- Little is known about the characteristics and treatments of patients with severe asthma across Europe, but both are likely to vary. This is the first study in the European Respiratory Society Severe Heterogeneous Asthma Research collaboration, Patient-centred (SHARP) Clinical Research Collaboration and it is designed to explore these variations. Therefore, we aimed to compare characteristics of patients in European severe asthma registries and treatments before starting biologicals.This was a cross-sectional retrospective analysis of aggregated data from 11 national severe asthma registries that joined SHARP with established patient databases.Analysis of data from 3236 patients showed many differences in characteristics and lifestyle factors. Current smokers ranged from 0% (Poland and Sweden) to 9.5% (Belgium), mean body mass index ranged from 26.2 (Italy) to 30.6 kg·m−2 (the UK) and the largest difference in mean pre-bronchodilator forced expiratory volume in 1 s % predicted was 20.9% (the Netherlands versus Hungary). Before starting biologicals patients were treated differently between countries: mean inhaled corticosteroid dose ranged from 700 to 1335 µg·day−1 between those from Slovenia versus Poland when starting anti-interleukin (IL)-5 antibody and from 772 to 1344 µg·day−1 in those starting anti-IgE (Slovenia versus Spain). Maintenance oral corticosteroid use ranged from 21.0% (Belgium) to 63.0% (Sweden) and from 9.1% (Denmark) to 56.1% (the UK) in patients starting anti-IL-5 and anti-IgE, respectively.The severe asthmatic population in Europe is heterogeneous and differs in both clinical characteristics and treatment, often appearing not to comply with the current European Respiratory Society/American Thoracic Society guidelines definition of severe asthma. Treatment regimens before starting biologicals were different from inclusion criteria in clinical trials and varied between countries.

- Background: The European Randomized study of Screening for Prostate Cancer (ERSPC) has previously demonstrated that prostate-specific antigen (PSA) screening decreases prostate cancer (PCa) mortality. Objective: To determine whether PSA screening decreases PCa mortality for up to 16 yr and to assess results following adjustment for nonparticipation and the number of screening rounds attended. Design, setting, and participants: This multicentre population-based randomised screening trial was conducted in eight European countries. Report includes 182 160 men, followed up until 2014 (maximum of 16 yr), with a predefined core age group of 162 389 men (55-69 yr), selected from population registry. Outcome measurements and statistical analysis: The outcome was PCa mortality, also assessed with adjustment for nonparticipation and the number of screening rounds attended. Results and limitations: The rate ratio of PCa mortality was 0.80 (95% confidence interval [CI] 0.72-0.89, p < 0.001) at 16 yr. The difference in absolute PCa mortality increased from 0.14% at 13 yr to 0.18% at 16 yr. The number of men needed to be invited for screening to prevent one PCa death was 570 at 16 yr compared with 742 at 13 yr. The number needed to diagnose was reduced to 18 from 26 at 13 yr. Men with PCa detected during the first round had a higher prevalence of PSA >20 ng/ml (9.9% compared with 4.1% in the second round, p < 0.001) and higher PCa mortality (hazard ratio = 1.86, p < 0.001) than those detected subsequently. Conclusions: Findings corroborate earlier results that PSA screening significantly reduces PCa mortality, showing larger absolute benefit with longer follow-up and a reduction in excess incidence. Repeated screening may be important to reduce PCa mortality on a population level. Patient summary: In this report, we looked at the outcomes from prostate cancer in a large European population. We found that repeated screening reduces the risk of dying from prostate cancer. (C) 2019 Published by Elsevier B.V. on behalf of European Association of Urology.

- Background To describe the variation in PSA level by age group and screening round in the ERSPC centres and the variation in cancer detection rates in relation to the underlying prostate cancer incidence. Methods Individual data on men invited for the first and second screening rounds according to protocol (excluding early recalls and interval cancers) were obtained from the central database of the ERSPC (cut-off date 31st December 2006). Data were compared between and within centres for the core age group (55–69 at entry). The cancer detection rate (CDR) was compared with the expected background prostate cancer incidence rate in the absence of screening adjusted for the incidence rate in non-attenders and the control arm (IRS). Results Mean PSA values in the age groups 55–59 years and 65–69 years showed little variation by centre, except for the Dutch centre, where an increase from 1.6 to 1.8 ng/ml and a decline from 2.9 to 2.5 ng/ml was observed, respectively. Most tumours were detected at the PSA range 4.0–9.9 ng/ml, with a shift to more cancer detection at 3.0–3.9 ng/ml in the second screening round. There was high variability in the CDR between the centres in both the first (16–46 per 1000) and the second screening rounds (14–50 per 1000). Although the ratio CDR/IRS was less variable, it is somewhat lower in Italy and Switzerland (12 and 14,respectively) and higher in the Netherlands (28), than in most other centres and in Belgium the ratio increased markedly, from 20 to 44 between the first and second rounds. Conclusion There was no clear evidence of a relationship between the underlying incidence and mean PSA levels at screening or the cancer detection rate.
