A head-to-head comparison of laser vs. powered mechanical sheaths as first choice and second line extraction tools.

Aims: During transvenous lead extraction (TLE) longer dwelling time often requires the use of powered sheaths. This study aimed to compare outcomes with the laser and powered mechanical tools.

Methods And Results: Single-centre data from consecutive patients undergoing TLE between 2012 and 2021 were retrospectively analysed.

Seasonal changes in proportion of cardiac surgeries associated with diabetes, smoking and elderly age.

Background: Seasonal variations in the ambient temperature may affect the exacerbation of cardiovascular diseases. Our primary objective was to evaluate the seasonality of the monthly proportion of cardiac surgeries associated with diabetes, smoking and/or elderly age at a tertiary-care university hospital in East-Central Europe with a temperate climate zone. As a secondary objective, we also assessed whether additional factors affecting small blood vessels (smoking, aging, obesity) modulate the seasonal variability of diabetes.

[Epidemiology of anemia].

Worldwide, the prevalence of anemia is high, and iron deficiency anemia is the fifth most common disorder according to the study called "Global burden of disease". It can be attributed to a number of factors, complex pathomechanisms, and etiology is highly variable in terms of age, gender, and geographical distribution. The prevalence of anemia increases with age.

Differences Between Central Venous and Cerebral Tissue Oxygen Saturation in Anaesthetised Patients With Diabetes Mellitus.

The brain has high oxygen extraction, thus the regional cerebral tissue oxygen saturation (rSO) is lower than the central venous oxygen saturation (ScvO). We hypothesised that diabetes widens the physiological saturation gap between ScvO and rSO (gSO), and the width of this gap may vary during various phases of cardiac surgery. Cardiac surgery patients with (n = 48) and without (n = 91) type 2 diabetes mellitus (T2DM) underwent either off-pump coronary artery bypass (OPCAB) or other cardiac surgery necessitating cardiopulmonary bypass (CPB) were enrolled.

[Diabetes mellitus: endothelial dysfunction and changes in hemostasis].

Diabetes mellitus involves a group of chronic metabolic disorders with elevated blood glucose concentrations. Since this disease needs lifelong treatment and care, the medical and social aspects present major public health concerns and pose a global challenge for health care providers. The number of aged patients with degenerative diseases undergoing surgical procedures is continuously increasing, resulting in an overwhelming dominance of diabetes in the perioperative care.
