 1.1M ammonia solution to the column eluant is optional. Determination was by fluorescence. Currants, sultanas, raisins, figs, and mixed fruit (comprising dried pineapple, papaya, sultanas, prunes, dates, and banana chips), both naturally contaminated and blank (very low level), were sent to 24 collaborators in 7 European countries. Participants were asked to spike test portions of all test samples at a level equivalent to 5 ng/g ochra toxin A. Average recoveries ranged from 69 to 74%. Based on results for 5 naturally contaminated test samples (blind duplicates) the relative standard deviation for repeatability (RSDr) ranged from 4.9 to 8.7%, and the relative standard deviation for reproducibility (RSDR)rangedfrom14to28%. The method showed acceptable within-and be-tween-laboratory precision for all 5 matrixes, as evidenced by HORRAT values <1.3.

Abstract
Aims Our aim was to establish which hospitals in Ireland are running oxygen clinics and to compare oxygen prescription in hospitals to a guideline standard. Long term oxygen therapy is known to be of benefit to a specific cohort of patients but is not without risk. Methods We sent an online questionnaire and followed up by phone to representatives in Irish hospitals in which domiciliary oxygen is prescribed. We obtained responses from 32 hospitals. Results Twelve hospitals (38%) had a dedicated oxygen assessment clinic while twenty (62%) did not. Centres without oxygen clinics generally prescribed oxygen following an in-patient stay 18/23 centres (78%) and were unable to provide follow up for patients on oxygen in 6/23 centres (26%). Centres with oxygen clinics generally met criteria for initial assessment and oxygen prescription, however titration of oxygen and general follow up did not meet guideline recommendations. Conclusion Due to a lack of dedicated oxygen assessment and review services, many Irish patients are not optimally treated with domiciliary oxygen.

Abstract
PLAIN ENGLISH SUMMARY It is important for health care workers to know the needs and expectations of their patients. Therefore, service users have to be involved in research. To achieve a meaningful dialogue between service users, healthcare workers and researchers, participatory methods are needed. This paper describes how the application of a specific participatory methodology, Participatory Learning and Action (PLA) can lead to such a meaningful dialogue. In PLA all stakeholders are regarded as equal partners and collaborators in research.During 2011-2015, a European project called RESTORE used PLA in Austria, Greece, Ireland, The Netherlands and the UK to investigate how communication between primary health care workers and their migrant patients could be improved.Seventy eight migrants, interpreters, doctors, nurses and other key stakeholders (see Table 2) participated in 62 PLA sessions. These dialogues (involving discussions, activities, PLA techniques and evaluations) were generally 2-3 h long and were recorded and analysed by the researchers.Participants reported many positive experiences about their dialogues with other stakeholders. There was a positive, trusting atmosphere in which all stakeholders could express their views despite differences in social power. This made for better understanding within and across stakeholder groups. For instance a doctor changed her view on the use of interpreters after a migrant explained why this was important. Negative experiences were rare: some doctors and healthcare workers thought the PLA sessions took a lot of time; and despite the good dialogue, there was disappointment that very few migrants used the new interpreting service. ABSTRACT Background In order to be effective, primary healthcare must understand the health needs, values and expectations of the population it serves. Recent research has shown that the involvement of service users and other stakeholders and gathering information on their perspectives can contribute positively to many aspects of primary healthcare. Participatory methodologies have the potential to support engagement and dialogue between stakeholders from academic, migrant community and health service settings. This paper focuses on a specific participatory research methodology, Participatory Learning and Action (PLA) in which all stakeholders are regarded as equal partners and collaborators in research.Our research question for this paper was: "Does the application of PLA lead to meaningful engagement of all stakeholders, and if so, what elements contribute to a positive and productive inter-stakeholder dialogue?". Methods We explored the use of PLA in RESTORE, a European FP7-funded project, during 2011-2015 in 5 countries: Austria, Greece, Ireland, the Netherlands and the UK. The objective of RESTORE was to investigate and support the implementation of guidelines and training initiatives (G/TIs) to enhance communication in cross-cultural primary care consultations with migrants.Seventy eight stakeholders (migrants, interpreters, doctors, nurses and others - see Table 2) participated in a total of 62 PLA sessions (discussions, activities, evaluations) of approximately 2-3 h' duration across the five sites. During the fieldwork, qualitative data were generated about stakeholders' experiences of engagement in this dialogue, by means of various methods including participatory evaluations, researchers' fieldwork reports and researcher interviews. These were analysed following the principles of thematic analysis. Results Stakeholders involved in PLA inter-stakeholder dialogues reported a wide range of positive experiences of engagement, and very few negative experiences. A positive atmosphere during early research sessions helped to create a sense of safety and trust. This enabled stakeholders from very different backgrounds, with different social status and power, to offer their perspectives in a way that led to enhanced learning in the group - they learned with and from each other. This fostered shifts in understanding - for example, a doctor changed her view on interpreted consultations because of the input of the migrant service-users. Conclusion PLA successfully promoted stakeholder involvement in meaningful and productive inter-stakeholder dialogues. This makes it an attractive approach to enhance the further development of health research partnerships to advance primary healthcare.

Abstract
4623 Background: Nuclear magnetic resonance spectroscopy (NMRS) along with a novel method for determining absolute concentrations of metabolites were utilized to analyze expressed prostatic secretions (EPS) from men with prostate cancer (PCa) and from healthy controls. Methods: Flash frozen EPS samples from 66 men (40 with PCa and 26 controls) were analyzed by high-resolution 1H-NMR spectroscopy using a Bruker 500 MHz DRX NMR spectrometer with a 1-mm microprobe. The total number of scans per fully relaxed 1H-NMR spectrum was n = 40 with water suppression. Absolute concentrations of endogenous metabolites (citrate, spermine, myo-inositol, lactate, alanine, phosphocholine, glutamate, acetate, hydroxybutyrate) were quantified using trimethylsilyl-propionic acid as an external standard reference. Stepwise multivariable logistic regression (LR) was used to model the risk of PCa based upon the levels of the measured metabolites. Results: The average age of the EPS donors was 54.7 ± 9.8 years. The median Gleason score for the men with PCa was 6 (range 5–9). The Wilcoxon rank sum test indicated that citrate, spermine, inositol, citrate/spermine, and citrate/lactate were all significant predictors of PCa (p < .001). The LR models indicated that the absolute concentration of citrate was highly predictive of PCa with lower concentrations resulting in a higher risk of cancer. The area under the receiver operating characteristic curve (AUROC) for citrate alone was 0.79 (95% CI 0.75–0.83). Using relative concentrations (metabolite ratios) in a two-variable LR model, citrate/spermine and citrate/lactate were also predictive of PCa with an AUROC of 0.76 (95% CI 0.71–0.81). Conclusions: The results suggest that absolute concentration of citrate and its derivatives in EPS as measured by NMRS have promising potential as accurate markers of prostate cancer. No significant financial relationships to disclose.
