asthmatic patients in comparison to controls. The differences in miRNA expression were mainly similar in asthmatics with and without AR. With regard to asthma severity, a trend of increased miRNA expression in persistent asthma was seen, whereas the downregulation of certain miRNAs was most distinct in nonpersistent-asthma patients. Conclusions: Differences in miRNA expression in the nasal mucosa of subjects with long-term asthma and AR can be seen also when no markers of Th2-type inflammation are detected. Asthma severity had only a minor impact on miRNA expression.

Our results suggest that microRNAs miR-155, miR-205, miR-498, and let-7e may be important in the allergic inflammation present in nasal mucosa. Regarding NAR, our findings support the view that mechanisms other than inflammation are pivotal.

We report an outbreak of invasive pneumococcal disease and pneumococcal pneumonia among shipyard workers, in Turku, Southwest Finland. In total, 31 confirmed and six probable cases were identified between 3 May and 28 November 2019. Streptococcus pneumoniae serotypes 12F, 4 and 8 were isolated from blood cultures of 25 cases. Occupational hygiene measures and vaccination of ca 4,000 workers are underway to control the outbreak at the shipyard.

We studied, whether asthma diagnosed in childhood or early adulthood affects work ability 20 years later. We used Finnish Defence Force registers, 1986-1990, to select: (1) conscripts with asthma to represent a mild/moderate asthma group (n=485), (2) asthmatics who were exempted from military service to represent a relatively severe asthma group (n=393) and (3) a control group (n 1500) without asthma. A questionnaire consisting of validated questions on asthma and work ability was sent out in 2009. A total of 54% of the men in the first study group, 44% of those in the second study group and 44% of the controls answered. The mean age of the participants was 41 (range 37-51). Self-assessed current work ability compared with lifetime best had decreased in 28.9% of the first asthma group, in 31.1% of the second asthma group, and in 19.7% of the controls (p = 0.0007). Current smoking (OR 2.5), only basic education (OR 2.6), being a manual worker (OR 2.7) and current severe asthma (OR 3.8) associated most strongly with decreased work ability among the asthmatics. Both mild and more severe asthma at the age of around 20 seems to be associated with reduced work ability in 40-year-old males.
