Revised equations for estimated glomerular filtration rate (eGFR) were published in 2021 using creatinine (eGFR-Cr) and both cystatin C (eGFR-Cr/CysC). This study aimed to evaluate the prognostic role of eGFR incorporating patients with heart failure (HF). The NZ PEOPLE is a prospective cohort HF. Cystatin immunoassays performed on stored plasma samples. eGFR-Cr eGFR-Cr/CysC calculated. Four-ye...

To determine the validity of endogenous creatinine clearance as a measure of glomerular filtration rate in patients with renal disease 308 simultaneous determinations of inulin clearance and endogenous creatinine clearance were reviewed and analysed. The ratio of creatinine clearance/inulin clearance increased progressively with the decline in inulin clearance, while the finding of a normal end...

The relation between surface area and body weight changes dramatically in infancy. In 31 healthy infants of 27 to 40 weeks' gestation, variations in glomerular filtration rate were reduced more than twofold by choosing glomerular filtration rate/kg body weight rather than glomerular filtration rate/m2. The former provides the most useful and practical index of renal function in the neonate.

Downward and upward ultrafiltration (UF) was performed using the suspensions of nanosized colloidal silica with different particle diameters and their filtration rates were compared. In downward UF, the filtration rate decreases as the particle diameter decreases because the specific filtration resistance of the filter cake becomes significantly higher. In contrast, the filtration rate in upwar...

Abstract Background The ratio of early diastolic inflow to strain rate, E/e'sr, is a novel echocardiographic measure, which has been shown correlate better with left ventricular (LV) filling pressures than the conventionally used E/e' (1). Additionally, E/e'sr demonstrated prognostic value in various patient populations (2). Patients chronic kidney disease (CKD) suffer frequently dysfunction an...

OBJECTIVE Pneumoperitoneum during laparoscopy results in transient oliguria and decreased glomerular filtration and renal blood flow. The presence of oliguria and elevated serum creatinine is suggestive of acute renal injury. Serum cystatin C has been described as a new marker for the detection of this type of injury. In this study, our aim was to compare the glomerular filtration rate estimate...

BACKGROUND Chronic kidney disease (CKD) is associated with substantial burden and is a strong risk factor for cardiovascular disease. However, data on the relationship between CKD and stroke are few and are limited by unreliable or inadequate assessment of renal function. OBJECTIVE To properly assess the relationship between renal insufficiency and stroke in stroke survivors in the United Sta...

1. Effective renal plasma flow, glomerular filtration rate and cardiac output were measured in osmotically loaded dogs before and during comparable acute respiratory and metabolic acidosis. 2. Urine output increased in control dogs and in animals with metabolic acidosis, but declined with respiratory acidosis. Effective renal plasma flow and glomerular filtration rate declined with respiratory ...
