ABSTRACT
One of the most prevalent influenceable risk factors for poor cardiovascular outcome is arterial hypertension.This is a prospective analysis of liver transplant recipients in which 24-hour blood pressure (BP) measurement was performed. The primary aim was to identify post-LT (liver transplantation) patients without a history of arterial hypertension who meet the criteria for arterial hypertension using 24-hour BP monitoring. Secondary objectives were to determine how many patients with known treated arterial hypertension had suboptimal BP control. The group included 88 patients (men, 52.3%, history of arterial hypertension group: n=56, no history of arterial hypertension group: n=32) with an average age at the time of measurement of 62.4 years±11. The average time since LT at the time of measurement was 45.2 months. De novo arterial hypertension using 24-hour BP monitoring was diagnosed in 28%. Hypertonic changes in the fundus oculi were confirmed as predictor for suboptimally controlled hypertension [OR 5,1265, p=0.0279]. On the other hand, male sex [OR 3.1840, p=0.0311], together with age [OR 1.3347, p=0.0153] and waist circumference [OR 4.3490, p=0.0418] predicted the need of intensification of antihypertensive treatment. Male sex, age and waist circumference should increase the index of suspicion and lead to zoom-in on a possibility of poorly controlled blood pressure. Where automated blood pressure monitoring is unavailable, regular examination of the fundus could serve as an available surrogate marker of suboptimally controlled arterial hypertension (Tab.6, Fig. 1, Ref. 36).

ABSTRACT
Direct comparison of key physical and chemical-engineering properties of two representative matrices for multipurpose immobilisations was performed for the first time. Polyvinyl alcohol lens-shaped particles LentiKats® and polyelectrolyte complex microcapsules were characterised by advanced techniques with respect to the size distribution of the particles, their inner morphology as revealed by fluorescent probe staining, mechanical resistance, size-exclusion properties, determination of effective diffusion coefficient and environmental scanning electron microscope imaging. While spherical polyelectrolyte complex microcapsules composed of a rigid semipermeable membrane and a liquid core are almost uniform in shape and size (diameter of 0.82 mm; RSD = 5.6 %), lens-shaped LentiKats® are characterised by wider size distribution (diameter of 3.65 mm; RSD = 10.3 % and height of 0.341 mm; RSD = 32.3 %) and showed the same porous structure throughout their whole volume at the mesoscopic (micrometre) level. Despite differences in their inner structure and surface properties, the pore diameter of â¼ 2.75 nm for regular polyelectrolyte complex microcapsules and â¼ 1.89 nm for LentiKats® were similar. These results were used for mathematical modelling, which provided the estimates of the effective diffusion coefficient of sucrose. This value was 1.67 × 10(-10) m(2) s(-1) for polyelectrolyte complex microcapsules and 0.36 × 10(-10) m(2) s(-1) for LentiKats®. Recombinant cells Escherichia coli-overexpressing enzyme cyclopentanone monooxygenase were immobilised in polyelectrolyte complex microcapsules and LentiKats® for comparison of their operational stability using model Baeyer-Villiger oxidation of (±)-cis-bicyclo [3.2.0] hept-2-en-6-one to regioisomeric lactones as important chiral synthons for potential pharmaceuticals. Both immobilisation matrices rendered high operational stability for whole-cell biocatalyst with no reduction in the biooxidation rate over 18 repeated reaction cycles.
