Abstract
INTRODUCTION Evaluating service quality and satisfaction is central to the provision of accessible and developmentally appropriate youth mental health services. However, there are limited suitable measures and a lack of published evidence on the psychometric properties of measures to assess young people's satisfaction with youth mental health services. The headspace Youth (Mental Health) Service Satisfaction Scale (YSSS) was designed and implemented to assess young people's satisfaction with headspace mental health services in Australia. This study examined the reliability and factor structure of the YSSS in a youth mental health service in Ireland. METHODS The sample comprised 1449 young people (66.2% female) aged 12-25 years (M = 16.48, SD = 2.97). Participants completed the YSSS after their final brief intervention session through Jigsaw-The National Centre for Youth Mental Health. Confirmatory factor analysis (CFA) was performed on one- and four-factor models to test findings from previous studies. Reliability was also examined. RESULTS CFA supported a single-factor structure of the YSSS, and all items were suitable for inclusion. The internal consistency of the measure was deemed acceptable (α = 0.89). CONCLUSIONS Findings suggest that the YSSS is a reliable measure for monitoring satisfaction with youth mental health services in an Irish context. The measure demonstrated a unidimensional construct of satisfaction. These findings support the broader application of the YSSS and add to existing knowledge on measuring satisfaction within youth mental health services.

Abstract
BACKGROUND Neonatal leukemoid reaction is associated with higher risk of mortality, chronic lung disease and has been associated with chorioamnionitis. Literature on extremely low birth weight infants with leukemoid reaction is limited. OBJECTIVES The aim of our study was to characterize the maternal and placental factors associated with neonatal leukemoid reaction and to describe outcomes of these ELBW infants. Our objective was to assess if there were maternal factors that would assist the decision-making process regarding the delivery of preterm infants at risk of chorioamnionitis and the sequelae of this inflammatory process. METHODS This was a retrospective case-control study performed in a single, tertiary Maternity Hospital in Dublin. Two matched controls were identified for each case based on gestation and year of birth and data was collected on both the infants and their mothers. RESULTS 7 extremely preterm neonates were identified as having a leukemoid reaction, defined as a total white cell count of >50,000 or in the first seven days of life. Baseline characteristics between the groups were similar. The median gestational age in the cases group was 24 + 4 weeks and in the control group was 24 + 1. The mean birthweight was 650 g in the cases group vs. 655 g in the control group. There was a higher percentage of males in the control group, 42.9% vs 28.6% in the cases. The preterm infants with leukemoid reaction had a longer duration of ventilation with a median of 18 days (7.5-23.5 days) compared to 6.5 days (2.8-24.5 days) in the control group. More infants in the leukemoid reaction group required inotropes for hypotension in the first 72 h after delivery (42.9% vs 7.1% in the controls, p value .169). Death or Bronchopulmonary dysplasia (BPD) occurred in 85.7% of the cases identified with a leukemoid reaction vs 71.4% of the controls matched. Median maternal CRP was higher in cases prior to delivery vs the controls (66 vs 18.1 mg/L, p-value = .2151). There was histological evidence of maternal inflammatory response in all cases with fetal inflammatory response in 71% of cases. CONCLUSIONS Leukemoid reaction in ELBW infants with evidence of maternal and fetal inflammatory response syndrome on placental histology is associated with a longer duration of initial ventilation, increased need for inotropes in the first 72 h after birth, higher rates of death, and BPD. Prospective studies are required to identify potential biomarkers such as proinflammatory cytokines, IL-6, which might aid the decision-making process in delivery.

Abstract
Fasciolosis is an endemic zoonotic parasitic disease with significant impacts on human health and both animal health and production. Early post-infection impacts on the host remain unclear. The objective of this study was to determine the changes, if any, to levels of endotoxin in cattle plasma in response to early-stage infection with Fasciola hepatica. Thirty-six (36) commercial bred cattle were experimentally infected with approximately 400 viable metacercariae. Plasma lipopolysaccharide (endotoxin) levels were examined on 24 occasions from 0 h before infection to 336 h after infection using the Limulus Amoebocyte Lysate chromogenic end point assay and compared with that of six (6) uninfected control animals. Peak lipopolysaccharide levels in infected animals were reached at 52 h after infection and returned to pre-infection levels at time 144 h after infection. Infected animals had significantly elevated lipopolysaccharide levels between 24 and 120 h after infection when compared to uninfected animals. The mean change in endotoxin units (EU)/mL over time after infection was statistically significant in infected animals. Elevations of lipopolysaccharide occurred in all infected animals suggesting a possible repeatable and titratable endotoxemia conducive to therapeutic agent model development.

Abstract
AT outcomes research is the systematic investigation of changes produced by AT in the lives of AT users and their environments. In contrast to focal outcome measures, My Assistive Technology Outcomes Framework (MyATOF) envisions an alternative starting point, co-designing a holistic and evidence-based set of outcome dimensions enabling AT users to quantify their own outcomes. International classification systems, research evidence, regulatory and service delivery frameworks underpin six optional tools: supports, outcomes, costs, rights, service delivery pathway and customer experience. Designed to empower the consumer-as-researcher and self-advocate, MyATOF has the potential to fill an identified gap in policy-relevant, consumer-focussed and consumer-directed outcome measurement in Australia and internationally. This paper presents the need for consumer-focussed measurement and articulates the conceptual foundations of MyATOF. The iterative development and results of MyATOF use-cases collected to date are presented. The paper concludes with next steps in using the Framework internationally, as well as its future development.

Abstract
BACKGROUND School-based youth mental health promotion is increasingly recognised as a useful tool to improve mental health knowledge and help-seeking among adolescents. Peer-led initiatives are emerging as a potentially viable mode of delivering this material. Yet, there is limited evidence on the effectiveness of these initiatives compared to more traditional, adult-led, forms of mental health promotion. AIMS This study aimed to compare improvements in students' mental health knowledge and help-seeking after attending either a peer- or adult-led youth mental health promotion workshop. It also sought to examine differential effects by gender. METHOD A within- and between-group comparative design was used to examine secondary school students' (N = 536) mental health knowledge and help-seeking intentions before and after attending a school-based mental health promotion workshop. RESULTS Students' mental health knowledge and help-seeking intentions significantly improved in both peer- and adult-led groups. Outcomes did not differ across modes of delivery, although the impact of adult-led workshops on mental health knowledge was moderated by gender. CONCLUSIONS Peer-led youth mental health promotion appears to be as effective as traditional adult-led delivery, and seems to be particularly beneficial for male students who respond more favourably to content communicated through their peers.

Abstract
Abstract
Background
The Older Persons Rehab at Home (OPRAH) team is a novel service developed to provide patients with intensive domiciliary based therapy to regain function, mobility and social care goals. This provides rehabilitation in the patients’ own home and accelerates discharge from the acute care sector. In this study patient and carer experiences of the service were explored.
Methods
Patients were sent a postal questionnaire after discharge from the service to collect information on the patient experience of the OPRAH service. The following measures were collected: satisfaction with the service, experience of interacting with therapy staff, involvement in shared goal setting and achievement of rehabilitation goals. Data from participants who responded to feedback questionnaires from the first 12 months of the service were analysed using descriptive statistics.
Results
Ninety-five participants were sent feedback questionnaires with 31 responses received (33%). 96% of participants reported that they were satisfied with the service, with the same proportion expressing that they both felt they were treated with respect and dignity and that they had confidence and trust in the staff. All respondents felt that they could understand the answers to any questions they had while receiving rehabilitation and 92% of participants understood their rehabilitation goals, with 88% of participants feeling they achieved their rehabilitation goals. 88% of participants felt they were adequately involved in their care planning with 83% of participants feeling their family members had ample opportunity to ask questions during their rehabilitation experience. Results did not different by age group of patient or by time with the service.
Conclusion
In this structured evaluation of the OPRAH team participants highly rated the service. Our results highlight that this integrated approach to care allowed patients to be involved in shared goal setting with the majority of patients satisfied that they achieved their goals.

Abstract
Abstract
Background
Older adults have longer hospital stays, higher incidence of nosocomial complications and higher readmissions rates. Older persons rehabilitation at home (OPRaH) is a novel service developed to provide patients with intensive domiciliary based therapy to regain function, mobility and social care goals. OPRaH offers a comprehensive geriatric and interdisciplinary approach. The model enables a safe and accelerated discharge from acute care to home.
Methods
Patients are identified and screened by a team coordinator. On Discharge to OPRaH the following measures were collected; basic demographics, referral source, clinical frailty score and Functional Independence Measures (FIM). Outcomes evaluated are the FIM change, readmission rates, length of inpatient stay savings and time on the service. Data from the first year of operation was analysed using descriptive statistics.
Results
109 patients have undergone rehabilitation with the service with a median age of 82 years (63-103 range). Over two thirds (68%) were classified as frail, with 44% living alone. An injurious fall was the most common reason for index hospitalisation (50%). Referral source was inpatient acute medical team in 50% of cases, with 21% from acute geriatrics , 13 % ortho geriatrics, 13% surgical. Average functional independence measure scores improved from 89 to 102 (p = 0.007). There was no difference in the magnitude of improvement by frailty status (13 vs 14, p = 0.85). The average length of stay saving was 7 days per case, with a total of 757 days saved in one year. Readmission rate within 30 days was 9.3 %. Participants highly rated the service through structured evaluation.
Conclusion
This novel service provides a valuable intervention to a wide case-mix of older adults with evidence of improvements in formal markers of functional impairment after intervention. Referral was based on definable rehabilitation goals and not just on frailty status, age, or gender.

Abstract
Antimicrobial use (AMU) in the food chain is a potential driver of antimicrobial resistance. Despite Australia's strong regulation of AMU limited to veterinary prescriptions, a proportion of empirical antimicrobial treatments are administered by dairy farmers to manage common cattle health problems. This cross-sectional survey identified key influences on AMU by dairy cattle farmers within New South Wales, Australia, to detect opportunities for antimicrobial stewardship (AMS) engagement. The study identified existing relationships, resources and attitudes of the dairy farmers that could be optimised for on-farm AMS strategies. Farmers were most highly influenced by veterinary advice and clinical signs of the animal followed by the withholding period and the potential for antimicrobial resistance development. Farmers' high confidence regarding their own knowledge of antimicrobials (>90%), their high regard for veterinary advice (>90%) and high rate of veterinary health care plan use (69%) provides a strong framework to build the profile and practice of AMS on dairy farms. Positive engagement by dairy farmers (survey response of 20%), was achieved by working with the NSW Food Authority. Despite respondents reporting low reliance on formal (government and commercial) organisations for information about AMU, their engagement demonstrates an opportunity for groups with unparalleled access to dairy farmers to drive AMS. An association between frequent use of veterinary advice and respondents keeping ceftiofur on-farm requires further investigation. Quantitative and qualitative analysis of on-farm resources, decision-making, and practices is required to understand how practices relate to veterinary advice and accepted standards of appropriate AMU on dairy farms.

Abstract
AIM The COVID-19 pandemic has presented significant challenges for young people and youth mental health services. To address a gap in knowledge about the impact of the pandemic and associated restrictions on youth mental health services, this paper examined the nature of young people's engagement with Jigsaw's brief intervention service during the pandemic. METHOD Data gathered from young people engaging with Jigsaw's brief intervention service in the 12 months after the official declaration of the COVID-19 pandemic (n = 6161), and 12 months prior (n = 8665) were examined. RESULTS There were less referrals to Jigsaw during the pandemic, especially during lockdown periods, but this rebounded when public health restrictions were eased. A higher proportion of females (p < .001) and 12-17 year olds (p < .001) were referred during the pandemic period. There was an increase in the proportion of young people who presented with anxiety (p < .001) and sleep changes (p < .001). Although 12-16 year olds reported significantly higher levels of distress during the pandemic (p < .05), the effect size was small. Young people reported high levels of satisfaction with the new phone/video modes of support offered by Jigsaw, and the overall attendance rate improved during the pandemic period. CONCLUSIONS The impact of COVID-19 on young people's mental health needs to be considered as a priority. This paper is helpful for services considering the long-term mental health needs of young people, and the best way of meeting those needs.

Abstract
BACKGROUND Infectious disease has a significant impact on livestock production. Availability of alternatives to antibiotics to prevent and treat disease is required to reduce reliance on antibiotics while not impacting animal welfare. Innate immune stimulants, such as mycobacterium cell wall fractions (MCWF), are used as alternatives to antibiotics for the treatment and prevention of infectious disease in a number of species including cattle, horses and dogs. This study aimed to evaluate the safety of Amplimune®, an MCWF-based immune stimulant, for weaner Angus cattle. METHODS On day -1 and 0, sixty mixed-sex Angus weaner cattle were transported for 6 h before being inducted and housed in a large single pen, simulating feedlot induction conditions. The cattle were assigned to one of six treatment groups (n = 10 per group): 2 mL Amplimune intramuscularly (2IM); 2 mL Amplimune subcutaneously (2SC); 5 mL Amplimune intramuscularly (5IM); 5 mL Amplimune subcutaneously (5SC); 5 mL saline intramuscularly (SalIM) and 5 mL saline subcutaneously (SalSC) on day 0 following transportation. Body temperature, body weight, concentrations of circulating pro-inflammatory cytokines (TNFα, IL-1β, IL-6 and IL-12) and haematology parameters were measured at various times up to 96 h post-treatment. RESULTS No adverse effects from Amplimune treatment were observed. Amplimune induced an increase in circulating cytokine TNFα concentrations, total white blood cell count and lymphocyte counts indicative of activation of the innate immune system without causing an excessive inflammatory response. CONCLUSIONS Results confirm that Amplimune can be safely administered to beef cattle at the dose rates and via the routes of administration investigated here.

Abstract
In our efforts to identify novel small molecule inhibitors for the treatment of adrenoleukodystrophy (ALD), we conducted a high-throughput radiometric screen for inhibitors of elongation of very long chain fatty acid 1 (ELOVL1) enzyme. We developed a series of highly potent, central nervous system (CNS)-penetrant pyrimidine ether-based compounds with favorable pharmacokinetics culminating in compound 22. Compound 22 is a selective inhibitor of ELOVL1, reducing C26:0 VLCFA synthesis in ALD patient fibroblasts and lymphocytes in vitro. Compound 22 reduced C26:0 lysophosphatidyl choline (LPC), a subtype of VLCFA, in the blood of ATP binding cassette transporter D1 (ABCD1) KO mice, a murine model of ALD to near wild-type levels. Compound 22 is a low-molecular-weight, potent ELOVL1 inhibitor that may serve as a useful tool for exploring therapeutic approaches to the treatment of ALD.

Abstract
AIMS To externally validate a proposed biochemical definition of cure following low dose rate (LDR) brachytherapy for prostate cancer - 4-year post-implant prostate-specific antigen (PSA) ≤0.2 ng/ml - in a UK population, and report the long-term (10- and 15-year) outcomes for patients stratified by National Comprehensive Cancer Network (NCCN) risk groups, through analysis of a large, prospectively collected, single-centre database. MATERIALS AND METHODS All patients treated with LDR brachytherapy for prostate cancer at a single UK centre between 2001 and November 2020 (n = 1142) were eligible; 632 patients met the inclusion criteria for the analysis. The primary end point was disease-free survival (DFS), defined as freedom from clinical, radiological or PSA progression requiring androgen deprivation therapy. Four-year PSA was categorised as ≤0.2, >0.2 to ≤0.5, >0.5 to ≤1.0 and >1.0 ng/ml. Kaplan-Meier analysis to 15 years was undertaken for each group, and sensitivity and specificity of 4-year PSA as a surrogate for long-term cure were calculated. Kaplan-Meier analysis to 15 years was repeated, stratifying patients by NCCN risk groups. RESULTS The median cohort age was 63 years; the median follow-up was 9.1 years (range 3.5-18.7). In total, 248 patients were available for analysis at year 10, 46 at year 15. Sixty-four patients (10.1%) relapsed during the study period. The 10-year DFS for 4-year PSA categories ≤0.2, >0.2 to ≤0.5, >0.5 to ≤1.0 and >1.0 ng/ml (95% confidence intervals) were 97.5% (95.4-99.6), 89.0% (82.4-96.1), 81.5% (70.5-94.2) and 41.8% (29.7-58.9), respectively. The 10-year DFS results for NCCN low, favourable-intermediate and unfavourable-intermediate risk disease were 93.1% (89.6-96.7), 92.1% (87.6-96.9) and 75.9% (67.8-84.9), respectively. CONCLUSIONS Patients with 4-year PSA ≤0.2 ng/ml may be considered cured, and could be discharged to general practitioner follow-up. LDR brachytherapy is an excellent treatment option for patients with low and favourable-intermediate risk prostate cancer, but those with unfavourable-intermediate risk disease should be considered for treatment intensification strategies.

Abstract
BACKGROUND Corticosteroid injections are used in the treatment of hand and wrist conditions. The co-administration of a local anaesthetic and corticosteroid aims to reduce pain after the injection, although no studies have directly compared this with using corticosteroid alone. The aim is to determine whether pain experienced during the 24 h after a corticosteroid injection to the hand and wrist is no worse than (not inferior to) the pain experienced after a corticosteroid and local anaesthetic injection. METHODS A single-site, patient- and assessor-blinded, non-inferiority randomised control trial recording pain visual analogue scale (VAS) scores in patients with a clinical diagnosis of trigger finger, de Quervains tenosynovitis or carpal tunnel syndrome, treated with a 1-ml triamcinolone (40 mg/1 ml) injection co-administered with or without 1 ml of 1% lidocaine. The primary aim is to investigate a difference in pain VAS scores at 1 h after the injection using a mean change score. A 95% power calculation was made using a minimally clinical important difference of 20 mm as the clinically admissible margin of non-inferiority and an assumed standard deviation of 25 mm, from previous studies. Including a 20% fall out rate, 100 patients are required. DISCUSSION Patients with a clinical diagnosis of trigger finger, de Quervains and carpal tunnel syndrome, are over the age 18 years old and who are able to give written informed consent will be included. Patients will be excluded if they have had previous surgery or corticosteroid injection for the condition being treated at the site considered for injection. Patients will be electronically randomised and injections delivered during their clinic appointment. Pain is assessed using a 100-mm VAS score taken, before and at the time of injection and at 5 min, 1 h, 2 h, 3 h and 24 h after the injection. The secondary outcomes are to determine a difference in pain VAS score at the time of injection and during the 24 h after. TRIAL REGISTRATION This study is registered on the IRAS (259336) on November 11, 2019, and EudraCT database on October 31, 2019 (2019-003742-32). REC/HRA approval was given in January 2020, and Clinical Trial Authorisation from the MHRA was given in December 2019. The study is registered on ClinicalTrials.gov ( NCT04253457 ) on February 5, 2020.

Abstract
OBJECTIVES In March 2020, the World Health Organization (WHO) officially declared the spread of coronavirus disease 2019 (COVID-19) as a pandemic. Adolescence and early adulthood are peak times for the onset of mental health difficulties. Exposure to a pandemic during this vulnerable developmental period places young people at significant risk of negative psychological experiences. The objective of this research was to summarise existing evidence on the potential impact of a pandemic on the mental health of 12-25 year olds. METHODS A rapid review of the published peer-reviewed literature, published between 1985 and 2020, using PsycINFO (Proquest) and Medline (Proquest) was conducted. Narrative synthesis was used across studies to identify key themes and concepts. RESULTS This review found 3,359 papers, which was reduced to 12 papers for data extraction. Results regarding the prevalence of psychological difficulties in youth were mixed, with some studies finding this group experience heightened distress during an infectious disease outbreak, and others finding no age differences or higher distress among adults. Gender, coping, self-reported physical health and adoption of precautionary measures appear to play a role in moderating the psychological impact of an infectious disease outbreak. Most studies were conducted after the peak of an epidemic/pandemic or in the recovery period. CONCLUSIONS More longitudinal research with young people, particularly adolescents in the general population, before and during the early stages of an infectious disease outbreak is needed to obtain a clear understanding of how best to support young people during these events.

Abstract
Patient 'engagement' or 'involvement' in health research broadly refers to including people with lived experience (i.e. individuals with personal experience of a health issue and their friends, family and caregivers or carers) in the research process. Although previous reviews have systematically summarized approaches to patient engagement in research, it is unclear whether and how engagement activities have been implemented or adapted for research related to dementia. We conducted a scoping review to describe the extent and nature of patient engagement approaches that have been used to involve persons with dementia and their care partners in research. We then summarized the reported barriers, enablers, and impacts of this engagement. Fifty-four research articles were included in the review and almost all were published after 2010. Persons with dementia and their care partners have been engaged in diverse phases of the research process. The majority of engagement involved both persons with dementia and care partners. Barriers and enablers to engagement included those identified for general patient engagement in research, but some more specific to engaging persons with dementia and their care partners were also reported. Very few studies assessed the impact of patient engagement. While the arguments for patient engagement in research are compelling, research to demonstrate the impact - on the research process and outcomes as well as on persons with dementia, care partners, researchers, research institutions and society - is still needed.

Abstract
We introduce an implantable intracardiac soft robotic right ventricular ejection device (RVED) for dynamic approximation of the right ventricular (RV) free wall and the interventricular septum (IVS) in synchrony with the cardiac cycle to augment blood ejection in right heart failure (RHF). The RVED is designed for safe and effective intracardiac operation and consists of an anchoring system deployed across the IVS, an RV free wall anchor, and a pneumatic artificial muscle linear actuator that spans the RV chamber between the two anchors. Using a ventricular simulator and a custom controller, we characterized ventricular volume ejection, linear approximation against different loads and the effect of varying device actuation periods on volume ejection. The RVED was then tested in vivo in adult pigs (n = 5). First, we successfully deployed the device into the beating heart under 3D echocardiography guidance (n = 4). Next, we performed a feasibility study to evaluate the device's ability to augment RV ejection in an experimental model of RHF (n = 1). RVED actuation augmented RV ejection during RHF; while further chronic animal studies will provide details about the efficacy of this support device. These results demonstrate successful design and implementation of the RVED and its deployment into the beating heart. This soft robotic ejection device has potential to serve as a rapidly deployable system for mechanical circulatory assistance in RHF.

Abstract
Soil microorganisms are key contributors to nutrient cycling and are essential for the maintenance of healthy soils and sustainable agriculture. Although the antimicrobial effects of a broad range of nanoparticulate substances have been characterised in vitro, little is known about the impact of these compounds on microbial communities in environments such as soil. In this study, the effect of three widely used nanoparticulates (silver, silicon dioxide and aluminium oxide) on bacterial and fungal communities in an agricultural pastureland soil was examined in a microcosm-based experiment using a combination of enzyme analysis, molecular fingerprinting and amplicon sequencing. A relatively low concentration of silver nanoparticles (AgNPs) significantly reduced total soil dehydrogenase and urease activity, while Al2O3 and SiO2 nanoparticles had no effect. Amplicon sequencing revealed substantial shifts in bacterial community composition in soils amended with AgNPs, with significant decreases in the relative abundance of Acidobacteria and Verrucomicrobia and an increase in Proteobacteria. In particular, the relative abundance of the Proteobacterial genus Dyella significantly increased in AgNP amended soil. The effects of Al2O3 and SiO2 NPs on bacterial community composition were less pronounced. AgNPs significantly reduced bacterial and archaeal amoA gene abundance in soil, with the archaea more susceptible than bacteria. AgNPs also significantly impacted soil fungal community structure, while Al2O3 and SiO2 NPs had no effect. Several fungal ribotypes increased in soil amended with AgNPs, compared to control soil. This study highlights the need to consider the effects of individual nanoparticles on soil microbial communities when assessing their environmental impact.

Abstract
AIM An understanding of effective foodservice interventions on nutrition outcomes in adult patients with cancer is required to support clinical decision making. This systematic review aimed to determine the effect of foodservice interventions across a range of nutritional outcomes and satisfaction of hospitalised and ambulatory adult oncology patients. METHODS The review protocol was registered with PROSPERO (CRD42016045772). Six databases were searched using search terms associated with the intervention and population. No date or language restrictions were applied. Authors applied the inclusion criteria to titles and abstracts and then full-text papers. The final library was assessed for risk of bias. Outcome data were combined narratively and, where possible, by meta-analysis. RESULTS From the title and abstract review of 4414 studies, 12 studies testing the effect of foodservice interventions were included in this review. Meta-analyses demonstrated significantly greater energy (mean difference 1.54 MJ/day; 95% CI 0.85-2.23 MJ/day) and protein (mean difference 18.98 g/day; 95% CI 11.58-26.39 g/day) intake through the addition of oral nutrition supplements. Other positive effects on anthropometric outcomes were also recorded. Patient satisfaction was enhanced through other foodservice interventions. CONCLUSIONS Limited original research was found exploring the effect of foodservice interventions in oncology patients. Significant findings were found in favour of the intervention across a range of nutritional outcomes, suggesting that foodservice interventions may improve clinical outcomes and satisfaction in this population. Effective foodservice interventions for oncology patients remain under-researched, so we encourage dietitians and foodservice staff to implement rigorous study designs to evaluate and publish interventions in this clinical group.

Abstract
UNLABELLED Environmental contamination by polycyclic aromatic hydrocarbons (PAHs) typically occurs as mixtures of compounds. In this study, the response of indigenous soil bacterial and fungal communities to mixtures containing phenanthrene, fluoranthene and benzo(a)pyrene in various combinations was examined using molecular fingerprinting techniques and quantification of a key PAH degradative gene. Results were compared to a parallel study by Sawulski et al. (2014) which examined the effect of these PAHs on soil microbial communities when added as single contaminants. The rate of degradation of individual PAHs varied depending on whether the PAH was present as a single contaminant or in a mixture; phenanthrene was degraded most rapidly when present as a sole contaminant, fluoranthene was removed faster in the presence of the lower molecular weight phenanthrene and the rate of benzo(a)pyrene degradation was reduced in the presence of the 4-ring PAH, fluoranthene. Bacterial and fungal assemblages differed significantly between treatments regardless of which PAH was added to soil. Although less abundant than the Gram-negative PAH-RHDα gene, the gene associated with Gram-positive bacteria responded to a greater extent to the presence of PAHs, either as single compounds or as mixtures and this increase was significantly correlated with PAH degradation. SIGNIFICANCE AND IMPACT OF THE STUDY Contaminated sites generally contain complex mixtures of pollutants. Development of effective bioremediation strategies for contaminated soils requires knowledge of the response of soil microbial communities to such mixtures. This study provides information on the degradation of different mixtures of three priority pollutants in soil with a history of polycyclic aromatic hydrocarbon contamination and examines the response of soil bacterial and fungal communities to the presence of these pollutants as sole contaminants or as part of a mixture. This is one of few studies to-date to compare the effects of single compounds and pollutant mixtures on more than one soil microbial community.

Abstract
Mouse models of systemic anaphylaxis are important tools for the study of mast cell function, for the elucidation of the pathomechanisms of anaphylaxis, and for identifying and characterizing potential therapies for anaphylaxis. Here, we describe two murine models of systemic anaphylaxis that have been a key part of research in these areas. In a passive model, mice are sensitized with antigen-specific IgE antibody 24 h prior to antigen challenge. In an active model, mice are instead sensitized with antigen 18-21 days prior to challenge. Hypothermia serves as the primary quantifiable indicator of anaphylaxis in these models.

Abstract
AIMS Anaerobic rumen fungi (Neocallimastigales) play important roles in the breakdown of complex, cellulose-rich material. Subsequent decomposition products are utilized by other microbes, including methanogens. The aim of this study was to determine the effects of dietary changes on anaerobic rumen fungi diversity. METHODS AND RESULTS Altered diets through increasing concentrate/forage (50 : 50 vs 90 : 10) ratios and/or the addition of 6% soya oil were offered to steers and the Neocallimastigales community was assessed by PCR-based fingerprinting with specific primers within the barcode region. Both a decrease in fibre content and the addition of 6% soya oil affected Neocallimastigales diversity within solid and liquid rumen phases. The addition of 6% soya oil decreased species richness. Assemblages were strongly affected by the addition of 6% soya oil, whereas unexpectedly, the fibre decrease had less effect. Differences in volatile fatty acid contents (acetate, propionate and butyrate) were significantly associated with changes in Neocallimastigales assemblages between the treatments. CONCLUSIONS Diet clearly influences Neocallimastigales assemblages. The data are interpreted in terms of interactions with other microbial groups involved in fermentation processes within the rumen. SIGNIFICANCE AND IMPACT OF THE STUDY Knowledge on the influence of diet on anaerobic fungi is necessary to understand changes in microbial processes occurring within the rumen as this may impact on other rumen processes such as methane production.

Abstract
The probability of homes in Ireland having high indoor radon concentrations is estimated on the basis of known in-house radon measurements averaged over 10 km × 10 km grid squares. The scope for using airborne gamma-ray spectrometer data for the Tralee-Castleisland area of county Kerry and county Cavan to predict the radon potential (RP) in two distinct areas of Ireland is evaluated in this study. Airborne data are compared statistically with in-house radon measurements in conjunction with geological and ground permeability data to establish linear regression models and produce radon potential maps. The best agreement between the percentage of dwellings exceeding the reference level (RL) for radon concentrations in Ireland (% > RL), estimated from indoor radon data, and modelled RP in the Tralee-Castleisland area is produced using models based on airborne gamma-ray spectrometry equivalent uranium (eU) and ground permeability data. Good agreement was obtained between the % > RL from indoor radon data and RP estimated from eU data in the Cavan area using terrain specific models. In both areas, RP maps derived from eU data are spatially more detailed than the published 10 km grid map. The results show the potential for using airborne radiometric data for producing RP maps.

Abstract
BACKGROUND Sedating and non-sedating histamine H(1) receptor (H1R) antagonists and H2R blockers are widely used drugs which are generally considered to be safe medications. However, recently, these drugs have been shown to possibly impair the outcome of perforating appendicitis in children. OBJECTIVE It was the aim of this study to characterize the effects of histamine receptor blockade in severe bacterial infections in more detail. METHODS To obtain information on the safety of histamine receptor blockade in more detail, we used pharmacological and genetic approaches targeting histamine receptors and performed cecal ligation and puncture (CLP), a mouse model of septic peritonitis. After induction of septic peritonitis, morbidity and mortality were monitored closely. RESULTS Here, we show that oral treatment with first-generation H1R antihistamine diphenhydramine, H2R blocker cimetidine and H3/4R blocker thioperamide impairs optimal innate immune responses in severe murine bacterial sepsis. However, these adverse effects are not mediated by H1R, as mice deficient for H1R show similar rates of morbidity and mortality after CLP as their wild-type controls. Similarly, the second-generation antihistamine desloratadine neither affects morbidity nor mortality after CLP. CONCLUSION Our findings indicate that sedating first-generation H1R antihistamines and H2R blockers might impair innate immune responses to bacteria and that these drugs should be used with caution in patients with severe bacterial infections.

Abstract
AIMS To examine the effect of the pollutant 2,4-dichlorophenol on DNA- and RNA-based bacterial communities in soil. METHODS AND RESULTS Soil was exposed to 100 mg kg(-1) of 2,4-dichlorophenol (2,4-DCP), and degradation was monitored over 35 days. DNA and RNA were coextracted, and terminal restriction fragment length polymorphism (T-RFLP) was used to report changes in bacterial communities in response to the presence of the chlorophenol. The phylogenetic composition of the soil during degradation was determined by creating a clone library of amplified 16S rRNA sequences from both DNA and reverse-transcribed RNA from exposed soil. Resulting clones were sequenced, and putative identities were assigned. CONCLUSIONS A significant difference between active (RNA-based) and total (DNA-based) bacterial community structure was observed for both T-RFLP and phylogenetic analyses in response to 2,4-DCP, with more pronounced changes seen in RNA-based communities. Phylogenetic analysis indicated the dominance of Proteobacteria in both profiles. SIGNIFICANCE AND IMPACT OF THE STUDY This study describes the response of soil bacterial communities to the addition of the xenobiotic compound 2,4-DCP, and highlights the importance of including RNA-based 16S rRNA analysis to complement any molecular study in a perturbed soil.

Abstract
Aromatic amines and heterocyclic amines are widely used ingredients in permanent hair dyes. However, little has been published on their potential for oxidation via hepatic cytochrome P450s. Therefore, the authors screened nine such compounds for their potential to undergo oxidative metabolism in human liver microsomes. Toluene-2,5-diamine (TDA), p-aminophenol, m-aminophenol, p-methylaminophenol, N,N'-bis(2-hydroxyethyl)-p-phenylenediamine, and 1-hydroxyethyl-4,5-diaminopyrazole showed no evidence of oxidative metabolism. Oxidized metabolites of 4-amino-2-hydroxytoluene (AHT), 2-methyl-5- hydroxyethylaminophenol (MHEAP), and phenyl methyl pyrazolone (PMP) were detected, but there was no evidence of beta-nicotinamide adenine dinucleotide phosphate (NADPH)-dependent covalent binding to microsomal protein, suggesting that these are not reactive metabolites. Metabolism of AHT, MHEAP, PMP, and TDA was further studied in human hepatocytes. All these compounds underwent conjugation, but no oxidative metabolites were found. The results suggest that none of the hair dye ingredients tested showed evidence of hepatic metabolism to potentially biologically reactive oxidized metabolites.

Abstract
PURPOSE To determine the visual and angiographic outcomes of patients with small predominantly classic choroidal neovascular membranes (CNV) undergoing photodynamic therapy (PDT). METHODS The subjects were a cohort of patients with age-related predominantly classic CNV with lesion size of greatest linear diameter of 2000 microm or less treated with PDT. Lesion size and visual acuity were recorded at baseline and at 3-month intervals. Visual treatment failure was defined as either loss of at least 15 letters or visual acuity less than 35 letters on a modified Early Treatment Diabetic Retinopathy Study chart. Lesion treatment failure was defined as increase in greatest linear diameter (GLD) of at least 500 microm. RESULTS Twenty-five eyes of 25 patients were included. Visual treatment failure occurred in 16 and mean visual acuity dropped from 58 letters to 34 letters (p<0.0001). In 11 of these patients this occurred within the first 3 months. Lesion treatment failure occurred in 18 patients. Mean GLD increased from 1331 to 2935 microm (p<0.0001). Early growth of the lesion was associated with poor visual outcome with growth in GLD in the first 3 months of 310 microm in patients without eventual visual treatment failure and 1131 microm in patients with eventual visual failure (p=0.027). CONCLUSIONS Small predominantly classic lesions commonly cause visual deterioration if treated with PDT alone. In the first year over 50% may lose at least 15 letters or drop below 35 letters, with most visual loss occurring in the first 3 months. Visual loss is associated with early lesion growth.

Abstract
Gastric adenocarcinoma (GA) is a significant cause of mortality worldwide. The molecular mechanisms of GA remain poorly characterised. Our aim was to characterise the functional activity of the computationally identified genes, NET 1 and MYEOV in GA. Digital Differential Display was used to identify genes altered expression in GA-derived EST libraries. mRNA levels of a subset of genes were quantitated by qPCR in a panel of cell lines and tumour tissue. The effect of pro- and anti-inflammatory stimuli on gene expression was investigated. Cell proliferation and invasion were measured using in an in-vitro GA model following inhibition of expression using siRNA. In all, 23 genes not previously reported in association with GA were identified. Two genes, Net1 and Myeov, were selected for further analysis and increased expression was detected in GA tissue compared to paired normal tissue using quantitative PCR. siRNA-mediated downregulation of Net1 and Myeov resulted in decreased proliferation and invasion of gastric cancer cells in vitro. These functional studies highlight a putative role for NET1 and Myeov in the development and progression of gastric cancer. These genes may provide important targets for intervention in GA, evidenced by their role in promoting invasion and proliferation, key phenotypic hallmarks of cancer cells.

Abstract
PURPOSE To determine factors associated with anatomical and functional outcomes of macula-off retinal detachment surgery in a modern vitreoretinal unit. METHODS A retrospective casenote review of 185 patients presenting with macula-off retinal detachment was performed. Demographic and ocular characteristics were determined. Logistic regression analysis was used to determine (1) the effect of these factors on visual outcome and (2) their effect on primary and final anatomical success. RESULTS Primary and ultimate anatomical success were achieved in 76 and 84% of cases. Patients with oil in at final follow-up were considered to be anatomical failures. Statistically significant factors predicting primary anatomical success using a multiple variable model were preoperative logMAR visual acuity, preoperative PVR and number of breaks. Preop logMAR visual acuity and duration of macular detachment were the statistically significant factors predicting ultimate success. In all, 44% of patients regained 6/12 Snellen or better with a median improvement of 0.78 logMAR. For prediction of visual outcome (in patients with no ocular comorbidity) only preoperative logMAR visual acuity achieved statistical significance (P=0.001) at the P=0.05 level. CONCLUSION In all, 76% of macula-off detachments may be repaired with one operation and 44% of patients regain at least 6/12 Snellen. The median logMAR acuity increment of 0.78 far exceeds that seen in cataract surgery. Preoperative visual acuity is the most important factor predicting primary and final anatomical success as well as visual outcome. Preoperative PVR, number of breaks and duration of detachment also affect outcomes.

Abstract
AIMS To report two cases of allergic reaction to upper lid gold weight implants in patients with facial nerve palsy and to identify the use of pre-implantation patch testing in predicting gold hypersensitivity. METHODS One patient who had a positive family history of gold allergy and had undergone previous gold dental restoration underwent patch testing with gold sodium thiosulphate. The gold weight from the same patient was analysed using scanning electron microscopy and energy dispersive X-ray analysis, which can detect surface impurities. Tissue obtained during surgery to remove the gold weight from the second patient was examined histologically. RESULTS Patch testing in the first patient gave a positive result. Analysis of the gold weight removed from the same patient confirmed 99.99% purity, and hence sensitivity to the gold itself was considered to be the cause of the inflammatory reaction. Histology of tissue taken from the eyelid of the second patient was consistent with type IV hypersensitivity. CONCLUSION A personal and family history of gold allergy should be looked for before upper eyelid gold weight implantation. Patch testing should be performed for patients where there is doubt about whether gold has been the specific cause of previous allergic reactions, for patients who have undergone previous dental restoration involving gold, or if there is a positive family history of gold allergy.
