Atmospheric fallout radionuclides in peatland from Southern Poland.

Two peat profiles were collected in a peat bog located in Southern Poland and their geochronology were determined using Pb, Pu and Cs radiometric techniques. The Pb chronologies were established using the constant rate of supply model (CRS) and are in good agreement with the Pu isotopes and Cs time markers. Maximum activities of Pu isotopes were found at a depth corresponding to the early 1960s, which is the period characterized by the maximum nuclear weapon tests.

Novel approaches for prevention of stroke related to transcatheter aortic valve implantation.

Transcatheter aortic valve implantation (TAVI) has emerged as a therapeutical option in patients with aortic stenosis. The methodology has evolved rapidly throughout the last decade. Nowadays, peri-procedural circulatory support, surgical vascular access, general anesthesia and mechanical ventilation are mainly reserved for selected patients.

Cognitive trajectory after transcatheter aortic valve implantation.

Background: Transcatheter aortic valve implantation (TAVI) is known to be associated with silent cerebral injury, which could contribute to cognitive impairment. Considering its increasing use, thorough longitudinal investigation of cognitive trajectory after TAVI is pivotal.

Methods And Results: Repeatable battery for the assessment of neuropsychological status was performed before (E1), 3 days (E2), 3 months (E3), 1 (E4) year, and 2 years (E5) after TAVI.

Prognostic value of cerebral injury following transfemoral aortic valve implantation.

Aims: To evaluate the impact of serological, imaging and clinical measures of cerebral injury on patient self-sufficiency and survival after transcatheter aortic valve implantation (TAVI).

Methods And Results: Before and three days after TAVI, neuron-specific enolase (NSE), cerebral diffusion-weighted magnetic resonance imaging (DW-MRI) and neurological performance utilising National Institutes of Health Stroke Scale (NIHSS) were assessed. Self-sufficiency was determined with established score systems (instrumental activities of daily living score, Barthel Index).
