    • To identify new risk variants for cutaneous basal cell carcinoma, we performed a genome-wide association study of 16 million SNPs identified through whole-genome sequencing of 457 Icelanders. We imputed genotypes for 41,675 Illumina SNP chip-typed Icelanders and their relatives. In the discovery phase, the strongest signal came from rs78378222[C] (odds ratio (OR) = 2.36, P = 5.2 × 10(-17)), which has a frequency of 0.0192 in the Icelandic population. We then confirmed this association in non-Icelandic samples (OR = 1.75, P = 0.0060; overall OR = 2.16, P = 2.2 × 10(-20)). rs78378222 is in the 3' untranslated region of TP53 and changes the AATAAA polyadenylation signal to AATACA, resulting in impaired 3'-end processing of TP53 mRNA. Investigation of other tumor types identified associations of this SNP with prostate cancer (OR = 1.44, P = 2.4 × 10(-6)), glioma (OR = 2.35, P = 1.0 × 10(-5)) and colorectal adenoma (OR = 1.39, P = 1.6 × 10(-4)). However, we observed no effect for breast cancer, a common Li-Fraumeni syndrome tumor (OR = 1.06, P = 0.57, 95% confidence interval 0.88-1.27).

  • Smoking, stages of change and decisional balance in Iceland and Sweden
  • 2011
  • Ingår i: The Clinical Respiratory Journal. - 1752-6981. ; 5:2, s. 76-83
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Smoking remains a significant health problem. Smoking interventions are important but selection of successful quitters can be difficult. Objective: To characterise smokers with emphasis on two constructs of the transtheoretical model, the stages of change and decisional balance. Methods: A random sample from adults aged 40 and over in Reykjavik, Iceland, and Uppsala, Sweden. Smokers were defined as being in the stage of pre-contemplation (not thinking of quitting within the next 6 months), contemplation (thinking of quitting within the next 6 months) or preparation (thinking of quitting within the next 30 days, having managed to quit for at least 24 h within the last 12 months). Results: A total of 226 participants were smokers: 72 (32%) were in the pre-contemplation stage, 126 (56%) in the contemplation stage and 28 (12%) in the preparation stage. A younger age, higher body mass index (BMI) and higher educational level were significantly related to being in a more advanced stage. A significant association was observed between decisional balance and stages of change such that decreased importance of the positive aspects of smoking and increased importance of the negative aspects of smoking were independently associated with an increased readiness to quit. Conclusion: The motivated smoker is likely to be young and educated with an above average BMI. A smoker in the contemplation stage is likely to maintain the negative aspects of smoking at a high level. Decreasing the value of the pros of smoking may facilitate the shift towards the stage of preparation.
