Utilization and outcomes of tracheostomies in the intensive care unit in Iceland in 2007-2020: A descriptive study.

Background: Tracheostomies are commonly utilized in ICU patients due to prolonged mechanical ventilation, upper airway obstruction, or surgery in the face/neck region. However, practices regarding the timing of placement and utilization vary. This study provides a nationwide overview of tracheostomy utilization and outcomes in the ICU over a 14-year period.

Association of Genetically Predicted Lipid Levels With the Extent of Coronary Atherosclerosis in Icelandic Adults.

Importance: Genetic studies have evaluated the influence of blood lipid levels on the risk of coronary artery disease (CAD), but less is known about how they are associated with the extent of coronary atherosclerosis.

Objective: To estimate the contributions of genetically predicted blood lipid levels on the extent of coronary atherosclerosis.

Design, Setting, And Participants: This genetic study included Icelandic adults who had undergone coronary angiography or assessment of coronary artery calcium using cardiac computed tomography.

Co-regulatory networks of human serum proteins link genetics to disease.

Proteins circulating in the blood are critical for age-related disease processes; however, the serum proteome has remained largely unexplored. To this end, 4137 proteins covering most predicted extracellular proteins were measured in the serum of 5457 Icelanders over 65 years of age. Pairwise correlation between proteins as they varied across individuals revealed 27 different network modules of serum proteins, many of which were associated with cardiovascular and metabolic disease states, as well as overall survival.

[Heart failure among elderly Icelanders: Incidence, prevalence, underlying diseases and long-term survival].

Introduction: Heart failure (HF) is a common and a serious condition that predominantly affects elderly people. On the basis of the left ventricular ejection fraction (EF) it can be divided into HF with reduced or preserved ejection fraction (HFrEF and HFpEF, respectively). The goal of this study was to investigate the prevalence and incidence of HF among elderly Icelanders, explore underlying diseases and estimate the effect of HF on overall survival.

Prevalence of heart failure in the elderly and future projections: the AGES-Reykjavík study.

Objectives: To assess the prevalence of heart failure (HF) in a randomly selected study population of elderly individuals representing the general population of Iceland. Furthermore, to project the number of individuals likely to have HF in the future.

Design: Baseline characteristics and clinical data from 5706 individuals who participated in the population based AGES-Reykjavik Study and gave their informed consent were used.
