Abstract
BACKGROUND Sacituzumab govitecan (SG), a novel antibody-drug conjugate (ADC) targeting TROP2, is approved for pre-treated metastatic triple-negative breast cancer (mTNBC). We conducted an investigator-initiated clinical trial evaluating neoadjuvant (NA) SG (NCT04230109), and report primary results. PATIENTS AND METHODS Participants with early-stage TNBC received NA SG for four cycles. The primary objective was to assess pathological complete response (pCR) rate in breast and lymph nodes (ypT0/isN0) to SG. Secondary objectives included overall response rate (ORR), safety, event-free survival (EFS), and predictive biomarkers. A response-guided approach was utilized, and subsequent systemic therapy decisions were at the discretion of the treating physician. RESULTS From July 2020 to August 2021, 50 participants were enrolled (median age = 48.5 years; 13 clinical stage I disease, 26 stage II, 11 stage III). Forty-nine (98%) completed four cycles of SG. Overall, the pCR rate with SG alone was 30% [n = 15, 95% confidence interval (CI) 18% to 45%]. The ORR per RECIST V1.1 after SG alone was 64% (n = 32/50, 95% CI 77% to 98%). Higher Ki-67 and tumor-infiltrating lymphocytes (TILs) were predictive of pCR to SG (P = 0.007 for Ki-67 and 0.002 for TILs), while baseline TROP2 expression was not (P = 0.440). Common adverse events were nausea (82%), fatigue (76%), alopecia (76%), neutropenia (44%), and rash (48%). With a median follow-up time of 18.9 months (95% CI 16.3-21.9 months), the 2-year EFS for all participants was 95%. Among participants with a pCR with SG (n = 15), the 2-year EFS was 100%. CONCLUSIONS In the first NA trial with an ADC in localized TNBC, SG demonstrated single-agent efficacy and feasibility of response-guided escalation/de-escalation. Further research on optimal duration of SG as well as NA combination strategies, including immunotherapy, are needed.

Abstract
There are still some controversies regarding the clinical use of cementless UKAs. The aim of this systematic review was to determine whether cementless medial UKA leads to similar outcomes compared to cemented medial UKA. This search was conducted in accordance with the Preferred Reporting Items for Systematic Reviews guidelines (PRISMA). The random effects model with 95% confidence interval (CI) was applied to the analysis. The I2 statistic was used to assess study heterogeneity. Six studies were eligible for inclusion (4784 UKAs, 4776 patients): 2947 cemented UKAs (61.6%) and 1837 cementless UKAs (38.4%). The overall mean follow-up was 4.9 years. The all-cause reoperation rate was 11.3% (80 of 706) at mean 5.7-year follow-up for cemented UKA and 6.9% (57 of 824) at mean 4.1-year follow-up for the cementless. The overall revision rate was 10.2% (303 of 2947) for the cemented and 5.8% (108 of 1837) for the cementless. Aseptic loosening was the most frequent reason of revision (2.3% cemented vs 0.5% cementless). The overall rate of radiolucent lines (RLL) was 28.3% (63 of 223) in the cemented cohort and 11.1% in the cementless (26 of 234). All the studies reported improved functional outcomes. Cementless UKA provides at least equivalent if not better results compared to cemented UKA. Despite the use of cemented UKA outnumber cementless fixation, available data shows that cementless UKA had a reduced midterm revision rate, while providing similar functional outcomes.

Abstract
We hypothesized productive activities, e.g., working and volunteering, would reduce dementia risk and mitigate racial disparities using longitudinal Health, Aging, and Body Composition data (n=3,069). We ran gender-stratified logistic regression models for dementia with socio-demographic and APOE adjustments. Among older men, no significant relationships existed between dementia with work, volunteering, or race in any models. Among older women, in unadjusted models, working vs. not (Yr1) was significantly related to 30% lower odds of dementia (OR=0.70, p≤0.05), and volunteering vs. not (Yr1) was significantly related to 24% lower odds of dementia (OR=0.76, p≤0.05). But, these activities were not significant in other models. Black vs. White women had 35% (OR=1.35, p≤0.05) and 32% (OR=1.32, p=0.052) higher odds of dementia in working and volunteering models with socio-demographic adjustments, respectively, but race was not significant after APOE adjustment. Productive activities are possible contextual interventions to reduce racial disparities in incident dementia among older women.

Abstract
The COVID-19 pandemic has differentially impacted population sub-groups over the last two years. For example, engagement in social isolation may have been particularly difficult for extroverted adults. The virus spread widely in densely populated regions and is more risky to health with increasing age. This paper explores the ways in which personality, age, and urbanicity are associated with subjective well-being during the pandemic. Longitudinal data from the Health and Retirement Study (N = 4316; M age = 69.0, Range 31 - 99) investigates Big Five personality characteristics from 2016 and interactions with age on life satisfaction and loneliness during the pandemic. Models are then stratified by Beale Rural-Urban Continuum codes denoting urban, suburban, and ex-urban residence. Results indicate the benefit of high conscientiousness on life satisfaction is weaker among older adults (p<.05) and associations of extroversion and age on loneliness are driven by individuals living in urban areas (p<.05).

Abstract
Background Older adults frequently attend the Emergency Department (ED) and experience high rates of adverse outcomes following ED presentation including functional decline, ED re-presentation and unplanned hospital admission. The development of effective interventions to prevent such outcomes is a key priority for research and service provision. A presentation to an ED can be viewed as an opportunity to assess those at risk of adverse outcomes and initiate a care plan in those deemed as ‘high risk'. Our aim was to evaluate the feasibility of a physiotherapy led integrated care intervention for older adults discharged from the ED (ED-PLUS). Methods Older adults presenting to the ED with undifferentiated medical complaints and discharged within 72 hours were computer randomised in a ratio of 1:1:1 to deliver usual care, Comprehensive Geriatric Assessment (CGA) in the ED, or ED-PLUS (Trial registration: NCT04983602). ED-PLUS is an evidence-based and stakeholder-informed intervention to bridge the care transition between the ED and community by initiating a CGA in the ED and implementing a six-week, multi-component, self-management programme in the patient’s own home. Feasibility (recruitment and retention rates) and acceptability of the programme were assessed quantitatively and qualitatively. Functional decline was examined post-intervention using the Barthel Index. All outcomes were assessed by a research nurse blinded to group allocation. Results 29 participants were recruited, indicating 97% of our recruitment target. 90% of participants completed the ED-PLUS intervention. All participants expressed positive feedback about the intervention. The incidence of functional decline at 6 weeks was 10% in the ED-PLUS group versus 70-89% in the usual care and CGA-only groups. Conclusion High adherence and retention rates were observed among participants and preliminary findings indicate a lower incidence of functional decline in the ED-PLUS group. Recruitment challenges existed in the context of COVID-19. Data collection is ongoing for six-month outcomes.

Abstract
Introduction
There are an increasing number of older people live with advanced kidney disease. These individuals tend to have a higher number of co-morbidities, including frailty. This group experience multiple challenges in understanding and managing their co-existing conditions. This quality improvement project aimed to incorporate patient and carers views and experiences to improve their understanding and support self-management.
Method
Semi-structured interviews were conducted with older patients with advanced kidney disease and their carers. Interviews explored their views on ageing and frailty, how it affects them, coping strategies, resource awareness and opinions on structure and content for an educational leaflet for older people with kidney disease. The interviews were transcribed verbatim then coded into themes to inform key topics for the leaflet. These were used to generate reader-friendly questions and answers. The leaflet was reviewed and approved by the Clinical Committee and Patient Information Board in Kidney Care UK.
Results
10 individuals (8 patients and 2 carers) were interviewed. Patients were aged 62–88 years. Three were receiving haemodialysis, two peritoneal dialysis, two had a kidney transplant and three attended the advanced kidney care clinic. The five most common codes identified were ‘physical exercise’, ‘losing abilities’, ‘mobility’, ‘prevention and safety’ and ‘medical problems’. Themes identified were 1. Mood and memory, 2. Mobility and medical problems, 3. Self-help and supports, 4. Determination, 5. Impact on self and other. The leaflet title was chosen by patients and carers. Figure 1 shows the completed, published leaflet.
Conclusion
This quality improvement project used semi-structured interviews with older patients and carers affected by advanced kidney disease. The main issues they identified in relation to getting older with kidney disease were included in an educational leaflet. Partnership with Kidney Care UK has made the leaflet available across the UK. We hope it will directly address their everyday concerns.

Abstract
The current study examines the unique impacts of the ongoing COVID-19 Pandemic on the well-being of middle aged to older women from the 2020 Health and Retirement Study (n = 1252) and how their reports of social contact during the pandemic compare to age-matched women from 2018 (n = 2063). Although up to a third of women across age categories reported changes in social contact due to the pandemic, their rates of communication with friends and family were not significantly different from their counterparts in 2018. Results find expected age patterns in satisfaction with life during the pandemic), where the young-old report the highest levels. However, the association of life satisfaction with the extent to which women reported more loneliness during the pandemic was only significant among the young old and oldest old. Age differences in pandemic-specific experiences in relation to well-being are discussed within a life course developmental framework.

Abstract
The current study examines how cohort differences across two age-matched groups of midlife and older women from the Health and Retirement Study are associated with well-being and self-perceptions of aging (SPA). Women aged 51–60 (n=2318) and 61–70 (n=1650) were selected from the 2008 and 2018 waves. No significant cohort differences were identified for life satisfaction (Diener, Emmons, Larsen & Griffin, 1985) or positive SPA (Lawton, 1975; Liang & Bollen, 1983). The 2008 cohort of midlife women reported significantly higher negative SPA compared to 2018 (p<.05). Linear regression analyses find that cohort and SPA are significantly associated with life satisfaction in both age groups, and that the association of negative SPA differs by cohort for the midlife women (p<.01). Implications are discussed within the life course developmental framework.

Abstract
To identify potential factors influencing age-related cognitive decline and disease, we created MindCrowd. MindCrowd is a cross-sectional web-based assessment of simple visual (sv) reaction time (RT) and paired-associate learning (PAL). svRT and PAL results were combined with 22 survey questions. Analysis of svRT revealed education and stroke as potential modifiers of changes in processing speed and memory from younger to older ages (ntotal = 75,666, nwomen = 47,700, nmen = 27,966; ages 18-85 years old, mean (M)Age = 46.54, standard deviation (SD)Age = 18.40). To complement this work, we evaluated complex visual recognition reaction time (cvrRT) in the UK Biobank (ntotal = 158,249 nwomen = 89,333 nmen = 68,916; ages 40-70 years old, MAge = 55.81, SDAge = 7.72). Similarities between the UK Biobank and MindCrowd were assessed using a subset of MindCrowd (UKBb MindCrowd) selected to mirror the UK Biobank demographics (ntotal = 39,795, nwomen = 29,640, nmen = 10,155; ages 40-70 years old, MAge = 56.59, SDAge = 8.16). An identical linear model (LM) was used to assess both cohorts. Analyses revealed similarities between MindCrowd and the UK Biobank across most results. Divergent findings from the UK Biobank included (1) a first-degree family history of Alzheimer's disease (FHAD) was associated with longer cvrRT. (2) Men with the least education were associated with longer cvrRTs comparable to women across all educational attainment levels. Divergent findings from UKBb MindCrowd included more education being associated with shorter svRTs and a history of smoking with longer svRTs from younger to older ages.

Abstract
We conducted an empirical examination of derived relational responding as a generalized operant and concurrently evaluated the validity and efficacy of program items contained in the Promoting the Emergence of Advanced Knowledge - Equivalence (PEAK-E) curriculum. A first study utilized a multiple-baseline across-skills experimental arrangement to determine the efficacy of equivalence-based instruction guided by PEAK-E, replicated across 11 children with autism. A total of 33 individualized skills were taught, and the subsequent emergence of untrained relations was tested throughout the investigation. The mastery criterion was achieved for 29 of the 33 instructional targets. Additionally, for 3 participants, results were again replicated with a novel set of stimuli. A second study evaluated the degree to which multiple-exemplar equivalence-based instruction led to the emergence of derived relational responding as a generalized operant. The organized nature of the PEAK curriculum allowed the impact on derived relational responding to be compared to that produced by earlier PEAK models that are focused on the direct training of traditional verbal operants. PEAK-E instruction was introduced in a multiple-baseline design across two participants, with a third staying in a training baseline throughout. Increases in derived relational responding using novel, untrained stimuli were only observed when multiple-exemplar equivalence-based instruction was introduced. Taken together, these results provide support for derived relational responding as a generalized operant and demonstrate the utility of conducting larger scale evaluations of higher order behavioral phenomena in single-case experimental arrangements.

Abstract
Vascular contributions to cognitive impairment and dementia (VCID) include structural and functional blood vessel injuries linked to poor neurocognitive outcomes. Smoking might indirectly increase the likelihood of cognitive impairment by exacerbating vascular disease risks. Sex disparities in VCID have been reported, however, few studies have assessed the sex-specific relationships between smoking and memory performance and with contradictory results. We investigated the associations between sex, smoking, and cardiovascular disease with verbal learning and memory function. Using MindCrowd, an observational web-based cohort of ~ 70,000 people aged 18-85, we investigated whether sex modifies the relationship between smoking and cardiovascular disease with verbal memory performance. We found significant interactions in that smoking is associated with verbal learning performance more in women and cardiovascular disease more in men across a wide age range. These results suggest that smoking and cardiovascular disease may impact verbal learning and memory throughout adulthood differently for men and women.

Abstract
Emerging evidence of brain injury on risk of neurodegenerative diseases such as Alzheimer's disease (AD) and chronic traumatic encephalopathy (CTE) have resulted in interest in therapeutic potential of omega-3 fatty acids (n-3FA). We conducted a systematic review of n-3FA therapeutic efficacy for ageing adults at risk of AD/CTE following a history of repeated head trauma. Databases for articles between 1980-June 2020 were examined for studies reporting on n-3 FAs in adults (≥ 45 years) with a history of repeated brain injury. Following an initial screen of 175 articles, 12 studies were considered but were eventually rejected, as they did not meet inclusion criteria. Our review could find no evidence to support, or disprove, effectiveness of n-3FA intervention in older adults with a history of head trauma. With animal studies showing neuro-restorative potential of n-3FA following brain injury, this review highlights the urgent need for human research in this area.

Abstract
Cross-sectional analyses of internet use patterns among older adults find that the rate of internet use is less with greater physical and memory difficulties. It is not clear, however, how age-cohorts differ in their internet use as physical and memory difficulties increase over time. In addition to factors such as increasing accessibility (cost) and social influences, the expansion and cognitive complexity of functions performed by the internet-enabled devices over time could influence internet use patterns. In this study, we investigate how the association between internet use and episodic memory difficulties over time varies between cohorts. We analyzed longitudinal data from the Health and Retirement Study (N = 15,703 in 2002; Aged 51 and older) between years 2002-2016 using mixed effects logistic regression models. Immediate and delayed word recall measures were used to assess episodic memory. Rate of internet use in the sample increased from 30% in 2002 to 53% in 2016. Rate of internet use among younger age groups was significantly higher in the baseline year. Younger age groups also showed a significantly higher rate of increase in internet use over time. In general, internet use decreased with episodic memory impairment. In addition to these effects, the effect of episodic memory on the rate of increase in internet use over time is lower in younger cohorts. These results indicate that younger cohorts of older adults are more likely to maintain internet use as they continue to age and therefore could better utilize technology for communication, social interactions and health interventions.

Abstract
High-level resistance and treatment failures with ceftriaxone and azithromycin, the first-line agents for gonorrhoea treatment are reported and antimicrobial-resistant Neisseria gonorrhoeae is an urgent public health threat. Our aims were to determine antimicrobial resistance rates, resistance determinants and phylogeny of N. gonorrhoeae in Ireland, 2014-2016. Overall, 609 isolates from four University Hospitals were tested for susceptibility to extended-spectrum cephalosporins (ESCs) and azithromycin by the MIC Test Strips. Forty-three isolates were whole-genome sequenced based on elevated MICs. The resistance rate to ceftriaxone, cefixime, cefotaxime and azithromycin was 0, 1, 2.1 and 19%, respectively. Seven high-level azithromycin-resistant (HLAzi-R) isolates were identified, all susceptible to ceftriaxone. Mosaic penA alleles XXXIV, X and non-mosaic XIII, and G120K plus A121N/D/G (PorB1b), H105Y (MtrR) and A deletion (mtrR promoter) mutations, were associated with elevated ESC MICs. A2059G and C2611T mutations in 23S rRNA were associated with HLAzi-R and azithromycin MICs of 4-32 mg/L, respectively. The 43 whole-genome sequenced isolates belonged to 31 NG-MAST STs. All HLAzi-R isolates belonged to MLST ST1580 and some clonal clustering was observed; however, the isolates differed significantly from the published HLAzi-R isolates from the ongoing UK outbreak. There is good correlation between previously described genetic antimicrobial resistance determinants and phenotypic susceptibility categories for ESCs and azithromycin in N. gonorrhoeae. This work highlights the advantages and potential of whole-genome sequencing to be applied at scale in the surveillance of antibiotic resistant strains of N. gonorrhoeae, both locally and internationally.

Abstract
Dietary supplements are increasingly popular in Irish society. One of these is blue-green algae which is used with a variety health benefits in mind. A batch of Chlorella powder was found to be contaminated with Salmonella species in Ireland in 2015. This prompted additional testing of a total of 8 samples of three different products (Chlorella, Spirulina and Super Greens), for other faecal flora and antimicrobial resistance in any bacteria isolated. All 8 samples cultured enteric flora such as Enterococci, Enterobacteriaceae and Clostridium species. Antimicrobial susceptibility testing revealed one isolate with extended-spectrum ?-lactamase (ESBL) activity and one with carbapenemase activity. Clinicians caring for vulnerable patients should be aware of the potential risk of exposure to antimicrobial resistant bacteria associated with these products.

Abstract
The aim of this study was to compare an in-house real-time PCR assay, with bacterial culture as the reference, for the diagnosis of late onset group B Streptococcal (GBS) disease. This was a retrospective review. All children aged 7-90 days presenting to four paediatric centres that had a blood or CSF sample tested by GBS PCR were included. Of 7,686 blood and 2,495 cerebrospinal fluid (CSF) samples from patients of all ages received for PCR testing, 893 and 859 samples were eligible for the study, respectively. When compared to culture, the sensitivity of blood PCR was 65% (13/20) in comparison to the CSF PCR test which was 100% (5/5). Ten of 23 PCR-positive blood samples and 17 of 22 PCR-positive CSF samples were culture negative. The median threshold Ct values for culture-positive/PCR-positive CSF samples was lower than that of culture-negative/PCR-positive CSF samples (p = 0.08). Clinical details of 17 available cases that were culture negative/PCR positive were reviewed; seven were deemed to be definite cases, eight were probable and two were possible. The results showed that detection of GBS by PCR is useful for CSF samples from infants aged 7-90 days with suspected meningitis; however, analysis of blood samples by PCR is of limited value as a routine screening test for late onset GBS sepsis and should not replace bacterial culture.

Abstract
INTRODUCTION Land use planning is a complex field comprised of legislation, policies, processes and tools. A growing body of evidence supports the relationship between land use planning decisions, community design and health. The built environment has been shown to be associated with physical inactivity, obesity, cardiovascular disease, respiratory disease and mental illness. Consequently, there is a growing interest within public health to work with planners on land use planning initiatives such as official plans and transportation master plans. METHODS Two surveys were developed: one for public health professionals and the other for planning professionals (survey questions available upon request to the corresponding author). The surveys were pilot tested in two separate focus group sessions with public health and planning professionals. Focus group volunteers helped to validate the surveys by verifying survey questions, design and overall flow. RESULTS In early 2012, 304 public health professionals and 301 planning professionals completed the two separate surveys, comprising the total survey respondents for each respective profession used to calculate proportions. The survey results represent a convenience sample and are not generalizable to the entire population of public health and planning professionals in Ontario. Results compare survey responses from both groups where appropriate. Most respondents worked either as public health staff (78%) or planners/senior planners (58%). A smaller percentage of public health and planning professionals worked either as managers (15% and 11%, respectively) or directors (5% and 9%, respectively). CONCLUSION Health is associated with how communities are planned and built, and the services and resources provided within them. Inspired by the results of our survey and based on user feedback from the pilot tests, a free online training program entitled "Public Health and Planning 101: An Online Course for Public Health and Planning Professionals to Create Healthier Built Environments" was launched in 2016 by OPHA as a collaborative project with OPPI and PHAC. This course is designed to bridge the gaps between the two professions, as well as provide greater opportunities for developing collaborative partnerships to help create and foster healthy built environments.

Abstract
BACKGROUND Anti-neutrophil cytoplasmic antibody (ANCA) -associated vasculitis (AAV) is a disease characterized by inflammation of small vessels and detectable ANCA in the circulation. Patients may develop a broad spectrum of clinical features ranging from indolent sino-nasal disease and rashes to fulminant renal failure or acute life-threatening pulmonary haemorrhage. Consequently, patients with AAV present to a variety of specialties including nephrology and rheumatology, whose training and approaches to management of such patients may differ. There is little literature comparing patients presenting to different specialties and their outcomes. METHODS We compared two cohorts of patients with ANCA-positive AAV presenting to either the rheumatology or nephrology department at Galway University Hospitals from June 2002 to July 2011. A standardized data collection form was used to collect information regarding baseline demographics, manifestations of AAV, initial management, relapses and complications. RESULTS Forty-five patients were included in this study (15 rheumatology/30 nephrology). The nephrology cohort was older, had a higher C-reactive protein, Birmingham Vascular Activity Score and ANCA titer at presentation compared to the rheumatology group. Induction treatment varied between the cohorts with rheumatology patients most commonly receiving a combination of oral corticosteroids (73%) and methotrexate (60%) and nephrology patients receiving a combination of intravenous corticosteroids (93%) and cyclophosphamide (90%). Fifty-three percent of the rheumatology patients who completed induction therapy relapsed compared to 30% of the nephrology patients. CONCLUSION This study presents two different cohorts of patients with the same disease that were managed by two different disciplines. It highlights the heterogeneity of AAV and the importance of interdisciplinary communication and cooperation when managing these patients.

Abstract
Oxidized low-density lipoprotein (oxLDL) is believed to play a central role in the development of atherosclerosis. The induction of apoptosis in cells of the arterial wall is a critical event in the development of atheroma. 7β-Hydroxycholesterol (7 β-OH) and cholesterol-5 β,6 β-epoxide ( β-epoxide) are components of oxLDL and have previously been shown to be potent inducers of apoptosis. The exact mechanism through which these oxysterols induce apoptosis remains to be fully elucidated. A perturbation of intra-cellular calcium homeostasis has been found to trigger apoptosis in many experimental systems. The aim of the present study was to determine the involvement of calcium signaling in 7 β-OH and β-epoxide–induced apoptosis. To this end, the authors employed the calcium channel blockers verapamil and nifedipine and inhibitors of calpain activation, ALLM and ALLN. Verapamil protected against the decrease in viability induced by 7 β-OH whereas nifedipine had a protective effect in both 7 β-OH and β-epoxide–treated cells, though these compounds did not restore viability to control levels. Verapamil, nifedipine, and ALLM prevented apoptosis induced by β-epoxide. None of the compounds employed in the current study protected against 7 β-OH–induced apoptosis. Our results implicate calcium signaling in the apoptotic pathway induced by β-epoxide and also highlight differences between apoptosis induced by 7 β-OH and β-epoxide.

Abstract
Increasingly, evidence suggests a role for polyphenols in blood glucose control. The objective of this systematic review was to evaluate the effect of polyphenol-rich sources in combination with carbohydrate sources on resulting postprandial glycaemic and insulin responses. A literature search was conducted using Medline, CINHAL and Web of Science databases. Selected studies included randomised controlled trials in which the association of polyphenol-containing food or beverage consumption with a carbohydrate source and effect on acute postprandial glycaemia and/or insulin was reported. A total of thirteen full articles were included in the review. Polyphenol sources included coffee, black tea, fruit juice, plant extracts, berries and different rye breads, and carbohydrate sources included bread, pancakes and simple sugars such as sucrose, glucose and fructose. Although glycaemic and insulin responses differed depending on the polyphenol-carbohydrate combination, overall, polyphenol sources were shown to reduce the peak and early-phase glycaemic response and maintain the glycaemic response in the later stages of digestion. To a lesser extent, polyphenol sources were also shown to reduce peak insulin response and sustain the insulin response, especially when consumed with bread. This review supports epidemiological data suggesting that polyphenols in foods and beverages may have a beneficial effect on reducing the risk of type 2 diabetes. However, the extent of this effect is variable depending on the polyphenol and carbohydrate source.

Abstract
OBJECTIVES Ireland has the highest rate of vancomycin-resistant Enterococcus faecium (VREfm) isolated from blood of nosocomial patients in Europe, which rose from 33% (110/330) in 2007 to 45% (178/392) in 2012. No other European country had a VREfm rate from blood cultures of >25%. Our aim was to elucidate the reasons for this significantly higher rate in Ireland. METHODS The epidemiology and molecular typing of VRE from bloodstream infections (BSIs) was examined in a tertiary care referral hospital and isolates were compared with those from other tertiary care referral centres in the region. RESULTS The most common source of VRE BSIs was intra-abdominal sepsis, followed by line-related infection and febrile neutropenia. Most of the isolates were positive for vanA; 52% (43/83) possessed the esp gene and 12% (10/83) possessed the hyl gene. Genotyping by SmaI macrorestriction analysis (PFGE) of isolates revealed clonal relatedness between bloodstream isolates and environmental isolates. VRE BSI isolates from two other tertiary care hospitals in the Dublin region showed relatedness by PFGE analysis. MLST revealed four STs (ST17, ST18, ST78 and ST203), all belonging to the clonal complex of hospital-associated strains. CONCLUSIONS Irish VRE BSI isolates have virulence factor profiles as previously reported from Europe. Typing analysis shows the spread of individual clones within the hospital and between regional tertiary care hospitals. Apart from transmission of VRE within the hospital and transfer of colonized patients between Irish hospitals, no other explanation for the persistently high VREfm BSI rate in Ireland has been found.

Abstract
PURPOSE This study describes the incidence and outcomes of blunt cardiac injury (BCI) in a single trauma intensive care unit (TICU), together with the spectrum of thoracic injuries and cardiac abnormalities seen in BCI. METHODS We performed a retrospective observational study of 169 patients with blunt thoracic trauma admitted from January 2010 to April 2013. BCI was diagnosed using an elevated serum troponin in the presence of either clinical, ECG or transthoracic echocardiography (TTE) abnormalities in keeping with BCI. The mechanism of injury, associated thoracic injuries and TTE findings in these patients are reported. RESULTS The incidence of BCI among patients with blunt thoracic trauma was 50% (n=84). BCI patients had higher injury severity scores (ISS) (median 37 [IQR 29-47]; p=0.001) and higher admission serum lactate levels (median 3.55 [IQR 2.4-6.2], p=0.008). In patients with BCI, the median serum TnI level was 2823ng/L (IQR 1353-6833), with the highest measurement of 64950ng/L. TTEs were performed on 38 (45%) patients with BCI, of whom 30 (79%) had abnormalities. Patients with BCI had a higher mortality (32% vs. 16%; p=0.028) and trended towards a longer length of stay (17.0 days [standard deviation (SD) 13.5] vs. 13.6 days [SD 12.0]; p=0.084). CONCLUSIONS BCI was associated with an increased mortality and a trend towards a longer length of stay in this study. It is a clinically relevant diagnosis which requires a high index of suspicion. Screening of high risk patients with significant blunt thoracic trauma for BCI with serum troponins should be routine practise. Patients diagnosed with BCI should undergo more advanced imaging such as TTE or TOE to exclude significant cardiac structural injury.

Abstract
Many large-scale surveys measure subjective well-being (SWB) through a single survey item. This paper takes advantages of response time data to explore the relation between time taken to answer a single SWB item and the reliability and validity of answers to this SWB item. We found that reliability and validity of answers to the SWB item are low for fast respondents aged 70 and above and slow respondents between the age of 50 and 70. The findings indicate that longer time spent answering the single SWB item is associated with data of lower quality for respondents aged between 50 and 70, but data of higher quality for respondents aged 70 and above. This paper speaks to the importance of capitalizing response times that are readily available from computerized interviews to evaluate answers provided by respondents and calls for survey researchers' attention to differences in time taken to answer a survey question across respondent subgroups.

Abstract
Functional instability of the ankle is common following inversion sprain. Factors suggested as causes of this disability include mechanical instability of the talocrural joint, peroneal muscle weakness and motor incoordination due to impaired proprioception. This study documented physical examination characteristics of functionally unstable ankles relevant to these theories. Each ankle of 45 subjects with unilateral functional instability was examined. Mechanical stability was assessed by standard clinical instability tests. Evertor and inventor muscle strength was measured using the Cybex II dynamometer. The Uni-axial Balance Evaluator (UBE) was used to assess dynamic control of the ankle and was considered capable of detecting unilaterally impaired proprioception. Mechanical instability was frequently absent in the functionally unstable ankles tested. Evertor muscle strength was similar in the normal and functionally unstable ankles. UBE results were consistent with the theory of impaired proprioception contributing to functional instability, but the need for further research is emphasised.

Abstract
Abstract
Purpose: To describe the impact of California Breast Density Notification law (SB 1538) on policy development, policy implementation and supplemental screening strategies within California medical facilities. SB 1538 mandates that breast density information be given to patients but provides no funding for supplemental screening, no guidance on how to triage women for supplemental screening nor which imaging modalities to use.
Methods:
As a result of the law, the California Breast Density Information Group (CBDIG) formed from academic and private practice radiologists and risk assessment experts, reviewing scientific literature and nationally recognized guidelines to provide evidence-based recommendations regarding supplemental screening in women with dense breast tissue. A survey was sent to 6 academic and 3 large private practices in California to record their experience in implementing the law.
Results: CBDIG created a public, institution-neutral, evidence-based website, “breastdensity.info”, that includes information and recommendations regarding supplemental breast screening, with triage for supplemental MRI or US based on breast cancer risk assessment using genetic or family history risk models. CBDIG facilities worked with referring health care providers to inform them of the new law, educated their staff and technologists on implementing policy, and developed notification strategies to comply with legislation.
The survey showed that all 9 facilities recommended supplemental screening based on family history models or genetic testing. 3/9 calculated breast cancer risk in the breast imaging clinic, and 2/9 emailed a risk survey to the patient. 3/9 reported risk in the radiology report, and 1/9 reported risk only if the patient was high risk. Risk assessments were performed by technologists and risk assessment health practitioners. 8/9 facilities estimated breast density by visual methods, and 1/9 by computer. All facilities performed screening breast MRI, 4/9 performed handheld screening US, and 2/9 tomosynthesis. 1/9 obtained tomosynthesis in anticipation of the law, 2/9 are trying to obtain automated whole breast US, and 3/9 are trying to obtain tomosynthesis. Facilities expressed concerns about additional false-positive biopsies produced by supplemental screenings, out-of-pocket expenses for women, and disparities (low income) in notified populations.
Conclusion: SB 1538 resulted in the formation of the CBDIG and the website, “breastdensity.info”. Our survey showed variations in imaging modalities available and policy implementation at each facility. Given that several states currently have breast density laws or have laws that will become effective in the near future, it is important for breast imagers and clinicians to be informed of the current literature, realize the variation in equipment and policies at various facilities, and develop recommendation strategies to guide patients seeking supplemental screening. We plan to follow up this survey with a larger survey of the Society of Breast Imagers at a later date.

Abstract
Previous lesion studies have shown compromised complex object discrimination in rats, monkeys, and human patients with damage to the perirhinal cortical region (PRC) of the medial temporal lobe. These findings support the notion that the PRC is involved in object discrimination when pairs of objects have a high degree of overlapping features but not when object discrimination can be resolved on the basis of a single feature (e.g., size or color). Recent studies have demonstrated age-related functional changes to the PRC in animals (rats and monkeys) resulting in impaired complex object discrimination and object recognition. To date, no studies have compared younger and older humans using paradigms previously shown to engage the PRC. To investigate the influence of age on complex object discrimination in humans, the present study used an object matching paradigm for blob-like objects that have previously been shown to recruit the PRC. Difficulty was manipulated by varying the number of overlapping features between objects. Functional MRI data was acquired to determine the involvement of the PRC in the two groups during complex object discrimination. Results indicated that while young and older adults performed similarly on the easy version of the task, most older adults were impaired relative to young participants when the number of overlapping features increased. fMRI results suggest that older adults do not engage bilateral anterior PRC to the same extent as young adults. Specifically, complex object matching performance in older adults was predicted by the degree to which they engage left anterior PRC. These results provide evidence for human age-related changes in PRC function that impact complex object discrimination.
