BACKGROUND The proportion of proton pump inhibitor users on long-term therapy who can discontinue proton pump inhibitor (PPI) medication without developing symptoms is unknown. AIM To determine the proportion of patients on long-term PPI therapy who are able to discontinue PPIs without developing symptoms. METHODS Patients on long-term PPIs, without a(More)
BACKGROUND The Emergency Departments (EDs) reorganization process in Denmark began in 2007 and includes creating a single entrance for all emergency patients, establishing triage, having a specialist in the front and introducing the use of electronic overview boards and electronic patient files. The aim of this study was to investigate the quality of acute(More)
Aims The risk of incident atrial fibrillation (AF) can be estimated by clinical parameters in the Framingham AF risk model. Elevated N-terminal pro-B-type natriuretic peptide (NT-proBNP) and increased rate of premature atrial contractions (PACs) have been shown to be associated with AF, but the additive value of both of these biomarkers in the Framingham AF(More)
INTRODUCTION/PURPOSE Fat metabolism and muscle adaptation was investigated in six older trained men (age, 61 ± 4 yr; V˙O2max, 48 ± 2 mL·kg·min) after repeated prolonged exercise). METHODS A distance of 2706 km (1681 miles) cycling was performed over 14 d, and a blood sample and a muscle biopsy were obtained at rest after an overnight fast before and 30 h(More)
BACKGROUND Inflammation plays a major role in the development of atherosclerosis. We wanted to investigate the effects of exercise on high-sensitivity (hs) C-reactive protein (CRP) in subjects who were suspected of having coronary artery disease (CAD). METHODS Blood samples were obtained before, 5 minutes after, and 20 hours after an exercise test in 155(More)
AIMS Severe hypokalaemia can aggravate arrhythmia tendency and prognosis, but less is known about risk of mild hypokalaemia, which is a frequent finding. We examined the associations between mild hypokalaemia and ambulatory cardiac arrhythmias and their prognosis. METHODS AND RESULTS Subjects from the cohort of the 'Copenhagen Holter Study' (n = 671),(More)
BACKGROUND AND PURPOSE Low serum potassium is associated with stroke in populations with cardiovascular disease, hypertension, and diabetes mellitus but has not been studied in a mainly healthy population. We aimed to study the relation between serum potassium and incident stroke and mortality in the Malmö Preventive Project, a large cohort with screening(More)
BACKGROUND AND PURPOSE Stroke is independently associated with the common conditions of hypokalemia and supraventricular ectopy, and we hypothesize that the combination of excessive supraventricular ectopic activity and hypokalemia has a synergistic impact on the prognosis in terms of stroke in the general population. METHODS Subjects (55-75 years old)(More)
Hypertriglyceridaemia is an uncommon cause of acute pancreatitis, accounting for 1-4% of cases. In the case of lipoprotein-lipase mutations, lipid levels may rise to extreme levels during acute pancreatitis. In this case a 29-year-old female was hospitalized several times due to acute pancreatitis. She presented with extreme lipid levels and difficulty in(More)
