Providing additional education to hemodialysis patients on the specific cooking methods and accordingly prepared meals may decrease serum phosphate levels without significantly affecting nutritional status which may be useful in helping to prevent and treat hyperphosphatemia.

S obzirom na sve stariju populaciju pacijenata sa završnim stupnjem kronične bubrežne bolesti, a kako bi se na Listu čekanja uvrstilo što više pacijenata za presađivanje bubrega, potrebna je temeljitija i opširna obrada potencijalnih primatelja bubrežnog presatka. Nakon dijagnostičkih postupaka trebalo bi pokušati sa svim dostupnim terapijskim mogućnostima otklanjanja kontraindikacija. Nakon uvrštavanja na Listu čekanja, potencijalne primatelje potrebno je dalje pratiti i isključiti moguće kontraindikacije. U prilog ovome ide činjenica da je posljednjih godina sve manji broj apsolutnih kontraindikacija za presađivanje bubrega. Jednako važna je temeljita obrada potencijalnog darivatelja bubrežnog presatka jer omogućuje i olakšava samu odluku o presađivanju bubrega, kao i pripremu potencijalnog primatelja bubrega za operativni zahvat, odabir imunosupresivne terapije te daljnje postupke prije i nakon presađivanja bubrega. Cilj je što više pacijenata uvrstiti na Listu čekanja prije početka liječenja dijalizom (preemptivno presađivanje bubrega) te omogućiti presađivanje od živog darivatelja, jer dosadašnja istraživanja pokazuju kako se tada postižu najbolji rezultati.

Objective:The aim of our study was to compare the values of blood pressure (BP) and pulse pressure (PP) in the brachial artery and in the central aorta by outpatient non-invasive methods in different patients age groups and according to the presence of chronic renal disease and diabetes.Design and method:The study included 110 outpatients older than 18 years of age with diagnosed and treated arterial hypertension (AH), under the care of Clinical Hospital Centre Rijeka in the period from June 1 to December 1, 2021. Peripheral BP, PP, and central aortic pressure (CAP) were measured in all patients on the same day. The average values of peripheral arterial pressure and the corresponding PP were obtained by the method of continuous blood pressure monitoring (CBPM). CAP and associated PP were measured on the same day by the method of radial arterial tonometry. Patients were divided into three groups according to the age (18–44 years, group I; 45–64 years, group II, and > 65 years, group III). Systolic and diastolic peripheral blood pressure (SPBP, DPBP), systolic CAP and diastolic CAP (SCAP, DCAP), and both peripheral and central PP (PPP, CPP) were nalysed among groups and according to the presence of chronic kidney disease (CKD).Results:In total, 98 patients were nalysed (mean age 55,08 ± 15,52 years; 79,6% essential hypertension; diabetics 12,23%; 26,53% CKD; 48,98% men). There were significant positive correlations between SPBP and SCAP, DPBP and DCAP, and PPP and CPP in group I and group III. There was no significant correlation between SPBP and SCAP (r = 0,268), and there were significant correlations between DPBP and DCAP, and PPP and CPP in group II. According to the presence of CKD, there was no significant correlation between SPBP and SCAP (r = 0,104), and there were positive correlations between DPBP and DCAP, and PPP and CPP.Conclusions:There was no significant correlation between SPBP and SCAP in 45–65 years old and CKD group, which tells us in favor of the atherosclerosis variability in these patient groups, which was expected. Further research on greater number of patients should be done.

Malnutrition in vulnerable patient populations must be rapidly detected using techniques that are easy to incorporate into everyday clinical practice. The new recommendations defined the 7-point Subjective Global Assessment (SGA) as optimal for nutritional assessment in chronic kidney disease (CKD), while Geriatric Nutrition Risk Index (GNRI) demands additional examination in elderly. This study aimed to determine the accuracy of several concise tools used in the clinical practice and the correlation of this tools with functional method hand grip strength (HGS) in elderly patients with CKD. In this cross-sectional study, anthropometric and functional data for 50 elderly hemodialysis patients were analyzed using numerous survey-based tools for screening nutritional status (Malnutrition Screening Tool – MST, Nutritional Risk Screening 2002 - NRS2002, Malnutrition Universal Screening Tool - MUST, Mini Nutritional Assessment - MNA, GNRI), which we compared to the standard 7-point SGA nutritional assessment tool. The sensitivity, specificity, and accuracy of these tools for detecting malnutrition were compared with the standard by using receiver operating characteristic (ROC) curve analysis. 7-point SGA classified 36.6% of participants as well nourished, and 63.4% as mildly to moderately malnourished, while the simplest alternative methods showed lower accuracy, classifying much higher proportions of participants as well nourished (MST, 92.0%; NRS2002, 80.4%). MNA had the highest accuracy based on receiver operating characteristic curves. HGS correlated moderately with 7-point SGA (r = 0.331), MNA (r = 0.410), and GNRI (r = 0.320). Our small study suggests that MNA is the best tool for malnutrition risk screening in elderly with CKD. Combining HGS with concise tools, such as GNRI, may provide better results and unburden healthcare professionals.
