Assessment of fluid status in peritoneal dialysis patients.
OBJECTIVES To assess the influence of abnormalities in fluid status and body composition on agreement between multifrequency bioimpedance analysis (MF-BIA), segmental BIA (sigmaBIA), the Watson formula, and tracer dilution techniques. DESIGN Cross-sectional. SETTING Multicenter. PATIENTS 40 patients (29 males, 11 females) on peritoneal dialysis (PD). MAIN OUTCOME MEASURES Agreement betw...
متن کاملDevelopment of miniaturized, portable magnetic resonance relaxometry system for point-of-care medical diagnosis.
A novel, compact-sized (19 cm × 16 cm) and portable (500 g) magnetic resonance relaxometry system is designed and developed. We overcame several key engineering barriers so that magnetic resonance technology can be potentially used for disease diagnosis-monitoring in point-of-care settings, directly on biological cells and tissues. The whole system consists of a coin-sized permanent magnet (0.7...
متن کاملVasodilator response assessment in porcine myocardium with magnetic resonance relaxometry.
BACKGROUND This research describes an early preclinical study of the biophysical mechanisms governing changes in myocardial T2 during vasodilation in normal myocardium. METHODS AND RESULTS Theoretical modeling and experimental studies in an instrumented pig model (n=7) provided measures of changes in myocardial T2, relative blood volume (BV), and microcirculation oxygen levels (%O2) during in...
متن کاملIdentifying high and low serum-ascites albumin gradient in ascitic fluid by the point of care dipstick test
Objective: To evaluate the capability of ascitic fluid dipstick results for pH, glucose, and protein in order to predict a low serum-ascites albumin gradient (SAAG) at the bedside of the patient in the emergency department (ED). Methods: This prospective cross-sectional study was conducted during one year in the ED of Afzalipour hospital in Kerman, Iran. ...
