ABSTRACT
BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic impacted cancer services worldwide. We examined the effect of the first three pandemic waves on the number of electronic (e)-referrals to rapid access clinics (RACs) for breast, lung and prostate cancer in Ireland. METHODS: This study used a retrospective, repeated cross-sectional design. The predicted weekly number of e-referrals by suspected cancer types from March 2020 to May 2021 was calculated using the Holt-Winters seasonal smoothing method, based on the observed numbers from a representative pre-pandemic period (01 January 2019 to 01 March 2020) and compared this with the observed number across the first three pandemic waves (02 March 2020 to 09 May 2021). Percentage differences were calculated between observed and predicted numbers of e-referrals for the three RACs and patterns were examined in each wave. RESULTS: Observed e-referrals were lower than predicted for all three RACs in the first wave of the pandemic (15.7% lower for breast, 39.5% lower for lung and 28.1% lower for prostate) with varying levels of recovery in the second and third waves for the three e-referral types. CONCLUSIONS: The COVID-19 pandemic impacted patterns of e-referrals to RACs in the first three pandemic waves in Ireland. Early identification of changes in engagement with health services, such as a decrease in primary care presentations with a resultant decrease in e-referrals to RACs can allow for a rapid response from cancer control programmes. Continued surveillance of the impact of service disruption on cancer services allows policy makers and strategic leaders in cancer control programmes to respond rapidly to mitigate the impact on cancer outcomes.
ABSTRACT
AIMS: We aim to describe the epidemiology of ischaemic stroke and in-hospital mortality associated with stroke among men and women with and without diabetes from 2005 to 2015. METHODS: Secondary data analysis of national hospital discharge data from the Hospital Inpatient Enquiry database. Stroke incidence and in-hospital mortality rates in people with and without diabetes were calculated. Poisson regression models were used to estimate the incidence rate ratio (IRR) and assess trends over time. RESULTS: The age-adjusted incidence of stroke was twice as high in people with diabetes compared to those without diabetes (men IRR 2.0 [95% CI 1.95-2.06] and women IRR 2.2 [95% CI 2.12-2.27]). The incidence of ischaemic stroke decreased by an average 1.7% per year in men with diabetes and 3.3% per year in women with diabetes. In people without diabetes, the average annual reduction was smaller (0.2% per year in men and 1% per year in women). In-hospital mortality associated with admission with ischaemic stroke was approximately twice as high in those with diabetes compared to those without diabetes among men [IRR 1.81 (1.67-1.97)] and women [IRR 2 (95% CI 1.84-2.18)]. CONCLUSION: Despite decreases in incidence of ischaemic stroke and associated in-hospital mortality, there remains a twofold increased risk of ischaemic stroke and mortality in people with diabetes. Therefore, priority must be given to management of risk factors for ischaemic stroke in people with diabetes as well as continued development of targeted stroke prevention strategies.

Over 19,000 residents and health-care workers in 315 RCFs were swabbed in a once - off mass swabbing of residents and staff in residential care facilities (RCFs) in the Cork/Kerry region in Ireland in April and May 2020. This exercise was in response to epidemiological evidence demonstrating increasing community transmission of COVID-19 and emerging evidence of the vulnerability of older persons, particularly those with underlying medical conditions. The effectiveness of such strategies is uncertain and may depend on both the positive case yield and efficiency of testing turn-around to ensure that timely control measures are put in place. The overall positivity rate was 0.88% (n = 172). Mass swabbing allowed early identification of some new cases and outbreaks in RCFs. This facilitated early public health interventions to protect the most vulnerable members of society.
ABSTRACT
OBJECTIVES: There is limited evidence on the risk of in-flight transmission of SARS-CoV-2. This study estimated the extent of in-flight SARS-CoV-2 transmission on international flights arriving in Ireland during December 2020. STUDY DESIGN: This was a cross-sectional analysis. METHODS: National surveillance data identified all notified cases of COVID-19 who were infectious while travelling on international flights to Ireland during December 2020. Close contacts of cases were tested for SARS-CoV-2, and the results were collated to estimate the pooled secondary attack rate across all flights. Laboratory and epidemiological data were obtained from the Health Service Executive Covid Care Tracker, a national database of COVID-19 cases in Ireland. RESULTS: A total of 165 infectious cases of COVID-19 were identified on 134 incoming flights; 40.0% were symptomatic on board. There were 2099 flight close contacts identified, of whom 40.9% had results of a SARS-CoV-2 polymerase chain reaction test within 14 days of arrival. The pooled secondary attack rate for these contacts was 7.0% and was higher among those on flights of ≥5-hour duration (P = 0.008). More than half (59.1%) of close contacts had no SARS-CoV-2 test result recorded; the reasons included incorrect or absent contact details (26.5%) and no response when contacted (17.8%). CONCLUSIONS: In this national study investigating transmission of SARS-CoV-2 from international flights arriving into Ireland, the pooled secondary attack rate was 7.0%. International travel is likely to have contributed to the third wave of SARS-CoV-2 infections in Ireland in early 2021. Application of non-pharmaceutical interventions remains central to mitigating the risk of in-flight transmission.

International air travel has been highlighted as a concern since the beginning of the COVID-19 pandemic with respect to importation of cases. We summarise the available evidence for in-flight transmission of wild type SARS-CoV-2 during 2020, and for imported COVID-19 clusters to cause outbreaks. This paper provides a data baseline prior to the emergence of new mutations causing SARS-CoV-2 variants of concern, whose characteristics may increase the potential risk of in-flight transmission and imported outbreaks. The evidence on in-flight transmission of wild-type SARS-CoV-2 is limited, and is described in a small number of published reports. Most of the available evidence pertains to the early phase of the COVID-19 pandemic, during a period without non-pharmaceutical interventions such as distancing and in-flight mask wearing. There is considerable potential for outbreaks of COVID-19 from imported cases or clusters when public health guidance around quarantine of travellers and self-isolation of cases is not adhered to. Risks can be mitigated by measures such as: avoiding non-essential travel, targeted testing and quarantine of travellers from high incidence regions or regions of concern, managed quarantine processes, and protocols for rapid investigation and control of transmission from a possible variant of concern. Measures should be dynamically assessed and proportionate to the level of risk.

An outbreak of 59 cases of coronavirus disease (COVID-19) originated with 13 cases linked by a 7â¯h, 17% occupancy flight into Ireland, summer 2020. The flight-associated attack rate was 9.8-17.8%. Spread to 46 non-flight cases occurred country-wide. Asymptomatic/pre-symptomatic transmission in-flight from a point source is implicated by 99% homology across the virus genome in five cases travelling from three different continents. Restriction of movement on arrival and robust contact tracing can limit propagation post-flight.

We report the effectiveness of automated text messaging for active surveillance of asymptomatic close contacts of coronavirus disease (COVID-19) cases in the Cork/Kerry region of Ireland. In the first 7 weeks of the COVID-19 outbreak, 1,336 close contacts received 12,421 automated texts. Overall, 120 contacts (9.0%) reported symptoms which required referral for testing and 35 (2.6%) tested positive for COVID-19. Non-response was high (n = 2,121; 17.1%) and this required substantial clinical and administrative resources for follow-up.

BACKGROUND: The current advancement and increasing use of diagnostic imaging has led to increased detection of abdominal aortic aneurysms (AAA). Many of these patients are unfit for elective AAA surgery. AIM: To investigate the outcome of conservative management of unfit patients with large AAA (>5.5 cm) who are turned down for elective surgical intervention. PATIENTS AND METHODS: Between January 2006 and April 2017, 457 patients presented with AAA >5.5 cm. Seventy-six patients (M: F 54:22) were deemed unfit for elective repair. Mean age was 79.8 years (range 64-96). Mean AAA size was 60.22 mm (55-83). RESULTS: Forty-nine of the 76 patients (64%) had died by April 2017. Fifteen (19.7%) patients died directly because of their aneurysm rupture. A further 34 (44.7%) patients died from non-aneurysm-related causes. CONCLUSION: Patients with large AAA deemed unfit for elective surgery have an overall poor prognosis and die mainly from other causes than AAA. Surgical intervention when rupture occurs results in poor survival.

PURPOSE: We characterized the expression of sialomucin and sulphomucin in pouches fashioned for familial adenomatous polyposis and ulcerative colitis. We correlated sulphomucin expression with bacterial colonization and mucosal inflammation. METHODS: Ethical approval and informed consent were obtained. Mucosal biopsies from 9 patients with familial adenomatous polyposis and 12 with ulcerative colitis were obtained. Sulphomucin levels were assessed by using the high iron-diamine stain. Mucous gel layer composition was correlated with villous height, crypt depth, and total mucosal thickness. Mucous gel layer composition was correlated with acute and chronic inflammatory infiltrates. Colonization by a panel of seven bacterial species (including sulphate reducing bacteria) was established and correlated with sulphomucin levels. RESULTS: High-iron-diamine positivity (i.e., sulphomucin expression) was greater in ulcerative colitis pouch mucous gel (2.083 +/- 0.5 vs. 0.556 +/- 0.4, P = 0.003). Sulphomucin expression correlated with reduced crypt depth, villous height, and total mucosal thickness. In the ulcerative colitis group, chronic inflammatory infiltrate scores were significantly greater for high-iron-diamine-positive patients. Colonization by sulphate reducing bacteria was increased in high-iron-diamine-positive patients. CONCLUSIONS: Sulphomucin expression is increased in the mucous gel layer of the ulcerative colitis pouch compared with that of the familial adenomatous polyposis pouch. Sulphomucin expression is associated with colonization by sulphate-reducing bacteria and increased chronic inflammation.
