Allergic diseases are common and frequently coexist. Allergen immunotherapy (AIT) is a disease-modifying treatment for IgE-mediated allergic disease with effects beyond cessation of AIT that may include important preventive effects. The European Academy of Allergy and Clinical Immunology (EAACI) has developed a clinical practice guideline to provide evidence-based recommendations for AIT for the prevention of (i) development of allergic comorbidities in those with established allergic diseases, (ii) development of first allergic condition, and (iii) allergic sensitization. This guideline has been developed using the Appraisal of Guidelines for Research & Evaluation (AGREE II) framework, which involved a multidisciplinary expert working group, a systematic review of the underpinning evidence, and external peer-review of draft recommendations. Our key recommendation is that a 3-year course of subcutaneous or sublingual AIT can be recommended for children and adolescents with moderate-to-severe allergic rhinitis (AR) triggered by grass/birch pollen allergy to prevent asthma for up to 2 years post-AIT in addition to its sustained effect on AR symptoms and medication. Some trial data even suggest a preventive effect on asthma symptoms and medication more than 2 years post-AIT. We need more evidence concerning AIT for prevention in individuals with AR triggered by house dust mites or other allergens and for the prevention of allergic sensitization, the first allergic disease, or for the prevention of allergic comorbidities in those with other allergic conditions. Evidence for the preventive potential of AIT as disease-modifying treatment exists but there is an urgent need for more high-quality clinical trials.

BackgroundAs in many European countries, undocumented migrants in Denmark have restricted access to healthcare. The aim of this study is to describe and analyse undocumented migrants' experiences of access to healthcare, use of alternative health-seeking strategies; and ER nurses' experiences in encounters with undocumented migrants.MethodsQualitative design using semi-structured interviews and observations. The participants included ten undocumented South Asian migrants and eight ER nurses.ResultsUndocumented migrants reported difficulties accessing healthcare. The barriers to healthcare were: limited medical rights, arbitrariness in healthcare professionals' attitudes, fear of being reported to the police, poor language skills, lack of network with Danish citizens, lack of knowledge about the healthcare system and lack of knowledge about informal networks of healthcare professionals. These barriers induced alternative health-seeking strategies, such as self-medication, contacting doctors in home countries and borrowing health insurance cards from Danish citizens. ER nurses expressed willingness to treat all patients regardless of their migratory status, but also reported challenges in the encounters with undocumented migrants. The challenges for ER nurses were: language barriers, issues of false identification, insecurities about the correct standard procedures and not always being able to provide appropriate care.ConclusionsUndocumented migrants face formal and informal barriers to the Danish healthcare system, which lead to alternative health-seeking strategies that may have adverse effects on their health. This study shows the need for policies and guidelines, which in accordance with international human rights law, ensure access to healthcare for undocumented migrants and give clarity to healthcare professionals.

Population aging and the associated changes in demographic structures and healthcare needs is a key challenge across Europe. Healthy aging strategies focus on ensuring the ability to maintain health, quality of life and independent living at old age. Concurrent to the process of population aging, the demographics of Europe are affected by increased migration resulting in substantial ethnic diversity. In this paper, we narratively review the health profile of the growing proportion of aging migrants in Europe, outline key factors shaping health among this diverse group and consider ways of addressing their healthcare needs.Although factors shaping aging processes are largely similar across populations, migrant-specific risk factors exist. These include exposure to health risks before and during migration; a more disadvantaged socioeconomic position; language barriers and low health literacy; cultural factors influencing health-seeking behaviours; and psychosocial vulnerability and discrimination affecting health and quality of life. Overall, migrants experience the same morbidity and mortality causes as the native populations, but with different relative importance, severity and age of onset and with substantial differences within and between migrant groups. Little is known regarding health behaviours among aging migrants, although differences in cancer screening behaviours have been identified. Indications of widening health differentials between migrants and native populations with age and informal barriers to quality healthcare for aging migrants are causes of concern.In conclusion, there is a need for attention to migration alongside other determinants of healthy aging. The diversity in individual characteristics, life course processes and contextual factors shaping aging processes among migrants point to the need for a sensitive and comprehensive approach to policies, practices and research within the field of healthy aging. This is important to accommodate for the needs of the growing number of aging migrants in Europe and counter inequities in health and well-being at old age.

Background. Inequality in use of mammography screening across population groups is a concern since migrants are more likely to become non-users compared to the general population. The aim of this study was to a) identify determinants of participation among migrant groups and Danish-born women with emphasis on the effect of household size, socioeconomic position and use of healthcare services, and b) test whether effects of determinants were consistent across migrant and non-migrant groups. Material and methods. We used data from the fi rst eight invitation rounds of the mammography screening programme in Copenhagen, Denmark (1991-2008) in combination with register-based data. Results. The crude odds ratio (OR) for not participating in mammography screening was 1.38 (95% CI, 1.30-1.46) for women born in other-Western and 1.80 (95% CI, 1.71-1.90) for women born in non-Western countries compared to Danish-born women. The adjusted OR was 1.14 (95% CI, 1.06-1.21) for other-Western and 1.19 (95% CI, 1.11-1.27) for women born in non-Western countries. Lack of contact with a general practitioner or dental services, and not being employed had a signifi cant negative effect on use of mammography screening. Higher-educated women were signifi cantly less likely to use mammography screening in all groups whilst hospitalisation had a signifi cant effect among Danish-born women. Living alone was consistently associated with non-use of mammography screening. The probability of becoming a non-user was signifi cantly less among women living within households of two to four persons compared to women living alone. Except in the case of age and hospitalisation, trends were similar across country of birth, but the relative importance of specifi c determinants in explaining use of mammography screening differed. Conclusion. Household size, socioeconomic position and use of healthcare services were determinants of participation in mammography screening. This study emphasises the need for conducting refi ned analyses distinguishing among subgroups within diverse populations when explaining differences in screening behaviour.
