Public health response to large influx of asylum seekers: implementation and timing of infectious disease screening.

BACKGROUND: Infectious disease screening of migrants at increased risk is a feature of national infection prevention and control measures. Asylum seekers in Finland are offered screening of tuberculosis (TB), hepatitis B, human immunodeficiency virus infection (HIV) and syphilis based on individual risk assessment. We aimed to evaluate the public health response to a large influx of asylum seekers to Finland in 2015-2016 with respect to national guidelines on initial health services and infectious disease screening. METHODS: We used immigration and healthcare procurement data for all 38,134 asylum seekers to Finland during 2015-2016 to assess the implementation, timing and yields of infectious disease screening. RESULTS: The coverage of pulmonary TB screening was 71.6% [95% CI 71.1-72.0%] and that of hepatitis B, HIV or syphilis 60.6% [60.1-61.1%] among those eligible for screening. The estimated average delay from arrival to pulmonary TB screening was 74 days for adults and 43 days for children. Delay to hepatitis B, HIV and syphilis screening was 91 days for adults and 47 days for children. The seroprevalence of hepatitis B surface antigen positivity was 1.4% [95% CI 1.3-1.6%], HIV 0.3% [95% CI 0.1-0.4%] and Treponema pallidum specific antibodies 1.0% [95% CI 0.8-1.1%]. Data did not allow assessment of yields of pulmonary TB screening. CONCLUSIONS: Up to one third  of asylum seekers were not reached by screening and screenings were delayed from target timeframes. Children, as a vulnerable population, were screened earlier than adults. To ensure higher screening coverage, infectious disease risks should be reassessed and screening completed at contacts to healthcare during the post-asylum phase of integration. The large influx of asylum seekers to Finland in 2015-2016 tested the country's public health preparedness. After action reviews of the public health response to the large migrant influx such as screening implementation can be used for evidence-based improvement of public health preparedness and guidelines for initial health services and infectious disease screening.

Health promotion among the population of foreign origin in Finland involves special issues.

The population of foreign origin in Finland is a heterogenic group, diverse for example with respect to reasons for and age at migration. While migration to Finland is a recent phenomenon, the size of the population of foreign origin has grown rapidly and will continue to increase. Changes in the population structure need to be taken into account in health promotion. For example lifestyle, health status, functional capacity, mental health, infectious diseases and reproductive health differ in foreign origin population compared with the general Finnish population. These differences may provide opportunities but also create challenges for service provision and health promotion planning.

A plasma metabolite score of three eicosanoids predicts incident type 2 diabetes: a prospective study in three independent cohorts.

INTRODUCTION: Peptide markers of inflammation have been associated with the development of type 2 diabetes. The role of upstream, lipid-derived mediators of inflammation such as eicosanoids, remains less clear. The aim of this study was to examine whether eicosanoids are associated with incident type 2 diabetes. RESEARCH DESIGN & METHODS: In the FINRISK (Finnish Cardiovascular Risk Study) 2002 study, a population-based sample of Finnish men and women aged 25-74 years, we used directed, non-targeted liquid chromatography-mass spectrometry to identify 545 eicosanoids and related oxylipins in the participants' plasma samples (n=8292). We used multivariable-adjusted Cox regression to examine associations between eicosanoids and incident type 2 diabetes. The significant independent findings were replicated in the Framingham Heart Study (FHS, n=2886) and DIetary, Lifestyle and Genetic determinants of Obesity and Metabolic syndrome (DILGOM) 2007 (n=3905). Together, these three cohorts had 1070 cases of incident type 2 diabetes. RESULTS: In the FINRISK 2002 cohort, 76 eicosanoids were associated individually with incident type 2 diabetes. We identified three eicosanoids independently associated with incident type 2 diabetes using stepwise Cox regression with forward selection and a Bonferroni-corrected inclusion threshold. A three-eicosanoid risk score produced an HR of 1.56 (95% CI 1.41 to 1.72) per 1 SD increment for risk of incident diabetes. The HR for comparing the top quartile with the lowest was 2.80 (95% CI 2.53 to 3.07). In the replication analyses, the three-eicosanoid risk score was significant in FHS (HR 1.24 (95% CI 1.10 to 1.39, p<0.001)) and directionally consistent in DILGOM (HR 1.12 (95% CI 0.99 to 1.27, p=0.07)). Meta-analysis of the three cohorts yielded a pooled HR of 1.31 (95% CI 1.05 to 1.56). CONCLUSIONS: Plasma eicosanoid profiles predict incident type 2 diabetes and the clearest signals replicate in three independent cohorts. Our findings give new information on the biology underlying type 2 diabetes and suggest opportunities for early identification of people at risk.

Refugee crisis in Finland: Challenges to safeguarding the right to health for asylum seekers.

In 2015 Finland received an unprecedented number of asylum seekers, ten times more than in any previous year. This surge took place at a time the Finnish Government was busily undergoing a wide-range health and social care reform amid growing nationalist and populist sentiments. Our aim is to explore the governance of a parallel health system for asylum seekers with a right-to-health approach. We concentrated on three right to health features most related to the governance of asylum seeker health care, namely Formal recognition of the right to health, Standards and Coordination mechanisms. Through our qualitative review, we identified three major hurdles in the governance of the system for asylum seekers: 1) Ineffectual and reactive national level coordination and stewardship; 2) Inadequate legislative and supervisory frameworks leading to ineffective governance; 3) Discrepancies between constitutional rights to health, legal entitlements to services and guidance available. This first-time large-scale implementation of the policies exposed weaknesses in the legal framework and the parallel health system. We recommend the removal of the parallel system and the integration of asylum seekers' health services to the national public health care system.

Endotoxemia, immune response to periodontal pathogens, and systemic inflammation associate with incident cardiovascular disease events.

OBJECTIVE: In periodontitis, overgrowth of gram-negative bacteria may cause endotoxemia and systemic inflammation leading to cardiovascular diseases (CVD). We investigated in a prospective study the associations of serum endotoxin, antibodies to periodontal pathogens, and inflammation markers with the risk of incident CVD. METHODS AND RESULTS: The FINRISK 1992 cohort of 6051 individuals was followed up for 10 years. We examined 185 incident CVD events and a control cohort of 320 individuals using a prospective case-cohort design. High antibody response to periodontal pathogens independently predicted incident CVD events with hazard ratios (HR, quartile 4 versus quartiles 1 to 3, 95% CI) of 1.87 (1.13 to 3.08). The subjects with a high antibody response and high CRP or interleukin (IL)-6 had multivariate-adjusted HRs of 3.01 (1.27 to 7.09) and 3.11 (1.42 to 6.83) compared with low-responders, respectively. The corresponding HRs for high endotoxin concentration were 1.82 (1.22 to 2.73, alone), 3.92 (1.99 to 7.74, with CRP), 3.54 (1.78 to 7.03, with IL-6), and 2.26 (1.13 to 4.52, with tumor necrosis factor (TNF)-alpha) after adjusting for age and gender. These associations were abolished after adjusting for serum lipids. High endotoxin/HDL ratio, however, had a multivariate-adjusted HR of 1.92 (1.19 to 3.08) for CVD events. CONCLUSIONS: Our results suggest that the exposure to periodontal pathogens or endotoxin induces systemic inflammation leading to increased risk for CVD.

C-reactive protein, interleukin-6 and tumor necrosis factor alpha as predictors of incident coronary and cardiovascular events and total mortality. A population-based, prospective study.

Previous studies have shown an association between serum C-reactive protein (CRP) and cardiovascular disease (CVD) risk. The roles of interleukin-6 (IL-6) and tumor necrosis factor alpha (TNFalpha) are less well established. The aim of the present study was to analyze the associations of CRP, IL-6 and TNFalpha with incident coronary heart disease (CHD) events, CVD events, and total mortality. A random population sample, including men and women aged 25-64 years was examined in Finland in 1992. The sample size was 7,927 and 6,051 (76%) participated. The cohort was followed up until the end of 2001. During the follow-up, 151 incident CHD events, 205 CVD events and 183 deaths from any cause were observed. A stratified random subsample (n=313) was used as the comparison group. After adjustment for conventional CVD risk factors, CRP showed a significant association with CHD risk in men (HR=2.39, 1.08-5.28, comparing fourth quartile to the first quartile). This association remained significant after further adjustment for TNFalpha. TNFalpha also was a significant predictor of CHD among men, but the association was nonlinear (HR=2.21, 1.18-4.14 comparing the three upper quartiles to the first quartile). Further adjustment for CRP did not change this association substantially. Both CRP and TNFalpha predicted also all CVD events and total mortality among men. Among women the findings were nonsignificant. In conclusion, CRP and TNFalpha were significant, independent predictors of CHD and CVD events and total mortality among men. These findings provide further support to the important role of inflammation in the pathogenesis of CVD.
