Aim.To assess the diagnostic value of N-terminal pro-B-type natriuretic peptide (NT-proBNP) in hemodialysis (HD) patients.Material and methods.A total of 80 patients over the age of 18 with an end-stage renal disease (ESRD) on HD were included in this study.NT-proBNP serum levels were measured for all patients in addition to traditional clinical an
Nonlinear Observability Algorithms with Known and Unknown Inputs: Analysis and Implementation
The observability of a dynamical system is affected by the presence of external inputs, either known (such as control actions) or unknown (disturbances).Inputs of unknown magnitude are especially detrimental for observability, and they also complicate its analysis.Hence, the availability of computational tools capable of analysing the observability
Incisionless Knee Synovectomy and Biopsy With Needle Arthroscope and Autologous Tissue Collector
Knee arthroscopy has evolved greatly from Yoga its inception in the 20th century.Arthroscopic synovectomy is performed in the case of infection or significant synovitis.We continue to develop more minimally invasive procedures, and the NanoScope (Arthrex, Naples, FL) has provided a new generation of possibilities.The system does not require the use
