Distribution of tuberculosis in migrant children and young people in Europe: a retrospective database analysis of European data.

OBJECTIVE: The burden of tuberculosis (TB) in migrant children and young people (CYP) is commonly overlooked, despite the increasing incidence of TB in migrant populations in the European region. This study aimed to examine the distribution and disease characteristics of TB among migrant and native-born CYP through analysis of data from the European Centre for Disease Prevention and Control (ECDC) surveillance system (TESSy). STUDY DESIGN: Retrospective database analysis. METHODS: A retrospective database analysis was conducted on all CYP TB cases (0-17 years) reported to TESSy (1995-2017), exploring distribution, site of TB, and presence of MDR-TB using multivariate analysis in R statistical software. RESULTS: Of the 73,176 CYP TB cases reported in the EU/EFTA (1995-2017), 24.4% (n = 17,879) occurred in migrant CYP and 75.6% (n = 55,297) occurred in native-born CYP. Migrant CYP were more likely (P < 0.001) to have pulmonary TB (OR: 1.90; 95% CI: 1.74-2.09) and unsuccessful treatment outcomes (OR: 2.05; 95% CI: 1.74-2.40) compared to native-born CYP. The proportion of extrapulmonary TB, compared to pulmonary TB across total CYP cases was higher than the existing evidence base. CONCLUSIONS: Overall, there were significant differences in the site of TB and treatment outcomes between migrant and native-born CYP. To improve outcomes, TB screening and detection practices should focus on facilitating care in migrant CYP. However, to better understand the implications of these findings on broader TB control, TB among CYP should be addressed more frequently in reports and research.

The prevalence of non-communicable diseases among Syrian refugees in Syria's neighbouring host countries: a systematic review and meta-analysis.

OBJECTIVES: Alarming rates of non-communicable diseases (NCDs) have been observed in low- and middle-income countries (LMICs) where most refugees reside. There is concern Syrian refugees may experience significant NCD-related health needs, which have significant health implications, including in the context of the COVID-19 pandemic, and which must be addressed by health systems in neighbouring host countries. Although primary studies on this topic exist, there has been no comprehensive synthesis of the existing evidence base. The aim of this systematic review and meta-analysis was to synthesise evidence on the prevalence of NCDs among Syrian refugees residing in neighbouring host countries. STUDY DESIGN: This was a systematic review and meta-analysis. METHODS: The review was carried out in line with PRISMA guidelines (PROSPERO CRD420201970430). MEDLINE, CINAHL, EMBASE and PubMed databases were searched from 1 January 2011 to 1 November 2021. Peer-reviewed studies reporting prevalence data on the five most common NCDs among adult Syrian refugees living in Turkey, Lebanon or Jordan were included. Methodological quality was assessed using the Joanna Briggs Institute critical appraisal checklist for prevalence studies. Meta-analysis was carried out to estimate the pooled prevalence of these NCDs in community and primary care settings. RESULTS: A total of 466 citations were identified, 18 of which were included, representing 237,723 Syrian refugees. In community settings, the prevalence of hypertension, diabetes mellitus type II, cardiovascular diseases, chronic respiratory diseases and arthritis was 24% (95% confidence interval: 17-32), 12% (8-15), 5% (3-7), 4% (3-5) and 11% (7-14), respectively. The prevalence of hypertension 35% (33-36) and diabetes mellitus type II 48% (24-72) were significantly higher in primary care settings. CONCLUSION: The findings demonstrate a high prevalence of NCDs among Syrian refugees. Evidence-based preventive and management interventions for NCDs are needed in this context to address acute health needs during the COVID-19 pandemic and the longer-term health burden of NCDs.

Identifying research questions for HIV, tuberculosis, tuberculosis-HIV, malaria, and neglected tropical diseases through the World Health Organization guideline development process: a retrospective analysis, 2008-2018.

OBJECTIVES: World Health Organization (WHO) guidelines for health programmes and healthcare delivery are the foundation of its technical leadership in public health and essential to decision-making globally. A key function of guideline development is to identify areas in which further evidence is needed because filling these gaps will lead to future improvements in population health. The objective of this study was to examine the knowledge gaps and research questions for addressing those gaps generated through the WHO guideline development process, with the goal of informing future strategies for improving and strengthening the guideline development process. STUDY DESIGN: We did a systematic, retrospective analysis of research questions identified in the published guidelines. METHODS: We analyzed guidelines published between January 1, 2008, and December 31, 2018, by the Communicable Diseases Cluster in five disease areas: tuberculosis (TB), HIV, malaria, TB-HIV, and neglected tropical diseases (NTDs). Research questions were extracted independently by two researchers. We analyzed the distribution of research questions by disease and by topic category and did a qualitative assessment of optimum practice for research question generation during the guideline development process. RESULTS: A total of 48 guidelines were included: 26 on HIV, 1 on malaria, 11 on TB, 5 on TB/HIV, and 5 on NTDs. Overall, 36 (75%) guidelines encompassed a total of 360 explicit research questions; the remainder did not contain specific research questions. The number of research questions that focused on TB was 49, TB/HIV was 38, HIV was 250, and NTDs was 23. The number of research questions that focused on diagnosis was 43 (11.9%) of 360, prevention was 62 (17.2%), treatment was 103 (28.6%), good practice was 12 (3.3%), service delivery was 86 (23.8%), and other areas was 54 (15%). Research questions were often not formulated in a specific or actionable way and were hard to identify in the guideline. Examples of good practice identified by the review team involved the generation of specific and narrowly defined research questions, with accompanying recommendations for appropriate study design. CONCLUSIONS: The WHO must strengthen its approach to identifying and presenting research questions during the guideline development process. Ensuring access to research questions is a key next step in adding value to the guideline development process.

Vaccination status and needs of asylum-seeking children in Denmark: a retrospective data analysis.

OBJECTIVES: Asylum seekers to Europe may come from war-torn countries where health systems have broken down, and there is evidence that asylum-seeking children have low coverage of childhood vaccinations, as well as uptake of immunisations in host countries. Such gaps in immunisation have important implications for effective national vaccination programmes. How we approach vaccination in children and adults entering Western Europe, where as a group they face barriers to health services and screening, is a growing debate; however, there are limited data on the vaccination status of these hard-to-reach communities, and robust evidence is needed to inform immunisation strategies. The aim of this study was to explore the vaccination status and needs of asylum-seeking children and adolescents in Denmark. STUDY DESIGN: We conducted a retrospective data analysis of anonymised patient records for asylum-seeking children and adolescents extracted from the Danish Red Cross database. METHODS: We retrospectively searched the Danish Red Cross database for children and adolescents (aged 3 months-17 years) with active asylum applications in Denmark as of October 28, 2015. Data were extracted for demographic characteristics, vaccination status and vaccinations needed by asylum-seeking children presenting to Red Cross asylum centres for routine statutory health screening. RESULTS: We explored the vaccination status and needs of 2126 asylum-seeking children and adolescents. About 64% of the study population were male and 36% were female. Eight nationalities were represented, where 33% of the total of children and adolescents were not immunised in accordance with Danish national guidelines, while 7% were considered partly vaccinated, and 60% were considered adequately vaccinated. Afghan (57% not vaccinated/unknown) and Eritrean (54% not vaccinated/unknown) children were the least likely to be vaccinated of all nationalities represented, as were boys (37% not vaccinated/unknown) compared with girls (27% not vaccinated/unknown) and children and adolescents aged between 12 and 17 years (48% not vaccinated/unknown) compared with 6- to 11-year olds (26%) and 0- to 5-year olds (22%). The health screenings resulted in 1328 vaccinations. The most commonly needed vaccines were diphtheria, tetanus, pertussis, polio and Haemophilus influenzae type b, (DTaP/IPV/Hib) which comprised 49% of the vaccines distributed, followed by the pneumococcal vaccine (Prevnar) (28%) and measles, mumps and rubella (MMR) vaccine (23%). CONCLUSIONS: The finding that nearly one-third of asylum-seeking children and adolescents in Denmark were in need of further vaccinations highlights the gaps in immunisation coverage in these populations. These results point to the need to improve access to health services and promote national vaccine programmes targeted at these communities to facilitate vaccination uptake and increase immunisation coverage to reduce the risk of preventable infectious diseases among asylum-seeking children.

Stress, health and quality of life of female migrant domestic workers in Singapore: a cross-sectional study.

BACKGROUND: There is a global increase in migrant workers. In Singapore, there are over 230,000 migrant domestic workers (MDWs). Female MDWs may experience high levels of stress and social isolation, which may negatively impact on their health and quality of life. There have also been documented cases of abuse and exploitation. However, there is a lack of empirical research with this population. This study aimed to investigate factors impacting on the health and quality of life of female MDWs in Singapore, including socio-demographic and job related characteristics, stress, social isolation, and working management style. METHODS: A cross-sectional survey was carried out with 182 female MDWs in Singapore. The survey examined health and quality of life (WHOQoL-Bréf), social connectedness (the Friendship Scale), and preferred and experienced working management style (the Theory X and Theory Y Questionnaire). Descriptive analyses were carried out in addition to ANOVA, t-tests, and chi-square tests, followed by a multivariate analysis using linear regression. RESULTS: Participants were found to have good overall quality of life and satisfaction with health. Age and working experience were found to be significantly (p < 0.05) associated with overall quality of life and three domains (psychological, social, and environmental health). Agreement between experienced and preferred working management style was also found to be associated with higher quality of life scores (with the exception of the social relationships domain). Though women reported relatively good overall quality of life, more than half of participants reported feeling stressed. In addition, nearly 20% of participants reported being isolated or very isolated. Stress was identified to be associated with isolation. In the multivariate analysis, stress was found to contribute to worse quality of life in all domains except social relationships, after adjusting for confounders. Social connectedness was positively associated with all domains of quality of life, and agreement of working management style was positively associated with physical health, psychological health and environmental quality of life. CONCLUSIONS: The findings serve as an evidence-base pointing to the need for policies aimed at decreasing stress and social isolation among female MDWs in order to improve their health and quality of life.

Multidrug-resistant tuberculosis and migration to Europe.

Multidrug-resistant tuberculosis (MDR-TB) in low-incidence countries in Europe is more prevalent among migrants than the native population. The impact of the recent increase in migration to EU and EEA countries with a low incidence of TB (<20 cases per 100 000) on MDR-TB epidemiology is unclear. This narrative review synthesizes evidence on MDR-TB and migration identified through an expert panel and database search. A significant proportion of MDR-TB cases in migrants result from reactivation of latent infection. Refugees and asylum seekers may have a heightened risk of MDR-TB infection and worse outcomes. Although concerns have been raised around 'health tourists' migrating for MDR-TB treatment, numbers are probably small and data are lacking. Migrants experience significant barriers to testing and treatment for MDR-TB, exacerbated by increasingly restrictive health systems. Screening for latent MDR-TB is highly problematic because current tests cannot distinguish drug-resistant latent infection, and evidence-based guidance for treatment of latent infection in contacts of MDR patients is lacking. Although there is evidence that transmission of TB from migrants to the general population is low-it predominantly occurs within migrant communities-there is a human rights obligation to improve the diagnosis, treatment and prevention of MDR-TB in migrants. Further research is needed into MDR-TB and migration, the impact of screening on detection or prevention, and the potential consequences of failing to treat and prevent MDR-TB among migrants in Europe. An evidence-base is urgently needed to inform guidelines for effective approaches for MDR-TB management in migrant populations in Europe.
