Abstract
Background: For evidence-based medical practice, well-defined risk scoring systems are essential to identify patients with a poor prognosis. The objective of this study was to develop a prognostic score, the Montreal prognostic score (MPS), to improve prognostication of patients with incurable non-small cell lung cancer (NSCLC) in everyday practice. Methods: A training cohort (TC) and a confirmatory cohort (CC) of newly diagnosed patients with NSCLC planning to receive chemotherapy were used to develop the MPS. Stage and clinically available biomarkers were entered into a Cox model and risk weights were estimated. C-statistics were used to test the accuracy. Results: The TC consisted of 258 patients and the CC consisted of 433 patients. Montreal prognostic score classified patients into three distinct groups with median survivals of 2.5 months (95% confidence interval (CI): 1.8, 4.2), 8.2 months (95% CI: 7.0, 9.4) and 18.2 months (95% CI: 14.0, 27.5), respectively (log-rank, P<0.001). Overall, the C-statistics were 0.691 (95% CI: 0.685, 0.697) for the TC and 0.665 (95% CI: 0.661, 0.670) for the CC. Conclusion: The MPS, by classifying patients into three well-defined prognostic groups, provides valuable information, which physicians could use to better inform their patients about treatment options, especially the best timing to involve palliative care teams.

Abstract
The Schizophrenia Psychiatric Genome-Wide Association Study Consortium (PGC) highlighted 81 single-nucleotide polymorphisms (SNPs) with moderate evidence for association to schizophrenia. After follow-up in independent samples, seven loci attained genome-wide significance (GWS), but multi-locus tests suggested some SNPs that did not do so represented true associations. We tested 78 of the 81 SNPs in 2640 individuals with a clinical diagnosis of schizophrenia attending a clozapine clinic (CLOZUK), 2504 cases with a research diagnosis of bipolar disorder, and 2878 controls. In CLOZUK, we obtained significant replication to the PGC-associated allele for no fewer than 37 (47%) of the SNPs, including many prior GWS major histocompatibility complex (MHC) SNPs as well as 3/6 non-MHC SNPs for which we had data that were reported as GWS by the PGC. After combining the new schizophrenia data with those of the PGC, variants at three loci (ITIH3/4, CACNA1C and SDCCAG8) that had not previously been GWS in schizophrenia attained that level of support. In bipolar disorder, we also obtained significant evidence for association for 21% of the alleles that had been associated with schizophrenia in the PGC. Our study independently confirms association to three loci previously reported to be GWS in schizophrenia, and identifies the first GWS evidence in schizophrenia for a further three loci. Given the number of independent replications and the power of our sample, we estimate 98% (confidence interval (CI) 78-100%) of the original set of 78 SNPs represent true associations. We also provide strong evidence for overlap in genetic risk between schizophrenia and bipolar disorder.

Abstract
AIMS The association between obesity and a poorer health-related quality of life (HRQL) has previously been explored. The influence of ethnicity on this relationship has less frequently been considered. We aimed to explore the relationship between body mass index (BMI) and HRQL in a mixed population of White European (WE) and South Asian (SA) ethnicity. METHODS Cross-sectional data were analysed (n = 4989, 16% SA) from a population-based diabetes screening study. BMI categories were based on ethnic-specific cut-points. HRQL was categorized low (<0.848) or high (≥0.848) according to the median EQ5D score. Logistic regression was used to examine the relationship between BMI and HRQL. Interaction analysis was conducted to determine the effect of ethnicity. RESULTS Overweight (OR = 1.22, 95% CI: 1.10-1.41, p < 0.001) and obese people (OR = 1.81, 95% CI: 1.56-2.10, p < 0.001) had increased odds of having a low HRQL compared to normal weight people. After adjusting for potential confounders, age, gender, ethnicity, deprivation score, fruit and vegetable intake, physical activity, cardiovascular disease, chronic kidney disease and smoking, this association was strengthened further. However, for obese people, SA ethnicity significantly reduced the risk of having a low HRQL when compared to WEs (adjusted OR = 0.58, 95% CI: 0.34-0.97). CONCLUSIONS Our findings provide further evidence of an association between increasing BMI and low HRQL but suggest that SA ethnicity modifies this relationship. These results could have important health implications and are a basis for further research.

Abstract
Foodborne pathogens can attach to, and survive on, food contact surfaces for long periods by forming a biofilm. Salmonella enterica is the second most common cause of foodborne illness in Ireland. The ability of S. enterica to form a biofilm could contribute to its persistence in food production areas, leading to cross-contamination of products and surfaces. Arising from a large foodborne outbreak of S. enterica serovar Agona associated with a food manufacturing environment, a hypothesis was formulated that the associated Salmonella Agona strain had an enhanced ability to form a biofilm relative to other S. enterica. To investigate this hypothesis, 12 strains of S. enterica, encompassing three S. enterica serovars, were assessed for the ability to form a biofilm on multiple food contact surfaces. All isolates formed a biofilm on the contact surfaces, and there was no consistent trend for the Salmonella Agona outbreak strain to produce a denser biofilm compared with other strains of Salmonella Agona or Salmonella Typhimurium. However, Salmonella Enteritidis biofilm was considerably less dense than Salmonella Typhimurium and Salmonella Agona biofilms. Biofilm density was greater on tile than on concrete, polycarbonate, stainless steel, or glass.

Abstract
There is a concern that hospital effluent potentially containing antimicrobial compounds, antimicrobial resistant (AMR) bacteria and genetic determinants of resistance may contribute to the emergence, dissemination and persistence of AMR bacteria in municipal wastewaters. Hence, it is of interest to investigate the effect, if any, hospital effluent has on the percentage of AMR bacteria within wastewater. Water from two wastewater treatment plants (WWTPs) (one receives and treats hospital effluent (WWTPhe) and the second does not (WWTPc)) were examined for E. coli expressing resistance to seven antimicrobials (ampicillin, streptomycin, cefoxitin, cefotaxime, tetracycline, sulphonamide and ciprofloxacin). A two-sample t-test showed that AMR E. coli are present in WWTP influent and effluent, irrespective of receiving hospital effluent, and are being released into the environment (no statistical difference in count between the two WWTPs). The effect of hospital effluent on resistance varies for each AMR bacteria. Excluding tetracycline, sulphonamide and ciprofloxacin, the results suggest that the release of hospital effluent does not significantly affect the frequency with which AMR E. coli are detected in effluent. For some hospital specific antimicrobial agents, such as ciprofloxacin, the release of hospital effluent is associated with an increased proportion of antimicrobial resistance. The results suggest resistance to AMR E. coli may already be well developed in the community, making the effect of hospital effluent on AMR E. coli indistinguishable. However, for hospital specific antimicrobials, there may be a selective effect and hence limiting the release of hospital effluent containing such antimicrobials may impact the proportion of antimicrobial resistance. This research has provided statistical evidence to support necessary mitigation and remediation of antimicrobial residue release and subsequent resistance in the environment.

Abstract
This review summarises updated clinical guidelines produced by the Clinical Standards Committee of the Faculty of Dental Surgery, Royal College of Surgeons of England (FDSRCS). This guideline on the management of the palatally ectopic maxillary canine illustrates the information contained in the recently updated online version. The timely recognition of ectopic canines is important for the overall management of the dentition. This review illustrates five management strategies for ectopic permanent canines: interceptive treatment by extraction of the deciduous canine, surgical exposure and orthodontic alignment, surgical removal of the palatally ectopic permanent canine, auto-transplantation and no active treatment/leave and observe. The current available evidence for each of these management options has been evaluated and awarded a grade used by the Scottish Intercollegiate Guidelines Network.

Abstract
Nursing homes are reservoirs for antimicrobial-resistant organisms (AROs). This study examined the time to environmental contamination with AROs in a new-build nursing home. Environmental sites in an occupied nursing home (N = 18) and a newly built replacement nursing home (N = 21) were monitored during an 11-week period before and after residents transferred between buildings. Meticillin-resistant Staphylococcus aureus was detected during commissioning in the new building and was a frequent finding throughout the building after residents had moved in. Extended-spectrum beta-lactamase-producing E. coli O25b:ST131 was detected once.

Abstract
Marine protected areas (MPAs) are a primary policy instrument for managing and protecting coral reefs. Successful MPAs ultimately depend on knowledge-based decision making, where scientific research is integrated into management actions. Fourteen coral reef MPA managers and sixteen academics from eleven research, state and federal government institutions each outlined at least five pertinent research needs for improving the management of MPAs situated in Australian coral reefs. From this list of 173 key questions, we asked members of each group to rank questions in order of urgency, redundancy and importance, which allowed us to explore the extent of perceptional mismatch and overlap among the two groups. Our results suggest the mismatch among MPA managers and academics is small, with no significant difference among the groups in terms of their respective research interests, or the type of questions they pose. However, managers prioritised spatial management and monitoring as research themes, whilst academics identified climate change, resilience, spatial management, fishing and connectivity as the most important topics. Ranking of the posed questions by the two groups was also similar, although managers were less confident about the achievability of the posed research questions and whether questions represented a knowledge gap. We conclude that improved collaboration and knowledge transfer among management and academic groups can be used to achieve similar objectives and enhance the knowledge-based management of MPAs.

Abstract
The epidemiology of carbapenemase-producing Enterobacteriaceae (CPE) in Ireland is changing, with an increase in the number of reported cases in late 2010 and early 2011. Reported cases were predominantly linked to critical care units. In June 2011, a four-week national pilot survey took place in 40 Irish critical care units (37 adult and three paediatric) to examine the prevalence of rectal carriage of CPE and inform national CPE screening guidelines. A total of 760 screening swabs were taken over the study period, and CPE were not detected in any of the participating critical care units.

Abstract
Sequence data from salmonid alphavirus (SAV) strains obtained from farmed marine Atlantic salmon, Salmo salar L. , over a 20-year period between 1991 and 2011 was reviewed to examine the geographical distribution of the genetically defined SAV subtypes in twelve regions across Ireland and Scotland. Of 160 different Atlantic salmon SAV strains examined, 62 belonged to subtype 1, 28 to subtype 2, 34 to subtype 4, 35 to subtype 5 and 1 to subtype 6. SAV subtypes 1, 4 and 6 were found in Ireland, while subtypes 1, 2, 4 and 5 were found in Scotland. In the majority of regions, there was a clear clustering of subtypes, with SAV subtype 1 being the dominant subtype in Ireland overall, as well as in Argyll and Bute in Scotland. SAV subtype 2 predominated in the Shetland and Orkney Islands. The emergence in Atlantic salmon of subtype 2 strains typically associated with sleeping disease in rainbow trout in Argyll and Bute, strongly suggesting transmission of infection between these species, was noted for the first time. SAV subtype 4 was the most common subtype found in the southern Western Isles, while SAV subtype 5 predominated in the northern Western Isles and north-west mainland Scotland. No single strain was dominant on sites in the western Highlands, with a number of sites in this region in particular having more than one subtype detected in different submissions. The significance of these results in relation to aspects of the epidemiology of infection, including transmission, biosecurity and wildlife reservoirs are discussed and knowledge gaps identified.

Abstract
Lung cancer is one of the most commonly diagnosed malignancies and the leading cause of cancer-related mortality in Canada. The heterogeneity of nsclc and the importance of linking new targeted agents to the appropriate disease subtype require an individualized approach to treatment. In patients with EGFR (epidermal growth factor receptor gene) mutations, EGFR tyrosine kinase inhibitors (TKIs) provide a highly effective treatment option, with improved toxicity compared with standard chemotherapy. However, the identification of mutation-positive patients is limited by a lack of funding for testing. The length of time required to receive test results and insufficient tissue from biopsies are additional limitations. In Canada, the use of EGFR-TKIs varies based on differences in provincial funding for both testing and treatment. With improvements in testing and access to funding for treatment, targeted use of EGFR-TKIs may greatly improve outcomes in NSCLC.

Abstract
Non-small-cell lung cancer (nsclc) remains the leading cause of cancer-related death globally, with most patients presenting with non-curable disease. Platinum-based doublet chemotherapy has been the cornerstone of treatment for patients with advanced-stage disease and has resulted in a modest increase in overall survival (on the order of an incremental 2 months increased survival per decade) and quality of life. Improved knowledge of the molecular signalling pathways found in nsclc has led to the development of biomarkers with associated targeted therapeutics, thus changing the treatment paradigm for many nsclc patients. In this review, we present a summary of many of the currently investigated nsclc targets, discuss their current clinical trial status, and provide commentary as to the likelihood of their success making a positive impact for nsclc patients.

Abstract
Experimental studies support a neurotrophic hypothesis of major depressive disorder (MDD). The aim of this study was to determine the effect of Val66Met brain-derived neurotrophic factor (BDNF) polymorphism on the white matter fiber tracts connecting hippocampus and amygdala with the prefrontal lobe in a sample of patients with MDD and healthy controls. Thirty-seven patients with MDD and 42 healthy volunteers were recruited. Diffusion tensor imaging (DTI) data with 61 diffusion directions were obtained with MRI 3 Tesla scanner. Deterministic tractography was applied with ExploreDTI and Val66Met BDNF SNP (rs6265) was genotyped. Fiber tracts connecting the hippocampus and amygdala with the prefrontal lobe, namely uncinate fasciculus (UF), fornix, and cingulum were analyzed. A significant interaction was found in the UF between BDNF alleles and diagnosis. Patients carrying the BDNF met-allele had smaller fractional anisotropy (FA) in the UF compared to those patients homozygous for val-allele and compared to healthy subjects carrying the met-allele. A significant three-way interaction was detected between region of the cingulum (dorsal, rostral, and parahippocampal regions), brain hemisphere and BDNF genotype. Larger FA was detectable in the left rostral cingulum for met-allele carriers when compared to val/val alelle carriers. We provide evidence for the importance of the neurotrophic involvement in limbic and prefrontal connections. The met-allele of the BDNF polymorphism seems to render subjects more vulnerable for dysfunctions associated with the UF, a tract known to be related to negative emotional-cognitive processing bias, declarative memory problems, and autonoetic self awareness.
