Myocardial Blood Flow Determination From Contrast-Free Magnetic Resonance Imaging Quantification of Coronary Sinus Flow.

Background: Determination of myocardial blood flow (MBF) with MRI is usually performed with dynamic contrast enhanced imaging (MBF ). MBF can also be determined from coronary sinus blood flow (MBF ), which has the advantage of being a noncontrast technique. However, comparative studies of MBF and MBF in large cohorts are lacking.

Silent atrial fibrillation detected by home-monitoring: Cardiovascular disease and stroke prevention in patients with diabetes.

Objective: Patients with silent and undiagnosed paroxysmal atrial fibrillation and flutter (AF) have increased risk of ischemic stroke. Patients with diabetes have a higher risk of both AF and ischemic stroke compared to patients without diabetes. Our aim was to investigate the prevalence of silent AF in patients with diabetes in an outpatient cohort and to identify the possible risk factors associated with AF.

Validation of the Danish National Tympanostomy Tube Insertion Questionnaires.

Introduction: The objective of the present study was to validate two questionnaires (the Danish National Tympanostomy Tube Insertion Questionnaires (DANTIQ)) intended for use by the DØNHO database in the investigation of the effect of tympanic tube (TT) insertion on ear-related symptoms and the adherence of ear, nose and throat (ENT) specialists in Danish private practice to the Danish National Clinical Guideline on treatment of otitis media (OM) with TT insertion using electronic patient-reported outcome (ePRO) data.

Methods: The content validity of the questionnaires was assessed through discussion in a group of four active ENT specialists. Face and content validity analyses were conducted using data from semi-structured, single-person interviews with nine subjects.

Primary and secondary mucosal melanoma of the small intestine - a clinical, pathological, and genetic nationwide survey of Danish patients between 1980 and 2014.

The aim of this study was to describe the epidemiology, symptomatology, pathology, genetics, and treatment of primary and metastatic small intestine melanoma in a national Danish cohort. All Danish patients diagnosed with small intestinal melanoma during the period 1980-2014 were included. For each patient, clinical data along with available pathology report and tissue was registered.
