Data Analysis of Impaired Renal and Cardiac Function Using a Combination of Standard Classifiers.

We examine the significance of the predictive potential of EPI cystatin C (EPI CysC) in combination with NTproBNP, sodium, and potassium in the evaluation of renal function in patients with cardiorenal syndrome using standard mathematical classification models from the domain of artificial intelligence. The criterion for the inclusion of subjects with combined impairment of heart and kidney function in the study was the presence of newly discovered or previously diagnosed clinically manifest cardiovascular disease and acute or chronic kidney disease in different stages of evolution. In this paper, five standard classifiers from the field of machine learning were used for the analysis of the obtained data: ensemble of neural networks (MLP), ensemble of -nearest neighbors (-NN) and naive Bayes classifier, decision tree, and a classifier based on logistic regression.

Is It Possible to Analyze Kidney Functions, Electrolytes and Volemia Using Artificial Intelligence?

Markers used in everyday clinical practice cannot distinguish between the permanent impairment of renal function. Sodium and potassium values and their interdependence are key parameters in addition to volemia for the assessment of cardiorenal balance. The aim of this study was to investigate volemia and electrolyte status from a clinical cardiorenal viewpoint under consideration of renal function utilizing artificial intelligence.

Platelet thrombus formation in patients with end-stage renal disease before and after hemodialysis as measured by the total thrombus-formation analysis system.

Background: Patients with end-stage renal disease (ESRD) receiving hemodialysis (HD) often experience bleeding. However, mechanisms behind this bleeding tendency are incompletely understood but may involve platelet dysfunction. We, therefore, studied platelet-dependent thrombus formation in flowing whole blood inside a microchip coated with collagen, and its association with circulating von Willebrand factor (VWF).

Risk factors for urosepsis in chronic kidney disease patients with urinary tract infections.

Occurrence of urosepsis is not uncommon following urinary tract infections (UTI). However, there is a lack of evidence explaining the risk factors predisposing to urosepsis in patients with chronic kidney disease (CKD). This retrospective study was undertaken to evaluate the incidence and possible risk factors for urosepsis among patients hospitalized with UTI in a cohort of CKD patients.

Renal dysfunction as intrahospital prognostic indicator in acute pulmonary embolism.

Background: Acute pulmonary embolism (PE), due to hemodynamic disturbances, may lead to multi-organ damage, including acute renal dysfunction. The aim of our study was to investigate the predictive role of renal dysfunction at admission regarding the short-term mortality and bleeding risk in hospitalized PE patients.

Methods: The retrospective cohort study included 1330 consecutive patients with PE.

Protein Carbonyl Content Is a Predictive Biomarker of Eccentric Left Ventricular Hypertrophy in Hemodialysis Patients.

High prevalence of left ventricular hypertrophy (LVH) and elevated oxidative stress are associated with poor outcomes in chronic hemodialysis patients. Abnormal left ventriculаr geomеtry and different geometric patterns play an important role as well. Our study analyzed the role of oxidative stress on myocardial remodeling in these patients.

Associations of Cardiovascular and All-Cause Mortality with Metabolic Syndrome in Hemodialysis Patients: A Prospective Single-Center Study.

Metabolic syndrome (MetS) is a cluster of risk factors, such as abdominal obesity, insulin resistance, dyslipidemia and hypertension, that together increase the risk of cardiovascular disease. Chronic hemodialysis (HD) patients have multiple comorbidities and many metabolic disorders, causing the frequent occurrence of metabolic syndrome. The goal of this study was to assess the prevalence of MetS in HD patients, and its association with all-cause and cardiovascular (CV) mortality.

Elevated Serum Ferritin Levels Are Predictive of Renal Function Recovery among Patients with Acute Kidney Injury.

Oxidative stress (OS) frequently contributes to the development of acute kidney injury (AKI). Iron can promote oxidative stress and tissue injury by catalyzing free reactive oxygen species (ROS) generation and increasing the steady-state concentration of these potent oxidants. The anticipated role of ferritin is to protect from OS by sequestering iron and limiting its involvement in reactions that generate ROS.

Population Pharmacokinetics of Bisoprolol in Hemodialysis Patients with Hypertension.

The aim of our study was to estimate clearance of bisoprolol and reveal the factors that could influence its pharmacokinetic (PK) variability in hypertensive patients on hemodialysis, using the population PK analysis. Parameters associated with plasma concentration of bisoprolol at steady state were analyzed in 63 patients (mean age 62.12 years, mean total weight 69.

Comparative analysis of autodermal graft and polypropylene mesh use in large incisional hernia defects reconstruction.

Background: Large defects of the abdominal wall caused by incisional hernia still represent a challenging problem in plastic, reconstructive, and abdominal surgery. For their successful tension-free repair a proper selection of reconstructive material is essential. In the last decades, the use of synthetic meshes was dominant while biological autodermal grafts were rarely used.

How the duration period of erythropoietin treatment influences the oxidative status of hemodialysis patients.

Background: End-stage renal disease is a state of enhanced oxidative stress (OS) and hemodialysis (HD) and renal anemia further augment this disbalance. Anemia correction with erythropoietin (EPO) may improve oxidative status. However, there is no evidence of time dependent effects of EPO therapy on redox status of HD patients.

Indirect serum fibrosis markers in hepatitis C virus (HCV) infection.

Unlabelled: Assessment of liver fibrosis is important for making treatment decisions, as well as for predicting prognosis and therapeutic outcome in patients on chronic hemodialysis (HD) treatment and infected with hepatitis C virus (HCV). The aim of the present investigation was to evaluate changes in standard laboratory tests (AST, ALT, yGT, cholesterol and platelet count) and indirect serum fibrosis markers: AST-to-platelet ratio index (APRI), FIB-4 and Forns index, in chronically HCV-infected patients on maintenance HD with and without antiviral treatment.

Patients And Methods: A total of 38 patients on chronic HD program more than 3 months and with chronic hepatitis C, were included in the study.

Prevalence and risk factors of myocardial remodeling in hemodialysis patients.

Background: Left ventricular hypertrophy (LVH) is an independent risk factor for morbidity/mortality in patients with end stage renal disease (ESRD). Our study aimed to identify prevalence as well as independent risk factors that contribute to the development of LV geometric remodeling in our HD patients.

Methods: The left ventricles of 116 HD patients were classified echocardiographically into four different geometric patterns on the basis of LV mass and relative wall thickness.
