Long-term exposure to PM2.5 air pollution and mental health: a retrospective cohort study in Ireland.

BACKGROUND: Mental illness is the leading cause of years lived with disability, and the global disease burden of mental ill-health has increased substantially in the last number of decades. There is now increasing evidence that environmental conditions, and in particular poor air quality, may be associated with mental health and wellbeing. METHODS: This cross-sectional analysis uses data on mental health and wellbeing from The Irish Longitudinal Study on Ageing (TILDA), a nationally representative survey of the population aged 50+ in Ireland. Annual average PM2.5 concentrations at respondents' residential addresses over the period 1998-2014 are used to measure long-term exposure to ambient PM2.5. RESULTS: We find evidence of associations between long-term exposure to ambient PM2.5 and depression and anxiety. The measured associations are strong, and are comparable with effect sizes for variables such as sex. Effects are also evident at relatively low concentrations by international standards. However, we find no evidence of associations between long-term ambient particulate pollution and other indicators of mental health and well-being such as stress, worry and quality of life. CONCLUSIONS: The measured associations are strong, particularly considering the relatively low PM2.5 concentrations prevailing in Ireland compared to many other countries. While it is estimated that over 90 per cent of the world's population lives in areas with annual mean PM2.5 concentrations greater than 10 µg/m3, these results contribute to the increasing evidence that suggests that harmful effects can be detected at even low levels of air pollution.

A pilot study of the quality of care of atrial fibrillation in Irish general practice.

BACKGROUND: Worldwide, atrial fibrillation (AF) is the most common sustained cardiac arrhythmia in adults and poses a significant burden to patients, physicians, and healthcare systems. We developed a quality of care score based on the Atrial Fibrillation Better Care pathway recommended by the European Society of Cardiology and the European Heart Rhythm Association guidelines. This is a 14-point score that we have termed the MAGIC score(Management of Atrial Fibrillation in Integrated Care and General Practice). OBJECTIVE: The objective of this pilot study was to develop and test a quality of care score for patients with permanent AF in general practice. METHODS: An observational cross-sectional pilot study was undertaken. Proportionate sampling was used across 11 practices from the Ireland East practice-based research network. The GPs completed a report form on each patient by undertaking a retrospective chart review. Eleven practices participated with a total of 1855 patients with AF. We received data on 153 patients. RESULTS: The main findings were that no patient met all 14 guideline based recommendations. The mean MAGIC score was 11.3. Points were most commonly deducted because the creatinine clearance and HAS-BLED score were not recorded, and the patient was not on the correct dose of oral anti-coagulation. CONCLUSION: This study demonstrates the feasibility of using a quality of care score to measure the quality of AF management in general practice. This scoring system, which is based on internationally recognized quality of care markers, highlights key areas that can be targeted with quality improvement intervention.

Atrial fibrillation (AF) is the most common arrhythmia in the world. An arrhythmia is when your heart beats in a disorganized way with no pattern. AF is a serious health problem because this rhythm can lead to other heart problems, stroke, and even death. Even though it is common, we know that people with AF do not always receive the correct treatment and monitoring. Treatment aims to control the heart rate, rhythm and minimize blood clot formation. Treating patients according to recommended guidelines will improve their medical care and outcomes. We created a 14-point quality-of-care score based on international clinical practice guidelines. This project was done to check if this score was practical to use and if it showed any patterns in the quality of care being delivered. Eleven GP practices from the Southeast of Ireland participated and gave us information on 153 patients with AF. We assigned each chart a quality-of-care score based on the tool we developed. No chart scored 14 points (full marks). The most common reasons for points being deducted were not recording kidney function, bleeding risk, and the patients being on the wrong dose of medication. With this information, we can now move forward and try to improve care for these patients by targeting the highlighted deficits.

An updated scoping review of migrant health research in Ireland.

BACKGROUND: One in five people living in Ireland is a migrant. Understanding the distinctive health needs of this diverse population is essential to provide evidence-based, culturally sensitive primary care services. The aim of this review is to systematically examine changes in migrant health research in Ireland and to inform research, policy and practice in the field. METHODS: To update a 2017 scoping review of migrant health research in Ireland, we used Arksey and O'Malley's framework, updates by Colquhoun and Peters and the PRISMA-ScR from the Joanna Briggs Institute to search 10 databases covering May 2017 - March 2023. Findings were analysed using the World Health Organisation Strategy and Action Plan for Refugee and Migrant Health 2016-2023, which identifies 9 priority strategic areas (SA). Findings were compared with the 2017 review. RESULTS: 62 papers were identified. There has been an increase in studies over time from an average of five per year in the previous review to an average of 10 per year in this review. There is growing interest in research about SA1: Collaborative action on migrant health issues and SA2: Advocacy for the right to health of refugees and migrants - evidenced by an increase of 13% in this review. Similarly to 2017, the majority of papers align with three of the nine WHO Strategic Areas; SA3: Addressing the social determinants of health (24%), SA4: Achieving public health preparedness (29%) and SA5: Strengthening health systems (26%). The volume of research on SA6: Communicable diseases (11%) and SA7: Noncommunicable diseases (19%) remains stable however research on SA8: Health screening and assessment (5%) and SA9: Improving health information and communication (2%) remains low. CONCLUSIONS: The increase in the volume of research on migrant health in Ireland is notable. The analysis over time illuminates changes in the focus of research studies. Gaps in research about screening, assessment and health information warrant particular attention. It is also necessary to continue paying attention to areas of recent growth and stagnation for a balanced and comprehensive evidence base. Mobilising resources to continue this increase is needed for evidence-based policy and practice.

Men's Health in Northern Ireland: Why do we need a men's health policy?

Males accounted for half the United Kingdom population in 2021 yet they fail to be prioritised in health and social policies. As examining the health of males and females collectively falls short in accounting for the complexities associated with gendered health outcomes, male health should be considered as a separate policy issue. The island of Ireland has two jurisdictions, the Republic of Ireland and Northern Ireland (NI); however, only the former has implemented a men's health policy. As well as a policy vacuum within NI, few studies have comprehensively examined male health. To address this shortcoming, a narrative review of males' physical and mental health trends in NI is presented to determine the need for a men's health policy. A collation of secondary administrative data and survey data was conducted. The narrative review highlights the importance of utilising a holistic framework to understand men's health. Key findings include high male suicide rates and young males being more likely to report certain mental health problems. The study concludes that a male health policy is needed. To achieve this, a Health Impact Pyramid was developed, and it illustrates practical steps that can be taken to support decision-makers, service providers and individual males.

What explains regional variation in privately provided out-of-area residential placement costs for people with intellectual disability in Ireland?

BACKGROUND: Expenditure on residential placements for people with intellectual disability (ID) in Ireland is considerable and expected to increase. Despite this, there is limited evidence on the factors driving variation in privately provided 'out-of-area' residential placement costs, including across Community Health Organisations (CHOs)/regions. This is important to help inform the delivery of services at best value. METHODS: We analyse unit cost data from 2019 for a sample of 278 high-cost publicly funded privately provided out-of-area residential placements for people with ID in Ireland. We undertake univariate analysis of the relationship between costs and a wide range of variables using t-tests and one-way analysis of variance. We employ multivariable regression analysis to examine how raw differentials in unit costs across regions can be accounted for by individual-level characteristics. RESULTS: We estimate average unit costs of €264 170 per annum in our sample. The univariate analysis shows considerable variation in costs across a range of personal, disability, psychiatry/psychological, forensic issues, behaviour and supports and plans related variables. We also find wide variation in average unit costs across CHOs/regions (F = 4.58, P < 0.001), ranging from €213 380 to €331 880. The multivariable analysis shows that regional differences remain even after accounting for a wide range of individual characteristics that influence costs. CONCLUSIONS: Our analysis shows that while the majority of differences in costs across regions can be explained, there is potential for cost savings in the provision of high-cost publicly funded out-of-area residential placements in Ireland. Overall this can help to develop and implement a more sustainable disability residential funding model in a context of rising demand for services. It also has potential implications for the approach to procurement of services.

The approach to developing Ireland's first national health protection strategy and lessons learnt, December 2021 to October 2022.

The COVID-19 pandemic highlighted the importance of strengthening health protection worldwide. To address this as a public health priority in Ireland, between December 2021 and October 2022 the first national Health Protection Strategy (2022-2027) for the Irish Health Service Executive (HSE) was developed. We describe the approach taken to develop a first national health protection strategy for Ireland, and highlight the key lessons learned. Key steps in strategy formation included detailed stakeholder analysis, exploration of the context for the strategy and development of a comprehensive consultation plan. Two stakeholder consultation workshops were held. The first focused on defining strategic vision, aim and objectives, the second verified objectives and identified enablers. A subsequent e-consultation invited feedback from wider stakeholders. The published strategy outlines 10 strategic objectives and 11 enablers. Key lessons identified from the strategy development process include the importance of clear leadership and oversight, the value of identifying the context for change, ensuring adequate consultation planning, taking a multidisciplinary approach with strong stakeholder engagement and the need to maintain a strategic perspective. Lessons from our experience can support colleagues internationally to strategically set out their priorities for health protection beyond COVID-19.

Stakeholder perceptions of cervical screening accessibility and attendance in Ireland: a qualitative study.

Organized cervical screening programmes are commonplace in high-income countries. To provide an equitable cervical screening service, it is important to understand who is and is not attending screening and why. Promotion of screening and service improvement is not possible without recognition and identification of the barriers and needs of communities that are less engaged with screening. This study explored stakeholder perceptions of cervical screening attendance and accessibility in Ireland. Semi-structured interviews were conducted with 12 healthcare professionals, policymakers and academics. Interviews were conducted online in 2022. Reflexive thematic analysis was used inductively to generate themes, supported by NVivo. Three themes were developed: (i) getting the right information out the right way, (ii) acceptability and accessibility of screening and (iii) trying to identify and reach the non-attenders. Participants felt public knowledge of cervical screening and human papilloma virus was low and communication strategies were not adequate. Individual, cultural, structural and service-level factors influenced the accessibility and acceptability of screening. Identifying and reaching non-attenders was considered challenging and community outreach could support those less likely to attend screening. Stakeholder perspectives were valuable in understanding the complexities of screening accessibility and attendance from individual to service-level factors. Cultural competency training, inclusive language and visual cues in waiting rooms would support engagement with some populations who may be hesitant to attend screening. Collaboration with community organizations has opportunities to promote screening and understand the needs of those less likely to attend screening.

The woman is the active agent: General practitioners and the agentive displacement of abortion in Ireland.

After the legalization of abortion in 2018, Ireland needed clinicians to become abortion providers and make this political win a medical reality. Yet Irish doctors had next-to-no training in abortion care, and barriers ranging from stigma to economic pressures in the healthcare system impacted doctors' desire to volunteer. How did hundreds of Irish doctors make the shift from family doctor to abortion provider? Drawing on ethnographic research conducted between 2017 and 2020, this article explores the process by which Irish general practitioners became abortion providers, attending to the material impact of medical technologies on that journey. Drawing from medical anthropologists who have examined similar themes of agency, pharmaceuticals, and medico-legal frameworks within the topic of assisted dying, I build on Anita Hannig's idea of "agentive displacement" to frame the productive impact of abortion pills on this transition.

Biochemical profiling and antioxidant activity analysis of commercially relevant seaweeds from northwest Europe.

BACKGROUND: The drive towards ensuring the sustainability of bioresources has been linked with better valorising primary materials and developing biorefinery pipelines. Seaweeds constitute valuable coastal resources with applications in the bioenergy, biofertiliser, nutrition, pharmaceutical and cosmetic sectors. Owing to the various sought-after metabolites they possess, several seaweed species are commercially exploited throughout Western Europe, including Ireland. Here, four commercially relevant brown (Fucus serratus and Fucus vesiculosus) and red (Chondrus crispus and Mastocarpus stellatus) seaweed species were sampled during a spring tide in July 2021 on moderately exposed shores across three coastal regions in the west of Ireland. RESULTS: Significant regional differences were identified when specimens were analysed for carbohydrates (max. 80.3 µg glucose eq mg-1 DW), proteins (max. 431.3 µg BSA eq. mg-1 DW), lipids (max. 158.6 mg g-1 DW), pigment signature and antioxidant potential. Protein content for F. serratus recorded a twofold difference between northern and southern specimens. The antioxidant potential of F. vesiculosus and M. stellatus returned greater activity compared to F. serratus and C. crispus, respectively. Multivariate analysis showed a clear latitudinal pattern across the three western coastal regions (north, west and south) for both F. vesiculosus and F. serratus. CONCLUSION: F. vesiculosus thalli from the northwest were richer in pigment content while the F. serratus thalli from the northwest were richer in antioxidants. Such biogeographic patterns in the biochemical make-up of seaweeds need consideration for the development of regional integrated aquaculture systems and the optimisation of the biomass content for targeted downstream applications. © 2024 Society of Chemical Industry.

'There's no waiting list, just press play': listeners' experiences of mental-health-related podcasts.

INTRODUCTION: The activity of podcasting has increased exponentially but little is known about the qualitative listener experiences of podcasts related to mental health. The aim of this study was to understand what listeners of mental health podcasts obtain from this medium. Participants were asked questions relating to mental health literacy, stigma and help-seeking behaviour. METHODS: The study gathered data, via an online survey (n=722). This article reports on the responses to open-ended questions: 'What do you take away from listening to mental health-related podcasts? What do you learn about yourself (or a loved one)? What do you find most useful about listening to mental health-related podcasts?' Inductive thematic analysis was utilised. RESULTS: Thematic analysis produced five core themes: accessibility, mental health literacy, potential pitfalls, reassurance and lived experiences. Accessibility of material and discussions featuring professionals and people with lived experience were reported key highlights. CONCLUSION: Results indicate that podcasts influence the development of mental health literacy, reduce stigma and increase help-seeking. Given the challenges with service access in underserved populations, there is a potential role for the use of podcasts in rural regions.

Deinstitutionalisation and the move to community care: comparing the changing dimensions of mental healthcare after 1922 in the Republic of Ireland and England.

The advent of deinstitutionalisation and the introduction of community care in the latter part of the twentieth century have revolutionised mental-health service provision across Europe, although implementation, timing and services have varied widely in different countries. This article compares the changing dimensions of mental-health provision in post-independence Ireland with that in England, and will shed light on the current state of mental healthcare in both countries. The article calls for more research into the impact of deinstitutionalisation, such as the challenges faced in the community for those in need of continuing care.

Adeno-Associated Virus 2 and Human Adenovirus F41 in Wastewater during Outbreak of Severe Acute Hepatitis in Children, Ireland.

During April-July 2022, outbreaks of severe acute hepatitis of unknown etiology (SAHUE) were reported in 35 countries. Five percent of cases required liver transplantation, and 22 patients died. Viral metagenomic studies of clinical samples from SAHUE cases showed a correlation with human adenovirus F type 41 (HAdV-F41) and adeno-associated virus type 2 (AAV2). To explore the association between those DNA viruses and SAHUE in children in Ireland, we quantified HAdV-F41 and AAV2 in samples collected from a wastewater treatment plant serving 40% of Ireland's population. We noted a high correlation between HAdV-F41 and AAV2 circulation in the community and SAHUE clinical cases. Next-generation sequencing of the adenovirus hexon in wastewater demonstrated HAdV-F41 was the predominant HAdV type circulating. Our environmental analysis showed increased HAdV-F41 and AAV2 prevalence in the community during the SAHUE outbreak. Our findings highlight how wastewater sampling could aid in surveillance for respiratory adenovirus species.

Congenital hypothyroidism in Northern Ireland: 40 years' experience of national screening programme.

OBJECTIVE: The incidence of congenital hypothyroidism (CHT) has progressively increased in several regions around the world but has yet to be evaluated in Northern Ireland (NI). CHT screening programme was introduced in NI in 1980 and has had a relatively unchanged protocol since its inception. The purpose of the study was to evaluate the incidence of CHT in NI from 1981 to 2020 and to explore possible contributing factors to any changes seen over the 40-year period. DESIGN: This was a retrospective database review of children diagnosed with CHT in NI between 1981 and 2020. Data was collected from the patients' medical (paper and electronic) records, including epidemiological, clinical, laboratory, and radiological features as well as outcomes at 3 years. RESULTS: Of 800,404 new-borns who were screened for CHT in NI between January 1981 and March 2020, 471 were diagnosed with CHT. There was a steady and significant increase in incidence of CHT over time with an incidence of 26 cases per 100,000 livebirths in 1981 versus 71 cases per 100,000 in 2019 (p < .001). Of these 471, 77 new-borns (16%) were born preterm. The incidence of CHT was observed twice as much in female compared to male new-borns. Diagnostic imaging including radioisotope uptake and thyroid ultrasound scans were performed in 143 cases (30%). Of these, 101 (70%) cases had thyroid dysgenesis and 42 (30%) cases had thyroid dyshormonogenesis. There were 293 (62%) of 471 patients had confirmed permanent CHT, and 90 patients (19%) had transient CHT. Over that period at least 95% of the population were recorded as having United Kingdom/Ireland as country of birth. CONCLUSION: Our findings demonstrate a nearly tripling of the CHT incidence observed over the last 40 years. This is against a background of a relatively stable population demographics. Future research should focus on the underlying cause(s) of this condition which may include changing environmental exposures in utero.

Long-term outcome collection after hip fracture in Ireland: a systematic review of traditional and grey literature.

This review aimed to describe the methods and results from recent Irish research about post-acute hip fracture outcomes. Meta-analyses estimate the 30-day and 1-year mortality rate at 5% and 24% respectively. There is a need for standardised recommendations about which data should be recorded to aid national and international comparisons. PURPOSE: Over 3700 older adults experience hip fracture in Ireland annually. The Irish Hip Fracture Database national audit records acute hospital data but lacks longer-term outcomes. This systematic review aimed to summarise and appraise recent Irish studies that collected long-term hip fracture outcomes and to generate pooled estimates where appropriate. METHODS: Electronic databases and grey literature were searched in April 2022 for articles, abstracts, and theses published from 2005 to 2022. Eligible studies were appraised by two authors and outcome collection details summarised. Meta-analyses of studies with common outcomes were conducted where the sample was generalisable to the broad hip fracture population. RESULTS: In total, 84 studies were identified from 20 clinical sites. Outcomes commonly recorded were mortality (n = 48 studies; 57%), function (n = 24; 29%), residence (n = 20; 24%), bone-related outcomes (n = 20; 24%), and mobility (n = 17; 20%). One year post-fracture was the most frequent time point, and patient telephone contact was the most common collection method used. Most studies did not report follow-up rates. Two meta-analyses were performed. The pooled estimate for one-year mortality was 24.2% (95% CI = 19.1-29.8%, I2 = 93.8%, n = 12 studies, n = 4220 patients), and for 30-day mortality was 4.7% (95% CI = 3.6-5.9%, I2 = 31.3%, n = 7 studies, n = 2092 patients). Reports of non-mortality outcomes were deemed inappropriate for meta-analysis. CONCLUSION: Hip fracture long-term outcomes collected in Irish research are broadly in line with international recommendations. Heterogeneity of measures and poor reporting of methods and findings limits collation of results. Recommendations for standard outcome definitions nationally are warranted. Further research should explore the feasibility of recording long-term outcomes during routine hip fracture care in Ireland to enhance national audit.

Bayesian areal disaggregation regression to predict wildlife distribution and relative density with low-resolution data.

For species of conservation concern and human-wildlife conflict, it is imperative that spatial population data be available to design adaptive-management strategies and be prepared to meet challenges such as land use and climate change, disease outbreaks, and invasive species spread. This can be difficult, perhaps impossible, if spatially explicit wildlife data are not available. Low-resolution areal counts, however, are common in wildlife monitoring, that is, the number of animals reported for a region, usually corresponding to administrative subdivisions, for example, region, province, county, departments, or cantons. Bayesian areal disaggregation regression is a solution to exploit areal counts and provide conservation biologists with high-resolution species distribution predictive models. This method originated in epidemiology but lacks experimentation in ecology. It provides a plethora of applications to change the way we collect and analyze data for wildlife populations. Based on high-resolution environmental rasters, the disaggregation method disaggregates the number of individuals observed in a region and distributes them at the pixel level (e.g., 5 × 5 km or finer resolution), thereby converting low-resolution data into a high-resolution distribution and indices of relative density. In our demonstrative study, we disaggregated areal count data from hunting bag returns to disentangle the changing distribution and population dynamics of three deer species (red, sika, and fallow) in Ireland from 2000 to 2018. We show an application of the Bayesian areal disaggregation regression method and document marked increases in relative population density and extensive range expansion for each of the three deer species across Ireland. We challenged our disaggregated model predictions by correlating them with independent deer surveys carried out in field sites and alternative deer distribution models built using presence-only and presence-absence data. Finding a high correlation with both independent data sets, we highlighted the ability of Bayesian areal disaggregation regression to accurately capture fine-scale spatial patterns of animal distribution. This study uncovers new scenarios for wildlife managers and conservation biologists to reliably use regional count data disregarded so far in species distribution modeling. Thus, it represents a step forward in our ability to monitor wildlife population and meet challenges in our changing world.

Resource competition drives an invasion-replacement event among shrew species on an island.

Invasive mammals are responsible for the majority of native species extinctions on islands. While most of these extinction events will be due to novel interactions between species (e.g. exotic predators and naive prey), it is more unusual to find incidences where a newly invasive species causes the decline/extinction of a native species on an island when they normally coexist elsewhere in their overlapping mainland ranges. We investigated if resource competition between two insectivorous small mammals was playing a significant role in the rapid replacement of the native pygmy shrew Sorex minutus in the presence of the recently invading greater white-toothed shrew Crocidura russula on the island of Ireland. We used DNA metabarcoding of gut contents from >300 individuals of both species to determine each species' diet and measured the body size (weight and length) during different stages of the invasion in Ireland (before, during and after the species come into contact with one another) and on a French island where both species have long coexisted (acting as a natural 'control' site). Dietary composition, niche width and overlap and body size were compared in these different stages. The body size of the invasive C. russula and composition of its diet changes between when it first invades an area and after it becomes established. During the initial stages of the invasion, individual shrews are larger and consume larger sized invertebrate prey species. During later stages of the invasion, C. russula switches to consuming smaller prey taxa that are more essential for the native species. As a result, the level of interspecific dietary overlap increases from between 11% and 14% when they first come into contact with each other to between 39% and 46% after the invasion. Here we show that an invasive species can quickly alter its dietary niche in a new environment, ultimately causing the replacement of a native species. In addition, the invasive shrew could also be potentially exhausting local resources of larger invertebrate species. These subsequent changes in terrestrial invertebrate communities could have severe impacts further downstream on ecosystem functioning and services.

Estimated mortality of the highly pathogenic avian influenza pandemic on northern gannets (Morus bassanus) in southwest Ireland.

The 2022 highly pathogenic avian influenza (HPAI) outbreak that occurred in many European countries affected several seabird species. Among them, northern gannets (Morus bassanus) were particularly impacted. We conducted aerial surveys in waters around the two largest gannet colonies in southwest Ireland (Little Skellig and Bull Rock, together representing 87% of the national population) in September 2022. During surveys dead and alive northern gannets were counted on survey effort. A total of 184 dead gannets were recorded on survey effort, representing 3.74% of the total number of gannets recorded. We estimated the abundance of dead gannets in the surveyed area at 1526 (95% confidence intervals (CIs) 1450-1605) individuals. The percentage of dead gannets observed was used to estimate a minimum local population mortality of 3126 (95% CIs 2993-3260) individuals across both colonies. Aerial surveys provided key information on gannet mortality from HPAI at sea. The study provides the first estimate of gannet mortality in the two largest gannetries in Ireland.

Cost-Effectiveness of First-Line Pembrolizumab Monotherapy Versus Chemotherapy in High Programmed Death-Ligand 1 Advanced Non-Small Cell Lung Cancer in the Irish Healthcare Setting.

OBJECTIVES: This study aimed to assess the cost-effectiveness of pembrolizumab monotherapy in the first-line treatment of advanced non-small cell lung cancer (NSCLC) in adults whose tumors expressed programmed death-ligand 1 (PD-L1) with a tumor proportion score (TPS) ≥ 50% in the Irish healthcare setting. METHODS: Effectiveness inputs were derived from the 5-year analysis of KEYNOTE-024 phase III clinical trial. The intervention was pembrolizumab monotherapy; the comparator was a weighted average of the 5 chemotherapy regimens from the trial. The population included those with previously untreated advanced PD-L1 TPS ≥ 50% NSCLC. A de novo partitioned survival model was developed. Survival modeling was done using Bayesian model averaging on fitted parametric functions. Costs included drug acquisition, treatment initiation, administration and monitoring, adverse events, subsequent treatments, and terminal care. Costs and health state utilities were sourced from the literature and Irish sources. The model had a 20-year time horizon. The perspective taken was the Health Service Executive. A 4% discount rate was applied. Outcomes were expressed as an incremental cost-effectiveness ratio (ICER), measured in terms of incremental costs per quality-adjusted life-year (QALY). Probabilistic sensitivity analysis and 1-way sensitivity analyses were conducted. RESULTS: The model estimated a base case ICER of €54 237 per QALY. The probabilistic sensitivity analysis estimated an average ICER of €54 568 per QALY and a 11% probability of cost-effectiveness at the Irish cost-effectiveness threshold of €45 000 per QALY. CONCLUSION: At the current list price, first-line pembrolizumab monotherapy is not considered cost-effective for the treatment of advanced PD-L1 TPS ≥ 50% NSCLC in the Irish healthcare setting.

Vitamin D: determinants of status, indications for testing and knowledge in a convenience sample of Irish adults.

Vitamin D deficiency is common in Irish adults, though there is limited research on its determinants, knowledge of vitamin D or indications for testing. We aimed to explore the determinants of vitamin D status in adults and examine knowledge and reasons for testing. The study population comprised adults who had serum 25-hydroxyvitamin D tested by general practitioners request at a Dublin Hospital in 2020. Questionnaires detailing dietary intake, sun exposure, ethnicity, biophysical factors and vitamin D knowledge were sent to a sample stratified by age, sex and vitamin D status. In total, there were 383 participants, mean age 56·0 (sd 16·6) years. Wintertime deficiency disproportionally affected non-white v. white (60 % v. 24 %, P < 0·001). The greatest predictors of deficiency were low vitamin D intake (< 10 µg/d) (P < 0·001) and non-white ethnicity (P = 0·006), followed by sun avoidance (P = 0·022). It was also more prevalent in those with lower body exposure when outdoors. The majority (86 %) identified vitamin D as important for bone health. However, 40 % were tested for non-clinical indications and half were not aware of the recommended daily allowance (RDA). Low vitamin D intake was the most important determinant of deficiency, but ethnicity and sun exposure habits were also significant predictors. The majority had no clear indication for testing and were not aware of the RDA. Public health policies to improve knowledge and vitamin D intake, especially for those of non-white ethnicity and with reduced sun exposure, should be considered.

Where Are We Now with Liver Transplantation in Neuroendocrine Neoplasms? The Place of Liver Transplantation for Grades 1 and 2 Well-Differentiated Unresectable Liver Metastatic Neuroendocrine Tumours.

PURPOSE OF REVIEW: This review outlines the role of liver transplantation in selected patients with unresectable neuroendocrine tumour liver metastases. It discusses the international consensus on eligibility criteria and outlines the efforts taking place in the UK and Ireland to develop effective national liver transplant programmes for neuroendocrine tumour patients. RECENT FINDINGS: In the early history of liver transplantation, indications included cancer metastases to the liver as well as primaries of liver origin. Often, liver transplantation was a salvage procedure. The early results were disappointing, including in patients with neuroendocrine tumours. These data discouraged the widespread adoption of liver transplantation for neuroendocrine tumour liver metastases (NET LM). A few centres persisted in performing liver transplantation for patients with NET LM and in determining parameters predictive of good outcomes. Their work has provided evidence for benefit of liver transplantation in a selected group of patients with NET LM. Liver transplantation for NET LM is now accepted as a valid indication by many professional bodies, including the European Neuroendocrine Tumour Society (ENETS) and the United Network for Organ Sharing (UNOS). It is nevertheless rarely utilised. The UK and the Republic of Ireland are commencing a pilot programme of liver transplantation in selected patients. This programme will help develop the expertise and infrastructure to make liver transplantation for NET LM a routine procedure.
