Prevalence of hypertension, which is the most common risk factor for cardiovascular disease in elderly people, increases with age. The aim of the study was to investigate the association between diet and blood pressure in elderly Icelanders, with focus on cod liver oil, and to compare their diet to dietary guidelines. ⋯ The results indicate that intake of cod liver oil is associated with lower blood pressure among elderly people and may therefore have beneficial effects on health. A notable proportion of participants was at risk of vitamin D, vitamin B6, iodine, and iron deficiency.

Sudden cardiac death in young athletes is relatively uncommon and is usually caused by occult underlying cardiovascular disease. Studies have indicated that preparticipation screening may reduce the incidence of sudden death. Our aim was to study the feasibility of standardized preparticipation screening in young competitive Icelandic athletes. The prevalence of risk factors was studied in order to evaluate how often further examination is indicated and to assess possible costs. ⋯ Symptoms associated with cardiac disease are frequently described among young athletes. Abnormal ECG was commonly found. Further examination with echocardiography may be indicated in one of every four athletes screened.

Comparative Study
[The impact of lung diseases, smoking and e-cigarette use on the severity of COVID-19 illness at diagnosis].
The COVID-19 pandemic has caused public health and economic turmoil across the globe. Severe COVID-19 disease most often presents with pneumonia and complications in acutely ill patients often stem from the lungs. The associations of lung disease, smoking and e-cigarette use with the incidence and severity of COVID-19 are unclear on a population level. ⋯ The age distribution and prevalence of lung disease and their risk factors are described in the context of COVID-19 incidence and symptom severity in a whole-nation cohort of Icelanders. The cohort is younger and had less severe symptoms than in many previosly published studies of COVID-19. Interestingly, the prevalences of smoking and e-cigarette use were lower than in the Icelandic general population and they were not associated with symptom severity at diagnosis. To conclude, the results presented here indicate that underlying lung diseases are prevalent among people with severe COVID-19 symptoms but fail to demonstrate an association between cigarette smoking or e-cigarette smoking with COVID-19 severity.

Self-expandable metal stents (SEMS) are a known treatment option for obstruction due to colorectal cancer. The objective of this project was to estimate the usage of such stents in Iceland between 2000-2018. We evaluated the number of patients who received the stent as a bridge to surgery (BtoS) or as a palliative therapy (PT) and evaluated complication rate and the technical and clinical success rate. ⋯ SEMS served as BtoS with resection and primary anastomosis for the majority of patients in the BtoS group. For a majority of patients in the PT group, SEMS could be used to avoid surgery. The perforation rate was relatively high. Information on techincal and clinical success was poorly recorded. Because of the retrospective nature of the study and the small population size all results should be interpreted with caution.
