Abstract
Abstract
Background
Chronic Kidney Disease (CKD) is an important risk factor in the development of cognitive impairment. However, the association between reduced estimated Glomerular Filtration Rate (eGFR) and performance on domain-specific cognitive and neuropsychological assessments is less clear and may represent an important target in the promotion of optimal brain health in older adults.
Methods
Participants from the Trinity, Ulster and Department of Agriculture cohort study underwent detailed assessment of cognitive and neuropsychological function using the Mini-Mental State Examination (MMSE), Frontal Assessment Battery (FAB) and Repeatable Battery for Assessment of Neuropsychological Status (RBANS). Mixed-effects Poisson and linear regression was used to assess the relationship between eGFR strata and cognitive/neuropsychological test performance.
Results
4,887 participants were included (73.94 ± 8.25 years; 67.7% female). Reduced eGFR was associated with poorer performance on all three cognitive assessments, most pronounced in those with eGFR <45 mL/mL/1.73m2 (IRR: 1.19; 95% CI: 1.09, 1.29; p < 0.001 for MMSE/IRR: 1.14; 95% CI 1.04, 1.24; p < 0.001 for the FAB/β: -3.23; 95% CI -5.18, −1.30; p = 0.001 for RBANS, fully adjusted). Reduced eGFR was associated with poorer performance on immediate memory, visual–spatial and attention RBANS domains. Associations were strongest in the youngest old (<70 years) with no association observed in those aged >80 years.
Conclusion
Reduced kidney function was associated with poorer global and domain-specific function in community-dwelling older adults. Associations were strongest for those with eGFR <45 mL/min/1.73m2 and the youngest-old, suggesting that this group may be most at risk and may benefit from potential preventative interventions.

Abstract
Abstract
Background
Cocooning, i.e. staying at home and reducing interaction with others, was a key part of the strategy to protect older people during the COVID-19 pandemic.
Unfortunately, there are concerns this has had a negative impact on the physical and mental wellbeing of those who have been isolated.
Methods
We completed a survey of 150 patients (55% female, mean age 79.8 years, average Clinical Frailty Scale 4.8) attending ambulatory medical services in a large university hospital.
Questions were focused on: access to healthcare services, mental health, physical health, and attitudes to COVID-19 restrictions.
Results
Almost 40% reported that their mental health was ‘worse’ or ‘much worse’ while cocooning, while over 40% reported a decline in their physical health.
Over 57% had a scheduled healthcare-related visit cancelled while cocooning, most frequently hospital outpatient appointments.
Worryingly, almost 1/6 reported not seeking medical attention for an illness that they would usually. Of these, half did not as they were worried about catching COVID and 46% did not as this service was not currently available to them.
Conclusion
The COVID-19 pandemic and lack of access to essential services, both medical and social, has had a devastating impact on older people.
This is evident in both the acute presentations to hospital and the longer-term impact it has had on health and function.
It is important that in the future clear policies are in place to enable older people to access care when they need it.

Abstract
BACKGROUND There is minimal information on the utilisation of Disease Modifying Treatment (DMTs) for multiple sclerosis. The appropriate and safe use of medicines is informed by utilisation studies. Outcomes can inform health interventions to improve appropriate use of medicines and post marketing surveillance activities to improve safety. OBJECTIVE To evaluate utilisation and treatment patterns of disease modifying treatments (DMTs) for relapsing remitting multiple sclerosis (RRMS). METHODS A representative sample of the Australian pharmaceutical benefits scheme data were analysed (2006-2016). Demographics of incident users and trends in incident and prevalent users were determined. Individual patient treatment pathways were determined by sequential initiation of medicines in two different periods (2006-2013 and 2014-2019). RESULTS There were 20,660 patients with at least one dispensing of a DMT for RRMS during the study period (median age 41 years, 75% female). Incident and prevalent use increased by 20% and 88%, respectively. The market was responsive to 13 new listings of DMTs over the study period. Sequential treatment was found for 66% of initiators in 2006-2013 and 28.5% of initiators in 2014-2019. Diverse treatment pathways were found, with 278 and 93 unique sequences in 2006-2013 and 2014-2019, respectively. CONCLUSION The availability of new DMTs has influenced both initial treatment choice and prevalence of users. Individualised treatment patterns and exposure to multiple medicines over time will challenge traditional pharmacovigilance systems.

Abstract
Abstract
Background
Vitamin D fortified milk is used by some older adults to boost vitamin D status. Combined vitamin D/calcium supplements often cause gastrointestinal upset which reduces adherence. Consumption of fortified milk may be a more consistent and reliable way of increasing serum 25 hydroxyvitamin D [25(OH)D], though studies of it’s efficacy in older adults are limited.
Methods
We examined the vitamin D status of users of vitamin D fortified milk in participants of a longitudinal study of community dwelling Irish adults aged >60 yrs. Patients taking vitamin D supplements were excluded and independent effects were explored in multinomial regression models. Vitamin D deficiency was defined as a 25(OH)D level < 30 nmol/l.
Results
2496 participants were identified: mean age was 70.5 ± 7.0 years (range 60–96 yrs) and 145 (5.8%) reported using vitamin D fortified milk. In those who consumed fortified milk, there was a lower prevalence of vitamin D deficiency (17.9 vs 34.5%, P < 0.001). Vitamin D fortified milk also predicted less deficiency after adjusting for age, gender, season, BMI and physical frailty (OR 0.30. CI 0.19–0.48, P < 0.001).
Conclusion
Vitamin D fortified milk was associated with a 70% reduction in the risk of vitamin D deficiency in older adults not taking vitamin D supplements. Findings support the use of vitamin D fortified milk as an effective means of improving vitamin D status. Fortified milk also contains additional calcium and so can be used to augment daily calcium intake.

Abstract
Background ‘Wish to Die’ (WTD) involves thoughts of or wishes for one’s own death or that one would be better off dead. Assisted dying is the act of deliberately providing medical assistance to another person who wishes to end their own life. Currently, in Ireland, it is illegal to provide such assistance to people with WTD or suicidal ideation. However, a new bill that would legalise assisted dying for those with terminal illnesses, the Dying with Dignity Bill 2020, is due to be considered by lawmakers in Ireland in the coming months. In order to inform discussion around this complex issue, we examine the prevalence and longitudinal course of WTD in a large population-representative sample of older people. Methods To define WTD, participants were asked: ‘In the last month, have you felt that you would rather be dead?’ Depressive symptoms were measured using the CES-D. Mortality data were compiled by linking administrative death records to individual-level survey data from the study. Results At Wave 1, 3.5% of participants (279/8,174) reported WTD. Both persistent loneliness (OR 5.73 (95% CI 3.41–9.64)) and depressive symptoms (OR 6.12 (95% CI 4.33–8.67)) were independently associated with WTD. Of participants who first reported WTD at Wave 1 or 2, 72% did not report WTD when reassessed after 2 years, and the prevalence of depressive symptoms (−44%) and loneliness (−19%) was more likely to decline in this group at follow-up. Fifteen per cent of participants expressing WTD at Wave 1 died during a 6-year follow-up. Conclusion WTD amongst community-dwelling older people is frequently transient and is strongly linked with the course of depressive symptoms and loneliness. An enhanced focus on improving access to mental health care and addressing social isolation in older people should therefore be a public health priority, particularly in the current context of the Covid-19 pandemic.

Abstract
Abstract
Background
Fear of falling is common in older adults and is associated with social isolation, reduced quality of life, depression and increased mortality. We aimed to investigate the factors associated with fear of falling in a cohort of older Irish adults.
Methods
Our study included adults aged ≥60 years attending outpatient services and recruited as part of the TUDA (Trinity, Ulster and Department of Agriculture) study. Physical frailty was measured with the Timed Up and Go (TUG), cognition with the Mini Mental State Examination (MMSE) and depression with the Center for Epidemiological Studies Depression scale (CES-D). Factors associated with fear of falling were explored in multinomial regression models.
Results
5185 adults were included, 67.3% female and mean age 74.0 ± 8.3 yrs. Fear of falling varied by age: 39.4% (60-70 yrs), 51.2% (70-80 yrs), 70.4% (80 + yrs). Independent positive predictors of fear of falling were age (beta 0.01, P = 0.030), female gender (OR 2.6, CI 2.2–3.2, P < 0.001), fall in the previous year (OR 1.9, CI 1.6–2.3, P < 0.001), depression (CES-D ≥ 16) (OR 1.7, CI 1.3–2.2, P < 0.001), use of osteoporosis medications (OR 1.3, CI 1.1–1.6, P = 0.002), self reported dizziness on standing (OR 1.5, CI 1.3–1.8, P < 0.001), physical frailty (TUG >12 seconds, OR 1.30, CI 1.1–1.6, P = 0.004) and limiting outside activities (OR 16.3, CI 13.8–19.3, P < 0.001).
Conclusion
We identified a high prevalence of fear of falling, though our study sample included frail older adults attending geriatric outpatient services. Those who fell in the last year and who were female were about twice as likely to fear falling. It was also more likely in those who were physically frailer, taking osteoporosis medications and reporting orthostatic symptoms. Notably those with a fear of falling were 70% more likely to be depressed and 16 times more likely to limit outside activities highlighting its negative impact.

Abstract
Background The coronavirus 2019 (COVID-19) pandemic impacted significantly on the lives of older adults in Ireland, including the cancellation or postponement of healthcare services. This study examined the relationship between healthcare delay and older adults (50 years and over) with chronic conditions in Ireland. Methods This study used data from the Irish Longitudinal Study on Ageing (TILDA) COVID-19 study and previous waves of TILDA. The COVID-19 study data was collected between July 2020 and November 2020. Taking existing healthcare demand into account, logistic regression analysis was used to examine the relationship between healthcare delay and older adults with chronic conditions. Additional analysis, using multinomial logit regression, explored the reasons for healthcare delay, whether the delays were on the participants behalf or the health service provider. Results In total, 31.6% of participants reported healthcare delay. Older adults with two or more chronic conditions were more likely to experience healthcare delay than those with no chronic conditions. In the second analysis, older adults with two or more chronic conditions were more likely to have healthcare delayed by the provider and were also more likely to delay their own healthcare than those with no chronic conditions. Additionally, some other groups were more likely to experience healthcare delay such as: people aged 70 years and over, females, those with problematic alcohol consumption, those with third-level education, those who had visited the GP and those who reported polypharmacy. While older adults living with others and those living outside Dublin were less likely to experience healthcare delay. Conclusion The findings suggest that some groups of older adults may have been impacted more than others by healthcare delay during the pandemic. Policy and practice should focus on effective strategies to support the healthcare needs of these older adults going forward. Additionally, future research should examine the implications of healthcare delay on health outcomes.

Abstract
Abstract
Background
The main mode of transportation in Ireland remains travel by car. Transport mobility is important for older adults in accessing shops, healthcare, services, community and in maintaining relationships. Cessation of driving is associated with negative effects on mental health, loneliness and physical health. We aimed to explore factors associated with driving status in older adults living in an urban environment.
Methods
Study included adults aged greater than 65 years attending a geriatric outpatient service in an urban environment and recruited as part of the TUDA (Trinity Ulster, Department of Agriculture) study. We excluded those with a MMSE (Mini-Mental State Exam) less than 24 as we aimed to include only non-dementia patients. Physical frailty was measured with the Timed Up and Go (TUG) and depression with the Center for Epidemiological Studies Depression scale (CES-D). Factors associated with driving status were explored in multinomial regression models.
Results
1978 adults, mean age 77.7 ± 7.1 years, 76.0% were female. 35.5% were current drivers but this differed by age category 45.9% (65–75 years), 25% (75–85 years) and 12.5% (85+ years). 28.1% were past drivers. Positive independent predictors of current driving were younger age (P < 0.001), male gender (P < 0.001), married status (P = 0.01), higher socioeconomic status (P < 0.0001) while negative predictors included physical frailty (TUG, P < 0.001), visual impairment (P = 0.01), stroke (P < 0.001), depression (P < 0.001) and self reported loneliness (P = 0.01).
Conclusion
One third of patients attending a geriatric outpatients in an urban environment were currently driving which is much lower than in the general older Irish population. However, our study included frail adults living in more deprived socioeconomic areas and had a high proportion of females who had never learned to drive. Furthermore, access to urban public transport may be a factor. Non-drivers were more likely to have depression and report loneliness independent of other factors highlighting its negative impact.

Abstract
BACKGROUND Cocooning or shielding, i.e. staying at home and reducing face-to-face interaction with other people, was an important part of the response to the COVID-19 pandemic for older people. However, concerns exist regarding the long-term adverse effects cocooning may have on their physical and mental health. AIM To examine health trajectories and healthcare utilization while cocooning in a cohort of community-dwelling people aged ≥70 years. DESIGN Survey of 150 patients (55% female, mean age 80 years and mean Clinical Frailty Scale Score 4.8) attending ambulatory medical services in a large urban university hospital. METHODS The survey covered four broad themes: access to healthcare services, mental health, physical health and attitudes to COVID-19 restrictions. Survey data were presented descriptively. RESULTS Almost 40% (59/150) reported that their mental health was 'worse' or 'much worse' while cocooning, while over 40% (63/150) reported a decline in their physical health. Almost 70% (104/150) reported exercising less frequently or not exercising at all. Over 57% (86/150) of participants reported loneliness with 1 in 8 (19/150) reporting that they were lonely 'very often'. Half of participants (75/150) reported a decline in their quality of life. Over 60% (91/150) agreed with government advice for those ≥70 years but over 40% (61/150) reported that they disliked the term 'cocooning'. CONCLUSIONS Given the likelihood of further restrictions in coming months, clear policies and advice for older people around strategies to maintain social engagement, manage loneliness and continue physical activity and access timely medical care and rehabilitation services should be a priority.

Abstract
The DEAP-3600 detector searches for the scintillation signal from dark matter particles scattering on a 3.3 tonne liquid argon target. The largest background comes from 39 Ar beta decays and is suppressed using pulse-shape discrimination (PSD). We use two types of PSD estimator: the prompt-fraction, which considers the fraction of the scintillation signal in a narrow and a wide time window around the event peak, and the log-likelihood-ratio, which compares the observed photon arrival times to a signal and a background model. We furthermore use two algorithms to determine the number of photons detected at a given time: (1) simply dividing the charge of each PMT pulse by the mean single-photoelectron charge, and (2) a likelihood analysis that considers the probability to detect a certain number of photons at a given time, based on a model for the scintillation pulse shape and for afterpulsing in the light detectors. The prompt-fraction performs approximately as well as the log-likelihood-ratio PSD algorithm if the photon detection times are not biased by detector effects. We explain this result using a model for the information carried by scintillation photons as a function of the time when they are detected.

Abstract
OBJECTIVE To describe the incidence, morphology and clinical significance of congenital vertebral malformations (CVM) in two breeds of brachycephalic dogs presenting to a referral veterinary hospital. DESIGN Prospective cohort study series. MATERIALS AND METHODS Forty-nine French Bulldogs and Pugs were prospectively evaluated and placed in one of two groups based on whether or not they presented for neurological signs referable to spinal cord disease. A computed tomography (CT) of their entire spine was obtained and the presence and classification of CVM along with the degree of spinal kyphosis recorded for all dogs. Statistical analysis was performed to identify clinical associations between these factors (P < 0.05). RESULTS CVM were prevalent across both breeds with the French Bulldog having more malformations than the Pug (Kruskal-Wallis nonparametric analysis of variance, P < 0.0001). Breed associated vertebral malformation subtypes included butterfly subtype in French Bulldogs (Chi-square, P = 0.0002), and transitional subtype in Pugs (odds ratio, 22.7; P = 0.000). A new subtype, dorsal wedge, was observed in 12 cases. The presence, number and subtype of vertebral malformation were not reliable for predicting the development of neurological signs across both breeds (Chi-square, P > 0.05). However, spinal kyphosis >35° calculated via Cobb angle was associated with Pugs that had neurological deficits (Chi-square, P = 0.028). CONCLUSIONS Congenital vertebral malformations largely appear to be incidental findings in this population of French Bulldogs but are of more significance in the Pug breed when spinal kyphosis is >35°. French Bulldogs that have spinal cord disease and CVM are more likely to have pathology distant to CVM with intervertebral disc herniation most common.

Abstract
Objectives Schools in the Republic of Ireland reopened to students and staff in late August 2020. We sought to determine the test positivity rate of close contacts of cases of coronavirus disease 2019 (COVID-19) in schools during the first half-term of the 2020/2021 academic year. Methods National-level data from the schools' testing pathway were interrogated to determine the positivity rate of close contacts of cases of COVID-19 in Irish primary, postprimary and special schools during the first half-term of 2020/2021 academic year. The positivity rates among adult and child close contacts were compared and the proportion of national cases of COVID-19 who were aged 4–18 years during the observation period was calculated to assess whether this proportion increased after schools reopened. Results Of all, 15,533 adult and child close contacts were tested for COVID-19 through the schools' testing pathway during the first half-term of the 2020/2021 academic year. Three hundred and ninety-nine close contacts tested positive, indicating a positivity rate of 2.6% (95% confidence interval: 2.3–2.8%). The positivity rates of child and adult close contacts were similarly low (2.6% vs 2.7%, P = 0.7). The proportion of all national cases of COVID-19 who were aged 4–18 years did not increase during the first half-term of the 2020/2021 school year. Conclusions The low positivity rate of close contacts of cases of COVID-19 in schools indicate that transmission of COVID-19 in Irish schools during the first half-term of the 2020/2021 academic year was low. These findings support policies to keep schools open during the pandemic.

Abstract
Background:Remission is the stated goal for both patient and care-giver (1), but consensus on a definition of remission has been lacking. Previously, an international task force consisting of patient representatives and medical specialists published a frame-work for such a definition (2), but without making a final recommendation.Objectives:To achieve consensus around a definition of remission in SLE (DORIS).Methods:The DORIS task force met annually from 2015 to 2020 and consisted of patient representatives and specialists in rheumatology, nephrology, dermatology, and clinical immunology. Systemic literature reviews of several key topics were done and specific research questions were examined in suitably chosen datasets. The findings were discussed, reformulated as recommendations, and voted upon. Level of evidence (LoE), strength of recommendation (SoR), and agreement were determined in standard fashion. The final recommendation for the DORIS definition of remission was established by electronic vote after finalization of the minutes of the most recent task force meeting.Results:Based on data from the literature and from several SLE-specific data sets, five key recommendations were endorsed (Table 1) that should be seen as additions to those published previously (2). Literature reviews identified strong support for the face-, content-, construct- and criterion validity of the definition based on the clinical SLEDAI (not including anti-DNA and complement) equal to zero plus low physician global assessment and allowing stable medical treatment. Thus, the DORIS Task Force recommended a single definition of remission in SLE, based on clinical SLEDAI = 0, evaluator’s global assessment <0.5 (0-3), prednisone 5 mg/day or less, and stable antimalarials, immunosuppressives and biologics.Table 1.Vote in favorLoESoRAgreement1.Inclusion of serology [anti-DNA, complement] in the DORIS definition of remission-on-treatment does not meaningfully alter the construct validity and therefore it is not recommended to include it90%2aB8.382.While the goal of treatment is sustained remission, a definition of remission should be able to be met at any point in time; therefore, duration should not be included in the definition100%5C9.023.To date, the SLEDAI-based definitions of remission have formally been investigated more extensively than BILAG-or ECLAM-based definitions. The SLEDAI-based definitions can therefore more confidently be recommended91%2aB9.254.Remission off treatment, while the ultimate goal for many patients and providers, is achieved very rarely. In clinical research and as an outcome in clinical trials, the definition for remission-on-treatment is recommended92%2aB9.525.In clinical trials, the LLDAS definition for low disease activity and the DORIS definition of remission are both recommended as outcomes100%5C9.25The 2021 DORIS definition of remission in SLE:Conclusion:The 2021 DORIS definition of remission in SLE was established. It is recommended for use as an aspirational treatment target in clinical care, a clear concept in education, and a key outcome in research including clinical trials and observational studies.References:[1]van Vollenhoven RF, Mosca M, Bertsias G, et al.

Abstract
Abstract
Hypertrophic obstructive cardiomyopathy (HOCM) is characterized by muscle hypertrophy and fibrosis, interfering with force generation and relaxation. Abnormal ventricular (LV) myocardial deformation have been demonstrated in patients with HOCM at rest, but there is lack of data regarding the deformational mechanics in exercise in obstructive HCM.
Aims
To assess the adaptability of LV deformational behaviour to physical exercise in HOCM patients as compared to healthy controls and to examine if Deformational Imaging (DMI) can provide additional information.
Methods
28 obstructive HOCM (age 51.2±14.2yrs; 16 men, LVOT-obstruction 56±19mmHg at rest or on Valsalva maneuver) and 32 control subjects (50.9±6.8 yrs, 19 men from the MAGYAR-PATH Registry) underwent bicycle stress Echo (ESE) with full conventional 2D- and Doppler TTE, 2D- and 3D-Speckle Tracking Analysis (DMI) and 3D-Full Volume assessment both at rest and on submaximal ESE.
Results
At rest, the HOCM group had lower GLS (−14.6±4.5 vs 18.4±2.6%, p<0.01) but higher CS (−32.9±5.1 vs 28.8±2.3%) and Twist (9.9±2.6 vs 6.1±2.2°) than in control subjects. Exercise induced an increase in all strains in control subjects but less in HOCM (GLS: −21.4±3.5 vs 15.1±3.0% and CS: −33.9±3.6 vs 34.1±4.2% in controls). The increase of LV twist was blunted in HOCM (Δ1.2 vs Δ3.6° in controls). The PSS was more pronounced in HOCM on ESE (46.6±12.0 vs 21.2±9.6%, AUC: 0.71 for predicting HOCM), the UTR was slower (118±2.1 vs 133.1±14.1°/s) and occurred later in HOCM. The MD of Strain increased in HOCM on ESE (Δ85.1 vs Δ8.1ms in controls). The Twist had positive correlation with LVOT-obstruction (R2=0.54, p<0.01) and inverse correlation with UTR (R2=−0.72, p<0.02). The UTR/Twist ratio diminished only in HOCM on exercise (−6.0±0.8 vs −13.1±2.5 1/s). The MD, the PSS on ESE and the UTR/Twist ratio predicted the HOCM deformation phenotype accurately (AUC: 0.72, cut-off 6.0 1/s).
Conclusions
The HOCM patients had attenuated Strain and Rotational response on exercise implying impaired deformational adaptability with post-systolic shortening and pronounced mechanical dispersion of peak Strain on exercise which was more accurate to identify the HOCM phenotype than other Echo-indices. These findings support evidence for reduced systolic-diastolic coupling efficiency in HOCM patients on exercise which can contribute to the development of exercise-related breathlessness, dynamic LVOT-obstruction and arrhythmias in patients with HOCM. These distinct deformational patterns on exercise can help in the differential diagnosis of patients with LV hypertrophy of unknown aetiology with good sensitivity and specificity and can also aid in the risk stratification workup in HOCM.

Abstract
Abstract
Health as it is reported in mainstream media is narrow and communities are often excluded, despite being where the experience of health occurs. A wide range of research indicates that it is through narratives of community members that media and health messages are best conveyed, and community members now have a range of platforms for quickly conveying information to each other and the media. However, there have been surprisingly few innovations for journalists to use this material, or to better connect with the public and report more accurately about health.
Our experience across several journalism projects demonstrates how quickly and deeply health content can be developed in collaboration with communities. One example is #CroakeyGO - an innovation in public interest journalism that gathers, walks and talks with community members together at a defined time and location about health-related matters.
#CroakeyGO brings together diverse voices from local communities - people who might otherwise not connect. This stimulates discussion about health issues beyond the individual, including system- and environmental-level issues that impact local lives. #CroakeyGO also means respecting Indigenous peoples' connection to Country on which we walk and reflecting on intergenerational inequities and solutions Indigenous knowledges offer.
To date we have published more than 40 articles from #CroakeyGO events around metropolitan and regional Australia. We have collaboratively produced social media and other editorial content with community members and stimulated enduring networks for health planning, advocacy and research. #CroakeyGO reinforces that improving health in a community requires more than just additional services, and that transformations in journalism can facilitate and support rather than hinder collective action.
Key messages
Innovations in journalism are required and possible to improve health reporting. Communities are willing to engage in health reporting.

Abstract
OBJECTIVES To describe a cross-border foodborne outbreak of Shigella sonnei that occurred in Ireland and Northern Ireland (NI) in December 2016 whilst also highlighting the valuable roles of sales data and international collaboration in the investigation and control of this outbreak. STUDY DESIGN A cross-border outbreak control team was established to investigate the outbreak. METHODS Epidemiological, microbiological, and environmental investigations were undertaken. Traditional analytical epidemiological studies were not feasible in this investigation. The restaurant chain provided sales data, which allowed assessment of a possible increased risk of illness associated with exposure to a particular type of heated food product (product A). RESULTS Confirmed cases demonstrated sole trimethoprim resistance: an atypical antibiogram for Shigella isolates in Ireland. Early communication and the sharing of information within the outbreak control team facilitated the early detection of the international dimension of this outbreak. A joint international alert using the European Centre for Disease Control's confidential Epidemic Intelligence Information System for Food- and Waterborne Diseases and Zoonoses (EPIS-FWD) did not reveal further cases outside of the island of Ireland. The outbreak investigation identified that nine of thirteen primary case individuals had consumed product A from one of multiple branches of a restaurant chain located throughout the island of Ireland. Product A was made specifically for this chain in a food production facility in NI. S. sonnei was not detected in food samples from the food production facility. Strong statistical associations were observed between visiting a branch of this restaurant chain between 5 and 9 December 2016 and eating product A and developing shigellosis. CONCLUSIONS This outbreak investigation highlights the importance of international collaboration in the efficient identification of cross-border foodborne outbreaks and the value of using sales data as the analytical component of such studies.

Hypertrophic obstructive cardiomyopathy (HOCM) is characterized by muscle hypertrophy and fibrosis, interfering with force generation and relaxation. Abnormal ventricular (LV) myocardial deformation have been demonstrated in patients with HOCM at rest, but there is lack of data regarding the deformational mechanics in exercise. AIMS: We wanted to assess the adaptability of LV deformational behaviour to physical exercise in HCM patients as compared to healthy control subjects.
METHODS
24 obstructive HOCM (age 51.2 ± 14.2yrs; 16 men, LVOT-obstruction 56 ± 19mmHg at rest or on Valsalva maneuver) and 32 control subjects (50.9 ± 6.8 yrs, 19 men from the MAGYAR-PATH Registry) underwent supine bicycle stress echocardiography (ESE) with measurements of 2D- and Doppler, 2D-Speckle Tracking Tracking Imaging and 3D-Full Volume Analysis. Beyond conventional LV/RV functional measurements; peak longitudinal (LS), circumferential (CS) Strain values; peak Twist and Torsion angles; post-systolic shortening index (PSS) and diastolic phase indices (Untwisting time - UTT and rate - UTR) calculated; the UTR/Twist ratio was given as "coupling index". The LV/RV-EF calculated by 3D-Full Volume Analysis off-line by TomTec Arena™ software both at rest and on submaximal ESE.
RESULTS
The HOCM group had lower resting LS (-14.6 ± 4.5 vs 18.4 ± 2.6%, p < 001) but higher CS (-32.9 ± 5.1 vs 28.8 ± 2.3%, p < 0.001) and Twist angles (9.9 ± 2.6 vs 6.1 ± 2.2º, p < 0.01) than control subjects. Exercise induced an increase in all strains in control subjects, but much less in HOCM (LS: -21.4 ± 3.5 vs 15.1 ± 3.0% and CS: -33.9 ± 3.6 vs 34.1 ± 4.2% in HOCM, p < 0.02 in controls, NS in HOCM); the increase of Twist angle was minimal in HOCM (Δ1.2 ± 1.2 vs Δ3.6 ± 2.3º in controls, p < 0.01). The PSS was more pronounced on ESE in HOCM than in controls (46.6 ± 12 vs 21.2 ± 9.6% in controls, p < 0.001). Peak UTR was slower (118 ± 2.1 vs 133.1 ± 14.1 º/s) during ESE and occured later (141 ± 19 vs 121 ± 9.1% of systolic time, p < 0.02) in HOCM than in controls. There was significant relationship between the Twist and UTR in control subjects (β=-0.0807, p < 0.001), but not in HOCM (β=-0.0046, p = 0.05). The UTR/Twist ratio diminished only in HOCM but not in controls (-8.0 ± 0.6 vs -13.1 ± 2.5 1/s, p < 0.02).
CONCLUSIONS
The HOCM patients had significantly impaired strain-adaptability; developed post-systolic shortening and no LV Torsional reserve was found on exercise. Also, I detected decreased and delayed UTR indices in the HOCM group. These findings support evidence for reduced systolic-diastolic coupling efficiency, assessed by Twist-Untwist mechanics in HOCM patients, which can contribute to the development of exercise-related symptoms and the dynamic LVOT-obstruction. This unique pattern of deformational behaviour to exercise can help in the differential diagnostic workup in patients with LV hypertrophy of unknown aetiology and also would hold additional value in the risk stratification process for patients with HCM-phenotypes.
