The incidence and mortality of refeeding syndrome in older hospitalized patients, based on three different diagnostic criteria: A longitudinal study.

Background & Aims: Refeeding syndrome (RFS) lacks both a global definition and diagnostic criteria. Different diagnostic criteria are used; serum phosphate (traditional criterion (TC)), the Friedli consensus recommendations, and the ASPEN. We investigated the incidence of RFS in older hospitalized patients and the mortality rates in patients with or without RFS using these three different diagnostic criteria.

Admission Serum Calcium Level and Short-Term Mortality After Acute Ischemic Stroke: A Secondary Analysis Based on a Norwegian Retrospective Cohort.

Background: Disturbed serum calcium levels are related to the risk of stroke. However, previous studies exploring the correlation between serum calcium and the clinical outcome of ischemic stroke (IS) have shown inconsistent results.

Object: The study aimed to investigate the relationship between admission serum calcium and 30-day mortality in patients with IS.

Electrolyte outpatient clinic at a local hospital - experience from diagnostics, treatment and follow-up.

Background: Electrolyte imbalances (EI) are common among patients. Many patients have repeated hospitalizations with the same EI without being investigated and treated. We established an electrolyte outpatient clinic (EOC) to diagnose and treat patients with EI to improve symptoms and increase their quality of life (QoL).

Hypokalemia Promotes Arrhythmia by Distinct Mechanisms in Atrial and Ventricular Myocytes.

Rationale: Hypokalemia occurs in up to 20% of hospitalized patients and is associated with increased incidence of ventricular and atrial fibrillation. It is unclear whether these differing types of arrhythmia result from direct and perhaps distinct effects of hypokalemia on cardiomyocytes.

Objective: To investigate proarrhythmic mechanisms of hypokalemia in ventricular and atrial myocytes.

Potassium infusion increases the likelihood of conversion of recent-onset atrial fibrillation-A single-blinded, randomized clinical trial.

Background: The optimal antiarrhythmic management of recent-onset atrial fibrillation (ROAF) or atrial flutter is controversial and there is a considerable variability in clinical treatment strategies. It is not known if potassium infusion has the potential to convert ROAF or atrial flutter to sinus rhythm (SR). Therefore, we aimed to investigate if patients with ROAF or atrial flutter and plasma-potassium levels ≤4.

Acute Dysnatremias - a dangerous and overlooked clinical problem.

Background: Dysnatremias are common electrolyte disturbances with significant morbidity and mortality. In chronic dysnatremias a slow correction rate (<10 mmol/L/24 h) is indicated to avoid neurological complications. In acute dysnatremias (occurring <48 h) a rapid correction rate may be indicated.

Electrolyte imbalances in an unselected population in an emergency department: A retrospective cohort study.

Background: Although electrolyte imbalances (EIs) are common in the emergency department (ED), few studies have examined the occurrence of such conditions in an unselected population.

Objectives: To investigate the frequency of EI among adult patients who present to the ED, with regards to type and severity, and the association with age and sex of the patient, hospital length of stay (LOS), readmission, and mortality.

Methods: A retrospective cohort study.

Exercise-induced rhabdomyolysis - a patient series.

Background: No guidelines are available for the treatment and follow up of exercise-induced rhabdomyolysis. The purpose of this study was to describe the treatment, complications and follow-up of patients with exercise-induced rhabdomyolysis at Diakonhjemmet Hospital.

Material And Method: A retrospective observational study from 2011 up to and including 2015 of patients with exercise-induced rhabdomyolysis ≥ 18 years and with creatine kinase > 5 000 IU/l.
