Development of a prognostic model of COVID-19 severity: a population-based cohort study in Iceland.

Background: The severity of SARS-CoV-2 infection varies from asymptomatic state to severe respiratory failure and the clinical course is difficult to predict. The aim of the study was to develop a prognostic model to predict the severity of COVID-19 in unvaccinated adults at the time of diagnosis.

Methods: All SARS-CoV-2-positive adults in Iceland were prospectively enrolled into a telehealth service at diagnosis.

[Ablation of ganglionated plexi to treat symptomatic parasympathetic induced atrioventricular block].

According to clinical guidelines a symptomatic atrioventricular block (AV block) is treated with a pacemaker. For young individuals such a therapy can be difficult due to possible long term complications such as infections, lead disruptions and pacemaker induced cardiomyopathy. We describe a twenty year old man with recurrent syncopes due to intermittent parasympathetic caused AV block of grade 2.

Clinical spectrum of coronavirus disease 2019 in Iceland: population based cohort study.

Objective: To characterise the symptoms of coronavirus disease 2019 (covid-19).

Design: Population based cohort study.

Setting: Iceland.

Red blood cell utilization and transfusion triggers in patients diagnosed with chronic lymphocytic leukaemia in Iceland 2003-2016.

Background And Objectives: Revised Icelandic guidelines proposed a restrictive haemoglobin (Hb) threshold of 70 g/l for red blood cell (RBC) transfusions in general, but 100 g/l for malignancies/bone marrow suppression. Chronic lymphocytic leukaemia (CLL) is frequently complicated by anaemia. The objective was to investigate RBC transfusion practices in CLL.
