On 30 January 2020, the disease covid-19 was declared by the World Health Organization to be an international threat to human health and on 11 March 2020, the outbreak was declared a pandemic. The aim of this study was to analyse policy strategies developed by the five Nordic countries during the first 3 months of the pandemic from a health promotion perspective in order to identify Nordic responses to the crisis. Although the Nordic countries have a long tradition of co-operation as well as similar social welfare policies and legislation, each country developed their own strategies towards the crisis. The strategies identified were analysed from a health promotion perspective emanating from five principles: intersectorality, sustainability, equity, empowerment and a lifecourse perspective. Denmark, Finland and Norway had lockdowns to varying degrees, whereas Sweden and Iceland had no lockdowns. Iceland implemented a test and tracking strategy from the very beginning. All countries based their recommendations and restrictions on appeals to solidarity and trust in institutions and fellow citizens. The analysis showed that the strategies in all countries could be related to health promotion principles with some differences between the countries especially regarding equity and sustainability. The Nordic governments took responsibility for protecting their citizens by developing policy strategies based on restrictions and recommendations congruent with the principles of health promotion. The findings also identified issues that will pose challenges for future pandemic strategies., (© The Author(s) 2022. Published by Oxford University Press. All rights reserved.

Gastric cancer is a serious health problem worldwide, with particularly high prevalence in eastern Asia. Genome-wide association studies (GWAS) in Asian populations have identified several loci that associate with gastric cancer risk. Here we report a GWAS of gastric cancer in a European population, using information on 2,500 population-based gastric cancer cases and 205,652 controls. We found a new gastric cancer association with loss-of-function mutations in ATM (gene test, P = 8.0 × 10(-12); odds ratio (OR) = 4.74). The combination of the loss-of-function variants p.Gln852*, p.Ser644* and p.Tyr103* (combined minor allele frequency (MAF) = 0.3%) also associates with pancreatic and prostate cancers (OR = 3.81 and 2.18, respectively) and gives an indication of risk of breast and colorectal cancers (OR = 1.82 and 1.97, respectively). Cancers in those carrying loss-of-function ATM mutations are diagnosed at a significantly earlier age than in non-carriers. Our results confirm an association between gastric cancer in Europeans and three loci previously reported in Asians, MUC1, PRKAA1 and PSCA, refine the association signal at PRKAA1 and support a pathogenic role for the tandem repeat identified in MUC1.
