Item type:Publication, Impact of preoperative arterial and venous diameter on achievement of the adequate blood flow in arteriovenous fistula for hemodialysis(Wiley, 2020-06); ; ; ; An arteriovenous fistula (AVF) remains the best choice of vascular access (VA) for hemodialysis (HD). The aim of the study was to determine the factors associated with the achievement of adequate blood flow (BF) of AVFs at the 4th week after creation. Created AVFs in 63 patients with chronic kidney disease (CKD) stage 4/5 and CKD stage 5 on hemodialysis (CKD5D) were analyzed in a prospective study. Doppler ultrasound (DUS) was used for measuring the diameter of the radial artery, the brachial artery and the cephalic vein before AVF creation. The BF of AVF was calculated by DUS at the 4th week after creation and adequate BF was defined as ≥ 600 mL/min. The average age of patients was 61.31 ± 12.9 years. An adequate BF of AVF at the 4th week after creation was achieved in 43.54% of patients. The BF of AVF measured in male patients was significantly higher compared to the BF of AVF obtained in females (576.03 mL/min vs 375.12 mL/min, P = 0.004). The diameter of the blood vessels with achieved adequate BF was significantly larger compared to the diameter of the blood vessels without adequate BF (radial artery: 2.45 mm vs 2.03 mm, P = 0.000; brachial artery: 4.78 mm vs 4.06 mm, P = 0.001 and cephalic vein: 3.12 mm vs 2.83 mm P = 0.018). The gender and the diameter of the blood vessels before AVF creation were significantly associated with achievement of adequate BF of AVF at the 4th week of creation. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Efficacy of Medium Cut-Off Dialyzer and Comparison with Standard High-Flux Hemodialysis(S. Karger AG, 2021-07); ; ; Background: A new medium cut-off (MCO) membranes has been designed to achieve better removal capacities for middle and large middle molecules in hemodialysis (HD) treatment. Aim: The aim of this study was to evaluate the removal efficacy of Theranova® in standard HD in comparison with standard high-flux HD. Methods: Four HD patients (M/F 1/4) were included in 12-week observational pilot study in HD with Theranova® 400 and Theranova® 500 dialyzers. Each patient was assessed 4 times, T0 with high-flux dialyzers, T1 at 1 month, T2 at second month, and T3 at third month, by measuring pre- and post-HD samples of urea, Cr, β2-microglobilin (β2M), myoglobin, albumin, free light chains kappa (FLC-k), and free light chains lambda (FLC-λ). Results: The data showed a higher average removal rate for all the uremic toxins with Theranova® dialyzers for β2M, myoglobin, FLC-k, and FLC-λ (62.7, 56.9, 63.5, and 54.6%, respectively) during the 3 months. Albumin retention was observed and did not change between T0 and T3 (p = 0.379). Conclusion: Compared to high-flux membranes, MCO membranes show greater permeability for middle molecules in midterm report. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Case report: First diagnosis of Fabry disease in North Macedonia in a patient presenting with kidney failure on hemodialysis(Frontiers Media SA, 2024); ; ; Fabry disease is a rare X-linked lysosomal storage disorder caused by α-galactosidase A (α-Gal A) deficiency. Reduced or absent enzyme activity causes progressive lysosomal accumulation of globotriaosylceramide (Lyso-Gb3) in various cells throughout the body to trigger inflammation and fibrosis. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, USE OF ULTRASONOGRAPHY FOR CONFORMATION OF CENTRAL VENOUS CATHETER PLACEMENT FOR HEMODIALYSIS - SINGLE CENTER EXPERIENCE(Faculty of Medicine, Ss Cyril and Methodius University in Skopje, 2022); ; Conformation for safe placement of central venous catheter for hemodialysis and exclusion of pneumothorax is done with chest x ray. However, this procedure is time consuming, so in order to shorten this time several attempts have been tried to use bedside ultrasound. To use bedside ultrasonography to confirm tip location of central venous catheter and rule out pneumothorax. The second aim was to compare these results with plain chest x ray. In 50 patients on hemodialysis central venous catheter were inserted in internal jugular vein or subclavian vein under ultrasound guidance. After insertion, a subxiphoid 4 chamber view was obtained looking to detect turbulence or microbubbles shortly after 10ml saline flush through catheter. Then, ultrasound of the patient's chest was performed to exclude pneumothorax. After the exam, a plain chest x raywas performed for the conformation of the findings. From 50 placed hemodialysis catheters, 47 were adequately placed. All catheters were identified with the use of ultrasound. The tip of the 3 misplaced catheters could not be detected with the use of ultrasound. No pneumothorax was observed. The average time for detection of correct catheter placement was much faster with the use of ultrasound compared with chest x ray (11,5min and 80 min, accordingly). The use of bedside ultrasound for conformation of central venous catheter placement and excluding pneumothorax is as accurate as with chest radiography, but it is can be done much faster.
