The aim of this study was to determine the health and social problems and related behaviors of the Roma population by using the Omaha System. The data were collected from 650 Roma individuals. This study was a cross-sectional secondary data analysis and the data were collected in two stages. First, the "Technical Assistance for Promoting Social Inclusion in Densely Roman Populated Areas Project (SIROMA)" Act team evaluated health problems among Roma individuals. Second, data were reanalyzed using the Omaha System. When sociodemographic and economic characteristics were evaluated, low education level, adolescent marriages, a high number of live births, soiled living areas, unemployment, and substance use were found in the Roma population. In this context, using the Omaha System, the frequently diagnosed health and social problems were Sanitation (13.5%), Healthcare supervision (11.8%), Nutrition (11.0%), Income (9.8%), Respiration (8.3%), Substance use (7.3%), and Neighborhood/workplace safety (6.0%). This study results found out that the Roma population is less prone than natives to have healthy lifestyle behaviors and more prone to experience a deterioration in both their general and mental health. The Omaha System is a valid method used to collect and analyze data for a vulnerable population in the community. Also, it has been proven that the Omaha System Problem Classification Scheme can provide a more detailed and comprehensive assessment.

Objective The aims of the study were: (1) to clarify the definitions of “migrant” used in occupational health research; (2) to summarize migrant workers’ industry sectors, occupations and employment conditions; (3) to identify the occupational health and safety services available to migrant workers; (4) to summarize work-related health problems found among migrant workers; (5) to identify the methodological challenges to research into occupational health of migrant workers; and (6) to recommend improvements in migrant occupational health research. Methods This position paper was prepared by researchers from several European countries and Australia, working within the EU COST Action OMEGA-NET. The paper drew on two recent systematic reviews on the occupational health of international migrant workers and other literature, and also identified uncertainties and gaps in the research literature. Migrants may, for example, be temporary or permanent, moving for specific jobs migrants or other reasons. Their ethnicity and language capabilities will affect their work opportunities. Results The occupational health literature seldom adequately identifies the heterogeneity or characteristics of the migrant group being studied. Migrants tend to work in more physically and mentally demanding environments with higher exposures than native workers. Migrants tend to have an increased risk of physical and mental ill health, but less access to health care services. This has been demonstrated recently by high rates of COVID-19 and less access to health care. There have been a number of cross-sectional studies of migrant health but few long-term cohort studies were identified. Other study designs, such as registry-based studies, surveys and qualitative studies may complement cross-sectional studies. Mixed-methodology studies would be valuable in research on migrants’ occupational health. Language and lack of trust are barriers to migrant research participation. Conclusion Targeted research, especially longitudinal, identifying how these economically important but often-vulnerable workers can be best assisted is needed. Researchers should identify the characteristics of the migrant workers that they are studying including visa/migration circumstances (temporary, permanent, undocumented), racial and ethnic characteristics, existing skills and language abilities.

Occupational skin diseases are the one of the most frequent diseases in many industrialized countries. The studies about skin disease (SD) on young workers were limited.In this study, we aim to evaluate the prevalence of SD symptoms and related risk factors among young workers in high-risk occupations.This cross-sectional study was undertaken between 2011 and 2012 in two vocational training centres. We included 455 young workers who were working as hairdressers, jewellers, or car mechanics. Data were collected with the Nordic Occupational Skin Questionnaire, which was adapted to Turkish for young workers.The average age of the young workers was 17.9 ± 1.7 years. Of the 455 young workers, 52.7% were female and 47.3% were male. During the previous 12 months, the prevalences of the total SD symptoms, hand/forearm eczema symptoms and urticaria symptoms were 49.7%, 44.4%, and 13.4%, respectively. Those who worked as car mechanics were 5.8 times more likely [odds ratio (OR) 5.81, 95%CI: 2.58-13.10) to have a dry skin type, 2.9 times more likely (OR 2.86, 95%CI: 1.72-4.75) to work for12 h daily, 2.6 times more likely (OR 2.59, 95%CI: 1.25-5.35) to have worked for5 years, and 3.0 times more likely (OR 3.05, 95%CI: 1.14-8.14) to have SD symptoms.The results indicate that young workers in high-risk jobs have a high frequency of skin symptoms. These results could provide a basis for occupational health professionals to plan prevention programmes for young workers.

Natural killer (NK) cells are large granular lymphocytes of the innate immune system that exert a potent function against infected and tumor cells. Although NK cells were originally defined by their capacity to lyse target cells and produce interferon-gamma without prior activation, recent studies showed that NK cells also display a potent regulatory function. They are activated or inhibited through the ligation of germline-encoded receptors and are involved in mediating cytotoxicity, producing cytokines and providing costimulation to cells of the adaptive immune system. NK cells play important roles in viral infections, autoimmunity, pregnancy, cancer and bone marrow transplantation, but little is known about the role of NK cells in allergy. Recent developments in the understanding of the role of human NK cells in allergy are overviewed.
