Large-scale plasma proteomics comparisons through genetics and disease associations.

High-throughput proteomics platforms measuring thousands of proteins in plasma combined with genomic and phenotypic information have the power to bridge the gap between the genome and diseases. Here we performed association studies of Olink Explore 3072 data generated by the UK Biobank Pharma Proteomics Project1 on plasma samples from more than 50,000 UK Biobank participants with phenotypic and genotypic data, stratifying on British or Irish, African and South Asian ancestries. We compared the results with those of a SomaScan v4 study on plasma from 36,000 Icelandic people2, for 1,514 of whom Olink data were also available. We found modest correlation between the two platforms. Although cis protein quantitative trait loci were detected for a similar absolute number of assays on the two platforms (2,101 on Olink versus 2,120 on SomaScan), the proportion of assays with such supporting evidence for assay performance was higher on the Olink platform (72% versus 43%). A considerable number of proteins had genomic associations that differed between the platforms. We provide examples where differences between platforms may influence conclusions drawn from the integration of protein levels with the study of diseases. We demonstrate how leveraging the diverse ancestries of participants in the UK Biobank helps to detect novel associations and refine genomic location. Our results show the value of the information provided by the two most commonly used high-throughput proteomics platforms and demonstrate the differences between them that at times provides useful complementarity.

The sequences of 150,119 genomes in the UK Biobank.

Detailed knowledge of how diversity in the sequence of the human genome affects phenotypic diversity depends on a comprehensive and reliable characterization of both sequences and phenotypic variation. Over the past decade, insights into this relationship have been obtained from whole-exome sequencing or whole-genome sequencing of large cohorts with rich phenotypic data1,2. Here we describe the analysis of whole-genome sequencing of 150,119 individuals from the UK Biobank3. This constitutes a set of high-quality variants, including 585,040,410 single-nucleotide polymorphisms, representing 7.0% of all possible human single-nucleotide polymorphisms, and 58,707,036 indels. This large set of variants allows us to characterize selection based on sequence variation within a population through a depletion rank score of windows along the genome. Depletion rank analysis shows that coding exons represent a small fraction of regions in the genome subject to strong sequence conservation. We define three cohorts within the UK Biobank: a large British Irish cohort, a smaller African cohort and a South Asian cohort. A haplotype reference panel is provided that allows reliable imputation of most variants carried by three or more sequenced individuals. We identified 895,055 structural variants and 2,536,688 microsatellites, groups of variants typically excluded from large-scale whole-genome sequencing studies. Using this formidable new resource, we provide several examples of trait associations for rare variants with large effects not found previously through studies based on whole-exome sequencing and/or imputation.

Estimated glomerular filtration rate slopes on tenofovir alafenamide.

OBJECTIVES: The aim of the study was to analyse and compare estimated glomerular filtration rate (eGFR) slopes during exposure to tenofovir disoproxil fumarate (TDF) and tenofovir alafenamide (TAF) in individuals who initiated TAF, regardless of prior regimen, before October 2016. METHODS: An observational cohort study was conducted at 11 clinics in the UK and Ireland. Mixed effects models with random intercept and time terms fitted were used to generate and compare eGFR slopes while participants were exposed to TDF and TAF, with adjustment for age, eGFR at TDF/TAF initiation, gender, ethnicity, and time-updated CD4 cell count and HIV RNA measurements. RESULTS: Data were available for 357 subjects (median age 50 years; 80% male; 82% white/other ethnicity; 51% men who have sex with men; median nadir CD4 count 216 cells/µL). The median duration of exposure to TAF was 2.0 (interquartile range 1.6, 2.3) years. At TAF initiation, the median CD4 count was 557 cells/µL, the median eGFR was 80 mL/min/1.73 m2, and 86% had suppressed HIV infection. The mean adjusted eGFR slope during TDF and TAF exposure was -2.08 [95% confidence interval (CI) -2.24, -1.92] and 1.18 (95% CI 0.20, 1.52) mL/min/1.73 m2/year, respectively (P < 0.001). Individuals who experienced rapid eGFR decline (> 3 or 5 mL/min/1.73 m2/year) while receiving TDF experienced significant eGFR recovery while on TAF (P < 0.001). CONCLUSIONS: Significant improvement in eGFR slope was observed in patients who switched from TDF- to TAF-containing antiretroviral regimens. These data provide further support for the renal safety of TAF, and for switching those who experience progressive worsening of renal function from TDF to TAF.

Culturally Sensitive Care in the Neonatal Setting to Infants Born to Parents From the Traveler Community: An Exploration of the Perspectives of Neonatal Staff.

Introduction: Culture and traditions influence people's health beliefs and these influence their actions and behaviors to prevent ill health and promote health and well-being. This qualitative study explored nurses'/midwives perspectives of culturally sensitive care in a neonatal setting to infants born to parents from the Traveler community. Method: A descriptive qualitative approach was used to interview 10 nurses/midwives from a neonatal unit in Ireland. Data were analyzed using Burnard's framework. Results: Themes identified were as follows: (a) barriers to breastfeeding for women from the Traveler community, (b) cultural issues affecting care provision to Traveler families in the neonatal unit, and (c) concerns of neonatal staff for infants born within the Traveler community. Discussion: The culture of the Traveler group was recognized as a major influence on decision making and interactions within the neonatal unit. Strategies are identified that could enhance the care of this group and the care of other ethnic groups.

Exposure to intergroup conspiracy theories promotes prejudice which spreads across groups.

This research experimentally examined the effects of exposure to intergroup conspiracy theories on prejudice and discrimination. Study 1 (N = 166) demonstrated that exposure to conspiracy theories concerning immigrants to Britain from the European Union (vs. anti-conspiracy material or a control) exacerbated prejudice towards this group. Study 2 (N = 173) found the same effect in a different intergroup context - exposure to conspiracy theories about Jewish people (vs. anti-conspiracy material or a control) increased prejudice towards this group and reduced participants' willingness to vote for a Jewish political candidate. Finally, Study 3 (N = 114) demonstrated that exposure to conspiracy theories about Jewish people not only increased prejudice towards this group but was indirectly associated with increased prejudice towards a number of secondary outgroups (e.g., Asians, Arabs, Americans, Irish, Australians). The current research suggests that conspiracy theories may have potentially damaging and widespread consequences for intergroup relations.

'Everything was just getting worse and worse': deteriorating job quality as a driver of doctor emigration from Ireland.

BACKGROUND: Medicine is a high-status, high-skill occupation which has traditionally provided access to good quality jobs and relatively high salaries. In Ireland, historic underfunding combined with austerity-related cutbacks has negatively impacted job quality to the extent that hospital medical jobs have begun to resemble extreme jobs. Extreme jobs combine components of a good quality job-high pay, high job control, challenging demands, with those of a low-quality job-long working hours, heavy workloads. Deteriorating job quality and the normalisation of extreme working is driving doctor emigration from Ireland and deterring return. METHODS: Semi-structured qualitative interviews were conducted with 40 Irish emigrant doctors in Australia who had emigrated from Ireland since 2008. Interviews were held in July-August 2018. RESULTS: Respondents reflected on their experiences of working in the Irish health system, describing hospital workplaces that were understaffed, overstretched and within which extreme working had become normalised, particularly in relation to long working hours, fast working pace, doing more with less and fighting a climate of negativity. Drawing on Hirschman's work on exit, voice and loyalty (1970), the authors consider doctor emigration as exit and present respondent experiences of voice prior to emigration. Only 14/40 respondent emigrant doctors intend to return to work in Ireland. DISCUSSION: The deterioration in medical job quality and the normalisation of extreme working is a key driver of doctor emigration from Ireland, and deterring return. Irish trained hospital doctors emigrate to access good quality jobs in Australia and are increasingly likely to remain abroad once they have secured them. To improve doctor retention, health systems and employers must mitigate a gainst the emergence of extreme work in healthcare. Employee voice (about working conditions, about patient safety, etc.) should be encouraged and used to inform health system improvement and to mitigate exit.

Near the Knuckle : How Evolutionary Logic Helps Explain Irish Traveller Bare-Knuckle Contests.

Irish Travellers constitute a pre-demographic-shift population living among a post-demographic-shift one. Their socio-medico profile identifies them as largely on fast life-history trajectories. In addition, they are strongly religious (typically using no contraception), highly sexually behaviorally dimorphic, with strong traditions of male-male competition (bare-knuckle fighting) and quasi-symbolic bride capture ("grabbing"). Their male-male competitions thus allow for the comparative testing of a number of interesting theories pertaining to the nature and function of types of violence in society. As a pilot study, we used expert raters (some naive to the hypotheses) to analyze a number of real-life bare-knuckle competitions in terms of the support said spectacles offered to theories of this sort of violence as reinforcing ideas of antisociality, hierarchical promotion, intersexual signaling, or maintenance of within-group equality. We found good evidence to support theories of within-group, prosocial hierarchical functions for these contests. Limitations and implications for future research, such as direct measurement of fitness, are discussed.

Tracking the leavers: towards a better understanding of doctor migration from Ireland to Australia 2008-2018.

BACKGROUND: The recession of 2008 triggered large-scale emigration from Ireland. Australia emerged as a popular destination for Irish emigrants and for Irish-trained doctors. This paper illustrates the impact that such an external shock can have on the medical workforce and demonstrates how cross-national data sharing can assist the source country to better understand doctor emigration trends. METHOD: This study draws on Australian immigration, registration and census data to highlight doctor migration flows from Ireland to Australia, 2008-2018. FINDINGS: General population migration from Ireland to Australia increased following the 2008 recession, peaked between 2011 and 2013 before returning to pre-2008 levels by 2014, in line with the general economic recovery in Ireland. Doctor emigration from Ireland to Australia did not follow the same pattern, but rather increased in 2008 and increased year on year since 2014. In 2018, 326 Irish doctors obtained working visas for Australia. That doctor migration is out of sync with general economic conditions in Ireland and with wider migration patterns indicates that it is influenced by factors other than evolving economic conditions in Ireland, perhaps factors relating to the health system. DISCUSSION: Doctor emigration from Ireland to Australia has not decreased in line with improved economic conditions in Ireland, indicating that other factors are driving and sustaining doctor emigration. This paper considers some of these factors. Largescale doctor emigration has significant implications for the Irish health system; representing a brain drain of talent, generating a need for replacement migration and a high dependence on internationally trained doctors. This paper illustrates how source countries, such as Ireland, can use destination country data to inform an evidence-based policy response to doctor emigration.

A Comparative Sociology of Gypsy Traveller Health in the UK.

This paper presents findings from a series of health-related studies undertaken between 2012 and 2017 with Romany Gypsies and Irish Travellers living in different locations and in various forms of accommodation in southern England. These set out to develop a sociological understanding of the factors impacting on the health and wellbeing of members of those communities and to consider the extent health status is shaped by ethno-cultural and/or socioeconomic factors, and the interplay and direction of causal processes between them. The relative influences of cultural and structural factors in generating health inequalities have important implications for engaging marginalised populations in health services and preventative programmes. This paper will present survey and qualitative data on Gypsies' and Travellers' health beliefs and practices to understand how those beliefs and practices have developed in different social contexts as responses to deeper social mechanisms, and share commonalities with other marginalised and excluded social groups. In policy terms this indicates the need for health interventions that are applied proportionate to the level of disadvantage experienced thus ensuring equality and fairness while accounting for diversity and difference.

Learning about midwifery in another country from a distance: Evaluation of a virtual classroom learning session.

BACKGROUND: Studying abroad promotes cultural awareness and understanding of different healthcare settings and practices but family or financial constraints prevent some students from taking advantage of these opportunities. We developed a virtual classroom learning session to give Danish and Irish midwifery students an opportunity to explore midwifery and maternity care in another country. OBJECTIVES: To evaluate the content of midwifery students' chat room discussions about the differences in maternity and midwifery care during an international online learning session, and their opinions of the session. PARTICIPANTS: 27 Danish and 37 Irish undergraduate direct entry midwifery students. METHODS: Content analysis of students' chat room discussions and post-session survey. FINDINGS: Students engaged enthusiastically in the chat room discussions throughout the session. Almost all of the interactivity was between students themselves, and questions raised by students from one country were answered by students in the other country. Discussions centred on the lecture content, rates of interventions and birth outcomes, but developed into broader issues relating to one-to-one midwifery care during labour, factors that facilitate normal birth, national data availability, staffing levels, and financial and cultural aspects of having children at earlier or later ages. In the survey, students described the session as awakening curiosity and a fun way to learn. They found it 'cool' to talk with real students from another country, a memorable way of discussing differences between the two maternity care systems and expanding knowledge. Negative comments related to technological problems. CONCLUSION: An international virtual classroom learning session can give midwifery students insights into midwifery elsewhere, stimulate curiosity and be an engaging way to learn. Our students' experiences show that it can offer a real, engaging and positive learning experience and enrich students' knowledge of cultural differences.

Experience of skin disease and relationships with healthcare providers: a qualitative study of Traveller women in Ireland.

BACKGROUND: Significant health disparities exist between members of the Travelling community and those of the general population. Barriers to Traveller engagement with health services include the experience or perception of discrimination, and cultural and health literacy barriers. Experience of skin disease and interactions with healthcare providers has not been widely explored in this ethnic minority. The formation of positive relationships between the Travelling community and healthcare providers is important in the promotion of treatment adherence and improving health outcomes. OBJECTIVES: To investigate Travellers' experience of skin disease and their relationships with healthcare providers. METHODS: Focus groups were conducted with a purposive sample of female members of the Irish Travelling community with experience of skin health issues, between January 2018 and April 2018. Three focus groups were conducted at three separate locations with 10 participants in each group. Themes were identified from the focus group transcripts using an inductive thematic analysis framework. RESULTS: Emergent themes surrounding relationships between Travellers and healthcare providers included health literacy, discrimination, information inconsistency, trust and communication. Factors that were valued in the creation of positive relationships included an appreciation of varying degrees of health literacy, the provision of sufficient information tailored to an individual's needs and a demonstration of cultural competence. CONCLUSIONS: Dermatologists are well placed to provide practical, customized, treatment guidance and engage patients while integrating their culturally based beliefs.

Clinical epidemiology of familial sarcoidosis: A systematic literature review.

INTRODUCTION: Although the presence of familial sarcoidosis has been confirmed, clinical and epidemiological data on its characteristics are scattered and sometimes paradoxical. The objective of this review is to assess what is known on the clinical epidemiology of familial sarcoidosis, by combining data from early case reports with recent population based data; aiming to support in clinical decision making and providing information to patients. METHOD: A systematic review of the literature in PubMed was done and 27 studies with clinical or epidemiological data on familial sarcoidosis, published between 1947 and 2017, were included. RESULTS: The pooled prevalence proportion of familial sarcoidosis, based on twelve study populations, was 9.5% (CI 4.6-16.1), highest in French, African American, Dutch and Irish patients. A heritability of 60-70% was estimated in diverse studies. Relative types and relationships most often reported in familial sarcoidosis were siblings and mother-child relationships. Familial risk is heterogeneous. In African Americans specific environmental factors have been associated with familial sarcoidosis (OR between 1.5 and 3.2). European American and African American subjects had different relative risks for first degree familial relationships (OR of 16.6 vs 3.1) and relative risk differed between relative types. Clinical findings in familial sarcoidosis are still obscure. CONCLUSIONS: Prevalence of familial sarcoidosis is high in specific study populations from countries worldwide. The estimated heritability of 60-70%, suggests a shared determinant, and the heterogeneous familial risk, associated with both genetic and environmental factors. Familial relative risks and clinical phenotypes may differ between ethnic groups and relative types, but require further study.

Investigating ethnic variations in reporting of psychotic symptoms: a multiple-group confirmatory factor analysis of the Psychosis Screening Questionnaire.

BACKGROUND: Epidemiological evidence suggests risk for psychosis varies with ethnicity in Western countries. However, there is little evidence to date on the cross-cultural validity of screening instruments used for such comparisons. METHODS: Combining two existing UK population-based cohorts, we examined risk for reporting psychotic symptoms across White British (n = 3467), White Irish (n = 851), Caribbean (n = 1899), Indian (n = 2590), Pakistani (n = 1956) and Bangladeshi groups (n = 1248). We assessed the psychometric properties of the Psychosis Screening Questionnaire (PSQ) with a multiple-group confirmatory factor analysis, assessing the equivalence of factor loadings, response thresholds and residual variances in an analysis of measurement non-invariance. RESULTS: Compared with prevalence among British Whites (5.4%), the prevalence of self-reported psychotic symptoms was greater in the Caribbean group (12.7%, adjusted OR = 2.38 [95% CI 1.84-3.07]). Prevalence was also increased among Pakistani individuals (8.3%, adjusted OR = 1.36 [1.01-1.84]) although this difference was driven by a greater likelihood of reporting paranoid symptoms. PSQ items for thought interference, strange experience and hallucination were measured in equivalent ways across ethnic groups. However, our measurement models suggested that paranoid symptoms were measured less reliably among ethnic minorities than among British Whites and appeared to exaggerate latent differences between Pakistani and White British groups when measurement non-invariance was not accounted for. CONCLUSIONS: Notwithstanding evidence for measurement non-invariance, the greater risk for reporting psychotic symptoms among Caribbean individuals is unlikely to be an artefact of measurement. Greater residual variance in the recording of paranoid symptoms among ethnic minority respondents warrants caution in using this item to investigate ethnic variation in psychosis risk.

Ethnic differences in women's use of mental health services: do social networks play a role? Findings from a national survey.

OBJECTIVES: The reasons for ethnic differences in women's mental health service use in England remain unclear. The aims of this study were to ascertain: ethnic differences in women's usage of mental health services, if social networks are independently associated with service use, and if the association between women's social networks and service use varies between ethnic groups. DESIGN: Logistic regression modelling of nationally representative data from the Ethnic Minority Psychiatric Illness Rates in the Community (EMPIRIC) survey conducted in England. The analytic sample (2260 women, aged 16-74 years) was drawn from the representative subsample of 2340 women in EMPIRIC for whom data on mental health services, and social networks were available. RESULTS: Pakistani and Bangladeshi women were less likely than White women to have used mental health services (Pakistani OR = 0.23, CI = 0.08-0.65, p = .005; Bangladeshi OR = 0.25, CI = 0.07-0.86, p = .027). Frequent contact with relatives reduced mental health service use (OR = 0.45, CI = 0.23-0.89, p = .023). An increase in perceived inadequate support in women's close networks was associated with increased odds of using mental health services (OR = 1.91, CI = 1.11-3.27, p = .019). The influence of social networks on mental health service use did not differ between ethnic groups. CONCLUSIONS: The differential treatment of women from Pakistani and Bangladeshi ethnic groups in primary care settings could be a possible reason for the observed differences in mental health service use.

Help-seeking intentions for early dementia diagnosis in a sample of Irish adults.

OBJECTIVES: To identify factors that may increase intentions to seek help for an early dementia diagnosis. Early dementia diagnosis in Ireland is low, reducing the opportunity for intervention, which can delay progression, reduce psychological distress and increase social supports. METHOD: Using the theory of planned behaviour (TPB), and a mixed methods approach, three focus groups were conducted (N = 22) to illicit attitudes and beliefs about help seeking for an early dementia diagnosis. The findings informed the development of the Help Seeking Intentions for Early Dementia Diagnosis (HSIEDD) questionnaire which was piloted and then administered to a sample of community dwelling adults from Dublin and Kildare (N = 95). RESULTS: Content analysis revealed participants held knowledge of the symptoms of dementia but not about available interventions. Facilitators of help seeking were family, friends and peers alongside well informed health professionals. Barriers to seeking help were a lack of knowledge, fear, loss, stigma and inaccessible services. The quantitative findings suggest the TPB constructs account for almost 28% of the variance in intentions to seek help for an early diagnosis of dementia, after controlling for sociodemographic variables and knowledge of dementia. In the final step of the regression analysis, the main predictors of help seeking were knowledge of dementia and subjective norm, accounting for 6% and 8% of the variance, respectively. CONCLUSION: Future interventions should aim to increase awareness of the support available to those experiencing early memory problems, and should highlight the supportive role that family, friends, peers and health professionals could provide.

Predictors of depression severity in a treatment-seeking sample / Predictores de la gravedad de la depresión en personas adultas que buscan tratamiento

Background/Objective: Depression is a common mental health disorder and an emerging public health concern. Few studies have investigated prevalence and predictors of depression severity in the Irish context. To investigate the relative contribution of known risk factors that predicts depression severity in a treatment-seeking sample of adults in Ireland. Method: As part of a randomised controlled trial of an internet-delivered intervention for depression participants (N=641) completed online screening questionnaires including BDI-II and information associated with common predictors of depression. Results: The mean score on the BDI-II was 24.13 (SD=11.20). Several factors were shown to predict greater severity of depression in the sample including female gender, younger age, unemployment, being single or partnered as opposed to married, previous diagnosis of depression, recent experience of life stressors. Alcohol use, recent losses, knowing a suicide completer, education level, type of employment and income level were not found to be significant. Conclusions: The study contributes to the profiling of the incidence and predictors of severity of depression in an Irish context. The results confirm some of the known risk factors and highlight the need for further research to be carried out on screening for depression and increasing access to interventions (AU)

Antecedentes/Objetivo: La depresión es uno de los trastornos de salud mental más comunes y un incipiente problema de salud pública. Pocos estudios han investigado la prevalencia y factores predictivos de su gravedad en el contexto irlandés. El objetivo del estudio fue investigar los factores de riesgo que predicen la gravedad de la depresión en una muestra de adultos en Irlanda en búsqueda de tratamiento. Método: Los participantes auto-referidos accedieron a una intervención en línea para la depresión. Los participantes (N=641) completaron cuestionarios, incluyendo el BDI-II e información asociada con predictores comunes de la depresión. Resultados: Se encontraron varios factores que predijeron la gravedad de la depresión: ser mujer, ser joven, estar desempleado, estar soltero o con pareja pero no casado, tener diagnóstico previo de depresión y experiencia reciente con factores vitales estresantes. Conclusiones: El estudio contribuye a la elaboración de perfiles de incidencia y factores predictivos en la gravedad de la depresión. Los resultados confirman algunos de los factores de riesgo conocidos y ponen de relieve la necesidad de nuevas investigaciones que lleven a cabo la detección de la depresión así como un mayor acceso a las intervenciones (AU)

Tailoring a brief intervention for illicit drug use and alcohol use in Irish methadone maintained opiate dependent patients: a qualitative process.

BACKGROUND: The World Health Organization (WHO) recommend the tailoring of a brief intervention (BI) programme of research to ensure that it is both culturally and contextually appropriate for the country and the environment in which it is being tested. The majority of BI research has been conducted with non-opioid dependent participants. The current study developed a tailored BI for illicit drug use and alcohol use to a methadone maintained opioid dependent polydrug using cohort of patients. METHODS: Focus groups with staff and one-to-one qualitative interviews with patients guided the tailoring of all intervention materials for use in a subsequent cluster randomised controlled trial (RCT). This was done to make them contextually appropriate to an opioid dependent cohort and culturally appropriate to Ireland. Thematic analyses were utilised. RESULTS: The BI was modified to ensure its compatibility with the culture of an Irish drug using population, with elements of motivational interviewing (MI) and personalised feedback incorporated. Example scripts of a screening and BI were included, as was an algorithm to facilitate clinicians during a session. Modifications to the 'Substance Use Risk' cards included weighting the severity of the problems, writing the language in the first person to personalise the feedback and including tick boxes so as to further highlight the relevant risk factors for individual patients. Photographs of key risk factors were included to display pictorially risks for illiterate or semi-literate patients. Examples of the interaction of particular substances with methadone were of particular importance to this group. Modifications of the 'Pros and Cons of Substance Use/Reasons to Quit or Cut Down' included additional categories such as addiction, crime and money that were salient to this cohort. The manual was used to standardise training across trial sites. CONCLUSION: The research team was faithful to WHO recommendations to tailor BI programmes that are culturally and contextually appropriate to the treatment cohort and clinical environment. Outcome data from the cluster RCT have demonstrated that the tailored intervention was effective.

The use of pain relief during labor among migrant obstetric populations.

OBJECTIVE: To identify patterns in intrapartum analgesia use in the migrant obstetric population. METHODS: A retrospective analysis included all deliveries with neonates above 500g in weight at a university hospital in Dublin, Ireland between 2009 and 2013. Analgesia was classified as neuraxial or non-neuraxial. Parturients were excluded owing to missing data, elective cesarean deliveries, and the use of analgesia during treatment for obstetric complications. RESULTS: There were 36 689 deliveries included in the present study. Increased odds of not using neuraxial analgesia during delivery were observed among migrant parturients from North Africa, Sub-Saharan Africa, the Far East, India, and Eastern Europe compared with western Europe (all P<0.05). Increased odds of not receiving any analgesia during delivery were demonstrated among parturients from North Africa, Sub-Saharan Africa, the Far East, North America, Eastern Europe, and India compared with western Europe (all P<0.05). CONCLUSIONS: Disparities exist in the use of intrapartum analgesia between migrant and western European populations in Ireland. Migrants from Africa were the least likely to use any analgesia. The reasons for this are speculative but could be influenced by expectations of care in the region of origin.
