ReviewMigration and health: exploring the role of migrant status through register-based studies.
This thesis aims to explore migrant status as a determinant in register-based studies on migrant health. It is based on eight studies that investigate the following three main issues: 1) What is the importance of migrant status for morbidity patterns among migrants compared with Native Danes? 2) Do migrant status and ethnicity affect clinical indicators of access among migrants compared with native Danes? 3) What is the importance of migrant status for mortality patterns among migrants compared with Native Danes? The thesis builds on a register-based historical prospective cohort design. Through Statistics Denmark, all refugees (n = 29,174) and family reunification immigrants (n = 33,287) who received residence permits in Denmark from 1 January 1993 to 31 December 1999 were included and matched 4:1 on age and sex with Native Danes. ⋯ It also demonstrates the role of migrant status as a useful variable in migrant studies in addition to ethnicity. Across all three sub-themes, inequalities in morbidity patterns were sometimes in favour of migrants and sometimes in favour of native Danes. Finally, inequalities in health were more pronounced for the refugee group, which was consistently more at risk compared with native Danes or which apparently benefited less from the protective factors of being a migrant compared with family reunification immigrants.

ReviewA cohort study of Danish patients with interstitial lung diseases: burden, severity, treatment and survival.
Interstitial lung diseases (ILDs) form a heterogeneous group of rare diseases characterised by varying degrees of pulmonary inflammation and fibrosis. We hypothesised that IPF and unclassifiable ILD were common in a Danish ILD cohort and that prognostic factors based on disease characteristics and comorbidities could be identified The aims of the PhD study were to describe the demographics of ILD in Central Denmark, to characterise the distribution of ILD diagnoses, and to assess prognostic factors in IPF and unclassifiable ILD. The study is based on a cohort of 431 ILD patients referred to our department during a 6-year period. ⋯ Unclassifiable ILD is frequent in daily clinical practice but has not been characterised in detail. Our study showed that it was possible to identify predictors of outcome and to validate the ILD-GAP model in this cohort. The study also showed that the Disease Behaviour Classification can be used in the management of patients with unclassifiable ILD.

Blood pressure and arterial stiffness in obese children and adolescents.
Obesity, elevated blood pressure (BP) and arterial stiffness are risk factors for cardiovascular disease. A strong relationship exists between obesity and elevated BP in both children and adults. Obesity and elevated BP in childhood track into adult life increasing the risk of cardiovascular disease in adulthood. ⋯ In perspective, it is reassuring that weight changes are accompanied with a change in 24-hour BP as ambulatory BP is the most precise measure to evaluate the BP burden, and it emphasises the use of 24-hour ambulatory BP measurements in children and adolescents. It is important to recognise, that obese children who recover their normal weight before adulthood will have a similar cardiovascular risk as those who were never obese. Hence, early treatment and prevention of childhood obesity is important because it may prevent irreversible damage to the cardiovascular system.

Randomized Controlled Trial Multicenter StudyLegislation hampers medical research in acute situations.
Informed consent in incapacitated adults is permitted in the form of proxy consent by both the patients' closest relative (next of kin, NOK) and general practitioner (GP). In research in acute situations not involving pharmaceuticals, Danish legislation allows for randomisation and subsequent proxy consent, as soon as possible. The aim of this study was to describe the delay associated with obtaining consent and to assess whether consent from NOK or GP/Danish Health and Medicines Authority is obtained with delays beyond the intervention. ⋯ This work was supported by the European Regional Development Fund through the Interreg IV A OKS programme (NYPS ID: 167157) with regards to authors JHT, CH, NN and JK.

Randomized Controlled TrialThe effect of direct referral for fast CT scan in early lung cancer detection in general practice. A clinical, cluster-randomised trial.
This PhD thesis is based on the project "The effect of direct referral for fast CT scan in early lung cancer detection in general practice. A clinical, cluster-randomised trial", performed in Denmark in 2010-2013. The thesis includes four papers and focuses on early lung cancer diagnostics in general practice. ⋯ This thesis contributes to the knowledge of the early diagnosis of lung cancer in Denmark. General practice was found to play an important role, but only a small part of Danish lung cancer patients were diagnosed from general practice through the fast-track pathway. This together with the fact that a high proportion of patients had two or more radiographs within the 90 days preceding the diagnosis indicate that other diagnostic strategies should be tested in an attempt to provide GPs with the best opportunity for early diagnosis. This thesis provides evidence that GPs are, indeed, able to refer patients straight-to-test in the fast-track pathway. This knowledge may be used when organising other fast tracks. Furthermore, GPs participating in education about early lung cancer diagnosis were willing to refer patients direct to low-dose CT (LDCT) from primary care. Half of the patients needed further diagnostic work-up, and 2.3% of all patients referred were diagnosed with lung cancer. In addition, many lung diseases were diagnosed by LDCT. No effect on time to diagnosis or stage at diagnosis was found when patients from intervention GPs were compared with patients from control GPs. The effect of combining direct access to LDCT with referral to the existing fast-track pathway should be analysed as it may ensure earlier and faster lung cancer detection in primary care. Direct access to LDCT scan may also be an alternative to lung cancer screening. Furthermore, if a LDCT screening program is going to be implemented, it should be considered to supplement the program with access to CT directly from primary care for the symptomatic, not-screened patients.
