Concentration factors and biological half-lives for the dynamic modelling of radionuclide transfers to marine biota in the English Channel.

Sci Total Environ 2021 Jun 5;791:148193. Epub 2021 Jun 5.

Laboratoire de Radioécologie de Cherbourg-Octeville, Institut de Radioprotection et de Sûreté Nucléaire/PSE-ENV/SRTE, Rue Max Pol Fouchet, BP10, 50130 Cherbourg-en-Cotentin, France. Electronic address:

The biokinetics of radionuclide transfers to biota in the marine environment can be modelled using two parameters, specific to both each element/radionuclide and biota. The Concentration Factor (CF) reflects the ratio between the activity concentrations in the biota and the surrounding seawater in steady state. The biological half-life (tb) characterizes depuration kinetics for the radionuclide from the biota. Read More

Echocardiography during the coronavirus disease 2019 pandemic - the impact of the vaccination program. A 2021 update of the expert opinion of the Working Group on Echocardiography of the Polish Cardiac Society.

Kardiol Pol 2021 ;79(5):595-603

Department of Congenital Heart Disease, National Institute of Cardiology, Warszawa, Poland.

The coronavirus disease 2019 (COVID-19) pandemic resulted in an urgent need to reorganize the work of echocardiography laboratories in order to ensure the safety of patients and the protection of physicians, technicians, and other staff members. In the previous Expert Opinion of the Working Group on Echocardiography of Polish Cardiac Society we provided recommendations for the echocardiographic services, in order to ensure maximum possible safety and efficiency of imagers facing epidemic threat. Now, with much better knowledge and larger experience in treating COVID-19 patients and with introduction of vaccination programs, we present updated recommendations for performing transthoracic and transesophageal examinations, including information on the potential impact of personnel and the patient vaccination program, and growing numbers of convalescents on performance of echocardiographic laboratories, with the goal of their ultimate reopening.

Platelet function in patients undergoing surgical and transcatheter aortic valve replacement: a comparative study.

Kardiol Pol 2021 ;79(5):554-561

1st Department of Cardiology, Poznan University of Medical Sciences, Poznań, Poland.

Background: Intervention-induced platelet hypercoagulability may pose a risk of serious adverse events for patients.

Aims: This study aimed to assess whether surgical and transcatheter aortic valve replacement (SAVR and TAVR) differ in periprocedural platelet activity.

Methods: The total number of 24 patients with a mean age (SD) of 71 (13) years who underwent SAVR (n = 12) or TAVR (n = 12) were recruited for the study. Read More

Neuron-specific enolase concentrations for the prediction of poor prognosis of comatose patients after out-of-hospital cardiac arrest: an observational cohort study.

Kardiol Pol 2021 ;79(5):546-553

Department of Cardiology and Internal Diseases, Military Institute of Medicine, Warszawa, Poland.

Background: Neuron-specific enolase (NSE) is a biomarker for neurological outcomes after cardiac arrest with the most evidence collected thus far; however, recommended prognostic cutoff values are lacking owing to the discrepancies in the published data.

Aims: The aim of the study was to establish NSE cutoff values for prognostication in the environment of a cardiac intensive care unit following out-of-hospital cardiac arrest (OHCA).

Methods: A consecutive series of 82 patients admitted after OHCA were enrolled. Read More

Longitudinal assessment of cardiac function in extremely low birth weight children at 7 and 11 years of age: implications for adult medicine.

Kardiol Pol 2021 ;79(5):539-545

Department of Pediatrics, Jagiellonian University Medical College, Kraków, Poland.

Background: The long-term impact of extreme prematurity on cardiac structure and function has not been fully evaluated.

Aims: The aim of the study was to assess cardiac condition at 11 years of age in a local cohort of extremely low birth weight (ELBW) children born between 2002 and 2004 and to compare it to a previous study in the same group at 7 years of age.

Methods: Sixty-four children with ELBW (median birth weight of 890 g) and 36 children born at full term underwent echocardiography and physical examination. Read More

Is the extent of left atrial fibrosis associated with body mass index in patients undergoing pulmonary vein isolation for atrial fibrillation?

Kardiol Pol 2021 ;79(5):531-538

Faculty of Medicine, J.J. Strossmayer University in Osijek, Osijek, Croatia.

Background: Left atrial (LA) fibrosis is associated with a higher rate of recurrence of atrial fibrillation (AF) after pulmonary vein isolation (PVI). Body mass index (BMI) is strongly associated with the prevalence of AF, but there is insufficient data about the association between BMI and LA fibrosis.

Aims: The aim of the study was to examine the association between LA fibrosis and BMI in patients with AF undergoing PVI. Read More

Atrial fibrillation risk scores to evaluate left atrial substrate based on voltage analysis in long-standing persistent type of arrhythmia.

Kardiol Pol 2021 ;79(5):525-530

Cardiology Department, Pomeranian Medical University, Szczecin, Poland.

Background: Pre-ablation identification of left atrial (LA) low voltage areas (LVA) among long-standing persistent atrial fibrillation (LSPAF) population remains challenging.

Aims: The aim of the study was to analyze the potential of selected scores originally developed to assess arrhythmia recurrences, thromboembolic complications, or progression from paroxysmal to persistent AF to predict the presence of LA-LVA in LSPAF patients.

Methods: One hundred and fifty-two patients underwent pulmonary vein isolation followed by high-density-high-resolution LA voltage mapping. Read More
