Subclinical Atherosclerosis Progression in Low-Risk, Middle-Aged Adults: Carotid Leads Femoral in IMT Increase but Not in Plaque Formation.

Unlabelled: This study investigated subclinical atherosclerosis progression in low-risk, middle-aged adults (N = 141; a mean age of 49.6 ± 4.7 years) using a 5-year ultrasound follow-up.

Detection of SEN virus in the general population and different risk groups in Slovakia.

Sera of 426 adult persons were examined to assess the prevalence of SEN virus (SENV) infection in Slovakia and to determine the importance of different risk factors for parenteral transmission. SENV prevalence was determined by the PCR method using primers of SENV-D and SENV-H strains. Positive results were found in 10 of 37 patients with acute hepatitis of unknown etiology, 7 of 38 with acute hepatitis B, 17 of 44 with chronic hepatitis B, 29 of 102 with chronic hepatitis C, 36 of 72 hemodialysis patients, 2 of 33 health care workers and 24 of 100 persons from the control group.

Prevalence, epidemiological aspects and clinical importance of TT virus infection in Slovakia.

The aim of the study was to assess the prevalence, clinical impact and importance of different risk factors of transmission of TTV infection in Slovakia using two PCR methods. Sera of 426 adult persons were examined. TTV DNA was identified by PCR using primers from N22 and untranslated region (UTR) respectively.

[High resolution electrocardiography of P-wave signals in clinical cardiology].

Signal-averaged electrocardiography of the QRS complex detects presence of late potentials which represent significant arrhythmogenic marker responsible for increased risk of life-threatening ventricular arrhythmias especially in post myocardial infarction patients. The P wave signal-averaged electrocardiography has been designed to predict development of atrial fibrillation in different populations of patients. Many P wave signal-averaging methodological procedures have been developed.
