The effects of statins on lipoprotein-associated phospholipase A2 (Lp-PLA2) are controversial, and the present study aimed to investigate whether atorvastatin could reduce Lp-PLA2 in rats with dyslipidemia. ⋯ Atorvastatin treatment is beneficial for reducing the Lp-PLA2 level in rats with dyslipidemia, which may be related to reduced ROCK1 expression in a dose-dependent manner.

Mutations at the DFNA9 locus on chromosome 14q12 are the third most common form of DFNA hearing loss, which is clinically characterized by late onset (in adulthood) progressive sensorineural hearing loss accompanied by vestibular dysfunction. The aim of the study was to search for COCH gene mutations (P51S, V66G, G87W, G88E, V104del, I109N, W117R, A119T, M512T, C542Y) in patients with severe or profound sensorineural hearing loss accompanied by a vestibular lesion. ⋯ No cochlin mutations were found in the group of patients with severe to profound sensorineural hearing impairment accompanied by a vestibular lesion. The COCH gene needs further exploration and analysis of genotype-phenotype correlations.

Patients with sickle cell disease have increased left ventricular size, which is not usually accompanied by changes in systolic function indexes. We assessed echocardiographic abnormalities present in patients with sickle cell anemia (SCA) and compared echocardiographic parameters to other sickle cell diseases (OSCD). ⋯ There was an increase of left ventricular and left atrial sizes in patients with SCA, compared to patients with OSCD, without changes in systolic or diastolic function in both groups. This could be due to the hyperkinetic state due to the more severe anemia in the SCA subjects.

In medical education, Web-based learning is increasingly used as a complement to practical classes. The objective of the study was to perform a comparative analysis of three different forms of e-learning course on emergency medicine in terms of an indicator of knowledge growth and students' satisfaction. ⋯ The study allowed the interactive course to be identified as the most effective method of distance learning among selected ones. Due to the limitations of the study, we conclude that there is a need for further studies on the effectiveness of e-learning in emergency medicine.

The aim of our study was to determine the risk factors for electrical storm (ES) and to assess the impact of ES on the long-term prognosis in patients after myocardial infarction (MI) with an implantable cardioverter-defibrillator (ICD) for secondary prevention of sudden cardiac death (SCD). ⋯ Electrical storm in patients after MI with ICD for secondary prevention is a relatively common phenomenon and has a negative prognostic significance. Myocardial infarction of the inferior wall and the absence of coronary revascularization are predisposing factors for the occurrence of an ES.
