Tuberculosis rarely developed among contacts, and preventive chemotherapy effectively reduced the tuberculosis risk among IGRA-positive contacts. Although the negative predictive value of IGRAs is high, the risk for the development of tuberculosis is poorly predicted by these assays.

In Denmark, TB carries substantial mortality. Among those who die, 12% are reported to die from TB. A high relative mortality among younger adults underscores the importance of continually targeting high-risk TB groups in low-incidence countries.

Survival was impaired for patients with ILD for all levels of the DCcs, although increasing burden of co-morbidity tended to close the mortality gap.

Persistent symptoms after hospitalization with COVID-19 are common, but the frequency and severity of these symptoms are insufficiently understood. We aimed to describe symptoms and pulmonary function after hospitalization with COVID-19. Patients hospitalized with COVID-19 in Central Denmark Region were invited for follow-up 3 months after discharge. Clinical characteristics, patient reported outcomes (Fatigue Assessment Scale (FAS), anxiety and depression (HADS)), symptoms, pulmonary function test and 6-min walk test were collected. We included 218 patients (mean age 59.9 (95% CI: 58.2, 61.7), 59% males). Fatigue, dyspnea and impaired concentration were the most prevalent symptoms at follow-up. Using FAS, 47% reported mild-to-moderate fatigue and 18% severe fatigue. Mean HADS was 7.9 (95% CI: 6.9, 8.9). FAS was correlated to HADS (β = 0.52 (95% CI: 0.44, 0.59, p < 0.001)). Mean DLCO was 80.4% (95% CI: 77.8, 83.0) and 45% had DLCO ˂ 80%. Mean DLCO was significantly reduced in patients treated in the ICU (70.46% (95% CI 65.13, 75.79)). The highest FAS and HADS were seen in patients with the shortest period of hospitalization (2.1 days (95% CI: 1.4, 2.7)) with no need for oxygen. In conclusion, fatigue is a common symptom after hospitalization for COVID-19 and ICU treatment is associated to decreased diffusion capacity.

We have developed a simple and robust method for ACE genotyping and determined genotype-specific reference intervals for s-ACE concentrations in the Danish population. The new reference intervals may increase the value of s-ACE measurements.

We estimate the direct costs per TB patient to be €10,509. TB patients and their households are characterized by increasingly lower employment income, lower employment rate, and higher dependency on public transfer, but the socio/economic deterioration is rather a risk factor for TB than a direct consequence of the disease.

Background: Although chronic obstructive pulmonary disease (COPD) is one of the leading causes of morbidity and mortality globally, several studies have shown little awareness of COPD in the general population. The awareness of COPD in the Scandinavian countries is, however, sparsely investigated. Objective: The aim of this study was to explore the awareness in the general Danish population of smoking-related health risks and symptoms related to COPD and attitudinal factors concerning smoking. Design: Adults aged 18 years or older were randomly selected to reflect the background population. An Internet-based questionnaire was conducted in January–February 2015. Results: A total of 1002 answered the questionnaire (515 males; 487 females). In total, 17.7% were current smokers (men: 15.5%–women: 19.9%). More smokers and ex-smokers knew the symptoms of COPD compared to never-smokers (p < 0.001). Ex-smokers had undergone more pulmonary function tests than smokers and never-smokers (p < 0.001) and significantly more men than women who had undergone pulmonary function test.Ex-smokers were more likely to rate cancer as the most feared disease (p = 0.026) than the smokers. Of the smokers, 28% did not regard COPD as a deadly disease and significantly more smokers than ex-/never-smokers believed that smoking cessation should not be mandatory before treatment of COPD and asthma (p < 0.001). Conclusion: Overall, smokers, ex-, and never-smokers had little knowledge of COPD regarding aetiology, symptoms, and severity thus emphasizing the necessity of early detection of COPD and more focus on spirometry in general practice, especially amongst smokers.There is a great discrepancy between the attitude of smokers and ex-/never-smokers towards mandatory smoking cessation before receiving treatment of smoking-related diseases.
