Recurrent Infective Endocarditis of the Mitral Valve after Orthotopic Heart Transplantation.

Introduction: Orthotopic heart transplantation is the gold standard for the treatment of advanced heart failure in the absence of contraindications. Infective endocarditis is a rare complication in patients after heart transplantation. The treatment of endocarditis after heart transplantation is challenging since there is a need for ongoing immunosuppression.

Plasmatic apelin shows a promising potential as a screening biomarker for atrial fibrillation.

Objectives: Purpose of this study was to evaluate properties of apelin, a peptide detectable in peripheral blood, for atrial fibrillation (AF) detection in a diverse population of patients covering a broad spectrum from healthy to polymorbid patients.

Background: AF is the most common cardiac arrhythmia with constantly increasing incidence and prevalence. Currently available diagnostic tools do not provide sufficient detection rate.

Association Between Apelin and Atrial Fibrillation in Patients With High Risk of Ischemic Stroke.

Atrial fibrillation (AF) is associated with high risk of stroke preventable by timely initiation of anticoagulation. Currently available screening tools based on ECG are not optimal due to inconvenience and high costs. Aim of this study was to study the diagnostic value of apelin for AF in patients with high risk of stroke.

Molecular Mechanisms, Diagnostic Aspects and Therapeutic Opportunities of Micro Ribonucleic Acids in Atrial Fibrillation.

Micro ribonucleic acids (miRNAs) are short non-coding RNA molecules responsible for regulation of gene expression. They are involved in many pathophysiological processes of a wide spectrum of diseases. Recent studies showed their involvement in atrial fibrillation.

Progressive multifocal leukoencephalopathy - epidemiology, immune response, clinical differences, treatment.

Progressive multifocal leukoencephalopathy (PML) is a severe disease of the central nervous system with very high mortality. It is caused by the JC virus with high seroprevalence, at up to 80%. Development of PML is typically opportunistic, particularly in acquired immunodeficiency syndrome, and usually affects patients with profound immunodeficiency.
